When the clamping mechanism 6 rotates to the cam area of ​​the cam plate 1, the spring sliding seat 62 in the clamping mechanism 6 is ejected outward, and guide rollers 63 and a telescopic clamping claw assembly 64 are respectively provided at the upper and lower ends of the spring sliding seat 62, and the telescopic clamping claw assembly 64 includes two rotating arms 641 and a clamping claw 642. When the spring sliding seat 62 is ejected outward, the telescopic clamping claw assembly 64 is opened.

[0022] An end cover 4 is disposed at the upper end of the cam disc 1, a rotating shaft 5 is disposed at the lower end of the end cover 4, the upper end of the rotating shaft 5 is connected to the end cover 4 via a bearing, and the end cover 4 and the rotating material disc 2 are connected to the rotating shaft 5 via bearings respectively.

[0023] The output end of the cam divider 3 is connected to the rotating shaft 5, and the rotating shaft 5 is rotatably connected to the rotating material tray 2 through a bearing, and the rotating shaft 5 drives the rotating material tray 2 to intermittently rotate together.

[0024] The cam disc 1 is also provided with a material unloading positioning mark 7 and a material loading positioning mark 8. The rotary material tray 2 corresponding to the material unloading positioning mark 7 is connected to a material unloading channel for unloading special-shaped injection molded parts, and the rotary material tray 2 corresponding to the material loading positioning mark 8 is used for loading special-shaped injection molded parts.

[0025] The rotating material tray 2 is provided with a plurality of slots 9 , and a plurality of clamping mechanisms 6 are arranged to match the slots 9 . The plurality of clamping mechanisms 6 are arranged at equal distances with the rotating material tray 2 as the center.
