Title:
INJECTION DEVICE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/163486
Kind Code:
A1
Abstract:
In an injection device (10) according to an embodiment, each of a plurality of outer peripheral protrusions (50) of a screw (12) is formed with an outer peripheral protrusion inclined surface (50S), and each of a plurality of inner peripheral protrusions (60) of a through-hole (14H) of a bush (14) is formed with an inner peripheral protrusion inclined surface (60S). The injection device (10) advances the bush (14) until a linear-motion torque exceeds a linear-motion torque threshold, and, if a rotation torque exceeds a rotation torque threshold before the linear-motion torque exceeds the linear-motion torque threshold, ends control processing when the linear-motion torque exceeds the linear-motion torque threshold.
