Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molded parts technology, and in particular to an impact testing device for injection molded parts. Background Technology
[0002] Injection-molded parts refer to parts or components manufactured through injection molding. After the injection-molded parts are produced, it is necessary to test the impact force of the parts. This is done by subjecting a heavy object to free fall to simulate the impact force on the parts. Since the shape and thickness of different parts vary, different impact tests are required for different locations on the parts. However, existing testing equipment is not convenient for adjusting the impact position, making it difficult to perform impact tests on different locations on the parts. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of adjusting the impact position, which makes it difficult to conduct impact tests on different positions of parts. Therefore, this invention proposes an impact testing device for injection molded parts.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design an impact testing device for injection molded parts, including a base plate, on which a first telescopic rod is fixedly connected, and a connecting frame is fixedly connected to the first telescopic rod. Second telescopic rods are fixedly connected to both ends of the connecting frame, and abutment blocks are fixedly connected to each of the two second telescopic rods. A square column is connected to the base plate via a moving mechanism, and scale lines are provided on the square column. A connecting sleeve is connected to the square column via a fixing mechanism, and a weight is placed inside the connecting sleeve. The weight is supported by a support mechanism.
[0006] Preferably, the moving mechanism includes a threaded rod, which is rotatably connected to the base plate via a bearing. The threaded rod is threaded through the square column, and a sliding mechanism is provided at the lower end of the square column.
[0007] Preferably, the sliding mechanism includes a slide rail, which is fixedly connected to the base plate, and a guide groove is provided on the square column, which is slidably disposed on the slide rail.
[0008] Preferably, the fixing mechanism includes a fixing sleeve, which is fitted onto the square column, and a fastening bolt is threaded through the fixing sleeve and abuts against the square column.
[0009] Preferably, the support mechanism includes a third telescopic rod, which is fixedly connected to the fixed sleeve, and a support block is fixedly connected to the third telescopic rod.
[0010] The present invention proposes an impact testing device for injection molded parts, which has the following advantages: by using a second telescopic rod for extension and retraction, the abutment block clamps and fixes the parts, while the first telescopic rod extends and retracts, causing the parts to move longitudinally in the horizontal plane. The moving mechanism adjusts the position of the weight laterally so that the weight collides and impacts different positions of the parts when it falls, thereby conducting impact tests on different positions of the parts.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Example 1: Refer to Figure 1-3 An impact testing device for injection molded parts includes a base plate 1, a first telescopic rod 3 fixedly connected to the base plate 1, a connecting frame 2 fixedly connected to the first telescopic rod 3, and second telescopic rods 4 fixedly connected to both ends of the connecting frame 2. Abutment blocks 5 are fixedly connected to each of the two second telescopic rods 4. A square column 14 is connected to the base plate 1 via a moving mechanism. The square column 14 has scale lines 10 and a connecting sleeve 6 is connected to the square column 14 via a fixing mechanism. A weight 7 is placed inside the connecting sleeve 6 and supported by a support mechanism. By extending and retracting the second telescopic rods 4, the abutment blocks 5 clamp and fix the parts. Simultaneously, by extending and retracting the first telescopic rod 3, the parts move longitudinally in the horizontal plane. The moving mechanism adjusts the position of the weight 7 laterally so that the weight impacts different positions of the parts when it falls, allowing for impact testing at different locations.
[0017] The moving mechanism includes a threaded rod 12, which is rotatably connected to the base plate 1 via a bearing. The threaded rod 12 is threaded through the square column 14, and a sliding mechanism is provided at the lower end of the square column 14.
[0018] The sliding mechanism includes a slide rail 13, which is fixedly connected to the base plate 1. A guide groove 16 is provided on the square column 14, and the guide groove 16 is slidably disposed on the slide rail 13. By rotating the threaded rod 2, the square column 14 will be driven to slide on the slide rail 13, thereby driving the connecting sleeve 6 to move, so that the weight 7 can be adjusted laterally.
[0019] The support mechanism includes a third telescopic rod 8, which is fixedly connected to the fixed sleeve 11. A support block 9 is fixedly connected to the third telescopic rod 8. When the third telescopic rod 8 is retracted, the support block 9 is released from supporting the weight 7, and the weight 7 will fall freely, impacting the components.
[0020] Example 2: Refer to Figure 1-3 As another preferred embodiment of this utility model, based on embodiment 1, the fixing mechanism includes a fixing sleeve 11, which is sleeved on the square column 14. A fastening bolt 15 is threaded through the fixing sleeve 11 and abuts against the square column 14. By moving the position of the fixing sleeve 11 on the square column 14, the height of the weight 7 can be adjusted, and the magnitude of the impact force can be changed when impacted at different positions. The fixing sleeve 11 is fixed by using the fastening bolt 15.
[0021] During the impact test, the height of the fixed sleeve 11 is adjusted according to the magnitude of the impact force borne by the part. The weight 7 is placed into the connecting sleeve 6. Rotating the threaded rod 2 will cause the square column 14 to slide on the slide rail 13, thereby moving the connecting sleeve 6 and allowing the weight 7 to move laterally. The first telescopic rod 3 extends and retracts, causing the parts to move longitudinally in the horizontal plane, moving the weight 7 directly above the part to be tested. The third telescopic rod 8 retracts, causing the support block 9 to detach from the support of the weight 7. The weight 7 will then undergo free fall, simulating the impact on the parts. If the parts are damaged, the test is unqualified.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
