[0005] Furthermore, a positioning plate, a spring and a connecting rod are arranged on the lower die, wherein the tail end of the outer sliding block presses against the positioning plate, the tail end of the outer sliding block is connected to the connecting rod, and a spring is arranged on the connecting rod.

[0006] Furthermore, a positioning block is provided on the lower mold, and three positioning blocks are provided around the center of the lower mold for placing the ventilation holes on the peripheral sides of the positioning blocks.

[0007] Furthermore, there are three inner sliding blocks, which are arranged around the center of the upper mold, and are arranged within a circumscribed circle formed by the three positioning blocks.

[0008] Furthermore, the upper die is provided with an upper guide column, and the lower die is provided with a lower die guide seat, and the upper guide column and the lower die guide seat are slidably matched.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model utilizes a plurality of outer slides and an inner slide to cooperate with each other, and forms a plurality of punching holes by pressing down at one time, thus avoiding the problem that traditional punching holes need to be punched multiple times, improving production efficiency, achieving high product consistency, increasing efficiency by 5 times, and making operation convenient and safe.

DETAILED DESCRIPTION

[0018] like Figure 1 As shown, a vent 10 claw processing mold includes an upper mold and a lower mold, wherein the upper mold is provided with an upper mold wedge 2, and the lower mold is provided with an outer slider 5 and an inner slider 6. The outer slider 5 and the inner slider 6 are arranged on the same guide rail, wherein the front end of the outer slider 5 is provided with a groove 51, and the front end of the inner slider 6 is provided with a protrusion 61, the groove 51 and the protrusion 61 are matched in shape, and the upper mold wedge 2 is connected to the tail end of the outer slider 5 through a bevel.

[0019] like Figure 2 As shown, a positioning plate 91, a spring 7, and a connecting rod 8 are provided on the lower mold, wherein the tail end of the outer slider 5 presses against the positioning plate 91, the tail end of the outer slider 5 is connected to the connecting rod 8, and the spring 7 is provided on the connecting rod 8.

[0020] Furthermore, a positioning block 94 is also provided on the lower mold. Three positioning blocks 94 are provided around the center of the lower mold for placing the ventilation holes on the peripheral side of the positioning blocks 94 .

[0021] Furthermore, there are three inner slide blocks 6 , which are arranged around the center of the upper mold, and are arranged within a circumscribed circle formed by the three positioning blocks 94 .

[0022] Furthermore, the upper die is provided with an upper guide column 1 , and the lower die is provided with a lower die guide seat 3 , and the upper guide column 1 is slidably matched with the lower die guide seat 3 .

[0023] The working steps of the equipment of the utility model are:

[0024] Step 1, the press is at the upper limit point, and the mechanism is in standby mode;

[0025] Step 2, such as Figure 3-5As shown, the vent 10 is placed on the side of the positioning block 94;

[0026] Step 3, such as Figure 6 As shown, the press is started, and the press descends. The upper die wedge 22 begins to insert into the outer slider 5. At this time, the inner and outer sliders 5 begin to approach the product. During the continued descent, the inner slider 6 and the outer slider 5 contact the vent 10. At this time, the outer slider 5 stops moving, and the inner slider 6 continues to slide. The protrusion 61 pierces the product and contacts the groove 51 of the outer slider 5. When the press descends to the lowest position, the shape of the vent 10 is pressed out.

[0027] Step 4, as the press machine runs through a stroke, the press machine returns to the upper limit point, at which time the spring 7 pulls out the outer slider 5, completes the reset state, takes out the processed vent 10, and the processing of the vent 10 is completed.

[0028] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
