Description

Technical Field

[0001] This application relates to the field of processing sand cores for water outlet pipes, and more specifically, to a rapid curing device and curing method for sand cores for water outlet pipes. Background Technology

[0002] A rapid curing device and method for sand cores in water outlet pipes. The curing heating is a process that promotes chemical cross-linking of materials by heating. In the field of electrical engineering, it is mainly used in the preparation of insulating materials, electronic packaging and composite materials.

[0003] The structure of the product can be referenced from a sand core curing device disclosed in Chinese Patent Document 202322751104.3, which includes a box assembly. The box assembly includes: a base with a baking oven fixedly connected to its top; a placement tray disposed on the bottom surface inside the baking oven; and a sand core body disposed on the top of the placement tray. A curing component is disposed inside the baking oven. This utility model has the advantages of multi-directional drying and convenient adjustment. During use, hot air acts on the sand core body through multiple holes to achieve horizontal ventilation baking. Some hot air is discharged through multiple through holes at the bottom of the shell to achieve vertical ventilation baking. The telescopic shell completely covers the holes above the sand core body, avoiding resource waste. It improves curing efficiency through multi-directional air supply baking and avoids direct contact between hot air and the sand core body, improving resource utilization. It solves the problem that existing sand core molding heating and curing devices do not have good adjustment functions.

[0004] Sand cores require heat curing during processing, which significantly improves their physical properties. Heated sand cores exhibit higher strength, density uniformity, and dimensional stability. For example, in coated sand processes, this ensures the outer layer of the sand core is fully cured while retaining some loose sand internally, balancing strength and permeability, and preventing deformation or cracking during casting. However, in this patent, because the entire core is fixed, the curing efficiency is relatively low.

[0005] A rapid curing device and curing method for sand cores in water outlet pipes are now provided. Summary of the Invention

[0006] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide a rapid curing device and method for sand cores in water outlet pipes, comprising: a housing; four support rods fixedly connected to the four bottom corners of the housing; a feed inlet on the side plate of the housing; a conveying hopper slidably disposed on the side plate of the housing, the bottom of the conveying hopper being inclined and corresponding to the feed inlet; and a lifting assembly disposed on the housing for lifting the conveying hopper. The discharge port is located on the side panel of the housing; there are two connecting blocks, one of which is fixed to the side panel of the housing, and the other is slidably mounted on the side panel of the housing, with a flexible mesh fixed between the two connecting blocks; a slider is fixed to the connecting block; a sliding groove is located on the side panel of the housing, and the slider and the sliding groove are slidably mounted; a fixing groove is located on the slider; a fixing component is located on the housing for fixing the slider and corresponds to the top wall of the sliding groove; a cylinder is located inside the housing and below the flexible mesh, with a movable seat fixed to the bottom of the cylinder; and a top ball is located on the cylinder. A first lead screw is rotatably mounted between two side plates of the housing and threadedly connected to a movable seat; a servo motor is fixedly connected to the first lead screw, and the output shaft of the servo motor is fixedly connected to the first lead screw; a heater is fixedly connected to the top plate of the housing, and the heater's air outlet pipe is a flexible hose, with an opening on the top plate of the housing through which the heater's air outlet pipe passes; a connecting cylinder is disposed inside the housing, and multiple air outlet holes are evenly distributed on the connecting cylinder; a connecting piece is disposed between the connecting cylinder and the heater's air outlet pipe; and a moving assembly is disposed on the housing for moving the connecting cylinder back and forth.

[0008] Before the sand core needs to be cured and heated, it can first be placed into the conveyor hopper. Then, the servo motor can be started. When the servo motor starts, the output shaft of the servo motor drives the first lead screw to rotate. Under the action of the first driving bevel gear and the first driven bevel gear meshing, the rotating rod rotates. Under the action of the second driving bevel gear and the second driven bevel gear meshing, the second lead screw rotates. Under the action of the second limit rod, the conveyor hopper rises. When the conveyor hopper rises to correspond with the feed inlet, due to the inclined bottom of the conveyor hopper, the sand core in the conveyor hopper falls into the feed inlet under the action of gravity and then enters the soft mesh, which facilitates feeding and saves labor.

[0009] Next, the sand core is heated and cured. The heater can be activated, allowing hot air to enter the connecting cylinder through the first and second connecting pipes, and then be discharged through the air outlet. This process heats and cures the sand core on the soft mesh. The cylinder can also be activated, causing the output shaft of the cylinder to drive the top ball to move up and down repeatedly. When the top ball rises, because the soft mesh is a deformable mesh material, the rising top ball pushes the soft mesh, causing the lower sand core to flip to the top, and the previously upper sand core to flip to the bottom. This back-and-forth movement initially improves the heating efficiency. At the same time, when the servo motor is activated, the output shaft of the servo motor drives the first lead screw to rotate, causing the moving seat to move back and forth, ensuring that the top ball lifts every part of the soft mesh, further improving the heating efficiency.

