Aluminum die casting's die casting process

Xinxin Die-casting Factory in Pinghu County, Zhejiang Province specializes in the production of aluminum alloy die-casting, zinc alloy die-casting and other non-ferrous metal die-casting products. With various mold manufacturing equipment and product surface brightening treatment, we are committed to producing various molds. Let's introduce aluminum die casting.

Actual smelting operation: As described earlier, the whole process of pouring is basically the same as general forging, and the specific steps are related to the smelting of aluminum alloy profiles and the forging of scrap aluminum for remelting.

According to the basic theory of aluminum die-casting aluminum die-casting, the standard ingot die is continuously forged to meet the common forging methods of aluminum electrolysis plants. It is applicable to the casting production and manufacturing of simple contour specifications and appearance design, the net weight is not large, and non-immediate production and processing. Die-casting and forging various aluminum and aluminum alloy profiles for remelting aluminum scrap. There is a professional casting machine for this type of forging.

The horizontal rotary casting method is a forging method with a high degree of mechanical automation in the block iron mold casting method. The aluminum die-casting and forging process is very simple. Because the aluminum alloy ingots for remelting are produced, the shortcomings of the casting surface and the internal crystal structure regulations are relatively not strict. However, at the current stage, customers in the sales market For example, A356.2 forged aluminum alloy ingots still have requirements for the level of pinholes. The requirements of translational continuous forging for processing technology are mainly pouring temperature, pouring rate and water cooling heat dissipation control.

1. Pouring temperature Aluminum and aluminum alloy profile ingots for heavy cultivation are different due to different types of aluminum alloys, so the pouring temperature is also different. In general, the pouring temperature of ordinary aluminum and deformed aluminum alloy profiles is in the range of 30-80 degrees above the temperature of the aluminum alloy crystal. Aluminum alloy casting is within 30-50 degrees above the crystal temperature.

2. Casting rate Translational continuous forging of ingot molds are all fixed-shaped casting machines. Casting machines of different models and specifications have different forging rates. The forging rate is adjustable. The forging rate is indicated by the traveling rate of the mold. But in order to visualize it, forging workers generally measure the forging rate by casting several ingots per minute. It should be emphasized that the forging rate does not need to be adjusted too fast, otherwise, the aluminum die-casting machine will vibrate greatly, and the casting will cause serious wave patterns and surface air oxidation.

3. Refrigeration operation: The refrigeration method of the translational ingot mold rotary casting machine is divided into two types: one is the immersion type forced water cooler at the bottom of the mold, the key operation is that the water seepage temperature is below 40 degrees and the distance between the floor heating pipes is below 60 degrees. . The other is the cooling method of casting. However, in order to ensure the normal operation of the casting machine, it is necessary to reduce the temperature of the mold. The tap water is used for self-injection cooling before or after the mold is cast, which can reduce the temperature of the mold, which prevents aluminum die casting. The common failures of machinery and equipment that will occur in the high temperature operation of the casting machine are also beneficial to the stability of the casting mold and the processing technology standards. The sprinkling temperature of this type of refrigeration method is generally specified below 40 degrees.
