Description

Technical Field

[0001] The utility model relates to the technical field of wire reel manufacturing, in particular to a high-speed wire reel integrated hot pressing and forming device. Background Art

[0002] The wire reel is composed of a cylinder body and two disc bodies, and is hollow in the middle. The wire reel is used for the turnover of cable wires. With the increasing development of technology and the continuous expansion of the application scope of wire reels, many different types and materials of wire reels have been produced. Plastic wire reels are one of the widely used ones. In the production process of plastic wire reels, an integrated hot pressing and forming device is used for sizing production.

[0003] The plastic wire reel forming device uses a forming die to thermoplast the high-temperature plastic wire reel raw material. After thermoplasting, it needs to be cooled and formed. Most of the existing forming devices are provided with cold water pipes in the cold water pipe cavities at the bottom or side of the die, and the cold water in the cold water pipes circulates to take away the heat in the die cavity for cooling treatment. However, when the cold water in the cold water pipes absorbs the heat in the die cavity, it will also emit a certain amount of heat itself, and the heat accumulates in the cold water pipe cavity, resulting in the heat not being effectively dissipated, affecting the cooling effect.
