Description

Technical Field

[0001] This utility model relates to the field of press mold changing technology, and in particular to a rapid mold changing system for ceramic brick presses. Background Technology

[0002] In the large-scale production of ceramic tiles, the press, as the core equipment for tile blank forming, needs to press the powder into shape through the mold assembly. When changing product specifications, the corresponding mold assembly must be replaced. The existing mold changing technology has significant drawbacks: the material feeding mechanism on the material feeding side of the press must be removed first, and then the old mold is pushed out to the material feeding side by the press ejection mechanism. Subsequently, manual labor is required in conjunction with a transfer platform to remove the old mold and install the new mold, and finally the material feeding mechanism is restored.

[0003] This process is not only time-consuming, leading to long downtime of the press and reduced production capacity, but also requires a high degree of manual intervention and is labor-intensive. It is prone to mold collision damage or inaccurate positioning due to operational deviations, which affects the quality of the brick blanks. At the same time, the frequent movement of the material feeding mechanism will aggravate the wear and tear of the parts and shorten the service life of the equipment. Utility Model Content

[0004] The purpose of this invention is to propose a rapid mold changing system for ceramic brick presses, so as to solve the technical problems of low mold changing efficiency, high dependence on manual labor, and high equipment wear and tear in the existing technology.

[0005] To achieve this objective, the present invention adopts the following technical solution: A rapid mold changing system for a ceramic tile press includes a press, a mold assembly, a mold lifting mechanism, and a mold changing trolley mechanism; The press includes a frame, a mold mounting base, and a downward telescopic drive cylinder; The frame is mounted on top of the base, and the mold mounting base is mounted on the upper surface of the base. The mold mounting base has a mold cavity inside, which is used for mounting the mold assembly. The mold assembly includes a mold frame and a mold pressure plate. The mold cavity fixes the mold frame by magnetic attraction. A top seat is installed at the top of the frame, and the downward telescopic drive cylinder is installed at the center of the top seat. The downward telescopic drive cylinder is arranged vertically opposite to the mold cavity, and the telescopic end of the downward telescopic drive cylinder fixes the mold pressure plate by magnetic attraction. A window is formed between the mold mounting base and the top base. The mold lifting mechanism is installed inside the base. The telescopic end of the mold lifting mechanism can pass through the mold cavity. The mold lifting mechanism is used to lift or lower the mold assembly located in the mold cavity. The mold changing vehicle mechanism is located on the opposite side of the press fabric side; The mold changing mechanism includes a moving track and two mold changing trolleys. The two mold changing trolleys are movably mounted on the moving track and are used to cooperate with the mold lifting mechanism to replace the mold assembly. Each of the mold changing trolleys is equipped with a telescopic arm and a telescopic transmission mechanism for driving the telescopic arm to extend and retract. The telescopic arm is used to insert into the window portion to receive or transfer the mold assembly.

[0006] Preferably, the telescopic transmission mechanism includes a fixed mounting plate, a telescopic drive cylinder, a gear transmission assembly, and a rack and pinion transmission assembly; The telescopic drive cylinder is mounted on the fixed mounting plate, and the telescopic end of the telescopic drive cylinder is equipped with the gear transmission assembly. The rack and pinion transmission assembly meshes with the gear transmission assembly, and the telescopic arm is fixedly mounted on the rack and pinion transmission assembly.

[0007] Preferably, the gear transmission assembly includes a gear mounting base, a drive gear, and a gear guide rail; The side of the gear mounting base is fixedly connected to the telescopic end of the telescopic drive cylinder via a connector, and the drive gear is rotatably mounted above the gear mounting base via a rotating shaft. A first groove is provided below the gear mounting base. The first groove is adapted to the gear guide rail. The distribution direction of the gear guide rail is set along the extension and retraction direction of the telescopic drive cylinder.

[0008] Preferably, the rack and pinion drive assembly includes a first mounting plate, a second mounting plate, and a rack and pinion guide rail; A first toothed rack is mounted on the side of the first mounting plate, and the first mounting plate is fixedly mounted on the fixed mounting plate; A second rack is mounted on the side of the second mounting plate, and a second groove is provided on the bottom of the second mounting plate. The second groove is adapted to the rack guide rail. The rack guide rail and the gear guide rail are arranged in parallel. The telescopic arm is fixedly mounted on the upper surface of the second mounting plate. The first rack and the second rack are located on both sides of the drive gear and are meshed with the drive gear.

