[0012] As a further technical solution of the present invention, the fixed plate is fixedly installed on the inner side of the fixed base, an injector is movably installed at the lower part of the raw material box, the middle part of the lower end of the feed turntable is driven by a rotating rod, a round hole is provided in the middle part of the fixed plate for cooperating with the rotating rod, and a second roller is provided at the bottom of the lifting sleeve. The user places the injection mold on the upper end of the lifting sleeve, and uses the motor to cooperate with the gear structure to drive the rotating rod, so that the rotating rod drives the injection mold to rotate, and the injection mold is rotated to the bottom of the injector, and the mixed slurry is injected into the injection mold by the injector, and the position of the injection mold is adjusted by the rotation of the feed turntable, so that the injection mold is contacted with the discharge rack, and the discharge operation of the injection mold is completed by cooperating with the setting of the docking seat.

[0013] As a further technical solution of the present invention, the injector includes a lifting plate and an injection nozzle, the injection nozzle is fixedly installed in the middle of the lower end of the lifting plate, the lower end of the injection nozzle is located on both sides of the injection nozzle and limiting clamps are movably installed, and an injection tube is provided in the middle of the upper end of the lifting plate. The limiting clamp can be used to assist in fixing the injection mold when the injection nozzle performs high-pressure injection operation on the injection mold, thereby improving the stability of the injection mold, and the limiting clamp can be adaptively adjusted according to the size of the injection mold.

[0014] As a further technical solution of the present invention, the two groups of limit clamps are driven by a screw rod, and the screw rod and the injection nozzle are staggered. A motor used in conjunction with the screw rod is installed at one end of the lifting plate. The user uses the motor to drive the screw rod, so that the screw rod uses the threaded structure to simultaneously drive the limit clamp to move, thereby adjusting the position of the limit clamp plate so that the limit clamp plate is stuck on the side of the injection mold.

[0015] As a further technical solution of the present invention, a placing plate is fixedly installed on the outer surface of one side of the fixed base, and a discharge rack is arranged on the upper outer surface of the placing plate located on the upper part of the feed turntable.

[0016] As a further technical solution of the present invention, a guide rod is fixedly installed on the outer surface of one end of the discharge rack, and the side outer surface of the guide rod is inclined. A plurality of groups of first rollers are movably installed on the upper surface of the discharge rack. By utilizing the setting of the guide rod, when the injection mold rotates, the docking seat at the bottom of the injection mold can contact the guide rod. Through the inclined structure of the guide rod and the inclined structure of the side of the docking seat, the docking seat can be moved to one side, thereby guiding the docking seat to slide down on the top of the discharge rack.

[0017] As a further technical solution of the present invention, conical grooves are provided on the inner sides of the lower mold body and the combined mold, a grouting hole is provided in the middle of the combined mold, and the lower mold body and the combined mold are connected and fixed by a sealer. Because the lower mold body and the combined mold are designed as a double-layer structure, the double-layer injection operation of the lower mold body and the combined mold can be completed simultaneously by high-pressure grouting using an injector. The slurry can be introduced into the conical grooves of the lower mold body and the combined mold by the setting of the grouting holes and the guide grooves, thereby increasing the number of kiln tool vertebrae processed in the conical grooves.

Because the lower mold body and the combined mold use high-pressure grouting for feeding operations, and the lower mold body and the combined mold are gypsum mold structures, in order to improve the sealing performance of the lower mold body and the combined mold after the combination, a sealer is installed so that the sealer is stuck in the groove of the lower mold body and the combined mold to improve its sealing performance. At the same time, the sealer is made of rubber material. By setting the support frame, the structural strength of the sealer can be improved, so that the central structure can be better stuck into the groove.

[0019] As a further technical solution of the present invention, the inner sides of the lower mold body and the combined mold are provided with rectangular grooves, the interiors of the lower mold body and the combined mold are provided with guide grooves, the upper part of the raw material box is provided with a mixing rack, and a booster pump is installed inside the raw material box. The lower mold body and the combined mold can be provided with different types of mold groove structures, and the rectangular grooves can complete the processing operations of the cassette-type kiln.

