[0019] The feasible implementations discovered in this field are as follows: Patent publication number CN110524682A discloses a static pressure molding machine for cement bricks, including a top beam, a base, an upper mold base, a lower mold base, an upper mold, a lower mold, a bottom mold, a hydraulic cylinder, a hopper, and a material trough. The top beam and the base are fixedly connected by vertically arranged guide columns. The upper mold base and the lower mold base are slidably mounted on the guide columns. The top beam and the base are respectively equipped with piston cylinders for driving the upper mold base and the lower mold base to move up and down. The upper mold is mounted on the upper mold base, and the lower mold is mounted on the lower mold base. The lower mold has a mold cavity corresponding to the upper mold. The hydraulic cylinder is mounted on the top beam, and the piston rod of the hydraulic cylinder... The mold is set downwards and abuts against the top surface of the upper mold base; the bottom mold is slidably set on the base in the horizontal direction, and a vibration power source is provided on the bottom mold; the hopper is located above and to the side of the lower mold base, the trough is located below the hopper, and the trough is slidably set between the bottom of the hopper and the top surface of the lower mold in the horizontal direction, the bottom surface of the trough is a through structure, and a scraper is provided on the side wall of the trough away from the hopper, the bottom of the trough and the scraper are in contact with the top surface of the lower mold; a quick-connect mechanism is provided between the upper mold and the upper mold base, and a drive mechanism is provided on the upper mold base for connecting and disconnecting the quick-connect mechanism; the lower mold is detachably connected to the lower mold base.

[0020] This patent utilizes a quick-connect mechanism to detachably connect the upper mold and the upper mold base, and uses a drive mechanism to connect and disconnect the quick-connect mechanism, thereby achieving automatic connection and separation of the upper mold and the upper mold base. After separation, the upper mold falls directly into the lower mold and is removed as a whole from the lower mold, reducing manual operation. In particular, when the lower mold is used in conjunction with multiple upper molds at the same time, it can greatly improve the mold changing efficiency.

[0021] Patent publication number CN220994843U discloses a static pressure molding machine for cement bricks, including a base. Multiple columns are fixedly connected to the top of the base, and a top block is fixedly connected to the top of each column. An extrusion block is slidably connected to the outside of each column, located below the top block. Multiple pressure blocks are fixedly connected to the bottom of the extrusion block. Two movable plates are symmetrically slidably connected to the outside of the columns. A vertical plate is fixedly connected to the top of each movable plate. A mold is positioned between the vertical plates. Two positioning holes are provided on both sides of the mold's surface. Two sliding rods are symmetrically slidably connected through the surface of each vertical plate. One end of each sliding rod is fixedly connected to a mounting plate. A mounting plate is also fixedly connected to one side of its surface. The fixed connection has two plug rods, one end of which is installed inside two positioning holes. Locking components are provided on the surfaces of the two vertical plates. A feeding machine is installed on one side of the base. Two first slots are symmetrically opened on the bottom of the base. Two shock-absorbing dampers are symmetrically installed on the bottom of the two first slots. A bearing plate is provided on the top of the base. A second slot is provided on the bottom of the bearing plate. The output ends of the two shock-absorbing dampers are fixedly connected to the bottom of the second slot.

Springs are installed on the outside of the two shock-absorbing dampers. The two ends of the springs are fixedly connected to the bottom of the sliding plate and the bottom of the first slot, respectively.

[0022] This patented design incorporates a sliding rod, screw, and insert rod. The screw's rotation drives the insert rod on one side of the mounting plate to install inside the positioning hole of the mold, enabling rapid installation of molds of different sizes. This solves the problem of low efficiency associated with traditional bolt-mounted installations, thus improving the efficiency and practicality of the cement brick static pressure molding machine. Furthermore, the patent utilizes a bearing plate with shock absorption damping, springs, and a sliding plate. During static pressure molding of cement bricks, the impact force on the bearing plate is buffered by the damping and springs, reducing vibration and extending the machine's service life, further enhancing its practicality.

