Description

Thermal spraying mold and manufacturing method

Since this is an open matter, no full text was included.

FIG. 2 is a cross-sectional view of the circular body of FIG. 1 in which Ni-P plating is performed. FIG.

3 is a cross-sectional view of the state in which Zn plating is applied to FIG.

4 is a cross-sectional view of a state in which Zn is thermally sprayed on FIG. 3.

Claims (3)

In the mold for casting production, the core part 4 is composed of a core part 4 and a holder part 6, and the core part 4 is plated with a Ni-P layer 1, a thermally sprayed Zn layer 2, and the Ni. A spraying mold, characterized in that the Zn plating layer (8) mediating the P layer (2), wherein the holder portion (6) consists of an iron cement (4) and an aluminum plate (5). In the method for producing a die for casting production, a first step (A) of plating the Ni-P layer (1) on (1) formed of carbon body and a Zn layer (on the Ni-P layer (1)). The second step (B) of thermal spray forming 2), and a holder part with an iron cement (4) and an aluminum plate (5) in the core part (3) consisting of the Ni-P layer (1) and the Zn layer (2). (6) A method for producing a thermal spray mold, characterized by comprising a third step (C). The method according to claim 2, wherein in the second step (B), before the thermal spray molding of the Zn layer (2), the Zn plating layer (8) is formed by plating zinc of the same material, and then the Zn layer (2) is sprayed. Method of producing a thermal spray mold, characterized in that to be molded. ※ Note: The disclosure is based on the initial application.
