Abstract:
PROBLEM TO BE SOLVED: To provide a method of controlling mold temperature by which a mold is effectively cooled to improve the quality and productivity of a die cast product when the mold is forcedly cooled by using a coolant during die casting.SOLUTION: In the method of controlling mold temperature, a mold includes: fixed mold cooling piping and a fixed mold temperature sensor in a fixed mold; movable mold cooling piping and a movable mold temperature sensor in a movable mold; core mold cooling piping and a core mold temperature sensor in a core mold; and coolant piping and a mold temperature sensor at a predetermined position corresponding to the temperature distribution of the mold. As a result, the controlled flow rate of a cooling medium is distributed in the respective cooling pipings.

PROBLEM TO BE SOLVED: To provide a low-cost and efficient melting furnace for a medium-size business which can modify an upper part of the material supply tower of a currently possessed metal melting furnace and effectively use waste heat energy.SOLUTION: In the existing metal melting furnace having a material supply tower 3 with a flue 4 therein, a melting chamber 30, and a storage chamber 40, a vertical portion of the material supply tower 3 is cut into the upper part and the lower part. In the metal melting furnace 1, the upper part which includes a preheating chamber 5 having a material infusion aperture 8 with an openable/closable lid 9 in place of the separated upper part and a fume extraction cylinder 13 is formed in a way that the upper part is connected with the remaining lower part.
Abstract:
PROBLEM TO BE SOLVED: To provide a Stirling engine power generation and hot-water supply system using waste heat of a melting furnace, considering maintainability. SOLUTION: In a Stirling engine power generation device using, as a heat source, the waste heat not effectively used and exhausted of the heat quantity generated at respective processes in the melting furnace melting raw material, the Stirling engine power generation and hot-water supply system using the waste heat of the melting furnace is characterized in that from a waste heat recovery implement having a heater part of a Starling engine section detachably provided on a waste heat recovery implement mounting part of the melting furnace, heat in the melting furnace is transmitted to a Starling engine heat receiving part through working fluid in the heater part to drive a Starling engine, so that a part of the electricity obtained from a power generator operated together by the driving of the Starling engine is supplied as electric power for in-factory illumination, air conditioner, etc., and hot water heated through a heat exchanger provided additionally to the Stirling engine is stored in a hot water tank and used.
