Injection molding equipment for lower case of DC brushless motor and working method thereof

Abstract

The invention discloses an injection molding device for the lower casing of a DC brushless motor and a working method thereof. The device includes a first casing, a lower mold and a lower mold are installed on the inner side of the first casing, The top is fixed with an injection plastic bucket, the end of the output rod of the moving cylinder is fixed with a cylinder mounting plate, the upper surface of the cylinder mounting plate is fixed with a lifting cylinder, and the bottom of the output rod of the lifting cylinder is fixed with a suction cup. The top of the body is fixedly installed with a base, the top of the base is fixedly installed with a top seat, and a scraper rod is installed on the top seat movable along the vertical direction. ;This injection molding equipment can quickly take out the lower casing of the motor and move it to the storage plate. It has high work efficiency and ensures the deburring effect of the lower casing of the motor. The outer and inner peripheral surfaces of the fixed column are polished by steel brushes. , good polishing effect.

Description

technical field [0001] The invention relates to the technical field of motor processing equipment, in particular to an injection molding equipment used for the lower casing of a DC brushless motor and a working method thereof. Background technique [0002] Injection molding is a method for the production of industrial products. In the traditional motor lower case, a fixed rod needs to be installed in the middle of the groove of the main body of the case. If the traditional welding method is used, the fixed rod is easy to break. In this case, the motor lower case is in the middle of the groove. The fixed column can be formed at one time during the injection molding process, and the fixed column can be installed in the round hole of the fixed column, which can ensure the service life of the fixed column; the motor lower casing needs to be manually removed after the injection molding is completed, which is labor-intensive and low-efficiency. , The lower casing of the motor cann...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a kind of injection molding equipment and its working method for the lower casing of the DC brushless motor. In the present invention, the injection molding solution is added into the injection plastic hopper, and the injection molding solution enters the space between the upper mold and the lower mold through a conduit. In the injection molding cavity, after the injection molding solution cools down, the injection molding solution solidifies in the injection molding cavity and forms the lower casing of the motor. The upper mold is driven up by the upper mold cylinder, and the suction cup is moved by the moving cylinder, so that the suction cup moves to the top of the motor lower casing. The suction cup is driven down by the lifting cylinder so that the bottom of the suction cup is in contact with the top of the lower casing of the motor, and the lower casing of the motor is held by the suction cup. The lifting cylinder drives the lower casing of the motor to separate from the upper mold, and the moving cylinder drives the lower casing of the motor to move to the top seat and Between the bases, the suction cup loosens the motor lower casing, and puts the motor lower casing into the storage slot of the storage board. The invention can quickly take out the motor lower casing and move it to the storage board, which solves the problem of the traditional motor lower casing After the injection molding is completed, it needs to be taken out manually, which is a technical problem of high labor intensity and low work efficiency;
