Description

Technical Field

[0001] This utility model relates to the field of grinding block cold press technology, specifically to a cold pressing workbench for a grinding block cold press. Background Technology

[0002] During grinding, grinding blocks are evenly installed on the substrate. The grinding blocks require manual material preparation. The raw materials are then placed on the worktable of a cold press and pressed together to form grinding blocks. However, the existing cold press worktable has a complex structure. It mainly relies on a through hole in the middle of the mold to fix the mold to the cold press and then cold press the raw materials. After cold pressing, the workpiece is ejected by the ejector pin. The process is complicated, making it inconvenient to demold the processed workpiece. Furthermore, during the cold pressing of the workpiece, the mold is squeezed and cracks outward, resulting in a short service life. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a cold pressing worktable for a grinding block cold press. It has a simple structure and is easy to operate. It can not only avoid damage to the external mold during processing and has a long service life, but also make it easier to unload the workpiece, providing convenience for users and effectively solving the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cold pressing worktable for a grinding block cold press, including a cold pressing mounting table. A lower support is fixedly provided on the lower surface of the cold pressing mounting table, and an upper and lower sliding seat is provided on the lower support. A through hole is provided in the middle of the cold pressing mounting table, and a cold pressing outer mold that can slide up and down is provided inside the through hole. Two cold pressing outer mold upper and lower driving components are provided on the upper surface of the upper and lower sliding seats to drive the cold pressing outer mold to slide up and down. A cold pressing mold core support is fixed on the upper surface of the upper and lower sliding seats. The upper end of the cold pressing mold core support is located inside the middle through groove of the cold pressing outer mold. When the upper and lower driving components control the cold pressing outer mold to be at its lowest position, the upper surface of the cold pressing outer mold is on the same plane as the upper end of the cold pressing mold core support. A screw jack is provided on the upper surface of the horizontal plate of the lower support to drive the upper and lower sliding seats to slide up and down. When the screw jack drives the upper and lower sliding seats to the highest position, the upper end of the cold pressing mold core support is level with the upper surface of the cold pressing mounting table, and the upper and lower movement stroke of the cold pressing mold core support is located inside the through hole of the cold pressing mounting table.

[0005] Furthermore, each side of the cold-press mounting platform is provided with a set of mounting holes, with no fewer than two mounting holes in each set. The device can be installed through the mounting holes, making installation more convenient.

[0006] Furthermore, the lower support includes a U-shaped seat, and sliding rails are provided on opposite sides of the two vertical plates of the U-shaped seat.

[0007] Furthermore, the cold-pressing outer mold upper and lower driving components include a telescopic cylinder fixed to the upper surface of the upper and lower sliding seats. The telescopic end of the telescopic cylinder is connected to a rotating top column through a hinge seat. The other end of the rotating top column is fixed to the lower surface of the cold-pressing outer mold through another hinge seat. By telescopically extending and retracting the telescopic cylinder, the lower end of the rotating top column can be moved, thereby adjusting the tilt angle of the rotating top column. By rotating the top column, the cold-pressing outer mold can be moved up and down, thereby adjusting the upper and lower position of the cold-pressing outer mold.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: The upper and lower sliding seats are moved downwards by a screw jack, which in turn moves the cold-pressing mold core support column downwards, positioning the upper end of the cold-pressing mold core support column inside the through hole of the cold-pressing mounting platform. Then, the extension and retraction of the telescopic cylinder moves the lower end of the rotating top column, thereby adjusting the tilt angle of the rotating top column. The rotating top column then moves the cold-pressing outer mold upwards, moving the upper end of the cold-pressing outer mold above the cold-pressing mold core support column, forming a cold-pressing groove at the upper middle part of the cold-pressing outer mold. The raw material is then placed inside the cold-pressing groove, and an external cold-pressing head presses the raw material inside the cold-pressing groove to form a grinding block. Upon completion of processing and demolding, the upper and lower sliding seats are moved downwards by a screw jack, which in turn moves the cold-pressing mold core support column downwards, aligning its upper end with the upper surface of the cold-pressing mounting table. The telescopic cylinder then extends and retracts, moving the lower end of the rotating top column to adjust its tilt angle. This rotating top column then slides the cold-pressing outer mold downwards, aligning its upper end with the upper end of the cold-pressing mold core support column, allowing the cold-pressed grinding block to be removed. The design is simple, easy to operate, and not only avoids damage to the outer mold during processing, resulting in a long service life, but also facilitates workpiece removal, providing convenience for users.

