Abstract

The invention relates to equipment for the manufacture of products from composite materials by the method of pressing. The purpose of the invention is to improve the quality of crimping. To do this, the two half-shapes 1, 2 have sides 10, 11, made with thinning 12, 13, forming an elastic hinge in the zone of greatest curvature of the shaping surfaces, and the surface 5 of the connector is located on the upper 6, 7 and lower 8, 9 sides of the half-shapes. When the equipment is crimped in the vertical direction, the half-molds 1, 2 come closer to each other, providing a gauge in the transverse direction, i.e. comprehensive compression. 1 il.

The invention relates to equipment for the manufacture of articles from composite materials by the method of pressing molding, namely to molds.

The purpose of the invention is to improve the quality of crimping.

The drawing shows the proposed tooling.

j The tooling consists of half-molds 1 and with shaping surfaces: and 4 and a surface 5 of the connector located on the top 6 and 7 and bottom and 9 sides of half-molds 1 and 2. On the 5-side sides 10 and 11 half-molds 1 to 2 are thinned 12 and 13, about 1) the elastic hinge in the zone of the greatest (5 curvature of the forming surfaces 3 and 4. The surface 5) of the connector is made with a thrust surface: 14, the equipment is placed in a vacuum bag 13.

The rigging works as follows.

The workpiece is placed in the base and the mold halves 1 and 2 are closed. The vacuum bag 15 is touched and the assembly is placed into an autoclave (not shown). The pressure of the working medium affects "and the upper 6 and 7 and lower 8 and 9 are

RONA popup 1 to 2; and presses the workpiece in the vertical direction. In this case, the thinning 12 and 13 of the lateral sides 10 and 11, which form the elastic hinge, ensure the convergence of the half-molds 1 and 2 between the robe, which presses the workpiece in the horizontal direction. The specified size of the workpiece and the degree of crimping ensures the presence of resistant surfaces 14.

The proposed equipment ensures BcectopoHHee compression of the workpiece, which improves the quality of pressing.
