Description

Technical Field

[0001] The utility model relates to the technical field of rubber block casting moulds, and more specifically, it relates to a novel casting mould for blast furnace rope wheel rubber blocks. Background Art

[0002] The ironmaking blast furnace sheave is an important part of the blast furnace hoist system. It carries the steel wire rope for continuous operation and requires high reliability and long service life. The failure and wear of the sheave is mainly caused by the friction between the sheave chute and the steel wire rope. Therefore, wear-resistant rubber blocks are embedded in the rope groove. The rubber blocks have strong wear resistance, high strength, good elasticity and anti-aging. The friction between the steel wire rope and the rope groove is greatly reduced, and the service life of the sheave and the steel wire rope is increased.

[0003] The production of rubber blocks requires a mold to be cast and formed in one step. Special polyurethane is used as the main raw material. After being melted into liquid, it is mixed with auxiliary materials and poured into the corresponding mold for casting and molding. Since the rubber block has a certain curvature and a semicircular groove on the surface, and the original mold is an integral structure, the casting and production are troublesome, the operation is inconvenient, the demoulding is difficult, the efficiency is low, and the manufacturing cost is high.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a novel casting mold for blast furnace rope pulley rubber blocks. Utility Model Content

[0017] 1. In the utility model, by setting the mold frame and the mold core, the mold adopts a split design to solve the demoulding problem, and the mold manufacturing cost is low. At the same time, the mold can be laid flat and adopts a self-leveling product manufacturing process to improve production efficiency;

[0018] 2. In the utility model, by providing a trapezoidal groove, the left and right side walls of the mold core can fit the inner wall of the trapezoidal groove, so that the mold core can be fixedly installed at the inner rear end of the trapezoidal groove, and the movable groove is aligned with the slot on the left and right. By rotating the bolt, the insert in the movable groove can be pushed to the inside of the slot, and the mold core can be further fixed to the inside of the mold frame, so that the bottom surface of the mold core is flush with the bottom surface of the mold frame to avoid leakage of raw materials.

[0019] 3. In the utility model, a knocking ball is provided. Pulling the handle can drive the rotating block to rotate in the fixed block, and the angle position of the spring on the top surface of the mold frame can be adjusted.
