Problems solved by technology

[0003] The main structural components of the existing LED floodlights are aluminum die-casting shells, most of which are integrally formed by die-casting. Drill holes and install the LED light board on the aluminum shell with screws. When the aluminum shell works in a humid or corrosive environment for a long time, it is easy to cause the screws to rust on the aluminum shell, which not only affects the aluminum shell Excellent sealing effect, and it is difficult to quickly disassemble and repair the components inside the aluminum shell

Embodiment approach

[0028] As an embodiment of the present invention, the rubber sealing strip 6 is provided with an expansion chamber 61, and the rubber sealing strip 6 is provided with a plurality of frosted convex films 62; There is a gap cavity 63 between them, and the gap cavity 63 is connected to the expansion cavity 61 through the air guide groove; the expansion cavity 61 communicates with the extrusion cavity 71; When shrinking, the gas inside the extrusion cavity 71 will enter the expansion cavity 61, and then enter the gap cavity 63 inside the frosted convex film 62 through the expansion cavity 61, so that the frosted convex film 62 is expanded and squeezed to fit In the insertion cavity 51 , the frictional resistance between the rubber sealing strip 6 and the insertion cavity 51 is further improved, and the insertion stability of the rubber sealing strip 6 inserted into the insertion cavity 51 is further improved.

Abstract

The invention belongs to the technical field of die casting, and particularly relates to a die casting aluminum part. The die casting aluminum part comprises a housing aluminum part; the housing aluminum part and a supporting frame are both formed through die casting; the housing aluminum part is formed by mutually splicing two die-casting frames; rubber sealing strips are inserted into symmetrically arranged insertion cavities, and the two rubber sealing strips are mutually connected through a rubber clamping strip; a plurality of connecting holes are vertically formed in the inner side wallsof the two die-casting frames, and threaded rods are inserted into the connecting holes; nuts are in threaded connection with the two ends of the multiple threaded rods; the two ends of the threadedrod located in the middle of the die-casting frames are provided with the supporting frame, and the supporting frame is adjustably fixed on the threaded rod through nuts; inner cavity walls of the twodie-casting frames are provided with insertion sliding grooves respectively, and an LED lamp panel is slidably inserted into the insertion sliding grooves; and a lampshade is arranged on the outer side of the LED lamp panel. Holes do not need to be punched on the housing aluminum part, and the LED lamp panel is mounted on the housing aluminum part through screws, so that the use sealing effect ofthe housing aluminum part is improved.

Description

technical field [0001] The invention belongs to the technical field of die-casting parts, in particular to a die-casting aluminum part. Background technique [0002] Die casting is a metal casting process characterized by the application of high pressure to molten metal using the cavity of a mold. Molds are usually machined from stronger alloys, a process somewhat similar to injection molding. Most die castings are ferrous, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. [0003] The main structural components of the existing LED floodlights are aluminum die-casting shells, most of which are integrally formed by die-casting. Drill holes and install the LED light board on the aluminum shell with screws. When the aluminum shell works in a humid or corrosive environment for a long time, it is easy to cause the screws to rust on the aluminum shell, which not only affects the aluminum shell At the same time, it is difficult to quickl...
