The structure of the injection mould

The composition of a plastic mold is divided into a lot of links, to ensure the quality of the mould are to be control from each link, here is to share with you the plastic mold of common structure and system, hoping to bring help! Taizhou mould for your analysis of injection mold structure and

1, molding parts give molding material shape, structure, size of the parts, usually by the core ( Punch) , concave model cavity and thread core, blocks, etc.

2, pouring system it is the direct melting plastic by injection machine nozzle closure cavity, usually by the mainstream way, distributary channel, gate and the cold slug well.

3, guide components in order to guarantee the dynamic model with the die closed to perfect alignment and orientation arrangement of components, function orientation, positioning, it is composed of guide pillar and guide bush, some mold has set up a guide on the ejector plate parts, ensure the demoulding mechanism motion stable and reliable. Demoulding mechanism
4.
parts and gating system implementation in ejection device, the structure form of many, the most commonly used are push rod, pipe jacking, roof and pneumatic demoulding mechanism, such as general by the plunger, reset pole, slingshot, plunger, fixed plate, roof ( The top ring) Guide pillar and the roof/guide sleeve, etc.

5, core-pulling mechanism for the lateral concave side holes or plastic parts, before being ejector demoulding, must first for lateral core-pulling or separate slider ( Lateral type) To smooth demoulding.

6, die temperature regulating system in order to meet the requirements of injection molding process of mould temperature, need to have a mold temperature adjusting system ( Such as: cooling water, hot water, hot oil and electric heating system, etc. ) The mold temperature adjusting device.

7, exhaust system to the gas discharge smoothly within the cavity, often open the exhaust slot in the mold parting surface, many die push rod or other moving parts ( Such as: the slider) The gap between the can also play a role of exhaust.

8, other structural parts is set up to meet the requirements of die structure on parts ( Such as: fixed plate, moving/templates, hold the head, supporting plate and connecting screws, etc. ) 。
