The invention relates to the technical field of press remoulding, in particular to a protection and automation device of a press for casting preliminary correction. The protection and automation device solves the problems a traditional press is low in work efficiency due to inconvenient workpiece taking-placing and limited working space, and the traditional press has great safety risks without a protective device. The protection and automation device comprises a protective part and a slide platform part; the protective part comprises a left side frame, a right side frame, and a door frame; theleft side frame and the right side frame are separately fixed on two sides of a press platform, the door frame, the left side frame, and the right side frame are all connected with track sliding block pairs, door cylinders, and button boxes; and by operating buttons in a button box at the same time, the jacking of the door frame can be completed, part of the sliding platform is arranged on the press platform and the sliding platform comprises a sliding platform which can horizontally move along the press platform. According to the protection and automation device of the press for casting preliminary correction, the independence of a whole device is good, the device can be installed on the traditional press, the simple and convenient installation process is achieved, during working, the working is required to be operated by both hands need to operate, and the security is higher.
