Abstract

The utility model belongs to the technical field of the automobile panel preparation, especially relate to a mould and insert block structure on type of drawing mould. Insert including last mould base member and upper die base, the upper die base is inserted to insert including the upper die base that is located part beyond the blank holder and I is inserted II with the upper die base that is located part within the die parting line to the upper die base is inserted and I is adopted cr12MoV ( cold work die steel ) material to make, and the upper die base is inserted and II is adopted GM246 cast steel materials to make. The utility model discloses mould and insert block structure on type of drawing mould is simple, equitable, and easy to carry out on the basis of guaranteeing the die life, can show reduction die cost, consequently, is suitable for very much to promote and implements.

Description

A kind of drawing die patrix and insert structure

Technical field

The utility model belongs to automobile panel manufacture technology field, particularly relates to a kind of drawing die patrix and insert structure.

Background technology

Due to the requirement of automotive light weight technology, automobile panel high-strength plate material gets more and more, and concerning mould drawing sequence, only has the material good with anti-wear performance, hardness is high to extend die life.The material that anti-wear performance is good, hardness is high is adopted then will inevitably greatly to increase Mold Making cost.In addition, the main stress area of drawing die and walk to expect region mainly part beyond blank holder is all higher to the wearability of mold material, hardness requirement.Then require relatively low for the material of part within die parting line.

Summary of the invention

The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly, and provides a kind of structure simple, easy to implement, on the basis ensureing die life, can reduce drawing die patrix and the insert structure of die cost.

For solving the problems of the technologies described above, the technical solution of the utility model is:

Design a kind of drawing die patrix and insert structure, comprise mold matrix and upper bolster insert, described upper bolster insert comprises the upper bolster insert I that to be positioned at beyond blank holder part and the upper bolster insert II of part within being positioned at die parting line, and upper bolster insert I adopts Cr12MoV(cold work die steel) material makes, and upper bolster insert II adopts GM246 cast steel to make.

Described mold matrix adopts HT300 material to make.

The beneficial effect of technical solutions of the utility model is:

1, structurally, upper bolster insert design is Split type structure by the utility model drawing die patrix and insert structure, and for the main stress area of drawing die and walk to expect region mainly beyond blank holder the upper bolster insert I of part adopt the insert of Cr12MoV cold work die steel material, and the upper bolster insert II of part adopts GM246 cast steel within die parting line, thus on the basis ensureing die life, significantly reduce Mold Making cost.

2, structurally, mold matrix contained by the utility model adopts HT300 material to make, then further, on the basis ensureing die life, reduce Mold Making cost.In addition, overall structure is simple, is easy to processing and fabricating.

3, to sum up, the utility model drawing die patrix and insert structure are simply, rationally, easy to implement, on the basis ensureing die life, significantly can reduce die cost, therefore, be very suitable for promotion and implementation.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:

Fig. 1 is the perspective view of the utility model drawing die patrix and insert structure;

Sequence number in figure: 1, upper bolster matrix, 2, upper bolster insert I, 3, upper bolster insert II.

Detailed description of the invention

Embodiment one:

See in Fig. 1, figure, the utility model drawing die patrix and insert structure, comprise mold matrix and upper bolster insert, and wherein upper bolster insert comprises upper bolster insert I and upper bolster insert II.For the main stress area of drawing die and walk to expect region mainly part beyond blank holder, higher to the wearability of mold material, hardness requirement, Cr12MoV cold work die steel is adopted (to be the Chinese Industrial Standards (CIS) trade mark to the upper bolster insert I of installing herein, the standard brand of the Japan corresponding to it is SKD11) insert of material, and the material of part requires relatively low within die parting line, adopt GM246 cast steel to the upper bolster insert II of installing herein, die holder matrix adopts the version of HT300 cast iron.Thus, on the basis ensureing die life, reduce die cost.

The foregoing is only the schematic detailed description of the invention of the utility model; and be not used to limit scope of the present utility model; the equivalent variations that any those skilled in the art makes under the prerequisite not departing from the utility model design and principle and amendment, all should belong to the scope of the utility model protection.

Claims (2)
