Embodiment Construction

[0014] Such as figure 1 As shown, the fine pressing mold for forming the automobile clutch cover consists of an upper mold base 1, a nitrogen spring cover plate 2, a nitrogen spring 3, an upper backing plate 4, a contour sleeve 5, an upper mold core 6, a press block backing plate 7, an upper Press block 8, guide 9, lower mold core insert 10, lower mold core 11, lower pressure block 12, lower discharge plate 13, lower mold core backing plate 14, lower mold base 15, middle hole positioning 16, etc. Among them, the upper mold core 6 can move up and down through the nitrogen spring 3, the nitrogen spring cover plate 2 is locked on the upper mold base 1 by screws, which is convenient for disassembly and assembly, and the contour sleeve 5 ensures that the upper mold core 6 is vertical when it goes down, and the lower mold core is inlaid Part 10 can be taken out separately, and its precision is guaranteed by surface grinding, which is more convenient for adjusting the depth of the co...

Abstract

An automobile clutch cover forming and pressing die, comprising an upper die base, a nitrogen gas spring, an upper backing plate, an upper die core, an upper pressing block, a lower die core, a lower pressing block, a lower discharge plate and a lower die holder, and is characterized by: : Also includes: a nitrogen gas spring cover, which is detachably connected to the upper die base, and the nitrogen gas spring is arranged between the upper die base and the nitrogen spring cover; an equal-height sleeve, the equal-height sleeve and the upper die core Connected, the upper mold core moves up and down through the nitrogen gas spring, and the upper mold core is controlled to maintain a vertical state when it goes down through the equal-height sleeve; the lower mold core insert is detachably connected to the lower mold core; The unloading plate is locked with the lower pressing block, and the up and down movement is realized by the hydraulic ejector rod to return the material. The advantage of the present invention is that: the upper die seat is equipped with a nitrogen spring cover, which can be directly twisted and taken out. In the lower core, the supporting ring surface is used as a separate insert, and it is smoothed by plane grinding to improve the flatness and surface roughness accuracy, and effectively ensure product performance.

Description

technical field [0001] The invention relates to the field of automobile clutch covers, in particular to an automobile clutch cover forming precision press mold for solving the problems of difficult disassembly and assembly of the mold, the flatness of the contact surface of the support ring, and convenient adjustment of the depth dimension of the cover. Background technique [0002] The existing automobile clutch forming mold does not have a nitrogen spring cover plate in the counterbore of the upper mold base. When installing the nitrogen spring, the upper mold core must be taken out before the nitrogen spring can be taken; the lower mold core is a whole, and the supporting ring surface can only be used For machining center milling, the flatness and surface roughness of milling are poor, which affects product performance. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide an automobile clut...
