Description

And: i (.ID company doesn’t belong to anddifferentiation) of the first reinforced concrete, namely, pipes of a large length of vertical lines} П) 1 m by molding with immediate dismantling.

The purpose of the invention is to reduce the labor intensity and the lack of convenience in the assembly and disassembly of the mold.

Fig. 1 shows the mold for making tubular concrete products, a general view; in fig. 2, section A-A in FIG. one; in fig. 3 node 1 in FIG. 1; in fig. 4 is a view B in FIG. 2

The mold for the manufacture of tubular concrete products consists of two half-molds 1 and 2 connected between elastic locking strips 3 connected through a hinge 4 by hinged longitudinal rods 5, set in motion by the locking mechanism 6, the pallet 7 and the core 8. Each of the half-molds 1 and 2 is equipped with three rotary eccentric-1 and 9 stops with a variable radius (two positions are shown in Fig. 3: closed and dotted open) and springs 10. pressing them to the pallet 7; - matte Ami 11, and the half-form 2 - brackets 12.

The principle of operation of the proposed form is as follows.

The molded article with half-molds 1 and 2 and the tray 7 is transferred to a steam chamber. When the mechanism 6 of the locking device, having the right and left threads, is moved along the vertical arrows (Fig. 1 and 4), the hinged brackets 5,

Mepnga up, the hinge t ha 5 carries aa elastic straps 3, which in turn move through the hinges 4 brackets 1 and 12

horizontally along the arrows to the sides - half-molds 1 and 2 open. At the moment of opening, the rotary eccentric stop 9 is pressed by the spring 10 to 7. Radius

by the value (V (Fig. 3). Half-form I, moving horizontally along the arrow, rolls on the rotary eccentric support 9, and the rolling radius, constantly increasing, raises the half-form 1 and the value where and simultaneously occurs - shift and separation of the plane half molds 1 from a raw product, which significantly reduces the effort

uncover.

The diluted half-molds 1 and 2 are removed from the product and installed on the next pallet 7. The eccentric stop 9 is rotated downward by a large radius R down under the action of the spring 10, thus the half-molds 1 and 2 are raised above the pallet 7 by the value of $. g 5 down the arrows by the mechanism of the locking device the hinges 4 are diverted in the horizontal direction, the brackets 11 and 12 are carried away, the opening of the half-molds 1 and 2 in the hinge places is achieved by the elastic strips 3. The half-shapes i and 2 are closed, crossed, - melting zkstsentrikovyh on the abutments 9 and lowered on a pallet 7, their simultaneous samofiksadi along the outer edge of the pallet 7.
