一种生产盒体的注塑模具的侧壁进浇结构
By adopting an X-shaped flow channel design in the injection mold, the molten adhesive is sprayed out from the side wall of the molded block, which solves the adhesion problem caused by the molten adhesive being poured at the top in traditional molds, and achieves high-quality molding of box-type plastic iron products.

AI Technical Summary
When using traditional injection molds to produce box-shaped products with integrated plastic and metal bodies, the molten plastic is poured directly onto the top of the molded block, resulting in gate residue. This affects the integrity of the product's appearance and may cause scratches on the outer surface, thus impacting the quality of the finished product.
The X-shaped flow channel design uses four glue nozzles located between the front and rear molding blocks. The molten glue is sprayed from the side wall of the molding block, avoiding direct pouring onto the top of the molding block and ensuring the integrity of the product's appearance.
This effectively prevents the molten adhesive from sticking to the solidified product, ensuring a smooth and undamaged product appearance and improving the quality of the finished product.
