Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a highly adaptable dual-purpose injection mold. Background Technology

[0002] Headlight trim is an important component of the automotive headlight structure. Depending on the user's needs, vehicles now have different configurations. For example, in the same model, higher-spec vehicles need to install reading lights, voice-activated cameras, and other equipment on the roof rack, so a window needs to be reserved for installation, while lower-spec vehicles do not need to reserve a window for the roof rack.

[0003] Therefore, even with the same roof rack shape, different injection molds still need to be developed to differentiate between roof racks with and without windows. However, this undoubtedly increases production costs significantly and can easily lead to confusion during use, thus affecting work efficiency and product yield. Utility Model Content

Detailed Implementation

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below. 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 skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Please see Figure 1 The embodiments of this utility model include: A highly adaptable dual-purpose injection mold, the structure of which includes: a rear mold core 1, a molding cavity 2, a mounting groove 3, a locking hole, a first window molding component, and a second window molding component.

[0016] The rear mold core is provided with a molding cavity for injection molding of the main body of the roof panel. The molding cavity is provided with an installation groove, and the bottom of the installation groove is provided with a locking hole. The installation groove is movably connected to the first window molding component or the second window molding component.

[0017] In a further preferred embodiment, the rear mold core is provided with multiple positioning blocks 4, which surround the sides or all around the molding cavity.

[0018] The first window forming assembly includes a first insert 5, a window forming punch 6, a first connecting through hole 7, and a first locking screw 8. The top of the first insert is provided with a window forming punch, and the top surface of the window forming punch protrudes from the top surface of the imitation forming cavity so as to form a window on the roof panel body. The first connecting through hole passes through the window forming punch and the first insert vertically. The bottom end of the first locking screw passes through the first connecting through hole from top to bottom and connects with the locking hole to fix the first insert in the mounting groove, so that the imitation forming cavity, the top surface of the first insert, and the window forming punch form a first overall cavity for forming a roof panel with a window.

[0019] The second window molding assembly includes a second insert 9, a second connecting through hole 10, and a slotted screw (standard part) 11. The top surface of the second insert is a flat structure, and the second connecting through hole is provided through the top and bottom of the second insert.
