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 extrusion head of the rubber extruder is required

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 extruder heads of the five composite rubber extrusion units 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, middle die The mold 4 is connected with the mold base 7 as a whole, 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 2, and the upper mold 1 through the upper hinge The 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 mold 6 are hi...

Embodiment 2

[0041] The structure of this example is as follows figure 1 As shown, it is similar to Embodiment 1, except that the lengths of the flow channel chambers are different, and the installation angles of the extrusion ports and the parting surface of the mold body are different from Embodiment 1.

[0042] The length L of the runner cavity on the parting surface between upper die 1 and upper middle die 1 in this example 1 is 550mm, the length L of the runner cavity on the parting surface between upper middle die 1 2 and upper middle die 2 3 2 is 550mm, the length L of the runner cavity on the parting surface between the middle die 4 and the upper middle die 2 3 is 400mm, the length L of the parting surface runner cavity between the middle mold 4 and the lower middle mold 5 4 is 400mm, the length L of the parting surface runner cavity between the lower die 6 and the lower middle die 5 5 is 400mm.

[0043] The installation angle of each extrusion port in this example is: the angl...

Embodiment 3

[0046] 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.

[0047] The length L of the runner cavity on the parting surface between upper die 1 and upper middle die 1 in this example 1 is 650mm, the length L of the runner cavity on the parting surface between upper middle die 1 2 and upper middle die 2 3 2 is 650mm, the length L of the runner cavity on the parting surface between the middle mold 4 and the upper middle mold 2 3 is 580mm, the length L of the parting surface runner cavity between the middle mold 4 and the lower middle mold 5 4 is 580mm, the length L of the parting surface runner cavity between the lower die 6 and the lower middle die 5 5 It is 630mm.

[0048] The installation angle of each extrusion port in this example is: the angle between the axis...

Abstract

The invention discloses five composite extrusion heads of a rubber extruder. The five composite extrusion heads of the rubber extruder comprise 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 installed on a mold base; five material extruding openings connected with an extruder barrel and distributed in a riding structure are formed on the mold base; the material extruding openings obliquely arranged are communicated with parting surface runner cavities among all closed molds, wherein the lengths of the parting surface runner cavities among the molds are respectively 550-780mm, 550-680mm, 400-670mm, 400-670mm and 400-670mm, and preferably are 650-700mm, 650-670mm, 580-620mm, 580-620mm and 630-670mm. The invention also designs included angles between axles of the upper mold material extrusion opening, an upper middle mold material extrusion opening, a middle mold material extrusion opening, a lower middle mold material extrusion opening and a lower mold material extrusion opening which are matched with the five composite extrusion heads of the rubber extruder with the horizontal level and included angles between parting surfaces among the molds and the horizontal level. The five composite extrusion heads of the rubber extruder guarantee the reasonable position of a linked extruder, optimize the layout, and are convenient to install and maintain.

Description

technical field [0001] The invention relates to a rubber machine, in particular to a five-composite extruder head of a rubber extruder. 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 ch...
