Chapter 8 Installation of Mould

For the different construction of mould, we should unload the upper mould
plate or change the position, the way of re-install mould is as followings.
(1). Tighten the upper mould, put the lower mould with bolt in base.
(2). Put the ball wheel in the work surface of forming, adjust the upper mould
base and tighten nuts, the distance of cutter, between upper and lower
mould is 0.5-1mm, revise it then tighter screw.
(3). Adjust stem ball wheel base of stem to make cutter coincide upper and
lower mould cutter coincide, which is 1/3 of sheet, then lock tightly top
stem and lower mould.
(4). Rotate the main cam 2-3 cycles by manual handle try to operate the
machine without mal-position.

Positive-pressure thermoforming mould plays an essential role in

production, so it is so important to maintain it in a right way.
At present, positive-pressure thermoforming mould for disposable cup
production applies the configuration of molding integrated with punching.
Mainly it has the following characteristics,
·The upper and lower cutter functions to punching, and some of the lower
can even help form the product’ edge.
·The upper and lower cutter is usually fixed. Cavities can be changed
optionally, so one set of mould can be used to manufacture different kinds of
plastic cups, which can lower the cost, speed up mould’s changing, and
improve the production efficiency.
·Apply the way of stretching by die plug and formed by compressed air

Tel: 0086-577-65139801 Zhejiang Honghua Machinery Co.,Ltd Fax: 0086-577-65139807

·The upper and lower cutter can work 1-5 million times. The dull cutter
can be used repeatedly after being ground.
Therefore, during the production of “disposal plastic cup”, the
consequence from the situation of maintaining directly influences production
efficiency and quality, which turns out that the effective maintainment is
specially critical.
Suggestion as follows:
· It is better to install the thermoforming mould on the suited
positive-pressure thermoforming machine. Because, if the mould is changed
frequently, it will not only reduce the production efficiency, but also increase
the damage possibility during the course of disassembly, storing, installing,
and commissioning, so that the fit accuracy will certainly lower gradually,
effecting the product quality and production efficiency.
The installing and commissioning methods described below is referenced
upon the cam positive pressure thermoforming machine。
1. The steps of mould installation and commissioning:
· Use a clean duster cloth to clean the installing surface of the upper
mould base and the installing surface of the upper mould, spray equal
antirust oil, and smear transparent food-grade lube ointment onto pulled rods
for die plug.
·Install the upper mould onto the upper mould base, leaving locknuts
loose to adjust the knives position when closing the mould.
·Retract die plug inside the upper cutters.
·Use a clean duster cloth to clean the installing surface of the lower
mould base and the installing surface of the lower mould, spray equal
antirust oil, and smear transparent food-grade lube ointment onto the mould
rods.
·Install the lower mould onto the lower mould base, leaving locknuts
loose.
·Jog the jigger to make the lower mould rise to forming position (radius
arc), fasten nuts through adjusting the upper mould base (macro-adjustment),
then adjust screw rod nuts or inclined plate of the lower mould base
(micro-adjustment), to control the horizontal distance between the upper and
lower cutter is 1/3-1/5 of the material thickness. Sometimes, the upper cutter
can go into the lower, which is referred to the configuration of the knives
and mould.

