Plastic mold accessories include various parts and components, and the following are some common accessories:

1. Gate sleeve: The gate sleeve is the entrance in the mold that guides molten plastic into the mold cavity. They are usually made of materials that are resistant to high pressure, high temperature, and wear, such as steel and hard alloys.

2. Mold spring: Mold springs are used to provide the force for mold opening or splitting, as well as to maintain the tight closure of the mold during injection molding.

3. Mold screws: Mold screws are used for fixing and connecting molds. They need to have high strength and corrosion resistance.

4. Positioning ring: The positioning ring is used to ensure the correct position of the mold in the injection machine and prevent mold displacement during the injection process.

5. Pull rod: The pull rod is the main structure of the mold, used to fix various parts of the mold. The pull rod needs to have high strength and corrosion resistance.

6. Wear resistant plate: Wear resistant plates are used for the easily worn parts of molds, such as cores and cavities, to improve the service life of molds.

7. Ejector: The ejector is used to eject the finished product from the mold after injection is complete. The ejector is usually made of high-strength steel or hard alloy.

8. Gate: The gate is a channel that guides molten plastic into the mold cavity. The size and shape of the sprue have a significant impact on the quality of injection molding.

9. Cooling water pipe: The cooling water pipe is used to cool the mold during the injection process, in order to accelerate the production cycle and improve product quality.

10. Barrel: Barrel is used to control the height and position of the finished product during the injection process.

The above is only a part of the plastic mold accessories. The specific types and quantities of accessories depend on the design and requirements of the mold.
