[0024] The plug product obtained after injection molding is as follows Figure 1 As shown, it includes a wire 11, a core board 12 and a plastic shell 13, and three conductors 121 are arranged on the core board 12. Figure 5 As shown, this embodiment provides a device for removing a power cord plug after injection molding. The device is arranged on an operating table 3 of an injection molding machine and includes a positioning mechanism 4, an ejection mechanism 5, and a plurality of injection molding plates 21.

[0025] Specifically, Figure 3 As shown, nine injection grooves 211 are provided on one side of the top of the injection molding plate 21, and three insertion holes 212 are provided in each injection molding groove 211. Before injection molding, the core plate 12 of the intermediate product needs to be placed in the injection molding groove 211, and the three conductors 121 are inserted into the corresponding three insertion holes 212. After the conductors 121 pass through the insertion holes 212, they protrude from the outside of the injection molding plate 21. The purpose of this design is to facilitate the ejection of the conductors 121 under the action of the ejection mechanism 5.

[0026] like Figure 5 , Figure 6 As shown, the operating table 3 includes a top plate 31, a bottom plate 32 and three side plates 33. The three side plates 33 are arranged between the top plate 31 and the bottom plate 32. A card plate 311 is provided on the top of the top plate 31. The card plate 311 is provided with a card slot. The card slot is used to place the injection molding plate 21. Nine avoidance grooves 314 that penetrate the top plate 31 are provided at the bottom of the card slot. One avoidance groove 314 corresponds to three conductors 121 of a core plate 12 and is used to avoid the conductors 121.

[0027] Specifically, the positioning mechanism 4 is used to fix the injection molding plate 21, and the ejection mechanism 5 is arranged inside the operating table 3, including a lifting assembly 51 and nine blocks 52. The lifting assembly 51 can use a lifting rod driven by an oil cylinder, an air cylinder or a hydraulic cylinder. The nine blocks 52 are arranged on the top of the lifting assembly 51. The blocks 52 match the corresponding avoidance grooves 312. When the lifting assembly 51 lifts the nine blocks 52, it is used to lift the plug. In order to reduce the stroke of the block 52 during the up and down movement, the top of the block 52 is close to the conductor 121. There is another purpose of this design: during the injection molding process, the block 52 plays a role in supporting the conductor 121.

[0028] The method of use is as follows: before injection molding, use the positioning mechanism 4 to fix the injection molding plate 21; after injection molding is completed, first use the lifting assembly 51 to lift the nine blocks 52, so as to lift the plug, and stop after the top surface of the block 52 contacts the injection molding plate 21; then release the positioning mechanism 4 from fixing the injection molding plate 21; then use the lifting assembly 51 to continue to lift the nine blocks 52. At this time, the function of the block 52 is to lift the injection molding plate 21 upward, so that the injection molding plate 21 is separated from the slot, making it easier for the staff to take away the injection molding plate 21; because the plug has been pushed out by the block 52 in the early stage, it is easy for the staff to remove the plug on the injection molding plate 21. The specific operation is: the staff holds the injection molding plate 21 with one hand, and collects all the wires 11 with the other hand, and lifts the wires 11 upward, so that all the plugs on the injection molding plate 21 can be easily removed.

[0029] In the prior art, there are many ways to implement the positioning mechanism 4. The implementation method of this embodiment is as follows: Figure 5 , Figure 7 As shown, the top surface of the clamping plate 311 is flush with the top surface of the injection molding plate 21, the positioning mechanism 4 includes two sprockets 42, a chain 43, a motor 44 and two symmetrically arranged positioning plates 41, the positioning plate 41 is arranged at the outer end of the injection molding plate 21, and is used to press the injection molding plate 21, the positioning plate 41 is a straight line, and a bearing 411 is provided at the bottom thereof, the bearing 411 passes through the top plate 31 and is connected to a sprocket 42, the chain 43 is sleeved on the two sprockets 42, the motor 44 is arranged on the side plate 33 through the support plate, and the output shaft of the motor 44 is connected to one of the sprockets 42.

[0030] The positioning mechanism 4 is used as follows: when it is necessary to release the positioning mechanism 4 from fixing the injection molding plate 21, the motor 44 drives one of the sprockets 42 to rotate 90°, and under the action of the chain 43, the other sprocket 42 is driven to rotate 90°, thereby causing both positioning plates 41 to rotate 90°, thereby detaching from the injection molding plate 21.

[0031] In order to prevent the chain 43 from interfering with the moving tracks of the nine blocks 52, the present embodiment adopts the following measures: Figure 7 , Figure 8 As shown, a rectangular frame 53 is provided on the top of the lifting assembly 51 , and nine blocks 52 are provided on the top of the rectangular frame 53 . The rectangular frame 53 is provided with channels 531 running through both ends thereof, and the chain 43 is located in the channels 531 .

[0032] In order to facilitate the placement of the wire 11, the present embodiment also takes the following measures: Figure 5 , Figure 6As shown, a flat plate 312 is also provided on the top of the top plate 31, and a slot is located on the side of the slot 311 facing the flat plate 312. Nine grooves 313 are provided on the top of the flat plate 312. When the injection molding plate 21 is placed in the slot, the injection molding plate 21 is close to the flat plate 312, and the flat plate 312 serves to limit the injection molding plate 21. The wires 11 are placed in the corresponding grooves 313.

[0033] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
