Title:
LOW PRESSURE CASTING DEVICE, AND HEATER UNIT FOR LOW PRESSURE CASTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/002441
Kind Code:
A1
Abstract:
[Problem] To ensure durability by suppressing a rise in the temperature of a sealing terminal portion or wiring, even if an infrared lamp heater is used as a sub-stalk heating means. [Solution] In this low pressure casting device, a sub-stalk heating means consists of an infrared lamp heater 22 comprising a rod-shaped transverse straight portion 32 which is disposed in a heating space 17 formed around the sub-stalk and which includes carbon fiber filaments 37, and a sealing terminal portion 35 which is provided at the end of the transverse straight portion 32, and through which lead wires 38 that are electrically connected to the carbon fiber filaments 37 are led out, wherein: the heating space 17 is divided into an upper space 17A and a lower space 17B by means of a metal dividing plate 21 that includes a thermally insulating board 25; the infrared lamp heater 22 bends between the transverse straight portion 32 and the sealing terminal portion 35; and the transverse straight portion 32 and the sealing terminal portion 35 are respectively disposed in the upper space 17A and the lower space 17B.
