Shanghai Daoqin Plastics Co., Ltd.

         in front fine research analysis 总装图. parts 图, understanding parts function, features and its technology requirements,确定 assembly 基准. through assembly, most rear comprehensive to product quality indicators, mold as degree and use process in technology requirements.

         assembly 基准

        (1)以 plastics in main/primary as parts type 芯, type and block and other as is assembly parts, mold its it parts has assembly parts 进行配 made and assembly.

        (2)以导柱导 sleeve/set or mold sheet/plate 侧基面 is assembly 基准面进行修整 and assembly.

         mold assembly degree

        (1)各零,部 parts versus 互僮精 degree,如距离 dimensions degree,同轴 degree,平 and other degree,垂直 degree and other.

        (2) versus for 运动精 degree,如传动精 degree 直线运动 and 回转运动精 degree and other.

        (3)配 combined degree and 接触精 degree,如配 combined 间隙, amount 接触状况 and other.

        (4) plastics formed parts thick large small. new made mold 时, formed parts thick 应偏于 dimensions lower 限.

        修配原则

        (1)修配 demolding degree,原则 upper type ensure large dimensions in made parts dimensions scope/range inner type ensure small dimensions in made parts dimensions scope/range inner.

        (2)角隅处圆角 semi 径, type 腔应偏 small, type 芯应偏 large.

        (3)当 mold has water separation type also has separation type 面时修 positive make separation type 面接触时 water separation type 面稍稍留 has 间隙. value 视>0.01mm; small type mold coating upper rear versus 互接触即 can; large type mold 间隙约 is 0.02mm left right.

        (4) for/regarding use clamping mold,斜面密 combined rear, separation type 面处应留 has 0.02-0.03mm 间隙.

        (5)修配 surface and 直线连接 need slip, surface 不允许 has 凹痕,锉削纹路应 and mold opening direction 一致.
