The invention discloses an assembly product press-fitting die which enables the head of a bolt and a gasket to be subjected to press-fitting stress at the same time and effectively solves the press-fitting problem. The bottom face of the die handle is sunken to form a first pit, and a through first pin hole is formed in the side wall of the top of the first pit; a punch is inserted into the first pit; the punch is columnar, a second pin hole is formed in the surface of the top of the punch, and the pin shaft penetrates through the second pin hole to be fixedly connected with the first pin hole; and a circular first boss protrudes from the bottom surface of the punch. A movable punching die is also arranged. A first through hole is formed in the bottom surface of the movable punching die, the head of a bolt is inserted into the first through hole, the inner wall of the top of the first through hole protrudes to form an annular second boss, the punch penetrates through the first through hole, and the first boss and the second boss are connected in an overlapped mode. A spring is further included; and the punch is sleeved with the spring, and the spring is clamped between the die handle and the movable punching die. The die further comprises a female die, a second through hole is formed in the female die, the gasket is erected on the second through hole, and the bolt penetrates into the second through hole.
Description
technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a press-fitting mold for assembly products. Background technique [0002] Among the existing automotive fasteners, there is a type of component that is a combination of bolts and double-ear gaskets. This type of assembly is to press-fit the bolts and gaskets with interference. After the gaskets are pressed, the gaskets cannot rotate. turn torque. [0003] Gaskets and bolts must be connected together by interference press-fitting. The existing press-fitting mold is a press head installed on the die base of the punching machine. Often, the gaskets are deformed and warped on both sides under stress, which cannot meet the quality of the product. Require. Contents of the invention [0004] In view of the above shortcomings of the background technology, the purpose of the present invention is to provide a press-fitting mold for assembly products, which can simultaneously...