[0020] A production method for a cordierite refractory kiln furniture preparation device comprises the following steps:

[0021] Step 1: pour the kiln furniture raw materials into the raw material box, add water and mix the raw materials using a mixing rack, assemble the lower mold body, the combined mold and the fixed top cover from bottom to top to assemble them into an injection mold, and install the injection mold on the circular notch of the feed turntable;

[0022] Step 2: Use the feed turntable to move the injection mold to the bottom of the injector, inject the mixed raw materials into the injection mold through the injector, and allow the raw materials to complete the kiln shaping operation in the injection mold. Use the discharge rack to take out the injection mold, disassemble the injection mold and take out the kiln. After drying the kiln, use the kiln to complete the sintering and shaping of the kiln.

[0023] Beneficial effects of the present invention:

[0024] 1. By setting a material discharging rack and a material feeding turntable, when the preparation device of the cordierite refractory kiln furniture is used, it has a rotary material injection auxiliary structure, and can automatically complete the material taking operation of the mold structure, thereby improving the material injection processing efficiency of the cordierite refractory kiln furniture;

[0025] During operation, the user places the injection mold on the upper end of the lifting sleeve. The lifting sleeve can cooperate with the arc-shaped top block to lift and lower the injection mold when the feed turntable rotates. The motor cooperates with the gear structure to drive the rotating rod, so that the rotating rod drives the injection mold to rotate, and the injection mold is rotated to the bottom of the injector. The mixed slurry is injected into the injection mold by the injector. The position of the injection mold is adjusted by the rotation of the feed turntable. During the rotation of the feed turntable, the second roller at the bottom of the lifting sleeve is in contact with the arc-shaped top block, and the surface of the arc-shaped top block is arc-shaped. The structure allows the arc-shaped top block to gradually lift the lifting sleeve upward when the feed turntable rotates, thereby creating a gap between the docking card seat and the feed turntable. By utilizing the setting of the guide rod, when the injection mold rotates, the gap can be matched to make the docking card seat at the bottom of the injection mold contact with the guide rod. Through the inclined structure of the guide rod and the inclined structure of the side of the docking card seat, the docking card seat is moved to one side, thereby guiding the docking card seat to slide above the discharge rack, thereby making the injection mold contact with the discharge rack, and matching the setting of the docking card seat to complete the discharge operation of the injection mold.

[0026] 2. By setting up the injection mold and the sealer, when the preparation device of the cordierite refractory kiln furniture is used, the processing operation of multiple groups of different types of kiln furniture can be completed by the high-pressure grouting method, and at the same time, the sealing performance of the gypsum mold structure after assembly is improved to prevent the slurry from overflowing;

[0027] Because the lower mold body and the combined mold are fed with materials by high-pressure grouting, and the lower mold body and the combined mold are gypsum mold structures, in order to improve the sealing performance of the lower mold body and the combined mold after being combined, a sealer is installed so that the sealer is stuck in the groove of the lower mold body and the combined mold to improve its sealing performance. At the same time, the sealer is made of rubber material. By setting the support frame, the structural strength of the sealer can be improved, so that the central structure can be better stuck in the groove. The injector can simultaneously complete the double-layer injection operation of the lower mold body and the combined mold by high-pressure grouting. The grouting hole is combined with the guide groove to guide the slurry into the conical groove of the lower mold body and the combined mold, thereby increasing the number of kiln vertebrae processed in the conical groove. Secondly, the lower mold body and the combined mold can be set with different types of mold groove structures, and the rectangular groove can complete the processing operation of the cassette type kiln. The lower mold body and the combined mold can be set with different types of mold groove structures, and the rectangular groove can complete the processing operation of the cassette type kiln, thereby improving its scope of application.

