TR shoe mold with automatic demolding function

Abstract

The invention discloses a TR shoe mold with an automatic demolding function. The TR shoe mold with the automatic demolding function comprises an upper cover and a base mold. The side, close to the base mold, of the upper cover is provided with an installation groove. An inner core is arranged in the installation groove. The base mold is provided with a mold cavity matched with the inner core. Theinner core comprises an upper inner core and a lower inner core which are attached to each other. The sides, close to the upper cover, of the upper inner core and the lower inner core are both connected with ejector devices. Each ejector device comprises an ejector block, an ejector rod and a first spring. The side, far away from the base mold, of the upper cover is provided with first grooves located at the positions corresponding to the ejector devices. The ejector blocks are provided with second grooves. The ejector rods are squeezed to be pushed so as to drive the upper inner core or the lower inner core to be disengaged from the installation groove. Since the upper inner core and the lower inner core are staggered, the shoe mold on the inner core can be disengaged from the upper innercore or the lower inner core; lifting rods in the upper inner core and the lower inner core can extend out during disengagement of the upper inner core or the lower inner core, the shoe mold is thoroughly disengaged from the upper inner core and the lower inner core, and then automatic and thorough demolding can be achieved.

Description

technical field [0001] The invention relates to the technical field of shoemaking equipment, in particular to a TR shoe mold that can be automatically demolded. Background technique [0002] The shoe mold mold is used to produce shoe soles. When the mold is opened after high-temperature molding, the formed shoe mold cannot be quickly removed from the mold because it is attached to the mold. The temperature is high, even if the operator wears gloves to take the shoe mold out of the mold, he will still be burned. Chinese Patent No. CN201610294784.2 discloses a shoe mold for easy mold opening, including an upper template and a lower template. The formwork and the lower formwork are movably connected through the turning mechanism, and the relative positions of the upper formwork and the lower formwork are provided with mold grooves, and the two corners of the end of the lower formwork away from the turning mechanism are inlaid with ejection mechanisms, and the ejection mechanism...

AI Technical Summary

Problems solved by technology

[0003] In the above-mentioned patent, the upper template and the lower template are only pushed apart by the ejector mechanism, but the formed shoe mold is still attached to the inner core of the upper template, and the shoe mold still needs to be taken out by hand, which cannot be fundamentally fixed.
