Description

Technical Field

[0001] This utility model relates to the field of wax mold casting technology, specifically to a high-efficiency cooling device for wax molds. Background Technology

[0002] In the investment casting process, after the wax model is made, it needs to be cooled and set. The common practice is to place the wax model directly on the water surface to dry naturally, or simply immerse it in cooling water to cool it.

[0003] Chinese patent CN213288559U discloses a wax model cooling device, including a cooling pool filled with cooling water, and a conveyor belt that drives the wax model forward. The conveyor belt is sleeved on a transmission roller, and a drive mechanism controls the rotation of the transmission roller to drive the conveyor belt. The cooling pool includes an inlet area, a cooling conveying area, and an outlet area. The conveyor belt is placed in the cooling conveying area, and at least its bottom is immersed in the cooling water. The drive mechanism is located outside the cooling pool. The outer surface of the conveyor belt is fixed with a soft, elastic material that will indent when pressed by a wax model floating in the water. However, this device still has the following problems in use:

[0004] When long wax castings are cooled, the wax castings located in deeper parts will be subjected to greater water pressure. Prolonged immersion will cause the wax castings at the bottom of the cooling pool to deform, affecting the molding effect of the wax casting.

[0005] Based on this, the present invention designs a high-efficiency cooling device for wax molds 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 high-efficiency cooling device for wax molds.

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

[0008] A high-efficiency cooling device for wax models includes a cooling pool, a rotary lifting and transferring mechanism, mounting boxes, and a closing mechanism. The rotary lifting and transferring mechanism is installed inside the cooling pool to control the rotation and lifting of the wax model, thereby increasing the cooling effect. The rotary lifting and transferring mechanism includes a rotary drive assembly for controlling the rotation of a movable component, a vertical moving assembly for the vertical movement of the movable component, a movable component for moving the mounting boxes together, and a lifting assembly for controlling the wax model's movement in and out of the cooling pool. The rotary drive assembly and the vertical moving assembly are both installed inside the cooling pool. The movable component is mounted on the rotary drive assembly and connected to the vertical moving assembly. Multiple mounting boxes are mounted on the movable component. The lifting assembly is mounted on the rotary drive assembly. Closing mechanisms for controlling the opening and closing of slots on the mounting boxes are installed on the movable component and the mounting boxes.

[0009] Furthermore, the upper end of the mounting box is provided with a sealing cover that can be flipped open and closed, and the side wall of the mounting box is provided with slots that allow coolant from the cooling pool to enter the interior of the mounting box.

[0010] Furthermore, the rotation drive assembly includes a drive turntable, a fixed sleeve rod, a movable rod, and a fixed triangular plate. The drive turntable is rotatably disposed at the bottom of the cooling pool, and a fixed sleeve rod is fixedly installed at the upper end of the drive turntable. The middle part of the fixed sleeve rod is slidably connected to the movable rod. A fixed triangular plate is fixedly installed at the upper end of the movable rod.

[0011] Furthermore, the movable component includes a moving rod and a limiting block. Each of the three extended ends of the fixed triangular plate is provided with a sliding groove, and the moving rod is slidably connected to the sliding groove. A limiting block is provided above the fixed triangular plate, and the limiting block is fixedly connected to the upper end of the moving rod. An installation box is fixedly installed in the middle of the moving rod.

[0012] Furthermore, the size of the limiting block is larger than the size of the sliding groove;

[0013] Furthermore, the vertical moving assembly includes a limiting ring plate and a guide wheel. The guide wheel is rotatably mounted on the lower end of the moving rod. The limiting ring plate is fixedly installed at the inner bottom of the cooling pool. A limiting ring groove is provided at the upper end of the limiting ring plate, with the left side of the limiting ring groove being the high end and the right side being the low end. The guide wheel is in rolling connection with the limiting ring groove.

[0014] Furthermore, the lifting assembly includes a push cylinder and a fixed ring plate. The push cylinder is fixedly installed at the middle of the front end of the fixed sleeve rod, and the fixed ring plate is rotatably connected to the movable rod through a bearing. The output end of the push cylinder is fixedly connected to the fixed ring plate.

[0015] Furthermore, the closing mechanism includes a closing push cylinder, a baffle, and a connecting plate. The closing push cylinder is fixedly installed in the middle of the moving rod. The side wall of the mounting box is provided with a sliding groove. The baffle is slidably connected to the sliding groove. The two baffles on the side wall of the mounting box are fixedly connected by the connecting plate. The output end of the closing push cylinder is fixedly connected to the connecting plate. The baffle is also provided with a slot with the same shape and size as the slot on the mounting box, and the height of the baffle is less than the height of the mounting box.

