Description

Online repairing platform for pulley structure type mould

Technical Field

Background

A die casting machine is a machine for pressure casting. Comprises a hot pressing chamber and a cold pressing chamber. The latter two types are respectively straight type and horizontal type. The die casting machine hydraulically shoots molten metal into a die under the action of pressure to be cooled and molded, and after the die is opened, a solid metal casting can be obtained and is initially used for die casting types. With the progress of scientific technology and industrial production, particularly with the development of industries such as automobiles, motorcycles, household appliances and the like, the die casting technology has been developed extremely rapidly.

In the production maintenance of an actual die casting machine, on-site maintenance personnel can frequently use a die-repairing platform to maintain and maintain a die of the die casting machine, and the telescopic structure of the existing die-repairing platform is usually of two types, namely an oil cylinder direct driving telescopic structure or a synchronous belt structure driving telescopic structure. The extension length of the platform is constrained by the whole length of the platform, namely the extension length of the platform is smaller than the whole length of the die repairing platform. The disadvantage of this constraint is that in environments where space is limited, particularly when the die of an oversized die casting machine is large, the extension of the die-repair platform cannot reach the location where maintenance is required at the distal-most end of the die.

The existing die repairing platform telescopic structure is insufficient in extension length and cannot be suitable for repairing large dies.
