Title: Die casting method by stroke controlling molten metal supply
Inventor: MARUYAMA RYUKICHI
IPC: B22D39/02
Filed: 1991-10-29
Abstract: PURPOSE:To make the accuracy for supplying the fixed quantity high and to reduce the entrapment of air by driving stroke of a plunger tip inserted in a plunger sleeve immersed in molten alloy with a hydraulic service cylinder driven with a servo motor. CONSTITUTION:A molten metal surface detector 18 arranged at the molten metal heat holding furnace 9 detects the molten Al 6 level. This value is received with an arithmetic device 19 to calculate the stroke of the plunger tip 13. A servo motor controller 20 outputs a pulse command corresponding to this stroke to the servo motor 16, and the servo motor 16 shifts the hydraulic servo cylinder 15 to a command position. The plunger tip 13 precisely supplies the molten Al 6 into the injection sleeve 4. By advancing the injection piston 5, the molten Al 6 is pushed into the cavity 3 to make a product. This operation can be executed in the extremely high accuracy for supplying the fixed quantity, and the entrapment of the air and spattering of the molten metal are little.
