发明名称 Forming a mold for steel casting
摘要 <p>FORMING A MOLD FOR STEEL CASTING A method of forming a mold for use in the casting of a steel railway freight car truck component is provided. A cope mold is formed by providing a near net shape oversize impression (12) of a cope pattern (14) of a product to be cast in a flask (10). A cope pattern of the product to be cast is then placed on the flask forming a spacing between the cope pattern (14) and the oversize impression (12). A resin coated sand is then blown to form a sand layer (16) between the oversized impression in the flask and the cope pattern. The resin sand is set to form a mold of a thickness between the oversized impression in the flask and the cope pattern of the product to be cast. The drag mold is formed in a similar manner.</p>
