Abstract

A mold for vulcanization of annular polymer products containing semi-cylindrical end forming elements installed with the possibility of relative movement, parallel-arranged interchangeable straight line forming elements interconnecting the end elements between them, the mechanism for separating the form and the mechanism for locking the form, characterized in that in order to simplify the construction of the form and its service, the straight forming elements are made with T-shaped grooves on the side facing the center of the form Onah, and the mechanism for locking the form is made in the form of sliders with wedge side edges mounted for movement in a direction perpendicular to the ends of the shape, with T-shaped protrusions on the side edges of the sliders for engaging with the T-shaped grooves.

Description

The invention relates to the manufacture of ring polymer products and is intended to form and cure endless belts.

The aim of the invention is to simplify the design of the mold and its maintenance.

Figure 1 shows the shape of the cross section: figure 2 is the same, top view; on fig.Z - section aa in figure 1: on figure 4 and 5 -. form in the process of vulcanization of belts.

The mold for vulcanization of ring polymer products contains semi-cylindrical end forming elements 2 and 3 mounted on frame 1 with relative movement, parallel replaceable straight linear forming elements 4 and 5, and a mechanism 6 for form dilution. The outer working surface of the elements 2-5 is made in accordance with the shape of the product.

The straight forming elements 4 and 5 are made with T-shaped grooves 6 on the sides facing the form center. The mold has a mechanism for locking the mold, which is made in the form of sliders 7 with wedge side edges mounted for movement in a direction perpendicular to the ends of the mold. In this case, T-shaped protrusions 8 are made on the lateral faces of the sliders for engagement with J-shaped slots 6.

At the ends of the rectilinear elements 4 and 5, steps 9 are made to center the end elements 2 and 3.

When using the shape of its frame 1 can be mounted on the axis 10 for rotation.

The form works as follows.

By means of the mechanism b for breeding the form, the end forming elements 2 and 3 are set at a predetermined distance from each other. Then, straight-line shaping elements 4 and 5 are installed, the steps 9 of which mate with the side edges of the end elements 2 and 3, and with the help of

Sliders 7 form locked. Here, the horizontal gaps are selected and the forming elements 2-5 form a closed forming surface on which the workpiece is assembled.

After the product blank is assembled, the pressing chamber 11 and the body 12 or plates 13 and sidewalls 14 are superimposed on the mold and the product is molded and vulcanized with heat and pressure. After vulcanization, the mold is disassembled in reverse order.
