Abstract

A blow shoe mould comprises an upper mould with an upper mould cavity, a lower mould with a lower mould cavity, and a mould core installed between the upper and lower moulds; the blow shoe mould further comprises an air discharging outlet installed on the upper mould for discharging air in the upper and lower mould cavity; the rear side of the mould core is hinged with the lower mould; the rear side of the upper mould is hinged with the rear side of the mould core; the upper mould is provided with a material injection passage and an air inlet passage; the air inlet passage comprises an air inlet installed on the top of the upper mould and a plurality of small holes communicated with the air inlet and densely distributed on the top of the upper mould cavity; the air discharging outlet is installed on the upper mould; the air inlet passage further comprises an edge passage formed by butting the upper and the lower passages; the upper passage is installed on the periphery of the upper mould cavity and communicated with the air inlet; and the lower passage is installed on the periphery of the lower mould cavity and communicated with the lower mould cavity. The shoe mould uses a plurality of small holes to blow with the lower passage in different directions; the air discharging outlet is installed on the upper mould; thus, the gas can be sealed in the mould cavity so that foam materials such as PVC can be fully foamed.

Description

technical field [0001] The invention relates to a shoemaking mold, in particular to an air blowing shoe mold. Background technique [0002] Existing air-blowing shoe molds generally include an upper mold, a lower mold and a mold core located between the upper mold and the lower mold. One side edge of the mold core is hinged with the lower mold. The side edge is hinged, and the upper mold is provided with an injection channel and an air intake channel. The lower mold is composed of holes, and the lower mold is provided with an air outlet channel. [0003] The blowing injection molding process is that foam materials such as PVC enter the mold cavity formed between the upper mold and the lower mold through the injection channel of the upper mold, and the high-pressure gas enters through the air inlet, and then blows out through multiple small holes. The gas in the mold is discharged from the mold cavity through the air outlet channel on the lower mold. This blowing and injec...
