Description

Technical Field

[0001] This utility model relates to the field of wax figure making, specifically a tool for rounding corners of wax models. Background Technology

[0002] In the wax model making process, rounding the corners of the wax model is an extremely important step, directly affecting the final quality of the wax model and the molding effect of the subsequent product. Whether in the field of precision casting, where wax models are used to manufacture complex parts, or in the jewelry industry, where exquisite wax model ornaments are created, precise and efficient corner rounding is indispensable.

[0003] Existing wax model rounding tools have a series of significant limitations in practical use. Firstly, regarding angle adjustment, most traditional tools are designed with a fixed angle, or their angle adjustment mechanisms are cumbersome and complex. When faced with wax model rounding requirements of different curvatures, operators find it difficult to quickly and accurately adjust the tool angle to meet the work requirements. Secondly, traditional tools are generally inconvenient to disassemble, and in actual production, the rounding cutter, as a consumable part, needs to be replaced regularly to ensure the rounding effect. However, the disassembly structure of traditional tools is poorly designed, the disassembly process is time-consuming and laborious, and may even damage other parts of the tool due to improper operation. Therefore, a wax model rounding tool needs to be designed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for rounding corners of wax molds to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wax mold rounding tool, comprising an arc-shaped cutting blade, an annular sliding plate fixedly mounted on the surface of the arc-shaped cutting blade, a damping slider slidably connected inside the annular sliding plate, a traction rod fixedly mounted on the surface of the damping slider, the front end of the traction rod penetrating the annular sliding plate and extending to the outside of the annular sliding plate, a rotating shaft fixedly mounted on one side of the traction rod through an opening, and a support rod rotatably connected to the surface of the rotating shaft through a bearing component.

[0006] Preferably, a sliding sleeve is slidably connected to the surface of the support rod, and abutment plates are fixedly installed on both sides of the top of the sliding sleeve. The top of the abutment plate is serrated, and rubber sleeves that cooperate with the abutment plates are fixedly installed on both sides of the surface of the rotating shaft.

[0007] Preferably, a support plate is fixedly installed between the two sides of the inner cavity of the sliding sleeve, a spring is welded to the top of the support plate, the top of the spring is welded to the top of the inner cavity of the support rod, and limiting sliding openings are provided on both sides of the support rod to cooperate with the support plate.

[0008] Preferably, the surface of the annular slide plate is provided with a sliding opening for use with the traction rod, and the left side of the bottom of the annular slide plate is provided with a movable opening for use with the traction rod.

[0009] Preferably, a handle is fixedly mounted on the surface of the sliding sleeve.

[0010] Preferably, a grip sleeve is fixedly installed below the surface of the support rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This wax model rounding tool allows you to pull the sliding sleeve downwards by holding the handle, causing the sliding sleeve to lower the support plate. After the support plate lowers, it is no longer in contact with the rubber sleeve. At this point, the support rod can be rotated via the pivot. After rotating to the appropriate angle, release the handle, causing the support plate to move upwards by the spring force. The rising support plate causes the sliding sleeve to rise, which in turn causes the support plate to rise. After the support plate rises, it can contact the rubber sleeve, thus limiting the rotation of the support rod. This allows for easy adjustment of the angle between the arc-shaped cutting blade and the support rod.

[0013] 2. This wax model rounding tool uses a horizontally pulled support rod to move a damping slider within an annular slide plate. After movement, the damping slider fits tightly against the inner wall of the annular slide plate, effectively limiting the movement of the support rod. When the arc-shaped cutting blade needs to be removed, the support rod can be pulled to move the damping slider to the leftmost position inside the annular slide plate. At this point, the traction rod can disengage the damping slider from the annular slide plate through the movable opening, facilitating the removal and replacement of the arc-shaped cutting blade.

[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 refer to Figure 1-5 As shown, this utility model provides a tool for rounding corners of wax molds, including an arc-shaped cutting blade 1. An annular slide plate 2 is fixedly installed on the surface of the arc-shaped cutting blade 1. A damping slider 3 is slidably connected inside the annular slide plate 2. A traction rod 4 is fixedly installed on the surface of the damping slider 3. The front end of the traction rod 4 passes through the annular slide plate 2 and extends to the outside of the annular slide plate 2. A rotating shaft 5 is fixedly installed on one side of the traction rod 4 through an opening. A support rod 8 is rotatably connected to the surface of the rotating shaft 5 through a bearing component.

