What is the basic features of a gravity die casting mold
Posted by Admin
A gravity casting mold is a type of openable metal mold. It has a cavity at the bottom that corresponds to a crankshaft. A pouring gate connects the lower end of the cavity to the upper part, and the molten metal flows up through this resulting cavity under gravity. The mold is then closed and the finished product is ready to use. This article will cover the basic features of a gravity casting mold and how it can help you.
A gravity casting machine cannot produce the casting product directly, and the product is not complete without a gravity-casting mold. In order to create the casting, the mold is made according to the dimensions of the finished product. A CNC milling machine carved the mold to fit the product. The mold is then placed on the worktable of a gravity casting machine. Once the mold is in place, heated molten metal is poured into it. Metals such as brass and aluminum are used, and the metal flows slowly into all corners of the mold. Once the metal is cooled, the casting blank is removed.
The main objective of the present invention is to provide a gravity-casting mold with improved features that minimize the generation of surface defects such as wrinkles. The enlarged cross-sectional area of the mold cavity reduces the flow rate of molten metal into the cavity. A heat-insulating layer is formed on the side surfaces of the increased portion of the mold's cavity. As a result, the molten metal pours into the mold cavity at a lower rate than with conventional methods.
The advantages of using a gravity-casting mold are numerous. A high-quality part produced with the process benefits from tighter tolerances and reduced machining. A gravity-casting mold also offers advantages in terms of cost-efficiency. Its cost-effectiveness is a key factor in deciding on this method for your company's casting needs. It also allows you to add additional coatings such as insulating and reflective materials for a high-quality finish.
A gravity-casting mold is a complex mechanical device that is used to inject molten metal into a hollow metal mold. It is generally made of aluminum, steel, or sand. The molten metal flows in a hollow mold, which is made of high-temperature-resistant materials. The molten metal then condenses and solidifies, forming the object into the desired shape. There are many types of molds used in the process of casting, but the one most commonly used is the sand mold.
