摘要： PROBLEM TO BE SOLVED: To provide a casting structure capable of advantageously casting a molding die containing a convex part for improving cooling efficiency in a flow channel of a cooling medium.SOLUTION: A composite type structure includes a lost model and a sand mold which are combined for casting a molding die. The sand mold includes a convex form for forming a flow channel of a cooling medium in the molding die by removing the sand mold after casting, and the convex form of the sand mold includes a concave part for increasing a surface area of the flow channel. By engaging the sand mold and the lost model with each other, the concave part is sealed, and in this way, the composite type structure is constituted.
摘要翻译：要解决的问题：提供一种能够有利地铸造包含凸起部分的模具的铸造结构，以提高冷却介质的流动通道中的冷却效率。解决方案：复合型结构包括丢失模型和砂模，结合铸造模具。砂模包括用于通过在铸造之后移除砂模形成模具中的冷却介质的流动通道的凸形，并且砂模的凸形包括用于增加流动通道的表面积的凹部。通过将砂模与迷失型相互配合，将凹部密封，构成复合型结构体。

摘要： PROBLEM TO BE SOLVED: To provide a low temperature mold and a low pressure casting method, which uses a mold of a low temperature to allow low pressure casting, resulting in a fine system of a casting, while capable of manufacturing a hollow thin-wall casting of meter size.SOLUTION: The average inner surface temperature of a cavity part of a mold is 250°C or lower, while the inner surface temperature at a pouring opening of the mold is 350°C or higher. A powder mold-releasing agent is applied on the inner surface of the cavity part of the mold by 1-10g per 1m. The hollow part of a hollow core installed in the cavity is exhausted to the outside of the mold through an opening part of a base board while the inside space of a melting furnace is pressurized so that the cavity is filled with the molten metal in the melting furnace.
摘要翻译：要解决的问题：为了提供一种低温模具和低压铸造方法，其使用低温模具以允许低压铸造，导致铸件的精细系统，同时能够制造中空薄壁铸造米尺寸。解决方案：模具的空腔部分的平均内表面温度为250℃或更低，而模具的倾倒开口处的内表面温度为350℃或更高。在模具的空腔部分的内表面上，每1m 2 施加粉末脱模剂1-10g。安装在空腔中的中空芯的中空部分通过基板的开口部分排出到模具的外部，同时熔化炉的内部空间被加压，使得空腔中的熔融金属被熔化炉。版权所有（C）2012，JPO＆INPIT
