A technique is provided capable of favorably preventing generation of a shrinkage cavity in solidification of molten metal poured into a casting mold, and increasing accuracy of an assembling position of a core to a mold, in casting a caliper. A caliper casting device for casting a caliper for a disc brake including a cylinder into which a piston is fitted, and a rotor housing surface that defines a space for housing a disc rotor, includes: a mold; and a core placed in the mold, the mold having a rotor housing surface forming portion that forms a part of the rotor housing surface after casting, and the core being positioned and held in the rotor housing surface forming portion during casting, and forming a part of the rotor housing surface together with the rotor housing surface forming portion after casting.
A caliper casting device for casting a caliper for a disc brake including a cylinder into which a piston is fitted, and a rotor housing surface that defines a space for housing a disc rotor, comprising;
A core used in a caliper casting device for casting a caliper for a disc brake including a cylinder into which a piston is fitted, and a rotor housing surface that defines a space for housing a disc rotor, wherein the core is positioned and held, during casting, in a rotor housing surface forming portion of a mold in the caliper casting device, which rotor housing surface forming portion is configured to form a part of an inner wall surface of the rotor housing surface after casting, and wherein the core forms a part of the inner wall surface of the rotor housing together with the rotor housing surface forming portion after casting, and wherein:
A mold used in a caliper casting device for casting a caliper for a disc brake including a cylinder into which a piston is fitted, and a rotor housing surface that defines a space for housing a disc rotor, wherein the mold has a rotor housing surface forming portion that is configured to form a part of an inner wall surface of the rotor housing after casting, and can position and hold a core that forms a part of the inner wall surface of the rotor housing together with the rotor housing surface forming portion after casting, and wherein:
A manufacturing method for manufacturing a caliper for a disc brake including a cylinder into which a piston is fitted, and a rotor housing surface that defines a space for housing a disc rotor, wherein:
