Description

Technical Field

[0001] This utility model relates to the technical field of refractory brick production molding equipment, specifically a molding device for refractory brick production. Background Technology

[0002] Refractory bricks, also known as fire bricks, are refractory material products made from refractory clay or other refractory raw materials. They usually have a certain shape and size and can maintain stable physical and chemical properties in high-temperature environments. As the market demand for refractory bricks increases, molding devices for refractory brick production are often used to ensure the mass production of refractory bricks, which increases production efficiency while ensuring the quality of refractory bricks.

[0003] In existing refractory brick production molding devices, operators need to hold a metering container and pour the mixed raw materials one by one into the pressing chamber. Then, a hydraulic cylinder drives the pressing plate to move downward to press the raw materials inside the pressing chamber. Finally, by controlling the cylinder, the cylinder will drive the push plate to push the pressed refractory brick out of the pressing chamber. The workers will then take out the pushed refractory brick and place it on a tray.

[0004] Existing molding devices for refractory brick production require manual pouring of raw materials one by one. Each operation takes time to complete actions such as material retrieval, movement, and pouring. Especially during mass production, frequent repetitive operations significantly extend the production cycle. Furthermore, when using cylinders to eject the molded refractory bricks, pressure fluctuations in the air supply system can directly lead to unstable ejection force from the cylinders. This may result in the refractory bricks not being ejected smoothly, causing mold jamming, or excessive ejection force that impacts the refractory bricks, leading to cracks or damage and affecting product quality. Therefore, we propose a molding device for refractory brick production. Utility Model Content

[0008] Furthermore, a microcontroller is provided on the left side of the chassis. The input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0009] Furthermore, the automatic loading and unloading mechanism also includes a worm wheel and a worm. The worm wheel is fixedly sleeved on the outside of the rotating rod, and the worm is rotatably connected between the left and right inner walls of the machine box. The worm wheel and the worm are meshed together to achieve stable ejection.

[0010] Furthermore, the feeding assembly includes a U-shaped frame, a slider, a storage box, a guide rod, and a lead screw. The U-shaped frame is located on the upper surface of the machine housing. A slider is slidably connected inside the U-shaped frame, and a storage box is located between two sliders. The storage box is installed in conjunction with the pressing chamber. A guide rod is located at the right end of the rear inner wall of the U-shaped frame, and the middle part of the slider on the right side is slidably connected to the guide rod.

[0011] Furthermore, the feeding assembly also includes a right-angle motor, which is located at the rear left end of the U-shaped frame. The front end of the output shaft of the right-angle motor is fixedly connected to the rear end of the lead screw, and the input end of the right-angle motor is electrically connected to the output end of the microcontroller to provide feeding drive.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The molding device for producing refractory bricks has the following advantages:

[0015] 1. The screw is driven by a right-angle motor to rotate, causing the storage box to slide inside the U-shaped frame under the guidance and limit of the guide rod. When it passes the top of the pressing chamber, the raw material falls into the pressing chamber under the action of gravity, thus feeding the pressing chamber. The feeding process can be completed in a short time. Compared with manual handling and pouring of materials, it saves a lot of time and helps to improve the rhythm of the entire production process.

[0016] 2. The motor drives the worm gear to rotate, which in turn drives the rotating rod to rotate. This causes the connecting rod to move the push rod, which in turn pushes the support plate under the guidance of the sliding rod, causing the push block to slide upward inside the pressing chamber. This process ejects the pressed refractory bricks, ensuring stable ejection and avoiding impacts on the bricks. This prevents defects such as cracks, chipping, or breakage, reducing production interruptions and defect rates caused by ejection problems. The overall production process is smoother, which helps improve the production efficiency and output of refractory bricks. Attached Figure Description

