Description

Technical Field

[0001] This utility model belongs to the field of casting technology, specifically relating to a casting device for precast refractory materials. Background Technology

[0002] Precast refractory components refer to precast components made of materials that can maintain stable performance in high-temperature environments. These materials can withstand extremely high temperatures without melting or softening and are commonly used as linings for high-temperature kilns, smelting furnaces, and other high-temperature equipment. They come in a variety of materials, including high-alumina, silica, and clay, with the appropriate material selected based on the specific application.

[0003] Currently, the production process of precast refractory products mainly includes raw material processing, batching and mixing, casting, curing and demolding, and drying and baking. In the casting process, the mixed materials from the previous step are poured into a suitable mold, and then vibration is used to remove air bubbles and improve density, thus forming the product. However, existing molds and vibration tables cannot be quickly fixed and disassembled before and after casting, making them inflexible and inconvenient to use. Furthermore, most conventional vibration tables only use mechanical vibration, which has limited effect on air bubble removal and density improvement, resulting in low overall casting quality that needs improvement. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a precast casting device for refractory material products, which can realize convenient disassembly and assembly of molds and dual vibration molding, so as to solve the above problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a precast casting device for refractory materials, comprising a base and a mold, wherein guide supports are provided at the four corners of the top of the base, and the top of each guide support is connected to a common vibration table, a vibrator is installed at the bottom of the vibration table, and a positioning groove is fixedly provided at the top, an ultrasonic oscillator is installed on the outer side of the positioning groove, and vertical plates are fixedly provided on the vibration table on the left and right sides of the positioning groove, a lead screw is rotatably provided on the side of the vertical plate away from the positioning groove, and a rotating handle is fixedly connected to the end of the lead screw away from the vertical plate. A movable plate is threaded onto the rod. Guide plates are fixedly connected to both ends of the movable plate. The guide plates face the vertical plate and have guide grooves that pass through them. The guide plates pass through the corresponding guide grooves and have limit plates fixedly connected to their ends. A pin is fixedly installed on the side of the limit plate near the positioning groove. The lower part of the mold is inserted into the positioning groove. U-shaped handles are fixedly installed on both the left and right outer sides of the mold. Blind holes are opened on both ends of the handles away from the mold. The limit plate abuts against the handles on the same side. The pins correspond one-to-one with the blind holes on the same side and are inserted into them.

[0006] Preferably, the guide support consists of a telescopic rod and a spring sleeved on the outside of the telescopic rod, with the bottom end of the telescopic rod and the top end of the spring fixedly connected to the base and the top end fixedly connected to the vibration table.

[0007] Preferably, the lower part of the mold is adapted to the positioning groove.

[0008] Preferably, the guide plate is adapted to the corresponding guide groove.

[0009] Preferably, the insert shaft is adapted to the corresponding blind hole.

[0010] Preferably, the base is made of aluminum foam.

