Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a wax-type tree group model structure with the effect of reducing air bubbles. Background Technology

[0002] A wax tree model typically consists of multiple wax parts or models connected to a main rod in a specific way. These wax models are usually the shape of the final product to be cast, which may be various complex mechanical parts, handicrafts, or jewelry. The connection method between the wax models and the wax tree is carefully designed to ensure that the wax models maintain a stable position during subsequent shell making, firing, and pouring processes, and that the molten metal can smoothly fill the space occupied by each wax model. The shape and layout of the entire wax tree model structure are optimized according to factors such as the characteristics of the casting product, process requirements, and production efficiency. For example, for wax models with similar shapes or small sizes, a multi-layered arrangement or symmetrical distribution may be used to make full use of space and improve production efficiency. This wax tree model structure is a key intermediate product in the investment casting process, and its quality and structural rationality have a significant impact on the quality and cost of the final cast product.

[0003] Currently available wax tree models may generate air bubbles during molding, which can affect the quality of subsequent metal casting. In view of this, we propose a wax tree model structure that reduces air bubbles to solve the above problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wax-shaped tree model structure with a bubble-reducing effect, solving the problems mentioned in the background section. To achieve the above objectives, this utility model is implemented through the following technical solution: A wax-shaped tree model structure with a bubble-reducing effect includes a worktable, a vibration table mounted on the top of the worktable, a mold fixedly connected to the top of the vibration table, a wax inlet fixedly connected to the middle of the mold, a rotating vibration mechanism at the bottom of the vibration table, a striking mechanism at the top of the vibration table, a motor fixedly connected to the top of the worktable, a telescopic rod fixedly connected to the inner wall of the worktable, a mold base fixedly connected to the top of the telescopic rod, and the rotating vibration mechanism including a fixed sleeve and a sliding rod.

[0005] Preferably, the fixed sleeve is fixedly connected to the inner wall of the workbench, and the sliding rod is slidably connected to the inner wall of the fixed sleeve.

[0006] Preferably, the rotary vibration mechanism includes a fixed frame, a pulley, and an arc-shaped block.

[0012] (1) This utility model achieves the ability of the mold to rotate during casting by cooperating with the worktable, vibration table, mold, wax inlet, rotating vibration mechanism, fixed sleeve, sliding rod, fixed frame, pulley, and arc block. The wax liquid inside the mold can be vibrated by the impact of the pulley and arc block. The rotational vibration can promote the rise and discharge of air bubbles in the wax liquid, thereby reducing the porosity and defects in the finished product, improving the quality and surface smoothness of the wax mold, and helping the wax liquid to fill more evenly in the mold, avoiding the occurrence of local thick or thin walls, and ensuring the dimensional accuracy and structural integrity of the wax mold.

[0013] (2) This utility model can further strike the mold by cooperating with the striking mechanism, the trigger rod, the mounting frame, the pull rope, the fixed inclined frame, the fixed wheel, the connecting rope, the gravity block, the motor, the telescopic rod and the mold base. The vibration generated by the striking can further promote the rapid rise and discharge of the air bubbles hidden in the wax liquid, reduce the air holes in the wax mold and improve the density and surface quality of the wax mold.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1-4As shown, a wax tree model structure with bubble-reducing effect includes a worktable 1, a vibration table 2 mounted on the top of the worktable 1, a mold 3 fixedly connected to the top of the vibration table 2, a wax inlet 4 fixedly connected to the middle of the mold 3, a rotary vibration mechanism 5 at the bottom of the vibration table 2, a striking mechanism 6 at the top of the vibration table 2, a motor 7 fixedly connected to the top of the worktable 1, a telescopic rod 8 fixedly connected to the inner wall of the worktable 1, a mold base 9 fixedly connected to the top of the telescopic rod 8, and the rotary vibration mechanism 5 including a fixing sleeve 50. The sliding rod 502 and the fixed sleeve 501 are fixedly connected to the inner wall of the workbench 1. The sliding rod 502 is slidably connected to the inner wall of the fixed sleeve 501. The rotary vibration mechanism 5 includes a fixed frame 503, a pulley 504, and an arc block 505. The fixed frame 503 is fixedly connected to the bottom of the sliding rod 502. The pulley 504 is rotatably connected to the inner wall of the fixed frame 503. The arc block 505 is fixedly connected to the top of the workbench 1. The top of the telescopic rod 8 is fixedly connected to the output end of the motor 7. The surface of the pulley 504 is in contact with the top of the workbench 1. The arc-shaped block 505 is located on the movement trajectory of the pulley 504. The motor 7 drives the telescopic rod 8 to rotate, which in turn drives the mold base 9 to rotate. The mold base 9 drives the vibration table 2 to rotate, which in turn drives the sliding rod 502 to rotate. The sliding rod 502 drives the fixed frame 503 and the pulley 504 to rotate and move along the top of the worktable 1. When the pulley 504 rotates and moves, it collides with the surface of the arc-shaped block 505, causing the pulley 504 to push the sliding rod 502 up along the inner wall of the fixed sleeve 501. When the top of the fixed frame 503 collides with the top of the vibrating table 2, the vibrating table 2 causes the mold 3 to move upward. When the pulley 504 passes the arc block 505, the vibrating table 2 falls down, thereby reciprocating to vibrate the wax liquid inside the mold 3, causing the air bubbles in the wax liquid to rise and be discharged, thereby reducing the porosity and defects in the finished product, improving the quality and surface smoothness of the wax model, and helping the wax liquid to fill more evenly in the mold, avoiding the occurrence of local thick or thin walls, and ensuring the dimensional accuracy and structural integrity of the wax model.

