The Design & Research Of Two Location One Step Injection Molding Machine Which Has Eight Die Cavities For Rubber Shoes Outsole

At present,compression mold method is widely used in the production of rubber shoes outsole,it takes long time for the rubber to be heated in the mold cavity to the curing temperature,and its production efficiency is low;its locking pressure is relatively low,the sole is not dense enough,the service life is short;it need lock the mould after poured,and easily lead to waste of resources;when the molding machine have many mould cavity,the clamping force is relatively large,and the structure of the molding machine is huge.In this paper,through the design and research of the two-location one-step injection molding machine which has eight die cavities for rubber shoes outsole,the above problems are solved,and the following conclusions are obtained:1.In this paper,one-step injection technology is first used to rubber shoes outsole production.The one-step injection technique needs to be locked before injection,the tightness of sole is better,the service life is longer;no residual material is produced during injection and the material is saved;the rubber material is injected into the die cavity with a high temperature and high pressure status,which shortens the curing time and improves the production efficiency.2.In this paper,the theory of capsule expansion locking is put forward for the first time,and applies it to the mode locking system.The capsule expansion locking theory is combined with the electric screw device,the dynamic locking mode is changed into the static mode locking by using the quick opening and closing ability of the electric screw and the maximum pressure generated by the expansion of the capsule,and the structure of the machine is simplified greatly;in the process of rapid opening and closing,the linear guide rail is adopted to improve the precision of mold closing and improve the stability and reliability of the machine.3.The die system of eight die cavity with two positions is designed.One-step injection technique,which uses quantitative information,breaks through the limitation of injection capacity,and it can realize the simultaneous injection of eight cavities;and the injection method of two stations can make use of the waiting time of the injection machine in the vulcanization of the sole,it improve the production capacity greatly.4.The hydraulic motor drive is designed.And the hydraulic motor drive response time is short,small hysteresis and precise control,which solves the problems of large inertia and serious lag of all electric injection.5.The quantitative and positioning device,such as press,injection and mold locking,is combined with pressure sensor,realize the intelligent control and the forming quality is ensured,and the positioning precision is improved.6.ANSYS analysis software is used to optimize the key components,so as to improve the safety and reliability of the design.And the simulation of the movement of the mechanism is simulated by dynamic simulation software,check whether the organization interference during assembly and movement,improve the design efficiency and design level,the advantage of synchronization between modern design idea and the manufacture has fully manifested.
