Moulding block used to mould two sizes of shoe, reducing cost and inventory logistics - has two part-inserted shoe moulds for contiguous shoe sizes, which rest against top inward flange of moulding block along line of common conformation and dimension

摘要

This plastic injection moulding equipment for shoes, comprises a moulding block (20) in two halves (not shown). A novel feature is the inward, peripheral flange of the upper edge of the cavity, when the halves are assembled to form the block. First (30) and second (40) shoe moulds of differing consecutive size, define an adjusting peripheral line common to both. Thus when either first or second shoe mould is placed in the cavity, part housed within it, the peripheral flange is positioned along this line. This permits the shoemaker to make two different contiguous sizes within one moulding block.