[0023] Patent publication number CN110587784A discloses a method for static pressing of cement bricks. The method involves changing the mold of a static pressing machine for cement bricks according to the design specifications of the cement bricks and adjusting the filling height of the mold. The static pressing machine includes a top beam, a base, an upper mold base, a lower mold base, an upper mold, a lower mold, a bottom mold, a hydraulic cylinder, a hopper, and a material trough. The top beam and base are fixedly connected by vertically arranged guide columns. The upper mold base and lower mold base are slidably mounted on the guide columns. The top beam and base are respectively equipped with piston cylinders for driving the upper and lower mold bases to move up and down. The upper mold is mounted on the upper mold base, and the lower mold is mounted on the lower mold base. The lower mold has a cavity corresponding to the upper mold. The hydraulic cylinder is mounted on the top beam. The piston rod is positioned downwards and abuts against the top surface of the upper mold base; the bottom mold is slidably mounted on the base in the horizontal direction, and a vibration power source is provided on the bottom mold; the hopper is located above and to the side of the lower mold base, and the trough is located below the hopper, and is slidably mounted in the horizontal direction between the bottom of the hopper and the top surface of the lower mold. The bottom surface of the trough has a through-type structure, and a scraper is provided on the side wall of the trough away from the hopper. The bottom of the trough and the scraper are in contact with the top surface of the lower mold; a quick-connect mechanism is provided between the upper mold and the upper mold base, and a drive mechanism is provided on the upper mold base for connecting and disconnecting the quick-connect mechanism; the lower mold is detachably connected to the lower mold base; the bottom mold has pads corresponding to the mold cavities, and the pads are movably mounted in the vertical direction. The bottom mold has a height adjustment mechanism for adjusting the height of the pads. Adjustment mechanism; The specific method for changing the mold is as follows: Close the upper mold base and lower mold base, insert the upper mold into the bottom of the mold cavity, drive the quick-connect mechanism to disengage, causing the upper mold to fall into the mold cavity, then separate the upper mold plate and lower mold plate, and remove the lower mold from the lower mold plate; Place the new upper mold into the new lower mold cavity, install the new lower mold on the lower mold base, close the upper mold base and lower mold base again, drive the quick-connect mechanism between the upper mold base and the new upper mold to connect, and finally control the upper mold base and lower mold base to separate, completing the mold replacement; The specific method for adjusting the filler height is as follows: The height adjustment mechanism adjusts the height of the pad according to the required filler height before compaction of the cement brick to change the height of the material that the mold cavity can accommodate; Static pressing molding of cement bricks After the machine is debugged, cement material is fed into the hopper, which quantitatively adds cement material into the feed trough. This process uses overfeeding, meaning the amount of material added is greater than the amount required for cement brick forming. The feed trough transfers the cement material to the top of the lower mold, where it fills the mold cavity. During this process, the vibration power source of the bottom mold continuously vibrates the lower mold to compact the cement material. After the cement material fills the mold cavity, the feed trough moves in the opposite direction, and the scraper scrapes the excess material at the top of the mold cavity. Then, the adjustment mechanism adjusts the pad to the lowest point, and the upper mold plate moves down to pre-compress the filler. When the filling forming height is 3-5mm higher than the designed height of the cement brick, the hydraulic cylinder begins to pressurize the upper mold base until the forming height reaches the designed height of the cement brick.Finally, the hydraulic cylinder releases pressure, and the upper and lower mold bases move upwards synchronously for a short distance, moving the bottom mold out of the space below the lower mold base. Then, the upper and lower mold bases move downwards synchronously, bringing the bottom surface of the lower mold close to the receiving plate at the bottom of the molding machine. The lower mold base is then driven upwards while maintaining the height of the upper mold base. The brick blank inside the mold cavity falls from the bottom of the cavity onto the receiving plate under the obstruction of the upper mold, completing the molding process.

