Description

Technical Field

[0001] The invention relates to the technical field of casting equipment, in particular to a casting equipment for manufacturing a Y-type water pump housing. Background Art

[0002] A water pump is a machine that transports liquid or pressurizes liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the liquid energy. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals, etc. Existing water pumps can transport water.

[0003] With the development of science and technology, the shape of water pumps has changed, including a Y-shaped water pump. For example, "a multi-waterway intelligent output water pump" (CN202010495318.7) is disclosed in the Chinese Patent Network. In the production process of the water pump, the outer shell needs to be made first, and the injection molding equipment is used in the production process of the outer shell.

[0004] In the process of casting the pump body, the traditional process adopts the method of horizontal pouring, and the specific operation is: first, prepare two upper and lower mold plates distributed up and down, and place sand cores in the upper and lower mold plates. The upper and lower mold plates and the sand cores together form a horizontally distributed water pump body cavity, and then start pouring to form a pump body casting.

[0005] There are certain defects in this casting process: due to the structural characteristics of the pump body itself, its surface has a number of annularly distributed reinforcing ribs, and these ribs are higher than the upper surface of the pump body when the pump body is placed horizontally, and the thickness of the ribs themselves is not too thick. Therefore, based on the above situation, when the horizontal casting is carried out, this part of the ribs will be unstable during molding and the structural strength cannot be guaranteed.

[0038] During operation, the Y-shaped module 3 is first placed in the Y-shaped groove 23 of the left clamp 21, and one end of the limit column 4 is placed in the second hole 26. After the two clamps 21 are brought close together, the limit column 4 is conveniently inserted into the first hole 26 through the arc surface 253.
