Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1-3, in the embodiment of the present invention, a kind of high-efficiency injection molding machine structure for injection machine, comprise extrusion mechanism, injection device and at least two moulds 8, described injection device connects each mould 8 by least one feeding distribution mechanism, suppose that these feeding distribution mechanisms are connected to abundant mould 8, injection device carries out injection moulding by feeding distribution mechanism to a mould 8, when this mould 8 injection step completes, when then carrying out follow-up operation, injection device then carries out injection moulding by feeding distribution mechanism to another mould 8, the injection moulding of a mould 8 is complete, feeding distribution mechanism just connects the mould 8 of another free time, until first mould 8 completes all process steps, get out second time injection moulding, feeding distribution mechanism connects this mould again, no matter follow-up operation has how many, as long as these feeding distribution mechanisms are connected abundant mould 8, just can utilize the time fully, that goes round and begins again carries out injection moulding to these moulds 8, utilize the time to greatest extent, increase work efficiency, reduce the time that injecting mechanism is waited for as far as possible.
Described feeding distribution mechanism comprises housing 5, at least one changer lever 3 and and the same number of reciprocating mechanism of changer lever 3, charging hole 501 and at least one discharge opening 502 is provided with in described housing 5, the entrance of described charging hole 501 exports with injection device and is connected, the outlet of each discharge opening 502 all connects with the entrance of corresponding mould 8, the outlet of charging hole 501, the entrance of each discharge opening 502 is all connected with changer lever 3, changer lever 3 end connects reciprocator, changer lever 3 front end is inserted in housing 5, changer lever 3 is provided with the connecting hole 301 that at least one can connect charging hole 501 outlet and corresponding discharge opening 502, each connecting hole 301 is arranged in order along the longitudinal direction of changer lever 3.
Because reciprocator drives changer lever 3 to move back and forth, therefore changer lever 3 has two states: first state, reciprocator drives changer lever 3 to move, a link slot on changer lever 3 moves to just in time between the outlet and the entrance of a discharge opening 502 of charging hole 501, connect the outlet of charging hole 501 and the entrance of a discharge opening 502, injection device just can will come from the material injection of extrusion mechanism in the mould 8 be connected with this discharge opening 502; Second state, reciprocator drives changer lever 3 to move, and changer lever 3 does not have link slot place between the outlet and the entrance of each discharge opening 502 of charging hole 501; Described reciprocating mechanism is cylinder 4.
