我厂45°分型面圆截面胶圈模具的生产始终存在较大技术难题。主要问题是上下模合模后型腔错位,飞边太厚,截面不圆,型腔表面粗糙度值大等,致使压出的胶圈不合格。现在,我们应用先进的数控技术,在数控车床上加工合模锥面,利用坐标数据,通过精确的对刀 I plant 45 ° sub-surface round-section apron mold production there is always a big technical problems. The main problem is the upper and lower mold cavity after the mold dislocation, the flash is too thick, cross-section is not round, the cavity surface roughness value, resulting in out of the apron unqualified. Now, we use advanced numerical control technology, CNC mold lathe machining conical surface, the use of coordinate data, through the precise knife
