Description

Technical Field

[0001] This utility model relates to the field of die casting production technology, and in particular to a die casting mold for an aluminum pump body. Background Technology

[0002] The pump body is a crucial component of a pump, a type of mechanical device. It typically refers to the outer shell structure that houses and supports the internal components of the pump, providing the necessary space and flow channels for the working medium. Its basic function is to work in conjunction with the impeller, piston, or plunger to change the pressure or flow rate of the working medium, enabling the medium to be transported from a low-pressure area to a high-pressure area or to circulate, thus meeting the fluid transport, pressurization, or circulation needs in various industrial or civil applications. As the core load-bearing component of the pump, the rational selection of its structure, material, and type directly affects the pump's performance, reliability, and applicability. It plays a vital role in fluid transport and processing in numerous fields and is widely used; therefore, die-casting molds for pump bodies are required in their manufacturing.

[0003] Currently available die-casting molds for pump bodies mainly consist of a fixed mold, a moving mold, and a limiting block. During use, the moving and fixed molds close, and molten metal is injected into the mold cavity through the sprue. After a certain period of solidification, the moving and fixed molds separate. Once a certain distance has been separated, the ejection mechanism activates, using push rods to eject the formed pump body from the mold cavity, allowing for easy removal by operators. However, if the layout and ejection method of the ejection mechanism do not conform to the shape characteristics and demolding requirements of the pump body, deformation, cracking, or ejection marks can easily occur during ejection, affecting product quality. To address these issues, existing technologies only employ push plate ejection or multi-point evenly distributed push rod ejection for thin-walled pump bodies to disperse ejection stress, without adding a cooling structure. This results in excessively long cooling times, impacting production efficiency, wasting resources, and failing to meet user needs. Utility Model Content
