Numerical-control low-pressure casting machine

Abstract

The invention provides a numerical-control low-pressure casting machine. The numerical-control low-pressure casing machine comprises a liquid crystal touch screen, a turbo type air compressor pump, a main controller, an air valve, a U-shaped storage crucible and a high-resistance heating layer. The air valve is arranged at the bottom of the left side of a safety protective case. The main controller is installed at the top of the left side of the safety protective case. The liquid crystal touch screen is arranged at the left end of the upper surface of the safety protective case. The U-shaped storage crucible is fixed to the right end of the interior of the safety protective case through a support. The high-resistance heating layer is evenly distributed on the outer wall of the periphery of the U-shaped storage crucible. Compared with the prior art, the numerical-control low-pressure casting machine has the following beneficial effects that the main controller and the liquid crystal touch screen are arranged in cooperation so that the pressure of the numerical-control low-pressure casting machine can be controlled under a numerical-control operating system, flowing stability of molten metal is guaranteed, the flow velocity and the flow can be controlled continuously and accurately, the quantity of internal impurities is reduced, and the quality of workpieces is improved.

Description

technical field [0001] The invention is a numerically controlled low-pressure casting machine, which belongs to the field of low-pressure casting numerically controlled equipment. Background technique [0002] Low-pressure casting is a special method of filling the cavity with liquid metal under pressure to form a casting. Because the pressure used in the process is low, it is called a low-pressure casting machine. This can effectively reduce product costs. High-quality castings are obtained, but the current low-pressure casting method still has some shortcomings. [0003] First of all, the liquid metal used in casting is generally stored in a crucible, which uses the good heat resistance of the crucible, but it cannot be stored for a long time. After its natural cooling makes the liquid metal too viscous, the casting cannot be completed only by pressurization. , resulting in a large waste of resources; secondly, in addition to the crucible, other materials used have poor h...

[0002] Low-pressure casting is a special method of filling the cavity with liquid metal under pressure to form a casting. Because the pressure used in the process is low, it is called a low-pressure casting machine. This can effectively reduce product costs. High-quality castings are obtained, but the low-pressure casting methods used today still have some deficiencies

[0003] First of all, the liquid metal used in casting is generally stored in a crucible, which uses the good heat resistance of the crucible, but it cannot be stored for a long time. After its natural cooling makes the liquid metal too viscous, the casting cannot be completed only by pressurization. , resulting in a large waste of resources; secondly, in addition to the crucible, other materials used have poor heat resistance, and dangerous accidents such as explosions are prone to occur when air is compressed in a high-temperature environment, which is not conducive to the development of the low-pressure casting industry; finally, pressurization is completed. In the process of casting castings, the length of pressurization time depends entirely on the experience of the staff, and cannot be clearly and intuitively observed. This results in uneven quality of castings due to different experience and technology, resulting in huge economic losses, and contains great potential danger
