Description

Technical Field

[0001] This utility model belongs to the technical field of ceramic production equipment, specifically relating to a high-pressure mold frame pressurization system. Background Technology

[0002] Traditional sanitary ceramic factories, when making high-pressure mold iron frames, usually close and pressurize a set of mold frames for 3-4 hours before going online after applying the resin layer, so as to flatten the molding surface as much as possible and avoid leakage of grout during later grouting due to uneven molding surface.

[0003] There are two existing pressing methods. One method involves placing the mold frame on a flat surface and applying a weight on top. This method typically uses existing mold frames. Its advantages are simplicity and convenience, allowing for easy adjustment of the number of molds to be pressed. However, its disadvantage is insufficient pressure, resulting in a large discrepancy with the actual slurry pressure in production, making it impossible to achieve adequate flattening. The second method involves mounting the mold frame onto a horizontal molding machine and pressing multiple sets at once. This method offers high pressure, consistent with actual production pressure, and good flatness of the molded surface after pressing. However, its disadvantage is that it is only suitable for mass production, and the mold frames used for pressing must be of uniform size. It is inconvenient to use for small batches where only 1-2 sets of mold frames need to be pressed. Utility Model Content

[0026] Example 1

[0027] This embodiment provides a high-pressure mold frame pressurization system, including a conveying device and a mold frame pressurizer 2, wherein the conveying device is located on one side of the mold frame pressurizer 2;

[0028] The mold frame press 2 includes a frame 201, a pressurizing device and a moving device. The pressurizing device is connected to the frame 201 and is connected to a pressure plate 203. The conveying device is used to hoist the frame onto the moving device, and the moving device is used to transport the frame to a position below the pressurizing device.

[0029] The high-pressure mold frame pressurization system provided by this utility model uses a conveying device to hoist the frame onto the moving device of the mold frame pressurizer 2. The moving device then transports the mold frame 3 to the bottom of the pressurizing device, pressurizes it to the working pressure, and flattens the mating surface of the mold frame 3 through the pressure plate 203, thereby reducing the probability of grout leakage.

[0030] Example 2

[0031] Based on Example 1, this example provides a high-pressure mold frame pressurization system, such as... Figure 2 As shown, the mold frame press 2 also includes a base 204 and a track 205. The moving device is a moving trolley 207. The track 205 is disposed on the base 204, and the moving trolley 207 is rotatably connected to the track 205.

[0032] Work process:

[0033] The transport device hoists the frame onto the mobile trolley 207. The mobile trolley 207 moves along the track 205 to below the pressurizing device. The pressurizing device drives the pressure plate 203 to move downward to pressurize the frame.

[0034] Example 3

[0035] Based on Embodiment 2, this embodiment provides a high-pressure mold frame pressurization system, which also includes a control system. An encoder is installed on the motor shaft of the motor of the mobile trolley 207, and both the motor and the encoder are electrically connected to the control system.

[0036] The initial position of the mobile trolley 207 is the waiting position, located at one end of the track 205 away from the frame 201, waiting for the transport device to lift the frame onto the mobile trolley 207. Once the frame is loaded onto the mobile trolley 207, the control system sends a signal to the motor, which rotates, and the mobile trolley 207 begins to move along the track 205 towards the frame 201. During the movement, the encoder sends displacement data to the control system in real time. When the mobile trolley 207 reaches the set displacement, the control system sends a stop signal to the motor, causing the mobile trolley 207 to stop moving, and the pressurizing device begins to pressurize the frame.

[0037] Example 4

[0038] Based on Embodiment 2, this embodiment provides a high-pressure mold frame pressurization system, wherein the conveying device is a crane 1, the frame 201 is located at one end of the track 205, and the other end of the track 205 extends into the range of the crane 1.

[0039] like Figure 1 As shown, the mold frame 3 is hoisted onto the mobile device by the overhead crane 1, and then pushed by the operator to the bottom of the mold frame press 2. Since the trolley is pushed by rolling friction, the whole set of actions can be completed by a single person, which is simple and labor-saving.

[0040] Example 5

[0041] Based on Embodiment 3, this embodiment provides a high-pressure mold frame pressurization system. The pressurization device is a hydraulic cylinder 202. The base 204 of the hydraulic cylinder 202 is fixedly connected to the inner side of the top of the frame 201. The telescopic rod of the hydraulic cylinder 202 is connected to the pressure plate 203.

[0042] The oil cylinder 202 and the hydraulic station 208 are connected by a pipeline, and a proportional regulating valve is provided on the pipeline. The proportional regulating valve is connected to the control system by electrical signal.

[0043] After the mold frame 3 is in place, the hydraulic oil in the hydraulic station 208 pushes the extension rod of the cylinder 202 to extend, pushing the pressure plate 203 downward to pressurize the mold frame 3. According to the actual working pressure requirements, the proportional adjustment valve of the pressurizing device is proportionally adjusted by the control system to make the resin layer on the molding surface meet the extrusion requirements.

[0044] Example 6

[0045] Based on Example 1, this example provides a high-pressure mold frame pressurization system, which also includes a guiding device, such as... Figure 2 As shown, the guide device is symmetrically arranged on both sides of the pressurizing device. The upper end of the guide device is connected to the inner side of the top of the frame 201, and the lower end of the guide device is connected to the pressure plate 203.

[0046] The guiding device includes a guide post 206 and a guide sleeve. The guide sleeve is fixed on the upper surface of the pressure plate 203. One end of the guide post 206 is connected to the inner side of the top of the frame 201, and the other end of the guide post 206 is inserted into the guide sleeve.

[0047] The guide device enables the pressure plate 203 to be pressed down synchronously, so that the resin layer on the molding surface is squeezed evenly under the same pressure, further preventing slurry leakage.

[0048] Example 7

[0049] Based on Example 5, this example provides a high-pressure mold frame pressurization system, wherein the control system is a PLC control system.

[0050] A PLC control system includes a PLC controller, digital input modules, digital output modules, analog input modules, and analog output modules.

[0051] The encoder is a digital encoder that converts linear displacement into digital electrical signals, which are then fed back to the PLC controller via a digital module. The output setting of the proportional control valve is determined by the digital output module.

[0052] Example 8

[0053] Based on Example 1, this example provides a high-pressure mold frame pressurization system, such as... Figure 2 As shown, it includes an overhead crane 1 and a mold frame press 2. The mold frame press 2 consists of a frame, a hydraulic cylinder 202, a pressure plate 203, a base 204, a rail 205, a guide column 206, a moving trolley 207, and a hydraulic station 208.

[0054] like Figure 2As shown, the mold frame press 2 is located on one side of the end of the overhead crane 1, and the track 205 extends into the range of the overhead crane 1. The mold frame 3 is hoisted by the overhead crane 1 onto the moving trolley 207, and then the operator pushes the moving trolley 207 to or controls the control system to move it to below the pressure plate 203. The hydraulic station 208 outputs pressure to push the pressure plate 203 down, and the mold frame 3 is uniformly and synchronously pressed under the action of the guide column 206.

[0055] The pressurization system allows for selection of the number of pressurization mold frames (3) based on actual conditions. It is suitable for small-batch high-pressure extrusion mold frame mating surfaces, flattening the mating surface and reducing the chance of slurry leakage. The control system controls the pressure of the moving trolley 207 and the hydraulic cylinder 202, improving system accuracy and automation. The entire set of equipment requires only one person to operate, making it simple, labor-saving, and worthy of widespread application.
