Description

Technical Field

[0001] This utility model relates to the field of ceramic tile molds, specifically a layering and pressing device for ceramic tile molds. Background Technology

[0002] Tile molds are specialized tools used for the mass production of tiles, typically precision-machined from high-hardness steel. Their internal cavities, with specific patterns or textures, compress ceramic powder under high pressure into blanks of a fixed shape and size. The design of the mold directly determines the surface pattern, dimensional accuracy, and edge details of the tile.

[0003] Chinese patent discloses a new type of ceramic tile mold (authorization announcement number CN219132665U). The patented technology includes two sets of pressing molds. One set of pressing molds is provided with a base pattern template. The base pattern template includes a base plate. The base plate is provided with embossed patterns. The two sets of embossed patterns are distributed in an alternating manner. The embossed patterns include several parallel raised patterns. The spacing between several adjacent raised patterns is not equal. The center of the base plate is arc-shaped protrusion.

[0004] However, existing technologies have the following problems when used:

[0005] Firstly, in the preparation of layered ceramic tiles, the existing technology is cumbersome and inefficient in the layered pressing operation. It lacks a convenient step-by-step pressing and material conveying structure. When adding multiple layers of materials, the mold position needs to be adjusted manually frequently, which can easily lead to material spillage. It is impossible to efficiently achieve step-by-step molding of different materials, which affects the molding efficiency and structural consistency of layered ceramic tiles.

[0006] Secondly, existing technologies are prone to quality problems due to residual gas in the mold groove during pressing, and have low energy efficiency. Air bubbles generated by the mixing of air or materials in the mold groove cannot be effectively discharged, and the tiles are prone to hollowing and uneven surfaces after pressing. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a layered pressing device for ceramic tile molds. This device solves the technical problems of the current layered pressing process being discontinuous, cumbersome, and difficult to efficiently press multiple layers of materials step by step. At the same time, residual gas in the mold groove is prone to generating air bubbles, resulting in poor ceramic tile pressing quality.

[0008] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a layered pressing device for a ceramic tile mold is designed, including a workbench, a support is installed on the upper end of the workbench, a hydraulic cylinder is installed on the upper end of the support, a telescopic rod is installed on the lower end of the hydraulic cylinder, an upper mold is installed on the lower end of the telescopic rod, a lower mold is placed on the upper end of the workbench and the lower mold is connected to the upper mold, a first connecting pipe is installed above the end of the lower mold, a feed hopper is installed on the upper end of the first connecting pipe, a first flexible hose is connected to the end of the first connecting pipe, a pump body is installed at the lower end of the first flexible hose, and a second flexible hose is connected to the front end of the pump body;

[0009] The lower mold cavity is equipped with a venting plate, and a second connecting pipe is installed below the end of the lower mold. The end of the second connecting pipe is connected to a third flexible hose, and the end of the third flexible hose is connected to the pump body.

[0010] In this design, a workbench serves as the basic support platform, with a hydraulic cylinder fixed to its upper bracket. Upon activation of the hydraulic cylinder, a telescopic rod moves the upper mold up and down, aligning it with the lower mold on the workbench to press the first material into shape. After the first layer of pressing is completed, the upper mold moves upward, introducing the second material into the feed hopper. The pump is then activated, supplying air through a first hose to a first connecting pipe, assisting the material in entering the mold cavity of the lower mold. Simultaneously, a venting disc within the lower mold cavity engages with a second connecting pipe, allowing the pump to extract gas from the mold cavity through a third hose, preventing air bubbles during pressing. The extracted gas can also flow back to the first connecting pipe to assist in material feeding, balancing molding quality and energy efficiency.

[0011] Preferably, the lower end of the workbench is fixed with four support columns arranged in a rectangular array, and each of the four support columns has a support plate installed at its lower end.

[0012] In practical applications, the four support columns at the bottom of the worktable are arranged in a rectangular array, and each support column is equipped with a support plate at its bottom, which greatly improves the overall stability and safety of the device. The four support columns can evenly distribute the weight of the worktable, the upper support, the hydraulic cylinder, and the upper and lower molds, avoiding excessive local stress that could cause the device to tilt. The support plate increases the contact area with the placement surface, reduces the unit pressure, and ensures that the device is level even on uneven surfaces, laying the foundation for the docking of the upper and lower molds.

[0013] Preferably, the upper end of the bracket has a through hole, and the bottom end of the telescopic rod of the hydraulic cylinder passes through the through hole.

