Design of Ejection System in Transfer Mould Tool and Justifying Material Selection of Rubber Bumper Spring Component
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2015, Vol 2, Issue 7
Abstract
There are more advanced quality and productivity requirements on rubber products. Transfer moulding remains the most popular method for producing the associated rubber parts. The main phases in a transfer moulding process involve filling, cooling and ejection. The properly determined gate location leads to better resin flow and shorter delay time, for that multi gating system is induced to bring down the defects in the component. The design of ejection system is one of the major considerations and adopting the air blow ejection by manual pneumatic switch (MPS) to achieve proper ejection of the component from the transfer mould. The material for rubber bumper spring is NR/BR (Natural/Polybutadiene) Rubber blend. Designing of mould is carried out by using computer aided designing software solid works 13.
