ABSTRACT:
A retainer for use in connection with injection molding that is used to retain a slide in its open position when the mold is opening. The retainer has two pivotally connected jaw members and a coiled compression spring that applies spring pressure to the jaw members as these members engage a pin that is connected to a slide when the mold is opening. The construction of the jaw members avoids undesired spreading when the pin engages the jaw members and the jaw members are constructed in a manner that enables the retainer to be easily assembled. The retainer jaw members completely surround the coil spring and protect it from dirt and only a portion of the ends of the coil spring exert a force upon the jaw members when the retainer is in use.
