The pin in portion, described gear piece mould wheel include the straight-tooth mould wheel engaged with small tooth and the scroll wrap mould wheel engaged with canine tooth；It is described
The fit on of scroll wrap mould wheel be provided with bearing, the bearing inner race is interference fitted with scroll wrap mould wheel outer wall, bearing outer ring then with
Die shoe is fixed；It is cased with ejecting the push rod of duplicate gear outside described pin.
Further, in order to facilitate feeding, and two duplicate gears are manufactured simultaneously, improve production efficiency, divide in upper bolster
Ju You not two symmetrically arranged feeding pipes.
" mouth " type structure that described scroll wrap mould wheel is open for one side, and Open Side Down and wraps up the epimere of straight-tooth mould wheel
Part.The big gearing part of duplicate gear is divided into scroll wrap, scroll wrap mould wheel opening and including straight-tooth mould wheel corresponding to small toothed portion, and two
The Position Design of individual gear piece mould wheel is then more reasonable compact.
Further, in order to effectively control push rod jacking to act, push rod bottom is connected with top plate, and the top plate connects with cylinder
Connect and by cylinder command displacement.Action when, by being pushed up on cylinder controlroof, top plate can then drive with the push rod of top plate clamping
The top demoulding.
The beneficial effects of the utility model are duplicate gear provided by the utility model powder metallurgically manufacturing moulds, knot
Structure is simple, rationally designs the mould wheel at corresponding scroll wrap and the bearing with mould wheel interference fit, knock-pin is ejected duplicate gear
When, when scroll wrap is ejected upwards, it can be rotated with dynamic vortex tooth mould wheel, it is de- that the scroll wrap engaged with mould wheel can carry on the back smoothly ejection
Mould, knockout course are convenient and swift.

Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
A kind of duplicate gear powder metallurgically manufacturing mould as shown in Figures 1 to 4, it is the optimal implementation of the utility model
Example for manufacturing small tooth is straight-tooth, the duplicate gear that canine tooth is scroll wrap, including top mold frame 1, upper bolster 2, die shoe 3 and under
Mould bases 4, upper bolster 2 is interior to be provided with the feeding pipe 5 connected with charging aperture.In order to facilitate feeding, and two duplex-gears are manufactured simultaneously
Wheel, production efficiency is improved, there are two symmetrically arranged feeding pipes 5 respectively in upper bolster 2.In actual design, in order to equal
Even feeding, ensures gear even density, and each feeding pipe 5 is preferably the pipeline for being divided into three tunnels.
The upper surface of die shoe 3, which then corresponds to feeding pipe 5, has the gear piece mould wheel for making gear forming, the gear piece mould wheel lower end
Toothholder 6 is then fixed with, the central part of toothholder 6 has the pin 7 through gear piece mould wheel central part.Described gear piece mould wheel includes
The straight-tooth mould wheel 8 engaged with small tooth and the scroll wrap mould wheel 9 engaged with canine tooth.Described scroll wrap mould wheel 9 is one side opening
" mouth " type structure, and Open Side Down and wraps up the upper portion of straight-tooth mould wheel 8.The big gearing part of duplicate gear is divided into scroll wrap, whirlpool
Rotation tooth mould wheel 9 is open and including straight-tooth mould wheel 8 corresponding to small toothed portion, the Position Designs of two gear piece mould wheels then more it is reasonable tightly
Gather.
The fit on of scroll wrap mould wheel 9 is provided with bearing 10, and the inner ring of bearing 10 is interference fitted with the outer wall of scroll wrap mould wheel 9,
The outer ring of bearing 10 is then fixed with die shoe 3；It is cased with ejecting the push rod 11 of duplicate gear outside described pin 7.In order to effectively control
The jacking of push rod 11 action processed, the bottom of push rod 11 are connected with top plate 12, and the top plate 12 is connected with cylinder and by cylinder command displacement.
Top plate can be arranged on by guide pillar below lower mold holder, and is connected with cylinder.In action, by being pushed up on cylinder controlroof 12,
Top plate 12 can then drive to be stripped with being pushed up on the push rod 11 of the clamping of top plate 12.
In operating room, raw material pass through feeding pipe 5 enter die shoe 3, in the die cavity that gear piece mould wheel and pin 7 are formed into
Type., can be by being pushed up on cylinder controlroof 12 when duplicate gear needs the demoulding, top plate 12 drives push rod 11 to act upwards.This
When small toothed portion due to being straight-tooth, straight-tooth mould wheel 8 that can be directly along engagement is upward, and the scroll wrap of canine tooth part, then can band
The dynamic scroll wrap mould wheel 9 engaged with scroll wrap, scroll wrap mould wheel 9 rotate under the effect of bearing 10, and big gearing part is then along whirlpool
Revolve the direction of rotation engagement rotation of tooth mould wheel 9 and on, until the demoulding completely.
