Description

Technical Field

[0001] This utility model relates to the field of investment casting technology, specifically to a support for assembling and placing wax patterns in investment casting. Background Technology

[0002] In investment casting, after the welded wax model is made, it needs to be placed and dried. Currently, the common method is to vertically insert the support rod of the welded wax model into the socket of a fixed placement frame. However, due to the significant weight of the welded wax model, this vertical insertion and removal operation relies entirely on manual force to overcome gravity. This process has significant drawbacks: First, workers need to apply considerable downward force to insert the wax model and then exert considerable upward force to pull it out, making the operation extremely strenuous and labor-intensive. Second, during insertion and removal, friction and collision can easily occur between the wax model support rod and the fixed socket. Combined with the strenuous operation, precise control of the movements is difficult, easily causing damage to the welded wax model itself or the support rod, affecting the quality of the wax model and even leading to its scrapping. Furthermore, this laborious operation method also reduces work efficiency. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a support for assembling and placing wax models in investment casting.

[0004] This utility model is achieved through the following technical solution: a support bracket for placing welded wax models in investment casting is provided, including two parallel columns and multiple vertically arranged support beams. The two ends of the support beams are rotatably connected to the two columns respectively. One end of the support beam is equipped with a drive mechanism for driving the support beam to rotate. Multiple insertion tube assemblies are fixedly connected to the support beams. Each insertion tube assembly includes two insertion tubes arranged in a V-shape.

[0005] In this design, the two insertion tubes in the two insertion tube assemblies are arranged in an upward-opening V-shape. Therefore, the support rod of the welding wax model is inserted into the insertion tube to maintain a fixed position. When it is necessary to insert or remove the welding wax model, the drive mechanism drives the support beam to rotate, adjusting the insertion tube to a horizontal position, thus facilitating the insertion and removal of the welding wax model in the insertion tube. After insertion or removal, the support beam is rotated back to its initial position.

[0006] As an optimization, the two insertion tubes in the insertion tube assembly are staggered along the length of the support beam. This staggered arrangement prevents interference between the two support rods when the support rod for the welding wax mold is long.

[0007] As an optimization, the drive mechanism includes a worm gear fixed to the end of the support beam and a mounting bracket fixed to the column. A worm gear meshing with the worm gear is rotatably connected to the mounting bracket. In this design, the rotation of the worm gear is achieved by rotating the worm gear, thereby realizing the rotation of the support beam. Since the worm gear can achieve self-locking, the support beam can remain in a fixed state at all times.

[0008] As an optimization, a handwheel is fixedly connected to one end of the worm gear. In this design, the handwheel is used to manually rotate the worm gear.

[0009] As an optimization, a mounting plate is welded to the side of the column, and the mounting bracket is fixed to the mounting plate by bolts, with the bolt holes on the mounting bracket being vertical elongated holes. In this design, the vertical elongated holes allow for adjustment of the meshing between the worm gear and the worm, preventing poor meshing due to machining errors or long-term wear.

[0010] As an optimization, a top plate is welded to the side of the column above the mounting bracket, and a bolt that presses against the mounting bracket is threaded onto the top plate. In this design, the bolts press against the mounting bracket to prevent it from moving after the mounting bracket's position has been adjusted.

[0011] As an optimization, a base plate is welded to the lower end of the column, and a connecting beam is welded between the two columns. In this design, the base plate is supported on the ground, and the connecting beam achieves a stable connection between the two columns.

[0012] The beneficial effects of this utility model are as follows: The wax pattern placement bracket for investment casting of this utility model effectively solves the problems existing in the traditional vertical insertion and removal method through its unique rotating support beam and V-shaped insertion tube assembly design.

[0013] First, by driving the support beam to rotate through the drive mechanism, the insertion tube to be operated can be precisely adjusted to a horizontal state. At this time, the insertion tube changes from vertical to horizontal. The operator only needs to push and pull in the horizontal direction to easily complete the insertion and removal of the welding wax mold support rod, completely avoiding the strenuous operation of overcoming gravity in the vertical direction, significantly reducing the labor intensity of workers, and making the operation more labor-saving, smooth and easy to control.

[0014] Secondly, the labor-saving and horizontal operation significantly reduces the frictional resistance and risk of hard impact between the support rod and the insertion tube during the insertion and removal process, thereby effectively protecting the assembled wax mold body and the support rod, significantly reducing the probability of wax mold damage or deformation due to improper operation, and ensuring product quality.

