The purpose of the invention is to improve the quality of the cast grid by equalizing the temperature along the length of the grid forming zone. The mold contains a drum 1 with 2 longitudinal and transverse 3 grooves and a feed pad 4 in contact with the drum and having a sprue channel 5. The distributor 6 of the melt located coaxially in the tube 7 is located in the gate channel. The outer pipe 7 has holes 9 located above and below pipes, and plugged on the supply side of the melt, and the distributor 6 - on the opposite side. 1 hp f-ly, 3 ill.

Description

i The invention relates to a foundry industry, namely to the continuous casting of lead leads SK-to | umula tors.

I The purpose of the invention is to improve the quality of the cast grille by equalizing the temperature along the length 4 of the grid formation, I FIG. 1 shows the proposed 5 device, a general view; FIGS. 2-11, A-A cut of a la figs. one; in fig. 3 - feeding block from the side in contact with the drum, I The device contains a drum with m rod and 2 and transverse grooves 3, feeding block 4, contacting with the drum and having a sprue channel 5. The casting channel contains a melt distributor 6 that The pitch is located coaxially inside the pipe 7 and is connected to it by the supply pipes 8 connected to the litnic channel. The pipe 7 has holes 9, made above and below the nozzles of a vertical plane, symmetrical to the axes of the longitudinal grooves on the bar (the hole. The holes of the pipe and the feeding pipes are located in the cavity of the litnic channel: opposite to the flow of the melt, has a cap Yu. The pipe 7 from the feed side of the melt has a plug P,

The proposed device works

in the following way,

; Before the casting is started, rotational movement of the drum 1 is given. During the pouring process, the overheated melt, in quantities larger than necessary to form the grid, is fed from the furnace to the distributor 6, where it goes through the sprue feed channel 5 and fill it. The melt part hardens in the longitudinal 2 and transverse grooves 3 of the drum in the form of an accumulator spar. e shown) for heating to the required temperature and to return to litnikovsh kana proposed device. Thus, the melt movement along the gating channel is eliminated, and its forced movement remains only along the height of the drip. It provides

It has uniform temperature and hydrodynamic conditions for the formation of 1P; n lattices along the entire length of the formation zone.

The proposed design of the device allows stably obtaining high-quality grating in a fairly wide range of technological process modes of casting due to the organization of melt movement in the zone of casting formation, which prevents the melt flow along the drum surface within the casting channel, which creates the same temperature conditions over the entire length of the formation zone.

Example, A device is made for the continuous casting of lead current leads. To pour starter wires. Batteries made a twelve-seater drum of cast iron with a diameter of 548.5 mm and a width of 230 mm, which, complete with a shaft and bearings, is mounted on a welded frame. A DC drive is mounted on the same frame, which provides the drum with a smooth output for a given rotation mode. On the bed there is a bronze power supply. a boat which is pressed to the drum by means of a screw mechanism. In the feed block on the surface in contact with the drum, there is a gutter channel in the form of a hollow groove, the length of which is O mm greater than the width of the battery grid and equal to 145 mm. A tubular distributor is mounted in this groove, consisting of two coaxially arranged pipes: an outer diameter 28 with an inner diameter of 14 mm. The pipes are interconnected by eight nozzles with a hole diameter of 3.5 mm, which are evenly spaced along the length of 112 mm. B the outer pipe under and above the nozzles drilled in 8 holes with a diameter of 2.5 mm.
