Vacuum pressurization balancing device of centrifugal casting machine and method thereof

Abstract

The invention discloses a vacuum pressurization balancing device of a centrifugal casting machine and a method thereof, and belongs to the technical field of centrifugal casting machines. The vacuum pressurization balancing device comprises a machine body, a centrifugal casting inner cylinder is arranged in the machine body, a press-fit cylinder cover is arranged at a cylinder opening in the upper portion of the centrifugal casting inner cylinder, and one end of the cylinder cover is fixed to the side end of the machine body through a coupling rod; and a temperature measurement monitoring device is arranged above the cylinder cover. According to the vacuum pressurization balancing device of the centrifugal casting machine and the method thereof, the sealing performance of the whole device after being sealed is effectively improved, the situation that the casting result is poor due to leakage is avoided, it is guaranteed that the internal temperature is always controlled within the set temperature, the temperature control accuracy is improved, the casting accuracy is improved, and the finished product quality is guaranteed; the pressure of the connecting end face is shared, the situation that the air pressure of a local connector is too high, and consequently the connector is damaged is prevented, the use stability of the connector is improved, internal air pressure balance can be effectively guaranteed, conversion can be conducted according to needs, and use convenience is improved.

Description

technical field [0001] The invention relates to the technical field of centrifugal casting machines, in particular to a vacuum pressure balancing device and a method for centrifugal casting machines. Background technique [0002] A casting method in which liquid metal is poured into a rotating mold, filled and solidified into a casting under the action of centrifugal force. The machine used for centrifugal casting is called centrifugal casting machine. According to the direction of the rotation axis of the casting mold, the centrifugal casting machine is divided into three types: horizontal vertical and inclined. The casting mold used in centrifugal casting can be non-metallic, metal or A mold coated with a paint layer or a resin sand layer in a metal mold. [0003] 1. The existing centrifugal casting machine vacuumizes the interior during the casting process. During the vacuum process, the internal pressure will be high.

Problems solved by technology

[0003] 1. The existing centrifugal casting machine vacuumizes the interior during the casting process. During the vacuum process, the internal pressure will be high. In the case of different internal and external pressures, the internal pressure will be unbalanced, resulting in excessive pressure at the interface. ,Affect;

[0004] 2. Secondly, the control of the existing centrifugal casting machine is troublesome, and it is impossible to monitor the internal temperature, air pressure and vacuum in real time, resulting in low practicability
