Description

Technical Field

[0001] The utility model relates to the technical field of motor housing processing, in particular to a motor housing casting device. Background Art

[0002] The motor housing is an important component of the motor. Its main function is to protect the internal parts of the motor and prevent the intrusion of external factors such as dust and moisture. Currently, casting is a common processing method for motor housings. Its working principle is to inject liquid monomers or prepolymers into the mold under normal pressure, and then solidify and form a product with the same shape as the inner cavity of the mold after polymerization.

[0003] The traditional casting device lacks a heating structure at the discharge position, which causes the liquid raw material to cool and solidify easily, thereby causing blockage at the discharge position. At the same time, during casting, bubbles are easily generated when the liquid raw material flows, resulting in a decrease in the quality of the finished motor housing. Utility Model Content

[0004] To this end, the utility model provides a motor housing casting device to solve the above-mentioned problems in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] The connecting block is fixedly mounted on the outer side of the connecting frame close to one end of the lower mold.

[0010] Furthermore, the upper mold has discharge holes at equal intervals inside that are connected to the connection pipe.

[0011] Furthermore, a positioning rod inserted into the lower mold is fixedly installed in the middle of the lower end of the upper mold, and a prefabricated hole adapted to the positioning rod is opened inside the lower mold.

[0012] Furthermore, the longitudinal section of the mounting frame is an "F"-shaped structure, and a limiting groove is provided through the interior of the mounting frame.

[0013] Furthermore, the mounting frame and the connecting frame are arranged in a one-to-one correspondence, and the connecting frame forms a sliding structure with the mounting frame through a limiting groove.

[0014] Furthermore, the connecting blocks are in contact with the outer wall surfaces of the lower mold and the upper mold respectively, and the connecting blocks are symmetrically arranged with respect to the horizontal center axis of the connecting frame.

[0015] The utility model has the following advantages:

[0016] 1. Through the constant temperature plate, the constant temperature plate can heat the connecting pipe at a constant temperature to avoid the phenomenon of liquid raw materials cooling and solidifying in the connecting pipe;

[0017] 2.

There is a feed pipe 4, and the lower end of the feed pipe 4 is connected to a connecting pipe 5 located in the upper mold 2, and a constant temperature plate 7 is arranged on the outer side of the upper end of the connecting pipe 5. The upper mold 2 is provided with discharge holes 6 connected to the connecting pipe 5 at equal intervals. Before use, the feed pipe is fixedly connected to the feed pipe 4 through a flange, so that the liquid raw material is injected into the feed pipe 4, the connecting pipe 5 and the discharge hole 6 in sequence, and then injected into the lower mold 1 and the upper mold 2. At this time, the constant temperature plate 7 can heat the connecting pipe 5 at a constant temperature to avoid the liquid raw material from cooling and solidifying in the connecting pipe 5;
