Abstract
A powder metallurgy pressing mold for manufacturing sun gears of automobile starters comprises an upper pressing mold, a lower pressing mold, a pressing mandrel and a pressing forming concave mold. The upper pressing mold matches with the lower pressing mold vertically, the pressing forming concave mold is in slide fit with the upper pressing mold and the lower pressing mold, the upper pressing mold is hollow, and the pressing mandrel is placed in a gap of the upper pressing mold. The powder metallurgy pressing mold realizes one-step pressing forming of powder metallurgy, resolves problems that existing machinery wastes time and labor when in processing, is high in rejection rate and the like, simultaneously can be used for realizing mass production of the sun gears of the automobile starters, improves production efficiency, and reduces manufacturing cost of enterprises.
Description
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 automobile starter sun tooth.
Background technology
Automobile starter sun tooth is a part in the automobile start system, its structure as shown in figure 10, dimensional accuracy and inherent quality require than higher, manufacture difficulty is also big.Present this sun tooth is mainly made by mach mode by steel part forging and pressing back, it is not meticulous that but the method for machining exists processing usually, 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 powder metallurgy process to make auto parts and components is everybody common ideas, but other producers also do not have a kind of powder metallurgy pressing mould that is used for making automobile starter sun tooth specially.
The utility model content
At the deficiency that above-mentioned prior art exists, the utility model provides a kind of powder metallurgy pressing mold tool that is used to make automobile starter sun tooth, realizes purposes such as product one-shot forming and the high percent defective of precision are low.
A kind of powder metallurgy pressing mould of making automobile starter sun tooth; comprise compacting patrix, compacting counterdie, compacting core bar, compression moulding die; the compacting patrix cooperates up and down with the compacting counterdie; the compression moulding die is slidingly matched with compacting patrix, compacting counterdie; the compacting patrix is hollow form, and the compacting core bar places the space of compacting patrix.
The utility model has the advantages that: 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 automobile starter sun tooth in enormous quantities simultaneously, improve production efficiency, reduced enterprise's manufacturing cost.

The specific embodiment
Now in conjunction with the accompanying drawings, the utility model is further described.
As shown in Figure 1, a kind of powder metallurgy pressing mould of making automobile starter sun tooth, comprise compacting patrix 1, compacting counterdie 2, compacting core bar 3, compression moulding die 4, compacting patrix 1 cooperates up and down with compacting counterdie 2, compression moulding die 4 is slidingly matched with compacting patrix 1, compacting counterdie 2, compacting patrix 1 is hollow form, and compacting core bar 3 places the space of compacting patrix 1.As Fig. 2, shown in Figure 3, compacting patrix 1 is in order to airtight compacting counterdie 2 and the downward parts that transmit pressure to powder from top in the compacting; As Fig. 4, shown in Figure 5, compacting counterdie 2 cooperates the main part of compacting patrix 1 moulding sun tooth from bottom to top; As Fig. 6, shown in Figure 7, the circular hole in the middle of the compacting core bar 3 moulding sun teeth; As Fig. 8, shown in Figure 9, compression moulding die 4 is used for location compacting patrix 1 and compacting counterdie 2, and the moulding of the peripheral dentalation of sun tooth is had effect.
During compacting, compacting patrix 1 is depressed, and compacting core bar 3 enters compacting patrix 1, and compacting patrix 1 enters compression moulding die 3, and compacting patrix 1 is depressed into and requires highly to go up, and compacting counterdie 2 will press embryo to eject from compression moulding die 3.
