摘要： The present disclosure provides a clamping assembly in operative connection with a mold of an injection-molding apparatus. The clamping assembly includes a fixed plate, a rear plate, a plurality of tie bars, a movable plate, a driving module, and a temperature adjuster. The rear plate is spaced apart from the fixed plate. The tie bars are interlinked with the fixed plate and the rear plate and provided with a plurality of channels. The movable plate, between the fixed plate and the rear plate, is capable of moving with respect to the fixed plate along the tie bars. The driving module interlinks the rear plate and the movable plate. The temperature adjuster is employed to supply a fluid into the channels to remove heat from the tie bars, thereby preventing non-uniform thermal expansion of the tie bars, and hence preventing the structural wear and flash issues.
