The invention relates to a high-precision two-station covering part die, and belongs to the technical field of automobile dies. The die has the advantages that a pair of dies is stamped in two trimming processes at the same time, so that the die manufacturing cost is lowered; and compared with one-time trimming process, the two trimming processes have the advantages that through the adjustment of the trimming direction, the vertical trimming is carried out for different technical addendum surfaces, so that the product edge precision is higher. A trimming knife block of the covering part die is a combined knife block, and is easy to replace as compared with an integrated knife block, so that the service life of the die is prolonged; an upper die holder and a lower die holder are guided by internal guiding plates and a combined guiding structure formed by guide pillars and bushes, external guide plates and back blocks at the same time, so that not only is the precise guiding facilitated, but also the lateral force generated after a female die and a male die are in contact with each other is beneficial to cancellation, the damage of the female die and the male die is avoided, tapered positioners are used to guide the female die and the male die in the second process, so that the final precision after the product edge is trimmed is ensured, and the precision and safety of the movement of the die are ensured through using a plurality of position limiting mechanisms.
