[0055] When feeding, the device is first preheated by the electric heating wire 106, and then the servo motor 103 is started to drive the feed rod 108 and the spiral blade 107 to rotate inside the feeding barrel 104.

The servo motor 103 drives the spiral blade 107 to reciprocate inside the feeding barrel 104 through the feed rod 108, so that the raw materials can be squeezed and transported;

[0056] The concave groove 209 inside the rotating ball 208 corresponds to the position of the discharge groove 203. When injection molding is required, the hydraulic cylinder 102 pushes the feed rod 108 to move toward the rotating ball 208, thereby squeezing the liquid, and entering the inside of the feed groove 205 through the through groove 210 and the discharge groove 203, and entering the inside of the through hole 403 through the feed groove 205, and entering the inside of the mold assembly 005 through the through hole 403 and the second connecting block 502, and performing injection molding and shaping;

After the discharge is completed, the hydraulic cylinder 102 drives the feed rod 108 to retract and starts the precision motor 206 at the same time. The precision motor 206 drives the rotating ball 208 to rotate 90 degrees through the rotating rod 207, thereby blocking the through groove 210 to prevent material leakage. Since the concave groove 209 is set to be concave, when the concave groove 209 turns to the side of the discharge groove 203, due to the setting of the protrusion 211, the material inside the feed barrel 104 can be prevented from flowing out through the concave groove 209, and the concave groove 209 can temporarily store the liquid material inside the discharge groove 203, and the slight negative pressure can retract the material inside the feed groove 205 to prevent material leakage.
