Core-making machine Core-making machine core-making machine Core-making machine core-making machine Casting equipment used to make cores. According to the different methods of real sand during core making, core shooting machines and core making machines can be divided into shock core making machines, core extrusion machines and core shooting machines. The vibrating core making machine is used to produce large and medium-sized sand cores that are hardened outside the core box, and can also be used for no-bake sand cores that are hardened inside the core box. It compacts the core sand by shock action. The core extrusion machine is used for sand cores with constant cross-sectional shape. The core shooter is a core-making equipment developed in the 1950s (Figure 1). The working principle of the core shooting machine is shown in Figure 2. When shooting sand, the compressed air quickly enters the sand shooting cylinder, pushes the sand particles through the gaps in the sand layer, and forms a sand air flow, so that the core sand is injected into the core box at high speed, and the core box is filled at the same time. Tight. The size of the core made by the core shooter, the surface is smooth.

According to the shape and size of the core and the binder used in the core sand, the core shooting machine is divided into: ①The hot core box core shooting machine is a small and medium-sized core making machine with thermosetting resin as the binder. Heat hardens the core. ②The shell core machine is used to manufacture thin shell cores. The sand surface of the core sand is pre-covered with a phenolic resin film, which is hardened in a heated core box. ③The cold box core shooter is a small and medium-sized core making machine with resin as the binder, blowing air into the cold core box to harden the core. ④ Ordinary core shooters use vibrating sand buckets to add sand to make cores hardened outside the core box. Coated sand core shooting machine solves the problem of labor shortage in foundries flexible. The driving method of the coated sand core shooting machine is pneumatic, and it is used in conjunction with an air compressor. Equipped with mold cleaning and coating device.

The machine is easy to operate and easy to use, even a lesbian can easily operate it. Equipped with a pneumatic sand feeding device, which can automatically add sand quantitatively. Thereby greatly reducing the labor intensity of workers. Special specifications can be designed and manufactured according to the needs of users. It can also design supporting designs and make molds for users. The advent of the coated sand core shooting machine has led to manual core making, and a part of it can also be made into a sand-coated shell casting method, which reduces the occupied area of the casting workshop, and how many layers can be stacked together. Simple, convenient, high utilization rate of molten iron. At the same time, the coated sand core shooting machine also solves the problem of labor shortage in most foundries. >Core shooter adopts '>coated sand core shooter, vertical parting, Beijing core shooter, suitable for hot core box, automatic and manual dual control mode, can be automatic or manual, convenient and flexible. The driving method of this model is pneumatic, and it is used in conjunction with an air compressor. Equipped with mold cleaning and coating device. The machine is easy to operate and easy to use, even a lesbian can easily operate it. Equipped with a pneumatic sand feeding device, which can automatically add sand quantitatively. Thereby greatly reducing the labor intensity of workers. Special specifications can be designed and manufactured according to the needs of users. It can design and make molds for users.
