[0025] like Figure 1-2 As shown, a plurality of inclined side hole synchronous punching mechanisms, an upper die and a lower die are arranged on the punch die, a positioning plate 100 is arranged on the lower die, and a lower template 200 adapted to the inner contour of the product is arranged on the positioning plate 100; the plurality of inclined side hole synchronous punching mechanisms include a plurality of side punch units 300 arranged on the periphery of the lower template 200, each side punch unit 300 includes a slide seat 10, a shaping member 20, a punch 30 and a driving seat 40, wherein:

[0026] Each slide seat 10 is detachably fixed on the positioning plate 100 and arranged on the outer side of the lower template 200, and the upper end thereof is provided with a first slide rail 11 extending obliquely toward the lower template 200;

[0027] Each shaping member 20 includes a support plate 21 and a pressing plate 22. The support plate 21 is embedded in the lower mold plate 200 and its outer contour is adapted to the inner contour of the product. The pressing plate 22 is arranged on the upper mold and matched to the side of the support plate 21. The lower end of the pressing plate 22 extends to the outer side of the upper mold and extends to the side of the support plate 21. Its lower end is adapted to the outer contour of the side wall of the product. The pressing plate 22 is provided with an inclined second slide groove 23, and each second slide groove 23 is adapted to a punch 30. When the mold is closed, the pressing plate 22 can move toward the product on the lower mold driven by the upper mold and press against its outer contour, and the lower mold plate 300 and the support plate 21 are against the inner surface of the product.

[0028] The punch 30 is obliquely mounted on the side of the pressing plate 22 and is elastically connected thereto. The punch 30 can slide along the second sliding groove 23 under the action of an external force.

[0029] Each driving seat 40 is arranged on the upper mold, including a positioning block 41 and a driving block 42. The positioning block 41 is fixed on the upper mold, and an inclined third slide rail 43 is provided at its lower end. The driving block 42 is slidably connected to the third slide rail 43. The lower end of the driving block 42 is adapted to the first slide rail 11 and can slide along it under the action of external force. One side wall of the driving block 42 is adapted to the punch 30; when the mold is closed, the positioning block 41 can push the driving block 42 to slide along the first slide rail 11 and the third slide rail 43 and approach the lower mold plate 200 under the drive of the upper mold, so as to push the punch 30 to slide on the second slide groove 23 and punch a side hole on the product.

[0030] The utility model provides a plurality of side punch units 300 on the periphery of the lower mold plate 200 of the lower mold, so that holes and grooves can be punched synchronously on different side walls of the product in one mold closing action, and the production efficiency is high; by arranging a slide seat 10 and a driving seat 40 on each side punch unit 300, and matching and arranging a plurality of inclined slideways / slideways thereon, a plurality of punches 30 can be pushed to move synchronously and tilted toward the side wall of the lower mold plate 200 under the mold closing pressure to punch the side wall of the product, and the punches 30 can be pulled out of the product and the pressure plate 22 by the rebound force of the elastic connecting part after the mold closing pressure is eliminated, so as to realize the synchronous punching of multiple inclined holes and grooves; by arranging the shaping part 20, the product can be pressed from the inner and outer sides of the product respectively before punching the side holes, so as to avoid or slow down the deformation of the product and achieve a high punching yield.

[0031] Further, such as Figure 1-2 As shown, an inclined first slide groove 24 is provided on the support plate 21 , the first slide groove 24 is adapted to the second slide groove 23 and is provided on its extension line, the first slide groove 24 runs through the support plate 21 , and a blanking trough 1 is provided on the positioning plate 100 directly below each first slide groove 24 .

[0032] It is understandable that the first chute 24 and the blanking chute 1 can collect or divert the waste cut by punching, so as to facilitate the timely separation of the waste and the product.

[0033] Furthermore, a third slide groove 44 and a fourth slide groove 45 are provided on the driving block 42. The third slide groove 44 is adapted to the first slide rail 11, and the fourth slide groove 45 is adapted to the third slide rail 43. The first slide rail 11 and the third slide groove 44 are both trapezoidal mechanisms, and a clearance groove 46 is provided at the bottom end of the third slide groove 44.

[0034] It can be understood that the first slide rail 11 and the third slide groove 44 of the trapezoidal structure have a relatively larger contact surface, so that the driving block 42 can slide more smoothly on the slide 10; the setting of the air avoidance groove 46 can avoid the formation of a vacuum between the driving block 42 and the slide 10 after the two are matched and contacted, ensuring that the driving block 42 and the slide 10 can smoothly contact, slide relatively and separate during the mold opening and closing process.

[0035] Furthermore, a first limit member 12 is provided on the slide seat 10 beside the first slide rail 11, and a first limit rod 47 adapted to the first limit member 12 is provided on the driving block 42; a second limit rod 48 extending toward the driving block 42 is also provided on the positioning block 41 beside the third slide rail 43, and a second limit member 49 adapted to the second limit rod 48 is provided on the driving block 42.

[0036] During the mold closing process, after the driving block 42 contacts the slide 10, it will slide on the first slide rail 11 and the third slide rail 43 under the continuous mold closing power. The first limit rod 47 can limit the relative displacement between the driving block 42 and the slide 10, and the second limit rod 48 can limit the relative displacement between the driving block 42 and the positioning block 41, ensuring that the driving block 42 is guided to move along the set path to push the punch 30 to accurately punch holes and grooves on the product.

[0037] As another preferred embodiment of the present invention, each punch 30 is obliquely mounted on the positioning plate 100 and located between the lower template 200 and a slide seat 10. Each punch 30 is elastically connected to the positioning plate 100 and can slide along the second slide groove 23 under the action of external force.

[0038] In application, the punch 30 can be arranged on the upper die or the lower die according to the actual structural layout of the mold, so that it can be fully pressed into the second slide groove 23 and the first slide groove 24 by the driving block 42 when the mold is fully closed, and pulled back to its original position by the elastic connecting part when the mold is opened.

[0039] Furthermore, the first slide rail 11 and the second slide groove 23 both extend obliquely downward toward the lower mold; the third slide rail 43 extends obliquely upward toward the upper mold.

[0040] It can be understood that the downwardly inclined first slide rail 11 and the second slide groove 23 can ensure that the driving block 42 can always move toward the lower mold plate 200 during the mold closing process and punch inclined side holes on the product; the upwardly inclined third slide rail 43 can cooperate with the first slide rail 11 to guide the position of the driving block 42 during the mold closing, so as to prevent it from moving forward smoothly and avoid position interference with the slide seat 10.

[0041] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
