Description

Technical Field

[0001] This utility model belongs to the field of casting technology, and in particular relates to a rapid cooling device for castings. Background Technology

[0002] In the casting industry, the cooling process of castings has a crucial impact on their quality and performance. Natural cooling relies on the natural heat exchange between the casting and the surrounding air to reduce the temperature, which is relatively slow. This not only prolongs the production cycle and reduces production efficiency, but may also cause problems such as oxidation and deformation of castings during long-term cooling, affecting their dimensional accuracy and surface quality. Therefore, cooling devices are needed to cool castings quickly.

[0003] However, in the use of existing rapid cooling devices for castings, the degree of contact between different parts of the casting and the coolant varies, causing different degrees of shrinkage inside the casting, resulting in greater internal stress and causing defects such as deformation and cracks in the casting after cooling. Utility Model Content

[0004] The purpose of this invention is to provide a rapid cooling device for castings. By setting up a rotating mechanism, it solves the problem that in existing rapid cooling devices for castings, the contact degree between different parts of the casting and the coolant varies during use, causing different degrees of shrinkage inside the casting and generating large internal stress, which leads to defects such as deformation and cracks in the casting after cooling.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a rapid cooling device for castings used in casting, including a cooling box, on which a rotating mechanism and a stirring mechanism are provided;

[0007] The cooling tank is equipped with a holding basket, and the bottom of the cooling tank is connected to an outlet pipe with a valve. The rotating mechanism includes a rotating shaft rotatably connected to the inner wall of the bottom of the cooling tank. The bottom of the rotating shaft extends to the outside of the cooling tank. A hollow rod is rotatably connected to the outer wall of the rotating shaft. Several connecting rods are fixedly connected to the outer wall of the hollow rod. The stirring mechanism includes a motor fixedly connected to the bottom of the cooling tank. The output shaft of the motor is fixedly connected to the rotating shaft via a coupling. Several stirring rods are fixedly connected to the outer wall of the rotating shaft.

[0008] Furthermore, each of the several connecting rods is fixedly connected to a positioning cylinder on the side away from each other, and each of the several positioning cylinders is fixedly connected to a connecting rod 2 on the side away from the several connecting rods 1.

[0009] Furthermore, a number of positioning rods are fixedly connected to the bottom of the holding basket, and the bottoms of the positioning rods extend into a number of positioning cylinders respectively. A ring is fixedly connected to the inner wall of the cooling box.

[0010] Furthermore, a trapezoidal groove is provided on the inner wall of the ring, and a number of trapezoidal sliders are slidably connected to the inner wall of the trapezoidal groove. The side of the trapezoidal sliders away from the trapezoidal groove is fixedly connected to a number of connecting rods.

[0011] Furthermore, a support frame is rotatably connected to the outer wall of the first rotating shaft and the hollow rod, and a second rotating shaft passes through the support frame. The right side of the second rotating shaft is rotatably connected to the cooling box, and the second rotating shaft is rotatably connected to the support frame.

[0012] Furthermore, bevel teeth are fixedly connected to the outer walls of both the first rotating shaft and the hollow rod, and bevel teeth are fixedly connected to the outer wall of the second rotating shaft, with the second bevel teeth meshing with the two first bevel teeth.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting up a rotating mechanism, when the casting needs to be cooled, the basket can be placed into the cooling box, and several positioning rods can be positioned in several positioning cylinders. Then, the motor is started, and the motor will drive the rotating shaft to rotate. At this time, the hollow rod will rotate with the rotating shaft under the interaction of the two bevel teeth one and two bevel teeth. During this process, several positioning cylinders will drive the basket to rotate through the positioning rods connected by the connecting rod one, so that the casting rotates in the cooling box. When the positioning cylinders rotate, the trapezoidal slider on the connecting rod two will slide in the trapezoidal groove, thereby ensuring the stability of the positioning cylinders during rotation. This allows all parts of the casting to have a chance to contact the cooling medium in the cooling box evenly, avoiding local cooling that is too fast or too slow, effectively improving the uniformity of cooling, reducing problems such as internal stress, deformation and cracks in the castings caused by uneven cooling, and improving the quality and performance of the castings.

[0015] 2. By setting up a stirring mechanism, when the motor drives the rotating shaft to rotate, the rotating shaft will also drive several stirring rods to rotate around the rotating shaft, stirring the coolant in the cooling tank. This prevents impurities from settling in the cooling tank. Furthermore, due to the setting of two bevel teeth, the rotation direction of the stirring rods is opposite to the rotation direction of the basket, making it difficult for impurities to settle at the bottom of the cooling tank. This reduces the possibility of impurities adhering to the surface of the castings, helping to maintain the cleanliness of the casting surface. It also prevents impurities from accumulating and affecting the performance of the cooling system. Moreover, the reverse rotation design increases the relative speed between the castings and the coolant, accelerating the heat transfer rate, thereby improving cooling efficiency, shortening the cooling time of the castings, and improving production efficiency.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-5 As shown, this utility model is a rapid cooling device for castings, including a cooling box 1, a rotating mechanism 2 and a stirring mechanism 3 on the cooling box 1, a holding basket 101 inside the cooling box 1, and a liquid outlet pipe 102 with a valve connected to the bottom of the cooling box 1.