[0009] Preferably, it also includes a control box, which is installed on the side of the mold changing trolley; The control box integrates a control module and a communication module. The communication module is used to communicate with an external host computer, and the control module is used to receive control commands to drive the mold changing trolley. The control box is equipped with a control panel on its exterior, and the control panel is electrically connected to the control module.

[0010] Preferably, the mold lifting mechanism includes a lifting cylinder and a lifting pad. The lifting cylinder is located inside the base. The telescopic rod of the lifting cylinder is vertically upward and the lifting pad is installed at its end. The lifting pad is used to contact the bottom of the mold assembly.

[0011] Preferably, the mold-changing trolley includes a body, wheels and a mold-changing drive motor, and a pair of wheels are connected by a drive shaft, which is connected to the mold-changing drive motor through a transmission mechanism; The wheel has a movable groove that is adapted to the moving track.

[0012] One of the above technical solutions has the following beneficial effects: (1) Significantly improve mold changing efficiency and reduce press downtime: Compared with the cumbersome process of "removing the material feeding mechanism - manual transfer - restoring the material feeding mechanism" in the existing technology, this technical solution sets the mold changing trolley mechanism on the opposite side of the material feeding side of the press, and directly connects to the mold cavity through the window, without moving the material feeding mechanism, thus avoiding the time spent on the displacement and reset of the material feeding mechanism; at the same time, the two mold changing trolleys alternately complete the "removal of the old mold" and "transportation of the new mold", and the mold lifting, magnetic fixation and telescopic arm movement are all automatically controlled, reducing the time of a single mold changing, significantly reducing press downtime and increasing production line capacity.

[0013] (2) Eliminate manual intervention and reduce labor intensity and quality risks: From magnetic release and mold lifting to telescopic arm support and mold transfer, no manual handling or calibration is required, which completely solves the problem of "high degree of manual involvement and high labor intensity" in the existing technology. At the same time, through the combined design of "magnetic fixing + mold lifting mechanism alignment + telescopic arm precise pushing", it is ensured that the mold assembly is not displaced or bumped during the transfer and installation process, avoiding problems such as mold damage and unqualified brick blank forming dimensions caused by manual operation deviation, and reducing the production rework rate.

[0014] (3) Reduce equipment wear and extend equipment service life: There is no need to move the cloth feeding mechanism, which avoids the wear of the guide rail and the aging of the drive components caused by frequent displacement of the cloth feeding mechanism, and extends the maintenance cycle and service life of the cloth feeding mechanism; at the same time, the mold assembly is smoothly supported and transferred by the telescopic arm, and there is no hard friction with the inner wall of the mold cavity and the edge of the window; at the same time, the magnetic fixing method replaces the traditional mechanical clamping, which reduces the mechanical wear of the mold frame and the mold cavity, and reduces the maintenance cost of the press and the mold.

[0015] (4) Stable and reliable structure with strong adaptability: The mold frame and mold cavity, mold pressure plate and downward telescopic drive cylinder are all magnetically fixed, which not only ensures the structural stability during molding, but also facilitates quick release of fixation when changing molds, making operation flexible; at the same time, the window design can be adapted to mold assemblies of different thicknesses, and the design of two mold changing trolleys moving along the track can adjust the mold changing area according to the installation space of the press, adapting to different specifications of ceramic tile production lines, with a wide range of applications.

[0021] A rapid mold changing system for a ceramic tile press includes a press 1, a mold assembly 2, a mold lifting mechanism 3, and a mold changing trolley mechanism; The press 1 includes a frame 11, a mold mounting base 12, and a downward telescopic drive cylinder 13; The frame 11 is mounted above the base 14, and the mold mounting base 12 is mounted on the upper surface of the base 14. The mold mounting base 12 has a mold cavity 120 inside, which is used for mounting the mold assembly 2. The mold assembly 2 includes a mold frame 21 and a mold pressure plate 22. The mold cavity 120 fixes the mold frame 21 by magnetic attraction. A top seat 15 is installed at the top of the frame 11, and the downward telescopic drive cylinder 13 is installed at the center of the top seat 15. The downward telescopic drive cylinder 13 is arranged vertically opposite to the mold cavity 120. The telescopic end of the downward telescopic drive cylinder 13 fixes the mold pressure plate 22 by magnetic attraction. A window 8 is formed between the mold mounting base 12 and the top base 15. The mold lifting mechanism 3 is installed in the base 14. The telescopic end of the mold lifting mechanism 3 can pass through the mold cavity 120. The mold lifting mechanism 3 is used to lift or lower the mold assembly 2 located in the mold cavity 120. The mold changing vehicle mechanism is located on the opposite side of the fabric side of the press 1; The mold changing mechanism includes a moving track 4 and two mold changing trolleys 5. The two mold changing trolleys 5 are movably arranged on the moving track 4. The two mold changing trolleys 5 are used to cooperate with the mold lifting mechanism 3 to replace the mold assembly 2. Each of the mold changing trolleys 5 is provided with a telescopic arm 10 and a telescopic transmission mechanism 9 for driving the telescopic arm 10 to extend or retract. The telescopic arm 10 is used to insert into the window portion 8 to receive or transfer the mold assembly 2.

