Abstract
The utility model discloses a flow splitter for a machine head, which comprises a conical or cylindrical flow splitter body. Flow path groups are arranged on the surface of the flow splitter body; the flow path groups include a first flow path group formed by two flow paths in bifurcation and a second flow path group formed by two flow paths arranged at the tail ends of the two flow paths of the first flow path group respectively in bifurcation; the flow paths become shallower in depth to enable the pressure of fusion bodies to be fully relieved during the process of extruding the fusion bodies; two groups of flow paths smoothly transit, and the bottom sides of grooves are in the shape of an arc; and a circular-arc-shaped equalizing ring is arranged between the second flow path group and an outlet of the flow splitter body. Due to the adoption of the flow splitter, when the fused plastic polymers flow through the flow splitter to the die of the machine head, the resistance of material flow applied on fused plastic polymers can be reduced and the pressure is fully relieved. Therefore, the flow splitter has the advantages of balanced flow, stable volume, even flow speed and constant temperature, thereby ensuring the stability of the product quality.
Description
Technical field
The utility model relates to a kind of shunt, relates in particular to a kind of electric wire cross-head shunt.
Background technology
At present, the design that the runner of known electric wire cross-head shunt adopts is: become the form of one-to-two in the surface design of shunt, its flow is wayward.Plastic polymer after the fusion relies on the manual adjustment shunt and the gap of shell to guarantee stablizing of product when flowing velocity is slow in runner.And when flowing velocity was accelerated, original equilibrium state was just destroyed, needed to adjust separately, was not easy to steady production, also was difficult to guarantee product quality.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of liquation that can keep balanced mobile, the flow divider for nose that improves the quality of products.
The utility model provides a kind of flow divider for nose, comprise conical shunt body, on the surface of described shunt body, be provided with the runner group, described runner group comprises the first flow group that becomes forked to constitute by two runners, offers the second runner group that becomes forked to constitute by two runners respectively at the end of each runner of described first flow group.
Described shunt body is cylindrical or for conical, the tapering of described conical shunt body is 1 °～10 °.
Two runners of described first flow group are the angle of certain number of degrees each other; Two runners of the described second runner group are the angle of certain number of degrees each other.And the line between the end of first group of runner and the second group of flow field end, the helical angle of its left and right directions respectively is 90 °.
The runner of described first flow group runner and the described second runner group is provided with from deep to shallow, makes molten mass in the process of extruding, and pressure obtains fully balanced release, to guarantee the even of coating layer, thickness unanimity.
Joint portion in described first flow group and the described second runner group is formed with groove, and the cross section of described groove is circular arc.
The runner of the runner of described first flow group and the described second runner group seamlessly transits, and the groove bottom side is circular arc.Two groups of runners are streamlined and seamlessly transit, and avoid the dead angle buildup.
To the grading ring that is provided with circular arc between the outlet of described shunt body, make molten mass pressure before finally extruding obtain further evenly discharging in the described second runner group, stability is more secure.
The utility model improves on existing shunt, the plastic polymer that can solve effectively after the fusion obtains balancedly flowing in runner, in flow process, its pressure can be discharged equably, when Zhongdao mouth mould was layed onto heart yearn with plastic polymer, its thickness and the uniformity can be guaranteed.And when flowing velocity changes, can improve the function of shunt runner, its equilibrium state also can not be affected, and reaches the beneficial effect of steady production.

Embodiment
As shown in Figures 1 to 4, the utility model flow divider for nose, comprise shunt body 1, on the surface of shunt body 1, be provided with the runner group, the runner group comprises by two runners 21,22 one-tenth first flow groups 2 that forked constitutes, and offers respectively by two runners 31,32 one-tenth second runner groups 3 that forked constitutes at the end of each runner 21,22 of first flow group 2.
Wherein, shunt body 1 is cylindrical or is taper shape that the tapering of conical shunt body is 1 °～10 °.Two runners 21,22 of first flow group are the angle of certain number of degrees; Two runners of the second runner group 3 also are the angle of certain number of degrees, and it is streamlined that runner becomes, and do not stay the dead angle, transitions smooth, and groove is in the arc-shaped, the discharge uniform balance.And the line between the end of first group of runner and the second group of flow field end, the helical angle of its left and right directions respectively is 90 °.Joint portion in the first flow group 2 and the second runner group 3 is formed with groove 5, and the cross section of groove 5 is circular arc.The runner of the runner of first flow group and the second runner group is provided with from deep to shallow, and as shown in Figure 3, A point and B point are provided with from deep to shallow, make molten mass in the process of extruding, and pressure obtains fully balanced release, to guarantee the even of coating layer, thickness unanimity.
To the grading ring 4 that is provided with circular arc between the outlet of shunt body, make molten mass pressure before finally extruding obtain further evenly discharging in the second runner group 3, stability is more secure.
