How many parts does the molding tool consist of?What does it do?
Injection molding mold structure can be divided into the following several parts: the injection parts molding parts, mold clamping part, introduction part of the products, core spare parts, mould heating and cooling part of concrete, concrete supporting part and injection mold, the exhaust channel, etc.
The forming part.It is the part of the cavity that forms the plastic products directly after the mold is assembled and formed. There are punch, die, core, rod or insert.
The model guide section.It is the parts that can be set up correctly to align the center axis with the moving and fixed mold closing mode, with guide column, guide hole sleeve or bevel cone.
Part of the product launch.It is the parts that are used in molding injection moulds from moulds cavity, with ejector rod, fixed plate, push plate and pad.
The core extraction part.Injection molding plastics demoulding pits or side with a hole, the first drew indentation, side hole forming with the core of body parts, such as application of oblique guide pillar and often technoloy and bent pin core-pulling mechanism, etc.
The specific heating and cooling parts of the mold.It refers to the control system for the injection molding process temperature of plastic products, such as resistance heating plate, rod and electric control element;The cooling part is used for circulating cooling water pipes.
The concrete supporting part of the forming die.It refers to the auxiliary parts, such as moving, mould plate, positioning ring, lifting ring and various fastening screws, to ensure the correct work of the mould.
The cast-in-place melt channel refers to the flow passage that can direct the melt material injected by the nozzle into the cavity of the mold cavity, which can be divided into the main channel, the shunt channel, the liner mouth (gate) and the cold feed tank.
The vent hole is the part that can make the air out of the mold cavity.Generally small products can not be specially equipped with vent holes, the air in the cavity can be discharged from the clearance of each mating part;For large injection moulds, there must be a vent set.
