Description

Technical Field

[0001] This utility model belongs to the field of ceramic tile production technology, specifically relating to an isostatic pressing upper mold for ceramic tile production with pressure regulation function. Background Technology

[0002] In modern ceramic tile manufacturing processes, isostatic pressing technology has become a key step in ceramic tile manufacturing due to its ability to impart high density, high strength, and uniform internal structure to ceramic tiles. As the core component of this technology, the performance of the isostatic pressing upper mold directly affects the production quality and efficiency of ceramic tiles.

[0003] Currently, in terms of equipment maintenance, the telescopic rods of existing isostatic pressing molds lack an effective automatic lubrication mechanism. Due to the frequent extension and retraction of the telescopic rods during the tile pressing process, after long-term use, the lack of timely and sufficient lubrication easily leads to severe wear and jamming. Once the telescopic rods malfunction, it will not only cause equipment downtime for repair and increase maintenance costs, but also seriously affect the production schedule and disrupt the company's production plan. Therefore, those skilled in the art provide an isostatic pressing mold for tile production with pressure regulation function to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed isostatic pressing upper mold for ceramic tile production with pressure regulation function in order to solve the above problems.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: It includes a mounting plate, on which hydraulic rods are installed at both sides of the bottom center of the mounting plate, and at each of the four corners of the bottom of the mounting plate, a connecting seat is installed at the bottom of the telescopic rod, and a lubrication assembly is installed at the output end of the hydraulic cylinder. The lubrication assembly includes a fixed sleeve plate fixedly fitted onto the outer wall of the movable end of the hydraulic rod, a driven plate installed on the side wall of each of the two fixed sleeve plates, and a connecting plate installed on the side wall of each of the two driven plates, located on one side of the telescopic rod. An oil reservoir is installed on the side wall of each telescopic rod, and a piston rod is movably connected to the top of the oil reservoir. An oil storage groove is formed on the inner side wall of the oil reservoir, and a lubrication groove is formed on the inner side wall of the telescopic rod. An oil outlet is connected between the oil storage groove and the lubrication groove.

[0006] As a further optimization of this utility model, the four connecting plates are arranged in a rectangular array, and a piston is slidably connected to the bottom of the piston rod and located on the inner wall of the oil storage tank.

[0007] As a further optimization of this utility model, the top of the piston rod is fixedly connected to the bottom of the corresponding connecting plate, and the side wall of the oil storage tank is provided with an oil injection hole communicating with the oil storage tank.

[0008] As a further optimization of this utility model, a support plate is installed on the other side wall of the driven plate, and a spring is installed at the bottom of each support plate. The bottom of the spring is fixedly installed on the top of the connecting seat.

[0009] As a further optimization of this utility model, a pressure plate is fixedly installed at the bottom of the connecting seat, and an upper mold base is fixedly installed at the bottom of the pressure plate.

[0010] As a further optimization of this utility model, a material box is installed on the top of the pressure plate, and a discharge hole is opened on the top of the upper mold base, with the material box communicating with the discharge hole.

[0011] The beneficial effects of this utility model are as follows: 1. In this utility model, a lubrication component is provided at the output end of the hydraulic rod. When the hydraulic cylinder is operating, the piston rod is driven to slide in the oil storage tank through the linkage of the fixed sleeve plate, the driven plate and the connecting plate, so that the lubricating oil flows into the lubrication tank automatically through the oil outlet hole, thereby realizing real-time lubrication of the telescopic rod. This automatic lubrication method eliminates the need for frequent manual addition of lubricating oil, reduces the workload of equipment maintenance, extends the service life of the telescopic rod and reduces the probability of equipment failure.

[0012] 2. This utility model, by setting a flow regulating valve on the top of the mounting plate and connecting it to the hydraulic cylinder via a flow pipe, can precisely control the gas flow entering the hydraulic cylinder, thereby achieving precise adjustment of the pressure plate and upper mold seat pressure. Whether producing ultra-thin or thick ceramic tiles, the pressure can be flexibly adjusted according to actual needs, ensuring the stability and consistency of ceramic tile pressing quality, and greatly improving the product qualification rate and production efficiency.

[0013] 3. In this utility model, telescopic rods and connecting seats are installed at the four corners of the bottom of the mounting plate. Together with the support plate and spring on the side wall of the driven plate, a stable support and buffer structure is formed. When the hydraulic cylinder is operating, the telescopic rods play an auxiliary guiding role, while the springs can effectively buffer the pressure, ensuring the stability of the entire upper mold structure during the pressing process and improving the accuracy and quality of tile pressing.

