Abstract

A leather film forming die used in a vacuum booster comprises an upper die plate, a lower die plate, and a middle die plate between the upper die plate and the lower die plate, wherein, an upper die plate side opening is formed on the upper die plate. The leather film forming die used in the vacuum booster has the benefits as follows: by additionally arranging the middle die plate, a product can be demoulded easily, the probability of tearing is low, and the yield is improved; and by adopting a novel processing manner of forming the upper die plate side opening, high standard requirements of customers can be met.

Description

A kind of vacuum booster epithelium mould

Technical field

The utility model relates to the mould class, relates in particular to a kind of vacuum booster epithelium mould.

Background technology

Traditional vacuum booster generally is made up of upper die plate, cope match-plate pattern, lower bolster, counterdie backing plate with the epithelium mould, but be difficult for making product to deviate from smoothly built on the sand owing to being connected between cope match-plate pattern and the lower bolster, also exist the possibility that product is torn easily; In addition, its structure has been subjected to very big influence aspect process technology, cause product glossiness relatively poor, can't satisfy client's high standard requirement.

The utility model content

At above defective, the purpose of this utility model provides a kind of vacuum booster epithelium mould, by template in setting up and cooperate the processing mode of patrix side opening, thereby reaches the purpose of further raising product percent of pass.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of vacuum booster epithelium mould comprises cope match-plate pattern and lower bolster, accompanies middle template between described cope match-plate pattern and the lower bolster, offers the patrix side opening on the described cope match-plate pattern.

Vacuum booster described in the utility model with the beneficial effect of epithelium mould is: in configuration aspects, by setting up middle template, make product be easy to the demoulding and be difficult for tearing, improved yield rate; By being improved to the novel processing mode of patrix side opening, can reach client's high standard requirement.

Description of drawings

According to embodiment and accompanying drawing the utility model is described in further detail below.

Fig. 1 is the partial structurtes schematic diagram of traditional vacuum booster mould;

Fig. 2 is the structural representation of the described vacuum booster of the utility model embodiment with the epithelium mould.

Among the figure:

1, cope match-plate pattern; 2, lower bolster; 3, middle template; 4, upper padding plate; 5, lower bolster; 6, patrix side opening; 7, bolt.

The specific embodiment

Shown in Fig. 1-2, vacuum booster described in the utility model epithelium mould, comprise cope match-plate pattern 1 and lower bolster 2, cope match-plate pattern 1 is respectively equipped with upper padding plate 4 and lower bolster 5 and fixing by bolt 7 respectively with lower bolster 2 outsides, template 3 in accompanying between described cope match-plate pattern 1 and the lower bolster 2, compare with traditional moulds, can make product be easy to, reduced the possibility that product is torn simultaneously; Offer patrix side opening 6 on the described cope match-plate pattern 1 and use the processing of moulding cutter, make product glossiness obtain effective assurance.

Claims (1)

1. a vacuum booster epithelium mould comprises cope match-plate pattern (1) and lower bolster (2), it is characterized in that: accompany middle template (3) between described cope match-plate pattern (1) and the lower bolster (2), offer patrix side opening (6) on the described cope match-plate pattern (1).