[0024] This patent utilizes a quick-connect mechanism to detachably connect the upper mold and the upper mold base, and uses a drive mechanism to connect and disconnect the quick-connect mechanism, realizing the automatic connection and separation of the upper mold and the upper mold base. After separation, the upper mold falls directly into the lower mold and is removed as a whole, reducing manual operation. In particular, when the lower mold is used with multiple upper molds at the same time, it can greatly improve the mold changing efficiency. In addition, this patent does not require mold replacement when processing bricks of the same shape but different thicknesses, further improving the operating efficiency of the equipment.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1 to 5 This invention provides a static pressure molding machine for cement bricks, including a base 1. A top seat 2 is fixedly connected to the top surface of the base 1 by a plurality of guide columns 11. An upper mold assembly and a lower mold assembly are arranged between the base 1 and the top seat 2. The upper mold assembly and the lower mold assembly move along the guide columns 11. The upper mold assembly is arranged above the lower mold assembly, and a conveyor belt 5 is arranged below the lower mold assembly. A plurality of base plates are arranged on the conveyor belt 5, and the base plates are detachably connected to the lower mold assembly. Both the upper mold assembly and the lower mold assembly are equipped with clamping components. The clamping components of the upper mold assembly are used to clamp the upper template 31, and the clamping components of the lower mold assembly are used to clamp the lower template 41.

[0028] When the base plate is below the lower mold assembly, a first hydraulic press 12 is installed below the base plate. The fixed end of the first hydraulic press 12 is fixedly connected to the base 1, and the telescopic end of the first hydraulic press 12 abuts against the base plate through a connecting plate to provide stable support for the base plate. The area of ​​the connecting plate is smaller than the area of ​​the base plate but larger than the cross-sectional area of ​​the telescopic end of the first hydraulic press 12. Then, the lower mold assembly descends, so that the lower template 41 is on the base plate, and then the feeding machine feeds material into the lower template 41.

[0029] This invention uses the clamping component of the upper mold assembly to clamp the upper template 31 and the clamping component of the lower mold assembly to clamp the lower template 41, thus avoiding the time required for installing and removing multiple bolts. This effectively makes the installation and removal of the lower template 41 and the upper template 31 quick and convenient, and effectively improves production efficiency.

[0030] The design was further optimized by setting multiple guide pillars 11 at equal intervals. These guide pillars 11 are then evenly spaced between the base 1 and the top seat 2.

[0031] Further optimization of the scheme: the upper mold assembly includes a first movable plate 3, the end of the first movable plate 3 facing the top seat 2 is fixedly connected to the telescopic end of the third hydraulic press 21, and the fixed end of the third hydraulic press 21 is fixedly connected to the top surface of the top seat 2.

[0032] The first moving plate 3 is moved along the guide column 11 by the third hydraulic press 21.

[0033] Further optimization of the scheme: the lower mold assembly includes a second movable plate 4, and a second hydraulic press 13 is symmetrically arranged on one end of the second movable plate 4 facing the base 1. The fixed end of the second hydraulic press 13 is fixedly connected to the base 1, and the telescopic end of the second hydraulic press 13 is fixedly connected to the second movable plate 4.

[0034] The second hydraulic press 13 drives the second moving plate 4 to move along the guide column 11.

[0035] To further optimize the design, two second hydraulic presses 13 are positioned on either side of the conveyor belt 5. This allows the two second hydraulic presses 13 to stably drive the second moving plate 4 along the guide column 11.

[0036] In a further optimized design, the first movable plate 3 is positioned above the second movable plate 4, and both the first movable plate 3 and the second movable plate 4 are slidably connected to the guide post 11.

[0037] Further optimization of the scheme: the clamping component includes grooves 32 formed on the first moving plate 3 and the second moving plate 4. Slide grooves 34 are formed on any two opposite inner walls of the grooves 32. U-shaped plates 36 are symmetrically arranged between the two slide grooves 34. Limiting grooves 37 are formed at opposite ends of the two U-shaped plates 36. The two limiting grooves 37 are detachably connected to the support plate 42.

[0038] The support plate 42 has a through hole in the middle, and the upper template 31 is fixedly connected to the through hole of the support plate 42 located in the upper mold assembly; the lower template 41 is fixedly connected to the through hole of the support plate 42 located in the lower mold assembly.

