Magnetic element article injection mold

Abstract

The application relates to the technical field of injection mold structures, in particular to a magnetic element product injection mold, wherein the magnetic element product comprises a product and a positioning piece connected to the product, the magnetic element product injection mold comprises: a mold base comprising a base and a cover, the cover is arranged on the end of the base and surrounds the base to form a mold cavity, the mold cavity is used for accommodating the product, and the positioning piece is located outside the mold cavity and overlaps the end face of the end of the base to which the cover is arranged; wherein a gate for injecting thermoplastic plastic into the mold cavity is arranged on the base and / or the cover, a flash well is arranged on the inner wall of the mold cavity, the position of the flash well is opposite to the position of the gate, and the thermoplastic plastic injected into the mold cavity is first injected into the flash well. By arranging the flash well opposite to the gate, the impact force of the thermoplastic plastic on the product during injection and the shrinkage force of the product during cooling are weakened, so that the problem of fracture of the internal framework of the product during injection is solved.
