Automatic shearing device for plastic product runner

Abstract

The invention discloses an automatic shearing device for a plastic product runner and belongs to the technical field of automatic shearing of the plastic product runner. The automatic shearing devicecomprises a shearing platform; a collecting cabinet is arranged at the bottom of the shearing platform; the upper side of the front end face of a rear plate is provided with a sliding chute; the sliding chute is provided with a corresponding slider; a fixing rod is arranged at the front end of the slider; the fixing rod is connected with a telescopic rod in an insertion manner; the front end of the telescopic rod is provided with a height adjusting cylinder; a piston rod is arranged at the bottom of the height adjusting cylinder; a shearing supporting plate is arranged at the bottom of the piston rod; a shearing pneumatic cylinder is arranged at the left side of the top of the shearing supporting plate; a shearing piston rod is arranged at the right end of the shearing pneumatic cylinder;a fixed blade matched with a movable blade is arranged inside the shearing supporting plate; and the front side of the top end of the shearing platform is provided with plastic product clamping pincers. By adopting the automatic shearing device to remove the runner on the plastic product, the cut is flat and smooth and do not affect the surface quality of the plastic product, and high work efficiency is realized.

Description

technical field [0001] The invention relates to the technical field of automatic nozzle shearing of plastic products, in particular to an automatic nozzle shearing device for plastic products. Background technique [0002] When plastic products are molded, there are liquid channels in the injection molding machine for the liquid to flow into the mold for molding. After the liquid has solidified, the solids in the liquid passages form spouts that adhere to the plastic product and need to be removed to obtain the desired size and appearance of the product. [0003] The current method of removing the nozzle is generally to cut it off with nozzle pliers, or to shovel it off with a knife. These two methods are time-consuming and labor-intensive, and the work efficiency is low, especially when the hardness of the plastic product is relatively high. At this time, the manual method is used. Just be difficult to remove the nozzle on the plastic product, and adopt manual method to re...
