Abstract

The invention relates to foundry, in particular to casting in metal molds. The purpose of the invention is to improve the quality of castings. Filling-feeding device contains a rotary around the horizontal axis of the dispensing furnace 1, equipped with a capacity of 8, having a filling neck 9, covers 6 with sprues channels 7 and molds 4 and 5 installed on the covers 6. Capacities are made with openings 10 and 11, in which the branch pipes are located having a drain 13 and an intake 14 parts. Each nozzle is placed in the neck with its own drain part, and the intake pipe - in the cavity of the tank 8 parallel to its bottom and connects the cavity of the tank with the sprues of the lids. The length of the discharge part of the nozzle is equal to the length of the neck. 2 Il.

Description

The invention relates to foundry, in particular to casting in metal molds.

The purpose of the invention is to improve the quality of castings.

FIG. 1 shows the device, a general view; figure 2 - the same, in a different position.

Filling-feeding device contains a dispensing furnace 1 installed rotatably with the help of drive 2 around a horizontal axis 3, and casting molds 4 and 5 mounted on covers 6 with runner channels 7. The dispensing furnace is provided with a container 8 made with a filling neck 9, necks 10 and 11 and heaters 12.

The container 8 is equipped with nozzles having a drain 13 and an intake 14 parts and connecting the cavity of the container 8 with the sprues 7 of the covers 6. The nozzle with its drain part 13 is placed in the throat ff

the fault is attached to its end by means of a flange 15, the junction with the lid 6, and the intake part 14 is placed in the cavity of the container parallel to its bottom. The length of the drain part of the pipe is equal to the length of the neck. Such a more constructive solution provides the minimum gap between the intake part of the nozzle and the bottom, which excludes the possibility of the captivity getting into the nozzle and then into the mold.

The working volume of the tank 8 is designed for multiple castings.

The device works as follows.

In the initial position of the furnace, one of the necks, for example, the necked .11, is located vertically. Through the filling neck 9, the working cavity of the tank 8 is filled with melt to a level below the forming drain part 13 of the branch pipe of the horizontal neck 10.

At the same time, the melt through the nozzle located in the neck 11 and the sprues 7 of the lids 6 fills the working cavity of the mold 5. After the casting solidifies, the furnace 1 rotates, as a result, the throat 10 takes up a vertical position and the melt fills the specified path 4 6, mounted on the neck 10, and casting is removed from the mold 5. Thus, changing the position of the furnace 1 by turning it one way or the other, alternately setting the neck in a vertical position, the castings are continuously obtained until the need arises in the melt valley to the tank 8, after which the cycle repeats.

The presence of nozzles, their design and location prevent the ingress
