The invention is described by taking a left expansion module and a left contraction module as examples, and the expansion module and the contraction module expand twice to reach the working state position; similarly, the mold is contracted twice to reach the demolding state position. In general, the present invention can be divided into an external expansion and contraction of the module, i.e. a primary expansion, and an internal expansion and contraction of the module, i.e. a secondary expansion and contraction. In detail, the purpose of one-time expansion is to expand the whole module to the working state position of the tool along the horizontal direction; the purpose of one-time shrinkage is to shrink the whole module to the position of a demoulding state of the tool along the horizontal direction.
