摘要： An injection molding machine includes complementary mold members which cooperate to present a mold cavity in the shape of a clay pigeon or other articles. An injection passage leading to the mold cavity receives a slidable pin of smaller diameter than the passage. The pin has a tapered tip which, when the pin is extended by a power cylinder, seats in an outlet opening of the passage to block the opening in a manner to prevent the formation of a sprue on the part. The pin is heated along with a surrounding sleeve to maintain the material in the passage in a molten state and to assure proper release of the part from the mold. When the pin is retracted, molding material is able to flow around it, through the injection passage, and into the mold cavity.

摘要： A valve gated injection molding system having an elongated valve member with an integral electrical heating element received in each nozzle to provide additional heat. An actuating mechanism engages the rear end of the valve member to reciprocate it between a withdrawn open position and a forward closed position. The valve member has a head which projects rearwardly from the nozzle. The heating element has an external terminal which extends outwardly from the head through a slot in a mounting sleeve. Thus, access for connection of an electrical lead to the moving terminal is provided between the fixed nozzle and the fixed cylinder of the actuating mechanism.

摘要： This invention relates to an improved valve pin for a valve gating injection molding system. Heat transfer to the gate area is extremely critical in valve gating systems and this is even more so when new high density glass filled materials are being molded. Thus it is necessary to provide substantially increased and more uniform heat transfer to the gate area. Accordingly, the invention provides an improved valve pin having at least a portion of the valve pin adjacent the tip end being formed of an elongated hollow sealed tube which contains a vaporizable fluid under a partial vacuum. The back end of the tube receives heat from the surrounding heater cast to vaporize the fluid in the area. The vapor pressure establishes circulation of the vapor towards the cooler tip end of the tube. The energy required to evaporate a liquid is the latent heat of vaporization and this energy is released by the vapor when it condenses upon encountering a cooler portion of the tube as it moves towards the tip end. The condensed liquid then returns to the back end of the tube where it is again evaporated. Circulation may be very rapid to provide a very greatly increased rate of heat transfer along the tube and the temperature drop along the length of the tube is reduced to a minimum. This allows minimum injection pressures and valve pin forces to be used with consequent decreases in manufacturing and operating problems and expense.
摘要翻译：本发明涉及一种用于阀门浇注注塑系统的改进的阀销。在阀门浇口系统中，传递到浇口区域的热传导非常关键，当新的高密度玻璃填充材料被模塑时，这更是如此。因此，需要提供基本上增加和更均匀的热传递到栅极区域。因此，本发明提供了一种改进的阀销，其具有邻近尖端的阀销的至少一部分由细长的中空密封管形成，其在部分真空下包含可汽化流体。管的后端从周围的加热器铸件接收热量以蒸发该区域中的流体。蒸汽压力建立蒸气向管的较冷末端的循环。蒸发液体所需的能量是蒸发的潜热，并且当蒸汽在朝向尖端移动时遇到管的较冷部分时冷凝时，该能量被蒸气释放。冷凝的液体然后返回到管的后端再次蒸发。循环可以非常快速地提供非常大的沿着管传热的速率，并且沿着管的长度的温度降低到最小。这允许使用最小的注射压力和阀针力，从而导致制造和操作问题和费用的降低。
