Mould structure for one-mould eight-products

The utility model relates to a rubber injection mould and discloses a mould structure for one-mould eight-products. The mould structure comprises a charging plug, a charging cavity, a middle mould plate and a lower mould plate, wherein the middle mould plate consists of a plurality of module plates; the module plates positioned on two end parts of the middle mould are connected with the lower mould through inclined surfaces; and positioning pins are arranged on the module plates positioned in the middle of the middle mould. The mould structure has the beneficial effects that the mould structure is reliable in positioning and convenient in demoulding; meanwhile, the self-locking function is realized when rubber injection is carried out so as to ensure that the positioning abrasion of the mould is less, the service life of the mould is prolonged and the production efficiency is improved.
