Description

Technical Field

[0001] This utility model relates to the field of ceramic forming technology, specifically to a vacuum casting molding equipment for wear-resistant ceramic liners. Background Technology

[0002] A utility model patent with patent number CN202223218242.7 describes a "vacuum forming equipment for silicon carbide composite ceramics," comprising a mixing tank, a casting tank, and a casting mold. The mixing tank has an internal stirring device, a drain hole at its bottom, and a vacuum equipment connection hole on its side wall. The casting tank has an inlet hole and a vacuum equipment connection hole on its side wall. The casting mold is installed inside the casting tank. The drain hole at the bottom of the mixing tank connects to the beginning of a delivery pipeline, and the end of the delivery pipeline passes through the side wall of the casting tank and connects to the injection port of the casting mold. Both the vacuum equipment connection holes of the mixing tank and the casting tank are connected to a vacuum pump via pipelines. A delivery pump is installed on the delivery pipeline, and valves are respectively installed at the drain hole of the mixing tank and the outlet of the delivery pump. The ceramic products produced by this utility model's forming equipment have a dense internal structure without pores, resulting in improved wear resistance.

[0003] However, in the above-mentioned utility model, since the injection position is on one side of the mold, the casting liquid will accumulate on one side when entering the casting mold. Therefore, the casting liquid entering the casting mold cannot be quickly and evenly distributed in the casting mold, which will reduce the molding efficiency of the ceramic liner.

[0004] Therefore, a vacuum casting molding equipment for wear-resistant ceramic liners is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a vacuum casting molding equipment for wear-resistant ceramic liners. This equipment can rapidly distribute the injected casting liquid by horizontally shaking the casting mold, thereby improving the molding efficiency of ceramic liners.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vacuum casting molding equipment for wear-resistant ceramic liners, comprising a mixing tank, a casting pipe connected to the bottom of the mixing tank, a casting tank connected to the left end of the casting pipe, a vacuum pump installed at the outer ends of both the mixing tank and the casting tank, two mutually symmetrical guide rails fixedly connected between the left and right inner walls of the casting tank, a casting mold provided at the upper end of the guide rails, and two mutually symmetrical sliders fixedly connected to the bottom end of the casting molds, the sliders being located at the outer ends of the guide rails and slidingly connected to the guide rails. Next, a through hole is drilled at the left end of the casting tank, and an insert rod is inserted into the through hole. A pressing bladder is fixedly connected to the right end of the insert rod. The pressing bladder is located on the left side of the casting mold and is in contact with the casting mold. A pressing plate is fixedly connected to the left end of the insert rod. A spring is fixedly connected to the left inner wall of the casting tank. A contact plate that contacts the casting mold is fixedly connected to the outer end of the spring. This allows the casting liquid injected into the casting mold to be quickly distributed by shaking the casting mold in the horizontal direction, thereby improving the molding efficiency of the ceramic liner.

[0007] Preferably, a valve is installed at the outer end of the pouring pipe. The valve is located at the inlet of the pouring pipe near the mixing tank. By setting the valve, the release of the pouring liquid in the mixing tank can be controlled.

[0008] Preferably, an anti-slip sleeve is fixedly connected to the outer end of the pouring pipe. The anti-slip sleeve is located at the opening of the pouring pipe inside the pouring mold. By setting the anti-slip sleeve, when the pouring mold moves horizontally, the anti-slip sleeve can buffer the pouring pipe so that the inner wall of the pouring mold is not easily damaged when it comes into contact with the pouring pipe.

[0009] Preferably, a distance sensor is installed on the inner wall of the casting tank. By setting the distance sensor, the distance between the liquid surface of the casting liquid can be detected when the casting mold moves, so as to confirm whether the casting liquid in the casting mold has been evenly distributed.

[0010] Preferably, a polished layer is provided at the contact points between the guide rail and the slider. By providing the polished layer, the slider can slide more smoothly on the guide rail.

[0011] Preferably, a limiting ring is fixedly connected to the outer end of the insertion rod. The limiting ring is located between the pressing bladder and the casting tank. By setting the limiting ring, the pressing bladder is less likely to come into contact with the inner wall of the casting tank, thereby making the connection between the pressing bladder and the casting tank less likely to be damaged.

[0012] Preferably, the surface of the pressing plate is engraved with anti-slip texture. By setting anti-slip texture on the surface of the pressing plate, it is not easy for technicians to slip when pressing the pressing plate, thereby improving the work efficiency of technicians.

[0013] Compared with the prior art, this utility model provides a vacuum casting molding equipment for wear-resistant ceramic liners, which has the following beneficial effects: 1. This equipment uses the combination of a pressing plate, insert rod, pressing bladder, spring and contact plate to realize the periodic left and right shaking of the casting mold. This horizontal shaking allows the injected casting liquid to be distributed quickly and evenly, effectively avoiding local accumulation or uneven distribution, reducing molding time, improving production efficiency, and ensuring that the density and performance of each part of the ceramic liner are consistent, thus improving the stability of product quality.

[0014] 2. The guide rail and slider of this equipment are equipped with a polished layer to reduce sliding friction, reduce wear, and extend their service life; the anti-slip sleeve plays a buffering role when the casting mold moves and contacts the casting pipe to prevent damage to the pipe; the limit ring prevents the pressing bladder from contacting the inner wall of the casting tank, protects the connection, reduces equipment failure, and lowers maintenance costs and downtime.

