Injection molding equipment for lower shell of direct-current brushless motor and working method of injection molding equipment

Abstract

The invention discloses injection molding equipment for a lower casing of a direct-current brushless motor and a working method of the injection molding equipment. The equipment comprises a first casing, a lower die and an upper die are mounted at the inner side of the first casing, an injection molding hopper is fixedly mounted at the top of the first casing, and an air cylinder mounting plate isfixedly mounted at the end of an output rod of a movable air cylinder; a lifting air cylinder is fixedly mounted on the upper surface of the air cylinder mounting plate, a suction cup is fixedly mounted at the bottom end of an output rod of the lifting air cylinder, and a base is fixedly mounted at the top of the second shell; a top seat is fixedly mounted above the base, a scraping rod is movably mounted on the top seat along the vertical direction, the bottom end of the scraping rod is connected with the top seat in a penetrating manner, and a storage plate is fixedly mounted on the upper surface of the base. According to the injection molding equipment, the lower shell of the motor can be rapidly taken out and moved to the storage plate, the working efficiency is high, the deburring effect of the lower shell of the motor is guaranteed; the outer circumferential face and the inner circumferential face of a fixing column are polished through a steel brush, and the polishing effect isgood.

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 of producing industrial products. In the traditional motor lower casing, a fixed rod needs to be installed in the middle of the groove of the main body of the casing. If the welding method is adopted, the fixed rod is easy to break. In this case, the motor lower casing 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 cannot be kept s...

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;
