Description

Technical Field

[0001] This utility model relates to the technical field of sand-shooting tank motion mechanism, and more specifically, it relates to a sand-shooting tank motion mechanism for a core shooter. Background Technology

[0002] Core shooters are specialized equipment used in the foundry industry for manufacturing sand cores, widely applied in the production of complex molds. They come in two types: hot core boxes and cold core boxes. Through simultaneous sand shooting, compaction, and heat curing processes, combined with high-temperature compressed air (200-260℃), they achieve efficient core making, producing high-precision sand cores. They are particularly widely used in the casting of automotive parts and other related fields. In the entire workflow of a core shooter, the sand shooting device not only accurately injects molding sand into the mold but also, through its precise control, ensures the filling density and compaction of the molding sand, providing a solid foundation for the subsequent heat curing process.

[0003] The existing lifting and horizontal movement mechanisms of sand-shooting tanks have some problems. Specifically, these mechanisms are relatively complex in structure, and the guiding mechanisms between each mechanism are relatively independent. It is difficult to make the independent lifting device stable. The higher the sand-shooting tank is raised, the less stable the guidance becomes. Under the radial force of the sand-shooting tank moving cylinder, it will wobble and cannot maintain positional accuracy. These problems may affect the operating efficiency of the core shooter and the forming quality of the sand core. Utility Model Content

[0004] This utility model provides a motion mechanism for the sand-shooting tank of a core shooter, which solves the technical problem in the related art that it is difficult to accurately control the relative position accuracy of the sand-shooting tank with other parts of the core shooter during the lifting and moving process.

[0005] This utility model provides a core shooter sandblasting tank motion mechanism, including a base and a sandblasting tank, with a column vertically installed on the base;

[0006] A lifting seat is slidably sleeved on the column so that the sandblasting tank is guided by the column and moves on the column to change the height position of the sandblasting tank.

[0007] The column slide is equipped with a top pressing component for moving the upper mold, and the base is provided with a displacement component that is corresponding to the upper mold and changes the horizontal position of the lower mold.

[0008] As a further optimization of this utility model, a movable cylinder is horizontally installed on the lifting base, and the driving end of the movable cylinder is fixedly connected to the sandblasting tank to change the horizontal position of the sandblasting tank.

[0009] As a further optimization of this utility model, a guide shaft is installed at the bottom of the sandblasting tank, and a guide block is installed on the lifting seat through which the guide shaft slides.

[0010] As a further optimization of this utility model, the top pressing component includes an upper worktable, a top plate, and an opening and closing cylinder. The top plate is assembled on the top of the column, and the upper mold is assembled on the bottom of the upper worktable. The upper worktable is slidably sleeved on the column and driven by the opening and closing cylinder to slide along the length of the column and change the position of the upper mold.

[0011] As a further optimization of this utility model, the opening and closing cylinder drive end is connected to the upper worktable via a connecting flange.

[0012] As a further optimization of this utility model, the displacement component includes a lower worktable and a guide rail. The guide rail is mounted on the base, and the lower mold is mounted on the lower worktable, with the lower worktable and the guide rail slidingly fitted together.

[0013] As a further optimization of this utility model, the lower worktable is slidably fitted with the guide rail via a slider.

[0014] As a further optimization of this utility model, a lifting mechanism for driving the lifting seat to move along the length of the column is installed on the base.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The sand-blasting tank motion mechanism of the core-shooting machine described in this utility model provides a unified guiding reference for the sand-blasting tank and the top pressure component, ensuring the relative position accuracy of each component during movement. The sand-blasting tank achieves precise adjustment of its height and horizontal position through the lifting seat and the moving cylinder. In conjunction with the top pressure component driving the upper mold to move stably along the column, and the displacement component driving the lower mold to slide smoothly along the guide rail, the sand-blasting tank and the upper and lower molds can be precisely aligned, avoiding the problem of uneven sand filling caused by positional deviation, and significantly improving the molding dimensional accuracy and compactness of the sand core.

[0017] 2. The sandblasting tank motion mechanism of the core shooting machine described in this utility model has a guide shaft at the bottom of the sandblasting tank that cooperates with the guide block of the lifting seat to effectively counteract the radial force borne by the moving cylinder and prevent the sandblasting tank from swaying when moving horizontally. The lower worktable slides with the guide rail through a slider to reduce frictional resistance and avoid jamming. The opening and closing cylinder is connected to the upper worktable through a connecting flange to ensure uniform transmission of driving force, thereby reducing component wear, reducing downtime caused by mechanical failure, and extending the overall service life of the equipment.

[0018] 3. The sandblasting tank motion mechanism of the core shooting machine described in this utility model allows the sandblasting tank to achieve multi-dimensional position adjustment through a lifting platform and a moving cylinder, adapting to the sandblasting requirements of molds of different specifications. The position adjustment of the upper and lower molds is achieved through the same column guide and guide rail sliding fit. The structure is compact and easy to operate, reducing the time for mold replacement and position calibration. In addition, the coordinated motion design of each component makes the sandblasting, mold closing and other processes smoother, effectively improving the overall operating efficiency of the core shooting machine.

