摘要： A casting method and casting mold able produce a casting having an island and connecting portion is disclosed. A casting having a body, an opening provided so as to pass through the body, an island arranged separated from the body in the opening, and a connecting portion joining the island and body is cast using a casting mold. The casting mold is provided with a body gate connected to a body cavity for forming the body and an opening gate connected to an island/connecting portion cavity for forming the island and the connecting portion. The body gate and opening gate are connected to a runner through body pin gates and opening pin gates; in addition, a die casting mold able to suitably change between a three-part mold structure and a two-part mold structure to cast a die casting is disclosed. The three-part mold structure die casting mold, a movable mold, a first cavity, a connection sleeve, a first runner, a pin gate, and an extension sleeve. When forming the two-part mold structure die casting mold, the fixed mold is removed, the extension sleeve insert inserted in the extension sleeve is removed, and the pin gate is filled by a pin gate insert. Further, the intermediate mold insert and the movable mold insert are replaced to form the two-part mold structure die casting mold forming the second cavity and second runner moving the movable mold with respect to the intermediate mold.

摘要： A casting method and casting mold able to easily produce a casting having an island and connecting portion at a high quality. A casting (1) having a body (11), an opening (12) provided so as to pass through the body, an island (121) arranged separated from the body in the opening, and a connecting portion (22) joining the island and body is cast using a casting mold (2). The casting mold is provided with a body gate (311) connected to a body cavity for forming the body and an opening gate (321) connected to an island/connecting portion cavity (32) for forming the island and the connecting portion. The body gate and opening gate are connected to a runner (33) through body pin gates (312) and opening pin gates (322), and also, a die casting mold able to suitably change between a three-part mold structure and a two-part mold structure and optimally cast a die casting, wherein the three-part mold structure die casting mold (2001) has a fixed mold (2002), an intermediate mold (2003), movable mold (2004), first cavity (2051), connection sleeve (2052), first runner (2053), pin gate (2054), extension sleeve (2057) in which the extension sleeve insert (2033) is inserted, etc. When forming the two-part mold structure die casting mold (2001), the fixed mold (2002) is removed, the extension sleeve insert (2033) inserted in the extension sleeve (2057) is removed, and the pin gate (2054) is filled by a pin gate insert (2036). Further, the intermediate mold first insert (2031) and movable mold first insert (2041) are replaced to form the two-part mold structure die casting mold (2001) forming the second cavity (2056) and second runner (2058) moving the movable mold (2004) with respect to the intermediate mold (2003).
