Description

Technical Field

[0001] This utility model belongs to the field of stamping dies, and specifically relates to a stamping die for a heat-bearing mesh. Background Technology

[0002] The main function of the sintering mesh is to support and protect electronic components during the high-temperature sintering process. It primarily serves to support and protect electronic components, ensuring that they do not directly contact the high-temperature equipment during sintering, thus preventing damage. During manufacturing, the four sides of the sintering mesh need to be bent to seal the edges and improve its strength.

[0003] In the existing technology, when bending and sealing the wire mesh, it is necessary to use a stamping device to stamp and seal each side in sequence, which results in low stamping and sealing efficiency of the wire mesh. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a stamping mold for heat-bearing mesh to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a stamping die for a heat-bearing mesh, including an upper die base and a lower die base. A lower die intermediate positioning block is fixedly installed on the top surface of the lower die base. A lower die bending slider is slidably installed on the top surface of the lower die base on all four sides of the lower die intermediate positioning block. A guide wedge is fixedly installed on the top of the lower die bending slider.

[0007] The bottom surface of the upper die base is equipped with an upper die intermediate punch. Each of the four sides of the upper die intermediate punch is provided with an upper die oblique cutting punch that is fixedly installed on the bottom surface of the upper die base. The upper die oblique cutting punch can push the corresponding guide wedge below inward when pressed down.

[0008] Furthermore, a positioning seat located outside the lower die bending slider is fixedly installed on the top surface of the lower die base. A spring telescopic shaft is installed on the positioning seat, and the telescopic end of the spring telescopic shaft is fixedly connected to the outer end of the lower die bending slider.

[0009] Furthermore, a cylinder is fixedly installed on the top surface of the upper mold base, and the telescopic end of the cylinder slides through the upper mold base and extends to the bottom surface of the upper mold base;

[0010] The upper die intermediate punch includes a lifting main punch and multiple oblique sliding bending blocks. The lifting main punch is fixedly connected to the telescopic end of the cylinder. The multiple oblique sliding bending blocks are arranged around the outer ring of the lifting main punch, and the multiple oblique sliding bending blocks are slidably installed on the bottom surface of the upper die base. The lifting main punch and the multiple oblique sliding bending blocks of the outer ring are slidably connected by oblique snap-fit ​​guide grooves.

[0011] Furthermore, eight oblique sliding bending blocks are provided.

[0012] Furthermore, the upper die has 12 oblique cutting punches.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, lower die bending sliders with guide wedges are provided around the lower die center positioning block, and upper die oblique cutting punches corresponding to the guide wedges are provided on the upper die base. When the upper die base moves downward, it drives the upper die center punch and the upper die oblique cutting punch to move downward synchronously. At this time, the upper die center punch cooperates with the lower die center positioning block to clamp and fix the sintering mesh, while the downward moving upper die oblique cutting punch can move the guide wedges inward to drive the four lower die bending sliders on the four sides of the lower die center positioning block to slide inward synchronously. Then, the four sliding lower die bending sliders simultaneously punch and bend the four sides of the sintering mesh upward, so as to complete the punching and sealing process of the four sides of the sintering mesh at the same time, thereby improving the punching and sealing efficiency of the sintering mesh.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0024] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0025] Please see Figures 1-5 As shown, this utility model is a stamping die for a heat-bearing mesh, including an upper die base 1 and a lower die base 3. A lower die intermediate positioning block 4 is fixedly installed on the top surface of the lower die base 3. A lower die bending slider 5 is slidably installed on the top surface of the lower die base 3 on all four sides of the lower die intermediate positioning block 4. A guide wedge 6 is fixedly installed at the top of the lower die bending slider 5. An upper die intermediate punch 9 is installed on the bottom surface of the upper die base 1. An upper die oblique cutting punch 10 is fixedly installed on the bottom surface of the upper die base 1 on all four sides of the upper die intermediate punch 9. The upper die oblique cutting punch 10 can push the corresponding guide wedge 6 below it inward when it is pressed down.

