Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to a mold shell drying device that facilitates material loading. Background Technology

[0002] A mold shell drying device is used for rapidly drying the outer shell of molds. Its main functions are to remove moisture, improve mold strength, and shorten production cycles. It is widely used in industries such as casting, ceramics, and glass manufacturing to ensure the stability and precision of molds in subsequent processes. Through efficient drying, this device can significantly improve product quality and production efficiency.

[0003] A search revealed Chinese patent document publication number CN211651083U, which discloses a mold shell drying device, including a box body. A motor is installed at the upper end of the box body, and a rotating shaft is connected to the working end of the motor. The rotating shaft passes through the top of the box body and is located inside the box body. Several turntables are evenly distributed on the rotating shaft, and several lifting components are arranged around the lower circumference of the turntables. A mold shell is installed at the lower end of the lifting components.

[0004] In existing technologies, the loading of mold shells often involves manually hanging each shell onto a lifting device, resulting in low efficiency and increased labor intensity and time costs. Furthermore, human error during operation can easily damage the mold shells or cause unstable mounting, affecting the smooth progress of subsequent processes.

[0005] Based on this, the present invention designs a mold shell drying device that facilitates material feeding to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a mold shell drying device that facilitates material feeding.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mold shell drying device for easy loading includes a drying box, a drive mechanism, a loading mechanism, a loading plate, a heating device, and a heat recovery mechanism. The top of the drying box is fixedly connected to a drive mechanism for driving the entire drying box to perform loading and heating operations.

The loading plate is rotatably connected to the inner wall of the drying box. The bottom of the drying box is fixedly connected to a heating device. The top of the drying box is fixedly connected to a heat recovery mechanism for recovering and reusing the overflow energy during the drying process.

[0009] The feeding mechanism includes a locking component, connecting columns, a housing, gears, rack plate one, rack plate two, grippers, and a connector. The tops of the two connecting columns are fixedly connected to the bottom of the locking component, and the bottoms of the two connecting columns are fixedly connected to the top of the housing. The grippers are fixedly connected to the outer sides of the two rack plates one on the same side via four sliding columns, and the connector is fixedly connected to one end of the rack plate two.

[0010] Furthermore, the two ends of the two gears are rotatably connected to the inner wall of the outer casing via a rotating shaft. The outer side of the gear meshes with one side of the rack plate on the same side, and the outer sides of the two gears mesh with both sides of the rack plate.

[0011] Furthermore, the locking assembly includes a fixed shaft, a first spring, a plug, a second spring, a hemispherical rod, and an ellipsoidal block. The first spring is fixedly connected inside the fixed shaft, and the plug is slidably connected inside the fixed shaft. The front end of the plug has a right-angled trapezoidal cross-section, and the rear end of the plug is a cylinder. The distal ends of multiple second springs are fixedly connected inside the fixed shaft. The second springs are sleeved on the outer side of the rear cylinder of the plug. The bottom of the hemispherical rod is fixedly connected to the other end of the rack plate, and the top of the hemispherical rod contacts the bottom end of the first spring. An ellipsoidal block is slidably connected to the outer wall of the hemispherical rod.

[0012] Furthermore, the front end shape of the hemispherical rod and the outer shape of the ellipsoidal block are adapted to the front end shape of the insert.

[0013] Furthermore, the heat recovery mechanism includes a recovery pipe, a three-way sleeve, a diversion pipe, an exchange box, a heat conduction plate, an exhaust fan, and a gas supply pipe. One end of the recovery pipe is fixedly connected to the top of the drying box, and the other end of the recovery pipe is fixedly connected to the three-way sleeve. Diversion pipes are fixedly connected to both the left and right ends of the three-way sleeve. An exchange box is fixedly connected to one outer wall of the drying box, and two heat conduction plates are fixedly connected to the inner wall of the exchange box. An exhaust fan is fixedly connected to the top center of the exchange box, and a gas supply pipe is fixedly connected to the bottom center of the exchange box.

