Abstract
The utility model discloses a machine head of a rubber layer extruder for rubber hoses and relates to a unit of a rubber extruder. The machine head comprises a machine head flange, a machine head body, a runner core, a machine head core, a die core and a die sleeve, wherein a spiral runner is arranged on the surface of the runner core; the surface of the starting section of the runner core is matched with the inner surface of the machine head, and a spiral concave runner is arranged on the surface of the starting section of the runner core; the surface of the middle section of the runner core is a smooth surface, and a cavity is formed by the surface of the middle section of the runner core and the inner surface of the machine head; and spiral concave runners with different depths are arranged at the output section of the runner core. In the machine head, by adopting the spiral runners, the mixture degree of melted rubber materials inside the machine head is improved, the pressure inside the machine head is increased, the materials are mixed uniformly, and the flowing of the materials is smooth.
Description
Technical field
The utility model relates to a kind of Rubber Extruder parts, especially a kind of rubber tube glue-line cross-head.
Background technology
The glue-line cross-head of existing small-sized rubber tube generally includes head flange, handpiece body, runner core, head core, core rod and die sleeve; Under the effect of extruder screw; The rubber mass of molten condition flows between handpiece body and runner core; Extrude through the core rod of extruder head and the annular extrusion between the die sleeve, stick to the inner tube surface of rubber tube and form rubber layer.This cross-head, because the surface between handpiece body and the runner core all is a smooth surface, the pressure of formation is little, velocity ratio is very fast, but it is inhomogeneous the sizing material mixing to occur, and the not smooth phenomenon that flows.The glue-line quality that forms like this is unreliable, sometimes even can stop up runner, needs the labor cleaning, and manipulation strength is big, and production efficiency is low.
The utility model content
The technical problem that the utility model will solve provides the molten rubber material, and batch mixing evenly in its runner, unimpeded a kind of rubber tube glue-line cross-head flows.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
It comprises head flange, handpiece body, runner core, head core, core rod and die sleeve, is provided with spiral flow channel at said runner wicking surface.
The The initial segment surface of said runner core cooperates with the inner surface of handpiece body, and is provided with spiral indent runner on the The initial segment surface; The middle section surface of runner core is a smooth surface, and forms a cavity together with the inner surface of handpiece body; The deferent segment of runner core is provided with the different spirality indent runner of the degree of depth.
Adopt the beneficial effect that technique scheme produced to be: spiral flow channel has been strengthened molten rubber mass mixability therein, and has increased pressure wherein, makes batch mixing even, and it is unimpeded to flow.The stage casing smooth surface, and form cavity, make compound be unlikely to overheated carbonization, and it is unimpeded to flow.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Wherein, 1-head flange; The 2-handpiece body; 3-runner core; 4-head core; The 5-core rod; The 6-die sleeve; The 7-The initial segment; 8-indent runner; The 9-stage casing; The 10-deferent segment.
The specific embodiment
The utility model comprises head flange 1, handpiece body 2, runner core 3, head core 4, core rod 5 and die sleeve 6, is provided with spiral flow channel on said runner core 3 surfaces.
The initial segment 7 surfaces of said runner core 3 cooperate with the inner surface of handpiece body 2, and are provided with spiral indent runner 8 on The initial segment 7 surfaces; 9 surfaces, stage casing of runner core 3 are smooth surface, and form a cavity together with the inner surface of handpiece body 2; The deferent segment 10 of runner core is provided with the different spirality indent runner of the degree of depth.
The molten rubber mass gets into through head flange 1 in the spirality indent runner 8 of runner core 2 under the effect of extruder screw, successively through its The initial segment 7, stage casing 9 and deferent segment 10, gets into the extrusion between core rod 5 and the die sleeve 6 and extrudes.Spiral flow channel has been strengthened molten rubber mass mixability therein, and has increased pressure wherein, makes batch mixing even, and it is unimpeded to flow.Stage casing 9 smooth surfaces, and form cavity, make compound be unlikely to overheated carbonization, and it is unimpeded to flow.
Claims (2)
1. rubber tube glue-line cross-head, it comprises head flange, handpiece body, runner core, head core, core rod and die sleeve, it is characterized in that being provided with spiral flow channel at said runner wicking surface.
