    • Real time distance and pressure data of a plunger (35) relative to a mold compound is provided by a compensation assembly (29) in a mold press (10). The compensation assembly has a sliding block assembly (30) which moves substantially in the same direction as the plungers (35). The sliding block assembly (30) has pressure control cylinders (33) which limit the pressure plungers (35) can apply. If the pressure on the plungers (35) should exceed this limit, the plungers (35) retract towards the sliding block assembly (30). A sensor (37) is coupled between the sliding block assembly (30) and the plungers (35) to measure the distance the plungers have moved towards the sliding block assembly (30). In one application, the sensor (37) is formed from a linear voltage displacement transducer (LVDT) so the mold press (10) can have real time pressure and distance data.
    • 柱塞(35)相对于模具化合物的实时距离和压力数据由模压机(10)中的补偿组件(29)提供。 补偿组件具有滑块组件30,其基本沿与柱塞(35)相同的方向移动。 滑块组件(30)具有限制压力塞(35)可以施加的压力控制缸(33)。 如果柱塞(35)上的压力应超过该极限,则柱塞(35)向滑块组件(30)缩回。 传感器(37)联接在滑块组件(30)和柱塞(35)之间,以测量柱塞朝向滑块组件(30)移动的距离。 在一个应用中,传感器(37)由线性电压位移传感器(LVDT)形成,因此模压机(10)可以具有实时压力和距离数据。
