SU1253594A1 - Last for internal moulding of footwear of the stocking type - Google Patents

Description

The invention relates to a shoe industry, namely to pads for carrying out internal molding of stocking-type footwear in process equipment on automatic or semi-automatic footwear production lines.

The purpose of the invention is to simplify the structures and improve the quality of the molding.

Figure 1 shows the sliding block, the general view (the contour line shows the open position of the block, the dotted one is closed); Fig. 2 is a section A-A in Fig. I of the sliding shoe, perpendicular to the cutting plane.

A shoe for internal shaping of a shoe tina stocking consisting of a toe 1 and a full 2 parts and a connecting unit placed between them, having a slide 3, a guide 4, each of which has a working contacting surface, the cross section of which forms an arc of a circle, and means to move along the arc of one part of the block relative to the other, mounted on the movable part of the block. The connecting node in the plane of the connector has the shape of the corresponding section of the pad. An earring 5 is attached to the right part of the pad, which enters the means for moving along the arc of one part relative to the other and is connected to a corresponding drive.

A block for the internal molding of stocking-type shoes works as follows.

The force from the actuator is applied to the stud 5, with the exact 2 part of the pad, together with the slider 3, moving along the guide 4, the hinge block along the length.

A shoe upper is put on the closed shoe for molding. Further, by applying force to the lug 5, the starting position of the exact 2 part of the pad is moved, the slider 3 of which slides along the guide 4 provides the movement trajectory of the exact 2nd part of the shoe, the curvature of the guide the working contacting surface, divides the block into movable and stationary parts, the cross section of which forms an arc and which are rubbing surfaces when moving the movable part of the block 2, in the process of forming preparation

The method of manufacture pads.

The pad is prefabricated on a copy machine. It is then cut, for example, by an arc cut into two parts (toe and heel). The location of the cut is chosen according to the accepted design of the sliding block.

The height of the layer of material removed at the same time by the cutting tool is equal to the total height of the combined (inserted one into the other) parts of the slider - guide. Next, to the obtained parts of the block (toe and foot) directly to the arc planes, respectively, the slider and the guide are attached. The width of these parts is equal to the width of the pads in the plane of the connector. Next, the slider is inserted into the D / 1 I guide to ensure the assembly of the toe and heel parts of the sliding block.

The manufacture of the pad is completed by machining the side surfaces of the slider and the guide protruding beyond the body of the pad to form a single surface of the pad.
