あった。In the conventional method, if the force of pushing the crosshead (crosshead pushing force) by the clamping cylinder or the like is constant as shown in FIG. Moves forward, and as the distance to the mold touch position (movable plate stroke) becomes smaller, the force for pressing the movable plate (movable plate pressing force) increases. That is, the ratio (magnification) of the force transmitted to the movable platen via the toggle device with respect to the force of the mold clamping cylinder (crosshead pressing force) increases. Therefore, the following problem occurs in the process of compressing the molded product. That is, if the compression force is set based on the state in which the mold is opened at the initial stage of compression, the compression force at the mold touch position becomes excessive. Further, if the compression force is set based on the state at the mold touch position, the compression force when the mold is opened in the initial stage of compression becomes insufficient.
For this reason, a uniform compression force cannot be applied to the molded product during the compression process, and it has been difficult in some cases to set molding conditions.

That is, the pressing force of the crosshead is made variable so that the pressing force of the movable plate becomes constant depending on the position of the crosshead. Thereby, the pressing force of the movable platen, that is, the compressive force on the molded product during the compression step can be kept constant regardless of the position of the crosshead, so that molding conditions can be easily set.
