大型压铸模的定模与动模之间的温差,会引起其热膨胀量的差异,显然要求在圆形导柱与导套之间有相当大的间隙,是不利于两半压铸模的配合和导向,也必然会影响压铸件的精度。本文陈述的矩形导向件的安置位置和方向对导向性能的影响,正是为了减少导柱和导槽两者位置的相对偏移现象,以提高大型模具导向件的导向精度。 Large die-casting mold fixed mold and moving the temperature difference between the mold will cause the difference between the amount of thermal expansion, apparently required in the circular guide column and the guide sleeve has a considerable gap between the two mold is not conducive to the cooperation and Guidance, but also will inevitably affect the accuracy of die-casting. This article describes the placement of rectangular guides and orientation of the guide performance, precisely in order to reduce the relative position of the guide post and the guideway offset phenomenon, in order to improve the guidance of large-scale mold guide precision.
