[0033] When an injection-molded workpiece is cast in a mold, surplus material is likely to remain at the joint between the mold frame and the injection-molded workpiece. This excess edge material is usually called a sprue. The sprue can affect the overall quality of the molded material and may have an adverse impact during subsequent assembly and processing. Therefore, the sprue at the corresponding position is usually cut off before the assembly of plastic products. In the prior art, the sprue of injection-molded workpieces is mostly cut manually, which increases the labor cost of enterprises. Moreover, the stability of manual operation is poor, the consistency of the products after cutting is not high, and the quality of the cut is difficult to guarantee. In most cases, it will also affect the assembly dimensions of the product itself.

[0034] The present utility model provides a punching device 100 to solve the above problems.

[0035] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, when an injection-molded workpiece is cast in a mold, surplus material is likely to remain at the joint between the mold frame and the injection-molded workpiece, which is generally called a sprue. In the prior art, the sprue of injection-molded workpieces is mostly cut manually or the injection-molded products are sent to a milling machine for cutting. Manual cutting increases the labor cost of enterprises, and the stability of manual operation is poor. The consistency of the products after cutting is not high, and the operation efficiency is also low. In order to ensure the cutting efficiency of the sprue and at the same time ensure the high quality of the cut of the material. In this embodiment, the fixing effect of the material is improved. Specifically, in the fixing structure, the receiving structure of the material is set as a plurality of profiling support blocks 3. The material is received by the plurality of profiling support blocks 3. When the upper surface of the material is pressed and fixed by the first pressing structure, the supporting surface can be fully attached to the material, so as to ensure the neatness of the cut after punching at the sprue position. It should be noted that the plurality of profiling support blocks 3 are of a split structure, which mainly supports the punching position and its position on the operating table 11 can be adjusted. In order to further ensure the cut quality of the sprue after punching, a second pressing structure is provided on the upper template 21 of the punching structure 2. The second pressing structure can move in the vertical direction along with the upper template 21. When the driving member drives the upper template 21 to move downward, the plurality of second pressing structures first contact and press the peripheral position of the sprue position of the material, and then the plurality of cutting tools 211 cut off the sprue of the material. During this process, one end of the plurality of cutting tools 211 moves to the inside of the blanking holes 31 on the plurality of profiling support blocks 3, so as to ensure the blanking of the punching position of the material. During this process, through the two pressing structures, the fixing effect of the material on the plurality of profiling support blocks 3 can be well ensured, and in the actual processing process, the punching quality of the punching position can be further improved.

[0036] A plurality of guide shafts 212 are provided at the four corner positions of the upper template 21. The plurality of guide shafts 212 are all slidably mounted on the upper end of the housing 1. In order to increase the guiding movement distance of the plurality of guide shafts 212 in the vertical direction as much as possible, in this embodiment, a mounting frame 111 fixedly connected thereto is provided on the workbench 11. The mounting frame 111 has four mounting shafts. The lower ends of the four mounting shafts are all fixedly connected to the workbench 11. The upper end of the mounting frame 111 is a plate body. A plurality of mounting holes (not shown in the figure) are provided on the plate body for mounting a plurality of guide cylinders 112. The plurality of guide cylinders 112 correspond to a plurality of through holes (not shown in the figure) on the housing 1. The plurality of guide shafts 212 are respectively inserted into the corresponding guide cylinders 112 and the inner sides of the through holes. After one end of the plurality of guide shafts 212 leaves the plurality of through holes, it can still slide in a guiding manner inside the plurality of guide cylinders 112, thereby effectively increasing the movement distance of the entire upper template 21 in the vertical direction.

