This utility model relates to the field of molds and discloses a mold structure for side trimming, including an upper mold base and a lower mold base. A pressure plate is elastically and vertically mounted on the bottom of the upper mold base, and a support base is fixedly mounted on the lower mold base. A cutting tool is mounted on the lower mold base. A transverse demolding structure is provided on the side wall of the support base near the scrap material, which drives the side plate of the workpiece to elastically deform away from the support base when the cutting tool detaches from the workpiece, thereby detaching the workpiece from the support base. A longitudinal demolding structure is provided on the upper end surface of the support base, which drives the workpiece to move upward relative to the support base when the pressure plate detaches from the support base. In this side trimming mold structure, after the cutting tool detaches from the side plate, the transverse demolding structure automatically drives the side plate to elastically deform away from the support base, ensuring that the side plate detaches from the support base. Subsequently, when the pressure plate detaches from the workpiece, the longitudinal demolding structure automatically drives the workpiece to move upward relative to the support base, thereby completing the demolding. The workpiece automatically completes demolding during the mold opening process, making demolding convenient.
