[0020] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a cermet shell forming device includes a lower die base 1 and an upper die base 2. A forming groove 3 is provided on the lower die base 1, and a forming convex block 4 is fixedly arranged on the upper die base 2. The forming convex block 4 is inserted into the forming groove 3. A support base 5 is arranged below the lower die base 1, and a material loosening and mold pushing assembly is arranged on the support base 5. The material loosening and mold pushing assembly is used to vibrate and loosen the raw materials formed in the forming groove 3 and can push the model formed in the forming groove 3 out of the forming groove 3.

[0021] The loose material pushing die assembly includes a hydraulic telescopic device 6 fixedly arranged on the support base 5.

A plurality of the ejector rods 10 are provided, and the ejector rods 10 all pass through the lower die base 1 and extend into the forming groove 3 on the lower die base 1. The top end of the ejector rod 10 is fixedly provided with a push plate 11. The push plate 11 is located in the forming groove 3, and the size of the push plate 11 is adapted to the size of the forming groove 3. A clamping and fixing assembly is arranged on the upper die base 2, and the clamping and fixing assembly is used for clamping the injection pipe for injecting raw materials into the forming groove 3 on the fixing plate 9.

[0022] In this embodiment, when injecting the forming raw materials into the forming groove 3, the vibration motor 8 is started. The start of the vibration motor 8 drives the ejector rod 10 to vibrate. The vibration of the ejector rod 10 drives the vibration of the push plate 11. The vibration of the push plate 11 will vibrate the raw materials added into the forming groove 3. When the raw materials in the forming groove 3 are filled, the lower die base 1 and the upper die base 2 are separated. Then the hydraulic telescopic device 6 is started. The start of the hydraulic telescopic device 6 pushes the shock-absorbing support plate 7 to move upward. The movement of the shock-absorbing support plate 7 drives the vibration motor 8 to move. The movement of the vibration motor 8 drives the fixing plate 9 to move. The movement of the fixing plate 9 drives the ejector rod 10 on the fixing plate 9 to move. The movement of the ejector rod 10 drives the push plate 11 to move. The movement of the push plate 11 will push out the injection-molded metal ceramic shell from the forming groove 3. Then the injection-molded metal ceramic shell can be collected.

[0023] Through the setting of the loose material pushing die assembly, not only can the injected raw materials be loosened, so as to accelerate the filling of the gaps between the injected raw materials in the forming groove 3, thereby accelerating the injection of the injected raw materials and further improving the injection molding efficiency of the metal ceramic shell, but also the injection-molded parts can be ejected from the forming groove 3, so as to reduce the labor force for manually taking out the injection-molded parts from the forming groove 3, and further effectively improve the taking-out efficiency of the injection-molded parts of the metal ceramic shell.

[0024] The clamping and fixing assembly includes a plurality of limit rods 12 fixedly arranged on the upper mold base 2 and a rotating ring 13 located above the upper mold base 2, a plurality of limit grooves 14 are opened on the rotating ring 13, and the plurality of limit rods 12 are respectively slidably arranged in the plurality of limit grooves 14, a clamping plate 15 is rotatably arranged in the rotating ring 13 through a connecting arm 21, and the clamping plate 15 is rotatably connected to the upper mold base 2, and a plurality of the clamping plates 15 are arranged in sequence. A transmission tooth 16 is fixedly provided on the outer wall surface of the rotating ring 13, and a transmission wheel 17 is provided on one side of the rotating ring 13. The transmission wheel 17 is meshed with the transmission tooth 16, and the transmission wheel 17 is rotatably connected to the upper mold base 2. A knob 20 is fixedly provided on the transmission wheel 17, and an injection hole 18 is opened on the upper mold base 2. The injection hole 18 passes through the upper mold base 2 and the molding protrusion 4 on the upper mold base 2 and communicates with the molding groove 3 on the lower mold base 1. A pad 19 is fixedly provided on the upper mold base 2, the limit rod 12 is connected to the pad 19, and the transmission wheel 17 is rotatably connected to the pad 19.

[0025] In this embodiment, the injection molding material is first connected to the injection molding hole 18 through the injection molding tube, and then the knob 20 is rotated. The rotation of the knob 20 drives the transmission wheel 17 to rotate, and the rotation of the transmission wheel 17 drives the rotating ring 13 to rotate. The rotation of the rotating ring 13 drives the clamping plate 15 to rotate. When the clamping plate 15 is placed on the top of the connection notch on the injection molding tube, the rotation of the knob 20 is stopped, and then the injection molding material is injected into the injection molding hole 18 through the injection molding tube. The injection molding material in the injection molding hole 18 is injected into the molding groove 3 for molding. The position of the injection molding tube docking with the injection molding hole 18 can be limited by the setting of the clamping and fixing assembly, so that the injection molding tube will not be separated from the injection molding hole 18 when the raw material is injected into the injection molding hole 18, thereby improving the stability of the connection between the injection molding hole 18 and the injection molding tube.

[0026] The working principle of the utility model is:

[0027] First, connect the injection molding raw material to the injection hole 18 through the injection molding pipe. Then, rotate the knob 20. The rotation of the knob 20 drives the driving wheel 17 to rotate. The rotation of the driving wheel 17 drives the rotating ring 13 to rotate. The rotation of the rotating ring 13 drives the clamping plate 15 to rotate. When the clamping plate 15 abuts against the connection notch on the injection molding pipe, stop rotating the knob 20. Then, inject the injection molding raw material into the injection hole 18 through the injection molding pipe. The injection molding raw material in the injection hole 18 is injected into the molding groove 3 for molding. When injecting the molding raw material into the molding groove 3, start the vibration motor 8. The start of the vibration motor 8 drives the ejector rod 10 to vibrate. The vibration of the ejector rod 10 drives the vibration of the push plate 11. The vibration of the push plate 11 will vibrate the raw material added to the molding groove 3. When the raw material in the molding groove 3 is filled, separate the lower mold base 1 from the upper mold base 2. Then, start the hydraulic telescopic device 6. The start of the hydraulic telescopic device 6 pushes the shock-absorbing support plate 7 to move upward. The movement of the shock-absorbing support plate 7 drives the vibration motor 8 to move. The movement of the vibration motor 8 drives the fixed plate 9 to move. The movement of the fixed plate 9 drives the ejector rod 10 on the fixed plate 9 to move. The movement of the ejector rod 10 drives the push plate 11 to move. The movement of the push plate 11 will push out the ceramic-metal shell after injection molding from the molding groove 3. Then, collect the ceramic-metal shell after injection molding.
