Disclosed is a squeeze for a screen printer. The present invention provides a squeeze for a screen printer, which coats a printed circuit board with an adhesive paste while moving parallel over a metal mask on the printed circuit board, the printed circuit board being open through an opening of the metal mask, the squeeze including a solvent storage unit for storing solvents; and solvent discharging holes for discharging the solvents, stored in the solvent storage unit, to an adhesive paste. Accordingly, the squeeze for a screen printer of the present invention may be useful to prevent a dog ear phenomenon, namely that an adhesive paste layer is asymmetrically formed in an indented manner, by controlling a viscosity of an adhesive paste by discharging a solvent onto an adhesive paste layer that comes in contact with the squeeze when the adhesive paste layer is formed in the printed circuit board.

A piston head of a hydraulic injection molding machine is screwed with a tie rod inside a hydraulic cylinder of the hydraulic injection molding machine. The piston head has a second screw formed in an inner circumference of a hollow of the piston head and engaged with a first screw formed in an outer circumference of the tie rod. An insert groove having a predetermined shape is formed in the inner circumference of the piston head in front of the second screw.

A mold adjustment device of an injection molding machine is required for movement of a rear template that moves depending on a size of a mold in a toggle clamp of the injection molding machine. At this time, a spherical bearing and/or a bushing is attached to an outer circumference of a nut of a tie bar gear that rotates along a tie bar and a tie bar screw enduring a clamping force of the toggle clamp so as to be contacted with the rear template. This mold adjustment device clears up any factor generating vibration or noise during the injection molding, thereby remarkably decreasing stoppage generated during the mold adjustment process and also relatively reducing vibration and noise.
