摘要： A blow molding apparatus having a mold clamping apparatus of the clam shell type, and having a linkage controlling the opening and closing of the mold, the linkage being comprised of two links pivotally connected to each other and driven by a pneumatic or hydraulic cylinder. The links are configured to provide the cylinder with mechanical advantage so that little mold separation force is recognized at the cylinder.
摘要翻译：一种吹塑设备，具有蛤壳型的模具夹紧装置，并且具有控制模具打开和关闭的联动装置，该联动装置由彼此枢转地连接并由气动或液压缸驱动的两个连杆构成。连杆构造成为气缸提供机械优点，使得在气缸处可以识别出小的分离力。

摘要： A blow molding apparatus comprising a wheel mounted rotationally on a base for rotating a plurality of molds past an extrusion die. The wheel is comprised of a hub mounted to a rotational shaft and a plurality of disk segments mounted about the hub to carry the plurality of molds. The disk segments may be individually selectively secured to the hub to facilitate simple replacement of disk segments.

摘要： A multilayer injection nozzle assembly, for use with an injection molding machine, to form a multilayer injection molded article comprising an inner nozzle, a middle nozzle and an outer nozzle. The inner nozzle has a first hole which communicates with a first channel in the inner nozzle and for receiving a flow of a first material from the injection molding machine. The inner nozzle also has a second hole which communicates with a second channel in the inner nozzle for receiving a flow of a second material from the injection molding machine. The first channel communicates with an inner and an outer channel in the inner nozzle, whereby the first material flows from the first channel into both the inner channel and the outer channel. The first material that flows into the inner channel will flow out of the nozzle assembly to form a first layer of the injection molded article and the material that flows into the outer channel will flow out of the nozzle assembly to form a second layer of the injection molded article.
摘要翻译：一种与注射成型机一起使用的多层注射喷嘴组件，以形成包括内部喷嘴，中间喷嘴和外部喷嘴的多层注射成型制品。内部喷嘴具有与内部喷嘴中的第一通道连通并且用于从注射成型机接收第一材料的流动的第一孔。内部喷嘴还具有与内部喷嘴中的第二通道连通的第二孔，用于从注射成型机接收第二材料的流动。第一通道与内部喷嘴中的内部通道和外部通道连通，由此第一材料从第一通道流入内部通道和外部通道。流入内部通道的第一种材料将流出喷嘴组件以形成注射成型制品的第一层，并且流入外部通道的材料将流出喷嘴组件以形成第二层注射模制品。
