Problems solved by technology

The upper cover sliding plate is usually made of copper-graphite alloy or tin-bronze alloy, which has high cost and small area, and is easy to wear. When the 1mm wear-resistant layer on the surface is worn away, it will affect the opening and closing of the mold, and even the pattern block will be stuck, causing Mold wear and scrap
As far as the current usage of tire molds is concerned, this sliding friction method has a large friction coefficient and a large force, which is easy to cause the upper cover opening slide to wear and fail, and the mold opening and closing process is not smooth, so the upper cover opening slide needs to be replaced frequently , leading to an increase in the maintenance cost of the mold

Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0015] combine figure 1 , figure 2 As shown, a tire mold can slide T-shaped block structure, including T-shaped block 1, cylindrical roller 2, long groove 3, bolt 4, lower bottom plate 5, cylindrical pin 6, T-shaped block 1 under the two sides of the shoulder There is a long groove 3, and the cylindrical roller 2 is connected to the lower bottom plate 5 through a cylindrical pin 6, and the lower bottom plate 5 is fastened to the inside of the long groove 3 by bolts 4.

[0016] combine figure 1 , figure 2 and image 3 As shown, when the tire mold is completely separated from the tread, the hot plate of the vulcanizer drives the upper cover 7 to move upward together. When it moves upward to a certain height, under the guiding action, the bow seat 9 relies on the cylindrica...

Abstract

The invention relates to the field of tire production equipment, in particular to a tire mold rolling T-shaped block structure, which comprises a T-shaped block, a cylindrical roller, long grooves, ascrew bolts, a lower bottom plate and a cylindrical pins, wherein the long grooves are formed at the lower side surface of the two sides of the ledge of the T-shaped block; the cylindrical roller is connected onto the lower bottom plate through the cylindrical pins; the lower bottom plate is fastened to the inside of the long grooves of the T-shaped block through the a screw bolts. The sliding friction between the T-shaped block and the upper cover is changed into rolling friction; the friction coefficient between of the T-shaped block and the upper cover is reduced, so that the mold opening and closing process is smoother; the stress state of the upper cover is improved; meanwhile, the upper cover opening slide plate opening part is eliminated.

Description

technical field [0001] The invention relates to the field of equipment for producing tires, in particular to a rolling T-shaped block structure of a tire mold. Background technique [0002] At present, most of the tire molds produced in China are radial tire active molds. In the tire mold, the T-shaped block plays the role of connecting the upper cover and the bow seat. The upper cover opening slide plate is located on the lower surface of the T-shaped block shoulder. Relying on the sliding friction between the T-shaped block and the sliding plate of the upper cover to realize the mold opening and closing process. The upper cover sliding plate is usually made of copper-graphite alloy or tin-bronze alloy, which has high cost and small area, and is easy to wear. When the 1mm wear-resistant layer on the surface is worn away, it will affect the opening and closing of the mold, and even the pattern block will be stuck, causing The mold is worn out and scrapped. As far as the cu...
