    摘要： A hot runner system includes a having a cavity (18). Melt is fed from a source of melt into the cavity (18), and a valve (24) isolates melt in the cavity (18) from melt in the source. A plunger (34) within the cavity (18) is driven forward to inject melt in the cavity (18) into a mold cavity (26) at high pressure without significantly increasing the pressure of melt in the source. The plunger (34) optionally functions as both the plunger (34) and the valve (24) by opening and closing communication between the cavity (18) and the manifold (16) as it is rotated.

    摘要： By starting injection in an injection molding machine, resin pressure in front of a check valve (3,4) is raised, and a check ring (3) moves backwards. Pressure of resin (8) accumulated between flights (5) of the injection screw (1) prevents the check ring (3) from moving backwards, and the screw (1) is kept freely rotatable to thereby make the backward speed of the check ring (3) faster. Therefore, the check ring (3) is brought into tight contact with a check seat (4) quickly to close the resin path. Thereafter, the rotation of the screw (1) is fixed, and reduced pressure in the injection/dwell stages causes the screw (1) to rotate in a normal direction, and prevents the resin (8) from being pressed toward the front of the check valve (3,4).

    摘要： In an injection molding machine, an ejection is conducted according to at least one of a speed control and a pressure control, until a load is reduced from the start of the ejection. After the load has been reduced, the ejection attended by a very small vibration is conducted. When the ejection is conducted according to the speed control, the deformation of a molded product as a result of the ejection by the ejector pin is reduced, leading to a reduced deformation restoring force. Thus, it is possible to prevent the molded product from being scattered and/or to prevent cracks from being produced in the molded product. In addition, it is possible to release the sticking of the molded product due to the biting of the ejector pin into the molded product, thereby eliminating a time loss and providing an improved efficiency of operation. Each of the speed control and the pressure control is conducted in correspondence to a load. After the ejection attended by the very small vibration has been performed, the ejector pin can be further advanced to effect the ejection. A resisting force can be generated, when the ejector pin is retreated.

    摘要翻译： 在注射成型机中，根据速度控制和压力控制中的至少一个进行喷射，直到从喷射开始减少负载。 负载降低后，进行非常小的振动的喷射。 当根据速度控制进行喷射时，由于顶针的喷射而导致的模制品的变形减小，导致变形恢复力降低。 因此，可以防止模制品在模制产品中被散射和/或防止产生裂纹。 此外，由于顶针被咬入模制品，可以释放模制产品的粘着，从而消除时间损失并提供更高的操作效率。 速度控制和压力控制各自对应于负载进行。 在通过非常小的振动进行喷射之后，可以进一步推进顶针以实现喷射。 当顶针退回时，可产生抵抗力。

The actuator (38) further has an extending rod (90) connected to the movable part (99) thereof and a block (92) connected to the rod (90), the block (92) being movable with the moveable part (99) of the actuator (38). A pivoting linkage element (36) is rotatably connected to the block (92) of the actuator and is connected to the valve pin of the nozzle.

    摘要： A motor is driven in a state where the moving platen (22) of an injection molding machine is not mounted with a mold to protrude an ejector rod (27), and the driving current of the motor is measured for each predetermined protrusion position. Then, the moving platen (22) is mounted with a mold (28b) and the motor is driven to protrude the ejector rod (27), and the driving current of the motor is measured. It is determined that an ejector rod protrusion position where a difference between this measured current value and a current value stored in a data table becomes larger is the protrusion start position of an ejector pin.
