摘要： [Problems] To provide equipment for molding a mold with a molding flask, which can easily be used with a mold molding auxiliary tool such as a sleeve on a model plate and, at the same time, can realize high productivity, is less likely to cause the wear of the model plate, and can mold a mold with a molding flask having uniform strength. [Means to solve problems] The equipment for molding a mold with a molding flask, is characterized in that it comprises: a means for introducing molding sand that introduces molding sand into a molding flask and a filling frame, using compressed air, the molding flask and the filling frame being mounted on a model plate in a superimposed state; the means for introducing molding sand comprising a shielding means having a plurality of feet that can enter the filling frame and can be temporarily held at the position that is spaced apart at the predetermined distance from the model part of the model plate, which model part faces the plurality of feet. The equipment further comprises a squeezing means provided adjacent to the means for introducing molding sand, which squeezing means squeezes the molding sand in the molding flask, and the filling frame, and a transfer means for carrying the model plate, the molding flask and the filling frame into and out of both the means for introducing molding sand and the squeezing means.

摘要： When employing an under-blow scheme for blowing core sand into a core box located on the upper side, a core sand filling method which can favorably fill the core box with core sand, thereby contributing to improving the efficiency in manufacturing cores, is provided.
The core sand filling method comprises a step of operating an aeration air supply means 9A, so as to float and fluidize core sand within a sand blow chamber 4 and, when a pressure Pf of the sand blow chamber 4 measured by the first pressure sensor 14 reaches a first pressure P1, operating a compressed air supply means 7A and a step of stopping the aeration air supply means 9A and compressed air supply means 7A from operating when each of the pressure Pf within the sand blow chamber 4 and a pressure Pc within a sand storage chamber 5 is a second pressure P2 or higher while a differential pressure ΔP = Pc - Pf is a third pressure P3 or lower.摘要翻译： 在将芯砂吹入位于上侧的芯盒内的情况下，提供一种芯砂填充方法，其可以有利地将芯砂填充到芯盒中，从而有助于提高芯的制造效率。 芯砂填充方法包括如下步骤：操作曝气供气装置9A，以便使砂芯4内的芯砂浮起并流化，并且当由第一压力传感器14测量的砂流室4的压力Pf 达到第一压力P1，操作压缩空气供应装置7A，以及当吹砂腔室4内的每个压力Pf和压力Pf内的压力Pc停止曝气空气供应装置9A和压缩空气供应装置7A的操作时， 砂储存室5是第二压力P2或更高，而压差ΔP= Pc-Pf是第三压力P3或更低。

摘要： A cast mold fabricating device supplies thickener-coated sand and steam into a mold forming die at an optimum timing to shorten a mold fabrication time. The device includes the die 2 with an injection inlet 1, a sand supply head 4 for supplying and filling the thickener-coated sand 3 into the die, a steam supply head 5 for supplying steam into the die 2 to solidify and/or cure a thickener of the sand by application of heat of the steam. The device further a vertical drive 6 for lowering the sand supply head 4 to a position where the injection inlet 1 is connected to a sand nozzle 8 of the sand supply head 4 , and a horizontal drive 7 for advancing the steam supply head 5 to a position where the injection port 1 is connected to a steam nozzle 9 of the steam supply head 5 .