[0026] The upper die base 1 is provided with two layers of stamping lifting plates, and the two layers of stamping lifting plates are connected by a hydraulic telescopic shaft. The upper die middle punch 9 is fixedly installed on the bottom surface of the lower stamping lifting plate, and the upper die oblique cutting punch 10 is fixedly installed on the bottom surface of the upper stamping lifting plate and slides through to extend below the lower stamping lifting plate. There are 12 upper die oblique cutting punches 10, and the 12 upper die oblique cutting punches 10 are evenly distributed on the upper die middle punch 9.

[0027] When stamping and sealing the edges of the sintering mesh 100, the sintering mesh 100 is first placed upright on the top surface of the lower die center positioning block 4. Then, the upper die base 1 drives the upper die center punch 9 and the upper die oblique cutting punch 10 to move down synchronously. Then, the upper die center punch 9 first abuts against the top surface of the sintering mesh 100 and cooperates with the lower die center positioning block 4 to clamp and fix the sintering mesh 100. Then, as the upper die base 1 continues to move down, the upper die base 1 drives the upper stamping lifting plate and the upper die oblique cutting punch 10 to continue to move down, while the lower stamping lifting plate and the upper die center punch 9 remain at the same height. The moving upper die oblique cutting punch 10 can move the guide wedge block 6 inward to abut against it, so as to drive the four lower die bending sliders 5 on the four sides of the lower die center positioning block 4 to slide inward synchronously. Then, through the four sliding lower die bending sliders 5, the four sides of the sintering mesh 100 are simultaneously stamped and bent upward to complete the stamping and sealing process of the four sides of the sintering mesh 100 at the same time.

[0028] Specifically, a positioning seat 7 located outside the lower die bending slider 5 is fixedly installed on the top surface of the lower die base 3. A spring telescopic shaft 8 is installed on the positioning seat 7. The telescopic end of the spring telescopic shaft 8 is fixedly connected to the outer end of the lower die bending slider 5. When the upper die base 1 moves upward to reset, causing the upper die oblique cutting punch 10 to separate from the guide wedge block 6, the lower die bending slider 5 can automatically move and reset towards the positioning seat 7 under the elastic tension of the spring telescopic shaft 8. At the same time, the lower die releases its clamping of the heat-bearing mesh 100.

[0029] Specifically, a cylinder 2 is fixedly installed on the top surface of the upper mold base 1. The telescopic end of the cylinder 2 slides through the upper mold base 1 and extends to the bottom surface of the upper mold base 1. The upper mold intermediate punch 9 includes a lifting main punch 91 and multiple oblique sliding bending blocks 92. The lifting main punch 91 is fixedly connected to the telescopic end of the cylinder 2. The multiple oblique sliding bending blocks 92 are arranged around the outer ring of the lifting main punch 91, and the multiple oblique sliding bending blocks 92 are all slidably installed on the bottom surface of the upper mold base 1. The lifting main punch 91 and the multiple oblique sliding bending blocks 92 of the outer ring are slidably connected by an oblique snap-fit ​​guide groove 93.

[0030] Eight inclined sliding bending blocks 92 are provided. When the bearing mesh 100 is stamped and sealed, the lifting main punch 91 moves downward under the drive of the cylinder 2, so that the bottom surface of the lifting main punch 91 is flush with the bottom surface of the eight inclined sliding bending blocks 92 around it. This makes the upper die middle punch 9 in a flush state, which makes it easy for the upper die middle punch 9 to press and fix the bearing mesh 100. After the bearing mesh 100 is stamped and sealed, the bearing mesh 100 will be locked onto the upper die middle punch 9. At this time, during the upward movement of the upper die base 1, the lifting main punch 91 is driven to move upward synchronously by the cylinder 2. At the same time, the lifting main punch 91 can drive the eight inclined sliding bending blocks 92 around it to slide and shrink inward through the inclined locking guide groove 93, so that the cross-sectional area of ​​the upper die middle punch 9 is reduced and the bearing mesh 100 falls off the upper die middle punch 9, thereby realizing the automatic demolding and unloading of the bearing mesh 100.
