Abstract

PURPOSE: To minimize the quantity used of accelerator and to adjust automatically the curing speed for molding at the ordinary temperature by a method wherein the temperature of the sand in a sand hopper is detected, the supplying quantity of the accelerator to a mixer is adjusted, resin liquid is supplied continuously and the accelerator can be supplied freely.
CONSTITUTION: The operating part 18 of a quantative supplier 12 for resin liquid operates respectively an upper limit and a lower limit air limit switch 35, 38, drives a four-part-two-position sluice valve 17 and the resin liquid 20 is supplied continuously to a mixing tank 6. A piston pump 40 is driven by an air-suction-exhaust device 59 through an air cylinder 42 and the accelerator 53 is supplied to the mixing tank at any time and at any interval. The temperature of the sand 4 is detected by a temperature sensor 50, the detected signal 51 is sent to a controller 48, the hydraulic pressure 49 corresponding to the detected signal is given to a servo cylinder 47 to control strokes S of a piston pump 40 and to supply the accelerator at quantities suitable for the temperature of the sand 4.
