Abstract

The invention relates to foundry and can be used in the manufacture of large parts in the form of bodies of rotation. The purpose of the invention is to increase the reliability and improve the operating conditions of the machine. The machine is equipped with a ventilation pipe, installed on the end wall of the casing, and two pillars 11. The hinged cover-casing 7 is double-folded. The tilting mechanism of each casing cover flap is made in the form of a pneumatic cylinder 9 and two levers 10. In the closed position of the flaps, the size of the lever 10 is chosen so that they are in one line, excluding their arbitrary tilting of the flaps during operation. On the cover-cover-casing 7 spring-loaded pressure rollers 8 are installed, which allow the mold 4 to be reliably oriented in the roller supports 2. 2 Il. (L

The invention relates to foundry and can be used in the manufacture of large pieces of abarted parts in the form of bodies of rotation, mainly bushings of large diameters with a wide defined range of wall thicknesses and lengths} 1.

The purpose of the invention is to increase the reliability and improve the operating conditions of the small.

On fi1. 1 shows the proposed machine without a hinged cover of the casing, general view; figure 2 - the proposed machine with a folding double cover of the casing, the view from the end.

For additional fixation of the cusps of the cover-casing 7, an air fixer 15 is provided.

The centrifugal casting machine for casting operates as follows.

The mold 4 is installed on the roller supports 2 and 3. In this case, the i-pi: i-ki-casing stiorkha 7 are set apart. At the installation of the mold 4, the flaps are turned to the nojHioro stroke of the cylinder 9. The levers 10, turning, are set in one line, creating a dead position. The injected device 14 is applied to the mold and the chute enters the mold for the length set by the technology. The drive 13 is turned on and the rotation of the set-up is triggered (dips L (. 1 1: circulating speed, noc: i.e., liquid metal is fed through the chute of the devices 14). The emitted harmful gases are sucked out through the nozzle.
