The hydraulic driving part 13 drives the pushing column 37 to move, first pushes the hydraulic oil in the hydraulic driving groove 36, the hydraulic oil enters the annular lifting groove 34, lifts up the annular supporting seat 12, and supports the injection molded product. According to the required supporting area, the corresponding hydraulic driving part 13 is controlled to start, so as to realize the selective lifting of different annular supporting seats 12.

[0042] The above-mentioned hydraulic driving part 13 can adopt a hydraulic rod.

[0043] The hydraulic supply mechanism comprises a pushing piston 38 arranged in one of the hydraulic drive grooves 36 corresponding to and communicating with the annular lifting groove 34 with the largest diameter, and a spring member 40 fixed to one side of the pushing piston 38, and a fixed blocking ring 39 fixedly connected to the end of the spring member 40 away from the pushing piston 38 and fixedly connected to the inner wall of the hydraulic drive groove 36. The hydraulic drive member 13 drives the pushing column 37 to move, first pushes the hydraulic oil in the hydraulic drive groove 36, and the hydraulic oil enters the annular lifting seat 12 to lift the annular lifting seat 12, and with the continuous movement of the pushing column 37, the pushing column 37 drives the pushing piston 38 to move, the pushing piston 38 pushes the hydraulic oil in the hydraulic drive groove 36, and then the hydraulic oil enters the hydraulic cylinder 22 through the hydraulic delivery pipe 14, so that the hydraulic cylinder 22 drives the detection rod 23 to move downward, and under the limiting action of the fixed blocking ring 39, the pushing piston 38 can move forward by the same distance each time, so that the pushing force of the pushing column 37 is consistent.

[0044] In the case of lifting different annular lifting seats 12, different areas of the injection molded product can be supported, and in the case of the same downward pressure of the detection rod 23, the strength of the injection molded product under different supporting forces can be detected.

[0045] In the implementation process of the present application, the conveying belt 9 is started to stably place the injection molded product on the annular lifting seat 12 of the feeding seat 11. The product placement position is ensured to be accurate, located at the center position of the annular lifting seat 12, and the detection result is avoided to be affected by deviation.

[0046] According to the predetermined annular lifting seat 12, the corresponding hydraulic drive member 13 is operated. The hydraulic drive member 13 drives the pushing column 37 to move in the hydraulic drive groove 36, pushes the hydraulic oil into the annular lifting groove 34, so as to lift the selected annular lifting seat 12, and the injection molded product is stably supported.

[0047] For example, if the second largest diameter annular lifting seat 12 is needed to support and detect the injection molded product, the corresponding hydraulic drive member 13 is started, and the largest annular lifting seat 12 is lifted by the corresponding hydraulic drive member 13. At this time, the largest annular lifting seat 12 and the second largest annular lifting seat 12 both support the injection molded product.

[0048] Then the detection work is carried out, the rotary drive motor 30 is started, the driving gear 31 is engaged with the annular tooth groove 18 in the inner wall of the upper ring seat 15, the linear guide rail 19 and the moving block 20 are driven to rotate around the center of the upper ring seat 15, and the detection rod 23 is roughly aligned above the injection molded product. Then the displacement drive motor 29 is started, the displacement drive screw 28 is rotated, the driving block 27 drives the moving block 20 to translate along the linear guide rail 19, and the position of the detection rod 23 is accurately adjusted to be located directly above the detection position.

[0049] As the hydraulic drive 13 continues to push the push column 37, the push column 37 drives the push piston 38 to move in the hydraulic drive groove 36. The push piston 38 pushes the hydraulic oil into the hydraulic cylinder 22 through the hydraulic delivery pipe 14, and the hydraulic cylinder 22 drives the detection rod 23 to gradually move downward, thereby exerting pressure on the injection molded product. By observing the reaction of the injection molded product under pressure, relevant data such as the distance of the downward pressure of the detection rod 23 and the pressure value when the product starts to deform or damage are recorded, so as to evaluate the strength of the injection molded product.

[0050] After the detection is completed, the annular supporting seat 12 is lowered to reset by operating the hydraulic drive 13, and the detected injection molded product is taken off from the feeding seat 11. If it is necessary to detect the next product, the feeding operation steps are repeated.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
