Description

Technical Field

[0001] This utility model relates to the field of ceramic hot pressing technology, and in particular to a fully automatic ceramic hot pressing device. Background Technology

[0002] A ceramic hot pressing device is a specialized piece of equipment used to prepare high-performance ceramic materials, integrating powder forming and high-temperature sintering processes. In existing technologies, this device typically includes a heating system, a pressure system, a mold, and a control system. By applying unidirectional or bidirectional mechanical pressure to ceramic powder or green bodies at high temperatures, it promotes material densification and grain growth, thereby obtaining ceramic products with uniform structure and excellent performance.

[0003] A search revealed that patent CN219276144U discloses a fully automatic special ceramic hot pressing machine. It lifts the feed pipe to the guide block position and then transports the ceramic slurry into the mold for hot pressing through the connecting pipe, output pipe, guide block, and feed pipe. This allows the position of the output pipe to be adjusted according to the position of the feed pipe, thereby improving work efficiency.

[0004] However, the above-mentioned device shares the same drawbacks as existing ceramic hot pressing devices: current hot pressing devices for producing smaller ceramic parts use conveyor belts to receive the molded material; however, when producing larger ceramic parts, manual removal of the molded ceramic parts from the mold is still required; similarly, the above-mentioned device lacks an automatic material handling mechanism, necessitating manual material handling, resulting in high labor intensity and certain safety risks. Therefore, further improvements are needed. To this end, we propose a fully automatic ceramic hot pressing device. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a fully automatic ceramic hot pressing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic ceramic hot pressing device, comprising a base plate, a mold assembly, a chiller unit, a grouting machine, and a control system. A support plate is fixed to the upper surface of the base plate via multiple support rods. A top plate is connected to the upper surface of the support plate via multiple support rods, and a hydraulic telescopic rod is fixed to the upper surface of the top plate. The mold assembly includes a bottom mold fixed to the upper surface of the support plate and a top mold fixed to the bottom telescopic end of the hydraulic telescopic rod. An opening is provided on one side of the support plate, and a collection box is disposed inside the opening. A lifting assembly for driving the collection box to rise and fall is installed on the upper surface of the base plate. A gripping assembly is disposed above the collection box. A servo motor for driving the gripping assembly to rotate horizontally is fixed in the middle of the lower surface of the support plate.

[0007] Furthermore, the bottom mold has a mold cavity on its upper surface, and the top mold has a grouting port in the middle that communicates with the mold cavity. The grouting port is connected to the grouting end of the grouting machine through a pipe.

[0008] Furthermore, a serpentine cooling channel is provided inside the bottom end of the bottom mold, and the two ends of the cooling channel are respectively connected to the water inlet and water outlet of the chiller unit.

[0009] Furthermore, the gripping component includes a horizontal plate, on one side of the upper surface of the horizontal plate a cylinder is fixed, and a plurality of suction cups are fixedly connected to the telescopic end of the bottom of the cylinder, and a negative pressure pump is provided to match the suction cups.

[0010] Furthermore, a drive shaft is fixed to the top output end of the servo motor, and the top end of the drive shaft is fixedly connected to the lower surface of the horizontal plate.

[0011] Furthermore, the lifting assembly includes two electrically operated telescopic rods fixed to the upper surface of the base plate, and the top telescopic ends of the two electrically operated telescopic rods are jointly fixedly connected to a tray, and the collection box is placed on the upper surface of the tray.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a fully automatic ceramic hot pressing device is disclosed, comprising a base plate 1, a mold assembly 4, a chiller unit 6, a grouting machine, and a control system. A support plate 2 is fixed to the upper surface of the base plate 1 by multiple support rods. A top plate 3 is connected to the upper surface of the support plate 2 by multiple support rods, and a hydraulic telescopic rod 5 is fixed to the upper surface of the top plate 3. The mold assembly 4 includes a bottom mold 41 fixed to the upper surface of the support plate 2 and a top mold 42 fixed to the bottom telescopic end of the hydraulic telescopic rod 5. An opening 21 is provided on one side of the support plate 2, and a collection box 7 is provided inside the opening 21. A lifting assembly 8 for driving the collection box 7 to rise and fall is installed on the upper surface of the base plate 1. A gripping assembly 9 is provided above the collection box 7. A servo motor 10 for driving the gripping assembly 9 to rotate horizontally is fixed in the middle of the lower surface of the support plate 2.

