摘要： [TASK] To provide a mold forming apparatus capable of reliably causing a foamed mixture to appropriately fill a cavity of a forming mold by a simple configuration, and capable of achieving reduction in size. [MEANS OF SOLVING THE PROBLEM] The mold forming apparatus includes: a storage tank 1 that has in its bottom 1a a plurality of injection ports 10 capable of being opened and closed, and that stores a foamed mixture; a forming mold 2 that has a plurality of runners 20, corresponding to the injection ports 10, into which the foamed mixture is introduced through the injection ports 10 of the storage tank 1, and that has cavities 21 for forming the introduced foamed mixture into a mold in a predetermined shape; and pressing means 3 that is disposed so as to correspond to the forming mold 2 and that presses the foamed mixture stored in the storage tank 1 to inject the foamed mixture into the cavities 21 through the runners 20 of the forming mold 2, wherein a parting surface 22 of the forming mold 2 is formed parallel to a pressing direction P of the pressing means 3, and the runners 20 of the forming mold 2 are formed in the parting surface 22 and are tilted with respect to the pressing direction P of the pressing means 3 so as to spread apart from inlets 20a toward outlets 20b guided to the cavities.

摘要： When pressing kneaded sand in a kneading sand tank into a mold by a pressing member, a pressing force applied to a kneaded sand layer in the kneading sand tank is monitored and a moving position of the pressing member is monitored from when the pressing member starts to move. A pressing start time at which the kneaded sand starts to flow into the mold is identified based on the pressing force applied to the kneaded sand layer in the kneading sand tank, and a pressing starting position of the pressing member at the pressing start time is identified. As a result, the pressing start time and the pressing starting position of the pressing member when the kneaded sand starts to flow into the mold are accurately identified, so the reliability of a filling evaluation of the kneaded sand into the mold is improved.

摘要： When a molded article is obtained by which foamed sand is packed into a metallic mold, heated and solidified, vapor and gas that have been generated through the heating and solidification of the foamed sand are smoothly discharged from the cavity.
A cavity C is formed by clamping a metallic mold 2, and foamed sand S is packed into the cavity C. When heating and solidifying the foamed sand S, a mold clamping force is reduced to form a slight gap L in the metallic mold 2 while maintaining the cavity C. Gas and water vapor that are generated when heating and solidifying the foamed sand S can be smoothly discharged from within the cavity C to the outside through the gap L, and thus the baking time of the foamed sand S can be shortened. Even if solidified binder accumulates on slits 16, gas and water vapor can be reliably discharged from within the cavity C to the outside via the gap.摘要翻译： 当获得将发泡砂填充到金属模具中的模制品时，加热并固化，通过发泡砂的加热和固化而产生的蒸气和气体顺利地从模腔中排出。 通过夹持金属模具2形成空腔C，并将泡沫沙S填充到空腔C中。当加热并固化泡沫沙S时，模具夹紧力减小，从而在金属模具2中形成微小间隙L 保持空腔C.在加热并固化发泡砂S时产生的气体和水蒸气可以通过间隙L顺利地从空腔C内排出到外部，因此可以缩短泡沫砂S的烘烤时间 。 即使固化的粘合剂积聚在狭缝16上，气体和水蒸气也能够经由间隙可靠地从空腔C内排出到外部。
