Description

Injection mold structure for embedded nut Technical Field The utility model relates to the field of injection mold design, in particular to an injection mold structure for embedded nuts. Background In many injection molded articles, it is often desirable to pre-embed nuts in the article in order to facilitate subsequent assembly or securement. However, the following drawbacks exist in the prior art: However, due to insufficient positioning precision of the die, the embedded nut may have position offset or incorrect angle, which affects subsequent assembly, and due to unreasonable design structure of the die, the injection pressure may shift or drop the nut, which results in embedded failure, and the conventional embedded nut die has complex structure, inconvenient disassembly and cleaning, difficult nut replacement, and increased maintenance cost.
