Abstract

The utility model relates to a stamping mold of an automobile left front door outer plate and a right front door outer plate. The stamping mold of the automobile left front door outer plate and the right front door outer plate comprises a male mold and a female mold, wherein the male mold and the female mold both comprise a left male mold and a left female mold which correspond to the automobile left front door outer plate and a right male mold and a right female mold which correspond to the right front door outer plate, the outer side of the left male mold and the outer side of the right male mold are respectively provided with a blank holder, the shape of the male mold and the shapes of the blank holders correspond to the shape of the female mold, forming surfaces of the male mold, the female mold and the blank holders are respectively provided with a hard chrome layer in plating mode. The stamping mold of the automobile left front door outer plate and the right front door outer 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 holders, enabling press forming effects to be good, improving production efficiency, and prolonging service life of the mold.

Description

The diel of external door panel before a kind of vehicle right and left

Technical field

The utility model relates to a kind of mould, particularly relates to a kind of diel that is electroplate with the front external door panel of vehicle right and left 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 produces easily 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 front external door panel of vehicle right and left 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:

The diel of external door panel before a kind of vehicle right and left, comprise punch and die, described punch and die include the left punch corresponding with the left front door outside plate and left die, right punch and the right die corresponding with the right front door outside plate, the arranged outside of described left punch and right 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 external door panel is characterized in that the arranged outside of described left die and right die has the process complementary surface corresponding with the blank holder of left punch and right punch before above-mentioned a kind of vehicle right and left.

The diel of external door panel is characterized in that the area of described die is identical with the area of the blank holder of punch before above-mentioned a kind of vehicle right and left.

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.

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 vehicle right and left beater or beat-up outside plate, comprise punch 110 and die 210, punch 100 and die 200 include the left punch 111 corresponding with the automobile left front door outside plate and left die 211, with Automobile Right before corresponding right punch 112 and the right die 212 of external door panel, the arranged outside of left punch 111 and right punch 112 has a circle blank holder 120, the shape of punch 110 and blank holder 120 is corresponding with the shape of die 210, electroplates one deck hard chromium layer on the forming surface of punch 110, die 210 and blank holder 120.

The arranged outside of left die 211 and right die 212 has the process complementary surface 220 corresponding with the blank holder 120 of left punch 111 and right punch 112.And the area of die 210 is identical with the area of the blank holder 120 of punch 110.

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.