[0022] like Figure 1-6 As shown, compared with the prior art, the rapid mold changing system for ceramic tile presses of this utility model uses two mold changing trolleys 5 to alternately complete the connecting actions of "removing the old mold" and "installing the new mold," requiring no manual intervention and eliminating the need to move the material feeding mechanism of the press 1 throughout the process. This significantly shortens the mold changing time and achieves automated and efficient mold changing. The rapid mold changing system for ceramic tile presses of this utility model mainly revolves around three stages: "normal pressing - removal of the old mold assembly - installation of the new mold assembly," and the specific principle is as follows: (a) Normal pressing stage of brick blanks by the press During the ceramic brick blank forming process, the press 1 achieves stable fixation of the mold assembly 2 through a magnetic attraction structure: the mold frame 21 of the mold assembly 2 is precisely fixed within the mold cavity 120 of the mold mounting base 12 by the magnetic attraction of the mold cavity 120, ensuring that the mold frame 21 does not shift during the powder placement and pressing process; while the mold pressure plate 22 of the mold assembly 2 is fixed to the telescopic end of the downward telescopic drive cylinder 13 on the top seat 15 of the frame 11 by magnetic attraction. During operation, the downward telescopic drive cylinder 13 drives the mold pressure plate 22 to extend downward, pressing the powder placed in the mold frame 21 into a brick blank. After the forming is completed, the downward telescopic drive cylinder 13 retracts, driving the mold pressure plate 22 to reset, waiting for the next forming or mold changing operation.

[0023] (ii) Removal of old mold assembly When it is necessary to replace the mold assembly to switch product specifications, remove the old mold by following these steps: Press down the telescopic drive cylinder 13 to extend downwards, so that the magnetic attraction function of its telescopic end is turned off (the electromagnet stops working), and the mold pressure plate 22 falls naturally after losing its magnetic force and is placed stably in the mold frame 21, forming a complete old mold assembly. The mold lifting mechanism 3 installed in the base 14 is activated, and its telescopic end passes upward through the mold cavity 120, lifting the old mold assembly (mold frame 21 + mold pressure plate 22) in the mold cavity 120 horizontally, so that the old mold assembly is separated from the inner wall of the mold cavity 120, forming a hollow gap that allows the telescopic arm 10 to be inserted.

[0024] The mold changing trolley mechanism located on the opposite side of the press fabric side is activated. The first unloaded mold changing trolley 5 moves along the moving track 4 to the position corresponding to the window 8. Its telescopic transmission mechanism 9 drives the telescopic arm 10 to extend horizontally and insert it into the hollow gap below the old mold assembly through the window 8 until the telescopic arm 10 fully supports the old mold assembly. Subsequently, the telescopic end of the mold lifting mechanism 3 slowly descends. After the old mold assembly is completely placed on the telescopic arm 10, the telescopic transmission mechanism 9 drives the telescopic arm 10 to retract, pulling the old mold assembly from the window 8 onto the mold changing trolley 5. The mold changing trolley 5 then moves away along the moving track 4, freeing up the mold changing station.

[0025] (III) New mold assembly installation stage The second mold changing trolley 5, carrying the new mold assembly (new mold frame 21 + new mold pressure plate 22), moves along the moving track 4 to the corresponding position of the window section 8. The telescopic transmission mechanism 9 drives the telescopic arm 10 to extend and push the new mold assembly through the window section 8 directly below the mold cavity 120 (coaxially aligned with the mold cavity 120). Then, the telescopic end of the mold lifting mechanism 3 extends upward, lifts the new mold assembly and separates it from the telescopic arm 10, and then the telescopic arm 10 retracts and resets under the drive of the telescopic transmission mechanism 9. The second mold changing trolley 5 returns to the initial position along the moving track 4.

