Embodiment Construction

[0019] Reference will be made in detail to the preferred embodiments of this invention, examples of which are illustrated in the accompanying drawings.

[0020] Please see Figures 1 to 3 , The sole molding device includes a base 1, which has a cylindrical space, in which a punch 4 is placed. The four support columns 2 are vertically installed on the four corners of the base 1 and have first and second sets of four braking bosses 201 and 202 . An upper plate 3 is fixed on the upper ends of the four supporting columns 2, and the fourth heating pressure plate 11 is installed therein. The fourth heated pressure plate 11 also clamps the third male mold 19".

[0021] The mobile support plate 5 is mounted on the plunger 4 and is connected to the first and second piston rods 6' and 7' of the first and second cylinders 6 and 7, which are fixed to on base 1. A first heated pressure plate 8 and a first female mold 18 are installed on the movable support plate 5 .

[0022] The secon...

Abstract

The shoe sole-moulding machine includes three pairs of foaming male dies and female dies; four heating and pressurizing boards for clamping and heating dies; the first brake for selective braking of the second heating and preeurizing board ascending to the top position; and the second brake for selective braking of the third heating and pressurizing board ascending to the top position. The female dies may be separated from corresponding male dies fast successively, so that the foamed shoe soles produced have excellent shock-absorbing capacity and required shape and thus low production cost and high production efficiency.

Description

technical field [0001] The invention relates to a shoe sole forming device. Background technique [0002] In the prior art CN2221483Y, an improved structure of a shoe midsole mold is disclosed, which forms a higher convex wall through the groove outer edge of the female mold, and the male mold forms an inner concave part closely attached to the above-mentioned convex wall, so that at first Keep the male and female molds in an incompletely sealed state, and after the foaming is complete, make them completely sealed, so as to complete the foam material sole with uniform density. [0003] In addition, usually high-quality foam soles are obtained by placing the foam sheet in a female mold, sealing the female mold with a male mold, heating the mold, and quickly separating the male and female molds so that the heated foam The sheet was exposed to air. On the contrary, if the male mold is slowly separated from the female mold, the foaming of the foam sheet deteriorates, so that a...