[0014] In practical applications, a through hole is provided at the upper end of the bracket, through which the bottom end of the hydraulic cylinder's telescopic rod passes, providing guidance for the movement of the telescopic rod and ensuring the stability of the upper mold's trajectory. The through hole is adapted to the shape of the telescopic rod, limiting its lateral offset or swaying. The lower end of the telescopic rod is directly connected to the upper mold, and its guidance directly determines the alignment accuracy between the upper and lower molds. Whether it's the mating of the first layer of material or the resetting of the second layer, misalignment problems caused by upper mold offset can be avoided.

[0015] Preferably, a third connecting pipe is installed at the upper end of the first connecting pipe, and the first connecting pipe is connected to the third connecting pipe. The upper end of the third connecting pipe is connected to the lower end of the feed hopper. A material trough is opened at the upper end of the feed hopper, and the material trough is connected to the third connecting pipe.

[0016] In practical applications, a third connecting pipe is installed at the upper end of the first connecting pipe and connected to it. The upper end of the third connecting pipe is connected to the feed hopper, and a material trough connected to the third connecting pipe is opened at the upper end of the feed hopper, optimizing the feeding path of the second material. The third connecting pipe avoids the problem of mismatched diameters or dead angles when the feed hopper is directly connected to the first connecting pipe, ensuring smooth material flow. The material trough provides convenient operating space for adding materials, reducing spillage and waste, and preventing material accumulation and blockage. When the pump delivers air to the first connecting pipe, the third connecting pipe allows the gas to mix better with the material, pushing the material evenly into the mold cavity, ensuring a consistent thickness of the second layer of material, and facilitating layered pressing.

[0017] Preferably, a first valve is installed at the upper end of the first connecting pipe, and a third valve is installed at the side end of the third connecting pipe.

[0018] In practical applications, a first valve is installed at the upper end of the first connecting pipe, and a third valve is installed at the side end of the third connecting pipe. These valves provide control over the feeding and gas-assisted processes, improving the controllability of the layered pressing process. The first valve controls the opening and closing of the first connecting pipe channel and the flow rate. Opening the valve during feeding ensures the flow of gas and material, and adjusting the opening degree controls the delivery rate, preventing problems caused by excessive material or excessive gas flow. The third valve specifically controls the feeding from the feed hopper to the first connecting pipe. Closing the valve when adding material prevents premature feeding and blockage, while opening it during feeding coordinates with the gas to achieve orderly feeding. Closing it after feeding prevents backflow of gas and material. The two valves work together to adjust the feeding timing and speed, ensuring the delivery of the second layer of material and reducing product defects.

[0019] Preferably, the lower mold has a mold groove at its upper end, and a circular groove is formed at the lower side of the inner wall of the mold groove. The venting plate is installed on the inner wall of the circular groove. The venting plate is made of porous ceramic material with uniformly distributed micropores inside.

[0020] In practical applications, the upper end of the lower mold has a groove to serve as the tile forming space. A circular groove is cut into the lower side of the inner wall of the groove, and a venting plate is installed within this groove. The venting plate is made of porous ceramic material with uniform micropores, ensuring proper venting of the mold groove and preventing material leakage. The circular groove provides positioning and stable support for the venting plate, preventing it from shifting during pumping. The pores of the porous ceramic allow gas to pass through while preventing tile material leakage, avoiding pipe blockage or material waste. When the pump is pumping air, the gas in the mold groove passes through the venting plate into the second connecting pipe and is discharged, effectively eliminating compressed air bubbles and improving the density and smoothness of the tile structure.

[0021] Preferably, the second connecting pipe is connected to the circular groove, and the second connecting pipe is coaxial with the horizontal axis of the vent plate, and a second valve is installed at the upper end of the second connecting pipe.

