Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor manufacturing technology, specifically a die-casting device for DC motor production. Background Technology
[0002] A DC motor is a rotating electric motor that can convert DC electrical energy into mechanical energy (DC motor) or mechanical energy into DC electrical energy (DC generator). The motor requires the use of magnets, which are usually produced by die casting.
[0003] Publication No. CN220342195U discloses a rapid production device for DC motor magnetic tiles. The device includes a cleaning mechanism comprising a drive motor, which is fixedly connected to the left side of the inner wall of an intermediate housing. A lead screw is fixedly connected to the output end of the drive motor, and the end of the lead screw away from the drive motor is rotatably connected to the right side of the inner wall of the intermediate housing. After the upper mold die-casting is completed, the cleaning mechanism is activated, causing a cleaning roller to move below the upper mold, thereby cleaning the residual magnetic tile production material at the bottom of the upper mold. This prevents unevenness on the top of the subsequently produced magnetic tiles, improving the practicality of the device. However, this patent still has the following problems in actual use: Although this DC motor magnetic tile rapid production device cleans the residual magnetic tile production material at the bottom of the upper template by moving the cleaning roller below the upper template, the upper template is concave, making it impossible for the surface of the cleaning roller to adhere to the surface of the upper template during cleaning, thus affecting the cleaning effect. At the same time, the magnetic material is not collected during the cleaning roller cleaning process, causing the magnetic material to fly around randomly as the cleaning roller rotates, which is not conducive to the collection of magnetic material.
[0004] Therefore, a die-casting device for DC motor production is proposed to solve the problems mentioned above. Utility Model Content

At the same time, the magnetic material is not collected during cleaning of the cleaning roller, causing the magnetic material to fly around randomly as the cleaning roller rotates, which is not conducive to the collection of magnetic material.
