摘要： An injection molding shutoff assembly that includes a chamber containing a movable body movable between rear and forward positions. In the rear position, the movable body provides a seal and prevents flow of molten plastic out the chamber inlet, called drool. When the movable body is in the forward position, one or more passages permit flow of the molten plastic around the movable body and to an exit in the chamber, leading to one or more molds. In an alternate embodiment, the apparatus also includes an elongate stem that maintains the movable body in the forward position allowing the injection molding system to decompress, thereby eliminating drool and decreasing downtime.

摘要： The present invention provides an injection molding method which intends to lower a mold clamping force in view of both of a projected area of a molded article and an injection pressure, and contributes to an energy saving and a reduction in a cost of equipment and a manufacturing cost. In a cavity (13) formed in a metal mold (5) for an injection molding, there are arranged a first gate (21) injecting a first molten resin (101) anteceding in one end side (a charging start side) in a longitudinal direction, and a second gate (22) injecting a second molten resin (102) following in another end side (a charging finish side). The second molten resin (102) is newly injected from the second gate (22) before a fluid head portion of the first molten resin (101) injected from the first gate (21) reaches a position of the second gate (22). Further, the first molten resin (101) becomes in an approximately cooled and solidified state by the time when the second molten resin (102) reaches a terminal end in the charging finish side within the cavity (13).

摘要： A nozzle contact device of an injection machine has an injection device, a nozzle, a flexible body, a tension buffer device and a tension-measuring device. The nozzle is installed a front side of the injection device. The flexible body is used to drive the injection device to contact or separate from a mold. The tension buffer device is installed at a lateral side of the flexible body, and has an elastic body for receiving tension from the flexible body and decomposing the tension to form a component force and a displacement. The tension-measuring device is used to measure the displacement of the tension buffer device and deciding a contact force between the nozzle and the mold.

摘要： A nozzle touch mechanism which does not allow an injection unit to move back by the force of inertia at the time of acceleration of injection and prevents leakage of the molten resin. A damper is arranged between the injection unit and a stationary platen secured to a base, so as to generate a strong braking force only at the time of high acceleration of the injection unit. A ball screw is rotated by driving an electric motor to move forward a nut member screwed onto the ball screw, whereby the injection unit is moved via a spring. When the injection unit is stopped by contacting a nozzle to a metal mold, the spring is contracted. When the amount of contraction of the spring reaches a predetermined value, the motor is stopped and locked such that the nozzle touch force corresponding to the amount of contraction of the spring is generated. Even though the injection unit undergoes the force working to move back the unit due to the inertia force at the time of acceleration of the injection, the injection unit is not moved back because the damper substantially prevents the movement back of the unit and the leakage of molten resin.
摘要翻译：喷嘴接触机构，其不允许注射单元在加速注射时通过惯性力向后移动，并防止熔融树脂泄漏。在注射单元和固定在基座上的固定的压板之间设置阻尼器，以便仅在注射单元的高加速度时产生强的制动力。通过驱动电动机使滚珠丝杠旋转，使拧入滚珠丝杠的螺母部件向前移动，由此通过弹簧移动注射单元。当注射单元通过使喷嘴与金属模具接触来停止时，弹簧收缩。当弹簧的收缩量达到预定值时，马达停止并锁定，从而产生与弹簧的收缩量对应的喷嘴接触力。即使注射单元由于注射加速时的惯性力而经受力作用以移动单元，所以注射单元不会向后移动，因为阻尼器基本上防止了单元的运动和泄漏熔融树脂。
