Problems solved by technology

Although there are four compound rubber extruder heads now, in order to make the structure of the five compound rubber extruder unit with one extruder more compact and the layout reasonable, the extrusion ports of the five compound rubber extruder heads The size of the horizontal inclination, the size of the horizontal inclination of the parting surface of each mold body, and the length range of each flow channel cavity still need to be redesigned, that is, an optimally designed five-composite rubber extrusion head is required

Embodiment 1

[0029] 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.

[0030]figure 1 Shown is the five-composite rubber extruder head 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 through the upper mold 4. The hinge shaft is hinged with the middle mold 4, the lower middle mold 5 and the lower mold 6 are successively below the middle mold 4, and the middle and lower mold 5 and the lower...

Embodiment 2

[0040] The structure of this example is as follows figure 1 As shown, it is similar to Embodiment 1, except that the installation angles of each extrusion port and the parting surface of the die body, and the length of each runner cavity are different from Embodiment 1.

[0041] The installation angle of each extrusion port in this example is: the angle between the axis of the upper die extrusion port 8 and the horizontal plane ω 1 is 45°, the angle ω between the axis of the extrusion port 9 of the upper die and the horizontal plane 2 is 20°, the angle ω between the axis of the middle die extrusion port 10 and the horizontal plane 3 is -5°, the angle ω between the axis of the extrusion port 11 of the lower middle die and the horizontal plane 4 is -20°, the angle ω between the axis of the extrusion port 12 of the lower die and the horizontal plane 5 is -45°.

[0042] In this example, the angle θ between the parting surface and the horizontal plane between the upper mold 1 a...

Embodiment 3

[0045] The structure of this example is as follows figure 1 As shown, it is similar to Embodiment 1, except that the installation angles of each extrusion port and the parting surface of the die body, and the length of each runner cavity are different from Embodiment 1.

[0046] The installation angle of each extrusion port in this example is: the angle between the axis of the upper die extrusion port 8 and the horizontal plane ω 1 is 34°, the angle ω between the axis of the extrusion port 9 of the upper die and the horizontal plane 2 is 16°, the angle ω between the axis of the middle die extrusion port 10 and the horizontal plane 3 is 2°, the angle ω between the axis of the extrusion port 11 of the lower middle die and the horizontal plane 4 is -13°, the angle ω between the axis of the extrusion port 12 of the lower die and the horizontal plane 5 is -33°.

[0047] In this example, the angle θ between the parting surface and the horizontal plane between the upper mold 1 an...

Abstract

The present invention is a five-composite rubber extruder head, including an upper die, upper middle die one, upper middle die two, middle die, lower middle die, and lower die installed on the die base, and the die base is provided with a connecting extruder The barrel has five extrusion ports arranged in a saddle-back structure, and each extrusion port arranged obliquely connects the parting surface runner cavity between the mold bodies after mold closing. The angles between the axis of the upper die extrusion port, the upper middle die extrusion port, the middle die extrusion port, the lower middle die extrusion port, and the lower die extrusion port and the horizontal plane are 30°~45°, 10°~20°, respectively. °, 5°~-5°, -10°~-20°, -30°~-45°. The preferred schemes are 34°~38°, 16°~20°, 2°~-2°, -13°~-17°, -33°~-37°. The included angle between the parting surface and the horizontal plane between the matching mold bodies and the length of the flow channel cavity on the parting surface between the mold bodies are also given. Ensure the reasonable position of the connected extruder, optimize the layout, and facilitate installation and maintenance.

Description

technical field [0001] The invention relates to a rubber machine, in particular to a five-composite rubber extrusion head. 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 the exi...