[0023] Specifically, a sliding sleeve 9 is slidably connected to the surface of the support rod 8, a handle 14 is fixedly installed on the surface of the sliding sleeve 9, and abutment plates 10 are fixedly installed on both sides of the top of the sliding sleeve 9. The top of the abutment plates 10 is serrated. Rubber sleeves 11 that cooperate with the abutment plates 10 are fixedly installed on both sides of the surface of the rotating shaft 5. A support plate 12 is fixedly installed between the two sides of the inner cavity of the sliding sleeve 9, and a spring 13 is welded to the top of the support plate 12. The top of the spring 13 is welded to the top of the inner cavity of the support rod 8. Limiting sliding openings 15 that cooperate with the support plate 12 are opened on both sides of the support rod 8. By setting the abutment plates 1... 0, and pull down the sliding sleeve 9 through the handle 14, so that the sliding sleeve 9 drives the abutment 10 to descend. After the abutment 10 descends, it no longer contacts the rubber sleeve 11. At this time, the support rod 8 can be rotated through the rotating shaft 5. After rotating to a suitable angle, release the handle 14, so that the support plate 12 moves upward by the elastic force of the spring 13. The rise of the support plate 12 drives the sliding sleeve 9 to rise, and the rise of the sliding sleeve 9 drives the abutment 10 to rise. After the abutment 10 rises, it can contact the rubber sleeve 11 to limit the rotation of the support rod 8, thereby achieving the effect of facilitating the adjustment of the angle between the arc-shaped cutting knife 1 and the support rod 8.

[0024] Specifically, the surface of the annular slide plate 2 is provided with a sliding opening 6 for use with the traction rod 4, and the bottom left side of the annular slide plate 2 is provided with a movable opening 7 for use with the traction rod 4. A grip sleeve 16 is fixedly installed on the lower surface of the support rod 8. By setting the movable opening 7 and pulling the support rod 8, the support rod 8 drives the damping slider 3 to move inside the annular slide plate 2. After moving, the damping slider 3 can be tightly attached to the inner wall of the annular slide plate 2, achieving the effect of limiting the movement of the support rod 8. When it is necessary to remove the arc-shaped cutting knife 1, the support rod 8 can be pulled to move the support rod 8 to move the damping slider 3 to the leftmost side inside the annular slide plate 2. At this time, the traction rod 4 can disengage the damping slider 3 from the annular slide plate 2 through the movable opening 7, thereby facilitating the removal and replacement of the arc-shaped cutting knife 1.

[0025] Working Principle: This utility model is a tool for rounding corners on wax molds. By pulling down the sliding sleeve 9 through the handle 14, the sliding sleeve 9 causes the abutment plate 10 to descend. After the abutment plate 10 descends, it is no longer in contact with the rubber sleeve 11. At this time, the support rod 8 can be rotated through the rotating shaft 5. After rotating to a suitable angle, the handle 14 is released, causing the support plate 12 to move upward through the elastic force of the spring 13. The rising support plate 12 causes the sliding sleeve 9 to rise, which in turn causes the abutment plate 10 to rise. After the abutment plate 10 rises, it can contact the rubber sleeve 11, thus limiting the rotation of the support rod 8. This facilitates the cutting of the arc-shaped cutting blade 1 and the support rod 8. The angle can be adjusted so that when the position of the support rod 8 needs to be adjusted, the support rod 8 can be pulled laterally, causing the support rod 8 to move the damping slider 3 within the annular slide plate 2. After moving, the damping slider 3 can be tightly attached to the inner wall of the annular slide plate 2, achieving the effect of limiting the position of the moved support rod 8. When the arc-shaped cutting knife 1 needs to be removed, the support rod 8 can be pulled so that the support rod 8 moves the damping slider 3 to the leftmost position inside the annular slide plate 2. At this time, the traction rod 4 can disengage the damping slider 3 from the annular slide plate 2 through the movable port 7, thereby facilitating the removal and replacement of the arc-shaped cutting knife 1.
