Background

Shoes are indispensable to modern people, the structure of shoes includes vamp and sole, often will adopt EVA (polyethylene vinyl acetate) mould pressing technique in the preparation technology of sole, the structure that prior art EVA (polyethylene vinyl acetate) mould pressing adopted is shown in figure 1, including last mould 1a and lower mould 2a, wherein be equipped with the die cavity 3a of sole in lower mould 2a, die cavity 3a is two, be left sole and right sole respectively, be equipped with feed inlet 4a and runner 5a in lower mould 2a, feed inlet 4a communicates with runner 5a, runner 5a still communicates with the die cavity 3a of left and right sole respectively.

In the process of manufacturing the shoe sole, the upper die is usually firstly installed on the upper die base, then the lower die is installed on the lower die base, and then the upper die and the lower die are covered by pressing through the upper die base. And introducing the heated EVA raw material into the feed inlet, and respectively flowing into the die cavities of the left sole and the right sole through the runners. In the prior art, due to the production requirement of the sole, the shape of the sole is designed firstly, a finished product is produced through a mould, and the performance test and the design requirement test are carried out on the finished sole. The mass production can be carried out under the condition of meeting the requirement.

However, if the finished sole does not meet the design and performance requirements, the entire mold is redesigned and produced. Because the upper die and the lower die are both made of cast iron, the lower die contains a left sole die cavity and a right sole die cavity. If the mold needs to be redesigned and manufactured, the original mold is directly scrapped. Therefore, for the traditional mold design, the waste of the mold is likely to occur when the mold is applied to the sole manufacturing process, and the design cost of the whole set of mold is high, so that the cost of producing samples is high for new products, and the technical bottleneck is not favorable for the research and development of the new products.
