[0017] The present application provides a double-capstan material taking device for injection molding, which combines Figs. 1-3As shown, it comprises a fixed seat 1, a set of taking mechanisms is arranged at both ends of the fixed seat 1 respectively, each set of taking mechanisms comprises a suction cup assembly 2 and a clamping assembly 3, at least two vertical sliding grooves 11 and a plurality of first through holes 12 are arranged at both ends of the fixed seat 1, the vertical sliding grooves 11 are symmetrically arranged along the center line respectively, the plurality of first through holes 12 are arranged along the center line, a plurality of second through holes 13 are arranged at positions close to the edges of both ends of the fixed seat 1 at equal intervals. The suction cup assembly 2 is installed in the vertical sliding groove 11 and the first through hole 12, and the clamping assembly 3 is installed in the second through hole 13. The installation positions and quantities of the suction cup assembly 2 and the clamping assembly 3 can be selected according to actual needs to match different products 5. When the taking device for double-chuck injection molding is running, the product 5 is taken out by the suction cup assembly 2, and the sprue 4 is clamped by the clamping assembly 3. The taking device drives the product 5 and the sprue 4 to leave the injection molding device synchronously. When the taking device moves to the sprue recovery position, the clamping assembly 3 is opened to make the sprue 4 fall into the sprue crushing device for crushing.

[0018] Specifically, the suction cup assembly 2 comprises a suction cup body 21, a mounting screw 22 and a gas pipe joint 23. One end of the mounting screw 22 is fixedly connected with the suction cup body 21, and a first nut is further arranged on the mounting screw 22.