[0023] The bottom mold 41 has a mold cavity 43 on its upper surface, and the top mold 42 has a grouting port 44 in the middle that communicates with the mold cavity 43. The grouting port 44 is connected to the grouting end of the grouting machine through a pipe.

[0024] In this embodiment, the control system of the hot pressing device adopts the existing control system of the grouting machine, specifically a Siemens controller with screen: SIMATIC KP1200 series (HMI+PLC integrated machine) KP1212BasicPN, which controls the operation of the device and the grouting machine.

[0025] During the grouting and hot pressing process, the hydraulic telescopic rod 5 extends and drives the top mold 42 to descend and close with the bottom mold 41. Then, the grouting machine injects ceramic slurry into the grouting port 44. The ceramic slurry enters the mold cavity 43, allowing the ceramic part to be formed in the mold cavity 43.

[0026] The bottom mold 41 has a serpentine cooling channel 45 inside, and the two ends of the cooling channel 45 are connected to the water inlet and water outlet of the chiller unit 6, respectively.

[0027] Similarly, the chiller unit 6 adopts the existing model. The chiller unit 6 can circulate cold water into the cooling channel 45. After the ceramic slurry is pressed and formed in the mold cavity 43, the ceramic slurry can be cooled through the cooling channel 45 to accelerate the forming process.

[0028] The gripping component 9 includes a horizontal plate 91, a cylinder 92 is fixed on one side of the upper surface of the horizontal plate 91, and a number of suction cups 93 are fixedly connected to the bottom telescopic end of the cylinder 92. A negative pressure pump is provided to match the suction cups 93.

[0029] In this embodiment, the negative pressure pump and the suction cup 93 are connected by a flexible hose, and an electronic three-way valve is connected between them. After the negative pressure pump is started, it can pick up the ceramic part through the suction cup 93. When the electronic three-way valve is controlled, the ceramic part is released during exhaust.

[0030] The top output end of the servo motor 10 is fixed with a drive shaft 11, and the top end of the drive shaft 11 is fixedly connected to the lower surface of the horizontal plate 91.

[0031] In this embodiment, the model of servo motor 10 can be flexibly selected according to cost. When the servo motor 10 is controlled to rotate forward or reverse by the control system, the horizontal plate 91 can be driven to rotate forward or reverse 180° through the drive shaft 11, so that the gripping component 9 rotates alternately above the bottom mold 41 and the collection box 7.

[0032] The lifting assembly 8 includes two electric telescopic rods 81 fixed to the upper surface of the base plate 1. The top telescopic ends of the two electric telescopic rods 81 are fixedly connected to a tray 82, and the collection box 7 is placed on the upper surface of the tray 82.

[0033] Since there are always ceramic parts stacked inside the collection box 7, and the extension length of the cylinder 92 is fixed, each time a ceramic part is put into the collection box 7, the control system controls the electric telescopic rod 81 to shorten the specified stroke, thereby driving the tray 82 to descend, so that the collection box 7 can descend, so that the gripping component 9 can continue to put ceramic parts into the collection box 7.

[0034] Working principle: During hot pressing, the hydraulic telescopic rod 5 first extends to drive the top mold 42 and the bottom mold 41 to close. Then, the grouting machine injects ceramic slurry into the mold cavity 43 from the grouting port 44. During the pressure holding period, the chiller unit 6 injects cold water into the cooling channel 45 to cool the ceramic parts and accelerate the molding.

[0035] After the ceramic part is formed, the hydraulic telescopic rod 5 shortens, causing the top mold 42 to rise and reset. Then, the servo motor 10 starts, using the drive shaft 11 to rotate the horizontal plate 91 180°, positioning the suction cup 93 above the mold cavity 43. The cylinder 92 then extends until the suction cup 93 is in contact with the ceramic part. At this point, the negative pressure pump starts, using the suction cup 93 to grip the ceramic part. Once the grip is stable, the cylinder 92 shortens, causing the ceramic part to be removed from the mold cavity 43. Next, the servo motor 10 reverses the horizontal plate 91, causing the ceramic part to rotate above the collection box 7. Finally, the cylinder 92 extends, causing the ceramic part to fall into the collection box 7. Then, the electric telescopic rod 81 lowers the support plate 82 and the collection box 7 by a specified stroke, preparing for the next material reception.

[0036] In this embodiment, the electrical connection methods between each electric component and the control system, as well as the control program, are all existing technologies and will not be described in detail here. This solution only improves the structure and does not affect the realization of the overall function.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
