Abstract

The utility model relates to a stamping mold of an automobile engine cover inner plate. The stamping mold of the automobile engine cover inner plate comprises a male mold and a female mold, wherein the shape of the male mold and the shape of the female mold correspond to the shape of the automobile engine cover inner plate, a blank holder is arranged on the outer side of the male mold, the shape of the male mold and the shape of the blank holder correspond to the shape of the female mold, molding faces of the male mold, the female mold and the blank holder are respectively provided with a hard chrome layer in plating mode, and a process supplement surface correspond to the blank holder of the male mold is arranged on the outer side of the female mold. The stamping mold of the automobile engine cover inner plate has the advantages of strengthening hardness of the mold surface and sliding performance of the mold and the plate, reducing galling, cracking and other phenomena caused by heating of the mold in the stamping process, enabling accuracy of the mold to be well maintained in stamping of an upper mold, a lower mold and the blank holder, enabling press forming effects to be good, improving production efficiency, and prolonging service life of the mold.

Description

A kind of diel of car engine cover inner panel

Technical field

The utility model relates to a kind of mould, particularly relates to a kind of diel that is electroplate with the car engine cover inner panel of hard chromium layer.

Background technology

Mould be on the industrial production in order to injection moulding, blowing, extrude, various moulds and instrument that the method such as die casting or forging forming, smelting, punching press, stretching obtains required product.In brief, mould is the instrument of formed article, and this instrument is made of various parts, and different moulds is made of different parts.It mainly realizes the processing of article profile by the change of institute's moulding material physical state.In the prior art, the product surface hardness of mould also has problems, and easily produces wearing and tearing.

The utility model content

The purpose of this utility model is in order to solve the existing defective of mould in the prior art, to provide a kind of diel that is electroplate with the car engine cover inner panel of hard chromium layer to solve the problems referred to above.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of diel of car engine cover inner panel, comprise punch and die, the shape of described punch and die is corresponding with automobile engine cover inner panel, the arranged outside of described punch has a circle blank holder, the shape of described punch and blank holder is corresponding with the shape of die, it is characterized in that, electroplate one deck hard chromium layer on the forming surface of punch, die and blank holder, the arranged outside of described die has the process complementary surface corresponding with the blank holder of punch.

The diel of above-mentioned a kind of car engine cover inner panel is characterized in that, the area of described die is identical with the area of the blank holder of punch.

The beneficial effect that the utlity model has: strengthened the sliding of hardness, enhancing mould and the sheet material of die surface, the phenomenons such as the minimizing plucking that the heating of mould causes in punching course, cracking occur.Simultaneously so that upper die and lower die and blank holder can better keep the accuracy of mould when punching press, thereby so that punch forming is effective, improved production efficiency, prolonged the mold use life-span.

Description of drawings

Fig. 1 is punch schematic diagram of the present utility model;

Fig. 2 is die schematic diagram of the present utility model.

The specific embodiment

Further understand and understanding for making architectural feature of the present utility model and the effect reached had, cooperate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:

Referring to Fig. 1 and Fig. 2, a kind of diel of automobile top-cap inner panel, comprise punch 110 and die 210, the shape of punch 110 and die 210 is corresponding with automobile engine cover inner panel, arranged outside at punch 110 has a circle blank holder 120, the shape of punch 110 and blank holder 120 is corresponding with the shape of die 210, and electroplates one deck hard chromium layer on the forming surface of punch 110, die 210 and blank holder 120.

In the arranged outside of die 210 process complementary surface 220 corresponding with the blank holder 120 of punch 110 arranged, the area of die 210 is identical with the area of the blank holder 120 of punch 110 simultaneously.

The beneficial effect that the utlity model has: strengthened the hardness of mould product face, simultaneously so that upper die and lower die in punching press, can point-devicely fit, thereby so that stamping forming effective.

In sum, it only is preferred embodiment of the present utility model, be not to limit the scope that the utility model is implemented, all equalizations of doing according to the described shape of the utility model claim scope, structure, feature and spirit change and modify, and all should be included in the claim scope of the present utility model.