[0014] Furthermore, two heat-conducting plates divide the internal space of the exchange box into two energy storage chambers and a heat exchange chamber, with two ventilation holes on the top of the two energy storage chambers.

[0015] Furthermore, the drive mechanism includes a cylinder, a heat insulation shell, a motor, a rotating platform, and connecting piles. The cylinder is located at the top of the drying oven. A telescopic column is fixedly connected to the output end of the cylinder. A heat insulation shell is fixedly connected to the bottom of the telescopic column. A motor is fixedly connected to the top inner wall of the heat insulation shell. A rotating platform is fixedly connected to the output end of the motor. The bottom of the heat insulation shell is rotatably connected to the top of the rotating platform. Multiple connecting piles are fixedly connected to the outer wall of the rotating platform. The top of the fixed shaft is fixedly connected to the bottom of the connecting piles.

[0016] Furthermore, the heating device includes a heating tube, a blower, and a venting plate. The other end of the gas supply pipe is inserted into the heating device. The heating tube is used to perform secondary heating on the gas transported by the gas supply pipe. The blower is used to blow the heated gas upwards. The venting plate is used to ensure uniform gas output during the blowing out of hot gas.

[0017] Compared with the prior art, the advantages of this utility model are as follows: 1. The joint generates thrust through contact with the mold shell, pushing the rack plate upward, driving the gear to rotate, causing the grippers to close in the middle to clamp the mold shell, and the gripper position is fixed by the locking component. When the rack plate rises, the hemispherical rod compresses the spring and pushes the insert block to slide outward, completing the locking and ensuring clamping stability. This achieves convenient and stable feeding operation of the mold shell, thereby improving production efficiency and reducing manual intervention and operational errors.

[0018] 2. The high-temperature gas generated by the heating device enters the recovery pipe after drying the mold shell, and is then introduced into the energy storage chambers on both sides of the heat exchange box through the diversion pipe. The residual heat energy is used to heat the water in the energy storage chambers, while the pressure is regulated through the top vent. After the water absorbs heat and heats up, the exhaust fan introduces cold air from outside into the heat exchange chamber. As the cold air passes through the energy storage chamber, it absorbs heat from the water through the heat-conducting plates, thus preheating the cold air through heat exchange. This reduces the energy consumption for subsequent heating, thereby improving energy efficiency and reducing heat emissions to the environment. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of a stereoscopic view.

[0029] Example 1

[0030] Please refer to the accompanying drawings in the instruction manual. Figures 1-5 A mold shell drying device for easy loading includes a drying chamber 1, a drive mechanism 2, a loading mechanism 3, a loading plate 4, a heating device 5, and a heat recovery mechanism 6. The top of the drying chamber 1 is fixedly connected to the drive mechanism 2 for driving the entire drying chamber 1 to perform loading and heating operations. The bottom of the drive mechanism 2 is fixedly connected to the loading mechanism 3 to facilitate the entry of the mold shell into the drying chamber 1. The loading plate 4 is rotatably connected to the inner wall of the drying chamber 1. The bottom of the drying chamber 1 is fixedly connected to the heating device 5. The top of the drying chamber 1 is fixedly connected to the heat recovery mechanism 6 for recovering and reusing the overflow energy during the drying process.

[0031] In this invention, the drying chamber 1 is the main body of the entire drying device. The outer wall of the drying chamber 1 is made of heat-insulating material (aluminum silicate fiber as the main material). The loading mechanism 3 is driven by the drive mechanism 2 to lift and lower, thereby completing the loading and unloading. After loading, the loading mechanism 3 rotates, which in turn drives the loading plate 4 to rotate inside the drying chamber 1. The loading plate 4 is surrounded by sealing gaskets to prevent safety hazards caused by high-temperature gas leakage. The loading plate 4 has a groove in the middle for placing the mold shell. The mold shell is placed in the groove, and the drive mechanism 2 is turned on to move the loading mechanism 3 up and down, thereby completing the loading and unloading operation. After the loading operation is completed, the heating device 5 and the heat recovery mechanism 6 are turned on, allowing the high-temperature gas to pass through the mold shell for drying and recovering and reusing the residual heat of the high-temperature gas.

