Description

Technical Field

[0001] This utility model relates to the field of injection molding of automotive decorative parts, and in particular to a mechanical ejection mechanism for an injection mold of automotive decorative parts. Background Technology

[0002] Automotive trim parts typically refer to components used to decorate a car. During the production of automotive trim parts, injection molding is usually required, which involves the use of injection molds.

[0003] Existing automotive trim injection molds typically include an upper mold, a lower mold, a base plate, and a drive plate. The lower mold is connected to the base plate, and the drive plate is connected to the upper mold. The drive plate then drives the upper mold to move up and down to perform mold closing or opening operations.

[0004] After the lower mold is used to inject automotive trim parts, workers usually need to manually remove the molded parts. Since the molded parts will adhere to the mold cavity, this method may damage the molded parts when the workers pull them out, affecting the molding rate. Therefore, it is necessary to use a mechanical ejection mechanism in the injection mold for automotive trim parts to eject the molded parts. Utility Model Content

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.

[0039] This utility model provides, for example Figure 1-4 The image shows a mechanical ejection mechanism for an injection mold of automotive decorative parts.

[0040] Example 1: Includes a base plate 1, a drive plate 3, and an ejector assembly 4. The base plate 1 is used to support the lower mold 2. The drive plate 3 is used to connect with drive components such as hydraulic cylinders to drive the upper mold to move up and down. The lower mold 2 is installed on the top of the base plate 1. The top of the lower mold 2 is provided with a mold cavity 5. The mold cavity 5 is set according to the shape of the automotive trim part. The drive plate 3 is located above the base plate 1. The ejector assembly 4 is located on the lower mold 2. The ejector assembly 4 is used to lift the automotive trim part formed inside the mold cavity 5.

[0041] Furthermore, the ejector assembly 4 includes a movable plate 41, a through groove, an ejector plate 42, and a connector. The movable plate 41 facilitates the up-and-down movement of the ejector plate 42 via the connector, allowing the ejector plate 42 to extend and lift the molded automotive trim part for easy removal. The ejector plate 42 fits tightly against the interior of the receiving cavity. The movable plate 41 is located at the top of the base plate 1, and the through groove is opened at the bottom of the lower mold 2. The movable plate 41 and the inner cavity of the through groove are slidably interlocked. The mold cavity 5 has a receiving cavity that matches the ejector plate 42. The connector is located between the movable plate 41 and the ejector plate 42 and is used to connect the ejector plate 42 and the movable plate 41.

[0042] Furthermore, the ejection assembly 4 also includes a drive member, a groove 6, and a slide. The groove 6 facilitates the sliding of the connecting post 44 within it. The drive member is located on the side of the lower mold 2 and is used to perform vertical drive operation on the moving plate 41. The groove 6 is opened at the top of the inner wall of the through groove, and the slide is opened at the top of the inner wall of the groove 6.

[0043] Specifically, the connecting components include an assembly plate 43, a connecting post 44, and a locking bolt 412. The assembly plate 43 facilitates the up-and-down movement of the ejector plate 42, providing support for the ejector plate 42. The connecting post 44 connects to the assembly plate 43, facilitating the installation and removal of the assembly plate 43 and the ejector plate 42. The locking bolt 412 facilitates the installation and removal of the assembly plate 43, allowing the ejector plate 42 to be easily removed from the mold cavity 5. The assembly plate 43 is fixedly connected to the bottom of the ejector plate 42. The assembly plate 43 is slidably inserted into the inner cavity of the slide and the groove 6.

The auxiliary plate 47 facilitates the sliding of the push rod 45 and guides its movement. The tension spring 48 generates tension on the movable plate 41, thereby facilitating the movement of the push rod 45 within the drive frame. When 46 moves upward, the tension spring 48 exerts a pulling force on the moving plate 41, causing the moving plate 41 to drive the ejector plate 42 to move upward. The end of the push rod 45 is fixedly connected to the moving plate 41. The drive frame 46 is located on top of the push rod 45. The top of the drive frame 46 is fixedly connected to the drive plate 3. The top of the auxiliary plate 47 is fixedly connected to the mounting plate 411. The side of the mounting plate 411 is threaded with a positioning bolt. One end of the positioning bolt is threadedly connected to the lower mold 2.
