Problems solved by technology

[0002] The new energy water-cooled motor housing end cover is an important part of the new energy vehicle engine. The gravity casting process design of the general new energy motor housing end cover is complex in structure, low in efficiency, poor in product quality, and low in mechanical properties. The casting molding system is from Side casting, with the development of the times, the improvement of industrial production efficiency and the requirement of low work intensity for employees, the existing general new energy water-cooled motor casing end cover mold casting design process can no longer meet the industrial production needs

Embodiment 1

[0025] Such as Figure 1-2 As shown, the gravity casting mold for the end cover of the new energy water-cooled motor housing includes an upper mold 5 and a lower mold 8, and the upper mold 5 and the lower mold 8 form a mold cavity 19 after mold closing, and the upper mold 5 is provided with The upper mold fixed plate 1, the upper mold fixed plate 1 is fixedly connected with the upper mold 5 through the upper mold connecting rod 2, the center of the upper mold 5 is provided with a gate 16, and the gate 16 is surrounded by a sprue sleeve 3, and the sprue sleeve 3 is installed on the sprue sleeve positioning ring 4, the sprue sleeve positioning ring 4 is fixed on the upper mold 5, and the edge of the upper mold 5 is provided with an open riser 6; the lower mold 8 is provided with a lower mold fixing plate 10, and the lower mold The mold fixing plate 10 is fixedly connected with the lower mold 8 through the lower mold connecting rod 9, and an ejection system is provided under the ...

Embodiment 2

[0027] Such as Figure 1-2 As shown, the gravity casting mold of the end cover of the new energy water-cooled motor housing in Example 1 is used for casting, which specifically includes the following steps:

[0028] In the first step, the upper mold 5 and the lower mold 8 are subjected to surface sandblasting on the parts corresponding to the product forming surfaces;

[0029] In the second step, the upper mold 5 and the lower mold 8 are preheated to 290°C-300°C, and then the surface of the forming surface is sprayed with heat-insulating and high-heat-retaining paint;

[0030] The third step is to close the hydraulic core pulling 7 in place, close the upper mold 5 and the lower mold 8, heat the mold to 360°C-380°C, and then melt the natural gas aluminum melting furnace to obtain A356 aluminum liquid, aluminum liquid The temperature is controlled at 700°C-720°C, and the molten aluminum is poured directly into the sprue sleeve 3 of the mold through a scoop, and the molten alumi...

Abstract

The invention belongs to the technical field of new energy automobiles, in particular to a gravity casting mold for an end cover of a new energy water cooling motor shell and a casting process thereof. The mold comprises an upper mold and a lower mold. The upper mold and the lower mold are assembled to form mold cavity, a sprue is arranged at the center of the upper mold, sprue covers are arrangedaround the sprue, an ejecting system is arranged below the lower mold and comprises an ejector pin plate, an ejector pin panel, an ejector pin and a reset rod, a dividing cone is arranged at the center of the lower mold, the dividing cone and the sprue covers on the upper mold form a pouring gate with a slag avoiding function, a hydraulic pulling core is arranged on one side of the lower mold, and heating pipes are arranged on the upper and lower molds. The upper and lower molds are opened, the hydraulic pulling core is assembled in position to assemble the mold, and molten aluminum is castedin the mold cavity by a sprue casting mold. The mold is simple in structure, reasonable in design and high in yield. By additionally arranging the dividing cone, a product produced with the slag avoiding function is free of casting defects such as slag inclusion and pores. The mold is high in production efficiency and easy to operate and the labor intensity of staff can be ensured low.
