SU60020A1 - Sandals Sole Mold, etc. - Google Patents

Description

The proposed mold for the manufacture of sandals soles, etc., made in the form of a punch and a die, is intended to simultaneously fasten with the bottom of the shoe during the vulcanization of the insole, heel, diaper, and loop for the top (belt).

For this, the matrix is provided along the contour of the insole with sockets into which the loops for the belt are placed, and on the track with pins for fastening the insole with the heel and the heating pad.

In FIG. 1 shows a longitudinal vertical section of a mold for making the soles of sandals, etc .; FIG. 2 is a cross section of it according to AA in FIG. one; FIG. 3 - the same on BB of FIG. one; FIG. 4 is a front view of a simple loop; FIG. 5 is a side view of it; FIG. 6 - its top view; FIG. 7 is a front view of the hinge; FIG. 8 is a side view.

The mold is made in the form of a matrix 1 and a punch 5 (fig. 1-3), nmeyush, their pre-shaped shaped groove, exactly corresponding to the contour of the sole of different types of shoes on an average and low heel. The matrix is provided along the contour of the insole with nests 2 for stirring metal loops for threading the top (remi).

To install the metal wadding 6 and fasten it with the insole 7, as well as to form a hole in the heel part of the insole, which is used for precise installation of the wooden heel and its attachment, the matrix is equipped with pins 3.

For the manufacture of sandals soles and the like, a rubber mixture is pre-prepared in the usual way, which is calendered to the required thickness (4-4.5 mm) and cut from it by cutting the sole blanks for vulcanization, as well as blanks for the heel.

The main insole is made of dubbed fabric, for which, before dubbing, the fabric is smeared with a rubber mixture on a spreader calender or other method. The main insoles are cut from the duplicated three layers of the fabric with the appropriate size of the cutters. The blanks prepared in this way for parts

Kiza: soles, insoles, and for some types of shoes and heels are put into the molds for the purpose of repairing the bottom of the shoe insoles 7, heel 9, gelenkm 6 and loops 4 during vulcanization time.

The laying of the prepared elements into the mold for their vulcanization and vulcanization of the metal loops and the diaper is carried out as follows. Firstly, a blank of the main insole 7 is laid, which is centered on the pins 3 serving to center the metal diaphragm B. After this, metal loops 4 of the structure shown in FIG. 4-8. One end of these loops, having holes all over the surface, is located on the main insole, and at the same time it is laid; the electric heel 6, which is centered on the pins. Then, the workpiece 8 of the base sheet is laid, and for low-heeled shoes and shoes on rubber with a wooden insert, the workpiece for the heel is also 9. The position of the bottom elements in the mold is shown in FIG. I-3.

The vulcanization of the elements incorporated in this way is carried out in the usual manner. Pvvulkanization rubber mixture goes into the holes of the hinges 4, firmly fastened them with the sole.

After cooling, the burrs are trimmed, and then the insole is glued in. Footwear fastening on the leg is made with a band through the loops. When applied to the top of the shoe, the LEATHER last is fastened to the loops with the help of special braces.

Subject and purpose

and

A mold for making the soles of sandals, etc., made in the form of a punch and die, is made so that, in order to simultaneously fasten with the bottom of the shoe during the vulcanization of the insole, heel, toweling and loops top (belt), the matrix 1 is provided along the contour of the insole with nests 2 for holding loops 4 in them, and on the next - with clips 3 for fastening the insole with the heel and heat pad.
