The invention discloses a lower stamping die capable of being rapidly replaced, and relates to the technical field of dies. The lower stamping die capable of being rapidly replaced comprises a supportplate, wherein two support columns are fixedly connected to the top ends of the bottom surface of the support plate; two shock absorption springs sleeve the surfaces of the top ends of the two support columns; two stabilization pipes sleeve the bottoms of the two shock absorption springs and the surfaces of the bottom ends of the support columns; two first rubber shock absorption gaskets are fixedly connected to the bottom surfaces of the inner cavities of the two stabilization pipes; and a support seat is fixedly connected to the centre of the top surface of the support plate. According to the lower stamping die capable of being rapidly replaced, a support frame connected together with the die is arranged, and enables the whole die body to have a shock absorption effect, and in this way,the service life of the die can be prolonged; and meanwhile, a first cylinder and a second cylinder are controlled to be started through a control switch, and in this way, fixation and detachment forthe die body can be completed simultaneously, and the practicability of the die is improved.
