Japanese Patent JP7280817
Kind Code:
B2
Abstract:
To provide a mold capable of improving cooling performance, and a molding device.SOLUTION: A mold 11 is divided by a first member 50 having a molding surface 47 for molding a metal pipe material 40, and a second member 51 supporting the first member 50 on a side opposite to the molding surface 47. The second member 51 is formed with a slit 53 which extends along a division surface 51a and is opened on the division surface 51a. The slit 53 constitutes a cooling part 61 that is at least a part of a flow channel 60 by joining the first member 50 and the second member 51. Thus, the cooling part 61 is formed of the slit 53 opened in the division surface 51a, which facilitates manufacture of the cooling part 61 and maintenance. Facilitation of manufacture of the cooling part 61 enables a design of a flow channel having good cooling efficiency, and deterioration in cooling efficiency due to insufficient maintenance can be suppressed. Therefore, cooling efficiency of the mold 11 can be improved.SELECTED DRAWING: Figure 5
