Abstract
PURPOSE: To prevent wear and damage of a clutch plate by controlling an upper mold supporting oil pressure in an overload safety device to the pressure reducing direction in synchronization with the pressure application and holding, enabling the pressure applying and holding power to be established, and performing the pressure applying and holding at suitable low pressure at all times.
CONSTITUTION: A rotary motion is transformed into up and down movement of a slide. The maximum clamping power is obtained by the upper and lower molds at the lower dead point of the slide, and melted resin is formed. In the apparatus, is provided an oil discharge control device 12 for lower chambers A, A' and B of cylinders between hydraulic feed path 9 for the hydraulic overload safety device and oil recovery tank. As a suitable example, a solenolid valve is used. When the maximum clamping power is given and the pressure is maintained, a solenoid SL is actuated and a normally closed valve is opened. Then the oil is discharged, the oil pressure at the lower chambers A, A' and B of the cylinders is reduced in response to the amount of the discharged oil.
