Abstract
Description
Technical Field
[0001] This utility model relates to the field of molds, and in particular to a self-locking insert structure. Background Technology
[0002] Inserts are used as inserts for punching holes in molds. Because they use a traditional locking method (screw attachment), screws are required for each disassembly and assembly, resulting in unnecessary workload and wasted time for workers. Utility Model Content
[0003] To address the aforementioned issues, this technical solution provides a self-locking insert structure.
[0004] To achieve the above objectives, the technical solution is as follows:
[0005] A self-locking insert structure includes an insert, wherein the insert has an inclined first limiting groove on its outer periphery;
[0006] It also includes a base for inserting the insert, the base having a second limiting groove that is opposite to and inclined to the first limiting groove, and the second limiting groove having a spring and a limiting ball.
[0007] In some embodiments, the end of the first limiting groove is arc-shaped and matches the outer surface shape of the limiting ball.
[0008] In some embodiments, the base is provided with a through hole located above the second limiting groove.
[0009] In some embodiments, the through hole is movably connected to an insertion rod.
[0010] The beneficial effects of this application are:
[0011] After the insert is inserted into the base, the spring drives the limiting bead to the end of the first limiting groove to limit it because the first limiting groove and the second limiting groove are connected. After the insert is installed, its movement is restricted to prevent the insert from falling off and being pulled out due to the vertical pulling force in the stamping production. Attached Figure Description
[0012] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.
[0013] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model;
[0014] Figure 2 This is a cross-sectional schematic diagram of an embodiment of the present invention. Detailed Implementation
[0015] To make the technical problems solved, technical solutions, and beneficial effects 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.
[0016] Please refer to Figure 1-2 As shown, a self-locking insert structure includes an insert 1, wherein the insert 1 has an inclined first limiting groove 2 on its outer periphery;
[0017] It also includes a base 3 for inserting the insert 1, the base 3 having a second limiting groove 4 that is opposite to and inclined to the first limiting groove 2, and the second limiting groove 4 having a spring 5 and a limiting ball 6.
[0018] After the insert is inserted into the base, the first and second limiting grooves are connected. Therefore, the spring drives the limiting ball to the end of the first limiting groove for limiting. This restricts the insert's movement after installation, preventing it from falling out due to vertical pull-out forces during stamping production. This self-locking structure allows for the installation and replacement of the insert simply by lifting the internal limiting steel ball.
[0019] To use, insert a steel ball into the through hole in the base, then insert the insert. The steel ball can be removed after the insert is removed.
[0020] To address the issue of insert mounting and dismounting, this mounting method has been improved to reduce the workload of workers and facilitate quick and easy insert replacement and repair without disassembling the mold.
[0021] When inserting the insert into the cavity, simply press the insert down slowly.
[0022] At this point, when the fixing groove of the insert is in the same position as the steel ball limiting ball in the fixing seat, the steel ball is pushed into the insert groove by the spring force.
[0023] The insert is now in place and cannot be pulled upwards.
[0024] When the insert needs to be removed, simply use a special steel needle to push the limiting steel ball forward to a certain position, and then disengage it from the insert limiting slot, so that the insert can be removed.
[0025] The insert disassembly process has been optimized, and the inserts are self-locking via limiting steel balls, resulting in miniaturization and simplified mold repair. It is applicable to various structural applications (not limited to molds).
[0026] In this embodiment, the end of the first limiting groove 2 is arc-shaped and matches the outer surface shape of the limiting ball 6. This ensures that there is no excess space when the steel ball abuts against the first limiting groove, preventing the insert from shaking and also preventing jamming.
[0027] In this embodiment, the base 3 is provided with a through hole 7 located above the second limiting groove 4.
[0028] In this embodiment, the through hole 7 is movably connected to the insertion rod 8. When the insert is removed, a steel needle is inserted into the through hole to compress the spring, thus achieving the unlocked state.
[0029] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
