Gooseneck operation device of full-servo multi-axis die-casting machine

A gooseneck operation device of a full-servo multi-axis die-casting machine, comprising:

• a gooseneck operation device body, which comprises a servomotor, a first transmission arm, a second transmission arm, and an injection unit, wherein the servomotor comprises a speed reduction mechanism;
• the first transmission arm has an end that comprises a spindle hole formed therein;
• the speed reduction mechanism is mounted, in an eccentric manner, to the spindle hole;
• the second transmission arm comprises a rotatable joint section and a transmission section;
• the rotatable joint section and the transmission section form therebetween a predetermined included angle;
• the rotatable joint section is rotatably mounted to an opposite end of the first transmission arm;
• the transmission section is provided with at least two bifurcation sections;
• the injection unit is provided with an inlet port and an outlet port respectively formed in a bottom surface and a front end thereof;
• and a projection section projects sideways from each of two opposite sides of the outlet port and the at least two bifurcation sections are respectively coupled to the projection sections, whereby when the servomotor is in operation, the first transmission arm and the second transmission arm are driven to cause the transmission section to rotate such that the at least two bifurcation sections are driven to oscillate frontwards and rearwards with rotation of the transmission section thereby driving the injection unit to operate.