[0014] Please see Figure 1-3 This utility model provides a technical solution: a cold pressing worktable for a grinding block cold press, including a cold pressing mounting table 1. A lower support 3 is fixedly installed on the lower surface of the cold pressing mounting table 1, and an upper and lower sliding seat 5 is installed on the lower support 3. A through hole is provided in the middle of the cold pressing mounting table 1, and a cold pressing outer mold 6 that can slide up and down is provided inside the through hole. Two cold pressing outer mold upper and lower driving members 4 are provided on the upper surface of the upper and lower sliding seat 5 to drive the cold pressing outer mold 6 to slide up and down. A cold pressing mold core support column 7 is fixed on the upper surface of the upper and lower sliding seat 5. The upper end of the cold pressing mold core support column 7 is located inside the middle through groove of the cold pressing outer mold 6, and the upper surface of the cold pressing outer mold 6 when it is at its lowest position is aligned with the upper end of the cold pressing mold core support column 7. On the same plane, a screw jack 8 is provided on the upper surface of the horizontal plate of the lower support 3, which drives the upper and lower sliding seats 5 to slide up and down. When the screw jack 8 drives the upper and lower sliding seats 5 to the uppermost position, the upper end of the cold-pressed mold core support 7 is flush with the upper surface of the cold-pressed mounting platform 1, and the vertical movement stroke of the cold-pressed mold core support 7 is located inside the through hole of the cold-pressed mounting platform 1. The screw jack 8 drives the upper and lower sliding seats 5 to move downward, and the upper and lower sliding seats 5 drive the cold-pressed mold core support 7 to move downward. A set of mounting holes 2 is provided on both sides of the cold-pressed mounting platform 1, and the number of mounting holes 2 in each set is not less than two. The device can be installed through the mounting holes 2, making the installation more convenient. The lower support 3 includes a U-shaped seat 31. Sliding rails 32 are provided on opposite sides of the two vertical plates of the U-shaped base 31. The upper and lower driving components 4 of the cold pressing outer mold include a telescopic cylinder 43 fixed to the upper surface of the upper and lower sliding bases 5. The telescopic end of the telescopic cylinder 43 is connected to a rotating top column 41 through a hinge 42. The other end of the rotating top column 41 is fixed to the lower surface of the cold pressing outer mold 6 through another hinge 42. The telescopic cylinder 43 can move the lower end of the rotating top column 41 by telescopic extension and retraction, thereby adjusting the tilt angle of the rotating top column 41. The rotating top column 41 drives the cold pressing outer mold 6 to slide up and down, thereby adjusting the upper and lower position of the cold pressing outer mold 6. This grinding block cold pressing machine cold pressing worktable has a simple structure and is easy to operate. It can not only avoid damage to the outer mold during processing and has a long service life, but also makes it easier to unload the workpiece, providing convenience for users.

[0015] In use: The screw jack 8 drives the upper and lower sliding seats 5 to move downwards, which in turn drives the cold-pressing mold core support 7 to move downwards, so that the upper end of the cold-pressing mold core support 7 is located inside the through hole of the cold-pressing mounting table 1. During the cold pressing of the grinding block, the cold-pressing mounting table 1 protects the cold-pressing outer mold 6 to prevent it from breaking during cold pressing. The telescopic cylinder 43 extends and retracts, which drives the lower end of the rotating top column 41 to move, thereby adjusting the tilt angle of the rotating top column 41. The rotating top column 41 then drives the cold-pressing outer mold 6 to slide upwards, thus moving the upper end of the cold-pressing outer mold 6 above the cold-pressing mold core support 7, forming a cold-pressing groove in the upper middle part of the cold-pressing outer mold 6. The raw material is then placed inside the cold pressing tank, and then the external cold pressing head presses the raw material inside the cold pressing tank to form a grinding block, thus completing the processing. When demolding, the upper and lower sliding seats 5 are moved downward by the screw jack 8, and the upper and lower sliding seats 5 move the cold pressing mold core support 7 downward, so that the upper end of the cold pressing mold core support 7 is level with the upper surface of the cold pressing mounting table 1. Then, the extension and retraction of the telescopic cylinder 43 can drive the lower end of the rotating top column 41 to move, thereby adjusting the tilt angle of the rotating top column 41. By rotating the top column 41, the cold pressing outer mold 6 is moved downward, so that the upper end of the cold pressing outer mold 6 is level with the upper end of the cold pressing mold core support 7, thus removing the cold-pressed grinding block.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
