Abstract
This utility model provides a kind of anti-lock mould for powder metallurgy, including upper die and lower die and middle mold, described upper mold has the upper punching pin of cylinder, described lower mold has the lower punching pin of cylinder, described middle mold has the die cavity of cylinder, and described upper punching pin is downwardly in middle mold from upper end, and described lower punching pin is inserted upwardly in middle mold from lower end, described lower punching pin offers several lower stock chests with coordinating of die cavity on face, the lower equidistant ring of stock chest is located on the outer wall of lower punching pin.This utility model is provided with stock chest (upper stock chest and lower stock chest) respectively on upper punching pin and lower punching pin, the contact area between upper and lower mould and middle mold can be reduced, thus reduce abrasion, reduce operating noise, stock chest can be used for storing powder (powder entering between upper and lower mould and middle mold) temporarily simultaneously, prevents mould stuck.
Description
Technical field
This utility model relates to powder metallurgy die field, particularly relates to a kind of anti-lock mould for powder metallurgy.
Background technology
Powder metallurgy is as raw material with metal dust (or mixture of metal dust and non-metal powder), through shaping
And sintering, manufacture various types of goods, be sintered metal product.
During powder metallurgy forming, middle mold storage powder, during upper die and lower die compacting, in order to prevent fine powder from running out of, between mould
Contact distance less.But owing to powder is less, although contact apart from smaller, but powder still can run to mould it
Between, increase ejection resistance, along with powder gets more and more, ejection resistance is increasing, eventually results in mould stuck.
Utility model content
The purpose of this utility model is to provide a kind of anti-lock mould for powder metallurgy, asks solving above-mentioned technology
Topic.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of anti-lock mould for powder metallurgy, it is characterised in that: include upper die and lower die and middle mold, described upper mold
Have cylinder upper punching pin, described lower mold have cylinder lower punching pin, described middle mold have cylinder die cavity, described on
Punching pin is downwardly in middle mold from upper end, and described lower punching pin is inserted upwardly in middle mold from lower end, and described lower punching pin is joined with die cavity
Offering several lower stock chests on conjunction face, the lower equidistant ring of stock chest is located on the outer wall of lower punching pin.
Described upper punching pin offers stock chest on several with coordinating of die cavity on face, the equidistant ring of upper stock chest is located at
On the outer wall of punching pin, upper stock chest is crisscross arranged with lower stock chest.
The bottom land of described upper stock chest and lower stock chest is arc surface.To ensure upper punching pin and the intensity of lower punching pin, and
And it is convenient to clean the powder collected.
The beneficial effects of the utility model are:
This utility model is provided with stock chest (upper stock chest and lower stock chest) respectively on upper punching pin and lower punching pin, can
To reduce the contact area between upper and lower mould and middle mold, thus reducing abrasion, reduce operating noise, stock chest can be used for facing simultaneously
Time store powder (entering into the powder between upper and lower mould and middle mold), prevent mould stuck.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, under
Face with specific embodiments and the drawings, is expanded on further this utility model, but following embodiment is only of the present utility model excellent

Lower the obtained other embodiments of premise, broadly falls into protection scope of the present invention.
Specific embodiment of the utility model is described below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of anti-lock mould for powder metallurgy, including upper mold 1, lower mold 6 and middle mold 3, upper mold 1 has
Having the upper punching pin 2 of cylinder, lower mold 6 has the lower punching pin 5 of cylinder, and middle mold 3 has the die cavity 4 of cylinder, and upper punching pin 2 is from upper
End is downwardly in middle mold 3, and lower punching pin 5 is inserted upwardly in middle mold 3 from lower end, and lower punching pin 5 offered on face with coordinating of die cavity 4
Several lower stock chests 7, the lower equidistant ring of stock chest 7 is located on the outer wall of lower punching pin 5；Upper punching pin 2 coordinates on face with die cavity 4
Offering stock chest 8 on several, the upper equidistant ring of stock chest 8 is located on the outer wall of punching pin 2, upper stock chest 8 and lower storing
Groove 7 is crisscross arranged.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Be only preference of the present utility model, be not intended to limit this utility model, without departing from this utility model spirit and scope
On the premise of, this utility model also has various changes and modifications, and these changes and improvements both fall within this claimed practicality
In novel scope.This utility model claims scope and is defined by appending claims and equivalent thereof.
