Method for inserting pipe body as cast-in


PURPOSE: To reduce the cost of a product by simplifying the machining process for flowing passage at the time of forming the flowing passage in the inside of the die casting product. CONSTITUTION: Under the condition of opening dies 2, 4 for die casting, a pipe body 8 is placed and fixed in a prescribed position in the dies 2, 4. Successively, the dies 2, 4 fixed with the pipe body 8 are closed and molten metal is poured into the dies 2, 4 at high pressure. Therefore, the pipe body 8 is surely inserted with the molten metal under the condition of accurate positioning in the dies 2, 4 and the machining process for flowing passage is simplified and cost redution of the product is obtd.
