Description

Technical Field

[0001] The utility model relates to the technical field of mold production, in particular to a mold cutting table. Background Art

[0002] A mold is a tool used to make molded objects. It mainly realizes the processing of the object's shape by changing the physical state of the molded material. During the stamping process of the mold, the blank is generally placed on the lower die base, and then the upper die base is used to stamp the lower die base accordingly, so that the blank is pressed and formed in the mold cavity to realize the production and processing of the mold. However, during the stamping process, the size of the blank directly affects the quality of the mold for pressing and forming. When the size of the blank is too large, it is easy to cause waste of the blank, and the excess edge material needs to be sheared later. If the size of the blank is too small, it is easy to cause the edges and corners of the mold for pressing and forming to be missing, resulting in quality defects. Therefore, the cutting process of the blank is particularly important.

[0003] Chinese patent application number CN202221945520.6 discloses a mold cutting mechanism. The utility model has a simple structure and is easy to operate. By arranging multiple cutting blades in the cutting box, the multiple cutting blades correspond to the cutting grooves set on the cutting table, so that the multiple cutting blades cut the blank at the same time, and the blank can be cut into multiple finished blanks at one time, with high cutting efficiency.

[0004] The mold cutting mechanism in the above patent is also used to cut the mold, and has the function of cutting the blank into multiple finished blanks at one time. However, its cutting structure is fixed and the spacing between two adjacent groups of cutting blades cannot be adjusted according to actual use requirements, and thus blanks of different specifications cannot be cut. There are obvious usage defects, so we need to propose a mold cutting table. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1-6 The utility model provides a mold cutting table, including a workbench 1, a placement slot 2 is opened on the top of the workbench 1, and a tightening assembly is fixedly installed on both sides of the workbench 1. The tightening assembly includes an electric push rod 17 fixedly installed on the surface of the mounting plate 14, and the telescopic end of the electric push rod 17 is rotatably connected to the tightening plate 18. One end of the tightening plate 18 extends to the top of the workbench 1, and also includes a rubber tightening block 19. The rubber tightening block 19 is installed at the bottom of the tightening plate 18.

[0025] By using the placement groove 2 and the clamping assembly in combination, the mold blank can be fixed on the top of the workbench 1. Before cutting, the user can place the blank in the inner cavity of the placement groove 2, and then the user can rotate the clamping plate 18 to rotate one end of the clamping plate 18 to the top of the mold blank. Then the user can open the electric push rod 17 through the external controller, and the telescopic end of the electric push rod 17 will drive the clamping plate 18 to move downward to clamp the mold blank in the inner cavity of the placement groove 2. By setting the rubber clamping block 19, it can be avoided that the clamping plate 18 directly contacts the mold blank and causes the surface of the mold blank to be scratched.

[0026] Preferably, a gantry 3 is provided on the top of the workbench 1, and an adjustable cutting assembly is installed at the bottom of the gantry 3. Lifting cylinders 4 are fixedly installed on both sides of the top of the gantry 3. The telescopic end of the lifting cylinder 4 passes through the gantry 3 and extends to the inner cavity of the gantry 3 and is fixedly connected to the top of the adjustable cutting assembly. The adjustable cutting assembly includes a fixed frame 5 fixedly installed on the telescopic end of the lifting cylinder 4, and a driving motor 6 is fixedly installed on one side of the fixed frame 5. The output shaft of the driving motor 6 passes through the fixed frame 5 and extends to the inner cavity of the fixed frame 5 and is fixedly installed with a rotating rod 7. The end of the rotating rod 7 away from the driving motor 6 is rotatably connected to the inner wall of the fixed frame 5, and a plurality of cutting blades 8 are provided on the surface of the rotating rod 7.

[0027] After the mold blank is fixed on the workbench 1, the user can turn on the lifting cylinder 4 through the external controller. After the lifting cylinder 4 is connected to the external air source, its telescopic end will push the fixing frame 5 downward to drive the cutting blade 8 to move downward so that the bottom of the cutting blade 8 contacts the surface of the mold blank. Then the user can turn on the driving motor 6 through the external controller. The output shaft of the driving motor 6 will drive the cutting blade 8 to rotate through the rotating rod 7 to cut the mold blank.

[0028] Among them, the cutting blade 8 is fixed to the surface of the rotating rod 7 through an adjustable positioning assembly. The adjustable positioning assembly includes a positioning tube 9 that is slidably connected to the surface of the rotating rod 7. The inner wall of the positioning tube 9 is slidably connected to the surface of the rotating rod 7. The surface of the positioning tube 9 is threadedly connected with a positioning rod 10. One end of the positioning rod 10 passes through the positioning tube 9 and extends to the inner cavity of the positioning tube 9 to fit with the surface of the rotating rod 7. It also includes a scale line 13, and the scale line 13 is opened on one side of the rotating rod 7.

[0029] Through the setting of the adjustable positioning component, when the spacing between the cutting blades 8 needs to be adjusted to cut out mold blanks of different sizes, the user can loosen the positioning rod 10 and move the positioning tube 9 and the cutting blade 8. The user can judge the moving distance through the scale line 13, and then adjust the spacing between the two adjacent groups of cutting blades 8. After the adjustment is completed, the user can tighten the positioning rod 10 to lock the position of the positioning tube 9 and the cutting blade 8.

[0030] It is worth noting that a limiting assembly is also provided between the positioning tube 9 and the rotating rod 7. The limiting assembly includes a limiting rod 11 fixedly installed on one side of the inner cavity of the positioning tube 9. A limiting groove 12 adapted to the limiting rod 11 is provided on one side of the rotating rod 7. The surface of the limiting rod 11 is slidably connected to the inner wall of the limiting groove 12.

[0031] By setting the limiting component, the stability of the cutting blade 8 can be improved to ensure that the cutting blade 8 can rotate with the rotating rod 7. When adjusting the installation position of the cutting blade 8, the movement of the positioning tube 9 will drive the limiting rod 11 on its inner wall to slide in the inner cavity of the limiting groove 12 on the surface of the rotating rod 7.

[0032] Furthermore, moving components for moving the gantry 3 to its use position are installed on both sides of the workbench 1. The moving components include mounting plates 14 fixedly installed on both sides of the workbench 1. Two groups of electric slides 15 are fixedly installed on the inner sides of the two groups of mounting plates 14.

The two ends of the gantry 3 are fixedly connected to the top of the two groups of slides 16 respectively.

[0033] Through the setting of the moving component, during the cutting process, the user can open the electric slide 15 through the external controller. The operation of the electric slide 15 can drive the gantry 3 to move through the slide 16 on its top, and then drive the adjustable cutting component to move, so that it can cut the mold blank during the movement.
