Description

The invention relates to the field of plastics processing and can be used for the manufacture of products by methods of sealing and foaming of foaming polymeric materials.

The purpose of the invention is the expansion of the technological capabilities of the mold in the manufacture of products from foaming materials.

FIG. 1 shows a form with adjustable pasMepaiviH, look species; Fig. 2 shows the arrangements of the side walls of the mold; in fig. 3 - form, top view; in fig. k - section A-A in FIG. 3 (conventionally not shown in t ha); - in FIG. 5 - section B - B in FIG. H; in fig. 6 shows section BB, in FIG. 3

- The form contains the base plate 1j, the cap 2, forming with them the cavity-forming side walls -3; interconnected in a closed loop by means of a fastening unit, the connection being made so that one of the ends of each side wall is adjacent to the adjacent wall and can be moved along it, and the other end with a part of the wall is protruding; forming cavity. In this case, the mating ends of the side walls are made obliquely on the outside and have bevels 4, the mount assembly is made in the form of a G-shaped bracket 5, one shoulder of which is hinged on one side wall 3 at its mating end by floating pipe. axis 6,

installed in the groove 7 of this wall with the possibility of free movement. The other shoulder of the L-shaped bracket 5 is fixed on the protruding part of the adjacent side wall by means of a detachable connection in the form of a fastening bolt Z. / mounted in the groove 9 of the bracket and screwed into the threaded hole made on the protruding part of the wall 3. The one part adjacent to the end face The side wall and the protruding part of the adjacent side wall are additionally connected to each other by a length 10 adjustable thrust.

The form works as follows.

On the base plate 1, the required quantities of side-wall 3 are installed in such a way that the end of the wall, made with bevel 4, is in contact with the projecting part of the adjacent wall. The pre-installation of the side walls 3 is made by fixing the L-shaped bracket 5 on the protruding part of the wall with a Momji fastening bolt 8 installed in the bracket groove 9. After pre-installing the side walls, the final fixation of the shaping cavity is made by adjustable length rigid rods 10. The same Sealing of the mold cavity is also provided.

The disassembly of the mold after the product is made is carried out in reverse
