Description

Technical Field

[0001] This utility model belongs to the field of casting technology, and in particular relates to a casting box for machine tool parts. Background Technology

[0002] Sand casting molds (casting boxes) are tools used to make sand molds. They play a role in filling and fixing the slurry into a specific shape during the sand casting process. They are important tools for achieving accurate shape and stable dimensions during sand casting and are widely used in the casting industry. When using a casting box, sand needs to be put into the casting box, compacted, and then the sand on the surface of the casting box needs to be scraped flat. The patent with publication number CN216607127U discloses a sand mixing mold leveling device for precision casting sand mold casting. When using it, the leveling device needs to be placed on top of the mold to level it. However, for each mold made, the height of the entire top frame and its components needs to be manually adjusted, which is not only time-consuming and labor-intensive, but also cumbersome and not conducive to efficient operation. Furthermore, patent CN222020620U discloses a casting box for sand casting. Through the cooperation of support columns, springs, adjusting nuts, and scrapers, the height of the scraper can be adjusted by rotating the adjusting nut to adjust the spring force when making each mold. Although this technology is an improvement over the technology of patent CN216607127U, the scraper has the ability to move perpendicular to the direction of movement due to the presence of springs during the process of leveling the sand on the surface of the casting box. When the sand distribution is not uniform, the scraper will be pushed vertically by the sand, resulting in uneven sand leveling and affecting the casting effect. Therefore, the existing sand leveling structure of the casting box needs to be improved. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing a casting box for machine tool parts, thereby solving the problems of inconvenient scraper adjustment and easy deviation during the scraping process in the prior art.

[0004] In view of this, the present invention provides a casting box for machine tool parts, including a box body; The main frame is slidably mounted on the box along the first direction. When the main frame is at the initial position of the sliding trajectory, it can rotate relative to the box. The mounting bracket is slidably mounted on the main frame in the second direction, and a scraper is connected to the side of the mounting bracket near the box. The adjustment mechanism includes an adjustment screw, a threaded hole, and two locking nuts. The threaded hole is located on the main frame. The threaded end of the adjustment screw is threadedly engaged with the threaded hole and rotatably connected to the mounting bracket. The two locking nuts are spaced apart on the adjustment screw and are located at opposite ends of the threaded hole.

[0005] In this technical solution, after sand is placed into the box, the main frame is flipped to the top of the box from its initial position. The height of the scraper is adjusted by rotating the adjusting screw. After the height adjustment is completed, the adjusting screw is locked by two locking nuts to restrict its rotation. At this time, the main frame is manually pushed so that the main frame, along with the mounting bracket and scraper, moves back and forth on the box in the first direction. During this process, the scraper stably scrapes the sand. After the sand is scraped, the main frame returns to its initial position. The main frame is then flipped so that the main frame, mounting bracket, scraper, and adjusting mechanism all come to the side of the box without affecting its normal use.

[0006] In the above technical solution, the main frame is further provided with two sets of guide columns, and the mounting frame is provided with two sets of guide sleeves. The two sets of guide columns are slidably sleeved in the two sets of guide sleeves along the second direction.

[0007] In the above technical solution, two sets of sliding grooves are symmetrically arranged on the two opposite side walls of the box body. A flip groove is provided on the side wall at one end of the sliding groove. Sliding frames are provided at both ends of the main frame. The two sliding frames are slidably arranged in the two sets of sliding grooves along the first direction. When the sliding frame is in the flip groove, it can flip relative to the box body. When the sliding frame is in the sliding groove, the flipping of the sliding frame is restricted.

[0008] In the above technical solution, at least one sliding frame is detachably connected to the main frame.

[0009] In the above technical solution, a further step is to provide an abutment seat on the side wall of the box body near the initial position of the main frame, so that the main frame can abut against the abutment seat after it is flipped in the initial position.

[0010] Furthermore, in the above technical solution, the adjusting screw can be adjusted manually.

[0011] Furthermore, in the above technical solution, handles are provided on the main frame.

[0012] The beneficial effects of this utility model are: 1. The scraper height can be precisely adjusted by the cooperation of the main frame, mounting bracket, adjusting screw, and threaded hole. During the adjustment process, the worker does not need to bear the weight of the device, which is more labor-saving. After the height is adjusted, it is fixed by two locking nuts to prevent the scraper from shifting during the leveling process and improve the leveling accuracy.

