Abstract
An injection molding machine in which a support on a base carries oppositely facing stationary mold portions which, when joined by movable mold portions, form a pair of mold cavities, one of which can be injected with a moldable material having a long solidification time, while the other contains a previously injected article which is solidifying and can be released as soon as the injection of the first cavity is completed. One of the movable mold portions is connected to a movable plate in a fixed spaced relationship, with a wedge-type locking mechanism between the plate and the other movable mold portion for the locking of both mold cavities simultaneously with a single locking mechanism.
