<p>MOLD FOR MANUFACTURING FLANGED OBJECTS WITHOUT SIDE ACTION Inventor: John W. Von Holdt An outer mold half and a mold core define as part of the mold cavity an annular chamber portion for receiving molding compound to form an outwardly projecting, relatively thick annular section in the molded object. Stripper means push newly formed molded objects out of intimate contact with the mold core. The diameter of a portion of the mold core across which the annular section is pushed by the stripper means is less than the diameter of the mold core portion against which the annular section is formed. Accordingly, the cooling, freshly molded annular section can shrink inwardly and be drawn out of the annular chamber portion, for removal from the mold without the need of side action.</p> |
