Servo seat-grinding pressure machine

The utility model provides a servo seat-grinding pressure machine which is applicable to the field of the mould, which comprises a pressure machine base (1), a machine body (2), a middle slide block (3) and a movable working platform (5), wherein the machine body (2) of the pressure machine is provided with an elevation adjusting device (22) for controlling the elevation of the middle slide block (3), the machine body (2) of the pressure machine is also provided with an upender (23) for controlling the middle slide block (3) to overturn, the elvation adjusting device (22) is connected with a driving servo motor (20), and the elevation adjusting device (22) and the upender (23) are connected with a servo control system (7). The utility model realizes the stepless adjustment of the elevation of the slide block, so the travel distance of the slide block can be precisely varied randomly, and the high-precise grinding requirement of the mould is satisfied; and at the same time, the middle slide block can overturn 180 degrees along the center of the pressure machine, and the positioning precision is high, so the grinding quality of the mould and the working efficiency are greatly improved.
