[0002] Refractory bricks are key components in high-temperature industrial applications such as furnaces and kilns. In existing refractory brick production processes, a tipping feeder is typically used to pour refractory brick material into the mold cavity. However, this feeding method often results in some material failing to accurately enter the mold cavity and scattering outside. This scattered material requires regular cleaning by workers, which is time-consuming, labor-intensive, and inefficient. Therefore, there is an urgent need for an improved molding device to improve the accuracy of material feeding, reduce material waste, and optimize the production process. Utility Model Content
[0003] The purpose of this invention is to provide a molding device for the production of refractory bricks, which can effectively solve the above-mentioned problems.

[0005] Includes a frame and a mold assembly, hydraulic assembly, unloading assembly, and feeding assembly mounted on the frame;
[0006] The feeding assembly includes a mounting plate mounted on the frame. A feeding frame is slidably mounted on the mounting plate via a sliding structure. A pushing cylinder is provided on one side of the feeding frame. The feeding frame is slidably mounted on the mounting plate via a sliding structure. The upper end of the feeding frame is open and located below the unloading assembly. The lower end of the feeding frame is open and has a gap with the upper surface of the mounting plate.
[0007] Furthermore, the sliding structure includes two tracks symmetrically arranged on the upper end of the mounting plate, and a movable wheel is provided in the track. The movable wheel is mounted on the front and rear end faces of the feeding frame via a rotating shaft.
[0008] Furthermore: the mold assembly includes an upper mold, a lower mold, a stripper plate, and a mold cavity disposed in the lower mold, the stripper plate forming the bottom of the mold cavity; a retaining plate is disposed on the upper end face of the lower mold, the mold cavity is located in the retaining plate, the upper end face of the retaining plate is open and flush with the upper end face of the mounting plate, and the retaining plate is also provided with a residual material recycling structure.
[0009] Furthermore: the waste material recycling structure includes a recycling plate disposed on one side of the surrounding plate, a recycling port disposed on the side of the recycling plate near the surrounding plate, a collection plate connected to the lower end of the recycling plate, a collection pipe connected to the lower end of the collection plate, and a collection box connected to the lower end of the collection pipe.
[0010] Furthermore: a scraper is provided on the lower end face of the feeding frame near the mold assembly. The scraper is made of rubber or soft plastic, and the lower end of the scraper is in contact with the upper end face of the mounting plate.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] See Figure 1-7 This is one embodiment of the molding device of this utility model for the production of refractory bricks.
[0034] like Figure 1 As shown, the device includes a frame and, mounted on the frame, a mold assembly 1, a hydraulic assembly 2, a feeding assembly 3, and a conveying assembly 4. This device significantly improves refractory brick production efficiency and reduces material waste and manual cleaning costs by optimizing the coordinated operation of material feeding, pressing, and waste material recovery. The structure, function, and collaborative workflow of each component in the refractory brick production process are described in detail below.
[0035] Structure and function of feeding assembly 4:
[0036] like Figure 3 As shown, the feeding assembly 4 includes a mounting plate 41, a push cylinder 42, and a feeding frame 44. The push cylinder 42 is fixed on the mounting plate 41, and its piston end is connected to the feeding frame 44, which can push the feeding frame 44 towards or away from the mold assembly 1 in the horizontal direction.
[0037] Meanwhile, a feeding frame 44 is slidably mounted on the mounting plate 41 via a sliding structure 43. The sliding structure 43 includes two tracks 431 symmetrically fixed to the upper end of the mounting plate 41. Each track 431 has multiple moving wheels 432 embedded in it. The moving wheels 432 are mounted on the front and rear end faces of the feeding frame 44 via a rotating shaft, so that the feeding frame 44 can slide smoothly along the track 431, reducing friction and ensuring the stability of movement.
[0038] The feeding frame 44 is a rectangular frame with openings at the top and bottom. Its upper opening is located directly below the feeding assembly 3 and is used to receive the refractory brick material conveyed by the feeding assembly 3. There is a small gap between its lower opening and the upper surface of the mounting plate 41 to ensure that the feeding frame 44 does not rub against the mounting plate 41 without affecting the conveying of refractory brick material. When the push cylinder 42 drives the feeding frame 44 to move, the feeding frame 44 accurately feeds the material into the mold cavity 14 of the mold assembly 1 through the sliding structure 43.
[0039] Structure and function of mold component 1:
[0040] like Figure 1As shown, mold assembly 1 includes an upper mold 11, a lower mold 12, a demolding template 13, a mold cavity 14, a mounting platform 15, an upper platen 16, and a lower platen 17. The mold cavity 14 is located within the lower mold 12 and is used to form refractory bricks. The demolding template 13 forms the bottom of the mold cavity 14, and demolding of the formed bricks is achieved through lifting and lowering movements. The lower mold 12 is fixed to the mounting platform 15, and a connecting plate 8 is provided on one side of the mounting platform 15. A right-angle plate 9 is integrally formed on the side of the mounting plate 41. The right-angle plate 9 is connected to the connecting plate 8 by bolts to ensure that the feeding assembly 4 and the mold assembly 1 are aligned during the feeding process, facilitating the material to be carried from the mounting plate 41 into the mold cavity 14 by the feeding frame 44.
[0041] The upper end face of the lower mold 12 is fixed with a retaining plate 5 (e.g. Figure 2 As shown), the mold cavity 14 is located in the central area of the surrounding plate 5. The upper surface of the surrounding plate 5 is open and flush with the upper surface of the mounting plate 41, so that when the feeding frame 44 slides above the surrounding plate 5, the material can fall directly into the mold cavity 14. The design of the surrounding plate 5 effectively limits the scattering of material and improves the accuracy of feeding; at the same time, it works in conjunction with the scraper 7 fixed to the lower surface of the feeding frame 44 (such as... Figure 6 As shown, when the feeding frame 44 is recycled, it can scrape the material in the entire surrounding plate 5 flat, and some of the excess material will also be carried back to the mounting plate 41 by the scraper 7, which is convenient for subsequent refractory brick pressing.