[0010] Simultaneously, when the first lead screw rotates, the third lead screw rotates back and forth under the action of the pulley and belt, causing the connecting seat to move back and forth. Since the heater's air outlet pipe is a flexible hose, the connecting seat drives the connecting cylinder to move back and forth to release air, thereby further improving the heating efficiency. Furthermore, under the action of the first gear and rack, when the second connecting pipe moves back and forth, it causes the second connecting pipe to rotate back and forth, thereby causing the connecting cylinder to rotate back and forth, further improving the heating efficiency.

[0011] After the curing and heating process is complete, the pull ring can be pulled to disengage the fixing rod from the fixing groove. At this point, the slider is no longer restrained, and the connecting block falls into the bottom wall of the chute under the action of gravity. The soft mesh is straightened and tilted at this time, and the connecting block is flush with the bottom wall of the discharge port. This allows the sand core to be automatically discharged under the action of gravity, improving the discharge efficiency and saving effort. After the discharge is complete, the handle can be moved to allow the slider to slide to the top wall of the chute. At this point, the fixing rod corresponds to the fixing groove, and under the action of the fixing spring, the fixing rod 42 is stably inserted into the fixing groove, which also facilitates disassembly.

[0012] In some embodiments, the lifting assembly includes a second lead screw, both ends of the conveying bucket are fixedly connected to conveying plates, and two sets of fixed seats are fixedly connected to the side plate of the box, with two seats in each set. The second lead screw is rotatably installed between two of the fixed seats, and a first linkage assembly is provided between the second lead screw and the first lead screw. A second limiting rod is fixedly connected between the other two fixed seats. The second limiting rod passes through the conveying plate and is slidably installed with the conveying plate.

[0013] In some implementations, the first linkage component includes a first driving bevel gear, a first driven bevel gear, a second driving bevel gear, and a second driven bevel gear. A rotating seat is fixedly connected to the side plate of the housing, and a rotating rod is rotatably mounted on the rotating seat. The first driving bevel gear is fixedly connected to a first lead screw, and the first driven bevel gear is fixedly connected to the rotating rod. The first driving bevel gear meshes with the first driven bevel gear. A second driving bevel gear is fixedly connected to the other end of the rotating rod, and the second driven bevel gear is fixedly connected to a second lead screw. The second driving bevel gear meshes with the second driven bevel gear.

[0014] In some embodiments, the fixing assembly includes a fixing rod slidably mounted on the inner wall of the slide groove and corresponding to the fixing groove. A mounting bracket is fixedly connected to the side plate of the housing. The fixing rod passes through the mounting bracket and is slidably mounted to the mounting bracket. A connecting ring is fixedly connected to the fixing rod. A fixing spring is sleeved on the fixing rod and fixed between the connecting ring and the mounting bracket. A pull ring is fixedly connected to the fixing rod. A handle is fixedly connected to the slider.

[0015] In some embodiments, the movable component includes a connecting seat that is slidably mounted between two side plates of the housing, a third lead screw that is rotatably mounted between the two side plates of the housing, the third lead screw being threadedly connected to the connecting seat, and a linkage component being provided between the third lead screw and the first lead screw.

[0016] In some embodiments, the linkage assembly includes two pulleys and a belt, with the two pulleys respectively fixed to a first lead screw and a third lead screw, and the belt drive installed between the two pulleys.

[0017] In some implementations, the connecting element includes a first connecting pipe and a second connecting pipe. The first connecting pipe is connected to the air outlet pipe of the heater and is fixedly connected to the connecting seat. The second connecting pipe is rotatably connected to and communicates with the first linkage pipe and is rotatably mounted on the movable seat. The housing is provided with a rotating component.

[0018] In some embodiments, the rotating assembly includes a gear and a rack, the rack being fixed between two side plates of the housing, the gear being fixed to a second connecting pipe, and the gear meshing with the rack.

[0019] In some embodiments, a limiting strip is fixed between the two side panels of the housing, the limiting strip passes through the movable seat and slides with the movable seat, and a limiting post is fixed between the two side panels of the housing, the limiting post passes through the connecting seat and slides with the connecting seat.

[0020] In some implementations, step 1 involves placing the sand core into the conveying hopper. Then, the servo motor is started. When the servo motor starts, its output shaft drives the first lead screw to rotate. Under the meshing of the first driving bevel gear and the first driven bevel gear, the rotating rod rotates. Under the meshing of the second driving bevel gear and the second driven bevel gear, the second lead screw rotates. Under the action of the second limiting rod, the conveying hopper rises. When the conveying hopper rises to correspond with the feed inlet, due to the inclined bottom of the conveying hopper, the sand core inside falls into the feed inlet under gravity and then enters the flexible mesh, thus facilitating feeding and saving labor.