[0028] 3. By setting the injector and the limit clamp, when the preparation device of the cordierite refractory kiln furniture is used, the use of the injection mold can be optimized, the accuracy of the injection mold during the grouting operation can be improved, and the dislocation of the injection mold can be avoided, and injection molds of different sizes can be applied;

[0029] During operation, the limit clamp can be used to assist in fixing the injection mold when the injection nozzle performs high-pressure injection on the injection mold, thereby improving the stability of the injection mold. At the same time, the limit clamp can be adaptively adjusted according to the size of the injection mold. The motor is used to drive the screw rod, so that the screw rod uses the threaded structure to simultaneously drive the limit clamp plate to move, thereby adjusting the position of the limit clamp plate, so that the limit clamp plate is stuck on the side of the injection mold, thereby completing the limit fixation of the injection mold.

[0042] In order to solve the problem of automatic loading and unloading during kiln processing, Figure 2 As shown, the fixed plate 11 is fixedly installed on the inner side of the fixed base 1, the lower part of the raw material box 6 is movably installed with an injector 7, the lower middle part of the feed turntable 4 is driven by a rotating rod 9, the middle part of the fixed plate 11 is provided with a round hole used in conjunction with the rotating rod 9, and the bottom of the lifting sleeve 21 is provided with a second roller 20. The user places the injection mold 8 on the upper end of the lifting sleeve 21, and uses a motor and a gear structure to drive the rotating rod 9, so that the rotating rod 9 drives the injection mold 8 to rotate, and the injection mold 8 is rotated to the bottom of the injector 7, and the mixed slurry is injected into the injection mold 8 by the injector 7. The position of the injection mold 8 is adjusted by the rotation of the feed turntable 4, so that the injection mold 8 is in contact with the discharge rack 3, and the discharge operation of the injection mold 8 is completed in conjunction with the setting of the docking seat 22.

[0043] like Figure 3 As shown, the injector 7 includes a lifting plate 16 and an injection nozzle 14. The injection nozzle 14 is fixedly installed in the middle of the lower end of the lifting plate 16. The lower end of the injection nozzle 14 is located on both sides of the injection nozzle 14 and a limiting clamp 13 is movably installed. An injection tube 17 is provided in the middle of the upper end of the lifting plate 16. The limiting clamp 13 can assist in fixing the injection mold 8 when the injection nozzle 14 performs high-pressure injection operation on the injection mold 8, thereby improving the stability of the injection mold 8. At the same time, the limiting clamp 13 can be adaptively adjusted according to the size of the injection mold 8.

[0044] The two sets of limit clamps 13 are driven by a screw rod 15, and the screw rod 15 and the injection nozzle 14 are staggered. A motor for use with the screw rod 15 is installed at one end of the lifting plate 16. The user uses the motor to drive the screw rod 15, so that the screw rod 15 uses the threaded structure to simultaneously drive the limit clamp 13 to move, thereby adjusting the position of the limit clamp 13 so that the limit clamp 13 is stuck on the side of the injection mold 8.

[0045] In order to solve the problem of automatic loading and unloading during kiln processing, Figure 4 As shown, a storage tray 2 is fixedly mounted on the outer surface of one side of the fixed base 1, and a discharge rack 3 is arranged on the upper outer surface of the storage tray 2 located on the upper part of the feed turntable 4. The entire body of the discharge rack 3 is arranged at an angle. Through the arrangement of the discharge rack 3, the material removal operation of the injection mold 8 can be completed during the rotation and movement of the injection mold 8, so that the injection mold 8 can be removed from the feed turntable 4.

[0046] like Figure 4 As shown, a guide rod 19 is fixedly installed on the outer surface of one end of the discharge rack 3, and the side outer surface of the guide rod 19 is inclined. A plurality of groups of first rollers 18 are movably installed on the upper surface of the discharge rack 3. By utilizing the setting of the guide rod 19, when the injection mold 8 rotates, the docking seat 22 at the bottom of the injection mold 8 can be brought into contact with the guide rod 19. Through the inclined structure of the guide rod 19 and the inclined structure of the side of the docking seat 22, the docking seat 22 can be moved to one side, thereby guiding the docking seat 22 to slide down on the top of the discharge rack 3.

