我厂铸造二车间是以生产球铁件为主的小型铸造车间,年产铸件1000t。自1985年我厂与上海某厂签订了油马达铸件的生产合同后,由于铸件质量要求较高,如铸件外型尺寸公差要求为±1.0mm,采用手工造型方法很难达到铸件的质量要求。另外由于手工造型效率低,也满足不了批量生产的要求。于是我们先后自制了8台简易漏模机,经几年来的批量生产验证,铸件外观质量和尺寸精度明显提高,生产效率也提高了1～2倍。简易漏模机的整体结构见图,它主要由气
I plant casting two workshops is mainly the production of ductile iron small casting workshop, with an annual output of castings 1000t. Since 1985, the factory and Shanghai plant signed a production contract of the oil motor castings, due to the higher casting quality requirements, such as castings dimensional tolerance requirements of ± 1.0mm, the use of manual molding method is difficult to achieve the quality requirements of the casting. In addition due to the low efficiency of manual modeling, but also can not meet the requirements of mass production. Therefore, we have homemade 8 simple leak-casting machine, after several years of mass production verification, castings appearance quality and dimensional accuracy significantly improved production efficiency has also increased by 1 to 2 times. The overall structure of a simple leak-proof machine shown in the figure, it is mainly by the gas
