Abstract

The utility model discloses a multifunctional die structure. The multifunctional die structure comprises an upper die and a lower die, wherein the upper die is matched with the lower die, and concave-convex grooves are arranged in the upper die and the lower die. The shape of a product is formed by stretching the product to form a filleted corner by the male die, and a gap between a female die and the male die is two times larger than the thickness of the material. Compared with the prior art, the multifunctional die structure is capable of guaranteeing stable and reliable forming of the product and producing no undercut on the product, balanced in forming stretching, consistent in reduction amount, small in error and capable of pressing products with different thicknesses, so that demands of people are met.

Description

A kind of multifunctional mold structure

Technical field

The utility model relates to a kind of mould structure, is specifically related to a kind of multifunctional mold structure.

Background technology

Traditional mould structure moulding is due to complex-shaped, required precision is high, in process, slightly there is the error product just easily to produce undercut, and a kind of mould structure can only be suppressed a kind of product, and unstable product quality can not reach the multi-purpose function of a kind of mould structure, can not satisfy client's demand.

The utility model content

The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of multifunctional mold structure to be provided.

Technical scheme: a kind of multifunctional mold structure described in the utility model, comprise upper die and lower die, upper die and lower die are complementary, and are provided with tongue and groove between described upper die and lower die, and the gap between described die and punch is greater than the material thickness of 2 times.

As preferably, described multifunctional mold structure adopts hydraulic pressure or machine automatization mold-opening structure and ball guide pillar guide pin bushing.

Beneficial effect: the utility model can guarantee that formed product is reliable and stable, can not produce undercut to product, and the moulding stretching is balanced, attenuate amount uniform error is little, and can suppress the product of multi-thickness, has satisfied client's demand.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with specific embodiment:

As shown in Figure 1, a kind of multifunctional mold structure, comprise patrix 1 and counterdie 2, patrix 1 and counterdie 2 are complementary, and patrix 1 and counterdie 2 are provided with tongue and groove, and the shape of product is by the moulding of punch stretching fillet, the utility model can be suppressed the product of multi-thickness, the multifunctional mold structure adopts hydraulic pressure or machine automatization mold-opening structure and ball guide pillar guide pin bushing, guarantees that positioning accuracy is high, eliminated the gathering sill glade plane space, guarantees the crudy of plate.

Claims (1)

1. multifunctional mold structure, comprise patrix (1) and counterdie (2), patrix (1) and counterdie (2) are complementary, it is characterized in that: described patrix (1) and counterdie (2) are provided with tongue and groove, the shape of product is by the moulding of punch stretching fillet, and the gap between die and punch is greater than the material thickness of 2 times.
