Abstract: A second mold is divided into a recess-side mold portion, which includes a recess, and a remaining mold portion in a sliding direction of a movable pin, while a size of a gap between the recess-side mold portion and the remaining mold portion is adjustable. The second mold is configured to execute a first-mold-closing operation for contacting the recess-side mold portion to the first mold and thereafter a second-mold-closing operation for contacting the remaining mold portion to the recess-side mold portion. A distal end portion of the movable pin is configured to be placed into a non-contacting state, in which the distal end portion of the movable pin is not in contact with the workpiece, at a time of executing the first-mold-closing operation. The distal end portion of the movable pin is configured to contact the portion of the workpiece at a time of executing the second-mold-closing operation.

Abstract: A method includes a first molding process and a second molding process performed repeatedly. The first molding process includes injecting resin into a first pair of molds, in which a first pair of divided pieces is formed and which is fitted together without an inner mold, to couple the first pair of divided pieces to form a first hollow article at an injection station. The second molding process includes (i) injecting resin into a third pair of molds, which is fitted together with one inner mold interposed therebetween, to mold a third pair of divided pieces at the injection station, (ii) taking out the first hollow article from the first pair of molds at a removing station, and (iii) removing another inner mold from a second pair of molds while leaving a second pair of divided pieces between the second pair of molds at the setup station.