[0016] Compared with the prior art, the advantages of this invention are as follows: the cooperation of the rotation drive component, the vertical movement component, and the movable component allows the wax model to continuously rotate and change position in the coolant, ensuring continuous flow of coolant in the cooling pool. This avoids the wax model being placed in the same position for a long time, which would cause the temperature of the coolant at that position to rise and affect the cooling effect. It also avoids the probability of deformation caused by the lower end of a long wax model being at the bottom of the cooling pool for a long time. This not only improves the cooling quality of the wax model but also ensures the molding quality of the wax model. Furthermore, it prevents residue floating on the surface of the coolant from entering the mounting box and adhering to the wax model, reducing the extra workload of manually removing residue from the surface of the wax model later.

Detailed Implementation

[0024] 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.

[0025] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0026] In some embodiments, please refer to the accompanying drawings. Figures 1-4 A high-efficiency cooling device for wax models includes a cooling pool 1, a rotary lifting and transferring mechanism 2, a mounting box 3, and a closing mechanism 5. The rotary lifting and transferring mechanism 2, used to control the rotation and lifting of the wax model to enhance its cooling effect, is installed within the cooling pool 1. The rotary lifting and transferring mechanism 2 includes a rotary drive assembly 21 for controlling the rotation of a movable component 23, a vertical moving assembly 22 for the vertical movement of the movable component 23, a movable component 23 for moving the mounting box 3 together, and a lifting assembly 24 for controlling the wax model's movement in and out of the cooling pool 1. The rotary drive assembly 21 is installed within the cooling pool 1. Inside the cooling pool 1, the vertical moving component 22 is also installed inside the cooling pool 1, and the movable component 23 is installed on the rotation drive component 21 and connected to the vertical moving component 22; and multiple mounting boxes 3 are installed on the movable component 23; the lifting component 24 is installed on the rotation drive component 21; the upper end of the mounting box 3 is provided with a sealing cover that can be flipped open and opened, and the side wall of the mounting box 3 is provided with slots that allow the coolant in the cooling pool 1 to enter the interior of the mounting box 3; the movable component 23 and the mounting box 3 are equipped with a closing mechanism 5 for controlling the opening and closing of the slots provided on the mounting box 3;

[0027] In this invention, the operator uses the lifting assembly 24 to drive the rotation drive assembly 21 and the movable assembly 23 upwards until the upper end of the mounting box 3 mounted on the movable assembly 23 is higher than the upper surface of the cooling pool 1. Then, the cover of the mounting box 3 is opened, and the wax model is placed inside. Next, the lifting assembly 24 controls the rotation drive assembly 21 to drive the movable assembly 23 downwards, immersing the wax model in the coolant in the cooling pool 1. The coolant can enter through the slots on the mounting box 3, cooling the wax model. Finally, the rotation drive assembly 21 is activated, rotating the drive assembly. The operation of component 21 drives the movable component 23 to rotate, and during the rotation, the vertical moving component 22 also controls the movable component 23 to move up and down continuously. The cooperation of the rotation drive component 21, the vertical moving component 22 and the movable component 23 makes the wax model rotate and change position in the coolant, so that the coolant in the cooling pool 1 flows continuously. This avoids the wax model being placed in the same position for a long time, which would cause the temperature of the coolant at that position to rise and affect the cooling effect. It also avoids the probability of the wax model deforming because the lower end of the long wax model is at the bottom of the cooling pool 1 for a long time. This not only improves the cooling quality of the wax model, but also ensures the molding quality of the wax model.

[0028] During the cooling process, the residue on the surface of the wax model will float to the surface of the coolant due to its low gravity. After the wax model has cooled down, the rotation drive component 21 stops working, and then the closing mechanism 5 works to close the slot on the outer wall of the mounting box 3. Then, the lifting component 24 works again to drive the rotation drive component 21 to rise. At this time, the slot is closed, which also prevents the residue floating on the surface of the coolant from entering the mounting box 3 and adhering to the wax model. This reduces the extra workload of manually removing the residue from the surface of the wax model later.

[0029] The rotation drive assembly 21 includes a drive turntable 211, a fixed sleeve rod 212, a movable rod 213, and a fixed triangular plate 214. The drive turntable 211 is rotatably disposed at the inner bottom of the cooling pool 1. The fixed sleeve rod 212 is fixedly installed at the upper end of the drive turntable 211. The middle part of the fixed sleeve rod 212 is slidably connected to the movable rod 213. The fixed triangular plate 214 is fixedly installed at the upper end of the movable rod 213.

