Automatic foundry sand molding machine is one kind of foundry equipment used to make sand molds, the sand molding machine working process: automatic shooting the loose molding sand into the sandbox, automatic compaction, automatic mold lifting, automatic box closing, manual sand core placement, automatic mold pushing, etc. after casting, the sandbox is pushed to the sand mixer, which can be produced continuously.
The core shooting machines are divided into hot core box core shooting machines and cold core box core shooting machines according to the molding and curing methods of sand core products. Do you know the difference between them and what are their respective applications? Next, this article will reveal to you.
The coated sand casting process has a long history of use in the casting field. Many companies use the coated sand casting process to produce a large number of castings. However, the use of coated sand casting to produce precision steel castings also has its characteristics and some shortcomings, which deserves our deep consideration.
The core shooter is the main foundry machinery for manufacturing sand cores and other castings products. So what factors affect the working effect of the core shooting machine, the causes, and how to solve it, this article will reveal to you.
Coated sand is one of the sand core raw materials of the core shooting machine. What is the use of coated sand problem, what are the main reasons, and how to solve the coated sand problem defects? This article will reveal the answers one by one.
There are two types of sand core raw material for core shooters, namely coated sand and resin sand. A core shooting machine is a common machine in the casting industry. If you want the core sand machine to produce a high-yield sand core, you need not only a good core shooting machine, but also good sand core raw materials to make the sand core.
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.
After using the core shooting machine for a long time, there will be some minor faults. The most frequent problem is the insufficient sand shooting of core shooting machine. The sand core structure produced in this way is not tight enough, and the cast workpiece will also have deformation and sand holes. So today Delin Machinery will come to solve this problem for everyone.
