Abstract

The invention relates to the technical field of molds, and particularly discloses a telescopic hot runner structure, an injection mold and a working method thereof. The telescopic hot runner structurecomprises a connecting hot nozzle and a first hot nozzle, a second hot nozzle which can move along the edge line direction of the inner wall of the first hot nozzle is arranged in the first hot nozzle, a heating piece is arranged on the second hot nozzle, one end of the second hot nozzle extends out of an opening of the first hot nozzle, the other end of the second hot nozzle is provided with a movable transition joint for telescoping to change length, the movable transition joint is sleeved with a sealing member, the temperature of a molten material is controlled through a heating element, and then the material is conveyed to the mold through the movable transition joint, the first hot nozzle and the connecting hot nozzle in sequence for injection molding, so that the moving distance requirements of different molds in opening and closing changes can be met, meanwhile, the phenomenon of glue leakage is avoided through the sealing element, and the problem that glue leakage can occur ina hot runner structure adopted by a mold in an existing injection molding process is solved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a stretchable hot runner structure, an injection mold and a working method thereof. Background technique [0002] Injection molding technology, as a method of producing industrial products, usually uses materials to make products of various shapes through molding dies. At present, with the development of injection molding technology to this day, the technology of many injection molds has been relatively mature, providing a large number of products for the society and enriching people's lives. [0003] However, there are still some problems in the current injection mold. For example, during the injection molding process, the runner part produces redundant nozzles (also known as soup gates, gates), and these nozzles must be re-broken before being put into production, which affects production efficiency. , At the same time, due to the secondary processing of the material, it will de...
