Description

Technical Field

[0001] The invention relates to the technical field of die-casting shaping of aluminum alloy structural parts, and in particular to a die-casting shaping device and a process thereof for producing semiconductor aluminum alloy structural parts. Background Art

[0002] With the rapid development of the semiconductor industry, aluminum alloy structural parts are widely used in the manufacture of various semiconductor equipment due to their excellent properties, such as good electrical conductivity, thermal conductivity, light weight and certain mechanical strength. Semiconductor aluminum alloy structural parts are usually produced by die casting, which can quickly inject liquid aluminum alloy into the mold cavity to form it into the desired shape. After the semiconductor aluminum alloy structural parts are die-cast, some semiconductor aluminum alloy structural parts will be deformed, resulting in the flatness of the semiconductor aluminum alloy structural parts not meeting the quality requirements. In order to make the deformed semiconductor aluminum alloy structural parts meet the quality requirements, it is necessary to use a shaping device to perform hydraulic shaping on them.

[0003] However, when the traditional hydraulic shaping device performs downward shaping processing on the die-casting, it is necessary to first place the die-casting to be shaped on the lower die, and then move the upper die downward with the telescopic rod of the hydraulic cylinder, and then press down the die-casting to be shaped. When replacing the die-casting, it is necessary to wait until the previous die-casting is shaped, and then take the shaped die-casting out of the lower die, and finally replace the next die-casting to be shaped. This greatly reduces the working efficiency of the shaping device. In addition, some shaped die-castings are easily affected by the high temperature of the shaping device and stick to the lower die, which brings trouble to the staff's material removal work.
