[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 , 2 As shown, a motorcycle motor cover injection molding device includes a worktable 1, an injection molding platform 2 fixedly mounted on the upper surface of the worktable 1, a plurality of mold slots 9 formed on the front surface of the injection molding platform 2, a plurality of mounting rods 11 fixedly mounted at equal intervals on the upper surface of the worktable 1, injection screws 12 fixedly mounted at equal intervals on the upper surface of the mounting rods 11, the output end of the injection screws 12 being connected to the injection molding platform 2, a support plate 3 fixedly mounted on the upper surface of the worktable 1, a hydraulic cylinder 4 fixedly mounted on the surface of the support plate 3, a guide plate 7 mounted on the output end of the hydraulic cylinder 4, a plurality of mold blocks 8 fixedly mounted at equal intervals on the front surface of the guide plate 7, the mold blocks 8 being disposed inside the mold slots 9, and an ejection assembly 6 being provided on the guide plate 7.

[0021] like Figure 1 As shown, a feed funnel 13 is provided on the upper surface of the injection molding screw barrel 12 to facilitate the conveying of raw materials into the injection molding screw barrel 12.

[0022] like Figure 1 As shown, a cold water pipe 10 is installed inside the injection molding table 2, and water is supplied to the cold water pipe 10 to cool the raw materials inside the injection molding table 2.

[0023] like Figure 1 As shown, a guide rod 5 is slidably mounted through the middle of the support plate 3, and the top end of the guide rod 5 is disposed on the surface of the guide plate 7. This enables the guide plate 7 to have better stability when moving.

[0024] like Figure 2 , 3As shown in Figure 4, the pop-out component 6 includes a slide rod 601 and a storage slot 606. The slide rod 601 is slidably mounted on the mold block 8. The storage slot 606 is formed on the front surface of the mold block 8. A positioning plate 602 is fixedly mounted on the rear end of the slide rod 601. A return spring 603 is fixedly mounted on the front surface of the positioning plate 602. The top end of the return spring 603 is set on the surface of the guide plate 7. A top plate 604 is fixedly mounted on the front end of the slide rod 601. The top plate 604 is set inside the storage slot 606. A positioning groove 607 is formed on the inner surface of the storage slot 606. A positioning block 605 is fixedly mounted on the surface of the top plate 604. Positioning block 605 is located inside positioning groove 607. When the mold needs to be detached, the output end of hydraulic cylinder 4 extends backward, causing positioning plate 602 to contact support plate 3 and generate thrust. This drives slide rod 601 to move forward, causing top plate 604 to move forward and eject the molded mold from mold block 8. After ejection, when hydraulic cylinder 4 moves forward and positioning plate 602 disengages from support plate 3, return spring 603 returns top plate 604 to its original position in receiving groove 606, without affecting subsequent injection molding operations. This device automatically detaches the molded mold, improving injection molding efficiency.

[0025] Working principle of a motorcycle motor cover injection molding device:

[0026] In operation, when injection molding is required, the hydraulic cylinder 4 is first extended or retracted, which drives the guide plate 7 to move forward and simultaneously moves the mold block 8 forward, positioning the mold block 8 inside the mold groove 9. The raw material is then fed from the feed funnel 13 into the injection barrel 12. The injection barrel 12 melts and injects the raw material into the mold groove 9 on the injection table 2. Water is supplied to the cooling water pipe 10 to cool the raw material inside the mold groove 9. After cooling and molding, the hydraulic cylinder 4 is extended or retracted, which drives the guide plate 7 to move backward, positioning the mold block 8 inside the mold groove 9. Block 8 detaches from the mold slot 9, and the formed mold is fitted onto the mold block. When it is necessary to remove the mold, the output end of the hydraulic cylinder 4 continues to extend and retract backward, causing the positioning plate 602 to contact the support plate 3 and generate thrust. This drives the slide rod 601 to move forward, causing the top plate 604 to move forward and push the formed mold off the mold block 8. After ejection, when the hydraulic cylinder 4 moves forward and the positioning plate 602 disengages from the support plate 3, the return spring 603 will return the top plate 604 to the receiving slot 606, without affecting the next injection molding operation. This device can automatically detach the formed mold, improving injection molding efficiency.

[0027] The above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
