A gasket structure for ceramic molding

Abstract

This utility model discloses a gasket structure for ceramic molding, which is fixedly installed with a die head and located on the side of a back roller. It includes a ceramic flow channel, with side flanges on both sides of the flow channel. The ends of the ceramic flow channel and the side flanges have protrusions facing the back roller, causing the ends of the ceramic flow channel to protrude beyond the side end plane of the die head. Thus, by providing protrusions at the ends of the ceramic flow channel and the side flanges facing the back roller, the ceramic flow channel protrudes under the guidance of the die head, bringing the ceramic material closer to the back roller, reducing the thickness of the formed ceramic layer, and significantly shortening the drying time, greatly improving drying efficiency and reducing production energy consumption. The protrusions also form a physical isolation barrier, effectively preventing the mutual solubility of the ceramic and the material area, reducing the mutual solubility rate, ensuring clear edges of the finished product, and improving the product's appearance quality.

Description

Technical Field

[0001] This utility model relates to the field of ceramic forming equipment technology, and in particular to a gasket structure for ceramic forming. Background Technology

[0002] In the ceramic forming process, a spacer is required. The ceramic flow channel structure of the spacer plays a key role in the quality and production efficiency of ceramic products. The die head includes an upper die head and a lower die head. The spacer is fixed between the upper die head and the lower die head. In the existing technology, the ceramic flow channel of the traditional spacer has the following defects: (1) The end of the ceramic flow channel of the traditional spacer is flush with the side end of the die head, and the back roller is set on the side of the die head, which results in an excessively large distance between the back roller and the ceramic flow channel, making the formed ceramic too thick, increasing the drying difficulty and time cost; (2) The ceramic and the material area are prone to mutual dissolution during the processing, which makes the edge of the finished product blurry and seriously affects the appearance and precision of the product.

[0003] Therefore, there is an urgent need for a gasket structure that can solve the above problems. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a gasket structure for ceramic molding.

[0005] This utility model proposes a gasket structure for ceramic molding, which is fixedly installed with a die head and located on the side of a back roller. It includes a ceramic flow channel, and both sides of the ceramic flow channel are provided with baffles. The ends of the ceramic flow channel and the baffles are provided with protrusions facing the back roller. The protrusions cause the ends of the ceramic flow channel to protrude from the side end plane of the die head.

[0006] This allows the ceramic material to be closer to the back roller, reducing the thickness of the ceramic layer and significantly shortening the drying time, thereby greatly improving drying efficiency and reducing production energy consumption. The raised part forms a physical isolation barrier, effectively avoiding the problem of mutual solubility between the ceramic and the material area, reducing the mutual solubility rate, ensuring clear edges of the finished product, and improving the appearance quality of the product.

[0007] Preferably, the extension length of the protrusion is set to 0.1 mm.

[0008] Thus, the design of the protrusion brings the ceramic material closer to the back roller during the molding process, reducing the contact time and area between the ceramic and the material zone, thereby effectively preventing mutual solubility between the two. Furthermore, although the 0.1mm protrusion is small in size, it acts as a reinforcing rib in the ceramic flow channel structure, increasing the local rigidity of the ceramic flow channel.

[0009] Preferably, the gap between the ceramic flow channel and the back roller is reduced by 0.1 mm.

[0010] This brings the ceramic material closer to the back roller 1, enhancing the fit between the back roller 1 and the ceramic flow channel 2, creating conditions for forming a thinner ceramic layer, and reducing the thickness of the formed ceramic layer.

[0011] Preferably, the width of the ceramic flow channel is set to 5±0.5mm, and its inner wall is provided with a mirror polished layer.

[0012] Thus, a reasonable flow channel width ensures the smooth flow and shaping of ceramic materials.

[0013] Preferably, a dual-blade spacing adjustment system is also provided, which is used to adjust the ceramic blade spacing and the material zone blade spacing to achieve a misalignment compensation of 0.1 mm.

[0014] Thus, the 0.1mm misalignment adjustment of the back compensation gap restores the tool distance to the set value, ensuring forming accuracy.

[0015] Preferably, the ceramic flow channel and the baffle are an integral structure, and the height of the baffle is greater than that of the ceramic flow channel.

