Description

Technical Field

[0001] This utility model relates to the field of alumina hollow sphere brick manufacturing technology, specifically to an alumina hollow sphere molding die device with vibration and pressure function. Background Technology

[0002] Hollow alumina spheres are a new type of high-temperature insulation material. They are made by melting and blowing industrial alumina in an electric furnace, and the crystal form is α-Al₂O₃ microcrystals. Using hollow alumina spheres as the main body, various shapes can be made. The maximum service temperature is 1800℃. The products have high mechanical strength, several times that of general lightweight products, while the bulk density is only half that of corundum products. Hollow alumina sphere bricks can be made from hollow alumina spheres and alumina powder as the main raw materials, combined with other binders, and fired at 1750℃. It belongs to the category of ultra-high temperature energy-saving insulation materials.

[0003] The mainstream process for manufacturing alumina hollow sphere bricks generally involves mixing alumina hollow spheres with a binder to form a blank, then loading a certain amount of the blank into a metal mold. A hydraulic press is then used to press the blank a certain distance to achieve the desired shape. However, this method of pressing alumina hollow sphere bricks typically involves directly using a hydraulic device to press the blank inside the metal mold. This method can easily lead to the alumina spheres being too close together and flattened. Conversely, if the pressure applied by the hydraulic press is too low, the bricks may become loose, affecting their quality.

[0004] To address this, we propose a molding device for forming hollow alumina spheres with vibration and pressure functions. Utility Model Content

[0005] The purpose of this invention is to provide an alumina hollow sphere forming mold device with vibration and pressure function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an alumina hollow sphere molding die device with vibration and pressurization function, comprising a support frame, a molding cavity mounted on the upper part of the support frame, a molding component mounted on the upper part of the support frame, the molding component being used to press and mold the material inside the molding cavity, the molding component being able to prevent damage during the pressing and molding of the material inside the molding cavity, and a vibration component mounted inside the support frame, the vibration component being used to vibrate and pressurize the material inside the molding cavity during the pressing and molding of the material, the vibration component being able to prevent material accumulation during the pressing and molding of the material inside the molding cavity.

[0007] Preferably, the molding assembly includes a support frame, which is fixedly connected to the top of a support frame. A hydraulic cylinder is fixedly installed on the upper surface of the support frame. Several spring cavities are fixedly connected to the bottom surface of the support frame. A support spring is fixedly connected to the bottom wall of each spring cavity. The other end of each support spring is fixedly connected to the bottom surface of the molding cavity.

[0008] Preferably, guide rods are fixedly connected to both the left and right sides of the molding cavity, and each guide rod is engaged with the support frame.

[0009] Preferably, the position of the hydraulic cylinder output port corresponds to the position of the upper surface of the molding cavity.

[0010] Preferably, the vibration assembly includes a drive motor, which is fixedly connected to the bottom wall of the support frame. The output shaft of the drive motor is fixedly connected to a fixed disk. Several fixed balls distributed in a circle are fixedly connected to the upper surface of the fixed disk. Several slots are opened on the upper surface of the support frame. An impact rod is engaged inside each slot. A fixed plate is fixedly connected to the bottom surface of each impact rod. An impact ball is fixedly connected to the bottom surface of each fixed plate.

[0011] Preferably, the positions of the fixed balls and the positions of the impacting balls are located on the same circumference.

[0012] Preferably, each of the fixed plates is fixedly connected to a set of elastic steel plates between itself and the top wall of the support frame.

[0013] Preferably, after the impact rod is installed, there is a certain gap between it and the upper surface of the support frame.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. When making alumina hollow spherical bricks, first, a certain amount of various materials are put into the mold cavity. Then, the power switch connected to the hydraulic cylinder is turned on to lower the output shaft of the hydraulic cylinder. At this time, the upper mold fixed by the output shaft of the hydraulic cylinder will enter the mold cavity to press the material inside the mold cavity. The mold cavity will descend stably through the guidance of the guide rod. At this time, the support spring will contract and apply a reaction force to the mold cavity, which can better press and shape the material inside the mold cavity.

[0016] By setting up the molding components, the molding cavity can be cushioned by the supporting springs when the material is pressed and molded, thus preventing the material from being crushed.

[0017] 2. When the bottom surface of the molding cavity is pressed close to the upper surface of the support frame, the power switch connected to the drive motor is turned on, causing the output shaft of the drive motor to rotate. At this time, the fixed disc fixed to the output shaft of the drive motor will rotate synchronously. The fixed ball will collide with the impact ball. Since both the fixed ball and the impact ball are circular, when the fixed ball and the impact ball collide, the impact ball will cause the fixed plate and the impact rod to rise. At this time, the top surface of the impact rod will impact the bottom surface of the molding cavity. As the fixed disc continues to rotate, it will continue to impact the bottom surface of the molding cavity.

