The core shooting machine complete sand shooting step in the foundry sand core process can be divided into three stages: before sand-blasting, free sand-blasting and sand compaction are compacted.

The pneumatic system of core shooting machine is composed of basic circuits such as fast exhaust circuits, sequence control circuits, electromagnetic commutation circuit and voltage regulation circuits. Because of adopting electromagnetic chase-pneumatic control, the system has the advantages of high automation, interlocking action, perfect safety protection and simple system.

The formation mechanism of scale in the hot core box of the sand core shooting machine is mainly due to the impact of the sand jet airflow on the surface of the core sand during the sand shooting process, part of the resin is broken, and a small amount of resin is pressed and adhered to On the surface of the core box, a layer of hard and dense hardened resin scale is gradually formed on the surface of the core box.

In sand compaction, sand flow energy and pressure difference are the two main factors of core shooting machine sand compaction. In addition, poor exhaust can also lead to poor sand core compactness. Let’s analyze these three main influencing factors and how to solve them.

The core shooting machine mold is the key structure of the core shooting machine to produce sand core products. Whether the core shooting machine can produce good quality and high-quality products, the mold plays a very important step. So, here comes the problem:

Sand leakage in the core shooting machine is a common problem. There are different solutions for sand leakage at different locations. Briefly analyze several situations:

The application of core shooter machine in casting production, the first is the best alternative tool for manual core shooting, also it is a major advancement in foundry production automation.
