总结了活塞铸造生产中铸模的有关问题:新产品活塞铸模投产前的浇注调试、铸件检验;活塞铸模在正式投产后的维护、保管和修理;活塞铸模的报废处理和更新。经过几年的生产实践检验证实:铸模调试工作极为重要,是铸模设计、制造的验证,是顺利投产的保证;而投产后的铸模,只要善于维修就能延长铸模的使用寿命,一副外模可浇20000～25000只活塞;一付芯模可浇7000～10000只活塞;铸模的合理报废、及时更新、广泛互换、有利于安排和组织生产。
Summarized the casting mold in the piston casting related issues: the new product before the start of the casting mold casting commissioning, casting inspection; Piston mold in the official put into operation after the maintenance, storage and repair; Piston mold scrapped and updated. After several years of production practice test confirmed: mold debugging is extremely important, is the mold design, manufacturing verification is the guarantee of smooth operation; and put into operation after the mold, as long as the maintenance can extend the life of the mold, an external module Pour 20000 ~ 25000 Pistons; a pair of mandrel can be cast 7000 ~ 10000 Pistons; mold scrapped properly updated and widely interchangeable, help to arrange and organize production.
