Abstract:
1. An operating method for a foamed resin molding machine, comprising: providing a foamed resin molding machine including: predetermining the die thickness by moving the die tightening housing by the die thickness adjusting means corresponding to the thickness of the tightened die, measuring the die tightening force at a-the die tightening limit, finely adjusting the die thickness by the die thickness adjusting means on the basis of the measured result, and once opening the die and then tightening the die again, by controlling the expansion of the toggle link by the ball screw rotation control means, thereby controlling the cracking gap position at the-a time of filling said cavity with materials and at a time of releasing the solidified material from said cavity, and wherein the die tightening limit is between 30 to 70% of the die tightening force realized during actual molding.
