The invention discloses a pretreatment integrated device for a PC component production die platform. The device comprises a first mounting rack, a second mounting rack, a third mounting rack, a firstlifting mechanism, a second lifting mechanism, a transverse driving mechanism and a traveling mechanism, wherein the first mounting rack is of a U-shaped structure with a downward opening, and the bottom end of the first mounting rack is positioned on two sides of the die platform; the second mounting rack is mounted on the first mounting rack through the first lifting mechanism; the third mounting rack is mounted on the second mounting rack through the second lifting mechanism; a scraper is fixedly mounted on the third mounting rack; a cleaning brush and a roller are fixedly mounted on the second mounting rack; a demolding agent spray head is fixedly installed on the first mounting rack; and a scribing head is mounted on the first mounting rack through the transverse driving mechanism. According to the device, first lifting mechanism is used for driving the scraper and the cleaning brush to move up and down, and the second lifting mechanism drives the scraper to move up and down, so that the whole cleaning process is efficiently switched between the cleaning stage and the standby stage, and the working efficiency is greatly improved.