[0047] In order to solve the injection problem during multi-layer kiln processing, Figure 5 As shown, the inner sides of the lower mold body 23 and the combined mold 24 are both provided with a conical groove 25, and the middle part of the combined mold 24 is provided with a grouting hole 26. The lower mold body 23 and the combined mold 24 are connected and fixed by a sealer 28. Because the lower mold body 23 and the combined mold 24 are designed as a double-layer structure, the injection device 7 can simultaneously complete the double-layer injection operation of the lower mold body 23 and the combined mold 24 by high-pressure grouting. The grouting hole 26 cooperates with the setting of the guide groove to guide the slurry into the conical groove 25 of the lower mold body 23 and the combined mold 24, and the conical groove 25 is lifted. Figure 8 The number of kiln tool cones 31 that have been processed is shown.

[0048] like Figure 6 As shown, the sealer 28 is a frame structure as a whole, a support frame 29 is fixedly installed on the inner side of the sealer 28, and the cross-section of the sealer 28 is a W-shaped structure, and the lower mold body 23, the combined mold 24 and the fixed top cover 27 are all provided with grooves for cooperating with the sealer 28. Because the lower mold body 23 and the combined mold 24 use high-pressure grouting for feeding operations, and the lower mold body 23 and the combined mold 24 are gypsum mold structures, in order to improve the sealing performance of the lower mold body 23 and the combined mold 24 after the combination, the sealer 28 is installed so that the sealer 28 is stuck in the groove of the lower mold body 23 and the combined mold 24 to improve its sealing performance. At the same time, the sealer 28 is made of rubber material. By setting the support frame 29, the structural strength of the sealer 28 can be improved, so that the central structure thereof can be better stuck in the groove.

[0049] like Figure 7As shown, the inner sides of the lower mold body 23 and the combined mold 24 are both provided with rectangular grooves 30, the interiors of the lower mold body 23 and the combined mold 24 are both provided with guide grooves, a mixing rack 5 is provided on the upper part of the raw material box 6, and a booster pump is installed inside the raw material box 6. The lower mold body 23 and the combined mold 24 can be provided with different types of mold groove structures, and the rectangular groove 30 can complete the processing operation of the cassette type kiln.

[0050] The production method of the cordierite refractory kiln furniture manufacturing device of this embodiment comprises the following steps:

[0051] Step 1: kiln furniture raw materials include cordierite substrate, mullite particles, binder and plasticizer. The kiln furniture raw materials are poured into the interior of the raw material box 6, and after adding water, the raw materials are mixed and stirred using the mixing rack 5. The lower mold body 23, the combined mold 24 and the fixed top cover 27 are assembled from bottom to top to form an injection mold 8, and the injection mold 8 is installed on the circular notch 12 of the feed turntable 4;

[0052] Step 2: Use the feeding turntable 4 to move the injection mold 8 to the bottom of the injector 7, inject the mixed raw materials into the injection mold 8 through the injector 7, and complete the kiln furniture shaping operation in the injection mold 8. Use the discharge rack 3 to take out the injection mold 8, disassemble the injection mold 8 and take out the kiln furniture, dry the kiln furniture, and then use the kiln to complete the sintering and shaping of the kiln furniture.

[0053] During operation, the above equipment does not have a rotating feeding structure. The kiln is shaped by injecting materials into the mold, and the loading and unloading operations of the mold need to be done manually. The kiln injection processing operation cannot be completed continuously, which reduces its work efficiency.

[0054] To this end, by providing a discharge rack 3 and a feed turntable 4, when the preparation device of the cordierite refractory kiln furniture is used, it has a rotary injection auxiliary structure, and can automatically complete the material taking operation of the mold structure, thereby improving the injection processing efficiency of the cordierite refractory kiln furniture;

