车板支架的作用,是固定车板轴线中心度的,使轴线不致向任何方向偏斜。在车制时,只需保持车板轴线与型腔分型面在车板尺寸方向垂直(见图1所标垂直度),便能确保型腔尺寸的精确。因此,只要在埋设天心时注意其深度,即砂箱端面至天心表面的深度,这个深度应等于车板的有效高度(见图1中的H)。这样,分型面与车板的轴线自然就垂直了。由于分 The role of the car plate support is to fix the centerline of the car axis so that the axis does not deflect in any direction. In the car, just keep the car axis and cavity sub-surface perpendicular to the direction of the size of the car (see Figure 1 marked vertical), will be able to ensure accurate cavity size. Therefore, as long as the depth is buried in the heavenly heart, that is, the depth from the face of the flask to the surface of the heart, the depth should be equal to the effective height of the car (see Figure 1, H). In this way, the parting plane and the axis of the car naturally vertical. Due to points
