The utility model provides a 3C product injection mold with secondary guide structure has mainly set up first guide bar and second guide bar, and first guide bar is connected between upper die base and die holder throughout, plays whole direction, and the second guide bar plays the secondary guide effect of supplementary nature, and it only plays the guide effect when the upper die base is about to piece together in the die holder or is about to leave the die holder, consequently can improve the position precision of compound die in-process.

Therefore, compared with the prior art, the structure has the following advantages:

1. the position precision in the injection molding and die assembling process is improved.

2. The injection molding effect and the size precision of the injection molding piece are improved.

3. The second guide rod with higher precision adopts instant guide, namely, the guide function is played at the key moment of mold closing, the service time of the second guide rod is shortened as much as possible, and the service life is prolonged.
