Title: Powder vibration absorber
Inventor: TATARA YOICHI
IPC: F16F9/30
Filed: 1986-08-07
Abstract: PURPOSE:To perform the braking and vibration absorption of a piston shaft linearly or rotatively moving by utilizing the phenomenon that while such object as a piston or the like moves in powder whose mobility is restricted by a cylinder or the like, the kinetic energy is absorbed. CONSTITUTION:A cylinder 2 is crammed with powder 1 which a piston 3 is placed therein. For the powder used, dried silica sand is suitable, and the specifying of the shape, quality of material, liquid content ratio, and particle diameter is not required. In case of silica sand, a particle diameter in the range of from several meshes to several hundreds meshes is suitable. When a piston rod 4 moves linearly and reciprocatively, the piston 3 directly connected to the piston rod 4 is subject to pressure drag. And the frictional force (mainly frictional drag) generated in the flow motion of the powder 1 in the space between the piston 3 and a cylinder wall is given to the piston rod 4. Therefore, since the kinetic energy of the piston rod 4 is absorbed, the effects of the braking and absorption of the vibration of the rod 4 is remarkable.

Abstract: PURPOSE:To reduce a setting time in the stage of changing an injection speed and to improve the quality of a product by changing adequately the flow rate of the liquid to be supplied to an injection cylinder and the flow rate of the liquid to be discharged therefrom in first half and second half processes according to the change rate of the speed of an injection plunger. CONSTITUTION:A molten metal is not thoroughly filled in an injection sleeve if a set change rate of speed is small, that is, in the case of changing the speed to a low or middle speed or in a stage of injection at a speed except a high speed. If the feeding speed of the injection plunger waves on account of such imperfect filling, intrusion of gas is liable to arise and therefore the injection is so operated that the operating process in approximately the first half part Y has a gradually accelerating characteristic and that the operating process in approximately the second half part X has a gradually accelerating and decelerating characteristic. The molten metal is thoroughly filled in the injection speed in the case of changing the speed to a middle high or high speed and therefore approximately the first half part is risen linearly to change sharply the flow rate without operating said part in the accelerating characteristic so that the gradually accelerating and decelerating characteristic is provided only in the operating stage for approximately the second half process.
