High-temperature-resistant copper bar injection mold and process for three-electric product of new energy automobile

Abstract

The high-temperature-resistant copper bar injection mold comprises a first upper mold body and a lower mold body, a first inserting hole is formed in the middle of the first upper mold body, a second upper mold body is inserted into the inserting hole, a second inserting hole is formed in the center of the second upper mold body, and a clamp used for clamping a copper bar is inserted into the second inserting hole; an injection mold cavity is formed among the first upper mold, the second upper mold, the lower mold and the clamp, a first sliding block and a second sliding block which are inserted from a splicing face are arranged on the two sides of the first upper mold and the two sides of the lower mold, a first inserting plate which is inserted into the mold cavity and abuts against a copper bar is arranged at the end of the first sliding block, and a second inserting plate which is inserted into the mold cavity and abuts against the copper bar is arranged at the end of the second sliding block. The first inserting plate and the second inserting plate are symmetrically arranged on the two sides of the copper bar and divide the mold cavity into an upper half part and a lower half part, the mold further comprises a third sliding block and a fourth sliding block which replace the first sliding block and the second sliding block, no inserting plate is arranged at the end of the third sliding block and the end of the fourth sliding block, and the manufactured copper bar injection molding part permanently solves the leakage risk of a product.

Description

technical field [0001] The invention relates to the technical field of copper bar injection molding, in particular to a copper bar injection mold and a process. Background technique [0002] At present, the conductive connection copper bars on the market are mostly single-insert injection molding structures. This structure meets the requirements for electrical products without sealing requirements. The tightness between the upper and lower halves of the row, that is, the inner and outer structure of the injection-molded copper row, the two ends of the copper row are connected to the motor and the electronic controller respectively, the motor is in a sealed sealed cavity, and the cavity has power supply The oil cooled by the machine, the electronic control part has IGBT modules, PCB boards and capacitors and other devices, which cannot be in contact with the liquid). The sealing outside the injection molding structure of the insert is easy to ensure, but due to the single met...
