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 mold for an integrated lamp housing, which belongs to the field of die-casting molds. A temperature-variable exhaust cavity and an air cavity matched with the temperature-variable exhaust cavity are fixedly installed on the lamp housing die-casting mold body. The trough-type core is matched with the submerged air groove through the temperature-changing honeycomb composite bag. The temperature-changing honeycomb composite bag can absorb the airflow flowing in the submerged air groove, effectively improving the submerged air groove of the branch. The exhaust speed of the air groove can be improved, and the air in the die-casting gap can be pulled to reduce the residual air in the die-casting gap, so that the die-casting gap can quickly form a vacuum state, and the flow rate of the aluminum alloy metal liquid can be increased. While shortening the die-casting cycle, it can also effectively reduce the influence of air on the aluminum alloy metal liquid, improve the uniformity of the flow of aluminum alloy metal liquid, reduce the occurrence of air holes and shrinkage ribs on the die-casting integrated lamp housing, and effectively improve the quality of the die-casting integrated lamp. The molding quality of the shell.

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 a 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 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 dissi...
