Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ceramic tile production technology, specifically relating to a split upper mold for ceramic tile production. Background Technology
[0002] Tile production molds refer to the mold tools used to manufacture tiles. Molds play a crucial role in tile production, determining the shape and size of the tiles. Tiles are typically formed from powder. By using separate upper and lower molds, the powder is pressed to form ceramic tile blanks, which are then subjected to processes such as sintering to form ceramic tiles.
[0003] Patent CN219171211U discloses "a grooved tile production mold, relating to the field of tile production molds, including a middle frame, alloy side plates, a bottom plate, a push plate, an electromagnetic base, a lower mold, an upper mold, an upper magnetic plate, and a hydraulic support. The inner wall of the middle frame is fitted with alloy side plates. After the mold is opened, the ejector pin extends, and the tip of the ejector pin protrudes from the connecting groove and enters the interior of the vent hole, preventing blockage inside the vent hole and making the vent hole of the grooved tile production mold less prone to blockage."
[0004] Although the existing technology can be used to press ceramic tiles, some powder will enter the vent holes of the upper mold during the pressing process. Under the push of the ejector pin, the powder in the vent holes will be pushed deeper into the vent holes and compacted, which increases the difficulty of clearing the vent holes later. Therefore, it needs to be improved. Utility Model Content
[0005] The purpose of this utility model is to provide a split upper mold for ceramic tile production in order to solve the above-mentioned problems.
[0006] This utility model achieves the above objectives through the following technical solutions:
[0007] A split upper mold for tile production includes an upper mold body, an exhaust mechanism opened in the upper mold body, and a sealing mechanism provided in the exhaust mechanism. The top of the upper mold body is detachably equipped with an installation plate. The exhaust mechanism includes a wide hole opened in the upper mold body, a narrow hole opened at the bottom of the upper mold body and communicating with the wide hole, and an air outlet opened on one side of the upper mold body and communicating with the wide hole.
[0008] A filter plate is fixedly installed at the bottom of the narrow hole of the upper mold body. The filter plate has several filter holes. The sealing mechanism includes an elastic piston at the bottom of the mounting plate and several rods at the bottom of the elastic piston that are inserted into the filter holes.
[0009] As a further optimization of this utility model, the top of the upper mold body is provided with an installation groove communicating with the wide hole, and the installation plate can be detachably installed in the matching installation groove.
[0010] As a further optimization of this utility model, the elastic piston component includes a spring fixedly disposed at the bottom of the mounting plate and a piston plate fixedly disposed at the bottom end of the spring. The piston plate is movably disposed in a matching narrow hole, and a plurality of the insert rods are fixedly connected to the bottom of the piston plate.
[0011] As a further optimization of this utility model, a telescopic rod is fixedly installed between the bottom of the mounting plate and the top of the piston plate.
[0012] As a further optimization of this utility model, two sets of rotating frames are fixedly provided inside the air outlet of the upper mold body, and a rotating rod coaxial with the air outlet is rotatably provided between the two sets of rotating frames.
[0013] As a further optimization of this utility model, one end of the rotating rod extends to the outside of the upper mold body, and a scraper that abuts against the inner wall of the air outlet is fixed on the outer wall of the rotating rod.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. The exhaust mechanism can quickly expel air from the mold when the upper mold body is closed with the lower mold, which speeds up the pressing process and improves production efficiency. Furthermore, the filter holes in the filter plate prevent powder from easily entering the exhaust mechanism during venting. After venting, the elastic piston will block the filter plate, allowing the powder to remain at the bottom of the upper mold body during the pressing process, thus improving the pressing effect.
[0016] 2. By closing the upper mold body with the lower mold, the piston plate inside the elastic piston component moves upward under the push of gas, thus not obstructing the exhaust mechanism. After exhaust, the piston plate will return to its original position under the spring force, and the insert rod will be inserted back into the filter hole to unclog the filter hole. This is convenient and practical. Rotating the rotating rod will drive the scraper to rotate and scrape off foreign objects attached to the vent hole. The scraped foreign objects can be blown out of the vent hole under the blowing of the subsequent mold closing, thereby reducing the difficulty and intensity of cleaning the vent hole.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0024] Example
[0025] like Figure 1-5 As shown, a split upper mold for ceramic tile production includes an upper mold body 1, an exhaust mechanism, and a sealing mechanism. The upper mold body 1 is the upper mold used for ceramic tile production, which can press and shape the powder in the lower mold to produce ceramic tile blanks.
[0026] like Figure 1-3 As shown, the upper mold body 1 is detachably equipped with an mounting plate 3 on its top. The exhaust mechanism includes a wide hole 12 opened in the upper mold body 1, a narrow hole 13 opened at the bottom of the upper mold body 1 and communicating with the wide hole 12, and an exhaust hole 14 opened on one side of the upper mold body 1 and communicating with the wide hole 12. The wide hole 12 can connect the exhaust hole 14 and the narrow hole 13.
[0027] When the upper mold body 1 closes with the lower mold, the air inside the mold is compressed and discharged into the outside air through the narrow hole 13, wide hole 12 and air outlet 14 in the exhaust mechanism, thereby quickly expelling the air inside the mold, accelerating the pressing process and improving production efficiency.