[0037] Among them, as Figure 1 and Figure 2 shown, the first pressing structure is set as a plurality of cylinder fixing structures. Specifically, a plurality of cylinder members 4 are respectively arranged on the workbench 11 corresponding to the plurality of profiling support blocks 3. And a rotating shaft 41 is rotatably connected to one end of each of the plurality of cylinders. A first pressing plate 42 is provided at one end of the rotating shaft 41. In the actual use process, first, the materials are placed on the plurality of profiling support blocks 3, then the plurality of rotating shafts 41 are rotated to rotate the plurality of first pressing plates 42 to the positions directly above the plurality of profiling support blocks 3 respectively, and then the plurality of cylinders retract to drive the plurality of first pressing plates 42 to press and fix the materials. In the actual design process, the rotation of the rotating shaft 41 can be set as an automatic rotation structure. A motor structure can be provided at the output end of the cylinder to drive the first pressing plate 42 to rotate, so that the self-rotation of the first pressing plate 42 can be realized. After the punching and processing of the materials is completed, first, the cylinder moves upward to separate the first pressing plate 42 from the materials, and then the rotating shaft 41 rotates 90 degrees to facilitate the taking of the processed materials.

[0038] As Figure 1 , Figure 2 and Figure 4As shown, the second pressing structure is set as a follower structure that moves with the upper template 21. Specifically, the second pressing structure is set as a plurality of curved rod members 5. The curved rod member 5 includes a cross bar portion 52 and two vertical bar portions 51 respectively connected to both ends of the cross bar portion 52. A sliding connection in the vertical direction is formed between the two vertical bar portions 51 and the upper template 21. When the curved rod member 5 moves downward with the upper template 21, the second pressing plate 54 first contacts and presses the periphery of the gate position on the material. At this time, the spring 53 is compressed to apply a stable downward pressure, and the cutter 211 continues to move downward to punch the material. Since the position of the nut member 511 on the vertical bar portion 51 is adjustable, the force application degree of the spring 53 can also be adjusted accordingly. Specifically, it can be adjusted according to the actual situation.

[0039] In order to protect the material during the pressing process of the first pressing plate 42 and the second pressing plate 54 and prevent imprints from being formed on the surface of the material due to hard contact, in this embodiment, rubber blocks 6 are provided on one end surface of the first pressing plate 42 and the second pressing plate 54, and a plurality of the profiling support blocks 3 are also set as plastic parts, so as to ensure the appearance quality of the material after processing.

[0040] During the punching process, a certain amount of waste will be generated. In this embodiment, a corresponding collection structure is provided for centrally collecting the waste generated during the punching process. Specifically, the collection structure is arranged directly below the loading and unloading portion 113 of the workbench 11. The waste discharged through the discharge hole 31 is stored in the collection structure, which is convenient for subsequent processing.

[0041] Specifically, the collection structure mainly includes a collection box 7. The collection box 7 is placed inside the lower end of the housing 1. The waste after punching falls into the funnel structure 71 for centralized collection, and then falls into the collection box 7 through the discharge end of the funnel structure 71. When the waste in the collection box 7 is collected to a certain extent, the waste can be taken out for processing together with the entire collection box 7.

[0042] In this embodiment, the driving member is set as a pressing cylinder 22. The upper template 21 is directly driven by the pressing cylinder 22 to perform punching. Specifically, when the pressing cylinder 22 is installed, the pressing cylinder 22 is arranged at the upper end of the housing 1, and one end of the pressing cylinder 22 located inside the housing 1 is fixedly connected to the mounting frame 111. The stability of the pressing cylinder 22 after installation is ensured as much as possible through the two-layer installation structure. Of course, in addition to the above settings, the driving member can also be set as other electric driving structures, etc., which can be selected according to the actual situation.

[0043] One vertical end of the housing 1 is an operation end, and the operation end is open. To ensure safety during operation, a safety light curtain 8 is provided at the position of the operation end. During actual operation, if the operator's hand does not withdraw outward from the opening of the operation end, the pressing cylinder 22 will not press down the punching instruction by itself, thus ensuring the safety of the operator during operation.

[0044] As Figure 1 shown, a control panel 81 is provided on the housing 1. Generally, the working states of each driving structure can be displayed through the control panel 81, and double-start buttons 82 are provided on both sides of the housing 1 corresponding to the operation end. When controlling the pressing cylinder 22 to press down for punching, both of the start buttons need to be pressed simultaneously to execute the punching instruction. Further ensuring the safety during actual operation.

[0045] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