[0026] The mold lifting mechanism 3 is activated again, lowering the new mold assembly (new mold frame 21 + new mold pressure plate 22) to a preset position within the mold cavity 120. The mold cavity 120 then activates its magnetic attraction function to fix the new mold frame 21. Subsequently, the downward telescopic drive cylinder 13 extends downward, and its telescopic end activates its magnetic attraction function to attract the mold pressure plate 22 of the new mold assembly. Then, the downward telescopic drive cylinder 13 retracts, causing the mold pressure plate 22 to return to its initial working position, completing the installation of the new mold assembly.

[0027] At this point, the entire mold-changing process is complete, and press 1 can proceed to the molding operation of new-specification brick blanks.

[0028] To further explain, the telescopic transmission mechanism 9 includes a fixed mounting plate 91, a telescopic drive cylinder 92, a gear transmission assembly 93, and a rack and pinion transmission assembly 94; The telescopic drive cylinder 92 is mounted on the fixed mounting plate 91. The telescopic end of the telescopic drive cylinder 92 is equipped with the gear transmission assembly 93. The rack and pinion transmission assembly 94 meshes with the gear transmission assembly 93. The telescopic arm 10 is fixedly mounted on the rack and pinion transmission assembly 94.

[0029] like Figure 6 As shown, the telescopic transmission mechanism 9 is supported by the fixed mounting plate 91. When the telescopic arm 10 needs to be extended or retracted, the external control signal triggers the telescopic drive cylinder 92 to start. The output end of the telescopic drive cylinder 92 drives the gear transmission assembly 93 to move. Since the gear transmission assembly 93 and the rack transmission assembly 94 mesh with each other, the rotational motion of the gear in the gear transmission assembly 93 is converted into the linear motion of the rack in the rack transmission assembly 94. This drives the telescopic arm 10, which is fixedly connected to the rack transmission assembly 94, to extend or retract synchronously, realizing the precise displacement of the telescopic arm 10 inside and outside the mold cavity 120, and providing power for the receiving and transfer of the mold assembly 2.

[0030] To further explain, the gear transmission assembly 93 includes a gear mounting base 931, a drive gear 932, and a gear guide rail 933; The side of the gear mounting base 931 is fixedly connected to the telescopic end of the telescopic drive cylinder 92 via a connector 934, and the drive gear 932 is rotatably mounted above the gear mounting base 931 via a rotating shaft 935. A first groove is provided below the gear mounting base 931. The first groove is adapted to the gear guide rail 933. The distribution direction of the gear guide rail 933 is arranged along the extension and retraction direction of the telescopic drive cylinder 92.

[0031] like Figure 6 As shown, in the gear transmission assembly 93, the gear mounting base 931 is fixed to the telescopic end of the telescopic drive cylinder 92 via a connector 934, forming a power transmission link. When the telescopic drive cylinder 92 outputs power, it drives the gear mounting base 931 to move along the gear guide rail 933, and the first groove below the gear mounting base 931 is adapted to the gear guide rail 933 to ensure stable movement direction; at the same time, the drive gear 932, which is rotatably mounted on the gear mounting base 931, moves synchronously with the gear mounting base 931 and meshes with the rack and pinion transmission assembly 94, converting the power of the telescopic drive cylinder 92 into the driving force of meshing transmission, providing gear-side power support for the rack and pinion transmission assembly 94 to drive the telescopic arm 10 to move, ensuring the stability and accuracy of the transmission process.

[0032] To further explain, the rack and pinion drive assembly 94 includes a first mounting plate 941, a second mounting plate 942, and a rack and pinion guide rail 943; A first rack 944 is mounted on the side of the first mounting plate 941, and the first mounting plate 941 is fixedly mounted on the fixed mounting plate 91; A second rack 945 is mounted on the side of the second mounting plate 942, and a second groove is provided below the second mounting plate 942. The second groove is adapted to the rack guide rail 943. The rack guide rail 943 and the gear guide rail 933 are arranged in parallel. The telescopic arm 10 is fixedly installed on the upper surface of the second mounting plate 942. The first rack 944 and the second rack 945 are located on both sides of the drive gear 932 and are meshed with the drive gear 932.

