PROBLEM TO BE SOLVED: To provide a molding device which can improve the efficiency of a molding operation for a product, and further, even if a residual molten metal is poured into a storage chamber, the molding operation can be properly performed. SOLUTION: An extrusion rod 40 is inserted into a cylindrical body 42 stored in a lower die 37, so as to be movable to the upper and lower directions, and a storage chamber 47 for a molten metal Y is provided by the upper face of the extrusion rod 40 and the inner circumferential face of the cylindrical body 42. A cavity is formed by the first molding face 371 of the lower die 37 and the second molding face 541 of the upper die 54. A function as a damper chamber storing the molten metal Y is imparted to the storage chamber 47. When the molten metal Y in the storage chamber 47 is extruded into the cavity by the extrusion rod 40, the residual molten metal Y is stored in the upper part of the storage chamber 47.
