Description

Technical Field

[0001] This utility model belongs to the field of casting equipment, and is designed for lost-wax casting, particularly relating to a water-cooling device for casting wax molds. Background Technology

[0002] Lost-wax casting is a high-precision metal casting process. Its core is to use a wax model to replace the shape of the casting, followed by shell making, dewaxing, and pouring metal into the mold. The wax model is made by pouring molten wax into the mold, pouring out the excess wax, and allowing the remaining wax to form a uniform layer. After cooling, the wax model is formed.

[0003] Currently, wax molds are cooled statically or by water after the wax is poured out. However, most water-cooling fixtures have a single function, only serving a cooling purpose. The operation of shaking the wax on the inner wall of the mold still needs to be done manually, which is not conducive to improving production efficiency. Utility Model Content

[0004] This utility model addresses the technical problems existing in the aforementioned wax mold water cooling devices by proposing a casting wax mold water cooling device with a reasonable design and functions of cooling and wax mixing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a water cooling device for casting wax molds, including a water tank, an inclined cantilever above the water tank, bearing seats near both ends of the cantilever, a transmission mechanism near the bottom of the cantilever, and a shaking mechanism near the top of the cantilever. The shaking mechanism includes a rotating groove, an inner ring plate and an outer ring plate are provided on the rotating groove, the cross-section of the inner ring plate is curved with its curved opening facing the outer ring plate, the cross-section of the outer ring plate is curved with its curved opening facing the inner ring plate, at least four sets of clamping mechanisms arranged in a circular array are provided between the outer ring plate and the inner ring plate, each clamping mechanism including two clamping arms, and multiple water inlets spaced apart from the clamping mechanisms are provided on the outer circumference of the outer ring plate.

[0006] Preferably, the axial length of the outer ring plate is greater than the axial length of the inner ring plate.

A connecting pipe communicating with the keyed hole is provided on one side of the mounting seat. A spring is provided inside the connecting pipe. A movable rod is provided at the center of the spring. A baffle is provided at one end of the movable rod. A locking plate that cooperates with the clamping arm is provided at the other end of the movable rod.

[0008] Preferably, the clamping arm includes a clamping shaft, and the clamping shaft has three clamping blocks spaced 120 degrees apart in the portion located between the inner ring plate and the outer ring plate. The other end of the clamping shaft is provided with an anti-loosening nut located outside the mounting base.

[0009] Preferably, the transmission mechanism includes a bevel gear transmission assembly, the power input end of which is vertically downward and mounted on a reduction gearbox, the reduction gearbox contains a pulley reducer, and the power input end of the pulley reducer is equipped with a motor.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model provides a water-cooling device for casting wax molds. The wax mold in the mold is held by a clamping mechanism along with the mold. A transmission mechanism drives the cantilever to rotate, simultaneously rotating the shaking mechanism and all clamping mechanisms. The wax mold is in contact with water in a water tank at its lowest position, thus achieving water cooling and ensuring the uniformity of the wax mold within the mold.

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0015] Examples, such as Figures 1-4 As shown, the present invention provides a water cooling device for casting wax molds, including a water tank 1. A cantilever 2 is inclinedly arranged above the water tank 1. Bearing seats 3 are arranged near both ends of the cantilever 2. A transmission mechanism 4 is arranged near the bottom end of the cantilever 2. A shaking mechanism 5 is arranged near the top end of the cantilever 2. The shaking mechanism 5 includes a rotating groove 51. An inner ring plate 52 and an outer ring plate 53 are arranged on the rotating groove 51. The cross-section of the inner ring plate 52 is curved and its curved opening faces the outer ring plate 53. The cross-section of the outer ring plate 53 is curved and its curved opening faces the inner ring plate 52. At least four sets of clamping mechanisms 6 arranged in a circular array are arranged between the outer ring plate 53 and the inner ring plate 52. The clamping mechanism 6 includes two clamping arms 61. Multiple water inlets 54 are arranged at intervals with the clamping mechanisms 6 on the outer circumference of the outer ring plate 53.

