JOINING STRUCTURE OF DIE-CAST MOLD

PROBLEM TO BE SOLVED: To obtain the joining structure of a die-cast mold for favorably joining die-cast mold members faced to each other with an adhesive. SOLUTION: A joining surface 3 is formed on the connection part 1b of a die-castmold member 1 and a joining surface 4 consisting of a projected su...

Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain the joining structure of a die-cast mold for favorably joining die-cast mold members faced to each other with an adhesive. SOLUTION: A joining surface 3 is formed on the connection part 1b of a die-castmold member 1 and a joining surface 4 consisting of a projected surface 4a and bottom surface 4b is formed on the joining part 2b of the die-cast mold member 2. The projection part 4a formed in a columnar shape with 0.2 mm height is arranged so as to be distributed nearly uniformly on the joining surface 4 and the area of the bottom surface of the joining surface 4 is about 10% for the entire area of the joining surface 4. When the die-cast mold members 1, 2 are put one upon the other integrally by applying an epoxy resin system adhesive to the joining surface 3, the separation distance between the joining surfaces 3, 4 is regulated by the projection 5 and an adhesive layer 6 having 0.2 mm thickness is formed in about 90% of the area between the joining surfaces 3, 4 and the die-cast mold members 1, 2 are favorably joined together.
