Abstract
Disclosed are a valve device and a blow molding system. The valve device is used in a blow mold and one or two decorative labels for affixing to a bottle body are placed in the blow mold. The valve device comprises a base and at least one pin arranged on the base, wherein the pin is inserted into a vacuum suction hole of the blow mold. The valve device opens the vacuum suction holes to create negative pressure and enable a decorative label to be adsorbed to the inner wall of the blow mold, and blocks the vacuum suction holes to achieve detachment between the decorative label and the inner wall of the blow mold, thereby adhering the decorative label to the bottle body to complete the production.
Claims9
A valve device operable to be used in a blow mold having an inner wall, an outer wall, and multiple vacuum suction holes, wherein a decorative label for affixing to a bottle body is placed in the blow mold, the valve device comprising:
- a base having a head end;
- and
- multiple pins that are evenly radially distributed around the head end of the base, wherein the multiple pins are configured to be inserted into the multiple vacuum suction holes of the blow mold, and
- wherein the base is operable to abut against or move away from the outer wall of the blow mold to facilitate the inner wall of the blow mold to release or adsorb the decorative label.
