Description

Technical Field

[0001] This utility model relates to the field of mold insert structure technology, and more specifically, to a full-circumference burr-pressing insert structure. Background Technology

[0002] Thin electronic shielding cover processing refers to the process of processing metal materials into thin electronic shielding covers with specific shapes and sizes. Among them, the full-circumference burr-filled substructure realizes the stamping and forming, increases the contact area between the shielding cover and the circuit board, and reduces electromagnetic wave leakage and radiation. Therefore, the full-circumference burr-filled substructure is particularly important.

[0003] In existing published literature, Chinese Patent Publication No. CN206870218U discloses an insert structure. This patent utilizes the design of a double-section insert and the gap fit between the first and second mating surfaces. When the head component is subjected to external impact or pressure, the head component can move and rotate slightly relative to the bottom component to achieve the purpose of automatic adjustment and buffering force discharge. However, this insert structure still has the following defects.

[0004] When processing and forming thin electronic shielding covers, multiple inserts are required for stamping and forming during the full circumference burring process. This results in the need to install each insert one by one and then tighten them with bolts, leading to low efficiency in the insert assembly process. Therefore, a full circumference burring insert structure is needed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a full-circumference burr-pressing insert structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a full-circumference burr-pressing insert structure, including a positioning plate and a sleeve recess, wherein multiple pressing ends are slidably inserted into the top of the positioning plate and near its edge line, and a synchronous locking component is provided on one side of each pressing end;

[0007] The synchronous locking assembly includes a positioning block disposed on one side of the pressing end, and an insertion groove matching the positioning block is provided inside the pressing end; a hinge frame is embedded in the top of the sleeve recess, and a hinge block is installed on the outer wall of the hinge frame near its top position; a linkage ring is welded in the gap formed by multiple hinge blocks; a lower pressure rod and an electric cylinder are arranged sequentially from bottom to top above the linkage ring; multiple pressing ends are arranged in a circular and equidistant arrangement, and the cross-sectional area of ​​the top of the pressing end is larger than the cross-sectional area of ​​its bottom end; the sleeve recess and the hinge block are rotatably connected to the hinge frame; the sleeve recess, the hinge frame, and the hinge block are all made of stainless steel; the lower pressure rod is fixedly connected to the linkage ring and the output end of the electric cylinder respectively.

[0008] Preferably, the inner wall of the pressing end is provided with a guide rod for guiding the horizontal movement of the sleeve recess, and the inner wall of the sleeve recess is slidably connected to the outer wall of the guide rod. The bottom end of the pressing end is integrally formed with an insert by die casting. The cross-sectional area of ​​the bottom end of the insert is smaller than the cross-sectional area of ​​its top end. Reinforcing columns for fixing the positioning plate are installed on both sides of the electric cylinder. The top end of the reinforcing column is welded with a mounting plate for reinforcing the electric cylinder. The reinforcing column is welded to the mounting plate and the positioning plate respectively.

[0009] According to the above technical solution, the starting electric cylinder drives the lowering rod to move downward, the lowering rod drives the linkage ring to move downward, and at the same time the linkage ring causes multiple hinge blocks to move vertically downward. Each hinge block causes each hinge frame to move downward. The bottom end of the hinge frame causes the sleeve recess to slide along the inner wall of the positioning plate and the outer wall of the guide rod. The sleeve recess causes the positioning insert to be inserted into the large insertion groove inside the pressing end, and simultaneously locks multiple pressing ends.

[0010] Preferably, the inner wall of the linkage ring is provided with a guiding mechanism; the guiding mechanism includes a guide pillar disposed on the inner wall of the linkage ring, and a connecting block for supporting the electric cylinder is installed at the top of the guide pillar. The guide pillar is fixedly connected to the positioning plate and the connecting block respectively. A plurality of positioning posts that are vertically slidably connected to the linkage ring are installed on one side of the connecting block. Positioning strips are integrally formed on both sides of each positioning post. The linkage ring is vertically slidably connected to the guide pillar and the positioning strip respectively. The outer walls of the positioning strips and the outer walls of the guide pillars are polished.

[0011] According to the above technical solution, the linkage ring moves downward along the outer wall of the guide pillar, and at the same time, the linkage ring moves downward along the outer wall of multiple positioning pillars. The two positioning strips can also move downward along the inner wall of the linkage ring to avoid the linkage ring from shifting during the downward movement.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a synchronous locking component, the electric cylinder drives the lowering rod to move down, and the linkage ring causes multiple hinge blocks to move vertically downward. Each hinge block causes each hinge frame to move down, and the positioning insert and the insertion slot complete the matching and insertion locking of the pressing edge end. This enables the simultaneous assembly and fixing of inserts on multiple pressing edge ends. The synchronous assembly effectively improves the efficiency of insert assembly.

[0014] 2. The guiding mechanism guides the linkage ring to move downward along the outer wall of the guide pillar. At the same time, the linkage ring moves downward along the outer walls of multiple positioning pillars. The linkage ring can move downward along the outer walls of the guide pillar, positioning strip, and positioning pillars, stably locking multiple pressing ends synchronously and improving the locking firmness.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As attached Figure 1-4 The illustrated full-circumference burr-pressing insert structure is equipped with a synchronous locking component. This synchronous locking component enables the simultaneous assembly and fixing of inserts 11 on multiple burr-pressing ends 2, effectively improving the efficiency of insert assembly. The specific structural configuration of the synchronous locking component is as follows:

[0022] In this embodiment, as shown in the appendix Figure 1-4 As shown, the synchronous locking assembly includes a positioning block 3 disposed on one side of the pressing end 2, and an insertion groove 4 that matches and inserts into the pressing end 2.

