Abstract

FIELD: manufacture of building materials. SUBSTANCE: the offered mold has exterior and middle side members attached to flexible cross-members. Cells with flexible bottom, separating and end-face walls have supports engageable with side member supports. Exterior side members interconnected by tie-rods provided with clamping wedges. Installed on exterior side members are brackets with chamfer whose angle equalling the angle required for turning of exterior side members to remove forms. Secured to brackets are loops in which bars are installed. Bars are engageable with supports of middle side members and limiting the turning of exterior side members and displacement of middle side members in removal of forms. To assist in handling the mold, its slinging journals are installed so that their axis is located between center of gravity of mold with articles and center of gravity of mold without articles. EFFECT: simplified design, reduced labor input in removal of forms, and higher productivity. 3 cl, 6 dwg

Description

 The invention relates to equipment for the production of building products.

 Known cassette form, including the frame, the sides, a flexible pallet with dividing walls and shaped cams for bending the pallet when stripping [1] However, the design of this form provides for capacity, and therefore the performance of the form. In addition, the need for individual removal of each product from the mold is associated with increased complexity of formwork.

 The technical solution closest to the claimed and adopted as a prototype is a device for the manufacture of reinforced concrete products, including cassettes with a flexible pallet, middle and outer longitudinal and end sides, as well as swivel pads with smooth and curved supporting surfaces, levers, hinges, connecting and other elements [2] The device provides a multi-row arrangement of products. However, the use of swivel pads, levers and other elements for the forced extension of the cassettes and the displacement of the sides when stripping, complicates the design of the device. Remaining increased and the complexity of formwork, due to the need for individual removal from the device of each molded product.

 The problem solved by the invention is to simplify the design of the form, reducing the complexity of formwork, increasing productivity.

 The task in the proposed design is solved due to the fact that the mold for the manufacture of piece goods, containing cassettes with a flexible pallet and dividing walls, outer and middle sides, as well as trunnions for slinging the form, is equipped with flexible crossbars on which the outer and middle sides are fixed. The outer sides, in addition, are interconnected by rods provided with clamping elements, such as wedges. Cassettes and sides are equipped with interacting supports to prevent falling out during tilting of the mold. In addition, the outer sides are equipped with brackets with a bevel, the angle of which is equal to the angle of rotation of the outer sides required for stripping. Hinges are attached to these brackets, in which the rods are placed, interacting with the supports of the middle sides. The common axis of the pins intended for slinging the mold extends between the center of gravity of the mold with molded products and the center of gravity of the mold without the mold.

 Thanks to the fastening of the sides on flexible crossbars, the sides are opened when the form is dismantled (after turning it over and the wedges are unlocked) when the form is lifted automatically, under the influence of the moment created by the slings on the cantilever pins of the form, which eliminates the mechanism of the side displacement to separate them from the hardened products. The extension of the flexible pallets of the cassettes is also carried out directly under the influence of the mass of the cassettes themselves and the mass of the products in them, since in the proposed design of the form, the direction of the extension of the pallets coincides with the direction of the force exerted on it from the mass of the cassettes and products when stripping. Consequently, there is no need for swivel pads for the forced extension of the pallets. The exclusion of the mechanism for displacing the cartridges and sides, as well as the swivel pads for the extension of pallets simplifies the design of the form. In addition, since the formwork of the proposed form is carried out after its turning, and the sides are opened and the cartridges are deflected downward, the products after the formwork and lifting the form with slings remain on the floor (or on the transport pallet). Thus, the operation of removing products from the mold and their installation is excluded, which reduces the complexity of the formwork. And since when lifting the mold it is released from all products at the same time, the formwork time is also reduced, which increases the productivity of the mold.

 In FIG. 1 shows the proposed form, a top view; FIG. 2 section along AA in FIG. 1 (in this and subsequent figures, the shape is depicted on a larger scale); in FIG. 3 a section along BB in FIG. 2; in FIG. 4 is a view along arrow B in FIG. 2; in FIG. 5 is a view along arrow B, in the formwork stripping position; in FIG. 6 cross-section along DG in FIG. 5, also in the stripping position.

 The form contains the outer 1 and middle 2 sides mounted on flexible crossbars 3. Between the sides there are cassettes 4 freely lying on the crossbars 3 with a flexible pallet 5, dividing 6 and end walls 7. On the end walls 7 of the cassettes 4, supports 8 are strengthened. The sides 1 and 2 are equipped with supports 9 and 10, respectively.

 The outer sides 1 are interconnected by rods 11 provided with clamping elements, for example, wedges 12. Brackets 13 are mounted on the sides 1 with a bevel at an angle α equal to the angle of rotation of the side 1 when stripping. Hinges 14 are fixed on brackets 13, rods 15 are freely placed in these loops.

 The pins 16 are mounted on the sides 1 in such a way that the common axis of the pins 16 extends slightly below the center of gravity of the mold with the products in it, but above the center of gravity of the mold without the products. These centers of gravity do not coincide, as some parts of the mold are asymmetrical relative to the geometric center of the product : pallet 5 and crossbeams 3 are located below, so the center of gravity of the form is located below the center of gravity of the products. Slings 17 of the lifting device (not shown) are designed to lift the form.

 In the initial position, the shapes of the wedges 12 are lowered, so that the cassettes 4 are sandwiched between the sides. After filling out the mold and hardening the products, the mold is lifted by the slings 17 by the pins 16, they are turned upward by pallets (the location of the center of gravity of the mold with the products above the axis of the pins provides such a turn without effort) and lowered to the floor or onto a transport pallet (not shown). The inverted form is unlocked by lowering the wedges 12, for example, by hammer blow. Then slings 17 form again raised. Since the force of the slings 17 is applied cantilever to the sides, then a moment is created on these sides, under the influence of which the sides 1 rotate at an angle a (Fig. 5), exfoliating from products in the form. In this case, the brackets 13, turning together with the sides 1, come with their base in contact with the rod 15 located in the loops 14, as a result of which the rotation of the sides 1 stops. With further lifting of the lines 17, the flexible cross members 3 under the influence of the weight of the sides 2, cassettes 4 and the products in them bend down until the supports 10 of the sides 3 fall on the rod 15. The sides 2 are set to the position shown in FIG. 5, and the cassettes 4 under the influence of their own mass and mass of the products bend down (Fig. 6), providing a free exit of products from them. Thus, all products are automatically released and remain on the floor or on the transport pallet.

 Since the center of gravity of the inverted freed form is higher than the axis of the pins 16, the form automatically rotates to its initial position when it is further raised, the cassettes 4 again lower on the cross member 3, the sides 1, under the influence of a moment now in the opposite direction, also turn to their original position, wedges 12, under the influence of their own mass, fall, fixing the closed position of the sides. The form returns to its original state, and the cycle repeats.
