Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an extrusion mold for cable materials. Background Art

[0002] Existing extrusion molds for cable materials extrude cables to form them. When the cables are produced through components such as a die core, the cables have a tube core. At the same time, it is to prevent the position between the die core and the die sleeve from shifting, which affects the quality of cable forming. However, the cables are not cooled in time after the tube core is formed, which easily causes the tube core to be re-sealed before cooling. And it does not solve the problem that when the cable is produced too long, it cannot be discharged from the device in time only by the driving force of the device, resulting in the accumulation of cables in the device and affecting subsequent production. For example, a cable production extrusion mold disclosed in a Chinese patent, with the application number CN202322510585.9, although through the action of the limiting component, it effectively prevents the position between the die core and the die sleeve from shifting and affecting the quality of cable forming, and solves the problem that the position between the die core and the die sleeve is easily shifted due to external extrusion when extruding and forming the cable. However, it does not cool the cable in time after the tube core is formed, and at the same time, it does not consider that when the cable is produced too long, it cannot be pushed out of the device only by the extrusion component, resulting in the cables being stacked in the device and unable to be discharged, affecting the subsequent production of the cables, and the use has limitations.