[0033] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0034] like Figure 1 As shown in the embodiment of this utility model, a sandblasting tank motion mechanism for a core shooting machine includes a base 1 and a sandblasting tank 2, with a column 3 vertically installed on the base 1.

[0035] A lifting seat 6 is slidably sleeved on the column 3 so that the sandblasting tank 2 is guided by the column 3 and moves on the column 3 to change the height position of the sandblasting tank 2.

[0036] The column 3 is equipped with a top pressing part 4 for moving the upper mold, and the base 1 is provided with a displacement part 5 that is set to correspond to the upper mold and change the horizontal position of the lower mold.

[0037] The column 3 provides a unified guiding reference for the sandblasting tank 2 and the top pressure component 4, ensuring their positional accuracy during movement. By adjusting the height of the sandblasting tank 2 and the positions of the upper and lower molds, the sandblasting operation can be completed precisely, improving the quality of the sand core forming.

[0038] A movable cylinder 7 is horizontally mounted on the lifting platform 6. The drive end of the movable cylinder 7 is fixedly connected to the sandblasting tank 2 to change the horizontal position of the sandblasting tank 2.

[0039] A lifting mechanism 10 is installed on the base 1 to drive the lifting seat 6 to move along the length of the column 3. The lifting mechanism 10 is a hydraulic cylinder or an electric push rod. The lifting mechanism 10 provides a stable driving force for the lifting seat 6 and precisely controls the lifting height of the lifting seat 6, thereby accurately adjusting the height of the sandblasting tank 2 so that it is precisely matched with the mold position, ensuring accurate sandblasting position, improving sandblasting effect and sand core quality, and reducing manual operation error through automated drive.

[0040] The lifting platform 6 moves along the column 3, causing the sandblasting tank 2 to change its height. The moving cylinder 7 drives the sandblasting tank 2 to move horizontally, realizing the multi-position adjustment of the sandblasting tank 2 in space, meeting the needs of different sandblasting positions, enhancing the applicability of the equipment, and with a compact structure, reducing space occupation.

[0041] like Figure 3 As shown, a guide shaft 8 is installed at the bottom of the sandblasting tank 2, and a guide block 9 is installed on the lifting seat 6 through which the guide shaft 8 slides.

[0042] The guide shaft 8 cooperates with the guide block 9 to provide additional guidance for the horizontal movement of the sandblasting tank 2, reduce the radial force on the moving cylinder 7, prevent the sandblasting tank 2 from swaying when moving, ensure the stability and positional accuracy of its horizontal movement, and extend the service life of the moving cylinder 7.

[0043] like Figure 2 As shown, the top pressing component 4 includes an upper worktable 41, a top plate 42, and an opening and closing cylinder 43. The top plate 42 is mounted on the top of the column 3, and the upper mold is mounted on the bottom of the upper worktable 41. The upper worktable 41 is slidably sleeved on the column 3 and driven by the opening and closing cylinder 43 to slide along the length direction of the column 3 to change the position of the upper mold. The driving end of the opening and closing cylinder 43 is connected to the upper worktable 41 through a connecting flange 44.

[0044] The opening and closing cylinder 43 drives the upper worktable 41 to move along the column 3, precisely adjusting the height of the upper mold so that it can be precisely closed with the lower mold, ensuring the dimensional accuracy of the sand core forming. The column 3 guides and ensures the stable movement of the upper worktable 41, avoiding the upper mold offset from affecting the mold closing effect.

[0045] The connecting flange 44 enhances the connection between the opening and closing cylinder 43 and the upper worktable 41, making the driving force transmission more uniform, avoiding uneven force on the upper worktable 41 that could cause tilting, ensuring smooth and precise movement of the upper mold, and facilitating disassembly and maintenance.

[0046] Specifically, the displacement component 5 includes a lower worktable 51 and a guide rail 52. The guide rail 52 is mounted on the base 1, and the lower mold is mounted on the lower worktable 51. The lower worktable 51 and the guide rail 52 are slidably fitted together.

[0047] The lower worktable 51 slides along the guide rail 52, driving the lower mold to move horizontally, so as to align the lower mold with the upper mold and the sandblasting tank 2. The guide rail 52 guides and ensures that the lower mold moves smoothly, improves the accuracy of the lower mold position adjustment, facilitates the quick replacement of different lower molds, and improves work efficiency.

[0048] Furthermore, the lower worktable 51 is slidably engaged with the guide rail 52 via the slider 53.

[0049] The slider 53 reduces the friction between the lower worktable 51 and the guide rail 52, making the lower mold move more smoothly and effortlessly, reducing wear and extending the life of the parts. At the same time, the high precision of the slider 53 and the guide rail 52 further ensures the positional accuracy of the lower mold movement.

[0050] The base 1, lifting seat 6, upper worktable 41 and top plate 42 are assembled together by the column 3 to form a precise and stable structure.

[0051] The embodiments of the present utility model have been described above, but the present embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present embodiments, all of which are within the protection scope of the present embodiments.
