DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] See also Figure 1 and Figure 2 The utility model provides a multi-point punching device for plastic product molding, including a workbench 1, a bracket 2 is fixed on the top of the workbench 1 by bolts, the bracket 2 plays a role of supporting and fixing a machine table 3 fixed on the top by bolts, a puncher 4 connected to the machine table 3, so that by moving the puncher 4, a punching knife 41 assembled at the bottom of the puncher 4 can be translated in multiple directions, the punching knife 41 is rotated by the driving of the puncher 4, and the rotating punching knife 41 can be driven by the downward movement of the puncher 4 to perform a punching operation on the plastic product placed on the workbench 1, and a dust cover structure 5 is arranged at the bottom of the puncher 4.

[0023] See also Figure 2 , Figure 3 and Figure 4The utility model provides a multi-point punching device for plastic product molding. The dust cover structure 5 includes a fixed sleeve 51, which is fixed to the bottom of the punch 4 by bolts, and the punching knife 41 is located in the fixed sleeve 51. Guide grooves 52 are provided at both ends of the fixed sleeve 51. A slider 53 sliding along the inner wall of the guide groove 52 is arranged at the inner upper end of the pressing sleeve 54. The inner shape of the slider 53 is equipped with a rotatably connected pulley 531, and the pulley 531 is against the inner wall of the guide groove 52 to achieve the flexibility of the slider 53. A movable positioning rod 532 penetrating the bottom of the fixed sleeve 51 is fixed at the bottom of the slider 53. The positioning rod 532 is slidably connected to the fixed sleeve 51 in a vertical state through the pressing sleeve 54, which is used to position the pressing sleeve 54 and reduce the friction between the slider 53 and the inner wall of the guide groove 52. The upper end of the fixed sleeve 51 is equipped with a first rotating rod 55. The left and right ends of the first rotating rod 55 are fixed with torsion springs 56, and the first rotating rod 55 is fixed with a torsion spring 56. The torsion spring 56 is rotatably connected to the fixed sleeve 51, and a second rotating rod 57 rotatably connected is provided on the top of the slider 53. The first rotating rod 55 is rotatably connected to the second rotating rod 57, and a second torsion spring 571 is installed at the connection. One end of the second torsion spring 571 is fixed to the first rotating rod 55, and the other end is fixed to the second rotating rod 57. Under the action of the second torsion spring 571, when the first rotating rod 55 and the second rotating rod 57 are in a natural state, the connection between the first rotating rod 55 and the second rotating rod 57 protrudes outward to prevent the pressing sleeve 54 from being resisted by the first rotating rod 55 and the second rotating rod 57 when sliding. The upper end of the rear side of the fixed sleeve 51 is integrally formed with a dust removal pipe 58 connected thereto, and the dust removal pipe of the dust removal equipment matched with the punching device is plugged into the dust removal pipe 58. When the pressing sleeve 54 is in a natural state, the bottom end of the pressing sleeve 54 is higher than the bottom end of the punching knife 41, so that when the punching operation is performed, the pressing sleeve 54 will first press on the surface of the plastic product;

[0024] When the punch 4 pushes the punching knife 41 to move downward and punches the plastic product on the workbench 1, it will push the fixing sleeve 51 and the pressing sleeve 54 together. Since the bottom end of the pressing sleeve 54 is higher than the bottom end of the punching knife 41, the pressing sleeve 54 will press on the surface of the plastic product. By pressing the pressing sleeve 54 on the surface of the plastic product, the plastic product can also be pressed and positioned, effectively avoiding the problem of plastic product deviation during the punching process. When the punching knife 41 continues to move downward, the pressing sleeve 54 will push the slider 53, so that The slider 53 slides upward along the inner wall of the guide groove 52. At the same time, the first rotating rod 55 and the second rotating rod 57 will be forced to rotate outward. At this time, the torsion spring 56 will be deformed under the force to generate elastic force. Then the pressing sleeve 54 will cover the punching place of the plastic product. When punching, the dust removal equipment will be turned on. Then, the dust removal pipe will be connected to the dust removal pipe 58, and the internal area of ​​the pressing sleeve 54 will be extracted, so as to realize all-round extraction of plastic debris and dust during the punching operation, effectively avoiding the problem of incomplete dust removal.
