    Introduction to the working principle of shell core machine

    • The shell core machine belongs to a kind of core shooter in which the template can be turned over. A 180 ° turning function is added to the principle of the core shooter, which can pour out the uncured sand inside the sand mold and reuse it, which can save the cost of coated sand. The specific working principle is as follows. Let's have a look.

    • The shell core machine is a four-column open and closed structure, fully automatic and semi-automatic hot-core box equipment, which is applicable to various sand cores, foundry and workshop equipment for manufacturing resin sand cores. It uses compressed air to spray core sand into the inner cavity of the mold through the sand bucket, and the core sand is solidified by heating. Its working principle is to take dry resin sand into the heated core box to harden and take it out, so as to obtain the sand core with smooth surface and accurate size. Let's take a closer look at its advantages.

    • Core shooters are widely used in the casting machinery industry. The core manufactured by the core shooter has accurate size and smooth surface. However, if the operating procedures of the core shooter are not standardized, there will be hidden dangers in the mechanical production. Now let's understand the operating procedures of the core shooter.

    How to repair the defective parts of the shell core machine?

    The shell core machine is a kind of equipment that uses the hot core box technology to make the coated sand shell core. Its working process is completed at the same time as sand filling and compaction, and it is immediately hardened in the hot core box, reducing labor intensity, flexible, portable and easy to master. With electric heating, the temperature can be automatically controlled, and the workplace is easy to keep clean, creating conditions for the mechanization and automation of the core making process. The production cycle of sand cores for casting is only 10 to tens of seconds. The size and surface of the core manufactured by the core shooter are smooth. Now shell and core machines are widely used in the casting machinery industry.

    Do you know what to pay attention to when using the core shooter?

    The core shooter is a machine that uses compressed air to evenly inject molding sand into the sand box for pre-compaction, and then applies pressure for compaction. Commonly used are vertical parting boxless injection molding machine and horizontal parting boxless injection molding machine. There are some things that need attention when using the core shooter. Let's take a look at it. I hope you can pay attention to it when using it.