[0032] The feeding mechanism 3 includes a locking assembly, connecting posts 305, a housing 306, gears 307, rack plate one 308, rack plate two 310, grippers 309, and connectors 311. The tops of the two connecting posts 305 are fixedly connected to the bottom of the locking assembly, and the bottoms of the two connecting posts 305 are fixedly connected to the top of the housing 306. The two ends of the two gears 307 are rotatably connected to the inner wall of the housing 306 through a rotating shaft. The outer side of the gears 307 meshes with one side of the rack plate one 308 on the same side, and the outer side of the two gears 307 meshes with both sides of the rack plate two 310 respectively. The grippers 309 are fixedly connected to the other side of the two rack plates one 308 on the same side through four sliding posts. The connectors 311 are fixedly connected to one end of the rack plate two 310.

[0033] In this utility model, the entire feeding mechanism 3 descends, causing the connector 311 to contact the top of the mold shell, thereby generating an upward thrust. This causes the rack plate 310 to move upward, thereby driving the two gears 307 to rotate. When the gears 307 rotate, they drive multiple rack plates 308 to close in the middle, thereby driving the two grippers 309 to close in the middle to complete the clamping of the mold shell. Then, the locking component locks the position of the grippers 309. Finally, the drive mechanism 2 operates to complete the next clamping and feeding operation.

[0034] The locking assembly includes a fixed shaft 301, a first spring 302, a plug block 303, a second spring 304, a hemispherical rod 312, and an ellipsoidal block 313. The first spring 302 is fixedly connected inside the fixed shaft 301, and the plug block 303 is slidably connected inside the fixed shaft 301. The front end of the plug block 303 has a right-angled trapezoidal cross-section, and the rear end of the plug block 303 is a cylinder. The distal ends of multiple second springs 304 are fixedly connected inside the fixed shaft 301. The second springs 304 are sleeved on the outer side of the rear cylindrical part of the plug block 303. The bottom of the hemispherical rod 312 is fixedly connected to the other end of the rack plate 310, and the top of the hemispherical rod 312 contacts the bottom end of the first spring 302. The outer wall of the hemispherical rod 312 is slidably connected to the ellipsoidal block 313, and the outer shape of the ellipsoidal block 313 is adapted to the front end shape of the plug block 303.

[0035] In this invention, the upward movement of the rack plate 310 drives the hemispherical rod 312 upward into the fixed shaft 301 and compresses the spring 302. During the upward movement of the hemispherical rod 312, the arc-shaped outer side of the hemispherical plate causes the three inserts 303 to slide outward under pressure, thereby compressing the spring 304 until the hemispherical end of the hemispherical rod 312 separates from the inserts 303. The spring 304 then returns to its original shape, causing the inserts 303 to reset and insert them between the hemispherical rod 312 and the ellipsoidal block 313, completing the locking operation. This ensures that the gripper 309 maintains stability after loading, and during unloading, the drive mechanism 2 presses down on the mold shell again to make the joint... 311 moves slightly upward, causing the ellipsoid to contact the insert block 303 and press the insert block 303 outward, causing the insert block 303 to move outward again and reset when the position of the insert block 303 is aligned with the bottom of the ellipsoid block 313. At this time, the rack plate 310 is pushed downward by its own weight and the elastic force of the spring 304. The insert block 303 pushes the ellipsoid block 313 upward so that the end of its ellipsoid rod contacts the ellipsoid. The three insert blocks 303 move outward, the entire hemispherical rod 312 is unlocked, and the hemispherical rod 312 and the rack plate 310 move downward, thereby rotating the gear 307 in the opposite direction, causing the gripper 309 to release, and the material is unloaded by pushing the connector 311.

