ELECTRO MAGNETIC MOULDING -MECHANICAL PROJECT

抽象的

Moulding die is a manufacturing process, which is used directly or indirectly in almost every industry. It is a primary manufacturing process and has its effect on the properties of the resultant product. In this era there is a demand to innovate processes, which can reduce lead-time, reduce cost of production without compromising with the quality of the products and reduce ill effects on environment. Electro Magnetic mould die is an innovative process having a great potential to replace conventional moulding die methods due to various advantages associated with it. This setup includes winding of copper wire such that it behaves like a solenoid with hollow cavity in which actual moulding die process is to be carried out. The setup was prepared with copper wire and winding is done until required magnetic field is created. The prepared setup and trial runs shows that there is a scope of creation of similar setup at large scale so that can be used at industrial level to utilize its advantages of reduced cost, reduced lead-time, reduced effect on environment and imparting improved properties to the resultant product.

介绍

成型模具是可以以多种方式进行的制造过程。用于模塑模具的方法的类型对所得产品的表面光洁度，微观结构，硬度，韧性等的性质具有效果。在现代行业中，有许多因素，这影响了选择要使用的成型模具过程的决定。这包括铸造产品的性质，制造，延期时间和过程的环境影响所产生的成本。磁性模具是电磁模具的应用到模塑模具的过程中。钢射击构成通过在它们上施加磁场而形成的模具。磁磁粘接在钢镜头磁键之间的应用，使模具强度。这减少了夯实过程中经过的时间。而且，通过使用磁场，破碎模具变得更容易，因为需要关闭电源以逆转磁场和模具断裂。该方法采用单件模具和EPS（可膨胀聚苯乙烯）图案，其赋予铸造产品不含与关节线相关的缺陷的优点。 Also the products have better dimensional tolerances than the products obtained from conventional methods. The amount of machining required is less thus reducing the time and cost involved in finishing a product for use. The mechanical properties like tensile strength, impact strength and hardness of the products cast from this have higher values as compared to sand moulding die products. The reason behind this improved might be the higher solidification rate of steel mould as its thermal conductivity is more than the sand mould.

EXPERIMENTAL PROCEDURE

Initially parameters for MMC are decided. First step is to select a design of magnetic setup and to define parameters like gauge of copper wire, intensity of field required, size of steel shots, composition of steel shots, size of expendable polystyrene pattern and refractory coating on its surface. The following steps are followed to perform magnetic mould casting:

A hollow cylindrical box of aluminums is used to wind the coils over it. Copper wire is used. copper coil is used for coiling. An iron box is inserted into the mould box to form the core for magnetic field. For supply to the copper coil, a power rectifier in series to battery is connected. DC supply is given to the copper coils.

钢射击填充在模具盒中，然后将图案保持在中心，钢射击保持倾倒。倾倒钢射击到浇筑盆地的水平。在围绕钢拍供应中的图案沉降后，接通，磁场施加在钢射线上。由于磁力，这些钢射击彼此束缚，因此形成包括围绕图案的钢射击的模具。通过提高电压，增加模具强度，可以增加场强。只有使用Autotransformer直到一定限度，可以增加电压，因为更高的电压值可能导致线圈的燃烧。

ADVANTAGES

Magnetic moulding, is an innovative process and it is an expendable model and it is used that is surrounded by metallic particles bonded together by the action of an induced magnetic field.
In that magnetic moulding process have the advantages of the lost foam process and the permanent mould processes.
The benefits of magnetic moulding one precision magnetic moulding can replace a sub-assembly.
磁性成型工艺以非常竞争力的成本生产高质量和复杂的部件。
