专利号瑞士635255 申请日期 1978年7月19日公布日期 1983年3月31日申请者 Zimmermann Rene＇本专利适用于卧式冷室压铸机的结构,压射活塞头不象一般压铸机那样与压射活塞杆采用刚性联接,而是在压射行程中可以沿轴向移动。活塞杆不象现有压铸机上的那样采用整体结构,而在里边有一个组合件,它在向压型工作腔输送金属液的过程中消除动力冲击。压射杆3上拧有套4,作为活塞头7滑动的支承。在压射杆和套4的里面有孔,用于不燃工作液或矿物油的流通,矿物油按箭头方向沿管12的槽11流动,然后矿物油沿套25的槽14 Patent No. Switzerland 635255 Date of Application July 19, 1978 Date of Application March 31, 1983 Applicant Zimmermann Rene ’This patent applies to the construction of horizontal cold chamber die casting machines that are not as pressurized as conventional die casting machines Shot piston rod rigid connection, but in the injection stroke can be moved along the axial direction. Piston rod unlike the existing die-casting machine as a whole with a structure, which has an assembly inside, it is in the metal working fluid pressure chamber to eliminate the impact of power. The plunger 3 is screwed onto the plunger 3 as a sliding support for the piston head 7. There is a hole in the plunger and sleeve 4 for the flow of an incombustible working fluid or mineral oil that flows in the direction of the arrow along the groove 11 of the tube 12 and then the mineral oil flows along the groove 14 of the sleeve 25
