摘要： An injection die with an early-returning apparatus includes a lower fixed plate; a plurality of padding blocks located in the lower fixed plate; a male die mounted on the padding blocks; a female die coupled with the male die; an upper fixed plate mounted on the female die; a draw core unit installed in the female die; a shaft seat unit located in a space between the padding blocks and mounted on the lower fixed plate; a restoration unit fixed on a shaft-fixing plate of the shaft seat unit and inserted into the male die and an early-returning apparatus mounted on the shaft seat unit and the upper fixed plate and inserted into the male die and the female die. The early-returning apparatus includes a restoration cannulation unit located on the shaft seat unit, a restoration guide bushing unit sleeved on the restoration cannulation unit and installed in the male die and a restoration pushing shaft unit fixed on the upper fixed plate and inserting into the restoration guide bushing unit and the restoration cannulation unit. The restoration cannulation unit has a plurality of baffle blocks pivotally installed in the top portion of the restoration cannulation unit. The restoration guide bushing unit has an enlarged head portion to engage with the male die and receive the baffle blocks.

摘要： An apparatus for periodically cooling injection mold has a cavity formed between a cavity insert and a core insert of the injection mold. The bottom of the cavity defines a perforation that extends and passes through a lower pushing plate. An ejector pin is received in the perforation. The bottom end of the ejector pin passes out of the lower pushing plate and is above the top surface of a lower fixed plate. A sensor switch that controls several electric valve actuators is located on the lower fixed plate and is below the ejector pin. The electric valve actuators control cooling liquid to flow into several cooling pipes that are configured in the cavity insert and the core insert respectively. A method for periodically cooling injection mold includes the steps of: closing the injection mold and pouring raw materials into the cavity to form a product; pushing the ejector pin downward along the perforation and the bottom of the ejector pin touching and pressing the sensor switch. The sensor switch is inducted, and further causes the electric valve actuators opened. The cooling liquid flows into the cooling pipes for cooling the injection mold. Then, liberate the bottom of the ejector pin away from the sensor switch when the product is taken out from the injection mold. Last, release induction of the sensor switch for causing the electric valve actuator closed correspondingly and for stopping the cooling liquid into the cooling pipes.
摘要翻译：用于周期性地冷却注射模具的装置具有形成在注射模具的腔插入件和芯插入件之间的空腔。腔的底部限定了穿过下推板的穿孔。顶针被接收在穿孔中。顶针的底端从下推板出来，位于下固定板的上表面之上。控制多个电动执行器的传感器开关位于下固定板上，并位于顶针下方。电动阀执行器控制冷却液体流入多个冷却管，分别配置在空腔插入件和芯插入件中。一种用于周期性地冷却注射模具的方法包括以下步骤：关闭注射模具并将原料倒入空腔中以形成产品; 沿着穿孔向下推动顶针，顶推杆的底部接触并按压传感器开关。传感器开关被引入，并进一步使电动阀门执行器打开。冷却液流入冷却管，以冷却注射模具。然后，当产品从注射模具中取出时，将顶针的底部释放出传感器开关。最后，释放感应开关感应器，使电动阀执行器相应地关闭，并将冷却液停止进入冷却管道。
