5. Core casting machine, used for making core casting equipment. According to the different methods of core sand, the core making machine can be divided into shock type core making machine, core extruding machine and core shooting machine and so on. 6. Molding machine is used to make sand casting equipment. Its main functions are: filling sand, filling loose sand into sand box and compacting molding sand. 7. The pouring machine is a channel in which the liquid metal is introduced into the casting cavity. Including: sprue cup, sprue, cross runner, inner runner.
3. A casting machine that uses sand and casting to separate sand and castings from the mold by vibration and shock. The vibration source of the shakeout machine is divided into mechanical, electromagnetic and pneumatic. 4. Shot blasting machine uses shot blasting machine to throw out high speed bullet to clean or strengthen casting surface casting equipment. The shot blasting machine also eliminates the sand, eliminates the core and clean up the casting.
Casting machinery and equipment are generally classified according to the molding method. They are customarily divided into ordinary sand casting and special casting. Common sand casting includes three categories: wet sand mold, dry sand mold and chemical hardening sand casting process. Special casting of different materials according to the model, it can be divided into two categories: one with natural mineral sand as the main materials, such as casting, shell casting, vacuum casting, mud casting, mold casting, ceramic mold casting; a kind of metal as the main casting materials, such as metal type casting, centrifugal casting, continuous casting, pressure casting, low pressure casting etc.. 1. A device for pressing pieces of casting material. After the material is pressed, the utility model is convenient for storage and transportation and reduces the loss of transportation and smelting in the process of recovery and reuse. 2. Sand mixing machine, used for mixing molding sand or core sand casting equipment. Mixing machine generally has the following functions: the old sand, new sand, molding sand, adhesive and auxiliary materials mixed evenly.
