[0046] Working principle:

[0047] When it is necessary to produce shell products, first install the entire mold on the die-casting machine, and then debug it. After debugging is completed, first close the upper mold plate 1 and the lower mold plate 2 as well as the upper mold core 31 and the lower mold core 32, and the hydraulic cylinder 71 drives the slider seat 74 to drive the slider head 75 to move, so that the four slider heads 75 gather together. After completion, inject molten raw materials into the mold cavity, and the molten raw materials enter the mold cavity from the barrel. When the molten raw materials fill the mold cavity, the pressure is maintained in the mold by the die-casting machine, and cooling water is introduced into the water inlet. The cooling water is diverted in the cooling chamber 9 to increase the cooling area and improve the cooling efficiency. After absorbing heat, the cooling water becomes hot water and flows out from the water outlet to ensure the cooling effect and production efficiency. After cooling, the mold is opened, the upper mold plate 1 and the upper mold core 31 move up, and the hydraulic cylinder 71 drives the slider seat 74 to drive the slider head 75 to move, so that the four slider heads 75 are away from the lower mold core 32, and the four slider heads 75 are separated from the product, and then the top plate 81 is pushed to drive the ejector pin 82 to move up, and the lower mold core 32 is ejected to remove the product.

[0048] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
