Description

Technical Field

[0001] This utility model relates to the field of brick machine technology, and in particular to a static pressure brick forming mechanism. Background Technology

[0002] Static pressure brick machine is an important type of construction machinery. It mainly uses strong static pressure to press various raw materials into bricks, such as curb stones, wall bricks, and floor tiles.

[0003] In traditional static pressure brick forming machines, a single station is typically used for pressing and forming brick blanks. This single-station operation has significant efficiency bottlenecks. For example, while the main hydraulic cylinder drives the die to press and hold the material in the lower cavity, the upper cavity is often idle, waiting for the brick blank in the lower cavity to complete forming and be removed before material filling can begin. This sequential workflow results in substantial waiting time, meaning the reciprocating movement of the main hydraulic cylinder is not fully utilized. Furthermore, the single-station operation limits the parallel processing capacity of the production line, making it difficult to further improve production efficiency. Simultaneously, the longer production cycle increases the unit brick blank production cost, reducing the product's market competitiveness. Utility Model Content

[0004] This utility model proposes a static pressure brick forming mechanism, which solves the problem of low brick production efficiency in the prior art.

[0005] The technical solution of this utility model is implemented as follows: A static pressure brick forming mechanism includes a frame, a lifting platform slidably mounted on the frame, the lifting platform being driven by a main hydraulic cylinder, a lower pressing mold fixed on the bottom surface of the lifting platform, a lower cavity set on the frame below the lower pressing mold, an upper cavity set on the top surface of the lifting platform, an upper pressing mold fixed on the frame above the upper cavity, an upper distributor and a lower distributor arranged vertically on one side of the frame, the upper distributor distributing material into the upper cavity, the lower distributor distributing material into the lower cavity, and a conveying device set on one side of the frame.

[0006] Furthermore, both the upper and lower distributors are material distribution components, each including a feeding bin. One end of the feeding bin is connected to a distribution pipe, and the other end is connected to a horizontal telescopic rod. The bottom surface of the distribution pipe has a distribution port, which is located away from the horizontal telescopic rod. A feeding auger is installed inside the feeding bin. Both the upper and lower cavities include mold cavities. A baffle is installed at the end of the mold cavity away from the feeding bin. A pusher is installed at the end of the distribution pipe, which abuts against the mold cavity. The bottom surface of the distribution pipe abuts against the top surface of the mold cavity. Accurate material distribution and leveling processes result in a more uniform material distribution and density within the mold cavity, thereby improving the quality and consistency of the brick blanks.

[0007] Furthermore, an auxiliary hydraulic cylinder is provided at the bottom of the frame. The telescopic end of the auxiliary hydraulic cylinder is connected to the bottom surface of the lifting platform, and the hydraulic circuits of the main hydraulic cylinder and the auxiliary hydraulic cylinder are connected through a hydraulic synchronization valve group. The auxiliary hydraulic cylinder provides auxiliary support to the main hydraulic cylinder, sharing the load borne by the main hydraulic cylinder.

[0008] Furthermore, the ejector includes L-shaped guide plates on both sides of the distribution pipe, with the spacing between the guide plates greater than the width of the mold cavity. Each guide plate includes a horizontal section and a vertical section, connected by an arc-shaped transition section. A sealing plate and an ejector plate slide between the guide plates, hinged to each other. The sealing plate can close the distribution port. The ejector plate includes multiple connecting plates connected by hinged rods. Multiple screening holes are arrayed on each connecting plate. A drive rod corresponding to the guide plate is provided on the side wall of the distribution pipe. The drive rod moves the sealing plate along the horizontal section. When the sealing plate closes the distribution port, the ejector plate is positioned within the vertical section. By driving the movement of the sealing plate and ejector plate with the drive rod, and extending the horizontal telescopic rod, the movement of the mold cavity from the conveying device to the pressing station, and the removal of the mold cavity after pressing, are realized. This fully utilizes a horizontal telescopic rod as the driving source, reducing the number of power devices and lowering energy consumption and cost.

[0009] Furthermore, there are two sets of upper cavities and upper molds, each located on a lifting platform on either side of the main hydraulic cylinder. The material distribution component includes two parallel material distribution pipes. A V-shaped diversion supply pipe is connected to the outlet of the feed hopper, with its two branches connected to the parallel material distribution pipes. Simultaneous feeding of the two upper cavities via the V-shaped diversion supply pipe reduces waiting time and improves production continuity.

[0010] Furthermore, an electric cleaning brush is fixed to the bottom of the distribution pipe. When the push plate is placed in the vertical section, the electric cleaning brush can clean the push plate. The automated design of the electric cleaning brush improves cleaning efficiency and reduces the time and labor required for manual cleaning.

