a sprue bush provided in the first base mold and formed with at least a part of a sprue flow path to which a molding material is supplied; a first mold plate formed with a runner flow path through which the molding material supplied from the sprue flow path flows, a gate through which the molding material supplied from the runner flow path flows, and a part of a cavity space which is filled with the molding material supplied from the gate and in which a molded product is molded; a base intermediate mold loaded with the first mold plate; a second mold plate formed with a part of the cavity space; a second base mold loaded with the second mold plate and relatively moving in a mold opening/closing direction with respect to the first base mold; a base intermediate mold driving device positioning and fixing the base intermediate mold at any position between the first base mold and the second base mold; and a controller controlling the base intermediate mold driving device to position and fix the base intermediate mold so that the first mold plate and the first base mold are in contact with each other when the molded product is taken out. ### Claim 2 (depends on 1) The mold apparatus according to claim 1, wherein a cassette mold comprising the first mold plate and the second mold plate is a two-plate mold, and the controller controls the base intermediate mold driving device to position and fix the base intermediate mold so that the first mold plate and the first base mold are in contact with each other. ### Claim 3 (depends on 1) The mold apparatus according to claim 1, further comprising a runner stripper plate provided between the first base mold and the first mold plate, wherein a cassette mold comprising the first mold plate, the second mold plate, and the runner stripper plate is a three-plate mold, and the controller controls the base intermediate mold driving device to position and fix the base intermediate mold so that the first mold plate and the second mold plate are in contact with each other when a sprue runner formed in the sprue flow path and the runner flow path is taken out. ### Claim 4 (depends on 3) The mold apparatus according to claim 3, wherein the runner stripper plate has a through hole that communicates with the runner flow path, and the mold apparatus further comprises: a runner locking part formed with an inverse tapered space which communicates with the through hole on the side of the first base mold and has an inverse tapered shape, wherein a locking portion made of the molding material is formed in the inverse tapered space; and a runner unlocking means moving the runner stripper plate away from the runner locking part to unlock the locking portion. ### Claim 5 (depends on 4) The mold apparatus according to claim 4, further comprising a runner locking plate provided between the first base mold and the runner stripper plate, wherein the runner locking part is provided in the runner locking plate. ### Claim 6 (depends on 5) The mold apparatus according to claim 5, further comprising a runner locking plate moving means moving the runner locking plate in a mold opening direction to form a predetermined gap between the first base mold and the runner locking plate. ### Claim 7 (depends on 4) The mold apparatus according to claim 4, wherein the runner locking part is provided in the first base mold. ### Claim 8 (depends on 4) The mold apparatus according to claim 4, wherein the runner unlocking means comprises a runner stripper plate driving device that moves the runner stripper plate in a mold opening direction. ### Claim 9 (depends on 4) The mold apparatus according to claim 4, wherein the runner unlocking means comprises: a tension link connecting the first mold plate and the second mold plate to limit a degree of opening between the first mold plate and the second mold plate; a puller bolt having a head portion for locking the first mold plate; and a stop bolt having a head portion for locking the first base mold, wherein the runner stripper plate is interposed between and connected with an end portion of the puller bolt and an end portion of the stop bolt.
