Refine function, make the temperature of melt uniform, the distribution of color of product is uniform, thus would generally screw rod one batch mixing of tip designs
Head realizes this function；At present, the batch mixing head of screw in injection molding machine mainly has two kinds, pin type batch mixing head and barrier type batch mixing
There is easy buildup in head, pin type batch mixing head, the shortcoming of self-cleaning ability difference, and the shortcoming of barrier type batch mixing head is to produce height to cut
Cut, be not suitable for temperature-sensitive material, therefore this is urgent problem.
The content of the invention
The purpose of this utility model is to provide a kind of screw rod batch mixing head.
Problem to be solved in the utility model is the existing easy buildup of screw rod batch mixing head, can produce high shear, is not suitable for heat
The defect of sensitive materials.
To realize the purpose of this utility model, the technical solution adopted in the utility model is：
A kind of screw rod batch mixing head of the utility model, including conehead, spiral section a, U-type groove, spiral section b, pin section, cooling water
Hole, pin, screw channel and spiral shell rib, the taper of conehead is 60 degree, and spiral section a, spiral section b and pin section are sequentially provided with behind conehead,
Spiral section a and spiral section b are separated by U-type groove, and spiral section a and spiral section b are provided with identical screw channel and spiral shell rib, and spiral shell rib has 12
Alloy is coated with head, spiral shell rib, pin is arranged on pin section；Batch mixing head center is provided with cooling water hole, by being injected to cooling water hole
Cooling water can effectively reduce batch mixing head central temperature；Batch mixing head material is 38CrMoAlA, and conditioned processing：HB270-
290, the processing of outer surface via nitride, hardness HV>950, nitride layer depth is in 0.5-0.7mm.
Pin includes inner core, overcoat, bulge loop and scrobicular ring, and inner core is fixedly mounted on pin section, and inner core bottom is provided with bulge loop, outside
Set is internal to be provided with scrobicular ring, and overcoat is enclosed on inner core, and bulge loop is embedded on scrobicular ring, and overcoat can freely be rotated on inner core.
The utility model has the advantages that：Overcoat can freely be rotated on inner core, therefore material can not be accumulated on pin,
Solve pin section easily buildup the problem of；Batch mixing head center is provided with cooling water hole, can be with by injecting cooling water to cooling water hole
Effectively reduction batch mixing head central temperature, can take away the heat that high shear is produced；Batch mixing head material is 38CrMoAlA, and
Conditioned processing：HB270-290, the processing of outer surface via nitride, hardness HV>950, nitride layer depth is on 0.5-0.7mm, spiral shell rib
It is coated with alloy, therefore the mixing refining head is the characteristics of have more wear-resisting, long lifespan.
