Abstract

PURPOSE:To easily and safely produce any shape of moldings by blow molding method by providing an adsorptive block having a ventilability and a vacuum suction path leading to the block for one of split type paired molds. CONSTITUTION:When actuating a vacuum device, air is sucked up in the direction of arrow from an adsorptive block 13 through a vacuum suction path 12 to produce a suction force in the block 13. Then, a parison 14 of a given length is hung down from a parison former, and the lower part of the parison 14 is once matched with the shape of the hollow 16 of molds 15 by lifting it by hand, whereupon the block 13 holds the parison 14 by its suction force. Then, hand is separated from the parison 14. Afterwards, the molds are clamped, air is blown into the parison 14 to press it on the hollow 16 in order to mold it into a shape of product.
