In view of this, main purpose of the present utility model is to provide a kind of plastic shoes mould, prolonging the service life of mould, and the quality of the footwear body of can guaranteeing to be shaped.

For achieving the above object, the plastic shoes mould that provides of the utility model includes:

One bed die, top offer can be for the predetermined dimpled grain that forms the sole shape of a footwear body;

Two limit moulds, it is in the relative closing of left and right side of bed die, and the medial end of two limit moulds is recessed into the shape that preboarding becomes footwear body riser in relatively;

One last, vamp on its upper sleeve through, itself and above-mentioned two limit die sleeves merge mould and close in this bed die top, and can form with the sole dimpled grain of this bed die just can be for the predetermined sole of a footwear body and the cloth material space of riser of forming;

Wherein, in this last near bottom periphery, i.e. the position of closing with this two limits die sleeve, around an elastomer is set, this elastomer is fixed on the last with the direct screw lock of several bolt elements.

Also can this elastomer of location be set in this chase in the nearly bottom part of this last around a chase is set.

Understand and approval for the relevant personnel can be had further the purpose of this utility model, feature and effect, now lift after a preferred embodiment and conjunction with figs. be illustrated in.
