Subsequently, a molten parison P is suspended from a die 2 and pinched at the lower part thereof to be continuously suspended to the gap between mutually separated male and female molds 8a, 8b. Low pressure air is blown into the parison from a preblow pin 18 to be preparatorily inflated while the parison is held between the upper and lower side wall members 10a, 10b. At the same time, the upper and lower side wall members of the female mold are closed while the male and female molds are allowed to gradually approach the parison and the parison is allowed to follow the cavity formed by the male and female molds between the fixed side wall members on the lateral side of the parison while the side wall members on the side of the parison are gradually advanced.

摘要： PURPOSE:To easily eliminate a blow pin mark by heating and melting the protruding top part of a hollow molded product having a blow pin hole generated so as to follow a conical part to flatten the same under pressure. CONSTITUTION:A parison 4 is conformed even to the recessed part of the cavity 5 of a male mold 3 by the pressure of the gas fluid introduced into the parison 4 and a molded product has the protruding part 20 formed corresponding to the recessed part and the mark 17 of a blow pin 7 is left after the blow pin 7 is inserted in the parison 4. When the blow pin mark 17 of the protruding part 20 is locally melted and pressed under heating by a heated electric iron 18, the protruding part 20 is deformed to be flattened and the blow pin mark 17 is eliminated. In the elimination of the blow pin mark 17, a high frequency heater is used according to circumstances in place of the electric iron 18.

摘要： PURPOSE:To make the wall thickness of a blow molding constant by advancing a tack-off core while preliminarily expanding the parison suspended from a die during the mold clamping operation of female and male molds to perform molding. CONSTITUTION:In a blow molding machine 1, both molds 8a, 8b are set to an opened state and a parison P having a circular cross section is suspended to be stopped and the mold clamping cylinder attached to the outside of the left and right molds 8a, 8b is operated to perform mold clamping. The tack-off core 12 having retreated in the direction of the female mold 8b is allowed to quietly advance simultaneously with mold clamping. Further, the tack-off core 12 is allowed to advance during mold cramping operation while the parison is preliminarily expanded by introducing pre-blow air into the parison. By this constitution, the parison P follows the surface of a cavity accompanied by mold clamping and, even when the introduction of blow air and the cooling of the mold 8 are performed in this state, the parison is not locally reduced in wall thickness and a molding 10 with definite wall thickness can be obtained.

摘要： PURPOSE:To provide a heat insulating mold for blow molding, the temperature of which can be controlled uniformly irrespective of the shape of a cavity and with which molding cycle can be improved. CONSTITUTION:By the constitution containing porous sintered metal layers 16 along the cavity 12 of a mold 14, any heat insulating layer suitable for shape, even complicated, is produced by utilizing the high formability of sintered material. Otherwise, by providing resin layer on the surface of the cavity 12, double- layered heat insulating layer is formed, resulting in realizing the mold structure having high heat insulating function. Further, through heat exchanging medium passages formed by utilizing the pores 18 within the sintered metal, refrigerant produced with a cooling device is circulated within the sintered metal layer 16.