[0055] The user places the injection mold 8 on the upper end of the lifting sleeve 21. The lifting sleeve 21 can cooperate with the arc-shaped top block 10 to lift and lower the injection mold 8 when the feed turntable 4 rotates. The motor cooperates with the gear structure to drive the rotating rod 9, so that the rotating rod 9 drives the injection mold 8 to rotate, and the injection mold 8 is rotated to the bottom of the injector 7. The mixed slurry is injected into the injection mold 8 by the injector 7. The position of the injection mold 8 is adjusted by the rotation of the feed turntable 4. During the rotation of the feed turntable 4, the second roller 20 at the bottom of the lifting sleeve 21 is in contact with the arc-shaped top block 10, and the surface of the arc-shaped top block 10 is an arc-shaped structure. The arc-shaped top block 10 can gradually lift the lifting sleeve 21 upward when the feed turntable 4 rotates, so that a gap is generated between the docking seat 22 and the feed turntable 4. By using the setting of the guide rod 19, when the injection mold 8 rotates, the gap is matched to make the docking seat 22 at the bottom of the injection mold 8 contact with the guide rod 19. Through the inclined structure of the guide rod 19 and the inclined structure of the side of the docking seat 22, the docking seat 22 is moved to one side, so that the docking seat 22 is guided to the top of the discharge rack 3 and slides down, so that the injection mold 8 contacts the discharge rack 3, and the setting of the docking seat 22 is matched to complete the discharge operation of the injection mold 8.

[0056] Secondly, according to the type of porcelain being fired, kiln tools can be divided into various structures such as pills, cakes, discs and cones, while the above equipment can only complete the processing operation of one type of kiln tool at a time, and the number of single processing is limited, which reduces its processing flexibility and efficiency;

[0057] To this end, by providing the injection mold 8 and the sealer 28, when the preparation device of the cordierite refractory kiln furniture is used, the processing operation of multiple groups of different types of kiln furniture can be completed by the high-pressure grouting method, and at the same time, the sealing performance of the gypsum mold structure after assembly is improved to prevent the slurry from overflowing;

[0058] Because the lower mold body 23 and the combined mold 24 are fed with materials by high-pressure grouting, and the lower mold body 23 and the combined mold 24 are gypsum mold structures, in order to improve the sealing performance of the lower mold body 23 and the combined mold 24 after being combined, a sealer 28 is installed so that the sealer 28 is stuck in the groove of the lower mold body 23 and the combined mold 24 to improve its sealing performance. At the same time, the sealer 28 is made of rubber material. By setting the support frame 29, the structural strength of the sealer 28 can be improved, so that the middle structure thereof can be better stuck in the groove. The injector 7 can be used to simultaneously The double-layer injection operation of the lower mold body 23 and the combined mold 24 is completed at the same time. The slurry can be introduced into the conical groove 25 of the lower mold body 23 and the combined mold 24 through the setting of the grouting hole 26 and the guide groove, and the processing number of the kiln vertebra 31 in the conical groove 25 is increased. Secondly, the lower mold body 23 and the combined mold 24 can be provided with different types of mold groove structures, and the rectangular groove 30 can complete the processing operation of the cassette type kiln. The lower mold body 23 and the combined mold 24 can be provided with different types of mold groove structures, and the rectangular groove 30 can complete the processing operation of the cassette type kiln, thereby improving its application range;

[0059] Secondly, kiln furniture is mainly processed by mold processing and grouting to complete its shaping operation, but the automatic grouting operation is prone to misalignment during the docking process, causing slurry overflow and resulting in waste of raw materials;

[0060] To this end, by providing the injector 7 and the limiting clamp 13, when the preparation device of the cordierite refractory kiln furniture is used, the use of the injection mold 8 can be optimized, the accuracy of the injection mold 8 during the grouting operation can be improved, and the dislocation phenomenon of the injection mold 8 can be avoided, and injection molds 8 of different sizes can be applied;

[0061] During operation, the limiting clamp 13 can be used to assist in fixing the injection mold 8 when the injection nozzle 14 performs high-pressure injection on the injection mold 8, thereby improving the stability of the injection mold 8. At the same time, the limiting clamp 13 can be adaptively adjusted according to the size of the injection mold 8, and the motor is used to drive the screw rod 15, so that the screw rod 15 uses the threaded structure to simultaneously drive the limiting clamp 13 to move, thereby adjusting the position of the limiting clamp 13, so that the limiting clamp 13 is stuck on the side of the injection mold 8, thereby completing the limiting fixation of the injection mold 8.
