MULTI-CYLINDER TYPE GRAVITY CASTING MACHINE CAPABLE OF MINIMIZING A LOAD ON EACH HYDRAULIC CYLINDER BY RESPECTIVELY EQUIPPING THE HYDRAULIC CYLINDERS FOR ELEVATING A PLURALITY OF EQUIPPED MOLDS

摘要

PURPOSE: A multi-cylinder type gravity casting machine is provided to simultaneously produce various kinds of products by controlling each hydraulic cylinder to be respectively actuated and by minimizing a load on each hydraulic cylinder by respectively equipping the hydraulic cylinders for elevating plurality of equipped molds.;CONSTITUTION: A multi-cylinder type gravity casting machine comprises a stand(10), mold assemblies(20,30), molten metal storages(40,50). The stand(10) is fixed on a work plane. The mold assemblies comprises fixed molds(22,32), movable molds(24,34), and hydraulic cylinders(26,36), and are rotatably coupled to the stand(10). The plural fixed molds are arranged in a row. The movable molds are installed to be capable of being elevated on the upper portion of the fixed molds. The hydraulic cylinders are respectively installed at the movable molds for elevating the movable molds. The molten metal storages temporarily accommodate molten metals and are formed to supply the molten metals through inlet ports by a quick action of the mold assemblies. The hydraulic cylinders are controlled to be respectively actuated. The molten metal storages are respectively equipped in unit mold assemblies for respectively supplying molten metals to the unit mold assemblies which comprises the fixed molds and the movable molds corresponding to the fixed molds.;COPYRIGHT KIPO 2013