[0021] Step 2: The heater can be activated, allowing hot air to enter the connecting cylinder through the first and second connecting pipes, and then be discharged through the air outlet, thereby heating and curing the sand core on the soft mesh. The cylinder can also be activated, and the output shaft of the cylinder drives the top ball to rise and fall repeatedly. When the top ball rises, because the soft mesh is a deformable mesh material, the top ball pushes the soft mesh, causing the sand core at the bottom to flip to the top, and the sand core at the top to flip to the bottom, flipping back and forth. At the same time, when the servo motor is activated, the output shaft of the servo motor drives the first lead screw to rotate, causing the moving seat to move back and forth, so that the top ball lifts every part of the soft mesh.

[0022] Step 3: When the first lead screw rotates, the third lead screw rotates back and forth under the action of the pulley and belt, which in turn causes the connecting seat to move back and forth. Since the air outlet pipe of the heater is a flexible hose, the connecting seat drives the connecting cylinder to move back and forth to release air. Furthermore, under the action of the first gear and rack, when the second connecting pipe moves back and forth, it causes the second connecting pipe to rotate back and forth, which in turn causes the connecting cylinder to rotate back and forth, thereby further improving the heating efficiency.

[0023] Step 4: After the curing and heating are complete, pull the ring to disengage the fixing rod from the fixing groove. At this time, the slider is no longer restrained, and the connecting block falls into the bottom wall of the chute under the action of gravity. The soft mesh is straightened and tilted. The connecting block is flush with the bottom wall of the discharge port, so that the sand core is automatically discharged under the action of gravity, which improves the discharge efficiency and saves more effort.

[0024] Step 5: After the material is discharged, the handle can be moved so that the slider slides to the top wall of the groove. At this time, the fixing rod corresponds to the fixing groove. Under the action of the fixing spring, the fixing rod is stably inserted into the fixing groove, and heating and curing can continue.

[0025] The beneficial effects of this application are as follows: By setting up a soft net and a top ball, when the top ball rises, the soft net, being a deformable mesh material, pushes against it, causing the sand core below to flip to the top, while the sand core above flips to the bottom, and so on. Simultaneously, when the servo motor starts, its output shaft drives the first lead screw to rotate, causing the moving seat to move back and forth, so that the top ball lifts up every part of the soft net.

[0026] By setting up a first gear and rack, when the second connecting pipe moves back and forth, it causes the second connecting pipe to rotate back and forth, which in turn causes the connecting cylinder to rotate back and forth, thereby further improving the heating efficiency.

[0027] By setting up a conveyor bucket and a second lead screw, when the servo motor starts, the output shaft of the servo motor drives the first lead screw to rotate. Under the action of the meshing of the first driving bevel gear and the first driven bevel gear, the rotating rod rotates. Under the action of the meshing of the second driving bevel gear and the second driven bevel gear, the second lead screw rotates. Under the action of the second limit rod, the conveyor bucket rises. When the conveyor bucket rises to correspond with the feed inlet, due to the inclined bottom of the conveyor bucket, the sand core in the conveyor bucket falls into the feed inlet under the action of gravity, and then enters the soft mesh, thus facilitating material feeding and saving labor.

[0028] By setting up a first connecting pipe, a second connecting pipe, a movable seat, a belt, and a pulley, the third lead screw rotates back and forth under the action of the pulley and the belt, thereby causing the connecting seat to move back and forth. Since the air outlet pipe of the heater is a flexible hose, the connecting seat drives the connecting cylinder to move back and forth to release air. Furthermore, under the action of the first gear and rack, when the second connecting pipe moves back and forth, it causes the second connecting pipe to rotate back and forth, causing the connecting cylinder to rotate back and forth, thereby further improving the heating efficiency.

By setting the limiting strip 24, the stability of the movable base 14 is improved, and by setting the limiting post 11, the stability of the connecting base 15 is further improved.

[0047] Working process: Before the sand core needs to be cured and heated, the sand core can first be placed into the conveying hopper 19. Then, the servo motor 17 can be started. When the servo motor 17 is started, the output shaft of the servo motor 17 drives the first lead screw 25 to rotate. Under the action of the first driving bevel gear 37 and the first driven bevel gear 36 meshing, the rotating rod 16 rotates. Under the action of the second driving bevel gear 33 and the second driven bevel gear 32 meshing, the second lead screw 3 rotates. Under the action of the second limit rod 2, the conveying hopper 19 rises. When the conveying hopper 19 rises to correspond with the feed port 23, due to the inclined bottom of the conveying hopper 19, the sand core in the conveying hopper 19 falls into the feed port 23 under the action of gravity, and then enters the soft mesh 8, which facilitates feeding and saves labor.

