素材を金型に射出する射出部の各機構を駆動する駆動源
として油圧駆動源を用いるのが主流であった。[Conventional Technique 11] Conventionally, in injection molding machines that convert materials such as plastics into required molded products, each mechanism of the mold clamping section of the mold and the injection section that injects mold-molten material into the mold is driven. The mainstream was to use a hydraulic drive source as the drive source.

向にある。Recently, in order to eliminate non-uniformity of molded products by controlling the pressure inside molds for injection molding plastics with high precision, and to eliminate the oil smoke atmosphere and create molded products without oil adhesion. Furthermore, there is a tendency for electric servomechanisms to be used as drive sources for purposes such as saving maintenance of the drive unit.

る。Mold closing → mold clamping → injection → holding pressure → cooling (plasticization) → mold loosening → mold opening → ejection This control is carried out. In the above operation process, the AC type used as a drive source in electric servo mechanisms!

This regeneration operation is performed, for example, at the time of mold clamping, just before the end of injection, just before the end of mold opening, and at the time of ejection. In addition, the time required for one cycle of the eight operation modes is about 15 to 30 seconds, and the AC motor used in the electric servo mechanism is required to operate with high frequency of start and stop operations, and the regenerative operation of the motor is required. is also performed frequently.
