Mechanical mechanism for delayed release of upper die core of drawing die

Abstract

The invention provides a mechanical mechanism for delayed release of an upper die core of a drawing die. The mechanical mechanism comprises delay units (3). The delay units (3) comprise supporting rollers capable of horizontally reciprocating and rotary supporting blocks abutting against the supporting rollers. Supporting boxes are distributed on a lower die holder (4) at equal intervals, the supporting rollers (32) are arranged in the supporting boxes, the rotary supporting blocks (31) are hinged to the peripheral side of a blank holder (2), the peripheral side of the upper die core (1) extends downwards to form protruding blocks (11), and when the die is closed, the lower surfaces of the protruding blocks (11) abut against the upper surfaces of the rotary supporting blocks (31). According to the mechanical mechanism for delayed release of the upper die core of the drawing die, the mode that the rotary supporting blocks and the protruding blocks are matched with each other is adopted, it is guaranteed that the upper die core cannot be released immediately after die opening, the effect of delayed release is achieved, the machining quality of parts is guaranteed, waste products are avoided, and good economical efficiency is achieved.

Description

technical field [0001] The invention belongs to the field of mold processing, and in particular relates to a mechanical mechanism for delayed release of a mold core on a drawing mold. Background technique [0002] In automobile production, many parts need to be processed by molds, and drawing dies are a very important step. During the mold opening process of the drawing die, the upper mold core will be released with the lifting process of the upper mold. When the mold core is released, the blank holder is lifted at this time, which will deform the parts and even produce waste products, which greatly damages the company's economic benefits. Contents of the invention [0003] In view of this, the present invention aims to propose a mechanical mechanism for delaying the release of the upper core of the drawing die, so as to delay the release time of the upper core after the mold is opened and ensure the processing quality of the parts. [0004] In order to achieve the above...

Problems solved by technology

During the mold opening process of the drawing die, the upper mold core will be released with the lifting process of the upper mold. When the mold core is released, the blank holder ring will be lifted at this time, which will deform the parts and even produce waste products, which will greatly damage the company's economic benefits
