Embodiment

[0039] The specific embodiment of the present invention is as Figure 1-5As shown, a molding die for an automobile engine cover outer panel includes an upper mold base 1 and a lower mold base 2 . The upper surface of the lower mold base 2 is provided with a pulley 3 that can move horizontally forward. This tackle 3 becomes inverted " product " font, and both sides are all provided with guide sliding surface, are placed in the concave cavity of lower mold base 1 and move. The upper surface of the front end of the tackle 3 is provided with a front end molding 32 . Above both side edges of the tackle 3 are all provided with side edge moldings 4 that rise as the tackle 3 advances. The edge of the tackle 3 between the front end forming part 32 and the side forming part 4 is connected with a hypotenuse slider mounting seat 34, and the upper surface of the hypotenuse slider mounting seat 34 is provided with a hypotenuse molding that can move horizontally away from the side of the t...

Abstract

The invention discloses an automobile engine cover outer plate forming die, relates to the field of engine cover outer plate production, and is mainly used for solving the problem that an existing tackle can only drive one sliding block or drive two sliding blocks. According to the main structure, the forming die comprises an upper die base and a lower die base; a tackle is arranged on the upper surface of the lower die base; a front end forming piece is arranged on the upper surface of the front end of the tackle; side edge forming pieces are arranged above the edges of the two sides of the tackle; and the edges, between the front end forming piece and the side edge forming pieces, of the tackle are connected with bevel edge sliding block mounting seats; and a bevel edge forming piece is arranged on the upper surface of each bevel edge sliding block mounting seat. According to the automobile engine cover outer plate forming die, the die can drive all the forming pieces through one tackle, so that the flanging forming procedure of an engine cover outer plate can be completed by only one step, and meanwhile, the situation that the structure of the die is too complex is avoided.

Description

technical field [0001] The invention relates to the field of engine cover outer plate production, in particular to an automobile engine cover outer plate forming die. Background technique [0002] The engine cover outer panel is one of the most important outer covers on the car, and it is also a key part that affects the appearance quality of the whole car. It is located above the front of the car, and it is mostly a steel plate part, which is stamped by a mold through several processes. Since the shape of the outer panel of the engine cover is relatively regular, and the curvature requirements of the curved surface are relatively high, the quality of the outer panel of the engine cover can more intuitively reflect the technology and manufacturing level, and it is considered to be a typical part of the outer cover of the car. [0003] For the production of the outer panel of the engine cover, it is mainly completed by extruding the sheet through the forming die—that is, pla...
