Description
技术领域 technical field

背景技术 Background technique
砂型铸造是一种在砂型中生产铸件的铸造方法。钢、铁和大多数有色合金铸件都可用砂型铸造方法获得。由于砂型铸造所用的造型材料价廉易得，铸型制造简便，对铸件的单件生产、成批生产和大量生产均能适应，长期以来，一直是铸造生产中的基本工艺。铸造系统一般由浇注系统及型模组成，浇注系统的内部设有冒口结构，冒口是为避免铸件出现缺陷而附加在铸件上方或侧面的补充部分，在铸型中，冒口的型腔是存贮液态金属的容器，其功能是多方面的，功能不同的冒口，其形式、大小和开设位置均不相同；浇注系统与型模之间通过浇口连接，现有的曲轴铸造成型工艺中如图6，浇注系统的浇口包括两个，浇口连接在长条状的型模的一端，两个浇口分别连接在两横浇道上，横浇道分别与直浇道连接，铸造成型时，将液态金属注入直浇道，经两横浇道分别流入浇口，并经浇口注入型模，该种浇注系统的浇道流径过长，浇道的不同部位温差大，导致金属的流动性差，浇注效果差，生产成本高。 Sand casting is a casting method that produces castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. The casting system is generally composed of a gating system and a mold. The inside of the gating system is provided with a riser structure. The riser is a supplementary part added to the top or side of the casting to avoid defects in the casting. In the casting mold, the cavity of the riser It is a container for storing liquid metal , and its functions are multifaceted. Risers with different functions have different forms, sizes and opening positions; the gating system and the mold are connected through the gate, and the existing crankshaft is cast and formed In the process, as shown in Figure 6, the gating system includes two gates, the gates are connected to one end of the strip-shaped mold, and the two gates are respectively connected to the two runners, and the runners are respectively connected to the sprue. When casting, the liquid metal is injected into the sprue, flows into the gate through the two horizontal runners, and is injected into the mold through the gate. The runner flow path of this type of gating system is too long, and the temperature difference between different parts of the runner is large. As a result, the fluidity of the metal is poor, the pouring effect is poor, and the production cost is high.
