PROBLEM TO BE SOLVED: To provide a mold tightening device in an injection molding machine capable of adjusting the bearing balance of a mold and in-mold parallel accuracy at high precision.SOLUTION: The space between a platen and a mold is provided with an adapter plate, the adapter plate is divided into a plurality of regions, the temperature per divided region is measured, and the temperature is adjusted per region. The temperature adjustment can be performed at a point closer to the center of the mold compared with a tie bar. Further, by performing the temperature adjustment of the adapter plate provided between the platen and the mold, the adjustment of a tie bar balance and in-mold parallel accuracy can be performed at high precision even during molding. |
