Embodiment 1
[0030]This example takes a five-composite rubber extruder unit equipped with five rubber extruders as an example. The five rubber extruders are 120, 150, 250, 250, and 150 respectively, that is, the screw diameter of the extruder They are 120mm, 150mm, 250mm, 250mm, 150mm respectively.
[0031] figure 1 Shown is the five-composite rubber extruder head device of the five-composite rubber extrusion unit in this example, including upper die 1, upper middle die one 2, upper middle die two 3, middle die 4, lower middle die 5 and lower die 6 , the middle mold 4 is connected with the mold base 7 as a whole, and the top of the middle mold 4 is the upper middle mold 2 3, the upper middle mold 1 2, the upper mold 1, the upper middle mold 2 3, the upper middle mold 1 2, and the upper mold 1. The upper hinge shaft is hinged with the middle mold 4, and below the middle mold 4 are the lower middle mold 5 and the lower mold 6, and the middle and lower mold 5 and the lower mold 6 are hinged ...
Embodiment 2
[0041] The structure of this example is as follows figure 1 As shown, it is similar to Embodiment 1, except that the installation angles of the parting surfaces of each mold body and the extrusion port, and the length of each runner cavity are different from Embodiment 1.
[0042] In this example, the angle θ between the parting surface and the horizontal plane between the upper mold 1 and the upper middle mold 1 1 is 55°, the angle θ between the parting surface and the horizontal plane between the upper middle mold 2 3 and the upper middle mold 1 2 2 is 40°, the angle θ between the parting surface and the horizontal plane between the upper middle mold 2 3 and the middle mold 4 3 is 10°, the angle θ between the parting surface and the horizontal plane between the middle mold 4 and the lower middle mold 5 4 is -30°, the angle θ between the parting surface and the horizontal plane between the lower middle mold 5 and the lower mold 6 5 is -55°.

Abstract
The invention discloses a five composite rubber extrusion machine head device. The five composite rubber extrusion machine head device comprises an upper mold, an upper middle mold I, an upper middle mold II, a middle mold, a lower middle mold and a lower mold, which are mounted on a mold seat, wherein five material extrusion ports which are arranged according to a pickaback structure on a machine cylinder of a continuous extrusion machine are formed on the mold seat, and all the material extrusion ports which are obliquely arranged are communicated with parting plane flow passage cavities among all mold bodies after mold closing. The included angles between the parting planes and the horizontal plane among all the mold bodies are 40 degrees to 55 degrees, 30 degrees to 40 degrees, 0 to 10 degrees, -15 degrees to -30 degrees and -40 degrees to -55 degrees respectively, preferably 48 degrees to 52 degrees, 30 degrees to 34 degrees, 4 degrees to 8 degrees, -20 degrees to -24 degrees and -48 degrees to -52 degrees. The five composite rubber extrusion machine head device further designs the matched included angles between the axial lines of the upper mold material extrusion port, the upper middle mold material extrusion port, the middle mold material extrusion port, the lower middle mold material extrusion port and the lower mold material extrusion port and the horizontal plane, as well as the lengths of the parting plane flow passage cavities among all the mold bodies. The five composite rubber extrusion machine head device can ensure the reasonable positioning of the extrusion machine linked with the five composite rubber extrusion machine head device, optimize layout and facilitate mounting and maintenance.
Description
technical field [0001] The invention relates to a rubber machine, in particular to a five-composite rubber extruder head device. Background technique [0002] In the existing tire production, generally speaking, most of the tread / sidewall semi-finished products are produced by two compound extruder units and three compound extruder units, and some high-grade tread / sidewall semi-finished products are produced Four compound extruders are used for production, but some treads / sidewalls produced by two, three and four compound extruders need to be laminated on the surface outside the machine. The dimensional accuracy of this kind of external lamination can no longer meet the dimensional accuracy and dynamic balance requirements of modern high-grade radial tires for their products. Therefore, the development of a five-composite extruder with more composite layers in the machine has become a high-end demand in the market. [0003] The five-compound rubber extrusion unit changes t...