[0018] By setting up a vibration component, when the impact rod vibrates and impacts the bottom surface of the molding cavity, the material inside the molding cavity can be pressed more compactly, and the accumulation of hollow alumina spheres can be avoided, which would cause the material to be crushed and affect the quality of the finished product.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] Example 1: An alumina hollow sphere molding die device with vibration and pressure function includes a support frame 3, a molding cavity 5 installed above the support frame 3, a molding component 1 installed above the support frame 3, the molding component 1 being used to press and mold the material inside the molding cavity 5, the molding component 1 being able to prevent damage during the pressing and molding of the material inside the molding cavity 5, and a vibration component 2 installed inside the support frame 3, the vibration component 2 being used to vibrate and pressurize during the pressing and molding of the material inside the molding cavity 5, the vibration component 2 being able to prevent material accumulation during the pressing and molding of the material inside the molding cavity 5.

[0027] The molding component 1 includes a support frame 4, which is fixedly connected above the support frame 3. A hydraulic cylinder 9 is fixedly installed on the upper surface of the support frame 4. Several spring cavities 8 are fixedly connected to the bottom surface of the support frame 3. A support spring 7 is fixedly connected to the bottom wall of each spring cavity 8. The other end of each support spring 7 is fixedly connected to the bottom surface of the molding cavity 5.

[0028] Guide rods 6 are fixedly connected to both the left and right sides of the molding cavity 5, and each guide rod 6 is engaged with the support frame 4.

[0029] The position of the output port of hydraulic cylinder 9 corresponds to the position of the upper surface of the forming mold cavity 5.

[0030] When making alumina hollow spherical bricks, a certain amount of various materials are first placed into the mold cavity 5. Then, the power switch connected to the hydraulic cylinder 9 is turned on, causing the output shaft of the hydraulic cylinder 9 to descend. At this time, the upper mold fixed by the output shaft of the hydraulic cylinder 9 will enter the mold cavity 5 to press the material inside the mold cavity 5. At this time, the mold cavity 5 will descend stably through the guidance of the guide rod 6. At this time, the support spring 7 will contract and apply a reaction force to the mold cavity 5, which can better press and shape the material inside the mold cavity 5.

[0031] By setting the molding component 1, the molding cavity 5 can be cushioned by the support spring 7 when the material is pressed and molded, thus preventing the material from being crushed.

[0032] In embodiment 2, the vibration component 2 includes a drive motor 10, which is fixedly connected to the bottom wall of the support frame 3. The output shaft of the drive motor 10 is fixedly connected to a fixed disk 11. Several fixed balls 12 arranged in a circular pattern are fixedly connected to the upper surface of the fixed disk 11. Several slots 13 are opened on the upper surface of the support frame 3. An impact rod 14 is engaged inside each slot 13. A fixed plate 16 is fixedly connected to the bottom surface of each impact rod 14. An impact ball 15 is fixedly connected to the bottom surface of each fixed plate 16.

[0033] The positions of several fixed balls 12 and several impact balls 15 are on the same circumference.

[0034] Each fixed plate 16 is fixedly connected to the top wall of the support frame 3 by a set of elastic steel plates 17.

[0035] After the impact rod 14 is installed, there is a certain gap between it and the upper surface of the support frame 3.

[0036] When the bottom surface of the molding cavity 5 is pressed close to the upper surface of the support frame 3, the power switch connected to the drive motor 10 is turned on, causing the output shaft of the drive motor 10 to rotate. At this time, the fixed disk 11, which is fixedly connected to the output shaft of the drive motor 10, will rotate synchronously. At this time, the fixed ball 12 will collide with the impact ball 15. Since both the fixed ball 12 and the impact ball 15 are circular, when the fixed ball 12 collides with the impact ball 15, the impact ball 15 will cause the fixed plate 16 and the impact rod 14 to rise. At this time, the top surface of the impact rod 14 will impact the bottom surface of the molding cavity 5. As the fixed disk 11 continues to rotate, it will continuously impact the bottom surface of the molding cavity 5.

[0037] By setting up the vibration component 2, when the impact rod 14 vibrates and impacts the bottom surface of the molding cavity 5, the material inside the molding cavity 5 can be pressed more compactly, and the problem of material crushing due to the accumulation of alumina hollow spheres can be avoided, which would affect the quality of the finished product.
