[0002] Shelf plates, also known as kiln plates or silicon carbide heat-resistant plates, are an indispensable component in the ceramic production process. They are used to support and separate ceramic products and are plate-shaped. This plate can not only bear the weight of ceramic products, but also maintain a stable and strong structure in an extremely high temperature environment, thereby ensuring that the ceramic products are not deformed or damaged during the firing process.

[0003] The shape of the shelf is mainly thin sheets, with a large surface area and relatively thin thickness. It is directly exposed to the scorching flames during the firing process.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figure 1-Figure 2 As shown, a shelf plate for ceramic production is provided. Compared with the solid shelf plate structure, the shelf plate increases its heat dissipation area by designing heat dissipation through holes 101, so that the heat accumulated inside can be quickly dissipated under the high temperature of ceramic firing. In addition, by optimizing the internal structure of the heat dissipation through holes 101 and providing conical heat dissipation through holes 101, the heat dissipation effect is further improved, and the processed shelf plate is easy to demould.

[0036] Furthermore, in this embodiment, the shelf structure is as follows: Figure 1 and Figure 2As shown, it includes a shelf body 100 and a heat dissipation through hole 101, wherein the shelf body 100 is a rectangular parallelepiped structure, which is convenient for stable production, and is more convenient and cost-saving in the design of the corresponding molding mold. In other embodiments, it can also be other different three-dimensional structures, which are determined according to actual needs; at the same time, the above-mentioned heat dissipation through holes 101 are arranged in multiple groups along the width direction of the shelf body 100, and the distance between each heat dissipation through hole 101 needs to meet the design requirements, and the heat dissipation through hole 101 is parallel to the length direction of the shelf body 100. The heat dissipation through hole 101 is located at the midline position in the thickness direction of the shelf body 100, and the distance to the upper and lower surfaces of the shelf body 100 is consistent, so as to maintain the consistency of the upper and lower strengths and improve the overall structural strength. In addition, the heat dissipation through hole 101 is divided into left and right parts, which expand outward from the middle to form two symmetrical groups of trumpet structures. Since the heat inside the shelf body 100 needs a long stroke in the horizontal direction to diffuse outward, and the trumpet structure facilitates the rapid outward diffusion of the heat inside the shelf body 100, the heating temperature of the entire shelf body 100 is more uniform.

[0037] It should be noted that the outward diffusion angles of the two ends of the above-mentioned heat dissipation holes 101 need to be strictly set according to the design angle to avoid affecting the strength of the shelf body 100. At the same time, in other embodiments, the heat dissipation holes 101 can also be arranged to form a stepped diffusion area with multiple groups of conical surfaces. The inclination angle of the outer conical surface is greater than the inclination angle of the inner conical surface, which further increases the heat dissipation area and gradually expands the heat dissipation cavity, thereby weakening the mutual influence of heat diffusion at different positions.

[0038] Example 2

[0039] The present embodiment is an extrusion molding device for processing the shelf in Embodiment 1. Since the shelf body 100 in Embodiment 1 of the present invention has trumpet-shaped heat dissipation holes 101 at both ends, and the heat dissipation holes 101 are located in the middle of the thickness direction of the shelf body 100, conventional extrusion molding devices usually adopt an up and down extrusion molding method, and the position of the heat dissipation holes 101 cannot be accurately guaranteed. In addition, the mold that forms the heat dissipation holes 101 during molding will cause certain molding interference to the up and down movement of the raw materials, affecting the finished product quality of the above-mentioned shelf.

[0040] Based on this, this embodiment designs an extrusion molding device, which is applied to the molding process of the shelf in the above embodiment 1, wherein Figure 3As shown, the above-mentioned extrusion molding device includes a molding base 1 installed on the production line, an extrusion mechanism 2, a molding mechanism 3 and a discharge mechanism 4, wherein the extrusion mechanism 2 is arranged on the top of the molding base 1, and is used for preliminary extrusion in the up and down directions to limit the thickness size. A molding mechanism 3 is also arranged on the top surface of the molding base 1. The molding mechanism 3 corresponds to the extrusion mechanism 2 up and down, and is the basic structure for realizing molding. A discharge mechanism 4 is arranged on the discharge side of the molding base 1, which is used to discharge the molded shelf.

[0041] The thickness direction is initially limited by the extrusion mechanism 2 and the molding mechanism 3, and then the extrusion molding is performed by the structures on the left and right sides of the molding mechanism 3, so as to ensure that the heat dissipation through hole 101 is stably formed in the middle of the thickness direction of the shelf body 100. At the same time, the raw material can move unobstructed in the horizontal direction of the molding, and the molding is more dense, thereby improving the quality of the finished product of the shelf.

