[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] like Figures 1-4 As shown, the present invention provides a blanking mold for gasket processing, which is installed on a gasket processing equipment. It includes a left end plate 1, a right end plate 2, and a blanking plate 3 installed on the gasket processing equipment (not shown in the figure). The blanking plate 3 has a punching hole 31 and a blanking groove 32 connected to the punching hole 31. The left end plate 1 is fixedly connected to the blanking plate 3 by four first guide posts 4, and the right end plate 2 is fixedly connected to the blanking plate 3 by four second guide posts 5. The punching hole 31 provides punching space for the required material, and the blanking groove 32 provides a dropping function for the punched material.

[0030] Specifically, each of the four first guide posts 4 is equipped with a pressing assembly 6. The pressing assembly 6 includes a connecting plate 60 located on one side of the left end plate 1. A pressing cylinder 61 is mounted on the connecting plate 60. The output shaft of the pressing cylinder 61 slidably passes through the left end plate 1 and is fitted with an annular pressing block 62. A pressing plate 63 is fitted on the outer wall of the annular pressing block 62. The pressing plate 63 is slidably fitted on the four first guide posts 4. The annular pressing block 62 has a first opening 621 and a connection to the first opening 621. The connected pressing groove 622 has an annular pressing block 62 located on the outer edge of the pressing groove 622 with an annular protrusion 623. The inner wall of the first opening 621 extends with a first limiting ring 624, and a slidable pressing column 64 is provided in the first limiting ring. The first limiting ring 624 limits the pressing column 64. The pressing cylinder 61 drives the annular pressing block 62 to move left and right, thereby driving the pressing plate 63 to slide left and right on the first guide post 4, so as to realize the pressing column 64 pressing the material to be processed.

[0031] Specifically, a punching assembly 7 is provided on each of the four second guide posts 5. The punching assembly 7 includes a punching motor 71 installed on a gasket processing device (not shown in the figure). The output shaft of the punching motor 71 is sleeved with a punching eccentric block 72. One side of the punching eccentric block 72 abuts against one side of an abutment block 73. The other side of the abutment block 73 is fixedly connected to one end of a punching shaft 74. The other end of the punching shaft 74 is sleeved with an annular punching block 75. A punching plate 76 is sleeved on the outer wall of the annular punching block 75. The punching plate 76 is slidably sleeved on the four second guide posts 5. The annular punching block 75 can pass through the punching hole 31 and be accommodated in the pressure groove 62. Inside the ring-shaped punching block 75, there is a second opening 751. A second limiting ring 752 extends from the inner wall of the second opening 751. A slidable punching column 77 is provided inside the second limiting ring 752. The second limiting ring 752 limits the punching column 77. The punching motor 71 drives the punching eccentric block 72 to rotate. The punching eccentric block 72 eccentrically abuts against the abutting block 73, realizing the left and right movement of the abutting block 73. The abutting block 73 drives the punching shaft 74 and the punching block to move left and right, thereby driving the punching plate 76 to move left and right on the second guide post 5, thereby realizing the punching of the required material by the punching column 77.

[0032] More specifically, both the pressure column 64 and the punching column 77 are I-shaped. The pressure column 64 has a first limiting end 641 and a first pressing end 642. The first limiting end 641 is located on one side of the first limiting ring 624, and the first pressing end 642 is located on the other side of the first limiting ring 624. A first return spring 65 is also provided between the first pressing end 642 and the first limiting ring 624. The punching column 77 has a second limiting end 771 and a second pressing end 772. The second limiting end 771 is located on the second limiting end 642. On one side of ring 752, the second pressing end 772 is located on the other side of the second limiting ring 752. A second return spring 78 is also provided between the second pressing end 772 and the second limiting ring 752. Through the elastic contact between the first return spring 65 and the second return spring 78 and the pressing column 64 and the punching column 77, the initial contact of the material to be processed is achieved, and the material is fixed and positioned to prevent the material from deviating. This provides a stable punching operation for subsequent punching and improves the punching quality.