[0013] 2. The main frame has a flip-up design, which facilitates the filling and cleaning of the sand box and improves the ease of operation.

[0014] 3. The abutment seat provides stable support for the main frame and its components, and also limits the rotation angle of the main frame to prevent excessive rotation from damaging the structure.

[0015] 4. The adjusting screw is designed for manual adjustment, and the main frame is applied force through the handle, making it easy for workers to operate. Attached Figure Description

[0024] In the description of this utility model, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0025] Example 1 like Figures 1-5 As shown, this embodiment provides a casting box for machine tool parts, including a box body 1, a main frame 2, a mounting bracket 3, a scraper 4, and an adjustment mechanism 5; Please see Figures 1-3 Box 1 is a cuboid structure with a receiving groove on the top. The receiving groove is used to hold sand. For ease of description and understanding, according to the orientation order in the attached figure, the opening direction of the receiving groove is defined as the vertical direction, and the opening direction perpendicular to the receiving groove is defined as the horizontal direction. The main frame 2 is slidably mounted on the housing 1 along the first direction X. In this embodiment, the first direction X is perpendicular to the opening direction of the receiving groove, i.e., the horizontal direction. When the main frame 2 is in the initial position of the sliding trajectory, it can flip relative to the housing 1. Figure 1 This shows a schematic diagram of the main frame 2 in its initial position; For details, please refer to Figure 1 and Figure 3 Two sets of sliding grooves 101 are symmetrically arranged on the two opposite side walls of the housing 1. A flip groove 102 is provided on the side wall of one end of the sliding groove 101. The flip groove 102 is located on the upper side wall of the sliding groove 101. The main frame 2 is U-shaped in general. Sliding frames 7 are provided at both ends of the main frame 2. The two sliding frames 7 are slidably arranged in the two sets of sliding grooves 101 along the first direction X. The cross-section of the end of the sliding frame 7 located in the sliding groove 101 is rectangular. The minimum width of the flip groove 102 is greater than the maximum width of the cross-section of the end of the sliding frame 7. Therefore, when the sliding frame 7 is located in the flip groove 102, it can flip relative to the housing 1, thereby ensuring that after the sand is leveled, the main frame 2 and its components can be flipped to the side of the housing 1, avoiding affecting the subsequent use of the housing 1; please refer to Figure 2The width of the sliding groove 101 in the vertical direction is matched with the width of the sliding frame 7 in the vertical direction when it is not flipped. Therefore, when the sliding frame 7 is located in the sliding groove 101, the flipping of the sliding frame 7 is restricted, thereby ensuring the stability of the scraper 4 during the leveling process. Mounting bracket 3 is slidably mounted on main frame 2 along the second direction Y. A scraper 4 is connected to the side of mounting bracket 3 near housing 1. The scraper 4 is detachably connected to mounting bracket 3. In this embodiment, the second direction Y changes as main frame 2 is rotated. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 When the main frame 2 and its components are located above the housing 1, the second direction Y is the vertical direction. Please refer to [link / reference]. Figure 3 When the main frame 2 and its components are rotated 90 degrees and located on the side of the box 1, the second direction Y is horizontal. The adjustment mechanism 5 includes an adjustment screw 501, a threaded hole, and two locking nuts 502. The threaded hole is located in the middle of the main frame 2 and passes through two surfaces of the main frame 2 located in the second direction Y. After the threaded end of the adjustment screw 501 is threadedly engaged with the threaded hole, it is rotatably connected to the mounting bracket 3. The two locking nuts 502 are spaced on the adjustment screw 501 and are located at both ends of the threaded hole. The two locking nuts 502 can contact the two surfaces of the main frame 2 located in the second direction Y respectively. In this embodiment, when it is necessary to adjust the position of the scraper 4 in the second direction Y, first rotate the two locking nuts 502 in a direction away from each other so that both locking nuts 502 are separated from the main frame 2. At this time, rotating the adjusting screw 501 can adjust the position of the scraper 4 in the second direction Y. After the adjustment is completed, rotate the two locking nuts 502 in a direction closer to each other so that the two locking nuts 502 abut against the two surfaces of the main frame 2 respectively, restricting the spiral movement of the adjusting screw 501 and ensuring that the scraper 4 will not deviate during the scraping process. In this embodiment, the rotation drive of the adjusting screw 501 and the two locking nuts 502 can be driven by a tool, such as a wrench, or can be adjusted manually, which is convenient for workers to operate. In this embodiment, after sand is placed into the box 1, the main frame 2 is flipped to the top of the box 1 from the initial position. The height of the scraper 4 is adjusted by rotating the adjusting screw 501. After the height adjustment is completed, the adjusting screw 501 is locked by two locking nuts 502 to restrict the rotation of the adjusting screw 501. At this time, the main frame 2 is manually pushed so that the main frame 2, along with the mounting bracket 3 and the scraper 4, moves back and forth on the box 1 along the first direction X. During this process, the scraper 4 stably scrapes the sand. After the scraping is completed, the main frame 2 returns to the initial position. The main frame 2 is flipped so that the main frame 2, the mounting bracket 3, the scraper 4, and the adjusting mechanism 5 all come to the side of the box 1, without affecting the normal use of the box 1.