[0042] like Figure 1 As shown, the above-mentioned forming base 1 includes a support frame 11 at the bottom, and the support frame 11 can be fixed on the production line by welding or bolting. In other embodiments, the bottom of the support frame 11 can also be installed with a walking wheel with a self-braking function to facilitate the turnover movement of the entire device. A processing substrate 12 is installed on the top of the support frame 11, and the two sides of the processing substrate 12 are divided into a feeding side and a discharging side (wherein Figure 3 The front side is the discharging side, and the rear side is the feeding side), wherein a rectangular movable square groove 14 with an open end is provided in the middle of the processing substrate 12, and the opening of the movable square groove 14 faces the discharging side, and a material guiding substrate 13 is also provided at one end of the discharging side of the processing substrate 12. The material guiding substrate 13 is inclined downward and is used to guide the formed shelf plate into the corresponding collection device. In order to guide the material more stably, a baffle 15 is also provided on the processing substrate 12 on the side of the material guiding substrate 13 to prevent the unloading mechanism 4 from tilting when pushing the material, resulting in unsmooth material guiding.

[0043] Further, the unloading mechanism 4 is arranged corresponding to the material guiding base plate 13 and is flush in the unloading direction, and the forming mechanism 3 is slidably arranged in the movable square groove 14 to adjust the unloading position of the formed shelf.

[0044] The specific structure of the extrusion mechanism 2 is as follows: Figure 3As shown, guide columns 21 are arranged at the four corners of the top of the processing substrate 12, a top plate 22 is installed on the top of the four guide columns 21, a hydraulic cylinder 23 is installed at the center of the top surface of the top plate 22, and the four guide columns 21 are slidably connected with a moving substrate 24, which is located below the top plate 22 and is connected to the telescopic rod of the hydraulic cylinder 23. The moving substrate 24 can be driven to move up and down by the hydraulic cylinder 23, and is guided by the four guide columns 21 to ensure the stability of the movement of the moving substrate 24, wherein an upper pressing plate 25 is fixedly connected to the position corresponding to the forming mechanism 3 at the center of the bottom surface of the moving substrate 24, and cooperates with the forming mechanism 3 to achieve thickness limitation for the shelf processing when it moves down to the set position.

[0045] Further Figure 4-Figure 7 As shown, the above-mentioned forming mechanism 3 includes a slide plate 39 slidably arranged in the movable square groove 14, and a lower pressing template 33 is installed on the top of the slide plate 39. The position of the lower pressing template 33 corresponds to the upper pressing template 25, and they can cooperate with each other after the upper pressing template 25 moves down. A connecting seat 38 is arranged at the bottom of the slide plate 39, and a moving cylinder 37 is installed at the bottom feeding side end of the processing substrate 12. The telescopic rod of the moving cylinder 37 is connected to the connecting seat 38 by a pin. The lower pressing template 33 is pushed by the moving cylinder 37 to move in the movable square groove 14, so that the lower pressing template 33 is moved to correspond to the unloading mechanism 4 to realize unloading.

[0046] Further Figure 4 and Figure 5 As shown, a semi-I-shaped forming cavity 331 is provided inside the lower pressing template 33, and the left and right ends of the forming cavity 331 in the length direction are through-set, and side pressing templates 35 are symmetrically and slidably provided on the left and right sides of the forming cavity 331, and the outer section of the side pressing template 35 is connected to a movable base 34, and a mounting groove is provided at the outer end of the movable base 34, and a matching block 36 is installed in the mounting groove. Further, fixed bases 31 are symmetrically provided at corresponding positions on both sides of the processing substrate 12, and multiple groups of forming cylinders 32 are parallelly provided on the outer side surface of the fixed base 31, and the telescopic rods of the forming cylinders 32 on the same side penetrate the fixed base 31 and are connected to the matching blocks 36 on the same side, so as to achieve the purpose of pushing the side pressing template 35 to move by the forming cylinder 32, and then the synchronous movement of the side pressing templates 35 on both sides extrude the raw materials inside the forming cavity 331 after limiting the thickness.

[0047] Further Figure 6 and Figure 7As shown, a plurality of groups of molding rods 310 are arranged inside the side pressing template 35, and the plurality of groups of molding rods 310 are arranged horizontally at equal intervals, and the plurality of groups of molding rods 310 on both sides are matched one by one, wherein a boss is arranged at the end of the molding rod 310 on one side, and a groove is arranged at the end of the molding rod 310 on the other side to achieve docking. When forming, the thickness dimension is limited by the upper pressing template 25 and the lower pressing template 33, wherein the thickness dimension is manually set, and the position where the molding rod 310 is installed on the side pressing template 35 is located in the middle of the upper pressing template 25 and the lower pressing template 33. During the lateral extrusion forming process, the molding rod 310 remains unchanged in the middle, and the heat dissipation through hole 101 is accurately processed.

