Abstract

In production of synthetic plastic molded parts, a sprue part is separated from the molded part by one displacing slider which cooperates with one limiting surface and displaces a sprue film from a sprue gap between a sprue passage and a mold nest, while an overflow part is separated from the molded part by another displacing slider which cooperates with another limiting member and displaces an overflow film from an overflow gap between the mold nest and an overflow passage.
