Problems solved by technology

To sum up, the above-mentioned connection method has the following problems: (1) The large thickness of the pattern layer increases the size of the entire pattern block, which in turn increases the size of the entire mold and increases various related costs; (2) The connection between the pattern layer and the skeleton layer The integrity of the together is not good; (3) There is a gap that is difficult to eliminate between the pattern layer and the skeleton layer, and the thermal conductivity of the pattern block is poor; (4) The joint surface combining the pattern layer and the skeleton layer is difficult to process

Embodiment 1

[0034] Such as image 3 As shown, the steel-aluminum composite pattern block includes a skeleton layer 11 and a pattern layer 12, wherein the pattern layer 12 is located on the inner side of the pattern block, and its function is to form a pattern. It is made of an aluminum alloy with low hardness and strength, and the skeleton layer 11 is located The outer side of pattern block, its effect is to constitute the overall skeleton of pattern block, and it selects the steel material that hardness and intensity are higher than pattern layer for use to make, and 13 is a steel sheet.

[0035] The pattern blocks in this embodiment are formed by integral casting, that is, the entire pattern circle is cast at one time, and then divided into several pattern blocks equally along its circumferential direction. Such as figure 1 Shown, the aluminum alloy 9 of melting state is filled in the crucible 8 of melting furnace 7 li, the upper fixed furnace cover 6 of melting furnace 7 and crucible ...

Embodiment 2

[0051] Figure 4 It is a process in which a "T"-shaped groove is set on the inner surface of the skeleton layer that is connected with the pattern layer, and the molten aluminum alloy flows into the "T"-shaped groove under the action of pressure during casting, and is cooled to form an aluminum pattern layer. The center and the steel skeleton layer are firmly joined together.

[0052] Others are the same as embodiment 1.

Embodiment 3

[0054] Figure 5 On the inner surface of the skeleton layer joined with the pattern layer, a "roller flower knife" is used to roll to form uneven and regular patterns, and the molten aluminum alloy flows into the concave pattern of the steel skeleton layer under the action of pressure during casting. In the process of cooling to form the aluminum pattern layer, it is firmly bonded with the steel skeleton layer.

[0055] Others are the same as embodiment 1.

Abstract

The invention relates to a manufacturing method for a radial tyre adjustable die pattern block, in particular to a casting method for the steel-aluminium composite pattern block. The invention aims at overcoming the defect that the existing manufacturing method of the existing composite pattern block has complex process and difficult processing and provides a casting and forming method for the radial tyre adjustable die steel-aluminium composite pattern block. In the method, the aluminium alloy in melting state is directly cast on a steel framework layer so as to form an aluminium-quality pattern layer; the pattern block has high pattern forming precision in the manufacture process, short manufacturing period and low manufacturing cost; meanwhile, the cast pattern layer is thin; the steel framework layer and the aluminium-quality pattern layer have no gaps and are firmly combined with each other; the integral rigidity is high and the service life of the pattern block is prolonged.

Description

technical field [0001] The invention relates to a manufacturing method of a pattern block of a radial tire active mold, in particular to a casting method of a steel-aluminum composite pattern block. Background technique [0002] The outer contour of the radial tire is molded by the pattern circle in the active mold and the sidewall plates combined on the upper and lower sides of the pattern circle. The pattern circle is formed by several pattern blocks distributed along the circumference, and the inner surface of the pattern blocks has a pattern, which can mold the crown pattern of the tire. Sidewall panels are used to mold the shape, graphics and text of the sidewall of the tire. Steel is usually used to manufacture the pattern blocks of the all-steel radial tire active mold, and aluminum alloy is used to manufacture the pattern blocks of the semi-steel radial tire active mold. The problem with this method of making pattern blocks with a single metal or alloy material is: ...
