FIELD OF THE INVENTION The invention relates to the electrical industry and can be used in the manufacture of (lead batteries

The purpose of the invention is to reduce the marriage.

Fig) shows the device, General PID; Fig. 2 shows a section A-A in FIG. with the placement of a belt pushed out through the groove of an imprint of the grids; on shl.Z and 4 - section bb in fig (variants of splines in the grooves of the form imprints and placement of the belt on the pusher); FIG. 5 shows a variant of the device in which one half-form is made in the form of a drum; Fig. 6 shows the B-B expression in Fig. 5 (a variant of the arrangement of the ejector imprint on the grooves of the lattice impression); figure 7 - location of the ejector in the form, top view

The device contains half-molds 1 and 2 ;, the extractor 3 and the pulling roller 4 with One half-form is made in the form of a drum and has imprints of a solution. The other half-form can be made in the form of a moving drum or a sub-element that does not have lattice imprints. brushes are formed by grooves 5. Mutual intersections of splines are made on the cylindrical surface of the drum and in pa $ ah prints 6. Slots can be PERFORMED in the grooves of prints both in view i, e, the extension of their profile, and in the separate profile code, made - yogo at the bottom of the grooves

Life: the ticker is made in the form of an e-wind belt made, for example, of steel grade 45 or other heat-resistant material with a low coefficient of thermal expansion. The endless ejector belt is placed in the splines of the drum and is pulled on against the roller. Innovated with rotation. Noluforg Y are equipped with a cooling agent supply system

The annular slots are located on the lattice vice along the grooves forming the lattice contour-i, for example, along the crosspiece of the dual lattices and along the side walls with a ushkakkk.

P1LI; LY and the corresponding belt can also be located on each continuous vertical groove of the impression of the grids, through one groove - two, etc.

four

with casting lattices 5 consisting of vertical and horizontal veins. When casting grids with openwork vein configuration, the vents can be pressed into all grooves of the print and the cylindrical surface of the drum; then the ejector belt is stencilized in the form of a stencil, respectively, the impression of gratings. The semi-molds are made, for example, of cast iron of grade SCH-20 "

The device works as follows

The cooling agent is supplied to the half-molds. The cooling agent consumption is taken equal to 1.2-2.0. Then the drive is turned on. The rotational movement of the drum 1 is reported at a linear speed of 20-25 m / s. Together with the drum, the belts of the ejector 3 moving over the rotating roller 4 are moved. After that, lead melt is fed between the molds from the top at a temperature of 360-380 ° C. The lead melt falls between the cooled molds, quickly crystallizes and forms a lattice print on the drum

When casting an impression of a half-mold, lead melt fills a predetermined impression depth corresponding to the thickness of the lattice. Due to the viscosity, the lead melt does not enter the gap.

between the belt of the ejector and the walls of the splines, which is 0.03-0.15 A strip of gratings, the exit from the joint area of the half-molds, is simultaneously separated by a belt of the ejector from the impressions of the half-mold, the separation of the strip is carried out continuously. After casting, the gratings are cut.

The proposed device allows separating the lead battery grids with the help of an ejector in the form of an endless belt without deforming and violating the integrity of all the veins of the grid, and, as a result, reducing scrap.
