Title: Hydraulic cylinder with built-in valve for positioning control
Inventor: OSHIE NAOMASA
IPC: F15B15/24
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To perform positioning of a cylinder with a built-in valve for positioning control with high precision, to improve durability of a seal and a bearing, and to reduce size. SOLUTION: A nut 2 is attached to the piston rod 1 of a hydraulic cylinder, a screw stem 3 engaged with the nut 2 is supported by a bearing 4 and fixed at an outer rotor 5. A control motor 24 is joined with an inner rotor 6 making slide contact with the outer rotor 5. Since the ends on both sides of the screw stem 3, the bearing 4, and the outer rotor 5 are always connected to a pressure chamber 9 on the cylinder press side and pressures are the same as each other and a load in one direction by a pressure is not exerted on the bearing 4, feedback of the position of the piston rod 1 is transmitted to the outer rotor 5 with high precision. Thereby, by positioning the control motor 24, the piston rod 1 is positioned with high precision.

Abstract: PURPOSE:To prevent the stagnation of a resin by providing a molten resin passage and the valve pin opening and closing the gate provided to the leading end thereof to the chip constituting a hot runner and differentiating the positions of the resin passage and the valve pin to allow the resin passage and the valve pin to cross. CONSTITUTION:A chip 1 is fitted to a fixed retaining mold 6 and a receiving plate 17 and a molten resin passage 2 is bored in the chip 1 so as to pierce the chip longitudinally. The molten resin passage 2 is formed so as to be shifted from the center of the chip 1 and the gate 4 at the leading end of the passage 2 is allowed to communicate with a cavity 20 and the base end of the passage 2 is allowed to communicate with the passage of a manifold 9. A valve pin 3 pierces the center of the chip 1 and the gate 4 is opened and closed by the tip of the pin 3. Therefore, the valve pin 3 is not positioned within the resin passage 2 and the valve pin 3 is inserted obliquely with respect to the center of the chip 1 so as to be allowed to cross the gate 4. By this constitution, the valve pin 3 is driven so as not to pass through the resin passage 2 and the stagnation of the resin passing through the resin passage 2 is prevented.
