Description

Technical Field

[0001] This utility model relates to the field of punching die technology, specifically a punching die that facilitates material removal. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of objects by changing the physical state of the material being molded, and are often referred to as the "mother of industry".

[0003] In existing technology, punching operations are performed by mounting the punching die on an external press. During the punching process, the press moves downward to punch the punch and die, which leads to the following disadvantages: After the workpiece is punched, the inner wall of the punched part of the workpiece will be tightly attached to the outer wall of the punch, causing the workpiece to move upward with the punch, making it difficult to automatically unload the workpiece. This makes unloading the workpiece difficult and affects the subsequent workpiece punching process. At the same time, since manual intervention is required for unloading, it increases the workload of workers and poses safety risks. Therefore, it is necessary to improve the punching die to facilitate unloading and solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a punching die that facilitates material removal, thereby solving the problems mentioned in the background art.

[0025] Example 1:

[0026] Please see Figure 1-4 This utility model provides a technical solution: a punching die for easy material removal, including a base 1, a support frame 2 fixedly connected to the top of the base 1, a hydraulic cylinder 3 fixedly connected to the top of the support frame 2, a connecting plate 4 fixedly connected to the bottom of the hydraulic cylinder 3, a lower die 5 fixedly connected to the top of the base 1, a discharge pipe 6 fixedly connected to the inner side of the top of the base 1, an auxiliary punching mechanism 7 provided at the bottom of the connecting plate 4, and a movable discharge mechanism 8 provided on the back of the discharge pipe 6;

[0027] The auxiliary punching mechanism 7 includes a limiting punching component 71 and an auxiliary stripping component 72. The limiting punching component 71 is located at the bottom of the connecting plate 4, and the auxiliary stripping component 72 is located at the bottom of the connecting plate 4.

[0028] Furthermore, the limiting punching assembly 71 includes a connecting platform 711, which is fixedly connected to the bottom of the connecting plate 4. A bidirectional threaded rod 712 is rotatably connected inside the connecting platform 711. A limiting rod 715 is fixedly connected inside the connecting platform 711. A movable clamping plate 714 is slidably connected to the outside of the limiting rod 715. An accordion baffle 716 is fixedly connected to the outside of the movable clamping plate 714. A punching head 713 is provided on the inner side of the movable clamping plate 714, which facilitates the adjustment of the position of the movable clamping plate 714, thereby satisfying the clamping and limiting of the punching head 713, and facilitating the replacement and subsequent grinding operations by the staff.

[0029] Furthermore, the movable clamping plate 714 contacts the punching head 713, the movable clamping plate 714 is threadedly connected to the bidirectional threaded rod 712, and the movable clamping plate 714 is slidably connected to the connecting table 711, which facilitates a more stable operation.

[0030] Furthermore, the auxiliary stripping assembly 72 includes a spring 721, which is fixedly connected to the bottom of the connecting plate 4. A pressure plate 722 is fixedly connected to the bottom of the spring 721, and a slide rod 723 is fixedly connected to the top of the pressure plate 722. A connecting block 724 is fixedly connected to the top of the slide rod 723. This facilitates the pressing and limiting of the workpiece during punching, while preventing the punching head 713 from moving the workpiece after punching, thus facilitating stripping.

[0031] Furthermore, the connecting plate 4 has a groove at the corresponding position of the slide rod 723, and the slide rod 723 is slidably connected inside the groove, which makes the punching process more stable.

[0032] Example 2:

[0033] Based on Example 1, please refer to Figure 5 Furthermore, in conjunction with Embodiment 1, the movable discharge mechanism 8 includes a support plate 81, which is fixedly connected to the back of the discharge pipe 6. A limit plate 82 is fixedly connected to the top of the support plate 81, and a motor 83 is fixedly connected to the bottom of the support plate 81. The output end of the motor 83 extends through the support plate 81 to the outside and is fixedly connected to a rotating plate 84. A connecting rod 85 is rotatably connected to the top of the rotating plate 84. A slider 86 is slidably connected inside the limit plate 82, and a striking plate 87 is fixedly connected to the front of the slider 86 to facilitate the reciprocating motion of the striking plate 87, thereby satisfying the reciprocating striking of the discharge pipe 6 and preventing blockage.

[0034] Furthermore, the striking plate 87 contacts the discharge pipe 6, and the slider 86 and the connecting rod 85 are provided with grooves at corresponding positions, and the connecting rod 85 is rotatably connected inside the groove, which makes the discharge process more stable.

[0035] In actual operation, when this device is used, the threaded rod is first used as a T-type threaded rod to give it self-locking properties. The operator installs the device in the designated position, places the punch head 713 inside the movable clamping plate 714, and then uses tools such as a hex wrench to rotate the bidirectional threaded rod 712. The rotation of the bidirectional threaded rod 712, in conjunction with the limit rod 715, causes the movable clamping plate 714 to move until it contacts and clamps the punch head 713. The hydraulic cylinder 3 then operates to move the connecting plate 4, thereby causing the pressure plate 722 to engage with the lower mold 5. Contact is achieved through the movement of the pressure plate 722, which, in conjunction with the spring 721, causes the slide bar 723 to slide inside the connecting plate 4. This satisfies the need to hold and limit the workpiece during punching while preventing the punch head 713 from moving the workpiece after punching, thus facilitating material removal. The waste material from punching is discharged through the discharge pipe 6. The operation of the motor 83 causes the rotating plate 84 to rotate, which, in conjunction with the connecting rod 85, causes the slider 86 to slide inside the limiting plate 82. This enables the striking plate 87 to reciprocate back and forth, satisfying the need to reciprocate striking of the discharge pipe 6 and preventing blockage.