[0022] In practical applications, the second connecting pipe is connected to the circular groove and is collinear with the horizontal axis. A second valve is installed at the upper end of the second connecting pipe, optimizing exhaust efficiency and controllability of the extraction process. The collinearity reduces gas flow resistance within the second connecting pipe, preventing airflow stagnation and ensuring rapid and complete gas removal from the mold cavity, further reducing the risk of air bubbles in the ceramic tile. The second valve controls the on / off state of the second connecting pipe and the gas flow rate. Closing the valve when not extracting gas prevents external air from entering the mold cavity; adjusting the valve opening during extraction controls the extraction speed, preventing material displacement and deformation due to pressure differences.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. When preparing the layered ceramic tile mold according to this utility model, the first type of ceramic tile material is first placed into the mold groove of the lower mold. The lower mold is placed stably on the upper part of the worktable. The hydraulic cylinder on the support is started, and the telescopic rod at its lower end will drive the upper mold to move downward until the upper mold and the lower mold are connected, thus completing the pressing and forming of the first type of material. Then, the hydraulic cylinder is started again, and the telescopic rod drives the upper mold to move upward to a suitable position. Subsequently, the second type of material is introduced into the feed hopper at the upper end of the first connecting pipe. After the pump body is started, it will introduce gas into the first connecting pipe through the first hose. The second type of material enters the mold groove along with the gas. Finally, the upper mold is driven to move downward again to connect and press with the lower mold, which facilitates the layered pressing of the ceramic tile.

[0025] 2. In the process of introducing the second material, the pump body is activated and gas is introduced into the first connecting pipe through the second hose, blowing the material into the mold cavity. At the same time, the pump body also plays a suction role through the third hose. Under the suction force, the gas in the mold cavity will pass through the vent plate in the lower mold cavity and enter the second connecting pipe, and finally be extracted by the pump body. This can effectively remove the gas in the mold cavity, avoid the generation of air bubbles during pressing, and greatly improve the pressing quality. At the same time, the extracted gas is not wasted, but is transported back to the first connecting pipe by the pump body to provide auxiliary thrust for the delivery of the second material, thus taking into account both processing efficiency and energy utilization.

[0042] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0043] Example 1: A layering and pressing device for a ceramic tile mold, see [link / reference] Figures 1 to 5 The system includes a workbench 110, a support 120 mounted on the upper end of the workbench 110, a hydraulic cylinder 140 mounted on the upper end of the support 120, a telescopic rod 130 mounted on the lower end of the hydraulic cylinder 140, an upper mold 200 mounted on the lower end of the telescopic rod 130, a lower mold 210 placed on the upper end of the workbench 110 and connected to the upper mold 200, a first connecting pipe 220 mounted above the end of the lower mold 210, a feed hopper 310 mounted on the upper end of the first connecting pipe 220, a first flexible hose 300 connected to the end of the first connecting pipe 220, a pump body 320 mounted on the lower end of the first flexible hose 300, and a second flexible hose 330 connected to the front end of the pump body 320. The lower end of the platform 110 is fixed with four support columns 100 arranged in a rectangular array, and support plates are respectively installed at the lower ends of the four support columns 100; the upper end of the bracket 120 is provided with a through hole, and the bottom end of the telescopic rod 130 of the hydraulic cylinder 140 passes through the through hole; the upper end of the first connecting pipe 220 is provided with a third connecting pipe 350, and the first connecting pipe 220 and the third connecting pipe 350 are connected; the upper end of the third connecting pipe 350 is connected to the lower end of the feed hopper 310; the upper end of the feed hopper 310 is provided with a material trough 311, and the material trough 311 is connected to the third connecting pipe 350; the upper end of the first connecting pipe 220 is provided with a first valve, and the side end of the third connecting pipe 350 is provided with a third valve;

[0044] In the preparation of layered ceramic tile molds, when layered ceramic tile pressing is required, the operator first uses the workbench 110 as a stable support base and smoothly places the first type of ceramic tile material into the mold groove 211 opened at the upper end of the lower mold 210. At this time, the lower mold 210 is placed on the upper end of the workbench 110, providing a fixed forming space for subsequent pressing. Then, the hydraulic cylinder 140 installed on the upper end of the bracket 120 is activated. The hydraulic cylinder 140 acts as a power source to drive the lower telescopic rod 130 to extend and retract downwards. The upper mold 200 connected to the lower end of the telescopic rod 130 moves downwards synchronously with the movement of the telescopic rod 130 until the upper mold 200 and the lower mold 210 are aligned. During the alignment process, the stable support of the bracket 120 for the hydraulic cylinder 140 and the directional extension and retraction of the telescopic rod 130 together ensure the alignment of the upper mold 200 and the lower mold 210, ensuring that the first type of material can be evenly pressed in the mold groove 211, thereby completing the initial pressing and forming of the first layer of material.

