Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, specifically to a high-alumina ceramic protective tube preform forming mold. Background Technology

[0002] As we all know, common ceramic materials include clay, alumina, kaolin, etc. Ceramic materials generally have high hardness and are widely used in daily life. Ceramic round tubes are commonly used in daily life. In the production of ceramic round tubes, they need to be shaped.

[0003] The existing production methods for high-alumina ceramic protective tubes generally include stamping and molding. Stamping sometimes produces burrs, and during molding, due to the adhesive properties of high-alumina ceramics, it may stick to the mold. In this case, workers need to manually remove it from the mold using hand tools. However, the temperature of the protective tube is relatively high immediately after molding, which may cause injury to the workers. Utility Model Content

Detailed Implementation

[0028] 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.

[0029] See Figures 1-5 A high-alumina ceramic protective tube blank forming mold includes a base plate 1, a lower mold 2, an upper mold 3, a demolding component 4, a limiting component 8, and a material conveying port 9.

[0030] The lower mold 2 is fixed on top of the base plate 1, which provides a stable support foundation for the entire mold, ensuring that the mold will not shift or shake during the molding process. The lower mold 2 is the main load-bearing part for the preform molding, and its shape and size determine the bottom shape and size of the preform. The stable connection between the lower mold 2 and the base plate 1 ensures the stability of the entire molding process. The upper mold 3 is installed on top of the lower mold 2. The upper mold 3 and the lower mold 2 cooperate to form the molding space of the high-alumina ceramic protective tube preform. The shape and size of the upper mold 3 correspond to those of the lower mold 2. The two cooperate to form the injected raw material within a specific space, ensuring the overall shape of the preform. The placement groove 5 is opened on top of the lower mold 2, and at least one end of the first spring 6 is fixed in the placement groove 5. A pressure plate 7 is slidably installed within the placement groove 5. The bottom of the pressure plate 7 is fixed to the other end of the first spring 6. After the blank is formed, the upper mold 3 is removed, and the elastic force of the first spring 6 pushes the pressure plate 7 upward. The pressure plate 7 lifts the formed blank from the mold groove of the lower mold 2, facilitating demolding, greatly improving demolding efficiency, and reducing the possibility of damage to the blank during demolding. Vertical plates 10 are fixed to the top two sides of the pressure plate 7. Two sliding grooves 11 are opened on the lower mold 2, and sliding plates 12 are slidably installed within the sliding grooves 11. One end of the sliding plate 12 is fixed to the vertical plate 10, and the top of the sliding plate 12 is in contact with the upper mold 3. During the demolding process of the pressure plate 7 rising, the vertical plate 10 drives the sliding plate 12 to slide upward within the sliding grooves 11. The sliding plate 12 acts as a guide. To ensure the stability of the pressure plate 7 during its ascent, the top of the sliding plate 12 is in contact with the upper mold 3, providing support and preventing the upper mold 3 from shifting due to uneven force during demolding. A groove 13 is formed on the top of the lower mold 2, and a slider 14 is slidably mounted within it. A pull rod 15 is fixed to the top of the slider 14, located at the top of the mold groove of the lower mold 2. A drive assembly 16 is mounted on the side of the lower mold 2. A slide rail 29 adapted to the pull rod 15 is formed on the upper mold 3. The drive assembly 16 can drive the slider 14 to slide within the groove 13, thereby moving the pull rod 15. During mold closing, the pull rod 15 can move along the slide rail 29 of the upper mold 3, further limiting and guiding the position of the upper mold 3. The upper mold 3 is used to ensure accurate installation on the lower mold 2, guaranteeing mold closing accuracy. During demolding, the pull rod 15 assists in pulling the blank out of the mold groove, enhancing the demolding effect. The limiting component 8 is installed on both sides of the upper mold 3, which restricts the position of the upper mold 3 during installation and use, preventing the upper mold 3 from shifting left or right, and ensuring precise alignment of the upper mold 3 and the lower mold 2 during mold closing, thereby guaranteeing the dimensional accuracy and quality stability of the molded blank. The feeding port 9 is located at the top of the upper mold 3. During the molding process, the high-alumina ceramic raw material is injected into the molding space formed by the upper and lower molds 2 through the feeding port 9. Through the close cooperation of the base 1, lower mold 2, upper mold 3, demolding component 4, limiting component 8, and feeding port 9, etc.,This high-alumina ceramic protective tube preform forming mold can efficiently and accurately form high-alumina ceramic protective tube preforms, meeting production requirements.