[0048] The installation of the forming rod 310 is as follows: Figure 6 and Fig. 9 As shown, multiple groups of telescopic cylinders 341 are installed in the mobile base 34, and the axes of the multiple groups of telescopic cylinders 341 are all flush with the center of the thickness of the shelf board, wherein the forming rods 310 on the same side are inserted into the corresponding telescopic cylinders 341, and are slidably connected with the inner wall of the telescopic cylinder 341, and further, a matching cavity 361 is opened at the position of the matching block 36 corresponding to the telescopic cylinder 341, and the matching cavity 361 is adapted to the shaft diameter of the tail end of the forming rod 310, so that the tail end of the forming rod 310 can slide in the matching cavity 361, and the matching cavity 361 is connected with the inner cavity of the telescopic cylinder 341, so as to facilitate the telescopic movement of the forming rod 310 during the forming process.

[0049] Further Fig. 9 and Fig.10 As shown, the above-mentioned forming rod 310 includes a tapered portion 311 and a straight tube portion 312, wherein the tapered portion 311 is located at the front end forming position, and the straight tube portion 312 is located at the rear end cooperating with other structures, and a clamping table 313 is also arranged on the straight tube portion 312. The forming rod 310 is slidably arranged in the telescopic cylinder 341 through the clamping table 313, and a telescopic spring 342 is sleeved between the clamping table 313 and the matching block 36 for realizing the reset of the forming rod 310. The forming rods 310 on both sides can be docked before the forming extrusion, and then the side pressure template 35 is driven to perform extrusion forming.

[0050] It should be noted that, in other embodiments, the tapered portion 311 of the forming rod 310 may also be divided into a plurality of cone combinations to match the corresponding heat dissipation through hole 101 structure.

[0051] Further Figure 2 and Figure 8As shown, the above-mentioned unloading mechanism 4 includes a mounting platform 41 arranged on the discharge side of the processing substrate 12, and a pushing cylinder 43 is installed on the outer side of the mounting platform 41, and the telescopic rod of the pushing cylinder 43 passes through the mounting platform 41 and is connected to a pushing plate 42. When the lower pressing template 33 carrying the formed shelf plate moves to the set unloading position, the pushing plate 42 is driven by the pushing cylinder 43 to move, and the shelf plate is pushed out of the forming cavity 331, and then slides from the material guiding substrate 13 to the collecting device.

[0052] The method of using the extrusion molding device of the present invention is:

[0053] Preparation stage: Start the moving cylinder 37 to drive the lower pressure plate 33 to move to the corresponding position above and below the upper pressure plate 25, and then start the molding cylinder 32 to push the moving base 34 to move, so that the side pressure plates 35 on both sides slide into the molding cavity 331, and the multiple groups of molding rods 310 on both sides cooperate and engage with each other. It should be noted that at this time, the telescopic spring 342 is in an initial compression state, providing the molding rod 310 with a preliminary horizontal extrusion force, and the distance between the end faces of the side pressure plates 35 on both sides is greater than the actual length of the shelf produced.

[0054] Extrusion molding stage: the raw material is injected into the molding cavity 331 from the feeding side through the external quantitative feeding device, and then the hydraulic cylinder 23 is started to push the moving base plate 24 to move downward, and the moving base plate 24 drives the upper pressing plate 25 to move to the set position, and the thickness direction of the shelf plate processing is preliminarily limited. Then, the molding cylinders 32 on both sides are started synchronously to push the moving base 34 to move, and the moving base 34 drives the side pressing plate 35 to move further, so as to realize the synchronous extrusion on both sides, so that the raw material is formed between the upper pressing plate 25, the lower pressing plate 33 and the side pressing plates 35 on both sides to obtain a formed shelf plate. During the synchronous extrusion, since the molding rod 310 cannot move due to the mutual resistance, the tail of the molding rod 310 begins to squeeze the telescopic spring 342 and inserts it into the matching cavity 361, so that when the moving base 34 and the side pressing plate 35 move, the molding rod 310 remains stationary, thereby avoiding affecting the molding of the heat dissipation through hole 101.

[0055] Demolding stage: After molding, the molding cylinders 32 on both sides are started to drive the moving base 34 to move, and the moving base 34 drives the side pressure plate 35 to move until the molding rod 310 is separated from the molding shelf. Since the molding rod 310 is provided with a conical surface in the molding area, demoulding is easier. After the molding rods 310 on both sides are separated from the molding cavity 331, the hydraulic cylinder 23 is started to drive the upper pressure plate 25 to rise and reset. After that, the moving cylinder 37 is started to push the lower pressure plate 33 to the unloading side, so that the push plate 42 corresponds to the lower pressure plate 33, and the push cylinder 43 is started to drive the push plate 42 to move, so that the molding shelf in the molding cavity 331 is pushed out, slides off the material guide base plate 13, and is collected.