[0016] This simplifies the manufacturing process and ensures the structural stability of the irregularly shaped gasket.

[0017] Preferably, the ceramic flow channel and the baffle are made of stainless steel, with an operating temperature range of 150-300℃, a compressive strength ≥450MPa, and a surface roughness Ra≤0.05μm.

[0018] Thus, stainless steel possesses excellent strength, corrosion resistance, and stability, making it suitable for ceramic molding and processing environments. Within this temperature range, the irregularly shaped gasket structure can operate stably, ensuring smooth ceramic processing. With a pressure resistance of ≥450MPa, it ensures that the gasket will not deform or be damaged when subjected to processing pressure. The surface roughness Ra≤0.05μm, with its smooth surface, facilitates the flow and molding of ceramic materials and reduces material adhesion problems.

[0019] In summary, this utility model has the following beneficial effects: by providing protrusions at the ends of the ceramic flow channel and the sidewalls towards the back roller, the ceramic flow channel protrudes under the guidance of the die head, making the ceramic material closer to the back roller, reducing the thickness of the formed ceramic layer, and correspondingly shortening the drying time, greatly improving drying efficiency and reducing production energy consumption; the protrusions form a physical isolation barrier, effectively avoiding the problem of mutual solubility between the ceramic and the material area, reducing the mutual solubility rate, ensuring clear edges of the finished product, and improving the product appearance quality.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] like Figure 1-2 As shown, this embodiment proposes a gasket structure for ceramic molding, which is fixedly installed with a die head (the die head includes an upper die head and a lower die head, and the gasket is fixed between the upper die head and the lower die head) and located on the side of the back roller 1. It includes a ceramic flow channel 2, and both sides of the ceramic flow channel 2 are provided with a retaining edge 3. The ends of the ceramic flow channel 2 and the retaining edge 3 are provided with a protrusion 4 facing the back roller 1. The protrusion 4 makes the end of the ceramic flow channel 2 protrude out of the end plane of the die head side.

[0027] Specifically, the ceramic flow channel 2 and the retaining edge 3 are designed as an integral structure, and the height of the retaining edge 3 is greater than that of the ceramic flow channel 2. Furthermore, the ceramic flow channel 2 and the retaining edge 3 are made of stainless steel, which has good strength, corrosion resistance, and stability, and can adapt to the ceramic forming and processing environment; the working temperature range is 150-300℃, within which the irregularly shaped gasket structure can operate stably, ensuring smooth ceramic processing; the pressure resistance is ≥450MPa, ensuring that the gasket will not deform or be damaged when subjected to processing pressure; the surface roughness Ra≤0.05μm, the smooth surface facilitates the flow and forming of ceramic materials, reducing material adhesion problems.

[0028] Thus, by providing protrusions 4 at the ends of the ceramic flow channel 2 and the baffle 3 towards the back roller 1, the ceramic flow channel 2 protrudes under the guidance of the die head, making the ceramic material closer to the back roller 1, reducing the thickness of the formed ceramic layer, and correspondingly shortening the drying time, greatly improving drying efficiency and reducing production energy consumption; the protrusions 4 form a physical isolation barrier, effectively avoiding the problem of mutual solubility between ceramic and material area, reducing the mutual solubility rate, ensuring clear edges of finished products, and improving the appearance quality of products.

[0029] Furthermore, the extension length of the protrusion 4 is set to 0.1 mm. The gap between the ceramic flow channel 2 and the back roller 1 is reduced by 0.1 mm. The design of the protrusion allows the ceramic material to be closer to the back roller during the molding process, reducing the contact time and contact area between the ceramic and the material zone, thereby effectively avoiding the mutual dissolution phenomenon between the two. Although the 0.1 mm protrusion is small in size, it acts as a reinforcing rib in the ceramic flow channel structure, increasing the local rigidity of the ceramic flow channel.

[0030] This brings the ceramic material closer to the back roller 1, enhancing the fit between the back roller 1 and the ceramic flow channel 2, creating conditions for forming a thinner ceramic layer, and reducing the thickness of the formed ceramic layer.