[0042] like Figure 7 As shown, the retaining plate 5 is also equipped with a residual material recovery structure 6. Although the design of the retaining plate 5 can regulate the material located at the upper end of the lower mold 12, the material above the non-mold cavity 14 will not be pressed into the mold cavity 14. This material will be enclosed in the retaining plate 5. When the feeding component 4 transports the material again, a small amount of uneven material will be pushed to the side edge of the retaining plate 5. Usually, after the feeding component 4 has transported the material four or five times, a small amount of material will overflow from the side edge of the retaining plate 5. The residual material recovery structure 6 in this application is mainly for the purpose of recovering this overflowing material.
[0043] Material capture: The recovery plate 61 is located adjacent to the side edge of the surrounding plate 5, and its upper recovery port 62 is directly aligned with the area of the surrounding plate 5 where material may overflow. The recovery port 62 has a wide opening design, which can capture the maximum amount of material overflowing from the side edge of the surrounding plate 5. The recovery plate 61 uses a smooth surface material to reduce material adhesion and facilitate the smooth flow of material into the subsequent recovery path.
[0044] Material guidance: After overflowing material enters the recovery plate 61 through the recovery port 62, it slides along the inner wall of the recovery plate 61 to the collection plate 63 connected to its lower end. The inner wall of the collection plate 63 is inclined with the front and rear ends facing the center, forming a funnel-shaped structure that gathers downwards. Gravity guides the material to flow in a concentrated manner, avoiding the material from being dispersed or blocked in the recovery path.
[0045] Material collection: The collection pipe 64 is connected to the lower end of the collecting plate 63. Its interior is a smooth pipe structure that further guides the material to the collection box 65. The collection box 65 is located at the lower end of the collection pipe 64 and is a detachable container that can be periodically removed to clean or recycle the material inside.
[0046] Coordination with feeding assembly 4: The operation of the waste material recovery structure 6 is coordinated with the operating rhythm of the feeding assembly 4. Each time the feeding frame 44 pushes the material into the surrounding plate 5, the overflowing material is captured by the recovery port 62. The entire recovery process does not require an additional driving device and relies entirely on the natural overflow and gravity flow of the material, which simplifies the structure and reduces energy consumption.
[0047] Through the above mechanism, the residual material recovery structure 6 effectively solves the problem of material overflow from the side edge of the retaining plate 5. Its working principle is based on the passive gravity recovery principle, which does not require complex mechanical drive, and has a simple structure and reliable operation.
[0048] Structure and function of hydraulic component 2:
[0049] Hydraulic assembly 2 includes a first hydraulic cylinder 21, a second hydraulic cylinder 22, and a limiting rod 23. The first hydraulic cylinder 21 drives the upper mold 11 to descend, applying pressure to press and shape the material in the mold cavity 14; the second hydraulic cylinder 22 drives the demolding plate 13 to rise, completing the demolding of the formed refractory brick. The limiting rod 23 is fixed to the frame and passes through the mounting platform 15, the upper platform 16, and the lower platform 17, assisting in the vertical lifting and lowering movement of the upper mold 11 and the demolding plate 13, ensuring the stability of the movement trajectory. The upper mold 11 is fixed to the first hydraulic cylinder 21 via the upper platform 16, and the demolding plate 13 is fixed to the second hydraulic cylinder 22 via the lower platform 17. Both the upper platform 16 and the lower platform 17 are slidably mounted on the limiting rod 23, and the sliding connection ensures the accuracy and stability of the pressing and demolding process.
[0050] Structure and function of feeding assembly 3:
[0051] The feeding assembly 3 includes a feeding hopper, which is fixed on the frame and its outlet is aligned with the upper opening of the feeding frame 44 for feeding refractory brick material into the feeding frame 44.
[0052] Work process:
[0053] 1. Material feeding: The feeding component 3 conveys the refractory brick material to the feeding frame 44 through the feeding hopper. The material passes through the feeding frame 44 and falls onto the mounting plate 41. It is restricted by the four walls of the feeding frame 44 and forms a regular material pile.
[0054] 2. Material feeding: The cylinder 42 drives the feeding frame 44 to move towards the mold assembly 1. The feeding frame 44 slides along the track 431 through the sliding structure 43, accurately feeding the material into the mold cavity 14 inside the surrounding plate 5. During the retraction process, the scraper 7 flattens the material in the surrounding plate 5, facilitating subsequent pressing.
[0055] 3. Pressing and molding: The first hydraulic cylinder 21 drives the upper mold 11 to descend along the limit rod 23, pressing the material in the mold cavity 14 under high pressure to form refractory bricks.
[0056] 4. Demolding: After pressing, the second hydraulic cylinder 22 drives the demolding plate 13 to rise along the limit rod 23, pushing the formed refractory brick out of the mold cavity 14, thus completing the demolding.
[0057] 5. Excess material recovery: Excess material scattered on the surrounding plate 5 during the feeding process enters the recovery plate 61 through the recovery port 62 of the excess material recovery structure 6, and is collected into the collection box 65 through the collection plate 63 and the collection pipe 64.
[0058] 6. Reset: Push cylinder 42 to drive mounting plate 41 to reset, feeding frame 44 returns to below unloading assembly 3, ready for the next round of feeding; upper mold 11 and stripping mold 13 also reset, entering the next production cycle.
[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