[0023] A hinge frame 6 is embedded in the top of the socket 5. A hinge block 7 is installed on the outer wall of the hinge frame 6 near its top. A linkage ring 18 is welded in the gap formed by multiple hinge blocks 7.

[0024] Above the linkage ring 18, from bottom to top, are a pressing rod 8 and an electric cylinder 9;

[0025] The working principle of the full-circumference burr-pressing insert structure in this embodiment is as follows:

[0026] First, align the holes on the mounting plate 13 with the stamping equipment. Then, fix the mounting plate 13 to the stamping equipment by inserting bolts into the holes. After installation, insert multiple pressing end heads 2 into the positioning plate 1. Start the electric cylinder 9 through the button connected to the control cabinet to drive the lowering rod 8 to move down. The lowering rod 8 drives the linkage ring 18 to move down. At the same time, the linkage ring 18 causes multiple hinge blocks 7 to move vertically downward. Each hinge block 7 causes each hinge frame 6 to move down. The bottom end of the hinge frame 6 causes the sleeve recess 5 to slide along the inner wall of the positioning plate 1 and the outer wall of the guide rod 10. The sleeve recess 5 causes the positioning insert 3 to be inserted into the large insertion groove 4 inside the pressing end head 2. The positioning insert 3 and the insertion groove 4 are matched and locked to the pressing end head 2. After locking multiple pressing end heads 2 simultaneously, the positions of multiple inserts 11 will also be determined.

[0027] Finally, when stamping the thin electronic shielding cover, the raw material of the thin electronic shielding cover is placed under the positioning plate 1. The stamping forming equipment drives the mounting plate 13 to move the two reinforcing columns 12 down. The reinforcing columns 12 drive the positioning plate 1 to move the multiple pressing ends 2 down. The pressing ends 2 drive the insert 11 to perform insert extrusion operation on the full circumference of the raw material of the thin electronic shielding cover.

[0028] In this embodiment, as shown in the appendix Figure 1-3 As shown, the inner wall of the pressing end 2 is provided with a guide rod 10 for guiding the horizontal movement of the sleeve recess 5, and the inner wall of the sleeve recess 5 is slidably connected to the outer wall of the guide rod 10, so that the bottom end of the hinge frame 6 can guide the sleeve recess 5 to slide along the inner wall of the positioning plate 1 and the outer wall of the guide rod 10, and can realize the horizontal guiding movement of the sleeve recess 5. The bottom end of the pressing end 2 is integrally formed with an insert 11 by die casting. The cross-sectional area of ​​the bottom end of the insert 11 is smaller than the cross-sectional area of ​​its top end, so that the pressing end 2 can drive the insert 11 to perform insert extrusion operation on the full circumference pressing of the thin electronic shielding cover material, realize full circumference insert stamping, and improve the stamping forming efficiency of the thin electronic shielding cover. The electric cylinder 9 is equipped with reinforcing columns 12 on both sides for fixing the positioning plate 1.

[0029] The top of the reinforcing column 12 is welded with a mounting plate 13 for reinforcing the electric cylinder 9. The reinforcing column 12 is welded to the mounting plate 13 and the positioning plate 1 respectively, so as to align the holes on the mounting plate 13 with the stamping equipment. The stamping equipment drives the mounting plate 13 to move the two reinforcing columns 12 down, and the reinforcing column 12 drives the positioning plate 1 to move multiple pressing ends 2 down, so as to stably realize the downward stamping of multiple inserts 11.

[0030] In this embodiment, as shown in the appendix Figure 2-4 As shown, the inner wall of the linkage ring 18 is provided with a guide mechanism;

[0031] The guiding mechanism includes a guide pillar 14 disposed on the inner wall of the linkage ring 18, and a connecting block 15 for supporting the electric cylinder 9 is installed at the top of the guide pillar 14. The guide pillar 14 is fixedly connected to the positioning plate 1 and the connecting block 15 respectively. A plurality of positioning posts 16 are installed on one side of the connecting block 15 and are vertically slidably connected to the linkage ring 18. Positioning strips 17 are integrally formed on both sides of each positioning post 16. The linkage ring 18 is vertically slidably connected to the guide pillar 14 and the positioning strips 17 respectively. The outer walls of the positioning strips 17 and the outer walls of the guide pillar 14 are polished.

[0032] According to the structure above, when the linkage ring 18 moves downward, the connecting block 15 provides vertical support to the electric cylinder 9. The linkage ring 18 moves downward along the outer wall of the guide pillar 14. At the same time, the linkage ring 18 moves downward along the outer wall of multiple positioning posts 16, and the two positioning strips 17 can also move downward along the inner wall of the linkage ring 18. This ensures that the linkage ring 18 can move downward along the outer wall of the guide pillar 14 and the outer walls of the positioning strips 17 and positioning posts 16, and avoids the linkage ring 18 from shifting during the downward movement.

[0033] All contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used. Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
