Features of Ram Mould Design
Ram moulds are a type of mould widely used to form complicated shapes in metal industry. It is an advanced die-casting tool widely used in metal casting processes. Ram moulds are designed for die-casting applications and feature a metal slug that slides in a cavity of a pre-determined shape. During the metal casting process, metal slug moves through the cavity, passes through the ejection channels and is pressed by the ram which often departs out of the electric explosions.
The ram mould design features must be taken into account while manufacturing the mould. The ram mould is a complex piece of equipment that requires precise design and manufacturing. There are several crucial factors that must be accounted for in order to ensure the smooth functioning of the die-casting system. Firstly, the material used for the ram mould should be strong enough to withstand the force of the metal slug passing through the cavity. It should also have a low coefficient of friction so that it can slide with minimal resistance. Secondly, the ejector pins should be carefully considered while designing the mould. These components are used to push the molten metal out of the mould once it has cooled and solidified. The number and position of these pins are integral aspects of the design and must be carefully considered based on the complexity of the final shape of the part being cast.
The design of the ram mould should also take into account the nature of the material being cast. Different material have different melting and solidification temperatures, so the neat design should be created in such a way that these temperatures are taken into consideration both during the casting process and during ejection. Thirdly, the ram mould design should ensure that the molten metal is evenly distributed into the cavities. To do this, the mould has to be sectioned, usually into four parts, so that the metal can penetrate each part of the mould cavity.
Finally, during the manufacture of the moulds, the shape of the cavity and the amount of air that is removed from the cavity during the cooling process should be considered. The shape of the cavity is extremely important as this affects the accuracy and consistency of the final shape of the part. If a computer-aided design (CAD) tool is used, the design accuracy of the mould can be improved significantly.
In summary, there are many features to consider when designing a ram mould. The mould must be designed with the appropriate materials, number of ejector pins, cavity shape and the amount of air that needs to be removed from the cavity during cooling. Using a CAD tool can improve the accuracy of the mould and ensure the consistency of the final shape of the part.