[0015] 3. The pressing plate of this equipment is engraved with anti-slip texture, which makes it less likely for technicians to slip when pressing, making operation more convenient and improving work efficiency; the valve can precisely control the release of the casting liquid in the mixing tank to meet different production needs; the distance sensor can detect the distance of the casting liquid surface in real time to confirm whether it is evenly distributed, providing technicians with accurate data to facilitate timely adjustments to the operation.

[0018] 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. Example:

[0019] Please see Figure 1 - Figure 5 The wear-resistant ceramic liner vacuum casting molding equipment in this embodiment includes a mixing tank 1, a casting pipe 2 connected to the bottom of the mixing tank 1, and a casting tank 3 connected to the left end of the casting pipe 2. Vacuum pumps 13 are installed at the outer ends of both the mixing tank 1 and the casting tank 3. Two symmetrical guide rails 4 are fixedly connected between the left and right inner walls of the casting tank 3. The cross-section of the guide rails 4 is I-shaped, which prevents the sliders 6 from easily separating from the guide rails 4. A casting mold 5 is provided at the upper end of the guide rails 4. Two symmetrical sliders 6 are fixedly connected to the bottom end of the casting mold 5. The sliders 6 are slidably connected to the guide rails 4. A through hole 7 is drilled at the left end of the casting tank 3, and a rod 8 is inserted into the through hole 7. The contact point between the through hole 7 and the rod 8 is sealed. A pressing bladder 9 is fixedly connected to the right end of the rod 8. The pressing bladder 9 is located on the left side of the casting mold 5 and is in contact with the casting mold 5. A pressing plate 10 is fixedly connected to the left end of the rod 8. A spring 11 is fixedly connected to the left inner wall of the casting tank 3. A contact plate 12 that is in contact with the casting mold 5 is fixedly connected to the outer end of the spring 11. This allows the casting liquid injected into the casting mold to be quickly distributed by moving the casting mold horizontally, thereby improving the molding efficiency of the ceramic liner.

[0020] When the insert rod 8 moves in the through hole 7, it will drive the pressing bladder 9 to apply force to the casting mold 5. The left end of the insert rod 8 is fixedly connected to the pressing plate 10. By pressing the pressing plate 10, the technician can push the insert rod 8 to slide along the through hole 7 into the casting tank 3, thereby causing the pressing bladder 9 to squeeze the casting mold 5. When the pressing bladder 9 squeezes the casting mold 5 to move it to the right, the spring 11 is compressed. When the pressing plate 10 is released, the contact plate 12 pushes the casting mold 5 to the left under the reset action of the spring 11. By repeatedly pressing the pressing plate 10, the casting mold 5 can move periodically left and right. This periodic horizontal movement of the casting mold 5 allows the casting liquid injected into the casting mold 5 to be distributed quickly and evenly, effectively avoiding local accumulation or uneven distribution of the casting liquid in the mold. This greatly improves the molding efficiency of the ceramic liner and ensures the quality stability of the ceramic liner.

[0021] Please see Figure 1 - Figure 4A valve 201 is installed at the outer end of the pouring pipe 2. The valve 201 is located at the pipe opening of the pouring pipe 2 near the mixing tank 1. By setting the valve 201, the release of the pouring liquid in the mixing tank 1 can be controlled. An anti-slip sleeve 202 is fixedly connected to the outer end of the pouring pipe 2. The anti-slip sleeve 202 is located at the pipe opening of the pouring pipe 2 inside the pouring mold 5. By setting the anti-slip sleeve 202, when the pouring mold 5 moves horizontally, the anti-slip sleeve 202 can buffer the inner wall of the pouring mold 5 and prevent the pouring pipe 2 from being damaged when it comes into contact with the pouring pipe 2.

[0022] Please see Figure 2 - Figure 3 A distance sensor 301 is installed on the inner wall of the casting tank 3. By setting the distance sensor 301, the distance between the liquid surface of the casting liquid can be detected when the casting mold 5 moves, so as to confirm whether the casting liquid in the casting mold 5 has been evenly distributed. A polished layer is provided at the contact point between the guide rail 4 and the slider 6. By setting the polished layer, the slider 6 can slide more smoothly on the guide rail 4.

[0023] Please see Figure 5 A limiting ring 801 is fixedly connected to the outer end of the insertion rod 8. The limiting ring 801 is located between the pressing bladder 9 and the casting tank 3. By setting the limiting ring 801, the pressing bladder 9 is less likely to come into contact with the inner wall of the casting tank 3, thus making the connection between the pressing bladder 9 and the casting tank 3 less likely to be damaged. The surface of the pressing plate 10 is engraved with anti-slip texture. By setting the anti-slip texture on the surface of the pressing plate 10, it is not easy for technicians to slip when pressing the pressing plate 10, thereby improving the work efficiency of technicians.

[0024] The working principle of the above embodiments is as follows: In use, technicians press the pressing plate 10 and release it, causing the pressing plate 10 to push the insert rod 8 along the through hole 7 into the casting tank 3. This causes the pressing bladder 9 to exert force on the casting mold 5. With the sliding action between the slider 6 and the guide rail 4, the casting mold 5 can move to the right, compressing the spring 11. Under the reset action of the spring 11, the contact plate 12 can push the casting mold 5 to the left, thus realizing the movement of the casting mold 5. Technicians can further realize the periodic left and right movement of the casting mold 5 by repeatedly pressing the pressing plate 10, so that the casting liquid in the casting mold 5 can be evenly distributed. Compared with the prior art, this utility model can realize the rapid distribution of the injected casting liquid by shaking the casting mold in the horizontal direction, thereby improving the molding efficiency of ceramic liner.

[0025] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
