technical field

The invention belongs to the technical field of die-casting parts, in particular to a die-casting aluminum part.

Background technique

Die casting is a metal casting process characterized by the use of a mold cavity to apply high pressure to molten metal. Molds are usually machined from stronger alloys, a process somewhat similar to injection molding. Most die castings are free of iron, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys.

The main structural components of the existing LED flood light are aluminum die-casting shell aluminum parts, most of which are integral die-casting molding structures. 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. The sealing effect is good, and it is difficult to quickly disassemble and repair the components inside the aluminum part of the shell.

In view of this, in order to overcome the above technical problems, our company has designed and developed a die-casting aluminum part, and made a special die-casting aluminum part suitable for LED floodlights, which solved the above-mentioned technical problems.

SUMMARY OF THE INVENTION

In order to make up for the deficiencies of the prior art, the present invention proposes a die-casting aluminum part. The present invention is mainly used to solve the problem that the main structural components of the existing LED flood light are aluminum die-casting aluminum parts of the shell, and the LED lamp board needs to be installed on the shell. When it is installed, it is necessary to drill holes on the aluminum parts of the casing, and install the LED light board on the aluminum parts of the casing by screws. When the aluminum parts of the casing work in a humid or corrosive environment for a long time, it is easy to cause the screws to rust to the aluminum parts of the casing. It not only affects the sealing effect of the aluminum parts of the shell, but also makes it difficult to quickly disassemble and repair the components inside the aluminum parts of the shell.

The technical solution adopted by the present invention to solve the technical problem is as follows: a die-casting aluminum part according to the present invention includes an aluminum casing part, an LED lamp board, a lampshade and a supporting frame; the casing aluminum part and the supporting frame are both die-casting. ; The outer shell aluminum parts are spliced together by two die-casting frames, and the symmetrical surfaces of the two die-casting frames are provided with plug-in cavities; the symmetrically opened plug-in cavities are all plugged with rubber sealing strips, and the two rubber seals The bars are connected to each other by rubber clips; the rubber clips are located between two symmetrically arranged die-casting frames; the inner side walls of the two die-casting frames are vertically provided with a plurality of connecting holes, and the plurality of connecting holes A threaded rod is inserted into the inside; the two ends of the plurality of threaded rods are threadedly connected with nuts, and the plurality of the threaded rods are inserted into the rubber clips and the rubber sealing strip; the threaded rods located in the middle of the die-casting frame The two ends of the rod are installed with support frames, and the support frames can be adjusted and fixed to the threaded rod through nuts; the inner cavity walls of the two die-casting frames are provided with plug-in chutes, and the plug-in chutes are slidably plugged with LED light board; the outer side of the LED light board is provided with a lampshade;

When working, when the LED light board needs to be installed on the aluminum part of the housing, the installer first separates the two die-casting frames, and then slides the LED light board into one of the die-casting frames into the plug-in chute, and then slides the rubber clip. The rubber sealing strip on one side wall is inserted into the insertion cavity of the die-casting frame, and at the same time, multiple threaded rods are inserted into the connecting holes of the die-casting frame on which the LED light board has been installed in sequence, and then the installer will insert another die-casting frame. The plug-in chute on the top is slid and sleeved to the outside of the LED light board, and the connecting holes on the die-casting frame are aligned with a plurality of threaded rods, and then the installer pushes the other die-casting frame to move to the side of the fixed previous die-casting frame, When the rubber sealing strip on the other side of the rubber clip is inserted into the socket cavity of the die-casting frame that is installed in a sliding way, adjust the distance that the multiple threaded rods protrude from the outer wall of the die-casting frame, and then the operator's nut and washer are socketed into the two ends of the threaded rod. Then, the nuts on both sides of the aluminum parts of the casing are synchronously twisted by a wrench, and then the die-casting frames spliced with each other are fixedly connected, and the rubber sealing strips are inserted into the socket cavity to fix the rubber clips to prevent symmetrical extrusion. The extrusion force of the die-casting frame on the rubber clip is too large, which will cause the rubber clip to be squeezed out or squeezed out of position, thereby affecting the sealing effect of the die-casting frames spliced to each other; then the support frame is fixed to the shell by nuts. The threaded rod in the middle of the aluminum part enables the support frame to support and fix the aluminum part of the shell; at the same time, the aluminum part of the shell formed by splicing each other can quickly fix the LED light board without drilling holes in the aluminum part of the shell, The LED light board is mounted on the aluminum shell of the shell by screws, thereby improving the sealing effect of the aluminum shell of the shell. When the components installed inside the aluminum shell of the shell need to be repaired, the operator only needs to die-cast one side of the aluminum shell. The die-casting frame can be separated by dismantling the nut on the outer wall of the frame, which facilitates the safe maintenance of the die-casting frame or the internal components.

When the outer wall is used, the elastic buffer ring continues to squeeze the sealing plug by pressing the slider, so that the sealing plug can be in a stable state, and then part of the lubricating liquid in the rotating screw can penetrate into the liquid film, so that the threaded rod can be lubricated with the connecting hole. It can effectively prevent the threaded rod from being inserted into the die-casting frame for a long time due to the long length of the threaded rod, which will cause the threaded rod to rust and bond to the inside of the die-casting frame, thus making the die-casting frame difficult to separate from each other. When the frame is separated, the operator can turn the nut back and forth, so that the elastic buffer ring can slide back and forth on the threaded rod.

The corrugated shape of the extrusion cavity and the outer wall can make the rubber clips only shrink instead of expanding to the outside, which effectively prevents the rubber clips from being squeezed due to the excessive extrusion force of the die-casting frame on the rubber clips. The phenomenon of deformation not only affects the elastic buffering effect of the rubber clip, but also affects the sealing effect of the rubber clip on the die-casting frame.

Preferably, the rubber sealing strip is provided with an expansion cavity, and a plurality of frosted convex films are arranged on the outside of the rubber sealing strip; a gap cavity is provided between the frosted convex film and the rubber sealing strip, and the gap cavity is It is connected to the expansion cavity through the air guide groove; the expansion cavity is communicated with the extrusion cavity; during operation, when the rubber clip is contracted by the extrusion force, the gas inside the extrusion cavity will enter the expansion cavity, and then pass through the expansion cavity.
