Abstract

PURPOSE:To let a plunger having no ring make sliding contact reciprocatively with a sleeve and improve the use times of the plungers by fixing the plunger head of hardness higher than the base body of the plunger to the end of the base body and inserting the same into the sleeve. CONSTITUTION:The fitting recess 3a of a plunger head 3 is fitted onto the circular cylindrical part 2C of plunger base body 2. Next, a bolt 4 is inserted into the bolt hole 3b of the plunger head 3 by way of a washer 5 and is screwed into the screw hole of the base metal 2 to fix the plunger head 3 to the base body 2. Next, the outside peripheral surface 3' of the plunger head 3 is slide-contacted with the inside peripheral surface 1a of the sleeve 1 and the plunger A is reciprocatively inserted therein, whereby the molten metal pressing machine is obtained.
