[0002] The blank positioning mechanism is an indispensable part of mold processing equipment. It is responsible for ensuring the precise position of the blank during the processing. The design and performance of the positioning mechanism are crucial for ensuring processing accuracy, improving production efficiency, and reducing the scrap rate.

[0003] However, in actual use, when the existing blank positioning mechanism for mold blank processing processes the blank, it is necessary to first clamp and fix it. It is fixed on the processing table by using a rack and slide, and then the blank to be processed is clamped by using the method of a slider and a bolt. However, when fixing the rack and slide, since a guide rail is provided on the processing table and a threaded groove is provided inside the guide rail, it can be fixed, but there is still a certain distance between each threaded groove. In this way, when the installed rack and slide clamp the blank, the rack and slide can only be installed at the position where the threaded groove is provided. Therefore, it has certain limitations in use. For this reason, we propose a blank positioning mechanism for mold blank processing. Summary of the Utility Model

[0031] Rack 6, the rack 6 is arranged inside the slide rail 3, and the rack 6 and the toothed plate 4 are meshed with each other;

[0032] Extrusion component 5, the extrusion component 5 is arranged inside the slide rail 3 and is used to control the meshing and separation of the rack 6 and the toothed plate 4.

[0033] The extrusion component 5 includes a wedge block 51 arranged inside the slide rail 3, an inclined block 57 is movably arranged on the inclined surface of the wedge block 51, the side surface of the inclined block 57 is arranged on the side surface of the rack 6, a guide post 53 is arranged on the top of the wedge block 51, a pull ring 55 is arranged at the top end of the guide post 53, inclined surfaces are arranged on both sides of the wedge block 51, and the arranged inclined surfaces correspond to the inclined surfaces of the inclined block 57, and the guide post 53 can be driven to move through the pull ring 55.

[0034] A through groove 56 is formed in the top of the sliding table 2. The inner part of the through groove 56 is movably arranged on the outer surfaces of the guide posts 53 and the pull rings 55. A connecting groove 54 is formed in the inner wall of the through groove 56. A clamping block 52 is arranged on the outer surface of the guide post 53. The outer surface of the clamping block 52 is movably arranged inside the connecting groove 54. The clamping block 52 can be stuck inside the through groove 56 through the connecting groove 54 and can drive the wedge block 51 to move.

[0035] A spring 58 is sleeved on the outer surface of the guide post 53. The two ends of the spring 58 are respectively arranged on the top of the wedge block 51 and the bottom of the sliding table 2. The spring 58 can play a role in resetting the wedge block 51.

[0036] A T-shaped groove 8 is formed in the inclined surface of the inclined block 57. A T-shaped block 7 is arranged on the inclined surface of the wedge block 51. The outer surface of the T-shaped block 7 is movably arranged inside the T-shaped groove 8. When the T-shaped block 7 moves, it can drive the inclined block 57 to move through the T-shaped groove 8, so that the rack 6 and the toothed plate 4 arranged on the side of the inclined block 57 are engaged with each other.

[0037] The top of the inclined block 57 is arranged at the inner groove of the slide rail 3. The contact parts between the inclined block 57 and the inside of the slide rail 3 are all provided with rounded corners.

The setting of the rounded corners can reduce the friction force.

[0038] When using this device, first, it is necessary to adjust the position of the sliding table 2. At this time, it is necessary to pull the pull ring 55 to drive the guide post 53 to move. The guide post 53 moves inside the through groove 56. At the same time, the guide post 53 drives the clamping block 52 arranged on its outer surface to slide inside the connecting groove 54, moving from the inside of the connecting groove 54 to the inner wall of the through groove 56, so that the guide post 53 drives the wedge block 51 arranged at the bottom end to rise. The wedge block 51 drives the T-shaped block 7 arranged on the inclined surface to move. At the same time, the T-shaped block 7 moves on the inner wall of the T-shaped groove 8 formed in the inclined surface of the inclined block 57. Therefore, it can drive the inclined block 57 to move. Therefore, the inclined block 57 drives the rack 6 arranged on the side to move away from the toothed plate 4, and can drive the sliding table 2 to be adjusted on the top of the workbench 1. When adjusted to the appropriate position, press the pull ring 55 to drive the guide post 53 arranged at the bottom to move, align the clamping block 52 arranged on the outer surface of the guide post 53 with the connecting groove 54. Therefore, it can drive the spring 58 to be compressed, and then drive the clamping block 52 to enter the bottom of the sliding table 2. The guide post 53 drives the wedge block 51 arranged at the bottom end to descend. The wedge block 51 drives the T-shaped block 7 arranged on the inclined surface to move. The T-shaped block 7 can drive the inclined block 57 to move. The inclined block 57 drives the rack 6 and the toothed plate 4 arranged on the side to be engaged, thus completing the adjustment of the sliding table 2.

A plurality of circular grooves 92 are formed on the side surface of the T-shaped block 7, and the sliding component 9 includes balls 91 movably arranged inside the plurality of circular grooves 92.

[0042] When the wedge block 51 moves, the wedge block 51 can drive the T-shaped block 7 with an inclined surface to move. The T-shaped block 7 moves along the inner wall of the T-shaped groove 8 formed on the inclined surface of the inclined block 57. At this time, the balls 91 provided on the side surface of the T-shaped block 7 are in contact with the inner wall of the T-shaped groove 8, reducing the friction between the T-shaped block 7 and the T-shaped groove 8 and preventing jamming.
