摘要： An apparatus for placing mold charges into a mold of a compression molding machine includes at least one mold charge pick-up cup for receiving a severed charge of molten plastic, a vacuum source for applying a vacuum to the pick-up cup to retain the mold charge in the cup, and a source of gas (such as air) under pressure for periodically applying gas to the cup to release the mold charge from the cup. In one exemplary embodiment, the vacuum source applies a continuous vacuum to the cup, and the source of gas under pressure periodically applies gas to the cup to overcome the continuous vacuum at the cup. In another exemplary embodiment, vacuum and gas under pressure, are alternately applied to the cup. The vacuum source preferably includes a vacuum generator coupled to the source of gas under pressure for generating the vacuum to be applied to the cup. The vacuum source preferably includes a vacuum pump coupled to the source of gas under pressure for generating the vacuum to be applied to the cup. The source of gas under pressure preferably includes a valve for periodically applying gas under pressure to the cup. The apparatus preferably includes a carrier for moving the cup from a source of severed charges of molten plastic to the mold of the compression molding machine, with the cup, the vacuum pump and the valve preferably being mounted on the carrier. The vacuum source preferably includes a vacuum limiter that also is mounted on the carrier.

摘要： A compression molding apparatus includes a female mold half which receives a charge of molten plastic and a cooperating male plunger which compression molds the molten plastic into an article within the female mold half. A slide mold part is located between the male plunger and the female mold half. The slide mold part includes left and right slide mold halves which when brought into juxtaposition, define a central mold space. The left and right mold halves are slidable toward and away from each other, to form the central mold space and to open the central mold space respectively. The male portion is reciprocated downwardly to undertake the compression molding, and a cam mechanism is activated by the reciprocation to close the slide mold part during compression molding. The return stroke opens the slide mold part to allow removal of the molded article without stripping or unscrewing the molded article from the slide mold part. In an exemplary embodiment, a bottle-like container is formed by compression molding which includes a neck having an external thread. The external thread is formed in the central mold space of the slide mold part. The cam mechanism is arranged to open the slide mold part to release the threaded neck of the container for removal from the mold apparatus.
摘要翻译： 压缩成型装置包括：阴模半部，其接收熔融塑料的电荷;以及配合的阳柱塞，其将熔融塑料压缩成阴模半部内的制品。 滑动模具部分位于阳柱塞和阴半模之间。 滑动模具部件包括左右滑动半模，当并置时，其形成中心模具空间。 左半模和右半模能够相互朝向和远离地滑动，以形成中心模具空间并分别打开中心模具空间。 阳部向下往复运动以进行压缩成形，并且通过往复运动来激活凸轮机构，以在压缩成型期间闭合滑动模具部件。 返回行程打开滑动模具部件，以允许去除模制品而不从模具部件剥离或松开模制品。 在一个示例性实施例中，通过压缩成型形成瓶状容器，其包括具有外螺纹的颈部。 外螺纹形成在滑动模具部件的中心模具空间中。 凸轮机构被布置成打开滑动模具部分以释放容器的螺纹颈部以从模具装置移除。

摘要： Apparatus and method for the assembly of a two component home canning closure. One popular type of home canning closure utilizes a relatively thin lid to seal a jar with a threaded band holding the lid down. The gasket portion of the lid is relatively fragile. In the assembly of the two components in a manufacturing process for shipment to the consumer, the lids are handled gasket upmost the minimize possible damage. At an assembly station, the lids are rotated 180.degree. to present the gasket downward in the band for protection during shipment and storage.
