Abstract
A machine for compression molding plastic articles includes an array of compression molds mounted on a support for movement through a defined mold path. A cam is disposed adjacent to the support to engage the molds in sequence and move at least one segment of each mold between open and closed positions. The cam has a first portion for opening the molds, a second portion for closing the molds in sequence and a pivot mounting the second cam portion to the first cam portion. A latch holds the second cam portion in a first position for closing the molds in sequence, and is responsive to excess force on the second cam portion to release said second cam portion to pivot to a second position spaced from the path.
