Embodiment Construction
[0013] refer to figure 1 , a screw for injection molding machine of the present invention, comprising a body 1, and a feeding groove 2 spirally surrounding the surface of the body 1, the diameter of the body 1 increases from the beginning to the end, and the depth of the feeding groove 2 is It gradually increases from the beginning to the end, and a plurality of grooves 3 with square openings are arranged at intervals on the feeding chute 2. The surfaces of the body 1 and the feeding chute 2 are covered with a ceramic coating. The screw of the injection molding machine of the present invention is convenient for melting plastics. Smooth flow to the discharge end, less resistance, less stagnation, high production efficiency; uniform mixing, less air bubbles, high plasticization quality; the screw itself has strong corrosion resistance, wear resistance, high temperature resistance, and is more durable.
[0014] In this embodiment, preferably, the groove 3 has a circular or ellipt...
