[0015] Preferably, the auxiliary component comprises a guide rod fixedly connected to one side of the top of the base plate, and a synchronous sleeve plate is movably connected to the surface of the guide rod.

[0016] Beneficial Effects

[0017] The utility model provides a two-cavity stamping die structure based on an instrument frame. Compared with the prior art, it has the following beneficial effects:

[0018] (1) The two-cavity stamping die structure based on the instrument frame utilizes the setting of the stamping assembly and adopts the form of two independent cavity mold combinations as a whole, so as to achieve the requirement of stamping two workpieces in one time. A guide inclined plate is used between the two molds to slide and transfer the workpieces, which is relatively convenient and quick. When any mold is damaged or maintained, it can be disassembled separately, which is not only convenient for maintenance, but also the cost of independent simple molds is extremely low and the economic value is high.