[0033] like Figure 6 As shown, in the rack and pinion drive assembly 94, the first mounting plate 941 is fixed on the fixed mounting plate 91, and the first rack 944 on its side is a fixed rack used to form a meshing reference with the drive gear 932 of the gear drive assembly 93; the second rack 945 on the side of the second mounting plate 942 is a movable rack that meshes with the drive gear 932. When the drive gear 932 moves under the drive of the gear drive assembly 93, the meshing action of the drive gear 932 and the second rack 945 pushes the second mounting plate 942 to move along the rack guide rail 943, and the second groove below the second mounting plate 942 is adapted to the rack guide rail 943 to restrict the direction of movement; since the telescopic arm 10 is fixedly installed above the second mounting plate 942, the linear movement of the second mounting plate 942 directly drives the telescopic arm 10 to extend or retract, realizing the receiving and transfer of the mold assembly 2, and the structural design of the double rack and guide rail further improves the accuracy of the displacement of the telescopic arm 10.

[0034] Further explanation includes a control box 6, which is installed on the side of the mold changing trolley 5; the control box 6 integrates a control module and a communication module, the communication module is used to communicate with an external host computer, and the control module is used to receive control commands to drive the mold changing trolley; the control box 6 is provided with a control panel 7 on the outside, and the control panel 7 is electrically connected to the control module.

[0035] like Figure 4-5 As shown, the control box 6 establishes a data connection with the external host computer through the internally integrated communication module, and can receive mold changing instructions sent by the host computer in real time (such as mold changing start, telescopic arm extension distance, mold changing trolley movement position, etc.). The communication module transmits the instructions to the control module. After parsing the instructions, the control module generates corresponding drive signals and sends them to the drive motor of the mold changing trolley 5, the telescopic drive cylinder of the telescopic transmission mechanism 9 and other actuators to control the movement of the mold changing trolley 5 and the action of the telescopic arm 10.

[0036] Meanwhile, the control panel 7 serves as a human-machine interface, allowing operators to manually input control commands (such as emergency stop and parameter fine-tuning). These commands are directly transmitted to the control module, enabling both manual and automatic control by the host computer, thus improving the system's operational flexibility and emergency response capabilities.

[0037] To further explain, the mold lifting mechanism 3 includes a lifting cylinder 31 and a lifting pad 32. The lifting cylinder 31 is located inside the base 14. The telescopic rod 33 of the lifting cylinder 31 is vertically upward and the lifting pad 32 is installed at its end. The lifting pad 32 is used to contact the bottom of the mold assembly 2.

[0038] like Figure 2-3 As shown, the mold lifting mechanism 3 is fixedly supported by the base 6. When the mold assembly 2 needs to be lifted, the external hydraulic system supplies oil to the lifting cylinder 31. Under hydraulic pressure, the telescopic rod 33 of the lifting cylinder 31 extends vertically upward, driving the lifting pad 32 installed at the end to rise synchronously until the lifting pad 32 contacts the bottom of the mold assembly 2 and stops. The lifting pad 32 increases the contact area with the mold assembly 2, preventing uneven force on the mold assembly 2 during the lifting process and thus preventing it from tilting.

[0039] When the telescopic arm 10 of the mold changing trolley 5 is inserted and the mold assembly 2 needs to be lowered, the hydraulic system controls the lifting cylinder 31 to return oil, and the telescopic rod 33 drives the lifting pad 32 to slowly descend. The mold assembly 2 descends synchronously with the lifting pad 32, so that the mold assembly 2 is completely placed on the telescopic arm 10.

[0040] To further explain, the mold-changing trolley 5 includes a body 51, wheels 52 and a mold-changing drive motor 53. A pair of wheels 52 are connected by a drive shaft 54, and the drive shaft 54 ​​is connected to the mold-changing drive motor 53 through a transmission mechanism 55. The wheel 52 has a movable groove 56, which is adapted to the moving track 4.

[0041] like Figure 5 As shown, the mold changing trolley 5 has a main frame of body 51. When it needs to move along the moving track 4, the mold changing drive motor 53 starts, and its output power is transmitted to the drive shaft 54 ​​through the transmission mechanism 55 (such as chain drive, belt drive or gear drive). The drive shaft 54 ​​rotates under the action of power, driving the wheels 52 fixedly connected at both ends to rotate synchronously. Since the wheels 52 have moving grooves 56 that are adapted to the moving track 4, the cooperation between the moving grooves 56 and the moving track 4 restricts the movement direction of the wheels 52, so that the mold changing trolley 5 moves in a straight line along the moving track 4, realizing the precise movement of the mold changing trolley 5 between different workstations outside the mold cavity 120, and providing workstation switching support for the handover of the mold assembly 2.

[0042] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
