Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a baffle cover injection mold. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0003] Appendix Figure 8 , 9 The invention provides a baffle cover with vertically arranged side panels. A horizontal top plate is fixedly attached to the top of the side panels. Both the side panels and the top plate have folded edges extending vertically inward and parallel outward on their left and right sides. Each folded edge has three forward-protruding locking blocks on the front side of each side portion of the side panel. The bottom of the side panels has legs fixedly attached to the left and right sides, which are on the same plane as their inner surfaces. Locking blocks are provided on the front sides of the two legs. Multiple reinforcing plates are provided on the inner sides of the side panels and the top plate to enhance their structural strength. The rear side of the top plate has rearward-extending lugs near the left and right sides. Each edge of the top plate and the lugs has a downward folded edge with a round hole. A buckle for mounting the device is provided on the rear side of each lug. Both the side panels and the top plate have multiple strip-shaped through holes, and reinforcing ribs perpendicular to the inner surfaces are arranged around the strip-shaped through holes.