Tel: 0086-577-65139801 Zhejiang Honghua Machinery Co.,Ltd Fax: 0086-577-65139807

·Jog the jigger to the cutting position, to make the lower cutter go into the
upper cutter.
· Lock the mould bolts tightly: the upper mould first, then the lower
mould, from inside to outside, then diagonal. In order to ensure the mould to
get an even force, suggest using the proper torque wrench according to the
bolts.
·Fix correctly the cooling water pipe and air pipe.
·As to the thermoforming machine which is worked by angle control
system, set the starting and stopping angles of plunger, molding air, air
blowing, material feeding and so on, to confirm the operative procedure and
the length of time.
·Macro-adjustment on the procedure can base on the usual program
control diagram, because it results from summarizing a large number of the
practical production, which takes some generality. For the micro-adjustment,
· Adjust die plug descending depth, thermoforming air pressure,
material-feeding width, material-in width, material-out width, heating
temperature, and cooling water flux or velocity, or set the cooling
temperature if using the Mould Tem. Controller.
·In general, the depth for die plugs descending (H):
Descending depth (H) = product’ depth (H1) – h (usually 3-5mm)
·Rows of holes for cutters, cavities, bottom ejector plate on the lower
mould should keep free.
·Check whether those settings are correct under the condition of no
materials and low speed operation or through jogging handling.
·Feed the materials to test the machine when making a micro-adjustment
on the machine, mould, technical parameters until normal production.
2．Mould cooling and protection during the production.
·In order to retain the most production efficiency, please try to keep the
mould temperature low, and this is related to the materials and thickness
which are used in the production.
·If the most common used materials, such as PS, PVC, PP, ABS, are
applied in the production, 16--18℃ is the typical temperature, while the
mould should not be under 10℃, because the produced condensed water will
influence the product quality and cause the mould rusty.
· High temperature will lower the production efficiency, so the
temperature for thermoforming machine should not exceed 30℃.
Web: http://www.honghua.com 26 E-mail: honhua@mail.wzptt.zj.cn
Tel: 0086-577-65139801 Zhejiang Honghua Machinery Co.,Ltd Fax: 0086-577-65139807

·Plenty of cooling water flows through the mould, which is the key to get
a constant temperature during the whole operation. The flux should be
80L/Min.
·It is important to make the upper and lower mould hold the same
temperature. Otherwise, different thermal expansion will partly make the
knives of cutters splitting, make the cutters and guide rod abraded earlier, to
lower their life.
·In general, the temperature difference between the upper cutter and the
lower should not exceed 5℃.
·Cooling water should go through the ejector base of mould. Once the
size is smaller, please apply another cooling way for the base.
·In general, stick a thick felt (3—8mm) onto the surfaces of the lower and
upper mould bases, which are close to the heater. This is to stop the heat to
transfer to the mould, because the heat will cause the different temperatures
of the whole mould, which doesn’t only distort the mould, but also affect the
cooling purpose and product quality.
·Before starting the machine, please check whether heating tiles are
fixable, especially the top ones, clear up sundries and tools around the
machine, in order to keep them from dropping into the mould to break the
cutters during the production.
·When the power is off, the upper and lower mould should be closed in
the forming position (radius arc) to prevent those foreign objects dropping
into the mould.
3．Maintainment and lubricating
In order to keep the mould in a state of the smooth production without
malfunction, a periodic duty maintainment should be carried out exactly.
·Each 8 hours, all the lubricating point, such as oil jet should be
maintained once.
·Check whether there are scars on the lineal guide bearing bush. If yes,
please check the reason.
·Each week, add lube into the lineal guide bearing bush twice.
·Each 8 hours, smear food-grade lube.
·Each 8 hours, smear lube onto the ejector rod.
·Each 16 hours, check whether the locknuts on the ejector rod and die
plug rod are loose.
·Each 8 hours, clean the upper and lower mould with air gun when the
Web: http://www.honghua.com 27 E-mail: honhua@mail.wzptt.zj.cn
Tel: 0086-577-65139801 Zhejiang Honghua Machinery Co.,Ltd Fax: 0086-577-65139807

mould should be at the lowest position.

