[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides Figure 1-3 The illustrated embodiment of a split small insert fixing structure on a progressive die for installing a hood lock buckle comprises:

[0019] A mounting block 1 is provided with a slide groove 2 on its surface, a small insert 3 is provided on one side of the mounting block 1, the small insert 3 is slidably connected to the slide groove 2 through a sliding member 4, and a slider 5 of the sliding member 4 is slidably inserted into the slide groove 2 to connect the small insert 3 to the mounting block 1.

[0020] The sliding member 4 includes a limit block 6 . The sliding block 5 is fixedly connected to the surface of the small insert 3 and protrusions 7 are provided on both sides of the sliding block 5 . The protrusions 7 are engaged with the grooves 8 through the coupling.

[0021] The limit block 6 is fixedly connected to one end of the slider 5, and grooves 8 are provided on both sides of the slide groove 2. The protrusions 7 are matched and engaged with the grooves 8. A limit groove 9 is provided on the surface of the mounting block 1 and located at one end of the slide groove 2. After the slider 5 is slidably inserted into the slide groove 2, the limit block 6 is engaged in the limit groove 9 and slides, and the protrusions 7 on both sides of the slider 5 are engaged with the grooves 8 on both sides of the slide groove 2. When the slider 5 continues to slide, the limit block 6 on the surface of the slider 5 is engaged with the limit groove 9 in the slide groove 2, thereby limiting the small insert 3 so that the small insert 3 can only slide out from the end with the limit groove 9.

[0022] The surface of the mounting block 1 is provided with a plurality of mounting holes 10 , and the surface of the mounting block 1 is also provided with an arc groove 11 , and the mounting block 1 is fixed by screws penetrating the mounting holes 10 .

[0023] The small insert fixing structure is split on the progressive die for installing the engine hood lock, and the slider 5 at one end of the small insert 3 is slidably inserted into the slide groove 2 on the surface of the mounting block 1. When sliding, the protrusions 7 on both sides of the slider 5 are engaged with the grooves 8 on both sides of the slide groove 2, and the limit blocks 6 on the surface of the slider 5 are engaged with the limit grooves 9 in the slide groove 2 under the continuous sliding of the slider 5, so as to limit the small insert 3, so that the small insert 3 can only slide out from the end with the limit groove 9. Under the action of the limit block 6 being engaged in the limit groove 9, the small insert 3 cannot slide out from the end away from the limit groove 9, and the end of the small insert 3 with the limit block 6 is in contact with the workpiece, and the mounting block One end with the limiting groove 9 contacts the inner wall of the mold and the mounting block 1 is fixed into the mold by screws penetrating the mounting hole 10. After the mounting block 1 is fixed, since the end of the small insert 3 with the limiting block 6 faces the inner wall of the mold, the small insert 3 cannot slide out under the action of the inner wall of the mold, so that the small insert 3 clamps and fixes the workpiece between the inner walls of the mold, thereby fixing the workpiece. When the workpiece needs to be disassembled, the mounting block 1 is disassembled by screwing the screws in the mounting hole 10, and the small insert 3 is slid out from the end with the limiting block 6, so that the workpiece can be removed, avoiding the problem of screwing the small insert 3 to fix and disassemble.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
