Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The purpose of the utility model is to provide a kind of abrasive disk type oil to heat head, of the existing technology to solve the problems, such as,
Overcome existing head as volume is big, process of the molten plastic in head compared with it is long the defects of caused by heating power consumption it is big,
The problems such as head membrane production capacity is low realizes energy-efficient production.
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
The present embodiment provides a kind of abrasive disk type oil to heat head, and as shown in Figs. 1-2, including ontology 3, ontology 3 are cylindric
And it is intermediate equipped with cylindrical boss, the boss top of ontology 3 is fixedly installed mouth mold 1, can be fixed by bolts, can also adopt
It is fixed with pressure ring.The center of ontology 3 is equipped with feed inlet 9, and feed inlet 9 is connect with the discharge port of extruder, with charging
The center of mouth is origin, has * type runner to the circumferencial direction homogeneous radiation of ontology 3, runner is 16, and ontology 3 is externally provided with adjustment
Ring 2, adjustment ring 2 are fitted closely along the outer circle upper surface of ontology 3, there are gap between the boss of ontology 3, adjustment ring 2 and mouth mold,
16 runners are connected to the gap, and molten plastic flows into the gap along 16 runners through feed inlet, and molten plastic is shunted through runner
Pressure, uniform flow.The bottom of mouth mold 1 is equipped with an inclined-plane, is gradually reduced from bottom to top in inclined-plane position gap.Adjustment ring
2 are equipped with 6 adjustment bolts 4, can be by adjusting the gap between the adjusting mouth mold 1 of adjustment bolt 4 and adjustment ring 2.Ontology 3
4 ventholes 8 for running through ontology 3 are inside equipped with, compressed air is passed through from the bottom of ontology 3, is blown upwards.
Further, heat-conducting oil pipes 5 are additionally provided in above-described embodiment, heat-conducting oil pipes 5 pass through ontology 3 and ontology 3 is arranged in
Top is additionally provided with annular conduction oil channel 7 in the inside of adjustment ring 2, conduction oil is passed through by heat-conducting oil pipes 5, using this side
Formula heating, temperature are uniformly and mild.
