Typical structure of precision injection mold:

1. Mold parts

The cavity is formed directly, and the parts of plastic parts are usually made up of male mold and female mold.

2. Casting system

The plastic flow from the nozzle with little jet flow to the cavity is called the gating system.

3. Guide part.

In order to ensure the accuracy of the mid-plane guide rail components in the case of dynamic and constant mode combination, there are usually guiding column (GP), positioning block, ejection guide column (EGP) and so on.

4, split core pulling mechanism

Before removing the side holes or plastic parts on the side surface, they must be separated before they can be released smoothly. Commonly used mechanisms are: slide block cavity (including main mode core pulling block, explosive slide block), pin and so on.

5. Jacking up equipment

A device for ejecting plastic parts from the mold during the mold opening process.

6. Cooling and heating system

In order to meet the requirements of injection molding process for mould temperature, the mould has cooling or heating system. Usually, cooling channels, heating or oil substances are provided in the mold.
