Abstract

The invention relates to the shoe industry and allows for improved productivity and improved hygienic properties of the finished footwear. The top of the top is produced on the injection block, which has a wave-like relief in the sock-beam and gelenochny parts of the track, the crests of which are placed parallel to the contour of the insole. Before closing the semi-matrix, an additional drawing of the bulk top is carried out by means of a relief formation of the inner insole by means of a profiled pad track and a punch having a relief opposite to the pad trace. 6 Il.

Description

The invention relates to the shoe industry and can be used for the manufacture of textile and leather shoes injection molding method.

The purpose of the invention is to increase labor productivity and improve the hygienic properties of the finished footwear.

FIG. Figure 1 shows the pattern for molding the top on the injection block; in fig. 2-4 are successive stages of the process; in fig. 5 - shoes are ready, cross section; Fig. 6 is a schematic representation of the location of the ridges of the relief along the track of a block.

A bulk workpiece is made close to the pad volume, taking into account the subsequent elastic-plastic deformation of the workpiece materials, consisting of the top 1 and the insock 2, measuring 5-7 mm in size

track pad 3, put the workpiece on the pad 3 of the injection molding machine (Fig. 2), equipped with a plate 7 with a wavy relief in the sock-tuft and gelenochnyh parts (Fig. 6), the crests 11 of which are placed parallel to the contour of the insole insole. Plate 7 has thickness of the relief trough equal to the thickness of

insoles 9. Thereafter, the top is tightened by moving along the X axis of the exact part of block 4, followed by drawing the top along Y axis (Fig. 1) by embossing the insert insole into the pad track with the help of a punch 6 (Fig. 3), which has a relief opposite to the relief of the plate 7. Then the half-matrix 5 closes, fixing the top of the shoe in the closed state (Fig. 4), the punch 6 is retracted to a predetermined thickness of the sole and the casting of the sole

8. After the casting sole has cooled down, the shoe is removed from the molding pad and an insole 9 is inserted (Fig. 5), and due to the relief ridges 11, cavities 10 are formed under it, which can improve the hygienic properties of the shoe,

Example. Cast shoes are made of injection molding method of attachment. A bulk blank is assembled consisting of a velor top and a set-in textile insole from a kersey. The workpiece is subjected to wet-heat treatment at 60-70 ° C for 15 s. Then the top is drawn on the casting shoe with a trace that has a nodule beam and In these regions there is a wave-like relief, the crests of which are placed parallel to the contour of the insole, the height of the crests was 5 mm and the pitch was 15 mm. Then, before closing the semi-matrix of the injection molding machine, additional top drawing is carried out by means of the relief molding of the insole with the help of a punch having - Moelastoplast.

The use of the invention will improve productivity by combining the process of forming the top and pouring the bottom on one

In addition, the additional stretching of the workpiece will allow using not only readily formed textile materials, but also leather as the top material.

Invention Formula A method of manufacturing an injection molding shoe method consisting in sewing a bulky billet consisting of a top and a set-in insole that is smaller than the footprint of the shoe, putting on and shaping the billet on the molding block, closing the semi-matrix of the mold and making the sole different from that the goal of increasing labor productivity by eliminating the preforming of the shoe upper from difficult-to-form materials on the tightening block and improving the hygienic properties of the finished shoe before the closing operation Neutral matrices carry out additional stretching of the bulk billet by means of the relief molding of the inner sole by means of a profiled pad trace, which has a wave-like relief in the sock-tuft and gelenochnyi parts, the crests of which are placed parallel to the insole’s contour, and the relief of the punch having the relief of the reverse relief, the trace of the insole, and the pressure of the punch having the relief . ///////////////////////./77 m figure 1 FIG. 2 FIG 3 8 2 FIG. five eight FIG 4 If FIG b
