The invention relates to the field of cutting equipment, in particular to a semi-automatic cutting device for a bakelite plate. The device comprises a working table, a guide mechanism, a pushing mechanism and a cutting mechanism; the guide mechanism comprises a first guide component, a second guide component and a limiting component which are arranged at the two ends of the working table in the wide edge direction respectively, the pushing mechanism comprises a pushing component and a first driving component, the first driving component drives the pushing component to move in the long edge direction of the working table, the cutting mechanism comprises a cutting machine and a second driving component, and the second driving component drives the cutting machine to move in the width direction of the working table. The device has the advantages that by means of the guide mechanism, it is guaranteed that when the bakelite plate is cut, the bakelite plate cannot shift, cutting errors cannotbe caused to the bakelite plate, cost waste in production is reduced, the bakelite plate can be cut continuously, and the cutting efficiency is improved.