[0036] The heat recovery mechanism 6 includes a recovery pipe 601, a three-way sleeve 602, a diversion pipe 603, an exchange box 604, a heat-conducting plate 605, an exhaust fan 606, and a gas supply pipe 607. One end of the recovery pipe 601 is fixedly connected to the top of the drying box 1, and the other end of the recovery pipe 601 is fixedly connected to the three-way sleeve 602. The two ends of the three-way sleeve 602 are both fixedly connected to the diversion pipe 603. The exchange box 604 is fixedly connected to one outer wall of the drying box 1. Two heat-conducting plates 605 are fixedly connected to the inner wall of the exchange box 604. The two heat-conducting plates 605 divide the internal space of the exchange box 604 into two energy storage chambers and a heat exchange chamber. The exhaust fan 606 is fixedly connected to the middle of the top of the exchange box 604, and the gas supply pipe 607 is fixedly connected to the middle of the bottom of the exchange box 604.

[0037] In this invention, the high-temperature gas blown out by the heating device 5 enters the recovery pipe 601 after drying the mold shell, and then enters the diversion pipe 603 through the transport action of the recovery pipe 601. From there, it flows into the energy storage chambers on both sides of the exchange box 604. The energy storage chambers contain a certain amount of water, and because the bottom end of the diversion pipe 603 is close to the bottom of the exchange box 604, the heat exchange stroke is increased, thereby improving the heat exchange efficiency. The water is heated by the residual heat energy of the high-temperature gas. Furthermore, an air vent is provided at the top of the energy storage chamber to prevent excessive pressure from damaging the exchange box 604. After the water absorbs the residual heat energy of the high-temperature gas, it heats up. At this time, the exhaust fan 606 is turned on to draw in cold air from the outside. The cold air enters the heat exchange chamber through the exhaust fan 606 and passes through the energy storage chambers on both sides. According to the second law of thermodynamics, the heat inside the heated water is transferred to the central heat exchange chamber through the heat conduction plate 605, thereby initially heating the cold air. This facilitates subsequent secondary heating of the cold air and saves energy consumption.

[0038] The drive mechanism 2 includes a cylinder 201, a heat insulation shell 202, a motor 203, a rotating platform 204, and connecting pins 205. The cylinder 201 is located on the top of the drying chamber 1. The output end of the cylinder 201 is fixedly connected to the heat insulation shell 202. The motor 203 is fixedly connected to the inner top wall of the heat insulation shell 202. The output end of the motor 203 is fixedly connected to the rotating platform 204. The bottom of the heat insulation shell 202 is rotatably connected to the top of the rotating platform 204. Multiple connecting pins 205 are fixedly connected to the outer wall of the rotating platform 204. The top of the fixed shaft 301 is fixedly connected to the bottom of the connecting pins 205.

[0039] In this invention, the operation of the cylinder 201 drives the telescopic column to move up and down, thereby driving the heat insulation shell 202 to move up and down. Through the connection of the heat insulation shell 202, the rotating table 204 and the connecting pile 205 can move vertically synchronously, thereby driving the feeding mechanism 3 to move vertically to complete the feeding and unloading operations. Furthermore, the operation of the motor 203 drives the rotating table 204 to rotate at the bottom of the heat insulation shell 202, thereby alternating feeding during the feeding process and ensuring that the mold shell is heated and dried evenly during the subsequent drying process, thus improving the feeding efficiency and drying efficiency.

[0040] The heating device 5 includes a heating tube, a blower, and a vent plate. The other end of the gas supply pipe 607 is inserted into the heating device 5. The heating tube is used to heat the gas transported by the gas supply pipe 607 in a secondary manner. The blower is used to blow the heated gas upward. The vent plate is used to ensure the uniformity of the gas output during the blowing out of the hot gas.

[0041] In this invention, the gas, after being preheated, is heated to a specified temperature by a heating tube and then blown out by a blower. The gas is restricted by the air vent plate, which allows the gas to pass through the through holes in the air vent plate, thus making the gas flow more uniform. This results in more uniform heating of the mold shell and improves the drying efficiency.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
