[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Please see Figures 1-2This utility model discloses a clamping and positioning mechanism for injection molded parts, comprising: a base 1, an adjustment mechanism 2 disposed below the base, two sets of mounting brackets symmetrically disposed on the base 3, a sliding block 4 slidably disposed on the mounting bracket, a clamping arm 5 disposed on the side of the sliding block, and a lever assembly disposed between the two sets of clamping arms. The lever assembly includes a fixed bracket 6 disposed on the side of the base plate, a rotating block 7 rotatably disposed on the fixed bracket, and a lever 8 connected to the rotating block. The rotating block passes through the fixed bracket via a rotating shaft, and a limit stop 9 is fixedly installed at the front end of the rotating shaft. Under normal conditions, the limit stop... The device is positioned between two sets of clamping arms. A clamping pad 10 is provided at the head of each clamping arm. The clamping pad is made of rubber and is bonded to the clamping arm. A mounting post 11 is provided on the side of the sliding block away from the clamping pad. An elastic member 12 is sleeved between the two sets of mounting posts. A positioning plate 13 is provided at the top of the mounting post to prevent the elastic member from sliding off the mounting post. The two sets of clamping pads can automatically clamp the outer side of different injection molded parts under the action of the elastic member without the need for operator adjustment. This makes it easy to adapt to injection molded parts of different sizes and achieves the purpose of ease of use.

[0016] Specifically, the adjustment mechanism includes a mounting sleeve 21, a limiting post 22 movably disposed inside the mounting sleeve and extending to the outside, and a fixed base plate 23 disposed at the bottom of the limiting post. Positioning holes 24 are evenly distributed around the circumference of the mounting sleeve. A threaded rod 25 is provided on one side of the mounting sleeve and extends through the other side. A first threaded sleeve 26 and a second threaded sleeve 27 are threadedly connected to both sides of the threaded rod, respectively. When it is necessary to adjust the angle of the base and the clamping arm, simply turn the second threaded sleeve and the first threaded sleeve counterclockwise to remove them. At this time, the threaded rod can be pulled out, and the fixing between the mounting sleeve and the limiting post can be released. The angle of the base and the clamping arm can be changed by rotating the mounting sleeve. After the adjustment is completed, the threaded rod is inserted into the corresponding positioning hole, and the second threaded sleeve and the first threaded sleeve are tightened and installed on the outside of the threaded rod, thus achieving the purpose of easily adjusting the angle according to actual needs.

[0017] Specifically, the mounting bracket has a guide ramp, and a horizontal guide groove (not shown in the figure) is provided on the guide ramp. In this embodiment, the sliding block is slidably disposed in the horizontal guide groove to realize the sliding connection between the two. In addition, in other embodiments, the mounting bracket and the sliding block can also be slidably connected by sliding mating components such as linear guide rails.

[0018] The working principle of this utility model is as follows: When clamping the injection molded part, rotate one end of the lever. At this time, the lever can drive the rotating block to rotate up to 90°. The rotating block drives the limiting block to rotate together, which can release the support and limitation of the limiting block on the clamping arm. The telescopic elastic element pulls the sliding blocks connected on both sides to move towards each other. The clamping arm welded to the outside of the sliding block can move accordingly. The two sets of clamping pads at the front end of the clamping arm can automatically clamp the outside of different injection molded parts without the need for operator adjustment. It is easy to adapt to injection molded parts of different sizes and achieves the purpose of simple operation.

[0019] In summary, the injection molding part clamping and positioning mechanism disclosed in this utility model has the following beneficial effects:

[0020] 1. Simply press down on one end of the rotating lever to rotate the limit block, and the two sets of clamping arms can automatically clamp the outer side of injection molded parts of different sizes without the need for operator adjustment. The operation is simple and convenient, improving production efficiency.

[0021] 2. The adjustment mechanism allows for easy adjustment of the angle of the base and the clamping arm when the angle of the mounting base and clamping mechanism body needs to be adjusted, thus achieving the goal of easily adjusting the angle according to actual production needs.

[0022] The above are merely embodiments of this utility model and do 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, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
