Influence of mold temperature control on the processing of silicone
liquid mold
Liquid silica gel is a thermosetting material. The curing reaction
of liquid silica gel injection mold occurs at the mold temperature
of 120-150 ℃, and the mold temperature control is very important.
1. Mold surface temperature should be stable
If the surface temperature is too high, the products will be
scorched, the parting line will crack, and the products will become
brittle.
If the surface temperature is too low, the curing speed of rubber
compound is slow, and the product can not be demoulded;
2. The temperature of the mould should be heated evenly
The uneven heating and large temperature difference of the mold
will make the rubber flow unstable, which is easy to cause air
entrapment and insufficient injection
3. Location of heater
Sufficient distance should be kept between the heater and parting
line to prevent the template from warping and deformation,
resulting in overflow burr of finished products;
4. Comparison of mold temperature control heating methods
1) Heating of heating rod:
The heating rod is drilled by gun drill. The gap between the
heating rod and the hole will lead to uneven heat transfer, and the
heating rod is easy to be damaged. Moreover, multiple groups of
heating rods share a set of temperature sensing, so the damage of
the heating rod cannot be detected and the mold temperature is
uneven. Choose carefully.
2) Heating plate heating:
The heating plate is designed at the bottom of the mold core, which
is close to the mold core. The heating plate is designed with
independent temperature sensing and closed-loop design to ensure
that the temperature is controllable and the temperature of the
heating plate is uniform. Recommended.
TYM machine features
1) Full range of permanent magnet synchronous high response servo
motors, quick response time of hydraulic. The flow of power’s
output is as same as the flow of executive, no high-pressure
throttling losses.
2) Static mixer can mix the A and B component LSR material very
adequately, which can supply better quality assurance for the LSR
product producing.
3) Excellent-quality oil pump, proportional valve, magnetic valve
from world famous brand, which can guarantee excellent control on
the hydraulic function.
4) Brand new TYM series controller, parameterized settings,
multigroup electronic ruler to monitor the execution on every
action, which can guarantee the reliability, stability and accuracy
of the machine’s operation.
5) Self-research direct pressure injection barrel, which is more
suitable for the moulding process of the LSR material.
6) Self- research full stainless steel pumping unit and ration
pump, which can guarantee high accurate proportion of 1:1(A:B) to
feed the material.