[0011] The beneficial effects of this technical solution are as follows: This utility model forms a dual-station system by cooperating the upper cavity, upper mold, lower mold, and lower cavity. While the brick blank in the lower cavity is being pressed and held under pressure, the upper cavity can simultaneously prepare for material filling, achieving parallel processing in time, reducing waiting time, and ensuring that each reciprocating movement of the main hydraulic cylinder can be effectively used to press the brick blank, thereby significantly improving production efficiency and directly reducing the production cost per unit brick blank.

[0023] 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.

[0024] like Figure 1-5 As shown, this utility model provides a static pressure brick forming mechanism, including a frame, a lifting platform 1 slidably mounted on the frame, the lifting platform 1 being driven by a main hydraulic cylinder, a lower pressing mold 2 fixed to the bottom surface of the lifting platform 1, a lower cavity 3 provided on the frame below the lower pressing mold 2, an upper cavity 4 provided on the top surface of the lifting platform 1, an upper pressing mold 5 fixed on the frame above the upper cavity 4, an upper distributor 6 and a lower distributor 7 arranged vertically on one side of the frame, the upper distributor 6 distributing material into the upper cavity 4, and the lower distributor 7 distributing material into the lower cavity 3, and a conveying device provided on one side of the frame. The conveying device can be an existing conveyor belt. The main hydraulic cylinder can be an existing double-acting hydraulic cylinder.

[0025] During the brick blank production process, the lower feeder 7 adds material to the lower cavity 3. Then, the main hydraulic cylinder extends and drives the lower die 2 on the lifting platform 1 to move to the lower cavity 3. The lower die 2 squeezes the material in the lower cavity 3 to form a brick blank. At the same time, while the lower die 2 and the lower cavity 3 are pressing the brick blank, the upper feeder 6 adds material to the upper cavity 4. After the brick blank in the lower cavity 3 is pressed, the main hydraulic cylinder drives the lifting platform 1 to move upward, so that the upper die 5 and the upper cavity 4 can press the brick blank again. At the same time as the main hydraulic cylinder returns, the conveying device sends out the lower cavity 3 and the brick blank, and conveys the new lower cavity 3 to the pressing station. Through the reciprocating movement of the lifting platform 1 and the main hydraulic cylinder, the reciprocating movement of the main hydraulic cylinder can press the brick blank. Multiple brick blanks can be processed on a single lifting platform 1 at the same time, realizing continuous pressing at two stations and improving the production capacity of the equipment.

[0026] like Figure 1-5 As shown, both the upper distributor 6 and the lower distributor 7 are material distribution components. Each material distribution component includes a feeding bin 8, one end of which is connected to a distribution pipe 9, and the other end to a horizontal telescopic rod 10. The bottom surface of the distribution pipe 9 has a distribution port 11, which is located away from the horizontal telescopic rod 10. A feeding screw 12 is located inside the feeding bin 8. Both the upper cavity 4 and the lower cavity 3 include a mold cavity. A baffle 13 is located at the end of the mold cavity away from the feeding bin 8. A pusher 14 is located at the end of the distribution pipe 9, which abuts against the mold cavity. The bottom surface of the distribution pipe 9 abuts against the top surface of the mold cavity. The feeding screw 12 and its driving method are existing technologies. The horizontal telescopic rod 10 is an existing hydraulic or pneumatic rod.

[0027] During operation, materials enter the upper cavity 4 or lower cavity 3 through the feeding bin 8 and feeding pipe 9 of the material distribution component. The material distribution component is moved by the horizontal telescopic rod 10, allowing the feeding port 11 to pass sequentially through the upper cavity 4 or lower cavity 3, accurately delivering materials into the mold cavity and ensuring accurate and consistent material distribution. When the pusher 14 abuts against the mold cavity, the horizontal telescopic rod 10 can be used to adjust the mold cavity to a designated position. The feeding pipe 9 abuts against the top surface of the mold cavity, reducing gaps between the feeding pipe 9 and the mold cavity during material distribution, preventing material overflow and waste. Furthermore, the feeding pipe 9 at the feeding port 11 can be used to level the material within the mold cavity, making it smooth and improving the quality of the brick blanks. The design of the feeding screw 12 makes feeding into the feeding pipe 9 more convenient and efficient, ensuring sufficient material in the mold cavity and preventing material shortages and production interruptions.

