Description

Technical Field

[0001] The invention relates to the technical field of cleaning injection molded products, in particular to an injection mold with a motor magnet block gasket capable of cleaning burrs. Background Art

[0002] Motor magnet block gasket is a thin sheet material placed between the magnet block and the surrounding structure. Its main function is to ensure uniform gap between the magnet block and adjacent components to optimize magnetic field distribution and motor performance, absorb some vibration and noise to improve the running stability and service life of the motor, and prevent current from passing between the magnet block and other metal parts to protect the safety of the motor circuit. There are many kinds of materials for motor magnet block gaskets, including rubber materials, plastic materials, metal materials, and magnetic materials. Brushless motor refers to a DC motor that does not use mechanical brush commutation. It uses an electronic commutator instead of a brush. Traditional mechanical commutator and brushes are used to realize the conversion of electrical energy into mechanical energy; after the production of some brushless motor magnet block rotors, it is necessary to use an injection molding machine to injection mold the gasket to the upper and lower end surfaces of the magnet block rotor; during production, the magnet block rotor is placed in the lower mold, and then the lower mold is moved to the bottom of the upper mold, the upper mold is moved down and combined with the lower mold and pressed tightly, and the injection molding machine injects the heated and molten material into the upper and lower molds through the flow channel, and after the injection molding material is solidified, the gasket is connected to the upper and lower end surfaces of the magnet block rotor, and finally the magnet block rotor and the gasket are ejected to complete demolding and taking out the parts.

[0003] After the gasket is injection molded and connected to the magnet block rotor using an injection molding machine, the temperature of the newly formed gasket is relatively high, and a portion of the material in the flow channel of the injection molding mold will remain connected to the inside of the gasket. The subsequent work such as removing the residual material and cleaning the burrs is mostly done manually, and the efficiency and quality cannot be guaranteed. For this reason, we propose an injection mold for a motor magnet block gasket that can clean the burrs. Summary of the invention

[0056] When in use, the horizontal push rod 62 is started, driving the bracket 61 to slide on the injection molding machine body 1, and the vertical push rod 64 is started, driving the slide seat 63, two connecting plates 65, and two ring seats 66 to slide on the bracket 61.

[0058] After the electromagnet 113 absorbs the motor magnet block, it moves upward, and the gasket on the motor magnet block gradually approaches the air guide tube 142. The air guide tube 142 contacts and pushes the residual material at the connection of the gasket injection channel. During the continued upward movement, the residual material is continuously pushed away from the gasket and falls from the middle of the motor magnet block; then the wind generated by the rotation of the fan 7 is blown out obliquely downward from the multiple air outlets 143 on the air guide tube 142, first cooling the gasket with air; then the limit motor 153 is used to control the two grinding rods 8 to synchronously move in the opposite direction to expand the distance, so that the two grinding rods 8 contact the connection of the gasket injection channel, and then the power motor 132 is used to control the two grinding rods 8 to rotate synchronously, and the two grinding rods 8 clean the burrs at the connection of the gasket injection channel.
