A gate insert () for a stack assembly in an injection molding machine having a gate () through which a melt of thermoplastics material enters a mold cavity (). The gate insert has a cooling channel () surrounding, and substantially uniformly spaced from, the gate (). The cooling channel has an inner surface with a profile substantially parallel to the gate. The cooling channel is further defined by a two-piece gate insert having interconnecting surfaces ().

Gate cooling structure in a molding system

A gate insert () for a stack assembly in an injection molding machine having a gate () through which a melt of thermoplastics material enters a mold cavity (). The gate insert has a cooling channel () surrounding, and substantially uniformly spaced from, the gate (). The cooling channel has an inner surface with a profile substantially parallel to the gate. The cooling channel is further defined by either a structural insert in the form of a split ring () or by a recess () in a two-piece gate insert having interconnecting surfaces ().

The present invention relates to an improved method and apparatus for injection molding and cooling molded articles such as preforms so as to avoid crystallinity. The apparatus and method make use of a take-off plate for removing articles from a mold, which plate may include heat transfer devices for cooling exterior surfaces of the molded articles or preforms, and a system for cooling in a controlled manner interior surfaces of the molded articles or preforms.

Post-mold cooling apparatus

A method and apparatus for handling preforms from an injection molding machine whereby an array of molded articles received from the mold is reconfigured into a single row to assist in downstream auxiliary processing.

Post-mold cooling method

Preform post-mold cooling method and apparatus

A method for continuous transferring of hollow plastic articles from a first station to a second station, wherein articles at the first station are arranged in a first number of N.sub.1 columns and wherein articles at the second station are arranged in a second number of N.sub.2 columns, and wherein N.sub.2 differs from N.sub.1 and equals N.sub.1 times x, x being either an integer greater than 1 or a fraction, includes the steps of: transferring a first batch of articles on a carrying member from the first station to an array of N.sub.2 columns on the holding member at the second station; advancing at least a portion of the articles on a first number of holding members from the second station toward the blow molding station and replacing the advanced first number of holding members with a corresponding second number of holding members; transferring a second batch of articles on the carrying member from the first station to an array of N.sub.2 columns on the holding member of the second station, including at least the second number of holding members; and advancing at least a portion of the articles on the second number of holding members from the second station toward the blow molding station.