[0026] The rotating mechanism 2 includes a rotating shaft 211 rotatably connected to the inner wall of the bottom of the cooling box 1. The bottom of the rotating shaft 211 extends to the outside of the cooling box 1. A hollow rod 212 is rotatably connected to the outer wall of the rotating shaft 211. Several connecting rods 213 are fixedly connected to the outer wall of the hollow rod 212. Positioning cylinders 214 are fixedly connected to the sides of the several connecting rods 213 that are away from each other. Connecting rods 215 are fixedly connected to the sides of the several positioning cylinders 214 that are away from the several connecting rods 213. Several positioning rods 216 are fixedly connected to the bottom of the holding basket 101. The bottoms of the several positioning rods 216 extend into the several positioning cylinders 214 respectively. A ring 218 is fixedly connected to the inner wall of the cooling box 1. A trapezoidal groove 219 is provided on the inner wall of the ring 218. Several trapezoidal sliders 220 are slidably connected to the inner wall of the trapezoidal groove 219. The side of the trapezoidal sliders 220 away from the trapezoidal groove 219 is fixedly connected to several connecting rods 215. By setting the rotating mechanism 2, all parts of the casting can have a chance to contact the cooling medium in the cooling box 1 evenly, avoiding local cooling that is too fast or too slow, effectively improving the uniformity of cooling, reducing problems such as internal stress, deformation and cracks in the casting caused by uneven cooling, and improving the quality and performance of the casting.

[0027] The stirring mechanism 3 includes a motor 311 fixedly connected to the bottom of the cooling tank 1. The output shaft of the motor 311 is fixedly connected to a rotating shaft 211 via a coupling. Several stirring rods 313 are fixedly connected to the outer wall of the rotating shaft 211. A support frame 314 is rotatably connected to the outer walls of the rotating shaft 211 and the hollow rod 212. A rotating shaft 315 passes through the support frame 314. The right side of the rotating shaft 315 is rotatably connected to the cooling tank 1. The rotating shaft 315 is rotatably connected to the support frame 314. A bevel gear 31 is fixedly connected to the outer walls of both the rotating shaft 211 and the hollow rod 212. 6. A bevel gear 317 is fixedly connected to the outer wall of the rotating shaft 315. The bevel gear 317 meshes with two bevel gears 316. By setting the stirring mechanism 3, impurities are difficult to settle at the bottom of the cooling box 1, reducing the possibility of impurities adhering to the surface of the casting, which helps to maintain the cleanliness of the casting surface. At the same time, it can also prevent impurities from accumulating and affecting the performance of the cooling system. Moreover, the reverse rotation design increases the relative speed between the casting and the coolant, accelerates the heat transfer rate, thereby improving the cooling efficiency, shortening the cooling time of the casting, and improving production efficiency.

[0028] A specific application of this embodiment is as follows: In use, firstly, the casting to be cooled is poured into the holding basket 101. Then, sufficient coolant is added to the cooling tank 1. Next, the holding basket 101 is placed inside the cooling tank 1, with several positioning rods 216 positioned within several positioning cylinders 214. Then, the motor 311 is started, driving the rotating shaft 211 to rotate. At this time, the hollow rod 212 rotates along with the rotating shaft 211 due to the interaction of the two bevel teeth 316 and 317. During this process, several positioning cylinders 214, connected by the connecting rod 213, drive the holding basket 101 to rotate via the positioning rods 216, causing the casting to rotate within the cooling tank 1. While the positioning cylinders 214 are rotating, the connecting rods 213 connect... The trapezoidal slider 220 on rod 215 slides within the trapezoidal groove 219, ensuring the stability of the positioning cylinder 214 during rotation. When the motor 311 drives the rotating shaft 211 to rotate, the rotating shaft 211 also drives several stirring rods 313 to rotate around the rotating shaft 211, stirring the coolant in the cooling tank 1 and preventing impurities from settling in the cooling tank 1. Furthermore, due to the setting of the two conical teeth 316 and 317, the rotation direction of the several stirring rods 313 is opposite to the rotation direction of the holding basket 101. After cooling is completed, the outlet pipe 102 with a valve is opened to collect the coolant. After the castings in the holding basket 101 have drained, the holding basket 101 and the castings in the holding basket 101 can be removed.
