[0004] The aforementioned device ejects the workpiece from the mold by moving an upward-moving pusher plate. However, after the workpiece is ejected, manual removal by a worker is still required, and in some cases, the workpiece may become stuck inside the mold, making it difficult to remove smoothly. This not only increases the workload of the workers but may also lead to a decrease in production efficiency. Therefore, an improved jig for the workpiece removal method is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an improved fixture for the part-removal method to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an improved fixture for part removal, comprising a first connecting plate and a second connecting plate. A POM pin is fixedly mounted on the first connecting plate, and a brass pin is fixedly mounted at the end of the POM pin. A vacuum nozzle is fixedly mounted on the second connecting plate, and an air pipe is connected to the vacuum nozzle. A connector is provided at the end of the air pipe. A striking mechanism is connected to the POM pin. The striking mechanism includes a striking pin fixedly mounted on the POM pin and a mechanism housing fixedly mounted in the first connecting plate. An impact block is movably mounted inside the mechanism housing. A pressure cap is movably mounted at one end of the mechanism housing. A storage spring is provided inside the pressure cap, and a driving mechanism is provided on one side of the pressure cap.

[0007] Preferably, the housing of the mechanism is provided with a first sliding groove, the pressure cap is provided with a second sliding groove, the impact block is fixedly installed with a sliding support foot, the sliding support foot is slidably installed in the first sliding groove, the end of the second sliding groove is fixedly installed with a wedge block, and the housing of the mechanism is provided with a return spring.

[0008] Preferably, the front end of the mechanism housing has a through hole, through which the firing pin extends into the mechanism housing.

[0009] Preferably, one end of the return spring is connected to the impact block, and the other end of the return spring is connected to the end of the mechanism housing. One end of the power storage spring is connected to the impact block, and the other end of the power storage spring is connected to the end of the pressure cap. The elastic coefficient of the power storage spring is much greater than that of the return spring.

[0010] Preferably, the drive mechanism includes a housing fixedly mounted on a first connecting plate, a motor fixedly mounted on one side of the housing, a linkage shaft rotatably mounted inside the housing, a cam fixedly mounted on the linkage shaft, a drive shaft fixedly mounted at the end of the motor, a drive shaft fixedly mounted at the output end of the drive shaft, and helical gears fixedly mounted on both the drive shaft and the linkage shaft, with the helical gears meshing together.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, during the pressing of the pressure cap, the energy storage spring undergoes a compression phase until it reaches a fully compressed state. At this time, the wedge block acts on the sliding support foot, causing it to disengage from the front end of the first slide groove. Subsequently, the energy storage spring rapidly releases its stored energy, causing the impact block to apply an impact force to the impact pin. After receiving the impact, the impact pin transfers the energy to the workpiece, thereby loosening the workpiece and facilitating its removal from the mold.

[0015] 2. In this application, when the workpiece is stuck inside the mold, the motor can be activated. After the motor starts, the drive shaft rotates accordingly, which in turn drives the linkage shaft to rotate. The rotation of the linkage shaft drives the cam to rotate, and the cam repeatedly presses down the pressure cap during the rotation process, causing the impact block to continuously strike the impact pin, thereby knocking the workpiece stuck in the mold out of the mold.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an improved fixture for part removal, including a first connecting plate 1 and a second connecting plate 4. A POM ejector pin 2 is fixedly installed on the first connecting plate 1, and a brass ejector pin 3 is fixedly installed at the end of the POM ejector pin 2. A vacuum nozzle 7 is fixedly installed on the second connecting plate 4, and an air pipe 5 is connected to the vacuum nozzle 7. A connector 6 is provided at the end of the air pipe 5. A striking mechanism 8 is connected to the POM ejector pin 2, and a driving mechanism 9 is provided on one side of the pressure cap 805. By using the striking mechanism 8 and the driving mechanism 9 together, the part stuck in the mold can be loosened, making it easier to remove the part stuck in the mold.

[0024] like Figure 2 and Figure 3As shown, the drive mechanism 9 includes a housing 902 fixedly mounted on the first connecting plate 1. A motor 901 is fixedly mounted on one side of the housing 902. A linkage shaft 904 is rotatably mounted inside the housing 902. A cam 905 is fixedly mounted on the linkage shaft 904. A drive shaft 906 is fixedly mounted at the end of the motor 901. A drive shaft 906 is fixedly mounted at the output end of the drive shaft 906. Helical gears 903 are fixedly mounted on both the drive shaft 906 and the linkage shaft 904, and the helical gears 903 mesh with each other. A bearing is provided on the housing 902. The linkage shaft 904 and the drive shaft 906 are rotatably mounted on the housing 902 through the bearing.

