20090053039 | Single Piece Nozzle Cover Design and Method of Manufacture - A blower wheel housing for an air conditioning system is formed of a single molded element having a base section and a nozzle section with included vanes having complex shapes. This is accomplished by employing a pair of mold core elements which together form a cavity into which a plastic material is injected to form the cover with its integral nozzle and vanes, and the mold core elements are then withdrawn in opposite directions but at an angle to the direction normal to the two mold core elements to thereby accommodate the complex shapes of the vanes. In one embodiment, the top wall of the nozzle is disposed at an acute angle to the longitudinal plane of the cover, and the mold core elements are also withdrawn in a plane that is parallel to this wall. | 02-26-2009 |
