[0002] In the production of car seat clips, injection molds are often used. Injection molds are tools for producing plastic products; they inject molten material under high pressure into a mold cavity, where it cools and solidifies to obtain the molded product. Multi-cavity injection molds are injection molded parts with multiple injection cavities; they are a type of injection mold that can produce multiple products at once.

[0003] The China Patent Network published a novel multi-cavity injection mold with announcement number "CN210415300U". This mold, through a material distribution mold base, enables multi-cavity injection molding of the entire device. It allows injection from the injection port, with the material being injected into the first and second injection cavities via a multi-head connecting pipe of the material distribution mold base. This allows for simultaneous injection molding in multiple cavities, effectively improving the overall efficiency of the device and making it easier for users to operate.
