Abstract
The method comprises forming four like, and interfitting molds, with cavities therein, and closing all the molds together in envelopment of a cruciform element. The element, preferably, carries bearings on opposite ends of the pins or shafts thereof. Casting material, such as high tensile bronze is introduced into the molds cavities to cast the end product therein, onto the cruciform element and bearings. The method has particular application and utility in the casting of assemblies of articulatable components, such as universal joints, and the like, in that it affords the fabrication of such assemblies, complete, in a single casting operation. The casting means comprises a mold which is interfittable with others thereof for use in the practice of the above-noted method.
Claims9
A method of casting, in a single casting operation, an assembly of components which is articulatable in a plurality of axes, comprising the steps of:
- forming a first mold with cavities shaped to cast a partial cross-section and partial length of a first component of the assembly, and shaped to cast a first whole portion of a second component of the assembly;
- forming a second mold which is a mirror image of said first mold, the second mold having cavities shaped to cast a complementary cross-section and a same partial length of the first component, and in which to cast a second whole portion of said second component;
- forming third and fourth molds with cavities shaped to cast the remaining length of said first component, to complete said first component, and shaped to cast complementary cross-sections of said second component which will complement said first and second whole portions and complete said second component;
- forming an element with a plurality of transversely disposed pins or shafts;
- supporting said element against movement;
- closing said molds onto each other and in envelopment of said element;
- and introducing casting material into said cavities.