[0016] Specifically, the water tank 1, cantilever 2, transmission mechanism 4, and bearing seat 3 are all housed in a box 7. The inner wall of the box has a block structure for mounting the bearing seat. The front, back, top, bottom, and left side of the box 7 are all box plates, while the right side of the box 7 is open. The center of the rotating groove 51 has a mounting hole, which is connected to the cantilever 2 by a key. The end of the cantilever 2 has a limiting nut to restrict the axial movement of the rotating groove 51. The shaking mechanism 5 is installed at the end of the box 7, and the openings of the rotating groove 51, the inner ring plate 52, and the outer ring plate 53 all face the outside of the box 7 to facilitate the real-time loading and unloading of the mold with the wax model attached. More specifically, the wax model in the mold is held together with the mold by the clamping mechanism 6. The inner ring plate 52 and the outer ring plate 53 provide limiting support for the mold to ensure the stability of the mold movement. The transmission mechanism 4 drives the cantilever 2 to rotate while simultaneously driving the shaking and equalizing mechanism 5 and all the clamping mechanisms 6 to rotate. The water level in the water tank 1 is higher than the level of the outer ring plate 53 at its lowest position. Therefore, when the clamping mechanism 6 moves to its lowest position, the mold can come into contact with the water in the water tank 1, thereby achieving the purpose of water cooling. In this way, this equipment achieves the purpose of water cooling by rotation and also ensures the uniformity of the wax model in the mold, which is beneficial to ensuring the quality of the wax model after demolding.

[0017] To improve the stability of the mold as it rotates with the shaking mechanism 5, the axial length of the outer ring plate 53 provided by this invention is greater than the axial length of the inner ring plate 52. This provides two support lines with staggered axial spans to support the mold, which, in conjunction with the clamping mechanism 6, ensures the stability of the mold. Both the inner ring plate 52 and the outer ring plate 53 have curved openings, especially the outer ring plate 53. This allows the outer ring plate 53 to scoop in a certain volume of water at its lowest horizontal position. After the outer ring plate 53, which is holding the mold, is completely separated from the water level, the water gradually flows into the water tank 1, which helps to improve water cooling efficiency.

[0018] To improve the compatibility between the clamping mechanism 6 and the mold, the clamping mechanism 6 provided by this utility model includes a pair of mounting seats 62 arranged on the rotating groove 51. The mounting seats 62 are provided with key-shaped holes. A connecting pipe 63 communicating with the key-shaped holes is provided on one side of the mounting seats 62. A spring 64 is provided inside the connecting pipe 63. The two ends of the spring 64 are connected to the inner wall of the connecting pipe 63 and the end face of the baffle 66 by spot welding or by providing hook holes to hook the ends of the spring 64. A movable rod 65 is provided at the center of the spring 64. A baffle 66 is provided at one end of the movable rod 65, and a clamping plate 67 that cooperates with the clamping arm 61 is provided at the other end of the movable rod 65. The pair of mounting bases 62 provide two symmetrical key holes for mounting two clamping arms 61; the connecting tube 63 provides a guide for the movable rod 65. The clamping arms 61 are located between the clamping plate 67 and the key holes and can provide a counter-clamping force to the movable rod 65. Therefore, the two ends of the movable rod 65 are dynamically balanced by the counter-clamping force and the elastic force of the spring 64, thereby providing a range of motion for the clamping diameter of the pair of clamping arms 61 to clamp different molds.

[0019] Furthermore, the clamping arm 61 provided by this utility model includes a clamping shaft 611. Three clamping blocks 612, spaced 120 degrees apart, are provided on the portion of the clamping shaft 611 located between the inner ring plate 52 and the outer ring plate 53. An anti-loosening nut 613 is provided at the other end of the clamping shaft 611, located outside the mounting base 62. The spacing angle of the clamping blocks 612 allows for at least two line contact pairs with the mold. The paired clamping arms 61 provide four line contact pairs and form multiple pairs of V-shaped clamping openings, thereby improving the clamping performance of the clamping arms 61 on the mold. Simultaneously, the clamping blocks 612 and the anti-loosening nut 613 form an axial limit on the clamping shaft 611, preventing significant axial movement of the clamping arms 61 that would affect their clamping quality on the mold.

[0020] To improve the practicality of the transmission mechanism 4, the transmission mechanism 4 provided by this utility model includes a bevel gear transmission group 41, which includes a driving bevel gear and a driven bevel gear. The power input end of the bevel gear transmission group 41 is vertically downward and is mounted on a reduction gearbox 42. A pulley reducer 43 is installed inside the reduction gearbox 42, and a motor 44 is installed at the power input end of the pulley reducer 43. The pulley reducer 43 includes a driving pulley, a driven pulley, and a belt. The driving pulley is connected to the motor 44. The diameter of the driving pulley is smaller than that of the driven pulley, so the motor can reduce speed after inputting power to the pulley reducer 43. The pulley reducer 43 transmits power to the driving bevel gear through the axle of the driven pulley. The driving bevel gear is a small bevel gear, and the driven bevel gear is a large bevel gear. This achieves both power reversal and speed reduction, thereby providing effective power to the cantilever 2, enabling the cantilever 2 to drive the shaking and balancing mechanism 5 to achieve the corresponding shaking and water cooling purposes.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
