Title:
RESIN MOLDING MOLD, HOT-WATER STORAGE TANK UNIT MANUFACTURING METHOD, AND HOT-WATER STORAGE TANK UNIT
Document Type and Number:
WIPO Patent Application WO/2021/210190
Kind Code:
A1
Abstract:
Provided are: a resin molding mold with which it is possible to spread a resin material over the entire cavity of the resin molding mold to achieve an enhanced insulation-member moldability; and a hot-water storage tank unit. A resin molding mold (500) consists of a lower mold (510) having a depression (512), the periphery of which is surrounded by first outer edge sections (511), and an upper mold (520) having a protrusion (522) that can be accommodated in the depression (512) and the periphery of which is surrounded by second outer edge sections (521); and serves to perform foam molding of an insulation member of a hot-water storage tank. The resin molding mold (500) is characterized in that: in the case in which the upper mold (520) is closed with respect to the lower mold (510), a cavity is formed as a result of the protrusion (522) being accommodated in the depression (512); and, furthermore, a plurality of air vents, which are sites at which the first outer edge sections (511) and the second outer edge sections (521) face each other via spaces formed by depressed surfaces (513, 523), establish communication between the top-most section of the cavity and the exterior of the resin molding mold (500).