[0025] Specifically, when the workpiece is stuck inside the mold, motor 901 can be activated. Once motor 901 is activated, it begins to perform its function, namely, driving drive shaft 906 to rotate. The rotation of drive shaft 906 is then transmitted to linkage shaft 904. After receiving the rotational power from drive shaft 906, linkage shaft 904 also begins to rotate. As linkage shaft 904 rotates, it drives cam 905 to rotate as well. During its rotation, cam 905 reciprocates by pressing down on pressure cap 805. This reciprocating pressing down of pressure cap 805 ultimately causes impact block 808 to continuously strike impact pin 801. Through this continuous impact action, the workpiece is eventually knocked out.

[0026] like Figure 2 , Figure 4 and Figure 5 As shown, the striking mechanism 8 includes a striker 801 fixedly mounted on the POM pin 2 and a mechanism housing 802 fixedly mounted in the first connecting plate 1. An impact block 808 is movably mounted in the mechanism housing 802. A pressure cap 805 is movably mounted at one end of the mechanism housing 802. A storage spring 806 is provided in the pressure cap 805. A first sliding groove 803 is provided on the mechanism housing 802. A second sliding groove 804 is provided on the pressure cap 805. A sliding support foot 807 is fixedly mounted on the impact block 808. The sliding support foot 807 is slidably mounted in the first sliding groove 803. A wedge block 810 is fixedly mounted at the end of the second sliding groove 804. A return spring 809 is provided in the mechanism housing 802. A through hole is provided at the front end of the mechanism housing 802. The striker 801 extends into the mechanism housing 802 through the through hole.

[0027] Specifically, when the pressure cap 805 is pressed down, the energy storage spring 806 undergoes a compression process. This compression continues until the energy storage spring 806 reaches its maximum compression state. Once the energy storage spring 806 is fully compressed, the wedge block 810 activates, pushing the sliding foot 807 away from the front end of the first groove 803. Once the sliding foot 807 is disengaged from the front end of the first groove 803, the energy storage spring 806 rapidly releases its stored energy. As the energy storage spring 806 is released, it drives the impact block 808 to move forward, and the impact block 808 then strikes the ejector pin 801. When the ejector pin 801 is struck by the impact block 808, it transfers the energy generated by the impact to the workpiece stuck in the mold. This energy transfer helps to loosen the workpiece, making it easier to remove the workpiece stuck in the mold. After the impact action is completed, the return spring 809 can drive the impact block 808 to reset.

[0028] Working Principle: During use, both the first connecting plate 1 and the second connecting plate 4 are mounted on the robotic arm. After the mold is opened, the POM ejector pin 2 on the first connecting plate 1 can be sent into the module, and the vacuum nozzle 7 on the second connecting plate 4 can be moved to the side of the workpiece. Then, the POM ejector pin 2 can be controlled to move forward, thereby using the brass ejector pin 3 to push the workpiece away from the mold. After the workpiece is pushed away from the mold, the vacuum nozzle 7 can quickly pick up the workpiece, and the robotic arm can quickly complete the part removal action. When the workpiece is stuck inside the mold, the motor 901 can be started. After starting the motor 901, it will drive the drive shaft 906 to rotate. After the drive shaft 906 rotates, it will drive the linkage shaft 904 to rotate. After the linkage shaft 904 rotates, it will drive the cam 905 to rotate. During the rotation of the cam 905, it will drive the reciprocating pressing cap 805, causing the impact block 808 to continuously hit the impact pin 801, knocking the workpiece stuck in the mold out. When the pressure cap 805 is pressed down, the energy storage spring 806 will be compressed. After the energy storage spring 806 is fully compressed, the wedge block 810 will push the sliding support foot 807 to disengage from the front end of the first slide groove 803. After the sliding support foot 807 disengages from the front end of the first slide groove 803, the energy storage spring 806 will be released. After the energy storage spring 806 is released, the impact block 808 will impact the impact pin 801. After the impact, the impact pin 801 will transfer energy to the workpiece, loosening the workpiece and making it easier to remove the inner workpiece stuck in the mold.
