In middle model fixing seat 9, lower die 3 is arranged in lower model fixing seat 13.The end face of lower die 3 and the cavity inner surface of middle mould 1 form fire
Medicinal powder end filled cavity, 2 outer wall of upper mold, which is socketed with resistance and rushes down quick-fried set 4 and hinder, rushes down 4 sliding axially along 2 outer wall of upper mold of quick-fried set, in upper mold 2
It is rushed down in the cavity between quick-fried set 4 with resistance and is equipped with spring 5 and stop nut 6,5 one end of spring is fixedly connected with upper mold 2, and spring 5 is another
One end is rushed down quick-fried set 4 with resistance and is connect, and stop nut 6 is fixedly connected in upper mold 2, and the bottom surface of stop nut 6 is contacted with 1 end face of middle mould
When, it limits the descending stroke of upper mold 2 and limits the upward stroke of upper mold 2 when stop nut 6 rushes down quick-fried 4 clamping of set with resistance.
In embodiment, upper mold 2 is located at the resistance venting of dust explosion set 4 of 2 outer surface of upper mold first along upper into 1 direction moving process of middle mould
2 appearance of mould is slided towards middle mould 1, until resistance venting of dust explosion set 4 stops moving when the stop nut 6 of resistance venting of dust explosion set 4 is contacted with 1 end of middle mould
Dynamic, as 2 position of upper mold constantly declines, spring 5 is constantly extruded so that resistance venting of dust explosion set 4 is compacted, 2 stop motion of upper mold.This
Quick-fried set 4 is rushed down in the increased resistance of embodiment, and when upper mold 2 moves down, quick-fried set 4 is rushed down in resistance can be pressed on 1 upper surface of middle mould, can obstruct
And the energy of detonation generation occurs once in a while when being molded in 1 die cavity of middle mould by upper mold 2, lower die 3 for safe release, avoids igniting other
Station.
When upper mold 2 is lifted up, spring 5 drives resistance venting of dust explosion set 4 to move up, as 2 position of upper mold constantly rises, spring
5 restore elastic force, and resistance venting of dust explosion set 4 is connected together with stop nut 6,2 stop motion of upper mold.
2 end of upper mold in the present embodiment is equipped with semicircular end-face, and the end of the lower die 3 opposite with upper mold 2 also is provided with half
When circular end face, upper mold 2 and lower die 3 mold, cylindrical cavity is formed.User also can sets itself cavity shape as needed
Shape, to produce the powder grain 11 for meeting specific shape requirement.
4 bottoms of quick-fried set are rushed down in resistance and are additionally provided with cushion pad, and stress concentrates the gunpowder that ignites when avoiding compressing.
Conductive rubber telescopic 8 is socketed on 3 side wall of lower die, 8 top of conductive rubber telescopic connects tapered cap
7.The setting of tapered cap 7, conductive rubber telescopic 8 is in order to avoid gunpowder dust and other solution fall into lower die 3 and consolidate with lower die
Cause wiping, compression ignition accident in the gap that reservation 13 connects.
It is additionally provided with the sink 14 for collecting gunpowder dust in lower model fixing seat 13, water is housed in sink 14.Sink 14 can be beaten
The gunpowder dust and solution that wet and dilution is fallen from 1 gap of lower die 3 and middle mould, to increase the safety of production.
The process of each component cooperating is as follows in the present embodiment：
When upper mold 2 is in upper pole location, it has been filled in the gunpowder powder filled cavity being made of middle mould 1 and lower die 3 certain
The gunpowder of amount.Upper mold 2 is moved downward by mechanism driving, before upper mold 2 does not enter gunpowder powder filled cavity, resistance venting of dust explosion set 4
Mould 1 during lower surface has contacted.As 2 position of upper mold constantly declines, spring 5 is also constantly extruded.When upper mold 2 drops to lower pole
When point position, resistance venting of dust explosion set 4 has been compacted, and the gunpowder in gunpowder powder filled cavity has also been squeezed into powder grain
11.After pressure is kept for a period of time, upper mold 2 and lower die 3 are driven while being lifted up by mechanism, when in the emersion of powder grain 11
Behind 1 upper surface of mould, upper mold 2 continues to lift up, and resistance venting of dust explosion set 4 also takes up rising by stop nut 6.When mould 1 in 4 distance of resistance venting of dust explosion set
When upper surface distance is more than 11 full-size of powder grain, powder grain 11 is removed.Then, lower die 3 drops to designated position.
It is in the present embodiment that the operation principle of the device of moist gunpowder powder pressing forming is as follows：
It, will be in the moist fire powder of mixed alcohol is sent to lower die 3 and middle mould 1 forms gunpowder powder filled cavity in the present embodiment
（Gunpowder powder filled cavity volume calculates）.Upper mold 2 lowers into 1 die cavity of middle mould, squeezes in gunpowder powder filled cavity
Medicinal powder, by medicinal powder compression moulding.When medicinal powder compression moulding and after a period of stabilisation, upper mold 2, lower die 3 are simultaneously by mechanism urges
It moves upwards, takes powder grain after molding out of middle mould 1, lower die 3 is dropped to by mechanism driving after powder grain 11 is deviate from
Designated position.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
