[0020] In order to make the purposes, technical schemes and advantages of the embodiment of the utility model more clear, the following will combine the drawings in the embodiment of the utility model, and the technical scheme in the embodiment of the utility model will be clearly and completely described, obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments.

[0021] The separating device for injection molding processing of the automobile hub decorative cover 4 of the utility model can efficiently and accurately cut the flow channel 5 of the injection molded decorative cover 4, and is especially suitable for processing of larger decorative cover 4 or decorative cover 4 with more flow channels 5. Figure 1 、 Figure 2 、Figure 3 and Figure 4 As shown in the following specific embodiments of the present application.

[0022] In the implementation process of the present application, the lower die 1, the upper die 2 and the adjustable cutter 3 device are involved, which are suitable for being installed on the lower pressing end of the pneumatic press.

[0023] The lower die 1 is arranged directly below the lower pressing end of the pneumatic press, and the outer surface of the upper part thereof is matched with the inner surface shape of the decorative cover 4 for supporting and positioning the decorative cover 4. The design of the lower die 1 takes into account the size and shape of the decorative cover 4, which can ensure the stability of the decorative cover 4 after injection molding. The material of the lower die 1 can be selected from high-strength steel or other materials with high temperature resistance and corrosion resistance to ensure its long-term reliability.

[0024] The upper die 2 is located at the lower pressing end of the pneumatic press and can provide sufficient cutting pressure by being connected with the pneumatic press. The lower part of the upper die 2 is provided with an annular mounting groove 6 for mounting the cutter 3. The design of the annular mounting groove 6 is matched with the structural shape of the decorative cover 4, which can realize precise cutting of the flow channel 5 of the decorative cover 4. The middle region of the upper die 2 is provided with a plurality of connecting holes for connecting with the lower pressing end of the pneumatic press, thereby ensuring the stable docking of the upper die 2 with the press.

[0025] The cutter 3 is detachably mounted in the annular mounting groove 6 through the cutter holder 7, the bolt 9 and the mounting seat 8. Specifically, the cutter holder 7 and the cutter 3 are integrally formed and are made of high-hardness material to ensure the sharpness and durability of the cutting edge during cutting. The mounting seat 8 adopts a T-shaped structure, and its cross section is matched with the groove cross section of the annular mounting groove 6, which can be easily clamped in the annular mounting groove 6. The mounting seat 8 can slide in the annular mounting groove 6 along the groove length direction, thereby ensuring the adjustable position of the cutter 3. The bolt 9 is used to fix the cutter holder 7 and the mounting seat 8, so that the position of the cutter 3 can be firmly fixed after adjustment, thereby avoiding the phenomenon of position deviation during cutting. After the bolt 9 is tightened, the cutter 3 can accurately cut the decorative cover 4 at the required position. The fixation of the cutter 3 is mainly realized by the friction force between the cutter holder 7 and the bottom surface of the upper die 2, and the friction force between the mounting seat 8 and the inner wall of the annular mounting groove 6.

[0026] The installation design of the cutter 3 enables the cutter 3 to be adjusted in position according to the specific flow channel 5 position of the decorative cover 4, and the position of the cutter 3 is adjusted by moving the mounting seat 8 to meet the cutting requirements of different flow channels 5 of the decorative cover 4.

[0027] The groove cross section of the annular mounting groove 6 is T-shaped structure, which is consistent with the cross-sectional shape of the mounting seat 8, thereby ensuring that the mounting seat 8 can be accurately clamped in the annular mounting groove 6 and can be appropriately moved in the groove. This design not only ensures that the cutter 3 can accurately cut the flow channel 5 of the decorative cover 4, but also facilitates the adjustment of the cutting position of the cutter 3 under different production requirements.

[0028] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
