DETAILED DESCRIPTION

[0017] To make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the embodiments of the utility model will be described clearly and completely below in combination with the drawings of the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0018] Referring to Figure 1 The structure schematic view of the present application is shown, the injection molding automatic sprue shearing device comprises a U-shaped support frame 1 mounted at one end of a conveying frame and a group of pneumatic scissors arranged on the U-shaped support frame; the supporting legs 2 on the two sides of the U-shaped support frame are mounted on the end face of the conveying frame; and an electrostatic removal device is further arranged on the end face of the conveying frame below the U-shaped support frame. The excess rubber strips of the two car lights are simultaneously sheared off by the pneumatic scissors group, and the car lights are simultaneously subjected to electrostatic removal treatment, thereby greatly improving the production efficiency.

[0019] The pneumatic scissors group comprises two oppositely arranged pneumatic scissors 3, the pneumatic scissors are both mounted on the crossbeam 4 of the U-shaped frame through a support assembly, and the scissors end 5 of the pneumatic scissors faces upward. The excess rubber of the two car lights is sheared off by the pneumatic scissors, which facilitates the subsequent annealing process operation.