[0033] like Figure 5As shown, a receiving assembly 8 is also provided below the dropping plate 3 between the left end plate 1 and the right end plate 2. The receiving assembly 8 includes a gasket receiving net 81 and a waste receiving plate 82, which are fastened together from top to bottom between the left end plate 1 and the right end plate 2. Both the gasket receiving net 81 and the waste receiving plate 82 are arranged at an angle. The gasket receiving net 81 can be connected to an external gasket storage bin 100, and the waste receiving plate 82 can be connected to an external waste storage bin 200. The apertures on the feed mesh 81 can intercept the punched gaskets. The gaskets move along the inclined direction of the gasket receiving mesh 81 and fall into the external gasket receiving bin 100 connected to the gasket receiving mesh 81. The generated waste will fall through the apertures on the gasket receiving mesh 81 onto the waste receiving plate 82, and then move along the inclined direction of the waste receiving plate 82, finally falling into the external waste receiving bin 200, thereby realizing the automatic separation of gaskets and processing waste.

[0034] Specifically, a first guide sleeve 41 is fitted between the pressure plate 63 and the first guide post 4, and a third return spring 42 is fitted on the first guide post 4. The two ends of the third return spring 42 elastically abut against the first guide sleeve 41 and the blanking plate 3, respectively. A second guide sleeve 51 is fitted between the punching plate 76 and the second guide post 5, and a fourth return spring 52 is fitted on the second guide sleeve 51. The two ends of the fourth return spring 52 elastically abut against the second guide sleeve 51 and the blanking plate 3, respectively. The first guide sleeve 41 and the second guide sleeve 51 provide smooth guidance for the pressure plate 63 and the punching plate 76 on the first guide post 4 and the second guide post 5, respectively. The third return spring 42 provides a reset function for the pressure plate 63, and the fourth return spring 52 provides a reset function for the punching plate 76, thereby ensuring that the material to be punched is punched in a continuous line and improving the stability of the operation.

[0035] In addition, guide sleeves are provided between the left end plate 1 and the output shaft of the pressing cylinder 61, and between the right end plate 2 and the punching shaft 74, to provide good guidance and stability for the operation of the output shaft of the pressing cylinder 61 and the punching shaft 74.

[0036] Working principle:

[0037] In operation, the material to be processed is first placed on one side of the discharge plate 3 via an external conveying device or manually. Then, the pressing cylinder 61 is activated, and its output shaft pushes the annular pressing block 62 and the pressing plate 63 to move to the right along the first guide post 4, pressing the material firmly onto the discharge plate 3. During the pressing process, the pressing column 64 applies pressure to the material under the action of the first return spring 65, ensuring that the material is firmly pressed.

[0038] After the material is pressed, the punching motor 71 is started. The punching motor 71 drives the punching eccentric block 72 to rotate. The punching eccentric block 72 pushes the abutment block 73 and the punching column 77 to move to the left, so that the annular punching block 75 passes through the punching hole 31 to punch the material. During the punching process, the punching column applies pressure to the material under the action of the second return spring 78. At the same time, it works with the pressing column 64 to firmly press a center circle of the material, providing stability for subsequent punching work and improving the quality after punching.

[0039] The punched gaskets fall into the gasket collection net 81 through the drop chute 32, while the waste material falls into the waste collection plate 82 through the gasket collection net 81 and is finally collected by the corresponding external gasket and waste collection bin.

[0040] After the material is ejected, the ejection motor 71 continues to rotate. Under the action of the fourth return spring 52, the ejection plate 76 and the annular ejection block 75 move to the right along the second guide post 5 to reset. At the same time, the pressing cylinder 61 and the third return spring 42 drive the annular pressing block 62 and the pressing plate 63 to move to the left along the first guide post 4 to reset, completing one material dropping cycle.

[0041] 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 based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
