山西大同齿轮厂铸造分厂原有两台Z2410造型机,但因震击气缸和震击活塞磨损严重,使生产无法正常进行。后又购进一台,并对这三台造型机的震实机座进行了改进,从而改善了震击气缸和活塞的磨损状况。分析认为活塞磨损的主要原因是:震实活塞上升时震击平台与震实机座之间产生一负压区,使在震击过程中从模板及砂箱上震落的部分型砂吸到平台与机座之间(见图1),并不断 Shanxi Datong Gear Factory casting factory original two Z2410 molding machine, but because of the shock cylinder and shock piston wear serious, so that production can not be normal. After the purchase of a Taiwan, and these three molding machine shock base has been improved, thereby improving the shock cylinder and piston wear conditions. Analysis shows that the main reason for the piston wear is that when the piston rises, a negative pressure zone is formed between the shock platform and the vibrating frame, so that part of the sand which falls from the template and the flask during the shock process is sucked to the platform And the base (see Figure 1), and continue
