摘要： The invention relates to a plastifying unit for an injection moulding machine, comprising a lift drive in the form of an electromotive spindle drive (11) and an associated working memory (22) which is loaded by means of the spindle drive in the return stroke phase and unloaded in the advance phase under power amplification of the electric motor (17, 18). According to the invention, the electrical energy consumption is reduced by the fact that the spindle drive contains a control mechanism (21) which acts between one of the drive elements (18) and a stationary housing element (14) of the spindle drive, parallel to the working memory, and which modifies the effective actuating force of the working memory according to the lift position of the spindle drive, said control mechanism being embodied in the form of a force coupling which can be regulated in a modifiable manner.

摘要： The invention relates to an injection moulding machine comprising a lift drive in the form of an electromotive spindle drive (1, 9) and a working memory which is associated thereto, is loaded by means of the spindle drive in a displacement phase of the same, and is unloaded in another displacement phase, under power amplification of the electric motor (9), especially for the pulsating actuation of the ejector (2). According to the invention, the electrical energy consumption of the spindle drive is significantly reduced by the fact that the working memory consists of two pressure spring arrangements (15, 16) which actuate the spindle drive in opposite directions and which are compensated in terms of force at a distance to the lift end positions of the spindle drive.

摘要： An electric actuator that is structured simply, low in costs and high in both energy efficiency and operation accuracy and is capable of realizing frequent activation and stop is provided. In a return stroke in which a linear actuator is in low load operation state, an energy generated by an electric motor and a kinetic energy generated by movable portions when they stop are absorbed and accumulated by a coil spring. By this constitution, it becomes possible to cause the movable portions of the linear actuator to quickly stop while eliminating the necessity of giving a braking force by an electric or mechanical brake or the like and of providing a configuration designed for giving a braking force in a reliable manner such as one provided as a measure against heat generation. On the other hand, in an actuation stroke, the energy accumulated in the spring is released as operation energy of the movable portions when the spring extends and a driving force required of the electric motor is reduced.

摘要： A method of and an apparatus for precisely determining a separating force of a molded product (3) from a mold (2a) by an ejector in an injection molding machine. A load exerted on an ejector mechanism (9-12) in operation without a product (3) molded in the mold (2a) is constituted by an inner resistance of the ejector mechanism (9-12). The inner resistance includes frictional force produced within the ejector mechanism (9-12) and resilient forces of springs (12) for returning ejector pins (11) to retracted positions thereof. On the other hand, the load exerted on the ejector mechanism (9-12) in operation with a product (3) molded in the mold (2a) is constituted by the inner resistance and the separating force of the molded product (3) from the mold (2a). Thus, a difference between the loads detected in driving the ejector mechanism (9-12) with and without a molded product (3) at each ejector position precisely represents the separating force of the molded product (3) from the mold (2a). Judgment on defectiveness/ non-defectiveness of the molded product (3), and abnormality of the injection molding operation and the ejector mechanism (9-12) are performed more precisely based on the determined separating force of the molded product (3).
