[0008] Furthermore, the ejection mechanism includes a second bidirectional threaded rod, both ends of the second bidirectional threaded rod are rotatably connected to the inner side of the chassis, both ends of the second bidirectional threaded rod are equipped with sliders, the top end of the slider is hinged with a connecting rod, the inner top end of the chassis is provided with a lifting plate, one end of the connecting rod is hinged to the bottom end of the lifting plate, the top end of the lifting plate is installed with an ejection rod, the top end of the ejection rod passes through the top end of the chassis, a second motor is installed on the fourth side of the chassis, and the output end of the second motor is connected to one end of the second bidirectional threaded rod.

[0009] The beneficial effect of adopting the above further solution is that, through the cooperation of the second bidirectional threaded rod, the slider, the connecting rod, and the lifting plate, the second bidirectional threaded rod can be rotated to raise and lower the ejector rod, facilitating the ejector rod to demold the clamped mold. By connecting the output end of the second motor to one end of the second bidirectional threaded rod, the second bidirectional threaded rod can be electrically rotated, thereby achieving automatic demolding operation and improving demolding efficiency and precision.