[0045] After the first layer of material is formed, the hydraulic cylinder 140 is activated again, causing the telescopic rod 130 to move the upper mold 200 upward to a suitable height. At this time, an open space is formed at the upper end of the mold groove 211, facilitating the addition of the second layer of material. The operator can introduce the second type of ceramic tile material into the feed hopper 310 installed at the upper end of the first connecting pipe 220 above the lower mold 210. Then, the pump body 320 is activated, and gas is introduced into the first connecting pipe 220 through the first hose 300 connected to the front end. At the same time, the second type of material in the feed hopper 310 enters the first connecting pipe 220 under the combined action of its own gravity and the thrust of the gas, and mixes with the introduced gas to form a stable conveying flow, which finally flows smoothly into the mold groove 211 and is evenly laid on top of the first layer of material. After the second type of material is laid, the hydraulic cylinder 140 drives the telescopic rod 130 again to move the upper mold 200 downward, docking with the lower mold 210 again and applying pressure to complete the overall pressing of the two layers of material. The entire process, through the phased docking of the upper mold 200 and the lower mold 210 and the step-by-step addition of materials, achieves the layered pressing of the tiles. The operation process is smooth and controllable, effectively meeting the molding requirements of layered tiles.

[0046] For details, see Figures 1 to 5 The lower mold 210 has a vent plate 240 installed in its inner cavity. A second connecting pipe 230 is installed below the end of the lower mold 210. A third hose 340 is connected to the end of the second connecting pipe 230 and the end of the third hose 340 is connected to the pump body 320. A mold groove 211 is opened at the upper end of the lower mold 210. A circular groove 212 is opened below the inner side of the mold groove 211. The vent plate 240 is installed on the inner wall of the circular groove 212. The vent plate 240 is made of porous ceramic material and has uniformly distributed micropores inside. The second connecting pipe 230 communicates with the circular groove 212 and is coaxial with the horizontal axis of the vent plate 240. A second valve is installed at the upper end of the second connecting pipe 230.

[0047] Meanwhile, during the introduction and pressing of the second material, when the second material is introduced into the mold groove 211, the pump body 320, after starting, not only delivers auxiliary feeding gas to the first connecting pipe 220 through the first hose 300, but also plays a suction role through the third hose 340 connected to the second connecting pipe 230 below the end of the lower mold 210. Air that may remain in the mold groove 211 or air bubbles generated by the material flow will enter the second connecting pipe 230 through the vent plate 240 installed in the inner cavity of the lower mold 210 under the suction force of the pump body 320. The structure of the vent plate 240 can both allow the gas to pass smoothly and prevent the ceramic material from leaking, ensuring that the material will not enter the pipe and cause blockage during the suction process.

[0048] The extracted gas, after entering the pump body 320 through the second connecting pipe 230 and the third flexible hose 340, is not directly discharged and wasted. Instead, it is pumped back into the first connecting pipe 220 by the pump body 320, where it merges with the existing auxiliary gas to jointly propel the second material into the mold trough 211. On the one hand, by timely discharging the gas from the mold trough 211, air bubbles formed due to gas residue during the pressing of the second material are completely avoided, significantly improving the compactness and surface flatness of the layered tiles and ensuring product quality. On the other hand, the gas is recycled, reducing energy consumption. At the same time, the recycled gas enhances the pushing force on the second material, making the material more evenly laid in the mold trough 211, further improving the stability of the layered structure and enhancing the efficiency and quality assurance of the device.

[0049] It should be noted that the hydraulic cylinder 140 and pump body 320 mentioned in the text are both existing technologies. The hydraulic cylinder 140 is a HOB heavy-duty tie rod hydraulic cylinder 140. Its principle is based on Pascal's law. By injecting hydraulic oil into the inner cavity of the cylinder, the pressure generated by the hydraulic oil pushes the piston to move along the cylinder axis, thereby driving the extension rod 130 to extend and retract, realizing the lifting and pressing action of the upper mold 200, which meets the stable thrust and displacement control required for the pressing of layered ceramic tiles. The pump body 320 is a YB1 series vane pump. Its principle is that the rotor is driven to rotate by the motor. The vanes on the rotor are pressed tightly against the pump under the action of centrifugal force, forming a periodically changing sealed volume. When the volume increases, it generates suction to draw gas, and when the volume decreases, it generates pressure to push gas. It can not only extract gas from the mold groove 211, but also deliver gas to the first connecting pipe 220 to assist in feeding, adapting to the gas circulation and material conveying needs of the device.

[0050] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0051] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
