Abstract

The utility model discloses a pressure casting trimming die structure which comprises an upper die base, an upper padding plate, an upper clamp plate, an upper stripper plate, a lower die base, a lower padding plate, a lower clamp plate and a lower stripper plate which are sequentially arranged. The upper die base, the upper padding plate and the upper clamp plate are fixedly connected, a guide pillar is arranged on the upper clamp plate, and the upper stripper plate is arranged outside the guide pillar in a penetrated mode and can slide upwards and downwards along the guide pillar. A product is formed between the upper stripper plate and the lower stripper plate in a pressure casting mode. A cut-off knife is arranged on the position, corresponding to the edge of the product, of the upper clamp plate, and is parallel to the guide pillar and is arranged in the upper stripper plate in a penetrated mode. According to the pressure casting trimming die structure, pressure casting edges are cut off by the adoption of the stamping principle, and compared with cutting in a traditional machine machining mode and manual cutting, the pressure casting trimming die structure has the advantages that the structure is dependable in quality, stable in production and low in cost, the punching and shearing section of the product is more flat, the production yield of the product is increased by 30%, the production is simple, and the machining stability is high, so that automatic production is more facilitated.

Description

Die casting shaving die structure

Technical field

The utility model relates to a kind of mould structure, relates in particular to a kind of die casting shaving die structure.

Background technology

Traditional die casting, after die cast, generally adopts machined or aritificial cut-off mode to carry out cutting of leftover pieces.But aritificial cut-off quality is uncontrollable, cause quality unstable, the inefficiency of aritificial cut-off simultaneously.Although tradition machining mode efficiency is high, processing cost is high, and machined stamping press is larger, often causes the punching end face out-of-flatness of product, even occurs internal fissure, damage product.

Summary of the invention

In order to overcome above-mentioned defect, the utility model provides a kind of die casting shaving die structure, and efficiency is high, and cost is low, stable and reliable product quality.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of die casting shaving die structure, comprise the upper bolster, upper padding plate, train wheel bridge, the up stripper that set gradually, and die shoe, lower bolster, lower plate and lower stripper, described upper bolster, upper padding plate and train wheel bridge are fixedly connected with, described train wheel bridge is provided with guide pillar, and described up stripper is arranged in this guide pillar outward and can slides up and down along this guide pillar; Product die cast is between described up stripper and lower stripper, and on described train wheel bridge, corresponding product marginal position place is fixed with cut-off knife, and this cut-off knife is parallel with described guide pillar and be arranged in described up stripper.

As preferred version of the present utility model, the upper bolster place plane of take is horizontal plane, the first side that cuts of described cut-off knife is that vertical plane and opposite side are an inclined plane, and this inclined plane and vertical plane intersect formation and cut sword, and the angle of this inclined plane and horizontal plane is 25-35 degree.

As preferred version of the present utility model, the angle of described inclined plane and horizontal plane is 30 degree.

The beneficial effects of the utility model are: this die casting shaving die structure is utilized punching press principle excision die casting material limit, with respect to traditional machining mode cut with aritificial cut-off have of fine qualities, produce stable, cost is lower, the punching section of product is more smooth, production Yield lmproved reaches 30%, procedure for producing is simple, processing stability advantages of higher, thus be more conducive to automated production.

Fig. 1 is the utility model structural representation;

Fig. 2 is the cutting head structural representation of cut-off knife described in the utility model.

By reference to the accompanying drawings, make the following instructions:

11---upper bolster 12---upper padding plate

13---train wheel bridge 14---up stripper

15---guide pillar 21---die shoe

22---lower bolster 23---lower plate

24---lower stripper 30---product

40---cut-off knife 41---vertical plane

42---inclined planes 43---cut sword

50---horizontal plane

The specific embodiment

Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is elaborated.But protection domain of the present utility model is not limited to following embodiment, the simple equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.

As shown in Figure 1, a kind of die casting shaving die structure, comprise the upper bolster 11, upper padding plate 12, train wheel bridge 13, the up stripper 14 that set gradually, and die shoe 21, lower bolster 22, lower plate 23 and lower stripper 24, described upper bolster, upper padding plate and train wheel bridge are fixedly connected with, described train wheel bridge is provided with guide pillar 15, and described up stripper is arranged in this guide pillar outward and can slides up and down along this guide pillar; Product 30 die casts are between described up stripper and lower stripper, and on described train wheel bridge, corresponding product marginal position place is fixed with cut-off knife 40, and this cut-off knife is parallel with described guide pillar and be arranged in described up stripper.

Take upper bolster place plane as horizontal plane 50, and the first side that cuts of described cut-off knife is that vertical plane 41 and opposite side are an inclined plane 42, and this inclined plane and vertical plane intersect to form and to cut sword 43, and the angle of this inclined plane and horizontal plane is 25-35 degree, is preferably 30 degree.

During product die cast, by train wheel bridge, drive cut-off knife to realize cutting of product rim charge, efficiency promotes greatly.While cutting; because cut-off knife forms triangle cutting head; cutting sword 43 first touches product product is cut; then cut-off knife progressively deeply cuts down to completing, and can not cut position to product and cause extruding, thereby the section forming is very smooth; section more there will not be crackle; better protect product, promoted product quality, reduced product fraction defective.
