Description
Technical Field
[0001] The utility model relates to the technical field of aluminum alloy die casting, in particular to an aluminum alloy die casting device. Background Art
[0002] Die casting is a metal casting process that uses high pressure to apply molten metal to the mold cavity. The mold is usually made of a stronger alloy. This process is somewhat similar to injection molding.
[0003] The traditional die-casting process generally involves pouring molten aluminum alloy liquid into the interior of a mold, cooling it into shape, and finally demolding it. The existing die-casting structure generally consists of two left and right die-casting templates forming a closed mold space. The two die-casting templates are not an integrated structure, which will result in irregular burrs on the edges of the formed product after the die-casting is completed, requiring subsequent grinding and polishing. The burrs produced on each product are inconsistent, which will increase the difficulty of subsequent grinding and polishing. Utility Model Content
[0004] The purpose of the utility model is to provide an aluminum alloy die-casting device to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aluminum alloy die-casting device, comprising a working chamber, a first die-casting template is fixedly installed at the front end of the working chamber, a liquid injection channel is installed at the front end of the first die-casting template, a groove is provided on the inner walls on both sides of the left and right sides of the working chamber, a threaded rod is rotatably connected to the inside of the left groove, one end of the threaded rod is connected to a driving motor through a rotating shaft, a second die-casting template is threadedly connected to the surface of the threaded rod, and an installation groove matching the second die-casting template is provided at the front end of the working chamber.
[0006] Preferably, a guide slide bar is installed inside the groove on the right side, and a driving structure is slidably connected to the surface of the guide slide bar, and the other end of the driving structure is connected to the second die-casting template through a rotating shaft.
[0007] Preferably, the other end of the second die-casting template is rotatably connected to a slider with a threaded hole, and the slider is threadedly connected to the threaded rod through the threaded hole.
[0008] Preferably, a feed port is provided at the upper end of the injection channel, and a hydraulic push rod is slidably connected inside the injection channel, and the hydraulic push rod is connected to an external supporting structure.
[0009] Preferably, a heat preservation structure is installed outside the injection channel, and the heat preservation structure includes a heating chamber and a partition chamber. A layer of heating chamber is installed outside the injection channel, and a partition chamber is installed between the heating chamber and the injection channel.
[0010] Preferably, the lower end of the working chamber is an opening, and a demoulding structure is provided at the lower end of the working chamber.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The aluminum alloy die-casting device fixes the first die-casting template at the front end of the working chamber. When die-casting is required, the threaded rod is driven by a driving motor to rotate, and the second die-casting template is driven to enter the interior of the installation groove. At this time, the second die-casting template is fitted with the first die-casting template, and the aluminum alloy liquid is injected into the cavity between the second die-casting template and the first die-casting template through the injection channel. The aluminum alloy liquid is shaped by pressurized cooling, and then the second die-casting template is driven by the threaded rod and the driving motor to separate from the first die-casting template, and the die-cast product is taken out. The movable second die-casting template is set to cooperate with the installation groove for installation. During the die-casting process, the aluminum alloy liquid is difficult to separate from the space of the installation groove, and the burrs formed on the die-cast product will be limited to the interior of the installation groove, which saves a certain degree of time cost for subsequent grinding and polishing of the burrs.
[0013] 2. The aluminum alloy die-casting device is provided with a driving structure. After the second die-casting template leaves the installation groove, the driving structure drives the rotating shaft and the second die-casting template to rotate downward vertically. At this time, the die-cast product is taken out by the mechanical arm, which can be more easy and convenient with the help of gravity. BRIEF DESCRIPTION OF THE DRAWINGS