Rotating rods 64 are rotatably connected between the front and rear inner walls of the machine housing 1. Connecting rods 65 are fixedly sleeved on the outer side of rotating rods 64. Top rods 66 are rotatably connected to the top ends of connecting rods 65. The top ends of top rods 66 are rotatably connected to the front and rear sides of support plate 62. Feeding assembly 69 is set on the upper surface of machine housing 1. Automatic loading and unloading mechanism 6 also includes The worm gear 67 and worm 68 are fixedly sleeved on the outside of the rotating rod 64. The worm 68 is rotatably connected between the left and right inner walls of the housing 1. The worm gear 67 and worm 68 are meshed together (the worm gear 67 and worm 68 are both located inside the protective cover set on the bottom wall of the housing 1. The outer side of the protective cover has clearance holes corresponding to the worm 68 and rotating rod 64. The outer sides of the worm 68 and rotating rod 64 are respectively connected to the inner wall of the clearance holes through sealed bearings to prevent floating dust from affecting the meshing of the worm gear 67 and worm 68). The feeding assembly 69 includes a U-shaped frame 691, a slider 692, a storage box 693, a guide rod 694, and a lead screw 695. The U-shaped frame 691 is set on the upper surface of the housing 1. The slider 692 is slidably connected inside the U-shaped frame 691. A storage bin 693 is provided between 692 (the left slider 692 is fixedly connected to the left side of the storage bin 693 via an N-shaped frame to prevent raw materials from clogging the lead screw 695 and affecting transmission during long-term use). The storage bin 693 is installed in conjunction with the pressing chamber 5 (the bottom of the storage bin 693 is not equipped with a baffle; when passing through the pressing chamber 5, the raw materials inside will flow into the interior of the pressing chamber 5). A guide rod 694 is provided on the right end of the rear inner wall of the U-shaped frame 691. The middle part of the right slider 692 is slidably connected to the guide rod 694. The left end of the rear inner wall of the U-shaped frame 691 is rotatably connected to the lead screw 695. The middle part of the left slider 692 is threadedly connected to the lead screw 695. The feeding assembly 69 also includes a right-angle motor 696, which is located on the U-shaped frame 691. At the rear left end, the front end of the output shaft of the right-angle motor 696 is fixedly connected to the rear end of the lead screw 695. The input end of the right-angle motor 696 is electrically connected to the output end of the microcontroller 9. A motor 7 is located on the left side of the chassis 1. The right end of the output shaft of the motor 7 is fixedly connected to the left end of the worm gear 68. The input end of the motor 7 is electrically connected to the output end of the microcontroller 9. Then, the mixed refractory brick raw materials are poured into the storage box 693. Through the control of the microcontroller 9, the right-angle motor 696 starts to run, and the output shaft drives the lead screw 695 to start rotating. This causes the slider 692 on the right side of the storage box 693 to slide inside the U-shaped frame 691 under the limit of the guide rod 694. When the storage box 693 passes the upper end of the pressing chamber 5, since there is no baffle at the bottom of the storage box 693,The raw materials inside flow into the pressing chamber 5 under gravity. Then, the right-angle motor 696 reverses its direction, causing the storage bin 693 to return to its original position. Through the control of the microcontroller 9, the motor 7 starts running, and its output shaft drives the worm gear 68 to rotate. This causes the meshing worm wheel 67 to drive the rotating rod 64 to rotate. The rotating rod 64 drives the externally fixed connecting rod 65 to rotate. When the connecting rod 65 rotates, it pushes the top rod 66, which is rotatably connected at the top, upwards. The top rod 66 pushes the support plate 62, causing the top block 63 on the upper surface to slide inside the pressing chamber 5 under the guidance of the slide rod 61, thus ejecting the pressed refractory bricks. This process is repeated. When the storage bin 693 is feeding raw materials into the pressing chamber 5, the front side of the storage bin 693 pushes the pressed refractory bricks forward.

[0024] The working principle of the molding device for refractory brick production provided by this utility model is as follows: When the molding device is needed in the production of refractory bricks, the machine box 1 is first placed in a suitable position, and then the mixed refractory brick raw materials are poured into the storage box 693. Through the control of the single-chip microcomputer 9, the right-angle motor 696 starts to run, and the output shaft drives the lead screw 695 to start rotating, so that the slider 692 on the right side of the storage box 693 slides inside the U-shaped frame 691 under the limit of the guide rod 694. When the storage box 693 passes the upper end of the pressing chamber 5, since there is no baffle at the bottom of the storage box 693, the raw materials inside will flow into the pressing chamber 5 under the action of gravity. Then the right-angle motor 696 drives in the reverse direction to make the storage box 693 return to its original position. The hydraulic oil is pressurized by the hydraulic pump, and then the high-pressure oil is delivered. The material is fed into the hydraulic cylinder 8, which in turn pushes the support plate 3 to drive the pressure block 4 into the pressing chamber 5 under the guidance of the support rod 2, pressing the material inside. Under the control of the microcontroller 9, the motor 7 starts to run, and the output shaft drives the worm gear 68 to start rotating, so that the meshing worm wheel 67 drives the rotating rod 64 to start rotating. The rotating rod 64 drives the externally fixed connecting rod 65 to rotate. When the connecting rod 65 rotates, it pushes the top rod 66, which is rotatably connected at the top, to move upward. The top rod 66 pushes the support plate 62 to drive the top block 63 on the upper surface to slide inside the pressing chamber 5 under the guidance of the slide rod 61, pushing out the pressed refractory brick. The above operation is repeated. When the storage box 693 is conveying raw materials into the pressing chamber 5, the front side of the storage box 693 will push the pressed refractory brick forward.

[0025] It is worth noting that the microcontroller 9 disclosed in the above embodiments can be an STM32F103C8, the motor 7 can be a YS8024, and the right-angle motor 696 can be a RAX-271E. The microcontroller 9 controls the operation of the motor 7 and the right-angle motor 696 using methods commonly used in the prior art.
