With gear and pinion rack reinforcing synchronizing organization equipped, the movement of mould is precise and rapid, the height of products are even. The down mould can operate steadily and without being shocked while starting and stopping. The mould support and guiding columns is with long guiding sleeves to make sure precision of guiding and long life time of device. The movement from vibrating position to demoulding position of whole body is driven and adjusted by proportion valve and double buffered hydraulic cylinder. The movement is rapid and steady.
