摘要: The present invention relates to an apparatus for injection molding a thin-walled plastic article with substantially equal thickness sidewalls, a base portion, and a lip portion. The apparatus includes a two part mold arrangement in which a first part defines has a mold cavity and a second part defines a mold core. The first and second mold parts in a mold closed position define a mold space in the shape of the article being molded. The apparatus further includes two or more gates adjacent a lip portion of the mold space for injecting molten plastic material into the mold space and a bottom center venting arrangement. The apparatus further includes a restriction in the mold space for improving the operation of the bottom center venting arrangement and providing a more balanced filling in a multi-cavity molding machine.

摘要: Apparatus includes a mold cavity and a molten plastic inlet channel for communication with the mold cavity for transmission of molten plastic to the mold cavity. A valve stem is provided with substantially no net resulting forces on the valve stem due to melt pressure acting on the projecting area of its upstream and downstream faces.
