Suction chamber is equipped with the opening for being connected to injecting cavity close to one end of nozzle, is equipped with piston in suction chamber, piston is far from nozzle
Side is connected with push-pull rod, push-pull rod with suction chamber be set connect far from the cylinder of nozzle one end, the suction chamber is far from spray
One end of mouth is also connected with exhaust tube, and exhaust tube is overlapped with the central axis of injection screw, and exhaust tube is retracting cylinder.
When the utility model is used, injection screw rotates, so that the injection molding material in injecting cavity be squeezed out from nozzle, realizes note
Modeling after the completion of injection molding, starts cylinder, keeps push-pull rod mobile to the direction far from nozzle with piston, thus by nozzle and injection
In intracavitary remaining injection molding material inspiration suction chamber, it is effectively prevent water clock, when piston is mobile, the air in suction chamber is then through exhaust tube
Discharge, and exhaust tube is retracting cylinder, can adaptively follow the movement of injection screw.
Further, the screw rod wall between suction chamber and injecting cavity is equipped with heating chamber, is equipped with electric heating wire in heating chamber,
Electric heating wire is connect with external power supply.
Further, opening cooperates with piston, so that piston stretches out opening, and piston and nozzle cooperate.It inhales
When entering intracavitary injection molding material discharge, start cylinder, push-pull rod band piston is mobile to nozzle direction, and piston is made to enter nozzle
Interior, so as to which injection molding material to be thoroughly discharged, cleaning effect is good, and can avoid manual cleaning, time saving and energy saving.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1. by the way that suction chamber is arranged in injection screw, injection molding material remaining in nozzle and injecting cavity is inhaled for the utility model
Enter, water clock can be effectively prevent, and avoid in nozzle remaining injection molding material by cooling solidification plug nozzle；
2. the utility model is entered in nozzle by making piston stretch out opening, so as to which injection molding material to be thoroughly discharged, clearly
It is good to manage effect, and can avoid manual cleaning, it is time saving and energy saving.
