Abstract

PURPOSE: To make it possible to hold surely a molding at a specific part of a mold when the mold is opened, by introducing a negative pressure between the molding and an adjoining face of a specific separating mold, and a positive pressure between the molding and an adjoining face of another specific split mold and thereby holding the molding at a specific split mold.
CONSTITUTION: When molding is completed and opening of a mold 1 is started, by evacuating from the portion of adjoining faces 14 by means of a negative pressure source 9, and sending air under pressure to a portion between adjoining faces 18 by means of a positive pressure source 15, then a molding 20 is attracted on a lower split mold 3 and a middle split mold 4, and the separation of an upper split mold 2 from the molding 20 can be promoted. When the molding 20 is separated from the mold 3 and 4, since the mold 4 is elevated by means of an elastic force of a spring 5 and a contacted part of the molds 3 and 4 is opened, a negative pressure is acted on the portion between the adjoining faces 14, and the molding 20 is attracted and held on the molds 3 and 4. Thereafter, opening of the mold 3 is carried out by pushing the mold 4 by means of a pushing jig 7 and so on, and the molding 20 is separated by means of a separating device and so on.
