Claims

[Scope of utility model registration request]

A casting mold device having a cast-out pin protruding from the mold body into the cavity to form a concave shape in the casting, the cast-out pin having a protrusion projecting into the cavity and an outer periphery. The mold body has a male threaded part and an embedded part whose diameter is set to be approximately the same throughout the axial direction, and the mold body further has a depth of the embedded part of the cast piping. A cylindrical pin mounting hole with a bottom is formed to be equal to the length in the axial direction of the pin mounting hole, and the embedded portion is formed on the inner periphery of the pin mounting hole by screwing the cast-out pin. 1. A casting mold device having a cast-out pin, characterized in that a female threaded part is formed to screw with the male threaded part of the cast-out pin to bring an end surface of the embedded part of the cast-out pin into contact with a bottom surface of a pin mounting hole.
