Power Tools Die Casting Part Factory Introduces How The Parting


    Aluminum alloy die castings are common pressure castings. The aluminum and aluminum alloy heated to the liquid state are cast to the material port with a die casting machine, and the parts are manufactured by the die casting machine. After die-casting, the aluminum alloy die-casting parts can be made into various complicated shapes, and have high precision and smoothness, which can not only save electricity and metal materials, but also save bad labor costs. Today, Power Tools Power Tools Die Casting Part  Factory will introduce how to choose parting surface for aluminum die casting?

    According to the shape of the parting surface, the parting surface of the die-casting mold can be divided into four types: straight, inclined, stepped and curved. The direct parting surface is simple in structure, convenient to manufacture and widely used. For the stepped parting surface, a gating system is generally installed on one of the stepped surfaces, and an overflow system is installed on the other stepped surface to facilitate the filling and discharging of molten metal.

    Many factors need to be considered when determining the parting surface. Therefore, in the selection of the parting surface, in addition to the structural characteristics of aluminum alloy die castings and the arrangement of the gating system. The processing technology and assembly technology of aluminum alloy die-casting molds and the demolding conditions of die-casting parts should be considered and determined. The principles for determining the parting surface are:

    1. The casting must stay in the movable mold when opening the mold and be easy to take out from the mold cavity.

    2. Parts with different shaft degrees and high dimensional accuracy requirements should be placed in the same mold half as much as possible.

    3. The parting surface is generally not set on the surface with high quality requirements.

    4. The setting of the parting surface should be conducive to the setting of the pouring system, eliminate burrs, flashes, gates, etc., and be conducive to painting

    5. The setting of the parting surface should try to simplify the structure of aluminum alloy die castings, and fully consider the casting performance of the alloy.