[0015] Third, the support beam rotates under the drive of the worm gear transmission mechanism. This mechanism has reliable self-locking characteristics, which can ensure that the support beam can maintain its position stably at any angle without the need for additional locking devices. This provides a double guarantee for the stable placement and convenient operation of the welding wax mold.

[0016] The support structure is reasonably designed and easy to operate. The state can be switched by turning the handwheel. While saving labor and preventing damage, it also improves the efficiency of placing and picking up the wax molds for welding, and enhances the overall smoothness of the investment casting production line.

[0026] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0027] like Figures 1-7 As shown, this utility model discloses a welded wax model placement support for investment casting, comprising two parallel columns 1. The columns 1 are made of channel steel, with base plates 2 welded to their lower ends. The base plates 2 are fixed to the ground by expansion bolts, or can be placed directly on the ground for easy repositioning. Ribbing plates 3 are welded between the columns 1 and the base plates 2 for reinforcement.

[0028] A connecting beam 4 is welded between the two columns 1. The end of the connecting beam 4 is welded to the side of the bottom of the column 2, and a stable connection between the two columns 1 is achieved through the connecting beam 4.

[0029] It also includes multiple support beams 5 arranged vertically. The support beams 5 are set horizontally, and there are three vertically arranged. The two ends of the support beams 5 are respectively rotatably connected to two columns 1. In this embodiment, the support beams 5 are made of 60×60mm square steel. The two ends of the support beams 5 are welded with round shafts. The round shafts pass through the columns 1 and are rotatably connected to the columns 1 through the round shafts and the seated outer spherical bearings on the columns 1.

[0030] Multiple insertion tube assemblies are fixedly connected to the support beam 5, and these assemblies are evenly distributed along the length of the support beam 5. Figure 5 , 6 As shown, the insertion tube assembly includes two insertion tubes 6 arranged in a V-shape. Specifically, the two insertion tubes 6 in the insertion tube assembly are staggered along the length of the support beam 5 to prevent interference between the two support rods when the support rods for welding the wax mold are long. The two insertion tubes 6 are respectively welded to adjacent surfaces of the square steel of the support beam 5, so that the included angle is 90 degrees.

[0031] One end of the support beam 5 is equipped with a drive mechanism 7 that drives the support beam 5 to rotate, so the three drive mechanisms 7 drive their respective support beams 5 to rotate.

[0032] like Figure 2 As shown, the drive mechanism 7 includes a worm gear 71 fixed to the end of the support beam 5 and a mounting bracket 73 fixed to the column 1. The worm gear 71 is fixed to the end of the round shaft at the end of the support beam 5. A worm 72 that meshes with the worm gear 71 is rotatably connected to the mounting bracket 73. A handwheel 77 is fixed to one end of the worm 72, which is used to manually rotate the worm, thereby realizing the manual rotation of the support beam 5.

[0033] The mounting bracket 73 is located above the worm gear 71. To facilitate the installation of the mounting bracket 73, a mounting plate 74 is welded to the side of the column 1. The mounting bracket 73 is fixed to the mounting plate 74 by bolts, and the bolt holes on the mounting bracket 73 are vertical elongated holes. Thus, by adjusting the vertical position of the mounting bracket 73, the meshing of the worm gear and worm can be adjusted, preventing poor meshing due to machining errors or long-term wear.

[0034] A top plate 76 is welded to the side of the column 1 above the mounting bracket 73. A bolt 75 is threaded onto the top plate 76 and presses against the mounting bracket 73. The bolt presses against the mounting bracket to prevent the mounting bracket from moving after the mounting bracket position is adjusted.

[0035] How to use this utility model:

[0036] In normal conditions, the two insertion tubes 6 in the two insertion tube assemblies are arranged in an upward-opening V-shape, so the support rod of the welding wax mold 8 is inserted into the insertion tube 6 to maintain a fixed position.

[0037] When it is necessary to insert or remove the welding wax mold 8, turn the handwheel 77 to drive the worm gear 72 to rotate, which in turn drives the worm wheel 71 to rotate, causing the support beam 5 to rotate, thus adjusting the insertion tube 6 to be inserted or removed to a horizontal state. Figure 7As shown, the insertion tube 6 on the right is adjusted to a horizontal position to facilitate the insertion and removal of the welding wax mold 8 in the insertion tube 6. After insertion and removal, the support beam 5 is rotated to the initial position. Since the worm gear can achieve self-locking, the support beam 5 remains fixed.
