Composition injection mold design

1, molded parts

Given the shape of the molding material, the structure, the size of the parts, usually consists of core (punch), concave cavity and threaded core, inserts and other accessories.

2, gating system

It is the molten plastic injection MASTER injection mold maker‍ nozzle toward passage by the closed mold cavity, usually by the sprue, runner, gate and cold slug well composed.

3, the guide member

In order to ensure the guide member when the movable mold and the mold is closed can be accurately aligned and set, from the positioning guide action by the guide column and which is composed of the guide sleeve, the top of the panel there is also provided a mold of the guide member, to ensure ejection mechanism is smooth and reliable movement.

4, stripping mechanism

Realization of plastic MASTER plastic drawer mold‍ and mold gating system device, a lot of its structure, the most commonly used plunger, pipe jacking, such as the top of the roof and pneumatic ejection mechanism, generally by the mandrel, reset lever, slingshots, ejector fixing plate roof (top ring) and roof pillar / bushings and other components.

5, core-pulling mechanism

For concave side holes or side plastic parts, was the top before stripping must be separated laterally Pulling or slider (lateral type) in order to successfully mold.
