Due to water bottle cap mould production usually need large quality,size is small and complicated in internal structure,muti-cavity with hot runner for caps mould is best solution.After mould flow analysis for muti-cavity cap mould-32 cavity ,every cavity with 1 point hot runner into top of cap is the best way.
Consider for easy machining, the water caps mould manifold planning to make 2 plate.The top one is H shape,the second plate divide into 4 pieces, every pieces of plate will have 8 point of runner gate. Point gate will be use for this 32 cavity cap mould, point gate have good function for keep pressure,reduce stress and cost will be less compare to valve gate.
unscrewing cap mould structure are better then screwing cap mould, But the demolding system for unscrewing cap mould still very important. After know the basic feature of caps, the screwing inside the cap will ejector directly. Core side will be design as insert, separate for 3 parts: Screwing core, water proof ring core and ejector core.