[0031] First, refer to Figure 4 In this embodiment, the drive assembly 16 is mainly used to control the slider 14 to move within the groove 13, thereby driving the pull rod 15 to operate. The screw 17 is rotatably disposed within the groove 13 and is threadedly connected to the slider 14. When the screw 17 rotates, based on the thread transmission principle, the slider 14 will slide along the axial direction of the screw 17 within the groove 13. One end of the screw 17 passes through the lower mold 2, and a pulley 18 is fixed at this end. An installation groove 19 is opened on the side of the lower mold 2, and a motor 20 is fixed in the installation groove 19. The output shaft of the motor 20 is connected to the pulley 18 through a transmission belt 21. After the motor 20 starts, the output shaft drives the transmission belt 21 to rotate, and the transmission belt 21 drives the pulley 18 to rotate. The pulley 18 drives the screw 17 to rotate, ultimately realizing the movement of the slider 14. This driving method can control the displacement of the slider 14, ensuring that the pull rod 15 plays a stable limiting, guiding, and auxiliary demolding role during mold closing and demolding, greatly improving the controllability of mold operation and the stability of molding process.

[0032] Then, refer to Figure 5 In this embodiment, the limiting component 8 is installed on both sides of the upper mold 3, playing a key role in ensuring the mold closing accuracy of the upper and lower molds 2. It includes a rotating rod 22, which is rotatably mounted on both sides of the upper mold 3 via a thread. A limiting plate 23 is rotatably mounted on the rotating rod 22, with one side of the limiting plate 23 fitting against the upper mold 3. Limiting blocks 24 are fixedly mounted on both sides of the lower mold 2. A limiting groove 25 adapted to the limiting block 24 is opened on the limiting plate 23, and the limiting groove 25 fits against the limiting block 24. When installing the upper mold 3, the position of the limiting plate 23 can be adjusted by rotating the rotating rod 22 via the thread, so that the limiting groove 25 on the limiting plate 23 is accurately aligned with and fits against the limiting block 24 of the lower mold 2. This design effectively prevents the upper mold 3 from shifting left or right during installation and use, ensuring precise alignment when the upper and lower molds 2 are closed, thereby ensuring the dimensional accuracy and quality stability of the molded blank, and avoiding dimensional deviations or defects in the blank due to mold misalignment.

[0033] Finally, see Figure 4In this embodiment, a first support seat 26 is fixedly installed on one side of the lower mold 2, and a second support seat 27 is rotatably installed on the other side. A round rod 28 is fixed to the top of the first support seat 26. The round rod 28 provides the necessary conditions for die-casting hollow pipes. When the raw material is injected into the molding space formed by the upper and lower molds 2, the raw material around the round rod 28 will eventually form the shape of a hollow pipe. The design of the second support seat 27 being rotatably installed is mainly to cooperate with the pull rod 15 and the pipe removal operation. When the pull rod 15 drives the die-cast pipe to move under the action of the drive component 16, the pipe will push open the rotatable second support seat 27, so that the pipe can be smoothly removed from the mold. The whole process ensures the stability of the mold structure and also facilitates the efficient demolding and product removal process.

[0034] Working principle:

[0035] When using this high-alumina ceramic protective tube preform forming mold, first check whether all parts of the mold are intact, ensuring that the demolding component 4, the limiting component 8, etc. are working properly. Rotate the rotating rods 22 on both sides of the upper mold 3 to adjust the position of the limiting plate 23, so that the limiting groove 25 on the limiting plate 23 is aligned with the limiting blocks 24 on both sides of the lower mold 2 and fits together, ensuring that the upper and lower molds 2 are accurately aligned when closing. Start the motor 20 in the drive component 16. The output shaft of the motor 20 drives the transmission belt 21 to rotate, and the transmission belt 21 drives the pulley 18 to rotate, which in turn causes the screw 17 to rotate. The screw 17 drives the slider 14 to slide in the slide groove 13 through the threaded transmission. The pull rod 15 at the top of the slider 14 moves accordingly. The pull rod 15 moves along the slide 29 of the upper mold 3, which plays a limiting and guiding role for the upper mold 3, assisting the upper mold 3 to be accurately installed on the lower mold 2, completing the mold closing operation. The top feed port 9 injects high-alumina ceramic raw material into the molding space formed by the upper and lower molds 2. The raw material is distributed around the round rod 28 at the top of the first support seat 26 to prepare for die casting of the hollow ceramic protective tube. After the blank is formed, the drive assembly 16 is activated again to move the pull rod 15 to the appropriate position to assist in demolding. At the same time, due to the elastic force of the first spring 6, the pressure plate 7 in the placement groove 5 moves upward to push the formed high-alumina ceramic protective tube out of the mold groove of the lower mold 2. During the upward movement of the pressure plate 7, the vertical plate 10 drives the sliding plate 12 to slide upward in the sliding groove 11 to ensure that the pressure plate 7 rises smoothly. The top of the sliding plate 12 provides a certain support for the upper mold 3. As the pressure plate 7 and the pull rod 15 push the blank out, the blank pushes away the rotatable second support seat 27. The operator removes the formed high-alumina ceramic protective tube blank from the mold, completing one molding operation.