A. Clean out the deposit hidden under the ejector plate.
B. Lower the die plug, and remove fragmentized plastic interlarded with
the pressing circle.
·Each day, check with eyes the pressure of cooling system and water flux.
If using the pollutant water for cooling, please clean cooling system every 3
months. Once there is dirty deposit, add equal detergent into solvent, or
change cooling water at stated intervals.
·Each week, check the abrasion condition of die plug. Their figures will
change because of abrasion and the products will be influenced, so please
prepare enough spare die plugs.
·Each 8 hours, check whether the die plug is loose or not, such as
locknut’s condition, and check whether it is on the same level with level
ruler.
4．Mould storing
·Mould should be stored in the dry room with air-condition. If there is too
much humidity in the room, please use vaseline or antirust on all the shining
surface as protection.
·If there is enough space, please divide the mould into two parts to be
placed separately. Attention to keep the die plug pulled rod and ejector rod
upwards straight. This storing way can avoid the guiding mechanism
slanting and distorting, so that knives on the mould can be protected.
·If the mould can not be placed by two parts, please set it straight on the
special shelf, putting a flat board between the upper cutters and the lower, in
order to protect cutters from abrasion because of too much close biting.
·Please remove the cooling water out of the mould through aqueduct or
hole, such as using compress air. Especially in winter, when the mould is
stored in the room which is not anti-frost, any cooling water left in the
aqueduct might bring damage to the mould.
５．Maintaining
·The knives of cutters and other mechanical parts of the mould are all
easy to be worn.
·In order to prolong the lifespan, the cutters will be produced longer a
little bit, so as to be ground for more times in the future. Please try to make
the cutting position (high step of cam) lower, to stop the lower cutter not to
bite the upper too much, reducing the abrasion.

Tel: 0086-577-65139801 Zhejiang Honghua Machinery Co.,Ltd Fax: 0086-577-65139807

·If repair the broken cutter with metal-filled way, such as welding, knives
will distort or crush. In order to be convenient for maintaining and ensure
the quality, the hardness of the upper cutter should be less than the lower in
processing. In general, the hardness for the upper is 55-58HRC, the lower
60-65HRC.
·Based on materials that the upper cutter is rubbed out, the front of
pressing circle in the mould body might be re-processed, such as being
ground thinner. But anyway, please ensure enough space for the circle which
is topped by the spring to be retracted. At least the distance for this retraction
should equal to machine’s cutting depth (in general, it is 2.0-2.5mm,
different in different machine).
·In most of moulds, the lower cutter will also function to form in some
sense, so please remember that only if the cup’s shape changes or size
changes or other mould components are re-processed at the same time, the
lower cutter can be ground within the high precision tolerance.
·Any abrasion for the height may require making new cavities and ejector
plate, in order to make sure that the product size and shape is not changed.
·If the cutter knives need to be re-ground, please examine the abrasion
situation of other mould components. If necessary, please change those
abraded and unqualified ones, including seal rings for all the mechanical
parts, ejector rod, die plug, plug rod bush, and cavities for ejection function.
Notice: if the new lower cutter is installed, please re-install the guiding
and position components.
——Fix new aligning pin, guiding bush and guiding rod on the upper
mould.
——Fix new aligning pin, guiding bush and guiding rod on the lower
mould.
· The operation above requires the competent experienced workers
handling inside the mould workshop which is equipped well and is suitable
for maintaining. If it is not sufficient in maintaining people and tooling
condition, please send the mould to the supplier for examination, in order to
avoid ruining the mould.

2.2 Remedies for alarms

When any alarm has occurred, eliminate its cause, ensure safety, then reset the
alarm, and restart operation. Otherwise, injury may occur.
CAUTION If an absolute position erase (AL.25) occurred, always make home position setting
again. Otherwise, misoperation may occur.
As soon as an alarm occurs, turn off Servo-on (SON) and power off.

POINT
When any of the following alarms has occurred, do not deactivate the alarm
and resume operation repeatedly. To do so will cause the servo amplifier/servo
motor to fail. Remove the cause of occurrence, and leave a cooling time of
more than 30 minutes before resuming operation.
Regenerative error (AL.30)
Overload 1 (AL.50)
Overload 2 (AL.51)
The alarm can be deactivated by switching power off, then on press the "SET"
button on the current alarm screen or by turning on the reset (RES). For details,
refer to Section 9.2.

When an alarm occurs, the trouble (ALM) switches off and the dynamic brake is operated to stop the
servomotor. At this time, the display indicates the alarm No.
The servo motor comes to a stop. Remove the cause of the alarm in accordance with this section. The optional
MR Configulator (servo configuration software) may be used to refer to the cause.
