DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, reference will be made to Figures 1-3, the specific implementation of the screw forming die for air conditioner compressors that facilitates demolding in the present utility model will be introduced, including a base 10 and a frame 11. A lower template 21 is provided on the base 10, and an upper template 22 is connected to the frame 10. The lower templates 21 are two that are centrosymmetric; and a cavity 23 is provided in the middle of the lower templates 21. A demolding mechanism is connected between the lower template 21 and the frame 10. The demolding mechanism includes a fixed block 31 fixedly connected to the outer side of the lower template 21. A connecting rod 33 is inserted into the fixed block 31. A cylinder 1 32 is connected to the frame 10. One end of the connecting rod 33 is fixedly connected to the output end of the cylinder 1 32. And a screw 34 is connected between the fixed block 31 and the connecting rod 33. The fixed block 31 and the connecting rod 33 are detachably connected by the screw 34. The two lower templates 21 are driven by the cylinder 1 32 to move synchronously and in opposite directions respectively. Limit plates 12 are connected to both sides of the upper end of the base 10. The two lower templates 21 move between the two limit plates 12. After the screw in the cavity 23 is formed, by starting the cylinders 1 32 on both sides, the lower template 21 of the screw moves outward, facilitating the removal of the formed screw.

[0020] And in order to prevent the adhesion between the formed screw and the lower template 21, a push rod 41 is also connected between the frame 10 and the lower template 21. One end of the push rod 41 passes through the inner side of the lower template 21 and is connected with a limit block 43. And the inner side wall of the limit block 43 is flush with the side wall of the cavity 23. A spring 42 is sleeved on the push rod 41. One end of the spring 42 abuts against the frame 10. The other end of the spring 42 abuts against the outer side wall of the lower template 21. By setting the push rod 41 and the limit block 43, when the lower template 21 moves outward, it can prevent the screw from adhering to the inner wall of the cavity 23 and push it out, facilitating demolding.

[0021] To ensure the cooperation between the upper template 22 and the lower template 21, a through hole 24 is provided in the upper template 22. A feed hole 25 matching the through hole 24 is provided on the lower template 21. And the lower end of the feed hole 25 communicates with the cavity 23. And a cylinder 2 26 is connected to the upper end of the frame 11. The output end of the cylinder 2 26 is fixedly connected to the upper end of the upper template 22 through a rod. A guide rod 27 is also connected to the frame 11. The upper template 22 moves up and down on the guide rod 27 through the cylinder 2 26.

[0022] To accelerate the cooling and forming of the screw, a cooling liquid groove 51 is also provided on the lower template 21. The cooling liquid groove 51 is arranged inside the lower template 21. And both ends of the cooling liquid groove 51 are respectively connected with a liquid inlet groove 52 and a liquid outlet groove 53. By injecting the cooling liquid through the liquid inlet groove 52, after cooling the side wall of the cavity 23 through the cooling liquid groove 51, it can be discharged through the liquid outlet groove 53, which can accelerate the forming speed without affecting the screw forming.

[0023] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