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0017] like Figure 1 , Figure 3 , Figure 4 As shown, this utility model includes a core component mounting plate 1. Two hydraulic cylinders are symmetrically mounted on the side wall of the mounting plate 1. The output ends of the two hydraulic cylinders are fixed to the two sides of the mounting plate 1, which can provide power output for the pressure adjustment of the upper mold. At the same time, hydraulic rods 4 are installed on both sides of the bottom center of the mounting plate 1, and telescopic rods 5 are installed at the four corners of the bottom of the mounting plate 1. Connecting seats 6 are installed at the bottom of these telescopic rods 5 to stably support the entire upper mold structure and to play an auxiliary guiding and buffering role when the hydraulic cylinders 2 are operating.

[0018] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6As shown, a lubrication assembly 9 is installed at the output end of the hydraulic cylinder 2. The lubrication assembly 9 specifically includes a fixed sleeve plate 911 fixedly sleeved on the outer wall of the movable end of the hydraulic rod 4. Driven plates 901 are respectively installed on the side walls of the two fixed sleeve plates 911. Connecting plates 902 are installed on the side walls of the two driven plates 901, each located on one side of the telescopic rod 5. The four connecting plates 902 are arranged in a rectangular array. Oil reservoirs 905 are installed on the side walls of the telescopic rod 5. A piston rod 906 is movably connected to the top of the oil reservoir 905. A piston 907 is slidably connected to the bottom of the piston rod 906, located on the inner wall of the oil reservoir 909. The top of the piston rod 906 is fixedly connected to the bottom of the corresponding connecting plate 902. The side wall of the oil reservoir 905 has openings for connecting the oil reservoir... The oil filling hole 908 is connected to the groove 909. When not in use, the oil filling hole 908 is sealed with a sealing plug. When oil needs to be added, the sealing plug is removed, and lubricating oil is added to the inner wall of the oil storage tank through the oil supply pipe. The inner side wall of the telescopic rod 5 is provided with a lubrication groove 501. An oil outlet hole 910 is connected between the oil storage tank 909 and the lubrication groove 501. The lubrication groove 601 and the oil outlet hole 910 are located at the bottom of the telescopic rod 5, thus forming a lubrication structure for the telescopic rod 5. Support plates 903 are respectively installed on the other side wall of the driven plate 901. Springs 904 are installed at the bottom of each support plate 903. The bottom of the springs 904 is fixedly installed on the top of the connecting seat 6. The springs 904 provide elastic support for the driven plate 901, ensuring the stable operation of the lubrication assembly 9.

[0019] like Figure 1 , Figure 3 , Figure 4 As shown, a flow regulating valve is connected to the side wall of the hydraulic cylinder via a flow pipe. The flow regulating valve can precisely control the flow rate entering the hydraulic cylinder, thereby realizing the pressure regulation function. An upper mold base 8 is fixedly installed at the bottom of the pressure plate 7 for pressing the ceramic tile. In addition, a material box 2 is installed on the top of the pressure plate 7, and a discharge hole 3 is opened on the top of the upper mold base 8. The material box 2 is connected to the discharge hole 3, which facilitates the material to be transported to the upper mold base 8 for pressing.

[0020] It should be noted that when using this utility model: Upon starting the equipment, the flow regulating valve 3 controls the amount of liquid entering the hydraulic cylinder 2 through the flow pipe 4. The output end of the hydraulic cylinder 2 drives the mounting plate 1 and the fixing sleeve 911 on the outer wall of the hydraulic rod 4 to move downwards. The fixing sleeve 911 drives the driven plate 901 and the connecting plate 902 to move downwards. The connecting plate 902 pulls the piston rod 906 downwards, causing the piston 907 to slide downwards in the oil storage tank 909. The lubricating oil in the oil storage tank 909 enters the lubrication tank 501 through the oil outlet 910 to lubricate the telescopic rod 5. Simultaneously, the hydraulic cylinder pushes the pressure plate 7 and the upper mold base 8 downwards. The material in the material box 2 is transported to the upper mold base 8 through the discharge hole 3 to press the ceramic tile raw material on the upper mold base 8. During the pressing process, the pressure can be adjusted in real time through the flow regulating valve 3 as needed.

[0021] The above-described embodiments are merely examples of several implementations of this utility model. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
