Trial-produced die for outer plate of engine cover

Abstract

The invention discloses a trial-produced die for an outer plate of an engine cover. The trial-produced die comprises a drawing process module and a flanging process module. The drawing process modulecomprises a drawing male die, an edge pressing ring and a drawing female die. The drawing male die is fixed to a pressing machine lower working table. The drawing female die is fixed to a pressing machine upper working table and comprises a female die ring, a female die core, a first support block and a second support block. The flanging process module comprises a flanging male die and a flangingfemale die. The flanging male die is fixed to a machine tool upper working table. The flanging female die comprises a female die ring and a female die core and is fixed to the pressing machine lower working table. According to the trail-produced die for the outer plate of the engine cover, dies are shared for drawing and flanging, elastic elements do not exist, and therefore the trial-production cost is reduced, the cost of trial-production dies is reduced, casting pollution is reduced, the mounting and debugging difficulty of the die is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of trial-manufacture molds for outer panels, in particular to a trial-manufacture mold for engine hood outer panels. Background technique [0002] With the increasing competition in the domestic auto industry, the development cycle of domestic auto products is getting shorter and shorter, and there are more and more multi-platform, multi-variety, and multi-project parallel trial production work, and the competition is becoming more and more fierce. Important status, even related to the success or failure of the entire project. Soft film development and soft film sample production are an important part of the trial production of prototypes. How to save the cost of soft film casting and improve the efficiency of trial production has become an important issue in the development of trial soft film. [0003] Existing hood parts usually use a common mold for drawing and flanging. At least one of the punch and die...

Problems solved by technology

[0003] Existing hood parts usually use a shared mold for drawing and flanging. At least one of the punch and die is driven by a drive unit to perform reciprocating motion for opening and closing. The bottom of the die is equipped with a nitrogen spring. There are detachable inserts on the edge, the inserts are installed on the punch when drawing, and