[0011] The beneficial effects of this utility model are as follows: During the casting molding process, the material is first poured into the corresponding mold. Then, the entire mold is transferred and placed into the positioning groove of the vibrating table using the handle. Next, the screw is rotated by the handle. With the threaded connection between the moving plate and the screw, and the insertion and guidance of the guide plate and the guide groove, the moving plate and guide plate move towards the handle until the limiting plate presses against the corresponding handle. At this point, the insert shaft can be inserted into the corresponding blind hole, thus locking the handle in place and completing the mold fixation. Then, the vibrator and ultrasonic oscillator are run. The vibrator generates vibration force acting on the vibrating table, which, in conjunction with the guide support, applies mechanical vibration to the mold. The ultrasonic oscillator generates ultrasonic waves to apply ultrasonic vibration to the mold, thereby more quickly and comprehensively eliminating air bubbles in the material, making the material denser. After molding, the vibrator and ultrasonic oscillator are turned off. Then, the screw is reversed by the handle, causing the insert shaft to exit the corresponding blind hole, thus releasing the handle's insertion lock. Finally, the mold is removed from the positioning groove and sent for curing and demolding. This allows for flexible and quick assembly and disassembly of the mold before and after molding, making operation simple, more flexible and convenient to use, and improving efficiency. At the same time, it enables dual mechanical and ultrasonic vibration of the mold during molding, resulting in more efficient and comprehensive bubble removal and more effective improvement in density, thus making the overall casting quality higher and more practical.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 6 As shown, a precast casting device for refractory products includes a base 1 and a mold 2. Guide supports 3 are provided at the four corners of the top of the base 1, and a vibration table 4 is connected to the top of each guide support 3. A vibrator 5 is installed at the bottom of the vibration table 4, and a positioning groove 6 is fixedly provided at the top. An ultrasonic oscillator 7 is installed on the outer side of the positioning groove 6. Vertical plates 8 are fixedly provided on the vibration table 4 on both sides of the positioning groove 6. A lead screw 9 is rotatably provided on the side of the vertical plate 8 away from the positioning groove 6. A handle 10 is fixedly connected to the end of the lead screw 9 away from the vertical plate 8. A movable plate 11 is threaded onto the lead screw 9. Guide plates 12 are fixedly connected to both the front and rear ends of the movable plate 11. A guide groove 13 is provided through the corresponding vertical plate 8 facing the guide plate 8. A limiting plate 14 is fixedly connected to the end of the guide plate 12 through the corresponding guide groove 13. A shaft 15 is fixedly provided on the side of the limiting plate 14 near the positioning groove 6. The lower part of the mold 2 is inserted into the positioning groove 6. U-shaped handles 16 are fixed on both the left and right outer sides of the mold 2. Blind holes 17 are opened on both the front and rear ends of the handle 16 away from the mold 2. The limiting plate 14 abuts against the handle 16 on the same side. The insertion shaft 15 corresponds to the blind hole 17 on the same side and is inserted. During the casting process, the material is first poured into the corresponding mold 2. Then, the entire mold 2 is transferred and placed into the positioning groove 6 of the vibrating table 4 using the handle. Next, the screw 9 is rotated by the handle 10. With the threaded connection between the moving plate 11 and the screw 9, and the insertion and guidance of the guide plate 12 and the guide groove 13, the moving plate 11 and the guide plate 12 move towards the handle 16 until the limiting plate 14 presses against the corresponding handle 16. At this time, the insertion shaft 15 can be inserted into the corresponding blind hole 17, thereby pressing and locking the handle 16, completing the fixation of the mold 2. Then, the vibrator 5 and the ultrasonic oscillator 7 are run. The vibrator 5 generates vibration force acting on the vibrating table 4, which, together with the guide support 3, applies mechanical vibration to the mold 2. The ultrasonic oscillator 7 generates ultrasonic waves to apply ultrasonic vibration to the mold 2, thereby more quickly and thoroughly eliminating air bubbles in the material and making the material more compact. After molding, turn off vibrator 5 and ultrasonic oscillator 7, then reverse screw 9 via handle 10 to drive insert shaft 15 out of corresponding blind hole 17, thus releasing the locking of handle 16. Then, remove mold 2 from positioning groove 6 and send it for curing and demolding. This allows for flexible and quick assembly and disassembly of mold 2 before and after molding, simplifying operation, increasing efficiency, and enabling both mechanical and ultrasonic vibration of mold 2 during molding. This results in more efficient and comprehensive air bubble removal, more effective densification, higher overall casting quality, and greater practicality.

[0015] In this embodiment, the guide support 3 consists of a telescopic rod 18 and a spring 19 sleeved on the outside of the telescopic rod 18. The bottom ends of the telescopic rod 18 and the spring 19 are fixedly connected to the base 1, and the top ends are fixedly connected to the vibration table 4. This allows for effective support of the vibration table 4 while ensuring a certain degree of freedom for the vibration table 4, facilitating vibration of the vibration table under the drive of the vibrator 5, and enabling vibration molding processing. Both the telescopic rod 18 and the spring 19 can be made using existing technology. Specifically, the telescopic rod 18 is a rod that slides and fits into a sleeve, allowing it to extend and retract under the elastic force of the spring 18.

[0016] In this embodiment, the lower part of the mold 2 is adapted to the positioning groove 6 to ensure that the mold 2 is placed smoothly in place.

[0017] In this embodiment, the guide plate 12 is adapted to the corresponding guide groove 13 to ensure the smooth movement of the moving plate and the guide plate as a whole.

[0018] In this embodiment, the insert shaft 15 is adapted to the corresponding blind hole 17 to ensure that the insert shaft 15 is smoothly inserted into the corresponding blind hole, thereby achieving the insertion and locking of the handle 16.

[0019] In this embodiment, the base 1 is made of aluminum foam, which is an existing material with high damping, shock absorption and energy absorption properties. It can reduce the adverse effects of vibration on the external environment when the vibration table 4 is working, making it more practical.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
