PROBLEM TO BE SOLVED: To provide a blow molding method and apparatus in which a good deburring can be implemented while achieving a reduction in the cooling time.SOLUTION: Provided is a blow molding method and apparatus in which a foam blow molding is carried out within a mold, and in which the cooling efficiency is improved by positively bringing the burrs into contact with the mold, thereby improving the cooling efficiency of the burrs. The method for positively bringing the burrs into contact with the mold includes a method for bringing burrs into contact with mold by vacuum suction. Alternatively, the burrs may be brought into contact with the mold by a vacuum suction and an air blow.SELECTED DRAWING: Figure 8 |
