Abstract
A spraying head with an overflow-preventing structure on an injection molding machine comprises a connecting pipe and a spraying nozzle, wherein the spraying nozzle is connected to the connecting pipe in a screwed mode. An inclined hole penetrating through the outer wall of the spraying nozzle is formed in the inner wall on the lower side of a spraying opening of the spraying nozzle, a pipe connector is connected into the inclined hole of the spraying nozzle in a screwed mode and is connected to a liquid return pipe, the liquid return pipe is fixed to a first solenoid valve, the first solenoid valve is fixed to a temporary storage cylinder, and a liquid inlet is formed in the upper end of the temporary storage cylinder. The first solenoid valve is communicated with the liquid inlet. A liquid return air cylinder is fixed to the lower end of the temporary storage cylinder, a piston rod of the liquid return air cylinder extends into the temporary storage cylinder and is fixedly connected to a piston, the outer wall of the piston abuts against the inner wall of the temporary storage cylinder, and a discharge hole is formed in the part, above the piston, of the temporary storage cylinder. A second solenoid valve is fixed to the temporary storage cylinder, is communicated with the discharge hole and is connected to a discharge pipe. According to the structure, after the spraying head injects fused plastic into an injection mold, the fused plastic left in the spraying head can be recovered and discharged.
Description
Technical field:
The present invention relates to the technical field of injection machine, more specifically to the shower nozzle with anti-overflow structure on a kind of injection machine.
Background technology:
The spout of current sprayer of injection molding machine front portion passes through tapered pole transition by injection mould shower nozzle cylindrical cavity, so the shower nozzle of injection mould shower nozzle is very little, and during injection machine injection moulding, melt plastic cement sprays from injection mould shower nozzle, existing injection machine completely accurately cannot control the amount of the melt plastic cement of injection mould shower nozzle, thus after injection mould shower nozzle has noted melt plastic cement in injection mould, melt plastic cement fraction in carrier pipe remains in shower nozzle, or overflow the spout of shower nozzle, its residual melt plastic cement not only affects the injection moulding of the melt plastic cement of downside unlike material, and its easy frozen plug shower nozzle.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and provides the shower nozzle with anti-overflow structure on a kind of injection machine, and it can reclaim the melt plastic cement remaining in shower nozzle after shower nozzle has noted melt plastic cement to injection mould, avoids use the next time affecting shower nozzle.
Shower nozzle with anti-overflow structure on a kind of injection machine, comprise tube connector and nozzle, nozzle is screwed onto on tube connector, the shaping inclined hole running through outer nozzle wall on inwall on the downside of nozzle vent, pipe joint is bolted with in the inclined hole of nozzle, pipe joint is connected with liquid back pipe, liquid back pipe is fixed on the first magnetic valve, first magnetic valve is fixed on buffer memory cylinder, the upper end of buffer memory cylinder forms inlet, first magnetic valve is connected with inlet, the lower end of buffer memory cylinder is fixed with back liquid cylinder, the piston rod returning liquid cylinder stretches into buffer memory cylinder interior and is fixedly connected with piston, the outer wall of piston is against on the inwall of buffer memory cylinder, buffer memory cylinder on the upside of piston forms outage, buffer memory cylinder is fixed with the second magnetic valve, second magnetic valve is connected with outage, second magnetic valve is connected with discharging tube, described buffer memory cylinder is fixed on tube connector by support.
The first described magnetic valve and the second magnetic valve adopt miniature electromagnetic valve, and the first magnetic valve and the second magnetic valve are all fixed on the upper end of buffer memory cylinder.
Beneficial effect of the present invention is:
The nozzle structure that it adopts can reclaim the melt plastic cement remaining in shower nozzle after shower nozzle has noted melt plastic cement to injection mould, and by the discharge of residual melt plastic cement, avoids use the next time affecting shower nozzle.
Accompanying drawing illustrates:

Detailed description of the invention:
Embodiment: see Fig. 1, 2, shown in 3, shower nozzle with anti-overflow structure on a kind of injection machine, comprise tube connector 1 and nozzle 2, nozzle 2 is screwed onto on tube connector 1, the shaping inclined hole 21 running through nozzle 2 outer wall on inwall on the downside of nozzle 2 spout, pipe joint 3 is bolted with in the inclined hole 21 of nozzle 2, pipe joint 3 is connected with liquid back pipe 4, liquid back pipe 4 is fixed on the first magnetic valve 5, first magnetic valve 5 is fixed on buffer memory cylinder 6, the upper end of buffer memory cylinder 6 forms inlet 61, first magnetic valve 5 is connected with inlet 61, the lower end of buffer memory cylinder 6 is fixed with back liquid cylinder 7, the piston rod returning liquid cylinder 7 stretches into buffer memory cylinder 6 inside and is fixedly connected with piston 8, the outer wall of piston 8 is against on the inwall of buffer memory cylinder 6, buffer memory cylinder 6 on the upside of piston 8 forms outage 62, buffer memory cylinder 6 is fixed with the second magnetic valve 9, second magnetic valve 9 is connected with outage 62, second magnetic valve 9 is connected with discharging tube 10, described buffer memory cylinder 6 is fixed on tube connector 1 by support 11.
The first described magnetic valve 5 and the second magnetic valve 9 adopt miniature electromagnetic valve, and the first magnetic valve 5 and the second magnetic valve 9 are all fixed on the upper end of buffer memory cylinder 6.
Operation principle: the present invention is the shower nozzle with anti-overflow structure on injection machine, during its work, first magnetic valve 5, second magnetic valve 9 is all in normally off, spray melt plastic cement when shower nozzle but in shower nozzle, gone back remaining molten plastic cement, first magnetic valve 5 is opened, return liquid cylinder 7 to start, melt plastic cement in shower nozzle or outside shower nozzle spout is under the effect of returning liquid cylinder 7, by inclined hole 21, pipe joint 3, liquid back pipe 4 and the first magnetic valve 5 enter buffer memory cylinder 6, then the first magnetic valve 5 cuts out, second magnetic valve 9 is opened, return liquid cylinder 7 to reset, by the melt plastic cement in buffer memory cylinder 6 from the second magnetic valve 9, discharging tube 10 pipe is discharged, thus the melt plastic cement in shower nozzle also just can be prevented excessive.
