The beneficial effect that the utility model brings has:
The utility model is improved by structure, provide that a kind of limit ejects, the two two air inlet ejection mold-opening structures of blowing in limit, as a kind of new stripping means, it is when mould die sinking ejects, two gas can enter inside product, make product Automatic-falling, so ensure that product does not rupture, indeformable, avoid product de-fracture by force, the phenomenons such as distortion occur, in addition its structural design advantages of simple, depanning difficulty and cost all greatly reduce, and surely belong to the important breakthrough of plastics spring vavuum pump production operation technological difficulties.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail,
Accompanying drawing 1 is structure schematic diagram of the present utility model.
Detailed description of the invention
With reference to accompanying drawing 1, the utility model is for we providing the two air inlet ejection mold-opening structure of a kind of vavuum pump, and it ejects two stripping means of blowing, and can effectively avoid product to take off the phenomenons such as fracture, distortion by force.
Concrete, as a kind of new stripping means, its structure mainly comprises patrix 1 and counterdie 2, die sinking die joint 3 is formed between patrix 1 and counterdie 2, wherein, counterdie 2 upper end is provided with formed product portion 4, connects product push part below its formed product portion 4, product push part comprises thimble, Ejector Retainer Plate 51 and top roller 52, and the connection of its sidepiece is provided with intake valve 6.
In said structure, formed product portion 4 symmetrically structure, is mainly reflected in it for bilateral symmetry, and be provided with two sleeve forming moulds 41 altogether before and after simultaneously in it, wherein every suit mould 41 is to there being a product push part.
Meanwhile, two ends, formed product portion 4 all offer inclined guide groove, when patrix 1 is in matched moulds state with counterdie 2, are provided with Angle Pin 7 in it.The arranged outside in formed product portion 4 has slide block 8, and it is fixed on the two ends in formed product portion 4 by Angle Pin 7, and when patrix 1 is in die opening state with counterdie 2, Angle Pin 7 and slide block 8 are just in succession opened and be convenient to die sinking.
In addition, above-mentioned top roller 52 is arranged at bottom counterdie 2, it is Ejector Retainer Plate 51 above it, thimble is installed in air inlet pipe, air inlet pipe top is positioned at mould 41, its lower end is communicated with the two place's intake valves 6 being arranged at counterdie 2, and Ejector Retainer Plate 51 drives thimble upwardly and opens intake valve 6 under the promotion of top roller 52.Therefore form that a kind of limit ejects, the two two air inlet ejection mold-opening structures of blowing in limit.
