Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum profile processing devices, in particular to a mold cooling device for aluminum profile production. Background Art

[0002] Aluminum profiles are formed by extrusion, but during the extrusion process, the deformation and friction of the metal will cause the extrusion temperature of the alloy to rise, and the degree of temperature rise will increase with the increase of extrusion speed. The increase in extrusion temperature will bring many adverse effects to the production of alloy profiles, such as the decline of mechanical properties of profiles, surface oxidation changes, and even thermal cracking. At the same time, it will also cause the plasticity and toughness of the mold to change, causing mold failure, resulting in longitudinal cracks of the mold cavity or wear of the forming cavity and mold hole, causing the size and shape errors of the extruded parts to exceed the allowable value. Therefore, during the alloy extrusion forming process, it is necessary to use a cooling device to cool the mold.

[0003] Existing cooling devices for extrusion dies still have the following deficiencies: Existing cooling devices are mostly air cooling or direct spray cooling. On the one hand, the cooling effect of air cooling is poor and cannot achieve effective cooling effect. It is also easy to have uneven cooling affecting product quality. On the other hand, direct spray cooling is not easy to collect coolant, and it is also inconvenient to clean the mold, and the practicality is low.

[0004] Through the search, the applicant found:

[0005] Patent (201510993004.9) This document discloses an extrusion die, which consists of a die surface and a die pad. The die surface is provided with a die working zone, an air guide groove and an air inlet. The inert gas is argon, which flows into the die working zone from the air inlet of the die surface. However, the purpose of this invention is mainly to avoid the generation of aluminum oxide particles on the surface of the extruded profile, and the die surface is not a detachable structure. In particular, the device does not cool down the overheated area in the mold, and has a weak ability to control the temperature of the profile near the working zone and the metal in the mold, and the cooling effect is not good.
