[0004] The purpose of this invention is to provide a special mold for housings. It solves the problem that high-quality forming at the edge of large through holes leads to reduced product lifespan.

[0005] To achieve the above objectives, the solution adopted by this utility model is: a special mold for a shell cover, including a moving mold assembly, an ejection assembly, a fixed mold assembly, a first slider assembly and a second slider assembly arranged opposite to each other, wherein the moving mold assembly and the fixed mold assembly are closed to form a molding cavity, the first slider assembly includes a first protrusion arranged at intervals, the second slider assembly includes a second protrusion arranged at intervals, and the first protrusion and the second protrusion are closed and abutted together;

[0006] The moving mold assembly includes an upper molding block, and the fixed mold assembly includes a lower molding block. The upper molding block and the lower molding block close together and abut against each other, forming an intermediate molding area in the molding cavity. The intermediate molding area has at least one intermediate molten pool.

[0007] The protruding direction of the upper forming block is perpendicular to the protruding direction of the first protruding post.

[0008] In this design, a shell can be formed within the intermediate forming zone created by a fixed mold assembly and a moving mold assembly, formed by the upper and lower forming blocks. Furthermore, the inclusion of a first and second slider assembly facilitates the forming of the central portion located at the edge of the large through-hole. The intermediate forming zone maintains the central temperature, allowing for more frequent heat exchange at the edge, resulting in higher forming quality and increased product lifespan. The intermediate molten pool effectively holds the molten metal, further enhancing the quality of the formed central portion at the edge of the large through-hole.

[0009] As a further preferred embodiment, four intermediate molten pools are provided, and the four intermediate molten pools are symmetrically distributed.

[0010] Preferably, the moving mold assembly includes a main runner, which has two symmetrically arranged branch runners that connect to both sides of the intermediate molding area.

[0011] Preferably, the moving mold assembly includes two slag-filling grooves, which are connected to both sides of the intermediate forming zone.

[0012] In this scheme, the molten oxidized material can be conveniently stored by setting up a slag-scraping tank.

[0014] As a further preferred embodiment, the moving mold assembly is provided with an inclined insert block, and the first slider assembly and the second slider assembly are provided with slots with the same inclination as the insert block for the insert block to be inserted. When the moving mold assembly and the fixed mold assembly are closed, the first slider assembly and the second slider assembly are driven to move towards each other.

[0015] In this solution, by setting the insert block to be inserted into the slot, when the moving mold assembly moves and the fixed mold assembly closes the mold, the first slider assembly and the second slider assembly are brought closer to each other, thereby forming the intermediate forming area forming cover.

[0016] As a further preferred embodiment, both the first slider assembly and the second slider assembly include a movable block and a slider. The fixed mold assembly is provided with a slide rail, and the movable block is slidably disposed on the slide rail. The movable block is provided on the side of the two sliders that are far apart from each other, and a first protrusion and a second protrusion are respectively provided on the side of the two sliders that are close to each other. The slot is disposed on the movable block.

[0017] In this solution, by setting a movable block, the movement of the moving mold assembly drives the movable block to move, thereby driving the slider to move; and by setting a first protrusion and a second protrusion that close together, they are respectively used to form the first through hole and the second through hole.

[0018] Preferably, the ejection mechanism includes an ejection plate and ejection rods. The ejection plate is provided on the fixed mold assembly, and a plurality of ejection rods communicating with the molding cavity are provided on the upper end of the ejection plate. Each intermediate molten pool is connected to one ejection rod.

[0019] In this solution, an ejector plate and ejector rod are used to eject the molded cover from the fixed mold assembly, making it easy for operators to remove.

[0020] Preferably, the mold assembly is provided with a pouring port that communicates with the intermediate molding zone.

[0021] In this scheme, the shell is formed by pouring molten liquid into the molding cavity through a pouring port.
