The invention discloses a mould applied to the field of casting. The mould comprises a lower mould, an upper mould, a lower mould sprue gate and an upper mould sprue gate, wherein the lower mould sprue gate is positioned on the lower mould; the upper mould sprue gate is positioned on the upper mould; a sunk chamber is formed in the lower mould; the upper mould comprises an outer frame and a module which is detachably inserted into the outer frame; the module comprises a first body which is arranged in the outer frame and has a size matched with that of the inner wall of the outer frame, and a second body which has a size greater than that of the first body and is positioned outside the outer frame; and convex or concave patterns are formed on the bottom surface of the first body. For products with the same peripheral shape and different patterns on the products, different modules of the upper mould of the casting mould are manufactured in the process of opening the mould during production according to the different products, a whole set of mould is not required to be opened, the same lower mould and the same outer frame of the upper mould are used during the production, and a production effect can be achieved by changing the different modules of the upper mould, so that the time, the labor and the materials are saved, and the cost is greatly lowered.
Description
technical field [0001] The invention relates to a casting mold. Background technique [0002] Investment casting is a casting process with little or no cutting. It is an excellent technology in the foundry industry and has a wide range of applications. It is not only suitable for casting of various types and alloys, but also produces castings with higher dimensional accuracy and surface quality than other casting methods, and even complex, high temperature resistant and difficult to process castings that are difficult to cast by other casting methods. All can be cast by investment casting. Therefore, this advanced precision casting process is widely used in manufacturing industries such as aviation, automobiles, machine tools, ships, internal combustion engines, gas turbines, telecommunication instruments, weapons, medical equipment and knives, and is also used in the manufacture of arts and crafts. Casting molds are important technological equipment used to make investmen...