[0028] like Figure 1-3 As shown, the bottom end of the frame is equipped with an auxiliary hydraulic cylinder 15. The telescopic end of the auxiliary hydraulic cylinder 15 is connected to the bottom surface of the lifting platform 1. The hydraulic circuits of the main hydraulic cylinder and the auxiliary hydraulic cylinder 15 are connected through a hydraulic synchronization valve group. The hydraulic synchronization valve group is existing technology.

[0029] During brick pressing, a hydraulic synchronization valve assembly provides pressure to the main cylinder, while simultaneously providing opposite pressure to the auxiliary cylinder. The two cylinders drive in opposite directions, effectively canceling out some vibration and impact forces, resulting in smoother vertical movement of the lifting platform 1. The auxiliary cylinder 15 provides auxiliary support to the main cylinder and shares the load. For example, when the main cylinder moves the lifting platform 1 downwards, the auxiliary cylinder provides a certain pulling force, effectively reducing wear on the main cylinder and extending its service life. It also ensures more uniform pressure on the brick during forming, making it suitable for producing ultra-thick bricks. A pressure sensor dynamically adjusts the proportional valve opening to ensure synchronized operation of the main and auxiliary cylinders 15, guaranteeing that the auxiliary cylinder 15 effectively shares the load.

[0030] like Figure 4-9As shown, the ejector 14 includes L-shaped guide plates 16 disposed on both sides of the distribution pipe 9. The spacing between the guide plates 16 is greater than the width of the mold cavity. Each guide plate 16 includes a horizontal section and a vertical section, which are connected by an arc-shaped transition section. A sealing plate 17 and an ejector plate slide between the guide plates 16. The sealing plate 17 is hinged to the ejector plate and can close the distribution port 11. The ejector plate includes multiple connecting plates 18, which are connected by hinge rods 19. Multiple screening holes 20 are arrayed on each of the connecting plates 18. The side wall of the distribution pipe 9 is provided with a drive rod 21 corresponding to the guide plate 16. The drive rod 21 drives the sealing plate 17 to move along the horizontal section. When the sealing plate 17 closes the distribution port 11, the ejector plate is placed in the vertical section. The drive rod 21 is existing technology.

[0031] When the mold cavity needs to be pushed into the pressing station of the machine frame by the conveying device, the drive rod 21 moves, so that the sealing plate 17 and the push plate are both placed in the horizontal section. At this time, the raw material can enter the mold cavity through the screening hole 20. The screening hole 20 can filter the raw material during the material distribution process, improve the uniformity of the raw material, help improve the quality and consistency of the brick blank, and reduce defects caused by uneven raw material. Then, the horizontal telescopic rod 10 drives the mold cavity to move to the pressing station through the abutment of the material distribution pipe 9 and the baffle 13. After pressing is completed, the drive rod 21 drives the sealing plate 17 to close the material distribution port 11, so that the push plate is placed in the vertical section. At the same time, the push plate can abut against the end of the mold cavity near the horizontal telescopic rod 10. After the push plate slides into the vertical section, the horizontal telescopic rod 10 continues to extend, and the upper cavity 4 or lower cavity 3 is moved out of the machine frame through the push plate. The horizontal telescopic rod 10 can be used as a drive source to realize the movement and transportation of the mold cavity. The pusher 14 integrates multiple functions such as scraping, pushing and screening. Through the combination of guide plate 16, sealing plate 17 and pusher plate, it realizes the screening of raw materials and the precise movement of the mold cavity during the material distribution process.

[0032] like Figure 1-4 As shown, there are two sets of upper cavities 4 and upper molds 5, which are respectively located on the lifting platforms 1 on both sides of the main cylinder. The material distribution component includes two parallel material distribution pipes 9. A V-shaped diversion supply pipe 22 is connected to the outlet of the feed hopper 8, and the two branches of the V-shaped diversion supply pipe 22 are respectively connected to the parallel material distribution pipes 9. By setting the diversion supply pipe 22, material can be supplied to the upper cavities 4 on both sides of the main cylinder at the same time, thereby filling the upper cavities 4 on both sides of the main cylinder simultaneously, which significantly improves production efficiency.

[0033] like Figure 7As shown, an electric cleaning brush 23 is fixed to the bottom of the material distribution pipe 9. When the push plate is placed in the vertical section, the electric cleaning brush 23 can clean the push plate. The electric cleaning brush 23 is existing technology, such as an electric brush. By setting the electric cleaning brush 23, the push plate can be automatically cleaned to remove residual materials and impurities adhering to it, ensuring the cleanliness of the push plate surface and ensuring that the raw material can flow into the mold cavity evenly and smoothly when passing through the screening hole 20.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