[0028] like Figure 1-3 As shown, the top of the upper mold body 1 is provided with an installation groove 11 that communicates with the wide hole 12. The mounting plate 3 can be detachably installed in the matching mounting groove 11. The mounting plate 3 can be installed in the mounting groove 11 of the upper mold body 1 by means of detachable screws or other means. The operator can remove the mounting plate 3 to clean the exhaust mechanism.
[0029] like Figure 2-4 As shown, a filter plate 2 is fixedly installed at the bottom of the narrow hole 13 of the upper mold body 1. The filter plate 2 has several filter holes 21. When venting, the powder in the mold can be blocked by the filter holes 21 in the filter plate 2, so that the powder is not easy to enter the venting mechanism when venting, reducing the difficulty of cleaning the venting mechanism by the staff later.
[0030] like Figure 2-4 As shown, the sealing mechanism is located within the exhaust mechanism. The sealing mechanism includes an elastic piston at the bottom of the mounting plate 3 and several rods 34 at the bottom of the elastic piston and inserted into the filter hole 21. The elastic piston includes a spring 32 fixedly located at the bottom of the mounting plate 3 and a piston plate 33 fixedly located at the bottom of the spring 32. The piston plate 33 is movably located within a matching narrow hole 13. Several rods 34 are fixedly connected to the bottom of the piston plate 33. The piston plate 33 abuts against the top of the filter plate 2. The piston plate 33 can connect the spring 32 and the rods 34.
[0031] When the upper mold body 1 closes with the lower mold, it will compress the air inside the mold, thereby increasing the air pressure inside the mold. At this time, the air inside the mold will push the insert rod 34 upward through the filter hole 21, thereby causing the piston plate 33 at the top of the insert rod 34 to move upward and disengage from the narrow hole 13. The air inside the mold will then enter the wide hole 12 through the filter hole 21 and the narrow hole 13, and be discharged into the outside air through the air outlet 14, so that the piston plate 33 will not obstruct the exhaust during mold closing.
[0032] After the air inside the mold is expelled, the piston plate 33 will spring back to its original position under the elastic force of the spring 32, thereby inserting the insert rod 34 back into the filter hole 21. This can both clear and block the filter hole 21, so that the powder can be left at the bottom of the upper mold body 1 during the pressing process, and it is not easy to leave powder columns or other marks on the ceramic brick blank formed after pressing, thereby improving the pressing effect.
[0033] like Figure 1-3 As shown, a telescopic rod 31 is fixedly installed between the bottom of the mounting plate 3 and the top of the piston plate 33. The telescopic rod 31 can be an existing square telescopic rod. The telescopic rod 31 can limit the piston plate 33 and other components, so that the piston plate 33 and other components can only move up and down.
[0034] like Figure 1 , Figure 2 and Figure 5As shown, two sets of rotating frames 4 are fixedly installed inside the air outlet 14 of the upper mold body 1. A rotating rod 41 coaxial with the air outlet 14 is rotatably installed between the two sets of rotating frames 4. One end of the rotating rod 41 extends to the outside of the upper mold body 1. A scraper 42 that abuts against the inner wall of the air outlet 14 is fixedly installed on the outer wall of the rotating rod 41. The rotating frame 4 is hollow inside and can support and limit the rotation of the rotating rod 41.
[0035] Rotating the rotating rod 41 will drive the scraper 42 to rotate. The rotated scraper 42 can scrape away the foreign objects attached to the air outlet 14. The scraped foreign objects can be blown out of the air outlet 14 under the blowing air during the subsequent mold closing, thereby reducing the difficulty and intensity of subsequent cleaning of the air outlet 14.
[0036] It should be noted that, in the use of this type of split upper mold for tile production, the powder is first added into the lower mold, and then the split upper mold body 1 is pressed into the lower mold by external hydraulic press or other equipment to close the mold.
[0037] When the upper mold body 1 closes with the lower mold, it will compress the air inside the mold, thereby increasing the air pressure inside the mold. At this time, the air inside the mold will push the insert rod 34 upward through the filter hole 21, thereby causing the piston plate 33 at the top of the insert rod 34 to move upward and disengage from the narrow hole 13. The air inside the mold will then enter the wide hole 12 through the filter hole 21 and the narrow hole 13, and be discharged into the outside air through the air outlet 14, thus quickly expelling the air inside the mold, accelerating the pressing process, and improving production efficiency.
[0038] When the air inside the mold is expelled, the piston plate 33 will spring back to its original position under the elastic force of the spring 32, thereby inserting the rod 34 back into the filter hole 21. This can both clear and block the filter hole 21, allowing the powder to remain at the bottom of the upper mold body 1 during the pressing process, thus improving the pressing effect.
[0039] Furthermore, rotating the rotating rod 41 will drive the scraper 42 to rotate. The rotated scraper 42 can scrape away the foreign objects attached to the air outlet 14. The scraped foreign objects can be blown out of the air outlet 14 under the blowing air during the subsequent mold closing, thereby reducing the difficulty and intensity of cleaning the air outlet 14.
[0040] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
