Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 5 As shown, the present invention provides the following technical solutions: a manufacturing device for integrally combining a metal spectacle frame and accessories, including a body 1. A lower mold 2 and an upper mold 10 are installed on the top of the body 1. A positioning device is movably connected between the lower mold 2 and the upper mold 10. A detachable inner mold 18 is installed in the lower mold 2. Two frame grooves 181 and a bridge groove 182 are formed in the inner mold 18. Frames 19 are placed in both of the two frame grooves 181. The bridge groove 182 is communicated with the two frame grooves 181. A cooling device is further provided in the lower mold 2, and the cooling device is arranged at the bottom of the inner mold 18;

[0023] A cover plate is arranged at the top of the bridge groove 182, and a liquid injection hole 183 is formed in the cover plate;

[0024] A heating device is arranged inside the upper mold 10. The heating device is set as at least two heating pipes 20. And an injection device 5 and a driving device are installed on the top of the upper mold 10. And a hopper 7 is installed on one side of the injection device 5. The injection device 5 includes an injection system of an injection molding machine, which is a publicly known technical means and will not be elaborated here.

[0025] An installation groove 21 is formed in the lower mold 2. The inner mold 18 and the cooling device are both arranged in the installation groove 21. The inner mold 18 is set as detachable, so as to facilitate replacing the inner mold 18 according to different shapes and sizes of glasses. The cooling device includes a cooling water pipe 13. A water outlet 131 and a water inlet 132 are arranged on the cooling water pipe 13. Both the water outlet 131 and the water inlet 132 extend to the outside of the lower mold 2;

[0026] The cooling device further includes a water storage bucket 14, a refrigeration device 15, and a water pump 16. The water outlet 131 is connected to the water storage bucket 14 through a water outlet pipe.

A water inlet pipe 17 is connected between the outlet of the water pump 16 and the water inlet 132. A circulation pump and a circulation water pipe are connected between the water storage bucket 14 and the refrigeration device 15, facilitating the pumping of the used cooling water in the water storage bucket 14 into the refrigeration device 15 for recycling.

[0027] Regarding the above, when using the manufacturing equipment for the integrated combination of the metal spectacle frame and accessories, first, the fused metal liquid is placed into the hopper 7. The hopper 7 is connected to the injection device 5, so the metal liquid enters the injection device 5. The manufactured spectacle frame 19 is placed in the spectacle frame groove 181 on the inner mold 18. At this time, the driving device is started, and the injection device 5 is driven by the driving device to move downward. The injection device 5 injects the metal liquid into the bridge groove 182 and flows from the bridge groove 182 to be connected to the spectacle frame 19. After injection, the injection device 5 retracts, and the upper mold 10 is pushed by the driving device to make the upper mold 10 and the lower mold 2 close. The heating tube 20 in the upper mold 10 is turned on, and the metal liquid is heated by the heating tube 20 to make the metal liquid more uniform. After the heat treatment, the upper mold 10 moves away from the lower mold 2, and then the water pump 16 pumps the cooling water in the refrigeration device 15 into the cooling water pipe 13 through the water inlet pipe 17. The cooling water cools the injection-molded mold in the inner mold 18, accelerating the connection and molding of the bridge and the spectacle frame, thereby completing the integrated production of the metal spectacle frame and the bridge of the accessory.
