Abstract
Disclosed, amongst other things, is: (i) a valve (220, 320, 420, 520, 620) for controlling air flow in an air pressure channel (354, 454) of a molded article holder (50, 150, 250, 350, 450); (ii) a molded article holder (350, 450) co-operable with the valve (220, 320, 420, 520, 620); and (iii) a post-mold holding device (315, 415) including the molded article holder (350, 450) and valve (220, 320, 420, 520, 620).
Claims37
A valve for controlling air flow in a molded article holder, the valve comprising:
- a body defining a valve chamber for movably receiving a valve element, the valve chamber having a device portal and a plenum portal, the device portal being spaced apart from the plenum portal, in a direction of travel of the valve element;
- the body defining a plenum, the plenum portal being defined by overlap-connected sidewalls of the valve chamber and plenum, the valve chamber being fluidly connected to the plenum through the plenum portal;
- the plenum portal configured to be longer than the valve element, in the direction of travel of the valve element, and the plenum portal configured to retain the valve element in the valve chamber, at least in part.
A molded article holder, comprising:
- a body defining a cavity for receiving the molded article, a pressure channel in the body extending into the cavity for affecting a pressure induced mobility control of a molded article with respect to the cavity;
- and
- a valve for controlling air flow in the pressure channel, the valve comprising:
- a body defining a valve chamber for movably receiving a valve element, the valve chamber having a device portal, connectable to the pressure channel, and a plenum portal, the device portal being spaced apart from the plenum portal, in a direction of travel of the valve element;
- the body defining a plenum, the plenum portal being defined by overlap-connected sidewalls of the valve chamber and plenum, the valve chamber being fluidly connected to the plenum through the plenum portal;
- the plenum portal configured to be longer than the valve element, in the direction of travel of the valve element, and the plenum portal configured to retain the valve element in the valve chamber, at least in part.

A post-mold holding device, comprising:
- a molded article holder, comprising:
- a body defining a cavity for receiving the molded article, a pressure channel in the body extending into the cavity for affecting a pressure induced mobility control of the molded article with respect to the cavity;
- and
- a valve for controlling air flow in the pressure channel, the valve comprising:
- a body defining a valve chamber for movably receiving a valve element the valve chamber having a device portal, connectable to the pressure channel, and a plenum portal, the device portal being spaced apart from the plenum portal, in a direction of travel of the valve element;
- the body defining a plenum, the plenum portal being defined by overlap-connected sidewalls of the valve chamber and plenum, the valve chamber being fluidly connected to the plenum through the plenum portal;
- the plenum portal configured to be longer than the valve element, in the direction of travel of the valve element, and the plenum portal configured to retain the valve element in the valve chamber, at least in part.
