The push rod fixed seat, the fourth screw is connected to the push rod fixed plate, the slider guide plate is connected to the inclined push rod fixed seat, the inclined push rod fixed seat is connected to the push plate, the fifth screw is nailed into the movable formwork through the movable formwork seat plate; the water pipe joint and the mold A sealing ring is arranged between the cavity blocks.

Adopt above-mentioned technical scheme, the beneficial effect of the utility model is:

The utility model has the advantages of reasonable structure, stable work, high production efficiency and qualified product quality. It adopts a latent gate to avoid gate traces on the appearance of the product. By adopting a circulating cooling system, the temperature difference between various parts of the mold is reduced and the mold is improved. The cooling efficiency reduces the warping deformation of the product; through the design of the inclined push rod device, the lateral core-pulling of the inner side of the product is realized, which simplifies the mold structure and has good economy.