[0031] Furthermore, the width of the ceramic flow channel 2 is set at 5±0.5mm, and its inner wall is provided with a mirror-polished layer. The reasonable flow channel width ensures the smooth flow and forming of the ceramic material.

[0032] In this embodiment, a dual-blade spacing adjustment system is also provided, which is used to adjust the ceramic blade spacing and the material zone blade spacing to achieve a misalignment compensation of 0.1mm.

[0033] It should be noted that the specific structure of the dual tool spacing adjustment system in this embodiment includes two sets of tool holders, an adjustment drive mechanism, a compensation device, and a positioning component.

[0034] The system includes two sets of tool holders: a main tool holder and a secondary tool holder, each equipped with a cutting tool. The two sets are arranged in parallel with an adjustable spacing. The main tool holder is used to complete the main cutting and shaping work of the ceramic flow channel 2, while the secondary tool holder assists in the finishing and dimensional calibration. The two work together to ensure the accuracy of the flow channel processing.

[0035] Adjustment drive mechanism: Composed of a motor, transmission gear set, and lead screw and nut pair. The motor serves as the power source, transmitting power to the lead screw and nut pair via the transmission gear set, thereby driving the tool holder to move linearly along the guide rail, achieving precise adjustment of the tool distance. A servo motor can be used, paired with a high-precision encoder, to provide real-time feedback on the tool holder's position, ensuring adjustment accuracy.

[0036] Compensation device: Includes a compensation block, an elastic element, and a displacement sensor. The compensation block is mounted on the secondary tool post and can move slightly under the action of the elastic element; the displacement sensor monitors the relative position of the main and secondary tool posts in real time, and when it detects a tool pitch deviation caused by factors such as wear and thermal deformation, it promptly feeds back a signal to the control system.

[0037] Positioning assembly: Consists of a positioning pin, a positioning slot, and a limit switch. The positioning pin works with the positioning slot to accurately position the tool holder at its initial position; the limit switch restricts the movement range of the tool holder to prevent damage to the equipment due to over-adjustment.

[0038] Thus, before starting the equipment, the initial distance between the main and auxiliary tool holders is set by the control system according to the processing requirements of the ceramic product. This distance corresponds to the 5mm width required for the ceramic flow channel 2. At this time, the adjustment drive mechanism drives the main and auxiliary tool holders to move to the corresponding positions, and the positioning component ensures that the tool holders are accurately positioned. During ceramic processing, the displacement sensor continuously monitors the relative positions of the main and auxiliary tool holders. When a deviation in the tool distance is detected, the control system calculates the compensation amount based on the deviation data and sends a command to the adjustment drive mechanism. The adjustment drive mechanism drives the compensation block on the auxiliary tool holder to move slightly under the action of the elastic element, realizing a 0.1mm misalignment adjustment of the rear compensation gap, restoring the tool distance to the set value, and ensuring the processing accuracy of the ceramic flow channel 2. After the ceramic processing is completed, the adjustment drive mechanism drives the main and auxiliary tool holders to reset to the initial position, waiting for the next processing task.

[0039] The dual tool spacing adjustment system operates on the basis of precise position monitoring and dynamic compensation mechanisms. During the machining of ceramic runner 2, factors such as tool wear, equipment vibration, and changes in ambient temperature may cause the actual distance between the main and auxiliary tool holders to deviate from the initial set value, thus affecting the forming accuracy of ceramic runner 2. Displacement sensors monitor the relative positions of the main and auxiliary tool holders in real time. Once a tool spacing deviation is detected, a signal is transmitted to the control system. The control system calculates the required adjustment amount based on a preset algorithm and compensation strategy and sends a command to the adjustment drive mechanism. The adjustment drive mechanism, through the coordinated operation of a motor, transmission gear set, and lead screw and nut pair, drives the compensation block on the auxiliary tool holder to move, achieving a 0.1mm misalignment compensation and restoring the distance between the main and auxiliary tool holders to the ideal state. This post-compensation mechanism can correct tool spacing deviations in a timely manner without affecting machining continuity, ensuring that ceramic runner 2 always maintains high-precision machining dimensions and effectively improving the forming quality and processing stability of ceramic products.
