摘要:
An injection control apparatus includes an injection member; a drive section for injection; an injection-speed detection processing section which detects injection speed; an injection-pressure detection processing section which detects injection pressure; and a drive control processing section which drives the drive section for injection on the basis of the injection speed and the injection pressure to thereby perform pressure control before start of charging of a molding material into a cavity, and speed control after the start of charging of the molding material into the cavity. Since the drive section is driven on the basis of the injection speed and the injection pressure such that pressure control is performed before start of charging of a molding material into a cavity, and speed control is performed thereafter, the pressure of the cavity after the molding material has entered the cavity becomes stable and uniform.

摘要:
A control system for an injection molding machine performs a molding cycle. The molding cycle includes a filling process for controlling an advancing motion of a screw of the injection molding machine, and a hold press process for controlling a pressure of a molten resin after the filling process. The control system includes retracting speed limit means for limiting a retracting speed of the screw to a predetermined retracting speed limit value after a pressure control in the hold press process begins.

A refrigeration unit is provided without impairing freshness, as before thawing, after thawing frozen subjects, and, with providing excellent color of dark colored flesh of fish/meat, especially in the case of using perishable food, such as meat or fish, for subjects to be frozen. A core unit for a refrigerator, between a substantially-rectangular first plate member and a substantially-rectangular second plate member spaced apart and arranged in parallel toward each other, where an electric wave is propagated to the sides of the first plate member and the second plate member by an electric wave transmission antenna, and that can form a unidirectional and substantially-uniform static magnetic field in substantially-normal directions of a principal surface of the first plate member and a principal surface of the second plate member, is used.
摘要:
An injection pressure of an injection molding machine is controlled by a movement of a screw. The injection pressure is detected when the screw is moved forward and rearward in an injection process. A rising injection pressure ΔP is predicted in a case where the screw is stopped at a previously set deceleration of the screw from the time of detection of the injection pressure. The predicted rising injection pressure ΔP and a previously set pressure P are compared, and the screw is decelerated at a previously set deceleration based on the comparison result.

An injection molding machine includes an actuator supplied oil so as to actuate, an accumulator in which the oil, supplied to the actuator and having an accumulating hydraulic pressure set in a range of designated values, is accumulated, an accumulating hydraulic pressure determining part configured to determine whether or not the accumulating hydraulic pressure is sufficiently higher than an actuating hydraulic pressure that is a hydraulic pressure for actuating the actuator, and an accumulating hydraulic pressure change part configured to reduce a set value of the accumulating hydraulic pressure in a case where the accumulating hydraulic pressure is sufficiently higher than the actuating hydraulic pressure.
