Abstract

A foam shoe die for making soles comprises a die core, an upper die having an upper die cavity, and a lower die cooperating with the upper die and having a lower die cavity, and also comprises exhaust vents for exhausting gases in the upper and lower die cavities, the upper die is provided with a material injecting channel and a gas inlet channel, a left projection and a right projection used for forming the shape of the bottom of the whole sole are arranged at the left and right sides of the lower die respectively, the die core is assembled in the center of the upper die cavity, and the left and right sides of the die core correspondingly form left and right grooves cooperating with the left and right projections. The gas blowing show die has the advantages of new structure, no protruding strips of made left and right soles, substantial improvement of the whole performances of the sole, and making cost reduction because of no beveling subsequent technologies of the bottoms of the left or right sole.

Description

technical field [0001] The invention relates to a shoemaking mold, in particular to a foaming shoe mold for making shoe soles. Background technique [0002] Existing blowing shoe molds generally include an upper mold, a lower mold and a mold core. The upper mold and the lower mold are respectively provided with corresponding upper and lower mold cavities, and the mold core is arranged in the space formed by the upper and lower mold cavities. In addition, the left and right side walls of the upper and lower mold cavities form shapes corresponding to the bottom surfaces of the left and right shoe soles. A row of upper piercing columns arranged at intervals is arranged at the side walls of the upper mold cavity. A row of lower piercing pillars matched with a row of upper piercing pillars is arranged on the side wall thereof, the upper mold is provided with an injection channel and an air inlet passage, and the lower mold is provided with an air outlet passage. [0003] The blo...
