[0024] The venting mechanism is located above the demolding mechanism.

[0025] To prevent cavities from forming inside the nozzle after pouring, the refractory material inside the mold is mixed in layers, and an venting mechanism is installed, such as... Figures 1-4 The exhaust mechanism mixes the refractory material in layers during the pouring process at the burner nozzle, thus achieving the pouring and exhausting action.

[0029] Furthermore, the electric lifting rod 206 at the top of the mixing drum 203 drives the lifting slide plate 207 to slide along the surface of the lifting slide groove 205, and drives the mixing rod 210 to perform layered mixing of the casting material through the connecting rod 208 and the connecting plate 209.

[0030] To facilitate ejection and demolding after the material has solidified and formed in the nozzle, a demolding mechanism is provided, such as... Figures 1-3 and Figure 5 The demolding mechanism taps the outer surface of the mold after the burner nozzle is cast, thus demolding the mold.

[0031] The demolding mechanism includes a flip plate 3, with flipping shafts 301 fixedly connected to both ends of the flip plate 3. The surfaces of the two flipping shafts 301 are rotatably connected to the surface of the worktable 1. A positioning plate 302 is fixedly connected to the lower surface of the flip plate 3. The two positioning plates 302 are symmetrically distributed with the axis in the width direction of the flip plate 3 as the center. The surface of the positioning plate 302 is slidably connected to the surface of the worktable 1.

[0032] Furthermore, the flipping position of the flipping plate 3 is positioned by two positioning plates 302 set on one side of the flipping plate 3, so that the casting mold 2 is in a horizontal position during casting.

[0033] The surface of the flip plate 3 is provided with a movable groove 303. The surfaces of the casting mold 2 and the limiting plate 202 are slidably connected to the surface of the flip plate 3. The surface of the movable slider 201 is slidably connected to the surface of the movable groove 303. The surface of the worktable 1 is rotatably connected to the flip worm 304 through the support frame. The upper end of the flip worm 304 is fixedly connected to the handwheel 305. The surface of the flip worm 304 is drivenly connected to the flip turbine 306. The surface of the flip turbine 306 is fixedly connected to one end of the flip shaft 301.

[0034] Furthermore, the flipping worm 304 is connected to the flipping turbine 306 to limit the flipping angle of the flipping plate 3, thereby maintaining the stability of the casting mold 2.

[0035] A vibrating cylinder 307 is fixedly connected to the surface of the flip plate 3. Two vibrating cylinders 307 are symmetrically distributed around the axis of the width direction of the flip plate 3. A vibrating push plate 308 is fixedly connected to the output end of the vibrating cylinder 307. A guide rod 309 is slidably connected to the surface of the vibrating push plate 308. Two guide rods 309 are symmetrically distributed around the axis of the width direction of the vibrating push plate 308. Limiting blocks 310 and curved panels 311 are fixedly connected to the two ends of the guide rods 309, respectively. A shock-absorbing spring 312 is provided on the outside of the guide rods 309. The two ends of the shock-absorbing spring 312 are elastically connected to the surface of the vibrating push plate 308 and the surface of the curved panel 311, respectively. The surface of the curved panel 311 is slidably connected to the surface of the movable slide 303 and the surface of the casting mold 2, respectively.

[0036] Furthermore, vibration cylinders 307 are installed on both sides of the flip plate 3. Through vibration push plate 308, guide rod 309, shock absorber spring 312 and curved plate 311, the casting mold moves along the length direction of the moving slide 303 to vibrate and beat the casting material inside the casting mold 2.

[0037] By setting up an exhaust mechanism and a demolding mechanism, the exhaust mechanism mixes the casting material in layers during the pouring process at the burner nozzle, expelling air from the inside of the two casting molds to prevent stratification. The demolding mechanism taps the outer surface of the mold after the casting is formed at the burner nozzle, making it easy to flip and demold. This solves the technical problem that existing burners require manual vibration and flipping for demolding during mold pouring.

[0038] Working principle:

[0039] Before use, the casting material is fed into the casting mold 2 from above through the guide pipe. The stirring motor 204 located below the casting mold 2 drives the stirring drum 203 located at the center of the casting mold 2 to rotate. The stirring drum 203 drives the connecting rods 208, connecting plates 209, and stirring rods 210 on both sides to rotate via the lifting slide plate 207. The multiple stirring rods 210 stir the casting material filled inside the casting mold 2, expelling the air when the casting material is poured in. At the same time, the electric lifting rod 206 located at the top of the stirring drum 203 is driven. The electric lifting rod 206 drives the lifting slide plate 207 to move along the lifting groove 2 on the surface of the stirring drum 203. 05 moves upward, driving the stirring rod 210 to stir the upper layer of the casting material until the casting material is filled. After the casting material is filled, the vibrating cylinder 307 of the demolding mechanism drives the curved plate 311 to vibrate and beat the surface of the casting mold 2, further expelling the cavities inside the casting material. After the casting material is allowed to solidify, the handwheel 305 on one side of the worktable 1 drives the rotating worm gear 304 to rotate. The rotating worm gear 304 is connected to the surface of the rotating turbine 306, driving the rotating shaft 301 on the surface of the rotating turbine 306 to rotate. Both ends of the rotating plate 3 are rotatably connected to the surface of the worktable 1 through the rotating shaft 301. The casting mold 2, positioned above the flip plate 3, flips over. Two positioning plates 302 on one side of the flip plate 3 are slidably connected to the surface of the worktable 1, positioning the casting angle and demolding angle of the flip plate 3. When the casting mold 2, positioned above the flip plate 3, flips to below the worktable 1, it drives the vibration cylinders 307 on both sides of the flip plate 3. The output end of the vibration cylinders 307 drives the vibration push plate 308 to move. The surface of the vibration push plate 308 is elastically connected to the surface of the curved panel 311 through a shock-absorbing spring 312. The surface of the curved panel 311 is slidably connected to the surface of the vibration push plate 308 through a guide rod 309. The surface of the curved panel 311 is in contact with the surface of the vibration push plate 308. The sliding groove 303 on the surface of the flip plate 3 is slidably connected, and the casting mold is moved by the curved plate 311. The limiting block 310 at the rear end of the guide rod 309 prevents the guide rod 309 from disengaging from the vibrating push plate 308 when the shock-absorbing spring 312 pushes the curved plate 311 towards the casting mold. The curved plates 311 on both sides of the casting mold 2 push the casting mold 2 to move back and forth in sequence, which facilitates the demolding of the solidified nozzle inside the casting mold 2. The sliding block 201 below the casting mold slides along the surface of the sliding groove 303. The limiting plate 202 at the lower end of the sliding block 201 limits the casting mold 2 to prevent it from falling off after the casting mold flips.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
