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： An apparatus for driving a displaceably mounted component of an injection molding machine has at least one rotatably mounted crank which is driven by a motor. The crank drives the displaceably mounted component by way of a bar pivotably connected to the crank, the bar engaging a tiltably mounted intermediate lever which, in turn, is connected to the displaceably mounted component. The intermediate lever is mounted tiltably by way of an additional bar. The additional bar is pivotably mounted to be fixed with respect to the frame of the injection molding machine and is pivotably connected to the intermediate lever.

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

摘要翻译：一种用于在注射成型机中通过喷射器精确地确定模制品与模具的分离力的方法和装置。在模具中没有产品模制的情况下，施加在喷射器机构上的负载由喷射器机构的内部阻力构成。内部阻力包括在排出器机构内产生的摩擦力和弹簧的弹力，用于将顶针返回到其缩回位置。另一方面，在模具中模制的产品的操作中施加在喷射器机构上的负载由模制产品与模具的内阻和分离力构成。因此，在每个喷射器位置驱动具有和不具有模制产品的喷射器机构中检测到的负载之间的差异精确地表示模制产品与模具的分离力。基于所确定的成型品的分离力，更精确地进行对成型品的缺陷性/非缺陷性的判断，注射成型操作和喷射器机构的异常。

摘要： An actuating drive for a plasticizing unit of an injection molding machine is disclosed. The actuating drive includes a spindle drive with an electric motor and a control mechanism. An energy storage device is coupled with the spindle drive for force transmission therebetween. The energy storage device is loaded by the spindle drive in a return stroke phase and is unloaded in a forward feed phase, boosting the power of an electric motor. The actuator drive can be used, for example, for pulsating actuation of a mold ejector of the injection molding machine, significantly reducing the electrical energy consumption compared to conventional drives.
