Abstract
A blow molding apparatus comprising a wheel mounted rotationally on a base for rotating a plurality of molds past an extrusion die. The wheel is comprised of a hub mounted to a rotational shaft and a plurality of disk segments mounted about the hub to carry the plurality of molds. The disk segments may be individually selectively secured to the hub to facilitate simple replacement of disk segments.
Claims23
A blow molding apparatus comprising:
- a wheel configured to rotate about a rotational axis, the wheel comprising:
- a hub mounted on the rotational shaft;
- and
- a disk comprising a plurality of disk segments for carrying a plurality of molds, the disk segments being selectively removable from the hub;
- whereby the plurality of molds are disposed around the rotational axis of the wheel.
A wheel for a blow molding apparatus, comprising:
- a hub for mounting on a rotational shaft of the apparatus, the hub defining a rotational axis of the wheel;
- and
- a disk comprising a plurality of disk segments for locating a plurality of molds about the rotational axis, the disk segments being selectively removable from the hub.
A discrete disk segment of a continuous rotary extrusion blow molding apparatus configured to associate with one or more other discrete disk segments to form a disk of the blow molding apparatus, the discrete disk segment comprising:
- a hub abutment end;
- an upper end configured to constitute a portion of the disk perimeter;
- opposing sides configured to be disposed adjacent to opposing sides of the one or more other disk segments;
- and
- a groove configured to locate the disk segment with respect to the one or more other disk segments.
A continuous rotary extrusion blow molding apparatus comprising:
- a wheel configured to rotate about a rotational axis, the wheel comprising:
- a hub mounted on the rotational shaft;
- and
- a disk mounted to the hub, the disk comprising a plurality of discrete disk segments for carrying a plurality of molds, each of the plurality of discrete disk segments comprising opposing sides with each opposing side being disposed adjacent to the opposing side of an adjacent discrete disk segment;
- whereby the plurality of molds are disposed around the rotational axis of the wheel.
