在仪器仪表压铸中,有时会遇到小斜度、无斜度、小直径的深孔和薄壁T形槽以及局部无飞边等特殊要求的零件,这就给模具设计制造及压铸工艺带来很大困难,甚至只能做出试样而无法大量生产。为此,我们与使用单位协商,对压铸件的设计和模具结构、镶拼方法等方面作了必要的改进,并采取了 In the instrument die-casting, and sometimes will encounter a small slope, non-gradient, small diameter deep holes and thin T-slot and local without flash and other special requirements of the parts, which give the mold design and manufacturing and die-casting process with It is very difficult to make samples and can not be mass-produced. To this end, we consulted with the use of units, the die-casting design and mold structure, inlaid spellings, etc. made the necessary improvements, and adopted
