(54) COILING MACHINE

The invention relates to a foundry industry, in particular to equipment for casting under low pressure, and can also be used in installations with gravity casting. In the known chill machines and installations for pouring under low pressure, the lower part of the mold (pallet) is located between the lateral half-COIL $ 1 MI during servicing. The disadvantages of such machines are the inconvenience of maintenance (cleaning, painting the pallet, which is between the lateral half-chillies that are pre-ZOO; the need for special measures (blocking, using restrictive pins, etc.) to prevent the side halves from being closed during maintenance the inconvenience of placing sand cores on a pallet on the pallet due to the limited distance (32 O-63 O mm) between the side semicokili. In addition, the hot rod on it cannot be left on the pallet. For the purpose of expanding the technological capabilities of the machine and ease of maintenance, the proposed tuck-plate with a pallet is equipped with a vertical movement drive mounted on a rotary traverse made C-shaped and provided with guides for moving the tuck-plate with the pallet. Fig. 1 shows a chill machine, a general view; Fig. 2 is the same, side view, and Fig. 3 is a section along A-A in Fig. 2 (with the raised position of the pallet). The chill machine contains a frame 1, on which the drives 2 and 3 of the side semi-chillers are mounted. The cocoon is not shown and the swiveling traverse 4 is C-shaped. we. In the bores of the traverse, there are installed guides 5, on which the switch: o mounted a submill plate 6 s

Pozzson 7. And the upper part of the crosshead is installed hydrocylinar 8, the rod 9 of which is coupled with a drill.

The traverse is equipped with a turning mechanism 10.

In the upper part of the bed, an ejector of 11 castings is permanently installed, under which the receiving section is located.

12.

When supplying metal from the bottom under the pallet stir filling device 13 The machine works as follows. After removal of the casting, the actuators 2 and 3 are open, the pallet is in the filling position in the lower position. For maintenance (installation of sand cores, cleaning, painting), the pallet with the aid of the rod 9 rises to the level of the upper cutoff of the actuators 2 and 3. Then the pallet is lowered to the lower position, the actuators 2 and 3 are closed. Next, manually or with the help of the device 13, the metal is poured.

At the end of the crystallization of the casting, the drives 2 and 3 open, the mechanism Yu turns the traverse along with all the e elements and the casting by 180. Then

the ejector throws the casting from the pallet onto the receiving pan.

If there is an upper rod in the chill mold and there is a possibility that the casting is pinched on the pallet to forcibly leave the upper rod after pouring solidification of the casting, the hydraulic cylinder lowers the pallet through the tilting plate together with the device 13. When eton drives 2 and 3 are open, the casting remains on the upper rod.

Claims (1)

The invention of the chill machine is mainly for casting under low pressure, including a frame with side drive semi-chills fixed on it and a rotary head plate with a tilting plate on which a pallet is installed, characterized in that, in order to expand the technological capabilities of the machine and ease of maintenance, the tuck-plate with a pallet it is provided with a vertical movement actuator fixed on a rotary traverse made of a C-shaped form and equipped with guides to move the undercool Noah plates with a pallet. / /// ( one FIG. 2 AK Fig.Z
