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 a suit nozzle in the outside nut cover, is provided with discharging opening around the nozzle, and the outside nut cover is connected with the interior runner discharge port end of die head.The injection-moulding nozzle of this structure is through the mould jack-up nozzle that makes progress when spraying raw material, make nozzle and outside nut inner room form certain clearance after, by the nozzle outside injection of discharging opening all around.Because the gap of nozzle and outside nut inner room is less, material makes the injection machine cisco unity malfunction in regular meeting is blocked in the gap between outside nut cover and nozzle; At this moment the workman will remove to draw the material that is blocked in nozzle and outside nut inner room with hand; Equipment is remained in operation, and so, injection machine will quit work; Delay the production time, reduced production efficiency; In addition, the workman removes to draw the material that is blocked in nozzle and outside nut inner room with hand, is easy to occur industrial accident, and production safety does not ensure.
Summary of the invention
The technical problem that the present invention will solve is, is prone to stop up to nozzle in the prior art injection moulding process, needs artificial often cleaning to stop up material; Production efficiency is low, and industrial accident takes place frequently, and production safety does not have the defective of guarantee; A kind of two-color plastic rain shoes injection machine automated injection device is provided, can solves material well and stop up, production efficiency is low; Industrial accident takes place frequently, and production safety does not have the problem of guarantee.
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 the base; The rear end of said die head is provided with charging aperture, and the screw rod cover is fixed on the charging aperture place, and feed worm is sleeved in the screw rod cover, is connected with charging aperture, is provided with the envelope stub bar in the charging aperture; Vertically be provided with runner in the said die head, the stem of runner is tightly connected the bottom of the afterbody of runner to die head with the envelope stub bar; 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 the trepanning; The stem of drag link sleeve is fixed on the die head through the gland of die head front end, and the afterbody of drag link sleeve is provided with through hole, and drag link sleeve is vertical with runner to be provided with; Runner passes the through hole of drag link sleeve afterbody, to the bottom of die head; Plug-in mounting pull bar in the 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.
Suit cooling water box on the pull bar between said die head and the cylinder, the cooling water box is provided with water inlet pipe and outlet pipe.
The somewhat larger in diameter of said drag link sleeve, pull bar is in the diameter of runner.
Advantage of the present invention and beneficial effect are:
1, saved nozzle and outside nut cover, driven pull bar by cylinder, the discharging of control runner, runner is unobstructed when guaranteeing the material injection, the material clogging can not occur, but the injection machine continuous operation has improved production efficiency and operating efficiency;
2, stop the generation of material clogging, need not the labor cleaning, therefore industrial accident can not take place, guaranteed production safety;
3, drive pull bar work by cylinder, all automation is accomplished, and saves production cost, and improves the quality of production and product quality.

Fig. 1 is a stereogram of the present invention.
Fig. 2 is a die head rear end side view.
Fig. 3 is that the B-B of Fig. 2 is to cutaway view.
Wherein: the 1-die head, the 2-pull bar, the 3-drag link sleeve, the 4-cylinder, the 5-charging aperture, 6-seals stub bar, 7-runner, 8-cooling water box 9-gland, 10-piston, 11-through hole, 12-feed worm, 13-base, 14-screw rod cover, 15-water inlet pipe, 16-outlet pipe.
The specific embodiment
Embodiment: as shown in the figure, a kind of two-color plastic rain shoes injection machine automated injection device, it comprises die head 1, pull bar 2, drag link sleeve 3 and cylinder 4, said die head 1, cylinder 4 are fixed on the base 13; The rear end of said die head 1 is provided with charging aperture 5, and screw rod cover 14 is fixed on charging aperture 5 places, and feed worm 12 is sleeved in the screw rod cover 14, is connected with charging aperture 5, is provided with envelope stub bar 6 in the charging aperture 5; Vertically be provided with runner 7 in the said die head 1, the stem of runner 7 is tightly connected the bottom of the afterbody of runner 7 to die head 1 with envelope stub bar 6; The front end edge die head thickness direction of said die head 1 is provided with trepanning in die head; Plug-in mounting drag link sleeve 3 in the trepanning; The stem of drag link sleeve 3 is fixed on the die head 1 through the gland 9 of die head 1 front end, and the afterbody of drag link sleeve 3 is provided with through hole 11, drag link sleeve 3 and runner 7 vertical settings; Runner 7 passes the through hole 11 of drag link sleeve 3 afterbodys, to the bottom of die head 1; Plug-in mounting pull bar 2 in the said drag link sleeve 3, the stem of pull bar 2 is connected with the piston 10 of cylinder 4, the afterbody of pull bar 2 and runner 7 movable sealings; The diameter of said drag link sleeve 3, pull bar 2 is respectively 16mm and 15mm, and the diameter of runner 7 is 12mm; Suit cooling water box 8 on the pull bar 2 between said die head 1 and the cylinder 4, cooling water box 8 are provided with water inlet pipe 15 and outlet pipe 16.
