Beschreibung
Zusammenfassung:The device includes: a runner block arranged at a position close to the injection port for resin material for secondary forming; and a slide core moved relatively with the runner block. In the runner block, a guide passage is formed which is communicated with a passage formed when pipe-shaped passages of the primary moldings are butted against each other. A heating medium passage or a resin material passage formed in the slide core are moved so that either the heating medium passage or the resin material passage can be selectively communicated with the guide passage formed in the runner block.
