In order to ensure product quality and mold safety, a latent gate is set on the side of the moving mold and a second gate is set on the flat thimble to make the melt enter the mold cavity from the flat thimble and avoid the gate mark on the side of the plastic part. When the mold is opened, due to the large demoulding resistance of the main channel and the shunt channel, the pour material of the gating system will stay in the fixed mold side, while the plastic part will stay in the moving mold side, causing strain to the plastic part. Therefore, reference point gate three - plate mold fixed mold casting system condensate automatic demoulding structure. The mould resistance of the plastic part comes from the shrinkage of the plastic part and the internal structure of the plastic part. The inclined top mechanism ejects the plastic parts at the same time when the die is released from the inner buckle; Each inclined top mechanism is fixed on the thimble panel, and the plastic parts are pushed out together with the push out system. In order to ensure the safety of the reset after the inclined top pushes out the plastic parts, the spring reset mechanism is set in the mold. Die steel for hot abrasive steel, with good toughness and high temperature fatigue resistance, suitable for manufacturing thimble, barrel, inclined roof and other parts; If the plastic part is a big strip knot, the cooling should be strengthened, and the cooling system should arrange waterways according to the shape of the plastic part.
Plastic injection mold (Plastic injection mold making) using steel as the material, injection mold internal structure is based on the product design to complete can be customized according to the needs of products. The internal structure of the injection mold is clear. The concave and convex surface can check the contour of the product.
