Abstract
Official abstract text for this publication.
A production apparatus includes the following stations juxtaposed in the following sequence: a parison forming station for forming a parison; a built-in part attachment station where opposite sides of a center die provided with a built-in part are held between a pair of molding dies to locate the center die in the molding dies with the parison between the center die and the molding dies, and the built-in part being attached to the parison transferred to the molding dies; a molding station where the molding dies are closed to mold the hollow molded product; and a conveyance station for taking the hollow molded product out of the molding dies and conveying the hollow molded product. The center die is fixed at the built-in part attachment station, and the molding dies are configured to be movable back and forth between the built-in part attachment station and the molding station.
First claim
Opening claim text (preview).
What is claimed is: 1. A production method for a hollow molded product, comprising: a parison carrying-in step of carrying a parison formed at a parison forming station along one direction to opposite sides of a single center die provided with a built-in part and installed at a fixed position; a built-in part attachment step in which the opposite sides of the center die are held between a pair of molding dies to locate the center die in the molding dies with the parison between the center die and the molding dies, the parison being supplied from the parison forming station and the parison being in a state before being transferred to the molding dies, and then the built-in part is attached to the parison transferred to the molding dies; a molding die movement step of moving the molding dies along the one direction to a prescribed position after the built-in part is attached; a molding step in which the molding dies are closed and the hollow molded product is molded at the prescribed position; and a conveyance step of conveying the hollow molded product taken out of the molding dies along the one direction.
