Description

The injection mold of Automatic clearance die cavity
Technical field
The utility model relates to a kind of mould, and more particularly, it relates to a kind of injection mold of Automatic clearance die cavity.
Background technology
Mould, in industrial production in order to injection moulding, blowing, extrude, various moulds and instrument that the method such as die casting or forging forming, smelting, punching press, stretching obtains required product.In brief, mould is the instrument for formed article, and this instrument consists of various parts, and different moulds consists of different parts.
Injection mold has accounted for a very large proportion in mould, punch on injection mold and die form a shaping area in matched moulds, then by the material injection moulding district of melting, wait expecting after cooling to have obtained needed product, and before injection mo(u)lding, in die cavity, be easily detained some magazines, affect crudy.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of injection mold of Automatic clearance die cavity.
For achieving the above object, the utility model provides following technical scheme: a kind of injection mold of Automatic clearance die cavity, comprise cope match-plate pattern, punch, die, push rod, ejector pin retaining plate, push pedal and lower bolster, described punch is connected with cope match-plate pattern, described die and punch are suitable, described die is provided with push-rod hole, described push rod is connected with ejector pin retaining plate, described push rod is connected with die by push-rod hole, described ejector pin retaining plate is connected with push pedal, described push pedal is connected with lower bolster, described die is provided with die cavity, the sidewall of described die cavity is provided with groove, the sidewall of described groove is provided with passage, described passage comprises air inlet section and the section of giving vent to anger, the described section of giving vent to anger is positioned between air inlet section and groove, the described section of giving vent to anger is towards core bottom angled, in described passage, be equipped with breather pipe, described breather pipe is connected with air jet system, on described punch, be fixed with the projection suitable with groove.
The utility model is further set to: described air jet system is air pump.
The utility model is further set to: the end face of the described relative die of projection is provided with chute, is provided with the slide block of thrust spring and slip in described chute, and one end of described slide block protrudes from chute, and described chute can be accommodated slide block.
The utility model is further set to: described projection and punch removably connect by screw.
Compared with prior art, the beneficial effects of the utility model are: at punch and the die matched moulds of processing, air jet system quits work, projection is just in time blocked groove, thereby can not have influence on the normal injection molding of mould, after injection formed, punch separates with die, now projection departs from groove, push rod ejects the part processing, air jet system work simultaneously, by breather pipe, gas is sprayed from fumarole, and the section of giving vent to anger is pointed to die cavity, therefore gas is all sprayed onto on die cavity, the foreign material that some are remained in die cavity spray, the part processing is had to certain cooling effect simultaneously.

The specific embodiment
Referring to figs. 1 through Fig. 5, the injection mold embodiment of the utility model Automatic clearance die cavity is described further.
A kind of injection mold of Automatic clearance die cavity, comprise cope match-plate pattern 1, punch 2, die 3, push rod 7, ejector pin retaining plate 5, push pedal 4 and lower bolster 6, described punch 2 is connected with cope match-plate pattern 1, described die 3 is suitable with punch 2, described die 3 is provided with push-rod hole 31, described push rod 7 is connected with ejector pin retaining plate 5, described push rod 7 is connected with die 3 by push-rod hole 31, described ejector pin retaining plate 5 is connected with push pedal 4, described push pedal 4 is connected with lower bolster 6, described die 3 is provided with die cavity 32, the sidewall of described die cavity 32 is provided with groove 34, the sidewall of described groove 34 is provided with passage 33, described passage 33 comprises air inlet section 332 and the section of giving vent to anger 331, the described section of giving vent to anger 331 is between air inlet section 332 and groove 34, the described section of giving vent to anger 331 is towards core 21 bottom angled, in described passage 33, be equipped with breather pipe 10, described breather pipe 10 is connected with air jet system 9, described air jet system 9 is air pump, on described punch 2, be fixed with the projection 11 suitable with groove 34.
Punch 2 and die 3 matched moulds in processing, air pump quits work, projection 11 is just in time blocked groove 34, thereby can not have influence on the normal injection molding of mould, after injection formed, punch 2 separates with die 3, now projection 11 departs from groove 34, push rod 7 ejects the part processing, and air pump work, makes gas spray from fumarole by breather pipe 10 simultaneously, and the section of giving vent to anger 331 is pointed to die cavity 32, therefore gas is all sprayed onto on die cavity 32, and the foreign material that some are remained in die cavity 32 spray, and the part processing are had to certain cooling effect simultaneously.
Wherein, the end face of projection 11 relative dies 3 is provided with groove 34, the slide block 13 that is provided with thrust spring 12 in described groove 34 and slides, one end of described slide block 13 protrudes from chute 111, and described chute 111 can be accommodated slide block 13, when punch 2 can contact with die 3, slide block 13 can first contact with groove 34 bottoms, and thrust spring 12 produces compression, thereby can play certain buffering effect, in the time of punch 2 and die 3 matched moulds, slide block 13 is the whole chute 111 that is positioned at just in time.
For convenient, projection 11 is changed, projection 11 and punch 2 removably connect by screw 8.
