2. A method for controlling an electric resin molding machine including an electrically driven double toggle type mold clamping mechanism and a strain sensor arranged on a mold clamping shaft.
The movable platen that holds the other side of the molding mold is moved to the fixed plate side by the mold clamping mechanism with respect to the fixed plate that holds one side of the molding die, and the mold touch position is determined from the moving distance of the movable platen. Is detected, and the moving distance of the movable plate from this mold touch position to the lockup position where the specified mold clamping force is obtained is calculated based on the mold touch position to control the mold clamping. A control method for an electric resin molding machine.
3. The control method for an electric resin molding machine according to claim 2, wherein a mold clamping force at the time of lockup is detected by a strain sensor, and the lockup position is corrected by the detected mold clamping force.
4. The control method for an electric resin molding machine according to claim 2, wherein the deviation of the offset value of the strain sensor is detected and the lockup position is corrected.
5. Any one of claims 2 to 4, wherein the abnormality of the strain sensor is detected from the detection value of the lockup position detected from the mold clamping force detected by the strain sensor and the moving distance of the movable platen. The control method of the electric resin molding machine described in 1.
6. Any one of claims 2 to 4 in which an abnormality of the mold clamping shaft is detected from a detection value of a lockup position detected from a mold clamping force detected by a strain sensor and a moving distance of a movable platen. The control method of the electric resin molding machine according to the item.
7. Any one of claims 2 to 4, wherein an abnormality of the mold is detected from a detection value of a lockup position detected from a mold clamping force detected by a strain sensor and a moving distance of a movable platen. The control method of the electric resin molding machine described in 1.
8. The control method for an electric resin molding machine according to claim 3, wherein the strain sensor detects strain in the direction of being stretched by a mold clamping force.

By feeding back the mold clamping force detected by the strain sensor 6 and adjusting the mold clamping force during continuous operation so as to be a predetermined mold clamping force each time, the double toggle mechanism 8 becomes familiar and the temperature changes. The variation in the lockup position due to the change of the constituent elements such as the elongation of the tie bar 5 due to the above is eliminated, a constant mold clamping force can be obtained from the start of molding, and a good product can be obtained by stable resin molding.
