我厂压铸件生产特点是项目少,批量小。模具结构大部分是由型、芯活块组成,最长型芯为100毫米,故抽芯机构大多采用液压拉杆。由于生产不连续,机械操纵部分有时锈蚀失灵,加之操作不熟练,型芯经常造成断裂。有些模具因使用年久,受金属液冲击磨损粘铝现 I die casting factory production is characterized by small projects, small quantities. Most of the mold structure is composed of type, core live block, the longest core is 100 mm, so the core pulling mechanism are mostly hydraulic rod. Due to discontinuity of production, sometimes the mechanical control part of the corrosion failure, coupled with unskilled operation, the core is often caused by fracture. Some die due to the use of a long time, by the liquid metal impact wear aluminum stick now
