Abstract

PURPOSE:To manufacture a perfectly closed hollow body by blow molding, by drawing off a blow pin and push-contacting the opening part of the parison with a slide pin after blow molding the parison. CONSTITUTION:The parison 2 is closed in within the forming mold 5 and contacted to the inner wall of the forming mold 5 by blowing compressed air from the blow pin 3. At the same time the parison 2 around the blow pin 3 is heat- fused, then the blow pin 3 is drawn off and the heat-fused part is push-contacted by the slide pin 9. Thus, the perfectly closed hollow body like a float is manufactured by using blow molding alone.
