Abstract

The utility model discloses an auxiliary mold moving oil way system of an injection molding machine, which comprises an oil inlet, an oil return port, an electro-hydraulic directional control valve, a first mold moving oil injection port and a second mold moving oil injection port, the oil inlet, the oil return port, the first mold moving oil injection port and the second mold moving oil injection port are respectively connected with the electro-hydraulic directional control valve, and a first safety control unit is arranged between the first mold moving oil injection port and the oil return port. And a second safety control unit is arranged between the mold moving oil injection port II and the oil return port. According to the auxiliary mold moving oil way system of the injection molding machine, the oil inlet, the oil return port, the mold moving oil injection port I and the mold moving oil injection port II are respectively connected with the electro-hydraulic directional control valve, the normal operation of the oil way is realized by the electro-hydraulic directional control valve, and when the electro-hydraulic directional control valve is stuck, if the left side position is stuck, the oil way pressure of the oil inlet is released by the second safety control unit, so that the oil way pressure is reduced. Otherwise, when the right side is stuck, the oil path pressure of the oil inlet is relieved by the first safety control unit, so that the safety of the auxiliary mold moving power is ensured, and the safety production of the injection molding machine is further realized.
