铝合金压铸件出现拉伤的原因?

来源:http://www.jnhjgs.cn     发布时间:2020-11-12 17:30:46    点击:

随着当今社会的不断发展,铝合金压铸件的使用已变得非常普遍。 产品用于石油,工业和矿物工业。 在我们的日常生活中,这种铝合金压铸件主要用于汽车,因此许多人会单独列出汽车压铸件。
With the continuous development of today's society, the use of aluminum alloy die castings has become very common. The products are used in petroleum, industrial and mineral industries. In our daily life, this kind of aluminum alloy die casting is mainly used in automobile, so many people will list automobile die casting parts separately.
铝合金压铸件的痕迹主要是由于铸件的线形表面沿开模方向造成的。 如果走线具有一定深度,则在严重情况下可能会使整个表面变形。 铝合金压铸件的模具表面和金属液体粘在一起,这将导致铸件表面材料不足。
The trace of aluminum alloy die casting is mainly caused by the linear surface along the opening direction. If the routing has a certain depth, it may deform the entire surface in severe cases. The die surface of aluminum alloy die casting is adhered to the liquid metal, which will lead to insufficient surface material.
铝合金压铸件缺陷的主要原因是在脱模时模腔表面损坏或倾角过小,在脱模过程中发生平衡,或者因这种情况而导致模具松动。
The main reason for the defects of aluminum alloy die castings is that the surface of die cavity is damaged or the inclination angle is too small during the demoulding process, or the die looses due to this situation.

铝合金压铸件的处理是及时修复模具表面的损伤并修整模具的倾斜度,从而可以很好地提高模具表面的光滑度,并在顶出时可以平衡顶出力。 引脚已调整。
The treatment of aluminum alloy die casting is to repair the damage of die surface and repair the inclination of die in time, so as to improve the smoothness of die surface and balance the jacking force during ejection. The pins have been adjusted.
铝合金压铸件使用时需要进行良好的控制,以使模具的温度达到200度。 在控制时,需要准确地控制温度,因此需要用于铝合金压铸的专用模具温度机。
Aluminum alloy die castings need to be well controlled to make the temperature of the die reach 200 ℃. In the process of control, it is necessary to control the temperature accurately, so a special mould temperature machine for aluminum alloy die casting is needed.
使用一段时间后,需要及时更换铝合金压铸件的脱模剂,然后合理调整铝合金的铁含量和冷却时间,并制成成品的内浇口。 需要及时修改。
After using for a period of time, it is necessary to change the release agent of aluminum alloy die casting in time, and then reasonably adjust the iron content and cooling time of aluminum alloy, and make the inner gate of the finished product. It needs to be modified in time.
