Abstract
Injection machine mould ejects protective loop, comprises ejection cylinder, solenoid directional control valve and overflow valve, and ejection cylinder top is moved back between chamber and oil return line and arranged solenoid directional control valve, and ejection cylinder ejects between chamber and oil return line and arranges overflow valve.Owing to being provided with the mould ejection protective loop of solenoid directional control valve and overflow valve composition; if injection machine is matched moulds under mold ejection mechanism does not fall back on a situation; top can be realized and move back chamber by solenoid directional control valve repairing; eject chamber by overflow valve oil return; realize ejecting mechanism rollback, play the effect of protection mould, therefore; it can realize the stop of ejecting mechanism in any position, can protect again the safety of mould.
Description
Technical field
The utility model relates to a kind of injection machine mould protective loop.
Background technology
Existing injection machine mould ejects and generally adopts O type solenoid directional control valve to control, and without any protection on hydraulic circuit, if injection machine matched moulds under mold ejection mechanism does not fall back on a situation, cannot realize ejecting mechanism rollback, can cause the damage of mould.
Utility model content
Technical problem to be solved in the utility model is above-mentioned deficiency in order to overcome prior art and provides a kind of injection machine mould to eject protective loop, can protect mould.
The utility model solves the problems of the technologies described above adopted technical scheme:
Injection machine mould ejects protective loop, it is characterized in that: comprise ejection cylinder, solenoid directional control valve and overflow valve, and ejection cylinder top is moved back between chamber and oil return line and arranged solenoid directional control valve, and ejection cylinder ejects between chamber and oil return line and arranges overflow valve.
Compared with prior art; the utility model has the advantage of: owing to being provided with the mould ejection protective loop of solenoid directional control valve and overflow valve composition; if injection machine is matched moulds under mold ejection mechanism does not fall back on a situation; top can be realized and move back chamber by solenoid directional control valve repairing, eject chamber by overflow valve oil return, realize ejecting mechanism rollback; play the effect of protection mould; therefore, it can realize the stop of ejecting mechanism in any position, can protect again the safety of mould.
Accompanying drawing explanation
Fig. 1 is hydraulic schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is further described.
As shown in Figure 1, in mould ejection protective loop, solenoid directional control valve V1 and overflow valve V2 forms mould ejection protective loop, and it is for mould ejection action control, can adjust suitable overflow valve V2 pressure according to mould.
When the electromagnet D1 of solenoid directional control valve V1 obtains electric, pressure oil P acts on ejection cylinder rodless cavity (ejecting chamber) through solenoid directional control valve V1, and the oil of ejection cylinder rod chamber (chamber is moved back on top) gets back to fuel tank through V1, realizes ejecting action; During the electromagnet D2 of solenoid directional control valve V1, pressure oil P acts on ejection cylinder rod chamber through solenoid directional control valve V1, and the oil of ejection cylinder rodless cavity gets back to fuel tank through V1, realizes top deactuate and does.
If injection machine is matched moulds under mold ejection mechanism does not fall back on a situation; the Median Function of ejection cylinder rod chamber by solenoid directional control valve V1 can be realized from fuel tank repairing; the oil of ejection cylinder rodless cavity gets back to fuel tank by overflow valve V2; realize ejecting mechanism rollback, play the effect of protection mould.
