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.

Mold for plastic bottles

The invention relates to an apparatus for feeding labels to a mold for plastic parts. An object of the invention is to having a pair of tie bars associated therewith for opening and closing the mold, can feed into the mold cavity labels larger than conventional labels, can also feed labels to various molds having different sizes and different heights, and which is also arranged such that the label-attachment locations and the position of labels relative to a mold can be changed when the labels are attached. To achieve this object, the label feeder has a base frame whose height is adjustable relative to the floor on which it is mounted, a generally rod-shaped loader swingably mounted on the base frame, a longitudinally expandable expansion element adjustably mounted on the loader, on arm mechanism mounted on the front end of the expansion element and having a front end structure which can be laterally opened and closed, a label sucking device attached to the front end of the arm mechanism, and a parallel linkage connecting device for feeding the labels in a parallel manner with respect to parting surfaces of the mold when the arm mechanism is laterally opened and closed.
