Main structure of gravity casting machine

   Gravity Casting Machine is a casting equipment for making casting products. It can be used to produce products in many industries, such as medical equipment, tableware, auto parts, electrical accessories, etc. We know that the principle of gravity Casting Machine is to produce castings under the action of gravity, but many people do not know the main structure of gravity casting machine. Let me take you through it below.

   1. Basic structure of gravity casting machine

 

Gravity casting machine mainly consists of the following parts: mold system, pouring system, cooling system and control system.

 

1. Mold system

 

The mold system is one of the core parts of gravity casting machine. It is usually composed of sand mold or metal mold to contain molten metal and form the required casting shape. Sand mold is mainly made of materials such as quartz sand, binder and additives, and has good heat resistance and air permeability. Metal mold is made of materials such as steel or aluminum alloy, which is suitable for mass production and high precision castings. The design and manufacture of molds need to take into account factors such as the size, shape, wall thickness of the casting to ensure the quality and production efficiency of the casting.

 

2. Pouring system

 

The pouring system includes sprue, runner and ingate. The molten metal enters the runner through the sprue and then flows into the mold cavity through the ingate. The reasonable design of the pouring system is crucial to control the metal flow rate and avoid problems such as slag inclusion and pores. For example, a reasonable pouring system can reduce the porosity defects inside the casting and improve the density and mechanical properties of the casting.

 

3. Cooling system

 

The function of the cooling system is to provide uniform cooling conditions during the solidification of the casting to avoid cracks and deformation caused by uneven cooling rates. Common cooling methods include water cooling, air cooling and natural cooling. For large castings, special cooling channels may also be required to accelerate the cooling process. In addition, some high-end gravity casting machines are also equipped with temperature monitoring and control devices to achieve precise control of the cooling process of the casting.

 

4. Control system

 

The control system is the "brain" of the gravity casting machine and is responsible for coordinating the work of various systems. It includes electrical control systems, hydraulic control systems and computer-aided control systems. The electrical control system is responsible for controlling electrical components such as motors and solenoid valves; the hydraulic control system is used to drive actuators such as hydraulic cylinders and hydraulic motors; the computer-aided control system can monitor and optimize the entire casting process. Advanced control systems can significantly improve production efficiency and casting quality.
