Technical Field
[0001] This utility model relates to the field of shell molding technology, specifically a Hall sensor shell molding equipment. Background Technology
[0002] Hall sensors are magnetic field sensors based on the Hall effect. In the production of plastic housings for sensors, injection molds are required. Injection molds are tools for producing plastic products, giving them a complete structure and precise dimensions. Specifically, they involve injecting molten plastic into a mold cavity under high pressure using an injection molding machine, and then cooling and solidifying it to obtain the molded product.
