Shoe sole forming device

Abstract

The novel shoe sole forming device provided by this invention includes a base, a first mold, a linkage mechanism, a second mold, a first shoe last, and a second shoe last. The first mold comprises a first mold body and a second mold body, which are respectively located side-by-side on the base. It also includes a first mold chamber defined by the first mold body and an open first mold chamber, and a second mold chamber defined by the second mold body. The linkage mechanism is connected to both the first mold body and the second mold body, and synchronously drives the first mold body and the second mold body. The second mold body moves between a first mold opening position and a first mold closing position; the second mold is spaced apart from the first mold and can move between a second mold opening position spaced apart from the first mold and a second mold closing position attached to the first mold; the first shoe last and the second shoe last can be respectively fitted by a first set of fittings and a second set of fittings, and are attached to the second mold in a parallel and detachable manner; when the second mold is in the second mold opening position, the first shoe last and the first mold... The two shoe lasts move synchronously away from the first mold as the second mold moves; when the second mold is in the second mold-closing position, the first shoe last is inserted into the first mold chamber and the second shoe last is inserted into the second mold chamber simultaneously; wherein, before the second mold changes its position, the positions of the first mold body and the second mold body are changed first, so that the linkage mechanism simultaneously drives the first mold body and the second mold body to move from the first mold-closing position to the first mold-opening position; and then the second mold body is changed. The location of the mold is determined, causing the second mold to move from the second mold opening position to the second mold closing position; then, the linkage mechanism simultaneously drives the first mold body and the second mold body to move from the first mold opening position to the first mold closing position, thereby defining a first sole forming space by the inner wall surface of the first mold chamber and the outer periphery of the first shoe last, and defining a second sole forming space by the inner wall surface of the second mold chamber and the outer periphery of the second shoe last, so as to perform sole forming operations simultaneously.
