Problems solved by technology

[0008] However, in the above-mentioned conventional accumulator, since the above-mentioned lower limit value and upper limit value are fixed, when the actuator is driven at a low pressure, high-pressure oil is unnecessarily stored in the accumulator, and the oil pressure is applied. The load of the pump becomes higher correspondingly, and the energy consumed increases

Abstract

The invention provides a molding machine and a molding method which are capable of reducing a load imposed on an oil pressure supply source and reducing energy consumption. The molding machine comprises an actuator driven by being supplied with oil, an accumulator disposed in an oil passage for supplying oil to the actuator, a driving pressure detector for detecting the driving pressure for driving the actuator, a charge pressure detector for detecting the charge pressure for the accumulator, and a charge pressure setting processing means for setting the charge pressure on the basis of the detected charge pressure and detected driving pressure. In this case, since the charge pressure is set on the basis of the detected charge pressure and detected driving pressure, the possibility of oil of unnecessarily high charge pressure being accumulated in the accumulator is eliminated. Therefore, the load imposed on the oil pressure supply source is reduced by an amount corresponding thereto, thus reducing energy consumption.

Description

technical field [0001] The present invention relates to a forming machine and a forming method. Background technique [0002] Conventionally, in a molding machine having a driving device operated by a hydraulic circuit, such as an injection molding machine, heated molten resin is injected into a heating cylinder at high pressure, filled into the cavity space of a metal mold device, and made to flow in the cavity. Cool and solidify in space to obtain molded products. [0003] For this reason, the above-mentioned injection molding machine has a mold clamping device and an injection device. The above-mentioned mold clamping device has a fixed platen and a movable platen. By driving the mold clamping cylinder, the movable platen advances and retreats to perform mold closing, mold clamping, and And mold opening. [0004] On the other hand, the injection device has a heating cylinder for heating and melting the resin supplied from the stocker, and an injection nozzle for injecti...
