[0016] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center," "up," "down," "left," "right," "vertical," "horizontal," "inside," "outside," and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be construed as limiting the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-4 As shown, an injection molded part detection device with metal inserts includes a base 1, a support plate 2, two mounting brackets 6, two "U"-shaped PCB boards 5 (the "U"-shaped PCB boards 5 are existing customized products), two telescopic components and two indicator lights 15.

[0019] Specifically, the upper surface of the base 1 is threadedly connected to the support plate 2 (the support plate 2 is made of hard plastic) through a plurality of first screws 8. The upper surface of the support plate 2 is mirrored with two detection grooves 3 and two first blind holes 9. Each detection groove 3 is provided with a plurality of second blind holes 4. An injection molded part is placed in each detection groove 3. The indented shape of the detection groove 3 matches the injection molded part to be detected. Each metal insert of the injection molded part is placed in the corresponding second blind hole 4. The lower surface of the support plate 2 is threadedly connected to two mounting brackets 6 through a plurality of second screws 10. Two "U"-shaped PCB boards 5 are connected to the two mounting brackets 6. Each "U"-shaped PCB board 5 is provided with a plurality of metal sensors 7. The metal sensors 7 can detect whether a metal insert is installed on the injection molded part. Each metal sensor 7 is located below the corresponding metal insert. The inner bottom surface of the base 1 is provided with two telescopic components for lifting the injection molded part. An indicator light 15 is installed on each first blind hole 9.

[0020] Specifically, each telescopic component includes an electric push rod 11 and a support frame 12. The inner bottom surface of the base 1 is connected to the fixed ends of two electric push rods 11. The telescopic end of each electric push rod 11 is connected to the corresponding support frame 12. A plurality of through holes 14 are opened in each detection slot 3. Each support frame 12 passes through the plurality of through holes 14 and is slidably connected to the corresponding detection slot 3.

[0021] Specifically, each first blind hole 9 is provided with a wire management hole 13, and the wires of each indicator light 15 pass through the wire management hole 13 and are electrically connected to the corresponding "return" type PCB board 5. In this way, when the metal sensor 7 detects that the metal insert is missing, the "return" type PCB board 5 will control the indicator light 15 to emit red light, indicating that the injection molded part has failed the inspection. Conversely, the "return" type PCB board 5 will control the indicator light 15 to emit green light, indicating that the injection molded part has passed the inspection.

[0022] Specifically, each support frame 12 passes through the corresponding "U"-shaped PCB board 5; a power supply is provided in the base 1, and the power supply is electrically connected to each electric push rod 11 and each "U"-shaped PCB board 5, and the power supply provides power to each electrical component.

[0023] Working principle: Place two injection molded products to be tested in the detection groove 3 to ensure that the parts to be tested are completely embedded in the detection groove 3. At this time, under the action of multiple metal sensors 7, it can detect whether metal inserts are installed in each installation position of the injection molded parts. When a missing part occurs, the "return" type PCB board 5 will control the indicator light 15 to emit red light, indicating that the injection molded part has failed the inspection. When qualified, the "return" type PCB board 5 will control the indicator light 15 to emit green light, indicating that the injection molded part has passed the inspection. When the inspection is completed, the electric push rod 11 will drive the support frame 12 to move upward. At this time, the support frame 12 passes through the corresponding multiple through holes 14 to push out the injection molded parts that have been tested, making it convenient to take out the injection molded parts. After the injection molded parts are taken out, the electric push rod 11 drives the support frame 12 to move downward.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
