Abstract

A powder metallurgy compressing mould for manufacturing a geared ring of an automobile starter comprises an end face press mould, a core bar and a compression moulding die, wherein an inner hole of the end face press mould is provided with a toothed structure matched with the core bar; the end face press mould is matched with the core bar through teeth; and the compression moulding die and the end face press mould are in sliding fit. Due to the powder metallurgy compressing mould of the utility model, the powder metallurgy is subject to once compressing moulding so as to solve the problems of time and energy waste, high rejection rate and the like in the previous machinery machining; and meanwhile, by using the powder metallurgy compressing mould of the utility model, the geared ring of the automobile starter can be produced in batches, so that the production efficiency is improved, and the manufacture cost of an enterprise is lowered.

Description

A kind of powder metallurgy pressing mould of making the automobile starter gear ring

Technical field

The utility model belongs to powder metallurgy die manufacturing technology field, is specifically related to a kind of powder metallurgy pressing mould that is used to make the automobile starter gear ring.

Background technology

The automobile starter gear ring is a part of automobile starter, its structure as shown in Figure 6, dimensional accuracy and inherent quality require than higher, manufacture difficulty is also big.Present this starter gear ring is mainly made by mach mode by steel part forging and pressing back, and that the method for machining exists processing usually is not meticulous, the part percent defective height that processes, and machining wastes time and energy, and increased the production cost of enterprise.Along with the continuous development of technology, adopting the powder metallurgy process car parts that steam next life is a kind of good solutions, but does not also have other producers' exploitations to make the powder metallurgy pressing mould of automobile starter gear rings on the market.

The utility model content

Purposes such as at the deficiency that above-mentioned prior art exists, the utility model provides a kind of powder metallurgy pressing mould that is used to make the automobile starter gear ring, realizes the product one-shot forming and the precision height that process, and percent defective is low.

A kind of powder metallurgy pressing mould of making the automobile starter gear ring; comprise end face pressing mold, core bar, compression moulding die; end face pressing mold endoporus has the dentalation that matches with core bar, and the end face pressing mold cooperates by tooth with core bar, and compression moulding die and end face pressing mold are slidingly matched.

Advantage of the present invention is: the utility model is with a compression moulding of powder metallurgy, problems such as machining wastes time and energy, percent defective height have been solved in the past, utilize the utility model can produce the automobile starter gear ring in enormous quantities simultaneously, improved production efficiency, reduced enterprise's manufacturing cost.
