Abstract: The present invention is intended to provide an injection molding die that improves the strength of adhesion between an insert and a plastic in an insert molded article while suppressing fluctuations in the strength of adhesion. An injection molding die is used to manufacture an insert molded article by placing an insert 12 with a thermoset resin adhesive in the molding die and injecting a molten plastic material P from a gate G into a cavity C. The gate G is arranged at a position separated by 0.2 mm or more in an out-of-plane direction from a surface A1 of the adhesive applied to the joining surface of the insert 12. During injection molding, the wall surface shear stress generated on the adhesive applied to the joining surface of the insert 12 relative to the plastic near the gate G becomes small. The adhesive is not swept away by the high-pressure molten plastic material P without having to bring the adhesive applied to the joining surface A of the insert 12 into the semi-cured state.

Abstract: In a rotary impact tool according to an aspect of the present disclosure, an impact mechanism rotates an output shaft by a rotational force of a motor and, when a torque equal to or greater than a given value is externally applied to the output shaft in a direction opposite a rotational direction of the output shaft, the impact mechanism intermittently applies an impact force as a momentary torque to the output shaft in the rotational direction of the output shaft. A protection unit stops the motor or reduces a rotational speed of the motor on condition that an abnormal impact detection unit detects the abnormal impact. A control unit controls activation of the protection unit differently when the rotational direction of the motor is set to a reverse rotational direction in comparison with when the rotational direction of the motor is set to a forward rotational direction.
