[0022] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-5 The present invention provides a technical solution: a testing device for injection molding plastic production, comprising a testing device body 1, a mounting frame 2 movably connected to one side of the testing device body 1, a connecting block 3 fixedly connected to the front of the mounting frame 2, a sleeve 4 movably connected to the inner wall of the connecting block 3, a front baffle 5 fixedly connected to one end of the sleeve 4, a sleeve rod 6 movably connected to the inner wall of the sleeve 4, a rear baffle 7 fixedly connected to one end of the sleeve rod 6, and an adjusting tube 8 fixedly connected to one side of the mounting frame 2.

[0024] An adjusting rod 9 is movably connected to the inner wall of the adjusting tube 8. One end of the adjusting rod 9 is fixedly connected to a mounting plate 10. A mounting groove 11 is opened on one side of the mounting plate 10. An insert post 12 is movably connected to the inner wall of the mounting groove 11. One end of the insert post 12 is fixedly connected to a positioning block 15. During testing, after placing the sheet plastic part in the testing area of ​​the testing device body 1, the two positioning blocks 15 can be adjusted by rotating the threaded engagement between the adjusting rod 9 and the adjusting tube 8 to press against both sides of the sheet plastic part. At the same time, the front baffle 5 and the rear baffle 7 are pulled to stretch and move the sleeve rod 6 within the sleeve 4. This allows for adjustment and positioning of the plastic part's sides and front and back positions during strength testing, preventing inaccurate test data due to displacement caused by the lack of positioning restrictions during strength testing. This ensures that the positioned plastic part can be stably tested.

[0025] In this embodiment, the inner wall of the insertion post 12 is movably connected to the insertion rod 13, and one end of the insertion rod 13 is fixedly connected to the handle 14, which allows the positioning block 15 and the adjusting rod 9 to be disassembled and assembled. By setting the insertion rod 13 at the bottom of the handle 14 so that the whole is U-shaped, the insertion rod 13 can be inserted into the insertion post 12 at the same time, so that the positioning block 15 can be replaced according to the needs of use, and the front baffle 5 and the rear baffle 7 can also be disassembled and assembled with the mounting bracket 2, so that they can be installed and used according to the needs of use, thus meeting different usage requirements.

[0026] Example 2

[0027] Based on Example 1, a preferred embodiment of the testing device for injection molding plastic production provided by this utility model is as follows: Figures 1 to 5 As shown: The insert post 12 is wrapped with a rubber sleeve. The insert post 12 has a through groove with the same diameter as the insert rod 13. The insert post 12 is inserted vertically into the through groove about the upper surface of the mounting bracket 2 and is movably connected to the insert post 12. This makes it easy to install the insert rod 13 on the insert post 12 for positioning, and at the same time improves the tightness between the structures, thereby making it easy to disassemble and replace the positioning block 15.

[0028] In this embodiment, the adjusting tube 8 is provided with an inward thread, and the outer wall of the adjusting rod 9 is provided with an outward thread. The adjusting tube 8 is screwed into the inner thread of the adjusting tube 8. By setting two sets of adjusting tubes 8 and 9 on both sides of the detection device body 1, the limiting distance between the two sets of positioning blocks 15 can be adjusted under the threaded cooperation of the adjusting rod 9 and the adjusting tube 8. This allows for limiting the two sides of the plastic parts of sheet material, making it easy to adjust the size of the positioning according to the detected plastic parts, thus improving applicability.

[0029] Furthermore, both the sleeve 4 and the sleeve rod 6 are wrapped with rubber fastening sleeves. The sleeve rod 6, wrapped with rubber fastening sleeves, is inserted into the sleeve 4 from the open end, and the inner diameter of the sleeve 4 matches the diameter of the sleeve rod 6. By fitting the rubber fastening sleeve on the outside of the sleeve rod 6 into the inside of the sleeve 4, the convenience of adjusting and positioning sheet-like plastics can be improved. At the same time, the tightness between the sleeve 4 and the connecting block 3 and the sleeve 4 and the sleeve rod 6 can also be improved, thus bringing convenience to the adjustment.

[0030] Furthermore, the side of the detection device body 1 is provided with several studs, and threaded rings are installed on the studs. The mounting frame 2 is provided with several mounting slots, and the mounting frame 2 is connected to the studs through the mounting slots, which facilitates the installation of the mounting frame 2 as a whole to one side of the detection device body 1.

[0031] In use, place the sheet-like plastic part requiring strength testing in the testing area of ​​the testing device body 1, positioning the sheet-like plastic part between the front baffle 5 and the rear baffle 7. Then, according to the size of the plastic part, first rotate the adjusting rod 9. The adjusting rod 9, through its threaded engagement with the adjusting tube 8, can drive the positioning block 15 to move closer to the side of the plastic being tested, so that the positioning blocks 15 on both sides can position the side of the plastic part. Then, push and pull the front baffle 5 to move the sleeve 4 on its back within the connecting block 3, allowing the front baffle 5 to be adjusted back and forth to position the front end of the plastic part. At the same time as pushing and pulling the front baffle 5, the rear baffle 7 can also be adjusted. After pulling the rear baffle 7 to adjust the length of the sleeve rod 6 extending inside the sleeve 4, the rear baffle 7, through the movable engagement of the sleeve rod 6 and the sleeve 4, positions the rear end of the plastic part. At the same time, fastening sleeves are provided outside the sleeve 4 and the sleeve rod 6, which can improve the tightness between the structures, improve the convenience of adjustment operations, and also improve the fit of the structures, thereby increasing the positioning range and reducing the activity space during testing.
