MOLDING IRREGULAR OBJECTS |
摘要 |
This invention relates to molding irregular hollow thermoplastic objects having irregular shapes and particularly those having non-straight line centerlines. A mold is provided which comprises a cavity having a shape of the object and being dividing into two half molds by non-planar interfacing parting surfaces containing such non-straight line centerline. The molds are adapted to be separated while maintaining the centerlines co-planar. Means are provided for inserting a parison between the open half-molds with the parison co-planar to the center lines and means are provided for closing the molds while maintaining this co-planar relationship. Accordingly, the parison may be inserted into the cavity without the need for manipulating the parison relative to the mold.
