Die casting device of tuner aluminum shell and machining method of tuner aluminum shell

Abstract

The invention discloses a tuner aluminum shell die-casting device which comprises a device body, the device body is provided with a bottom box body, a hydraulic mechanism box body is arranged above the bottom box body, the device body is provided with a die-casting operation table structure, and a die-casting die is arranged above the die-casting operation table structure. An upper die-casting die is arranged on the bottom face of the pressure sensor, and the upper die-casting die and the pre-pressing plate are fixedly installed through the effect of an installation support. During die casting, a tuner aluminum shell assembly can be effectively subjected to die casting under the action of the device body, the connection relation of the die can be effectively enhanced through the mortise and tenon joint structure, and the phenomenon that the die is loosened in the die casting process is avoided; and the mode of the integrated structure between the die set and the lower die-casting die ensures that the die set is tightly connected with the lower die-casting die, the structure is stable, the situation that the die falls off and is damaged in the die-casting process is avoided, and the use effect is good.

Description

technical field [0001] The invention relates to the field of high-frequency head processing, in particular to a die-casting device for a high-frequency head aluminum shell and a processing method thereof. Background technique [0002] The internal circuit of the tuner includes a low-noise amplifier and a down-converter, which completes the functions of low-noise amplification and frequency conversion. It not only amplifies the high-frequency signal output by the feed source, but then reduces the frequency to the first intermediate frequency signal of 950-2150MHz. There are usually 24 TV channels on each satellite. In order to make full use of these channels and avoid mutual interference of adjacent channels, the order of channels is usually separated into single and double, and electromagnetic waves of different polarizations are launched respectively. [0003] The shell part of the existing high-frequency head is generally processed by die-casting or stretching, but the exi...

Problems solved by technology

[0003] The shell part of the existing high-frequency head is generally processed by die-casting or stretching, but the existing die-casting mold needs to be replaced frequently when the mold is installed on the module, because different The die-cast aluminum shell of the structure is processed by different molds, but the installation of the existing molds is very troublesome, because most of them are fixed by using multiple brackets and screws, but this structure is relatively oily during use. There are many inconveniences, such as inconvenient installation, so it needs to be improved
