Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a water tank mold that can be prevented from being broken when ejected from the mold. Background Art

[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by injection moulding, blow moulding, extrusion, die casting or forging, smelting, stamping and other methods. In short, moulds are tools used to make shaped objects. Existing water tank moulds still have certain defects when used, such as;

[0003] Existing water tank molds mainly use cooling pipes for cooling. However, the cooling system of the existing cooling pipes has poor fluidity and slow cooling time. When the water tank in the mold is taken out, it is easy to deform or even break. The cooling is slow. In addition, when the existing water tank mold is injected with an injection molding machine, some residual material is easy to be generated, which can easily cause the injection port to be blocked and even affect the aesthetics of the product. However, most existing water tank molds cannot cut the residual material. Utility Model Content
