Изобретение относитс к области строительства и может быть применено в технологических лини х, оборудованных механизмами дл автоматического открьюани бортов форм.The invention relates to the field of construction and can be applied in technological lines equipped with mechanisms for automatic opening of the sides of the molds.

Известна форма дл изготовлени строительных изделий, включающа поддон, на котором закреплены с помощью шарнира поворотные борта и установлен передвижной борт, при один из поворотных бортов соединен с передвижным бортом регулируемыми по длине т гами, один конец которых выполнен в виде сектора шара с радиусом, равным не менее трехкратного рассто ни от центра шарнира до передвижного борта.The known form for the manufacture of building products, including a pallet on which the swivel flanges are fixed by means of a hinge and a movable side is mounted, with one of the swivel beams connected to a movable flange by adjustable length rods, one end of which is made in the form of a sector with at least three times the distance from the center of the hinge to the movable side.

Недостаток этого устройства - необходимость применени приводов большой мощности дл обеспечени усили в т ге дл отрыва борта от издели .A disadvantage of this device is the need to use high power drives to provide effort to pull the bead from the product.

Известна также форма дл изготовлени строительных изделий, наиболее близка к предложенной, содержаща поддон с поворотными бортами и внутренний борт, кронштейн которого кинематически св зан при помощи рычажной системы с кронштейном одного из поворотных бортов.Also known is the form for the manufacture of building products, which is closest to the proposed one, containing a pallet with swivel sides and an inner side, the arm of which is kinematically connected by means of a lever system with the arm of one of the slewing sides.

Недостатком данной конструкции вл етс больша мсщность приводов, примен емых дл открывани бортов, что затрудн ет распалубку.The disadvantage of this design is the large capacity of the drives used to open the sides, which makes stripping difficult.

15 a pallet with swivel flanges and an inner side, the arm of which is kinematically connected with the help of a lever system with the bracket of one of the swivel sides, the lever system is made with a hinged double joint. NIKOM, the upper end of which is fixed on the bracket of the inner bead, and the lower one is supported on the pallet and connected by means of a ty with the cromptee of the pallet. FIG. 1 shows a form, a plan view; in fig. 2 shows section A-A in FIG. 1, in FIG. 3 is the same in terms of FIG. 4 - the same, at the time of separation of the bead from the product; in fig. 5 is a section BB in FIG. 2; in fig. 6 is a sectional view BB in FIG. 5. The form contains a pallet 1, on which the hinge fixes the outer. Swiveling beads 2 from the bracket 3 and the inner bead 4 with the brackets 5. Each arm 5 is kinematically connected with the bracket 3 by one of the turning sides 2 and consisting of a hinged bead 2 pivotally connected to the crown by the matte 3, by means of a 6 ni 7 ball, and with the help of a hinge 8, with a bracket 5, an inner rail 4. At the same time. the hinge 8 is installed a hinged double link, the upper end 9 of which is fixed by hinge 10 to the bracket 5 on the inside side, and the lower end I1 is supported on the pallet 1 and is connected to the bracket 14 of the pallet 14, and 13 are connected to the brackets 14 of the pallet 1 by means of ball screws 15. In the bracket 5 of the inner bead 4, a groove 16 is made to ensure the free movement of the hinge 8 with horizontal movement. The device operates as follows. When the drive is turned on (not shown) with the help of devices for automatic opening and closing, the outer bead 2 rotates around the hinge connecting it with the pallet 1. In this case, the force is transmitted through 7 to the hinge 8, which is full, horizontally moving into the groove 16, rotates the ends 9 and 11 and the ti gi 13 of the hinged d-link. At the initial time, the thrusters 13 with the hinge 15 abut against the bracket 14 of the pallet I, and the ends 9 and 11, connected by the hinges 8 and 12, abutting the hinge 12 against the pallet 1, turn to take an upright position. At the same time, the ends 9 and 11 of the articulated two linkage are acted on by straps 7, also helping to occupy the vertical position. In doing so, raising the hinge 10, which is rigidly connected to the inner side 4, is lifted and detached from the product under the action of the vertical component force. Then, with further movement of the ring r. 7, the inner bead 4 is lifted and rotated around the hinge 15. The sides 2 and 4 are closed in the reverse order. The invention The form for the manufacture of building products, containing a pallet with swivel boards and an inner side, the arm of which is kinematically connected with the help of a lever system 1 with a bracket of one of the turn sides, which is designed with a hinged link, the upper end of which is fixed on the bracket of the inner side, and the lower support on the pallet and connected by means of cable to the bracket of the pallet.