[0039] By ensuring that the cross-sectional area of ​​the support plate 42 is greater than that of the upper template 31 or the lower template 41, the limiting grooves 37 of the two U-shaped plates 36 can effectively clamp the support plate 42.

[0040] The U-shaped plate 36 is arranged in a U-shape so that the three sides and two corners of the support plate 42 can be stably inserted into the limiting groove 37 on the U-shaped plate 36.

[0041] Since there are multiple templates of different specifications, but the specifications of the support plate 42 remain unchanged, by fixing the templates of different specifications into the through holes on different support plates 42, the U-shaped plate 36 only needs to clamp one type of support plate 42.

[0042] In a further optimized design, sliders 35 are fixedly connected to both ends of the U-shaped plate 36. The sliders 35 are slidably connected to the slide groove 34. One end of the slider 35 that extends into the slide groove 34 is threadedly connected to a lead screw 33. One end of the lead screw 33 is rotatably connected to the slide groove 34. The other end of the lead screw 33 is driven to the output shaft of a motor 38. The motor 38 is fixedly connected in the groove 32.

[0043] The lead screw 33 is a bidirectional lead screw, and the two sliders 35 on the lead screw 33 can move closer or further away from each other synchronously.

[0044] The motor 38 drives the lead screw 33 to rotate, and the lead screw 33 drives the two sliders 35 to move closer or further apart. The two sliders 35 can synchronously drive the two U-shaped plates 36 to move closer or further apart. When the two U-shaped plates 36 move further apart, it is convenient to disassemble the upper template 31 and the lower template 41. When the two U-shaped plates 36 move closer together, they can effectively clamp the upper template 31 and the lower template 41.

[0045] In a further optimized design, the groove 32 on the first moving plate 3 does not penetrate the first moving plate 3 and is opened towards the second moving plate 4. This allows the end of the first moving plate 3 facing away from the groove 32 to be effectively fixedly connected to the telescopic end of the third hydraulic press 21.

[0046] In a further optimized design, a groove 32 is formed on the second movable plate 4, penetrating through the second movable plate 4. Through the groove 32 formed on the second movable plate 4, the upper template 31 can penetrate the groove 32 on the second movable plate 4 and extend into the lower template 41.

[0047] Working process: According to the specifications of the cement bricks to be made, select the matching upper template 31 and lower template 41. Then, the motor 38 drives the lead screw 33 to rotate, and the lead screw 33 drives the two sliders 35 to move away from each other. The two sliders 35 can synchronously drive the two U-shaped plates 36 to move away from each other. When the two U-shaped plates 36 move away from each other, it is easy to disassemble the original upper template 31 and lower template 41, and place the required upper template 31 and lower template 41 between the two U-shaped plates 36. Then, the motor 38 drives the lead screw 33 to rotate, so that the two U-shaped plates 36 move closer to each other. When both ends of the upper template 31 and lower template 41 are inserted into the limiting groove 37, the two U-shaped plates 36 can effectively clamp the upper template 31 and lower template 41.

[0048] That is, the upper template 31 and the lower template 41 are replaced in sequence according to the above steps.

[0049] Then, the conveyor belt 5 starts, conveying multiple base plates. When any base plate is below the lower mold assembly, the conveyor belt 5 stops conveying. At this time, the telescopic end of the first hydraulic press 12 extends and abuts against the base plate through the connecting plate, providing stable support for the base plate. Then, the telescopic end of the second hydraulic press 13 retracts, causing the lower mold assembly to descend and the lower mold plate 41 to be on the base plate. Then, the feeding machine feeds material into the lower mold plate 41. After feeding is completed, the third hydraulic press 21 drives the upper mold plate 31 to move into the lower mold plate 41. When the upper mold plate 31 passes through the groove 32 on the second moving plate 4 and extends into the lower mold plate 41, the upper mold plate 31 squeezes the raw material in the lower mold plate 41. After squeezing is completed, the lower mold plate 41 rises. Then, the upper mold plate 31 demolds the cement brick formed in the lower mold plate 41. After demolding is completed, the upper mold plate 31 rises, and then the conveyor belt 5 starts, so that the next empty base plate is below the lower mold assembly, and continuous operation can be carried out.