[0030] The drive turntable 211 can be driven by a motor;

[0031] The movable component 23 includes a moving rod 231 and a limiting block 233. Each of the three extended ends of the fixed triangular plate 214 is provided with a sliding groove 232, and the moving rod 231 is slidably connected to the sliding groove 232. A limiting block 233 is provided above the fixed triangular plate 214, and the limiting block 233 is fixedly connected to the upper end of the moving rod 231. An installation box 3 is fixedly installed in the middle of the moving rod 231.

[0032] The size of the limiting block 233 is larger than the size of the sliding groove 232 to prevent the moving rod 231 from falling off when the lifting component 24 moves the wax model out of the coolant.

[0033] The vertical moving assembly 22 includes a limiting ring plate 221 and a guide wheel 223. The guide wheel 223 is rotatably mounted on the lower end of the moving rod 231. The limiting ring plate 221 is fixedly installed at the inner bottom of the cooling pool 1. A limiting ring groove 222 is provided at the upper end of the limiting ring plate 221, with the left side of the limiting ring groove 222 being the high end and the right side being the low end. The guide wheel 223 is in rolling connection with the limiting ring groove 222.

[0034] The lifting assembly 24 includes a push cylinder 241 and a fixed ring plate 242. The push cylinder 241 is fixedly installed at the middle of the front end of the fixed sleeve rod 212. The fixed ring plate 242 is rotatably connected to the movable rod 213 through a bearing. The output end of the push cylinder 241 is fixedly connected to the fixed ring plate 242.

[0035] A pneumatic slip ring is also provided on the fixed ring plate 242, and the stator of the pneumatic slip ring is fixedly connected to the fixed ring plate 242, and the rotor of the pneumatic slip ring is fixedly connected to the movable rod 213.

[0036] In this invention, the push cylinder 241 operates, causing the fixed ring plate 242 to move upward along the fixed sleeve rod 212 following the movable rod 213. The movable rod 213 then moves the fixed triangular plate 214 upward together. During the movement, the top of the fixed triangular plate 214 lifts the limit block 233 and moves the movable rod 231 upward together until the mounting box 3 is completely removed from the coolant in the cooling pool 1. Then, the cover on the upper surface of the mounting box 3 is opened, the wax model is placed inside the mounting box 3, and then the cover is closed. The push cylinder 241 is started again, and the push cylinder 241 operates, causing the movable rod 213 to reset, causing the mounting box 3 to move downward until the mounting box 3 is completely immersed in the coolant in the cooling pool 1. Then, the drive turntable 211 is started, and the drive turntable 21... 1. The rotation drives the fixed sleeve rod 212, the movable rod 213, and the fixed triangular plate 214 to rotate together; and multiple movable rods 231 and guide wheels 223 will follow the fixed triangular plate 214 to rotate together along the limiting ring groove 222. When the guide wheel 223 moves from the low end to the high end of the limiting ring groove 222, the movable rod 231 will drive the mounting box 3 to move upward along the sliding groove 232; by driving the turntable 211 to rotate continuously, the movable rod 231 will continuously switch between the low end and the high end of the limiting ring groove 222, so that the mounting box 3 can move up and down continuously while rotating; so that the wax model can continuously rotate and change position in the coolant to ensure that the coolant in the cooling pool 1 flows continuously, and avoid the lower end of the wax model being in a position with high water pressure in the coolant for a long time.

[0037] The closing mechanism 5 includes a closing push cylinder 51, a baffle 53, and a connecting plate 54. The closing push cylinder 51 is fixedly installed in the middle of the moving rod 231. The side wall of the mounting box 3 is provided with a sliding groove 52. The baffle 53 is slidably connected to the sliding groove 52. The two baffles 53 on the side wall of the mounting box 3 are fixedly connected by the connecting plate 54. The output end of the closing push cylinder 51 is fixedly connected to the connecting plate 54. The baffle 53 is also provided with a slot with the same shape and size as the slot on the mounting box 3, and the height of the baffle 53 is less than the height of the mounting box 3.

[0038] In this utility model, after the wax model has cooled down, the closed push cylinder 51 operates to drive the baffle 53 to move along the slide groove 52 along with the connecting plate 54, so that the slot on the baffle 53 is misaligned with the slot on the mounting box 3. At this time, the baffle 53 blocks the slot on the mounting box 3, preventing the residue floating on the surface of the coolant from entering the mounting box 3 and adhering to the wax model when the mounting box 3 is removed from the coolant.

[0039] 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.
