Title:
INJECTION PRESSURE MEASUREMENT DEVICE, INJECTION PRESSURE MEASUREMENT METHOD AND MOLDING SYSTEM
Document Type and Number:
Japanese Patent JP2023054402
Kind Code:
A
Abstract:
To provide a device capable of correctly measuring injection pressure without adding a manual special operation.SOLUTION: An injection pressure measurement device comprises: an extrusion pin (21) facing molds (14, 15) and extruding a molded body from the molds (14, 15); a servo motor (35) as a driving source of the extrusion pin (21); and a controller (5) for controlling the driving of the servo motor (35). The controller (5) obtains the injection pressure (IP) of the molten raw material of the molded body charged to a cavity (16) of the molds based on the torque of the servo motor (35) produced by the pressing of the extrusion pin (21) by the molten raw material.SELECTED DRAWING: Figure 1
