[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 1-6 As shown, the embodiments of this utility model include:

[0019] A plastic part punching device includes an injection molding machine 1, a robotic arm 2, a part-retrieving gripper 3, a punching fixture 4, a product mold base 5, a sliding servo mechanism 6, a primary punching station 7, a secondary punching station 8, a downward punching servo 9, a straight hole pagoda cutter 10, a lower-level punching servo 11, a stepped hole pagoda cutter 12, a product downward pressure limiting cylinder 13, and a reverse thrust plate 14. The injection molding machine 1 is equipped with the robotic arm 2, and the robotic arm 2 is equipped with the part-retrieving gripper 3, which is docked with the punching fixture 4. The punching fixture 4 is provided with several product mold bases 5 and is supported on the sliding servo mechanism 6. The product mold bases 5 pass through the primary punching station 7 and the secondary punching station 8. A straight hole pagoda cutter 10 driven by a downward punching servo 9 is matched directly above the primary punching station 7. A stepped hole pagoda cutter 12 driven by a lower punching servo 11 is matched directly below the secondary punching station 8. A reverse push plate 14 driven by a product downward limit cylinder 13 is mounted directly above the secondary punching station 8.

[0020] The sliding servo mechanism 6 consists of a linear guide 15 that supports the punching fixture 4 and a servo screw slide 16 that pulls the linear guide 15 in parallel. The linear guide 15 is connected to an external assembly line 17.

[0021] Furthermore, the punching fixture 4 is provided with a positioning bushing 18, and the pressing punching servo 9 is mounted on a frame 20 that integrates a synchronous lifting platform 19. The synchronous lifting platform 19 is provided with a pin 21 for docking with the positioning bushing 18.

[0022] Furthermore, the product retrieval gripper 3 is equipped with several product retrieval suction cups 22.

[0023] Furthermore, the robotic arm 2 is configured as an XYZ three-axis linear module.

[0024] This equipment is used to punch holes in the outer shell of injection molded parts and to process steps on the inner wall of the injection molded parts at the corresponding punching positions, ultimately forming three stepped holes of different sizes on one injection molded part.

[0025] First, the injection molding machine 1 produces the original product part. Then, the part pick-up gripper 3 picks up the original product part and transports it to the punching fixture 4 via the robot arm 2. The original product part is upside down on the product mold base 5 and then moved into the primary punching station 7 via the servo screw slide 16. At this station, the downward punching servo 9 drives the straight hole pagoda cutter 10 to process three straight holes of different sizes on the original product part. Then, the servo screw slide 16 transfers the semi-finished product to the secondary punching station 8. Since the original product part is upside down on the product mold base 5, the step processing is achieved by the lower punching servo 11 below the secondary punching station 8. The lower punching servo 11 is equipped with a step hole pagoda cutter 12, which is coaxially matched to the straight hole position. During the processing, the reverse push plate 14 directly above the secondary punching station 8 presses on the product to ensure that the product does not shift during the secondary punching process. The reverse push plate 14 is pressured by the product downward limit cylinder 13. The aforementioned pagoda-shaped cutter is a non-standard, custom-made cutter head with a three-section structure, used to form stepped holes of different sizes. After the secondary punching is completed, the sliding servo mechanism 6 carries the finished product out, and the finished product is manually placed into the production line 17 for delivery.

[0026] In summary, this utility model provides a plastic part punching equipment that constructs a linear processing path through a sliding servo mechanism 6, utilizes two punching stations to achieve straight hole forming and stepped forming respectively, and improves forming quality by using an inverted pagoda cutter in combination with a forward downward pressure according to process requirements, thereby replacing manual labor to achieve high-precision automated production.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