[0023] Example 2

[0024] Please see Figures 1-4As shown, the striking mechanism 6 includes an actuating rod 601, a mounting bracket 602, and a pull rope 603. The mounting bracket 602 is fixedly connected to the top of the vibration table 2. The actuating rod 601 is rotatably connected to the inner wall of the mounting bracket 602. The pull rope 603 is fixedly connected to the end of the actuating rod 601 away from the sliding rod 502. The striking mechanism 6 also includes a fixed inclined frame 604, a fixed wheel 605, a connecting rope 606, and a gravity block 607. The fixed inclined frame 604 is fixedly connected to the front of the vibration table 2. The fixed wheel 605 is fixedly connected to the end of the fixed inclined frame 604 away from the vibration table 2. The connecting rope 606 is installed on the surface of the fixed wheel 605. The gravity block 607 is fixedly connected to the end of the connecting rope 606 near the mold 3. The actuating rod 601 is located at the sliding rod 502. On the movement trajectory of 2, the end of the connecting rope 606 near the vibration table 2 is fixedly connected to the pull rope 603. The mold 3 is located on the movement trajectory of the gravity block 607. When the sliding rod 502 is lifted, it collides with the trigger rod 601, causing the trigger rod 601 to rotate and tilt along the inner wall of the mounting frame 602. The trigger rod 601 drives the pull rope 603 to pull down, and the pull rope 603 drives the connecting rope 606 to pull down, causing the connecting rope 606 to pull the gravity block 607 up. When the trigger rod 601 returns to its original position, the gravity block 607 will strike the surface of the mold 3, thereby realizing the striking vibration of the mold 3. This can further promote the rapid rise and discharge of the air bubbles hidden in the wax liquid, reduce the porosity in the wax mold, and improve the density and surface quality of the wax mold.

[0025] This utility model discloses a wax-type tree assembly structure with a bubble-reducing effect. In use, the operator pours molten wax into the mold 3 through the wax inlet 4. The motor 7 is then started, causing the telescopic rod 8 to rotate. The telescopic rod 8 rotates the mold base 9, which in turn rotates the vibration table 2. The vibration table 2 then rotates the sliding rod 502, which in turn rotates the fixed frame 503 and pulley 504 along the top of the worktable 1. During rotation, the pulley 504 collides with the surface of the arc-shaped block 505, causing it to lift the sliding rod 502 along the inner wall of the fixed sleeve 501. When the top of the fixed frame 503 collides with the top of the vibration table 2, the vibration table 2 moves the mold 3 upwards. When the pulley 504 passes the arc-shaped block 505, the vibration table 2 falls, thus achieving reciprocating motion of the wax inside the mold 3. The wax is vibrated, causing air bubbles in the wax to rise and be expelled, thereby reducing porosity and defects in the finished product, improving the quality and surface finish of the wax model, and helping the wax to fill the mold more evenly, avoiding local thick or thin walls, and ensuring the dimensional accuracy and structural integrity of the wax model. At the same time, when the sliding rod 502 is lifted, it collides with the trigger rod 601, causing the trigger rod 601 to rotate and tilt along the inner wall of the mounting frame 602. The trigger rod 601 drives the pull rope 603 to pull down, and the pull rope 603 drives the connecting rope 606 to pull the gravity block 607 up. When the trigger rod 601 returns to its original position, the gravity block 607 will strike the surface of the mold 3, thereby realizing the striking vibration of the mold 3, which can further promote the rapid rise and expulsion of hidden air bubbles in the wax, reduce porosity in the wax model, and improve the density and surface quality of the wax model.

Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model.
