Injection Molding Device

Abstract: a driving force transmission unit includes a rotary plate provided with a rotation axis at an eccentric position, and a support portion having a hole portion through which the rotation axis passes and being configured to support a plunger. the hole portion extends in a moving direction of the plunger. the support portion swings in an extending direction of the hole portion by rotation of the rotary plate. when dispensing processing is terminated, an angle is larger than 90 degrees and smaller than 180 degrees, the angle being formed between a linear line connecting the rotation axis and a center of the rotary plate to each other and the moving direction of the plunger as viewed in a direction of the rotation axis. a control unit controls a rotation speed of a motor according to the angle during the dispensing processing.
