[0002] With increasingly stringent national environmental protection requirements, electric vehicles are developing at a rapid pace. Components in electric vehicles, such as batteries, motors, motor controllers, and chargers, generate a significant amount of heat during operation. Accumulated heat can lead to component failure and even spontaneous combustion.
[0003] Therefore, electric vehicles must be designed with a cooling system to cool the relevant components. However, since electric vehicles have eliminated the traditional internal combustion engine, they cannot rely on mechanical water pumps for cooling. Against this background, automotive electronic water pumps have emerged.
[0004] The existing molds for manufacturing the casing of electronic water pumps have fixed dimensions for the outlet and inlet each time they are made, which cannot adapt to different size requirements and has poor versatility.

[0013] The end of the second insert near the third insert extends out of the first fixing member through the through hole from the groove and connects with the third insert. The limiting step abuts against the inner wall of the groove.
[0014] As a preferred embodiment, a positioning protrusion is provided on the upper end surface of the lower mold core, and a positioning groove is recessed on the first fixing member. The first fixing member is connected to the lower mold core, and the positioning protrusion is adapted to the positioning groove.
[0015] As a preferred embodiment, the lower end face of the lower mold core is recessed with a mounting groove, the first fixing member is installed in the mounting groove, and the inner bottom wall of the mounting groove forms a positioning protrusion.
[0016] As a preferred embodiment, a stop block is installed in the mounting groove, and the end of the first fixing member near the third insert abuts against the stop block.

The second fixing member is located above the first fixing member and connected to the upper part of the first fixing member, and the upper end face of the first fixing member abuts against the second fixing member.
[0018] As a preferred embodiment, the second fixing member is detachably connected to the upper end face of the lower mold core.
[0019] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, it mainly uses a detachable first insert and a second insert, which can achieve different sizes of inlet and outlet by replacing different inserts, and has good versatility.
[0020] Secondly, the combination of positioning protrusions and positioning grooves facilitates the quick installation of the first fixing component, while the combination of stop blocks and second fixing components ensures the stability and reliability of the second insert during the injection molding process.