[0048] Next, the sand core is heated and cured. The heater 7 can be activated, allowing hot air to enter the connecting cylinder 20 through the first connecting pipe 28 and the second connecting pipe 31, and then be discharged through the air outlet 21, thereby heating and curing the sand core on the soft mesh 8. The cylinder 12 can also be activated, causing the output shaft of the cylinder 12 to drive the top ball 9 to rise and fall repeatedly. When the top ball 9 rises, since the soft mesh 8 is a deformable mesh material, the top ball 9 pushes the soft mesh 8, causing the lower sand core to flip to the top, and the previously upper sand core to flip to the bottom, flipping back and forth, thus initially improving the heating efficiency. At the same time, when the servo motor 17 is activated, the output shaft of the servo motor 17 drives the first lead screw 25 to rotate, thereby causing the moving seat 14 to move back and forth, so that the top ball 9 pushes up every part of the soft mesh 8, further improving the heating efficiency.

[0049] Simultaneously, when the first lead screw 25 rotates, under the action of the pulley 35 and the belt 34, the third lead screw 27 rotates back and forth, causing the connecting seat 15 to move back and forth. Since the air outlet pipe of the heater 7 is a flexible hose, the connecting seat 15 drives the connecting cylinder 20 to move back and forth to release air, thereby further improving the heating efficiency. Furthermore, under the action of the first gear 30 and the rack 29, when the second connecting pipe 31 moves back and forth, the second connecting pipe rotates back and forth, causing the connecting cylinder 20 to rotate back and forth, thereby further improving the heating efficiency.

[0050] After the curing and heating are complete, the pull ring 26 can be pulled to disengage the fixing rod 42 from the fixing groove 44. At this time, the slider 43 is no longer restrained, and the connecting block 45 falls into the bottom wall of the chute 22 under the action of gravity. At this time, the soft mesh 8 is straightened and tilted, and the connecting block 45 is flush with the bottom wall of the discharge port 10. This allows the sand core to be automatically discharged under the action of gravity, improving the discharge efficiency and saving effort. After the discharge is complete, the handle 38 can be moved to slide the slider 43 to the top wall of the chute 22. At this time, the fixing rod 42 corresponds to the fixing groove 44. Under the action of the fixing spring 40, the fixing rod 42 is stably inserted into the fixing groove 44, which also facilitates disassembly.

10. A rapid curing method for sand cores in water outlet pipes according to claim 1, comprising the following steps: Step 1: Place the sand core into the conveyor hopper, then start the servo motor. When the servo motor starts, the output shaft of the servo motor drives the first lead screw to rotate. Under the action of the first driving bevel gear and the first driven bevel gear meshing, the rotating rod rotates. Under the action of the second driving bevel gear and the second driven bevel gear meshing, the second lead screw rotates. Under the action of the second limit rod, the conveyor hopper rises. When the conveyor hopper rises to correspond with the feed inlet, due to the inclined bottom of the conveyor hopper, the sand core in the conveyor hopper falls into the feed inlet under the action of gravity, and then enters the soft mesh, which facilitates feeding and saves labor. Step 2: The heater can be started, allowing hot air to enter the connecting cylinder through the first and second connecting pipes, and then be discharged through the air outlet, thereby heating and curing the sand core on the soft mesh. The cylinder can also be started, and the output shaft of the cylinder drives the top ball to rise and fall back and forth. When the top ball rises, since the soft mesh is a deformable mesh material, the top ball pushes the soft mesh, causing the sand core below to flip to the top, and the sand core above to flip to the bottom, flipping back and forth. At the same time, when the servo motor is started, the output shaft of the servo motor drives the first lead screw to rotate, causing the moving seat to move back and forth, so that the top ball lifts every part of the soft mesh. Step 3: When the first lead screw rotates, the third lead screw rotates back and forth under the action of the pulley and belt, which in turn causes the connecting seat to move back and forth. Since the air outlet pipe of the heater is a flexible hose, the connecting seat drives the connecting cylinder to move back and forth to release air. Under the action of the first gear and rack, when the second connecting pipe moves back and forth, it causes the second connecting pipe to rotate back and forth, which in turn causes the connecting cylinder to rotate back and forth, thereby further improving the heating efficiency. Step 4: After the curing and heating are complete, pull the ring to disengage the fixing rod from the fixing groove. At this time, the slider is no longer restrained, and the connecting block falls into the bottom wall of the chute under the action of gravity. The soft mesh is straightened and tilted. The connecting block is flush with the bottom wall of the discharge port, so that the sand core is automatically discharged under the action of gravity, which improves the discharge efficiency and saves more effort. Step 5: After the material is discharged, the handle can be moved so that the slider slides to the top wall of the groove. At this time, the fixing rod corresponds to the fixing groove. Under the action of the fixing spring, the fixing rod is stably inserted into the fixing groove, and heating and curing can continue.
