Description
Technical field
The invention belongs to a kind of injection-moulding device, more particularly, relate to a kind of two-color plastic rain shoes injection machine automated injection device.
Background technology
At present, the injection nozzle of two-color plastic rain shoes injection machine is suit nozzle in outside nut cover, and the surrounding of nozzle is provided with discharging opening, and outside nut cover is connected with the runner discharge port end in die head.The injection-moulding nozzle of this structure, when spraying raw material, is by mould upwards jack-up nozzle, after making nozzle and outside nut inner room form certain gap, by the outside injection of the discharging opening of nozzle surrounding.Because the gap of nozzle and outside nut inner room is less, material often can be blocked in the gap between outside nut cover and nozzle, make injection machine cisco unity malfunction, at this moment workman will remove to draw with hand the material being blocked in nozzle and outside nut inner room, equipment just can be made to remain in operation, and so, injection machine will quit work, delay the production time, reduce production efficiency; In addition, workman removes to draw the material being blocked in nozzle and outside nut inner room with hand, and be easy to occur industrial accident, production safety does not ensure.
Summary of the invention
The technical problem to be solved in the present invention is, easily block for nozzle in prior art injection moulding process, need artificial often cleaning blocking material, production efficiency is low, and industrial accident takes place frequently, the defect that production safety does not ensure, there is provided a kind of two-color plastic rain shoes injection machine automated injection device, can solve feed blocking well, production efficiency is low, industrial accident takes place frequently, the problem that production safety does not ensure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of two-color plastic rain shoes injection machine automated injection device, and it is characterized in that: it comprises die head, pull bar, drag link sleeve and cylinder, said die head, cylinder are fixed on base; The rear end of said die head is provided with charging aperture, and screw sleeve is fixed on charging aperture place, and feed worm is sleeved in screw sleeve, is connected with charging aperture, is provided with envelope stub bar in charging aperture; Longitudinally is provided with runner in said die head, the stem of runner is tightly connected with envelope stub bar, and the afterbody of runner is to the bottom of die head; The front end edge die head thickness direction of said die head is provided with trepanning in die head, plug-in mounting drag link sleeve in trepanning, the stem of drag link sleeve is fixed on die head by the gland of die head front end, the afterbody of drag link sleeve is provided with through hole, drag link sleeve is vertical with runner to be arranged, runner passes the through hole of drag link sleeve afterbody, to the bottom of die head; Plug-in mounting pull bar in said drag link sleeve, the stem of pull bar is connected with the piston of cylinder, the afterbody of pull bar and runner movable sealing.
Pull bar between said die head and cylinder is set with cooling water box, cooling water box is provided with water inlet pipe and outlet pipe.
The diameter of said drag link sleeve, pull bar is slightly larger than the diameter of runner.
Advantage of the present invention and beneficial effect are:
1, eliminate nozzle and outside nut cover, drive pull bar by cylinder, control flow check way discharging device, when ensureing that material sprays, runner is unobstructed, there will not be feed blocking phenomenon, and injection machine can continuous operation, improves production efficiency and operating efficiency;
2, stopped the generation of feed blocking phenomenon, without the need to labor cleaning, therefore industrial accident can not occur, ensure that production safety;
3, drive pull bar work by cylinder, whole automation completes, and saves production cost, and improves the quality of production and product quality.
