Existing hydraulic injection molding machine system ubiquity problems, for example: complex structure, energy consumption is big, system's caloric value is big, and clamp force is not enough etc., in order to respond the call of low-carbon (LC), just be badly in need of a kind of simple in structurely, energy consumption is little, the rain boots hydraulic injection molding machine system that system's caloric value is little.
Summary of the invention
The purpose of this utility model is to provide a kind of rain boots hydraulic injection molding machine system, and this hydraulic system aims at produces the rain boots design, oil channel structures compactness, simple not only, and system's caloric value is little, and injection moulding is steady, and reliable operation has enough clamp forces.
Of the present utility model being characterised in that: a kind of rain boots hydraulic injection molding machine system, comprise fuel tank, the oil pump of at least one, injection hydraulic cylinder, folding mould hydraulic cylinder and locked mode hydraulic cylinder, it is characterized in that: the hydraulic oil oil-out of described oil pump (A) leads to the locked mode hydraulic cylinder behind Y type 3-position 4-way solenoid directional control valve, the hydraulic oil oil-out of described oil pump (B) is respectively through O type 3-position 4-way solenoid directional control valve (C), (D) lead to injection hydraulic cylinder and folding mould hydraulic cylinder after, be provided with normally closed two-position four-way solenoid directional control valve (E) between described folding mould hydraulic cylinder and the fuel tank, (F).
One input of above-mentioned normally closed two-position four-way solenoid directional control valve (F) also is connected with the hydraulic oil oil-out of oil pump (G), the also other pilot-type relief valve (I) that is connected to of the hydraulic oil oil-out of described oil pump (G).The also other pilot-type relief valve (J) that is connected to of described oil pump (A) hydraulic oil oil-out.The turnover oil pipe line of described locked mode hydraulic cylinder is provided with hydraulic control one-way valve.The turnover oil pipe line of described folding mould hydraulic cylinder is provided with unidirectional flow speed control valve.Be provided with the check valve of often driving the two-position four-way solenoid directional control valve and leading to the hydraulic oil oil-out of oil pump (A) between described oil pump (A) and oil pump (G) the hydraulic oil oil-out.Described oil pump (B) is provided with excess flow control.Also be provided with the overflow pressure-reducing valve between described oil pump (B) and the O type 3-position 4-way solenoid directional control valve (C).Described hydraulic system has intelligent controller control.
Advantage of the present utility model: the one, frame for movement is simple, and is reasonable in design, and system energy consumption is little, and caloric value is little; The 2nd, have enough mold clamping forces, molten plastic injects die cavity with the high pressure of 120～200MPa, on closed mould, can produce very big mould opening force, so the closing liquid cylinder pressure must produce enough mold clamping forces, guarantee locking to the mould after the closure, otherwise mould can produce the slit and make the excessive limit of plastic products generation during injection moulding, waste product occurs; The 3rd, system works is stable, reliable, and noise is little, has high use value.