[0026] Example 2 Based on Embodiment 1, this embodiment also discloses a structure in which the mounting bracket 3 slides relative to the main frame 2; In this embodiment, please refer to Figure 5 The main frame 2 is provided with two sets of guide columns 601, which are located on both sides of the adjusting screw 501. The mounting frame 3 is provided with two sets of guide sleeves 602, which are positioned opposite to the two sets of guide columns 601. The surface of the guide sleeve 602 near the guide column 601 is provided with a groove. The two sets of guide columns 601 are slidably sleeved in the two sets of grooves along the second direction Y. During the adjustment of the scraper 4 position, the mounting bracket 3 drives the two sets of guide columns 601 to slide in the two sets of grooves respectively, ensuring that the scraper 4 moves strictly in the second direction Y.

[0027] Example 3 Based on Embodiment 1, this embodiment also discloses a method for connecting the sliding frame 7 to the main frame 2; In this embodiment, please refer to Figures 1-4 At least one sliding frame 7 is detachably connected to the main frame 2, which facilitates the assembly and disassembly of the main frame 2 and the two sliding frames 7 from the housing 1, thereby facilitating the maintenance and replacement of the main frame 2. In the first case, where a sliding frame 7 is detachably connected to the main frame 2, when the main frame 2 needs to be installed onto the box 1, first insert the sliding frame 7 at one end of the main frame 2 into a set of sliding grooves 101, then insert the movable sliding frame 7 into another set of sliding grooves 101, and then connect the movable sliding frame 7 to the other end of the main frame 2 to complete the assembly of the main frame 2 and the two sliding frames 7 with the box 1. In the second case, when both sliding frames 7 are detachably connected to the main frame 2, and the main frame 2 needs to be installed onto the box 1, first install the first sliding frame 7 at one end of the main frame 2, and then repeat the operation method of the first case to complete the assembly of the main frame 2 and the two sliding frames 7 with the box 1. When it is necessary to remove the main frame 2 from the housing 1, a sliding bracket 7 is detached from the main frame 2, and the main frame 2 can be removed from the housing 1. In this embodiment, the sliding frame 7 and the main frame 2 can be connected by threaded fasteners.

[0028] Example 4 Based on Example 1, this embodiment further optimizes the structure of the housing 1; In this embodiment, please refer to Figure 4A stop seat 8 is provided on the side wall of the box body 1 near the initial position of the main frame 2. After the main frame 2 is flipped in the initial position, it can abut against the stop seat 8. In this way, the stop seat 8 can provide stable support for the main frame 2 and its components, and can also limit the flipping angle of the main frame 2 to avoid excessive flipping and damage to the structure. In this embodiment, the connection between the abutment seat 8 and the housing 1 can be achieved by using threaded fasteners.

[0029] Example 5 Based on Example 1, this embodiment further optimizes the structure of the main frame 2; In this embodiment, please refer to Figure 1 or Figure 2 or Figure 4 The main frame 2 is equipped with a handle 9. Workers can apply force through the handle 9 to drive the main frame 2 and its components to slide back and forth in the first direction X, and drive the main frame 2 and its components to flip at the initial position.
