(3) 成形件装配和配合关于塑件的配合规定,一般嵌入件取负公差,相对件则取此公差。虽然明确了这种情况的间隙,但由于重视制件的功能和外观,实际的模具的制造精度很高,成形条件的离散幅度很小。如前所述,对成形品的尺寸尽量留有余地,因树脂特性的收缩可能出现配合太松,也可能放不进去。 (3) Forming and fitting of forming parts Regarding the cooperation regulations of plastic parts, the general inlay shall take negative tolerance and the opposite part shall take this tolerance. Although this situation is clear the gap, but due to the function and appearance of the parts, the actual mold manufacturing precision is high, forming the discrete size is very small. As mentioned above, the size of the molded product should be left as much as possible, because of the shrinkage of the resin characteristics, it may be too loose or too loose.
