Double-shot molded part separation method

Abstract

The invention discloses a double-shot molded part separation method. The double-shot molded part separation method comprises a shell, horizontal pressing plates and a vertical pressing plate. Placinggrooves are formed in the four walls of an inner cavity of the shell, and the horizontal pressing plates are installed in inner cavities of the placing grooves. First hydraulic cylinders are mounted on the four side walls of the shell, piston rods of the first hydraulic cylinders penetrate through the outer wall of the shell and are fixedly connected with the horizontal pressing plates, and the vertical pressing plate is arranged at the upper end of an opening of the shell. The top of the vertical pressing plate is fixedly connected with a piston rod of a second hydraulic cylinder, and the topof the second hydraulic cylinder is mounted at the bottom of a fixed structure. According to the double-shot molded part separation method, double-shot molded parts are extruded by extrusion, the compression resistance of PC is general, and the flexural property of TPU is high, so that the PC is broken under the action of the external force, then filtering is performed through a filtering hole toachieve the separation effect, the operating cost is low, the danger is avoided, and the double-shot molded part separation method is suitable for widespread popularization and use.

Description

technical field [0001] The invention relates to a separation method, in particular to a separation method of two-color injection molded parts. Background technique [0002] The existing two-color injection molded parts will be worn and damaged after being used for a long time. These injection molded parts will be recycled. In order to avoid waste of resources, after the existing injection molded parts are recycled, the two-color injection molded parts need to be separated. Different raw materials are recovered separately. The existing separation method is to separate by chloroform, but chloroform is more toxic, and the sale of chloroform is strictly controlled by the state, and the cost of using it for separation is relatively high. And it is prone to danger. Therefore, we propose a separation method for two-color injection molded parts. Contents of the invention [0003] The purpose of the present invention is to provide a method for separating two-color injection molde...
