Abstract

The utility model discloses an anti-deformation raising mold which comprises an upper mold and a lower mold. The upper mold comprises an upper mold seat, an upper base plate and an upper mold plate which are sequentially arranged. The lower mold comprises a stripper plate, a lower mold plate, a lower base plate and a lower mold seat. A groove is formed in the lower mold plate, and the upper mold plate is clamped with the groove during mold closing. By forming the groove which can be clamped with the upper mold plate in the lower mold plate, during the mold closing, the upper mold plate presses blank into the lower mold plate. Through the matching with the groove, bends are formed all around a product. Through the limiting of the bends and the groove, irregular flow of materials during a raising process is avoided, and therefore warping and twisting during the raising process do not exist, and product quality is effectively guaranteed.

Description

Anti-deformation raising mould

Technical field

The utility model belongs to cold stamping shaped technical field, particularly a kind of anti-deformation raising mould.

Background technology

In the actual production process, the problem on deformation that exists during the raising product shaping is difficult to overcome, and uses various way in the raising mould of raising product shaping is made, and effect also is not quite similar, but effect is all undesirable.Because being irregular the flowing of material in forming process, the main cause of raising distortion causes, therefore, want to solve the problem on deformation of raising product, just must solve the flow field problem of material, namely how avoid the flow deformation of material in the raising process, becoming needs the problem that solves.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of anti-deformation raising mould, causes deformation of products to avoid producing flowing of material in the raising process.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of anti-deformation raising mould, comprise patrix and counterdie, described patrix comprises upper bolster, upper padding plate and the cope match-plate pattern that sets gradually, described counterdie comprises stripper plate, lower bolster, lower bolster and the die shoe of setting, described lower bolster is provided with groove, and described cope match-plate pattern engages with described groove during mold closing.

Preferably, during mold closing the gap between described cope match-plate pattern and the lower bolster greater than the thickness of product.

Preferably, described stripper plate places in the described groove, and described stripper plate contacts with lower bolster during mold closing.

Pass through technique scheme, the anti-deformation raising mould that the utility model provides, its groove by engaging with cope match-plate pattern lower bolster setting, when mold closing, cope match-plate pattern with the blank punching press to lower bolster, and by around product, forming bending with cooperating of groove, spacing by bending and groove, thereby the irregular of material flowed when having prevented raising, thereby produces warpage and distortion when not having raising, and product quality obtains effective guarantee.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.

According to Fig. 1 and 2, the anti-deformation raising mould that the utility model provides, comprise patrix and counterdie, patrix comprises upper bolster 11, upper padding plate 15 and the cope match-plate pattern 12 that sets gradually, counterdie comprises stripper plate 16, lower bolster 13, lower bolster 17 and the die shoe 14 of setting, lower bolster 13 is provided with groove, and cope match-plate pattern 12 engages with groove during mold closing.Such as Fig. 2, during mold closing, the gap between cope match-plate pattern 12 and the lower bolster 13 is slightly larger than the thickness of product to guarantee normal mold closing and to prevent deformation of products; In addition, stripper plate 16 is to place in the groove, and stripper plate 16 contacts with lower bolster 17 during mold closing.

The anti-deformation raising mould that the utility model provides, it is by arranging the groove that can engage with cope match-plate pattern 12 at lower bolster 13, when mold closing, cope match-plate pattern 12 with blank shown in Figure 1 18 punching presses to lower bolster 13 interior formation finished product 21 shown in Figure 2, and by around product, form bending with cooperating of groove, spacing by bending and groove, thereby the irregular of material flowed when having prevented raising, thereby producing warpage and distortion when not having raising, product quality obtains effective guarantee.

Multiple modification to above-described embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, in other embodiments realization.

Claims

1. anti-deformation raising mould, comprise patrix and counterdie, described patrix comprises upper bolster, upper padding plate and the cope match-plate pattern that sets gradually, described counterdie comprises stripper plate, lower bolster, lower bolster and the die shoe of setting, it is characterized in that, described lower bolster is provided with groove, and described cope match-plate pattern engages with described groove during mold closing.

2. anti-deformation raising mould according to claim 1 is characterized in that, the gap during mold closing between described cope match-plate pattern and the lower bolster is greater than the thickness of product.
