For horizontal injection die-casting equipment and die-casting method

摘要

PROBLEM TO BE SOLVED: To provide a horizontal injection die casting apparatus which prevents the entry of molten metal into a clearance between the outer peripheral surface of a plunger chip and the inner peripheral surface of a sleeve hole.;SOLUTION: A horizontal injection die casting apparatus 1 includes a fixed mold 3 and a movable mold 4 for defining a cavity 7 together with the fixed mold 3. Furthermore, it includes a mold sleeve 9 engaged with the fixed mold 3, a sleeve 11 on the side of a casting machine that is connected with the mold sleeve 9, and a plunger chip 12 that advances in a horizontal direction within the sleeve 11 on the side of the casting machine and the mold sleeve 9 and injects the molten metal to the cavity 7. The mold sleeve 9 has a sleeve hole 9B, wherein the diameter D2 of the rear end 9B1 of the sleeve hole 9B is formed larger than the inside diameter D1 of the sleeve 11 on the side of the casting machine, and the diameter D3 of the sleeve hole 9B at the maximum advancing position of the plunger chip 12 is formed smaller than the diameter D2 of the rear end 9B1 of the sleeve hole 9B.;COPYRIGHT: (C)2012,JPO&INPIT
