Problems solved by technology

[0004] Because the wall thickness of the integrated lamp housing is relatively thin and the cavity depth is relatively large, when the existing die-casting mold for manufacturing the integrated lamp housing is die-casted to the integrated lamp housing, the exhaust effect is poor, which affects the aluminum The fluidity and exhaust effect of the alloy metal liquid, while increasing the die-casting cycle, are also prone to poor phenomena such as pores and shrinkage on the surface of the integrated lamp housing

Abstract

The invention discloses a high exhaust type die-casting die for an integrated lamp shell, and belongs to the field of die-casting dies. A temperature change exhaust cavity and an air groove type mold core matched with the temperature change exhaust cavity are fixedly mounted on a lamp shell die-casting die body, and a temperature change honeycomb composite bag is matched with a supporting strip sinking type air groove so that the temperature change honeycomb composite bag can absorb airflow flowing in the supporting strip sinking type air groove, the exhaust speed of the supporting strip sinking type air groove is effectively increased, air in the die-casting forming gaps can be dragged, air residues in the die-casting forming gaps are reduced, and the die-casting forming gaps can rapidly form a vacuum-like state. While the flowing speed of aluminum alloy metal liquid is increased and the die-casting period is shortened, the influence of the air on the aluminum alloy metal liquid is effectively reduced, the flowing uniformity of the aluminum alloy metal liquid is improved, the defects such as air holes and shrinkage ribs on the die-casting integrated lamp shell are reduced, and the forming quality of the die-casting integrated lamp shell is effectively improved.

Description

technical field [0001] The invention relates to the field of die-casting molds, in particular to a high exhaust type die-casting mold for an integrated lamp housing. Background technique [0002] Die-casting mold is a tool for casting metal parts, a tool that completes the die-casting process on a special die-casting die forging machine. The basic process of die-casting is: the molten metal is first cast at low or high speed and filled into the cavity of the mold. The mold has a movable cavity surface, which is forged under pressure during the cooling process of the molten metal, which eliminates the shrinkage cavity of the blank. Loose defects also make the internal structure of the blank reach the broken grains of the forged state. The comprehensive mechanical properties of the blank are significantly improved. [0003] The integrated lamp housing is mostly made of aluminum alloy die-casting. It is widely used in lamps because of its lightness, compactness and fast heat ...
