摘要:
A molding machine is provided comprising a rotary type molding machine (1) having an injection molding portion (3) for molding a preform, an orientation blow molding portion (5) provided with a blow mold (13) which receives the preform directly or after being subjected to temperature control for molding the preform into a hollow container such as a bottle by means of an orientation blow device and, a molded product removing portion (6), and a label insertion device (20) provided adjacent the orientation blow molding portion (5). The label insertion device (20) comprises a label supply device (26) positioned to the side of the blow mold, a drive device for moving the label supply device (26) forward and backward with respect to the blow mold, and a label magazine (42) disposed between the label supply device (26) and the orientation blow molding portion (5).
摘要:
A mold for plastic bottles is designed to have an internal arithmetic average of roughness height of a cavity-forming wall to be less than 0.25 .mu.m. The mold has air passages for decompressing air in the cavity and absorbing the air between the wall and a parison expanded by blowing into it. The mold has air suction passages around the mouth portion of the mold and between the main body and the bottom portion of the mold. The surface of the bottle and the molds have so little air stagnated between the mold and the bottle wall that the resulting bottle results in a high gloss.
