Precise plastic mold

The precise plastic mold comprises a base, a lower mold, a driving mechanism and two jacking assemblies, each jacking assembly comprises an outer sleeve and a jacking plate, a telescopic rod is installed in the outer sleeve in a sliding mode, and a sliding block is fixedly installed at the position, located in the outer sleeve, of the outer portion of the telescopic rod; through cooperative work of the driving mechanism and the jacking assembly, when the air cylinder pulls the movable plate to move, the trapezoidal block can make contact with the guide wheel, the guide wheel can roll to the top end of the trapezoidal block, meanwhile, after the position of the guide wheel rises, the telescopic rod can be driven to move upwards, and the sliding block can be driven to stretch the spring; and the telescopic rods can also drive the jacking plates to move upwards, the plastic products in the forming cavities can be jacked upwards, rapid demolding can be conducted, the two sets of jacking assemblies sequentially ej
