Abstract

The utility model discloses a dustproof ring mold, and particularly discloses a mold for manufacturing a U-shaped dustproof ring. The dustproof ring mold is provided with an upper mold and a lower mold, wherein the upper mold and the lower mold are correspondingly arranged in an up-down manner to form model cavities; the upper mold is provided with small grooves and bulges; the lower mold is provided with large grooves. The model cavities formed after the upper mold and the lower mold are enclosed correspondingly are circular, the transverse sections of the model cavities are U-shaped, and small semi-circular bulges are formed on the tops of the U shapes. In the demolding process, the dustproof ring can be separated from the lower mold very conveniently, so that time and force are saved, and the production cost is lowered. Moreover, the joint surfaces of the upper mold and the lower mold are positioned beside the bulges on the tops of the U shapes, so that flashes can be removed easily in the subsequent flash removing process even though the flashes are formed, and the production efficiency is improved greatly.

Description

Dust ring mould

Technical field

The utility model relates to a kind of dust ring mould, especially a kind of mould for the manufacture of U-shaped dust ring.

Background technology

General U-shaped dust ring mould is made up of upper and lower mould now, adopts locating core docking to form between upper and lower mould, and between upper and lower mould, Formation cross-section is U-shaped model cavity.Because upper and lower mould adopts positioning core axle docking, in the process of the demoulding, after opening patrix, U-shaped dust ring can embed in counterdie, is not easy to spin off from counterdie, so the demoulding is wasted time and energy, has increased production cost.Also there are some moulds, the die joint of its upper die and lower die is at the middle part of U-shaped cavity, although the demoulding can become easy like this, but be easy to produce overlap at the middle part of U-shaped dust ring, affect the quality of product, and the later stage remove overlap also waste time and energy very much, remove the improper substandard products that also can cause producing.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of dust ring mould, and this dust ring mould can be manufactured U-shaped dust ring, and its knockout course is very easy simple, and the U-shaped dust ring quality of producing is good, can be time saving and energy saving, reduce production costs.

For solving the problems of the technologies described above, dust ring mould of the present utility model has upper die and lower die, the upper and lower corresponding composition model cavity of described upper die and lower die, and described patrix has little groove and projection, and described counterdie has big groove.

Described little groove has 2, is all ring shape, cross section semicircular in shape.

Described projection has 1, is ring shape, and cross section takes the shape of the letter U.

Described big groove has 1, is ring shape, and cross section takes the shape of the letter U.

Described model cavity is ring shape, and its cross section is U-shaped.

After adopting such structure, upper die and lower die composition model cavity, model cavity entirety is ring shape, its cross section is U-shaped, because patrix has little groove, so can produce semicircular small lugs at the U-shaped top of U-shaped dust ring, in knockout course, utilize small lugs can very easily make U-shaped dust ring depart from counterdie, time saving and energy saving, improve production efficiency.Because the die joint of upper die and lower die is positioned at by small lugs, the overlap of the product quality that can not exert an influence, has produced overlap in time, owing to being top at U-shaped dust ring, is also very easy to remove, and can not cause substandard products, has improved the qualification rate of product.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 1 is the schematic diagram of the embodiment of the utility model dust ring mould.

In figure, the 1st, patrix, the 2nd, counterdie, the 3rd, model cavity, the 4th, little groove, the 5th, projection, the 6th, big groove.

The specific embodiment

There is patrix 1 and counterdie 2 according to the dust ring mould shown in Fig. 1, the upper and lower corresponding composition model cavity 3 of described patrix 1 and counterdie 2, described patrix 1 has little groove 4 and projection 5, and described counterdie 2 has big groove 6; Described little groove 4 has 2, is all ring shape, cross section semicircular in shape; Described projection 5 has 1, is ring shape, and cross section takes the shape of the letter U; Described big groove 6 has 1, is ring shape, and cross section takes the shape of the letter U; Described model cavity 3 is ring shape, and its cross section is U-shaped.

When use, patrix 1 and counterdie 2 are closure state, and the model cavity 3 of corresponding composition is circular, and cross section is U-shaped; After dust ring moulding, carry out the demoulding, open patrix 1, can see that dust ring major part is in counterdie 2, but the projection on upper edge is exposed to outside, can easily dust ring be taken out from counterdie 2, time saving and energy saving, reduce production cost.Because die joint is positioned at the projection place of U-shaped dust ring, so be not easy to form overlap, even if there is a small amount of overlap, in follow-up removal process, also can very easily remove, improve production efficiency.

Above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops on protection domain of the present utility model.
