Description

The invention is intended for the manufacture of shoes with a multilayer sole, for example, from a mold. A device for manufacturing shoes is known, comprising a mold with a matrix and a lower movable molding in it, a trail punch, a drive for reciprocating movement of the punch in the matrix, and an associated block 1 mounted above the matrix on the swivel head. In the known device, there are no means of forming an intermediate sub-granular layer connecting the workpiece-ankle to the outer base layer on the surface opposite to the surface of the track, therefore this device does not provide for the manufacture of multi-layered footwear. In order to manufacture shoes with a multilayer base, the proposed device is equipped with a counter punch mounted on the swivel head. The counter punch is provided with a seal installed along its perimeter and interacting with the die. In the oncoming punch, the expansion channels are filled. FIG. 1 shows the proposed device, a general view; in fig. 2-5 the same, longitudinal cuts. The shoe making apparatus comprises a mold with a die 1, in which the lower, track forming punch 2 is movably mounted, connected with the drive of its reciprocating vertical displacement, and the swivel head 3 with a pad 4 and a counter punch 5 that are mounted above the press form and mobility 1 relative to it. Gating channels are made in the matrix 1 for injecting a moldable material, at the outer ends of these channels there are movable dampers 6 for closing them. On the forming track poopsone 2, an undercut is extended in along its perimeter to hold the workpiece. On the opposite punch 5 installed around its perimeter seal 7 and vypolneny vypolnye channels g. The device operates as follows. The counter punch 5 is installed in the matrix 1. An area of the side surface at the level of the gating channel b c forms a forming cavity with the track forming punch 2, communicating with

the device for feeding the material through the gating channel l i

A melt is injected into the forming cavity through channel A, and the bottom (see, fig. 2) of the first (outer) layer is molded while moving the punch 2, while 6 intersects the end of the sprue channel, In another case (see, fig. 3) when molding the first (outer) sole layer, the initial position of the punch 2 is retained and the forming nojiccTb is co-fed with the sprue channel;

After the outer layer of the base layer is molded, the counter punch 5 is removed from the die 1. By turning the head 3, the pad 4, and of which the workpiece boot 8 is placed, is brought to the working position. The molded cavity formed by the preform 8 and the outer preform of the first layer of the base, BO, is melted. After this, the valve 6 closes the channel S and, a friction of the second - inner layer of the sole takes place.

At the end of the gai vulcanization of the product is removed from the mold.
