in the sleeves 4, mounted on the pallet 1 at an angle to its center. The lugs 3 are placed on the upper plane 7 of the pallet. When laying and hardening the mixture, the rod 5 is in the lower position; when dismounting, the rod abuts the base and rises, while due to the inclined arrangement of the sleeves 4, the bead 2 moves up and back, resting on the rod and the end of the eyelet 3. In this case, the product is released from the beads and removed from the form. After transferring the form to the post styling mixture of the bead 2 are closed under the action of its own weight. 4 il.

The invention relates to the production of products from precast concrete and can be used in the manufacture of plates, panels and other products in steel forms.

The purpose of the invention is the provision of automatic stripping;

Figure 1 shows the form, top view: figure 2 - form with a closed side; on fig.Z - form at the time of stripping; 10 Fig, 4 - section aa a nz figure 2.

The form contains a pallet 1 and connected with it by means of brackets, folding sides 2, having lugs 3 for hinge mounting brackets. Pod- 15 don 1 is equipped with guide sleeves 4 located at an angle o. to his. the center, and each bracket is made in the form of a rod 5 placed in the guide sleeve 4 and provided with a movement limiter in the form of a pin 6, while the lugs 3 are placed on the upper plane 7 of the pallet. The bracket is fixed in the eyelet 3 with fasteners 8-10.

The form for the manufacture of concrete products works as follows.

When laying, vibrating and heat treating the concrete mix, the beads 2 are closed, the rod 5 is in the lowest 30 position. Moving or ascending the side when laying the concrete mixture is impossible, since with the locks 11 of the form closed, the rods on the opposite sides are tilted in opposite directions.

During the installation of the mold to the post of demolding, the rods under the influence of the weight of the mold are moved to the highest position. Since the sleeve 4 is set 5 at an angle to the center of the pallet, the board moves up and back and releases the product for removal, resting on the rod 5 and the end 12 of the eyelet 3. After removing the product, the form is set to the next post, and the sides are automatically closed weight. After cleaning and lubrication, the mold is ready for the next molding. When changing form on products of various dimensions, the guide bushings are welded in the required place, while the existing ones are jammed.

Automatic stripping and mold assembly provides increased productivity and reduces the labor intensity of the formation of products.
