Abstract
In pouring molten metal in a die casting device wherein a shot sleeve for supplying molten metal in a die cast mold is substantially horizontally arranged, a guide means for conducting molten flow is obliquely removably inserted into said shot sleeve through an opening provided at a top portion of said shot sleeve so as to guide a flow of molten metal directly into a molten holding space provided at a forward end portion of said shot sleeve.
Claims14
A method for pouring molten metal in a die casting device wherein a shot sleeve for supplying molten metal to a die cast mold is substantially horizontally disposed in the die casting device, comprising the steps of obliquely inserting an inclined guide means into said shot sleeve through an opening provided in a top portion of said shot sleeve to the extent that the lower outlet end of said guide means contacts a bottom portion of said shot sleeve, and pouring molten metal along said guide means toward the inside of said shot sleeve as a quiet flow.
An apparatus for pouring molten metal in a die casting device wherein a shot sleeve for supplying molten metal into a die cast mold is substantially horizontally arranged, comprising an inclined guide means removably and obliquely disposed in said shot sleeve through an opening provided in a top portion of said shot sleeve to the extent that the lower outlet portion of said guide means contacts the bottom portion of said shot sleeve, said guide means being adapted to guide molten metal into said shot sleeve as a quiet flow.
In a die casting apparatus comprising a stationary platen and a movable platen, means for moving said movable platen toward said stationary platen to define a molding cavity therebetween, a molten metal holding space disposed adjacent said molding cavity and communicating with said molding cavity and a substantially horizontally disposed shot sleeve communicating with said molten metal holding space, said shot sleeve being adapted to accommodate a piston means, the improvement which comprises an opening in the upper portion of said shot sleeve and a removable inclined guide means in said opening, said guide means being obliquely disposed i n said opening and extending to contact the bottom portion of said shot sleeve whereby molten metal may be poured thereinto as a quiet flow.
