Abstract
The utility model relates to an automobile engine cover outer plate stamping die. The automobile engine cover outer plate stamping die comprises a male die and a female die. The shapes of the male die and the female die correspond to an automobile engine cover outer plate. A circle of blank holder is arranged outside the male die, the shapes of the male die and the blank holder correspond to the shape of the female die, and a layer of chrome coating is electroplated on molding faces of the male die, the female die and the blank holder. The automobile engine cover outer plate stamping die has the advantages that rigidity of the surface of the die is enhanced, sliding performance of the die and sheet materials is enhanced, and the phenomena such as galling and cracking caused by heating of the die in the process of stamping are reduced. Meanwhile, accuracy of the die can be maintained in the process of the stamping of the male die, the female die and the blank holder, and therefore, a stamping molding effect is good, production efficiency is improved, and the service life of the die is prolonged.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of diel that is electroplate with the automobile engine cover outside plate 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 automobile engine cover outside plate diel that is electroplate with hard chromium layer to solve the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
The diel of a kind of automobile engine cover outside plate, comprise punch and die, the shape of described punch and die is corresponding with automobile engine cover outside plate, 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 diel of above-mentioned a kind of automobile engine cover outside plate is characterized in that 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 automobile engine cover outside plate 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 cover outer plate, comprise punch 110 and die 210, the shape of punch 110 and die 210 is corresponding with automobile engine cover outside plate, 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 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.
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.
Claims (3)
