The fully hard cone double machine barrel screw rod of money spiral shell rib structure diversification.
Invention content
The purpose of this utility model is to provide fully hard cone double machine barrel screw rod.
Problem to be solved in the utility model is the spiral shell rib knot in the screw body of the fully hard cone double machine barrel screw rod of the prior art
The all excessively single problem of structure.
For realization the purpose of this utility model, the technical solution adopted in the utility model is：
Fully hard cone double machine barrel screw rod, including screw head, third screw body, stirring ball, third agitation beads, the second agitation beads,
4th screw body, the second screw body, the second spiral shell rib, perpendicular rib, the first agitation beads, the first screw body and the first spiral shell rib, described first
The first spiral shell rib is equipped with outside screw body from top to bottom, is the second screw body above the first screw body, the second screw body upper end from upper and
The second spiral shell rib is had, the second screw body lower end surrounding is respectively provided with perpendicular rib, and multiple first agitation beads, the second spiral shell are equipped on perpendicular rib
It is third screw body above the body of rod, third screw body each side installs the 4th screw body, the 4th screw body tail portion installation the
Two agitation beads, third screw body top are equipped with screw head, and multiple third agitation beads are installed outside screw head, are to stir at the top of screw head
Ball.
The diameter of the third screw body is less than the diameter of the second screw body.
The first screw body lower end diameter is more than the first screw body upper end diameter.
The stirring ball is hemispherical dome structure.
The utility model has the advantages that：Third agitation beads play the role of stirring the material of barrel front end so that injection molding
Effect is good, will not make to generate bubble in product；Third screw body and the 4th screw body can play the role of material stirring and tearing,
So that melting effect is good, the bubble in material can be removed, makes do not have bubble in the product of discharging；Perpendicular rib and the first agitation beads are mixed
The bubble in material can be removed in refining, which has diversified spiral shell rib structure.
