Reasonable tooling design can ensure that the product processing quality meets the requirements.
[0003] The design of a certain transformer product requires the use of thermosetting resin for injection molding in the tooling. The transformer device body is relatively small in size, and a curved bracket is used to fix the body in the left and right directions. Since the bracket material is relatively thin, when the transformer product is loaded into the tooling, the bracket is offset and not centered. At the same time, since the left and right injection molding margins of the transformer product are relatively small, when the bracket is offset and not centered, the thickness of the injection molding material will be uneven on the left and right sides of the product.
