Design of mould for car glass window decoration board
Aiming at the structure that both ribs and glue-reducing slots in the buckle position of the decorative plate of automobile glass windows,due to the limited space of the buckle,two inde-pendent sliding blocks could not be designed.So,a joint demoulding mechanism was designed in which the large sliding block drive the small sliding block to move.A guide block was arranged at both ends of the small slider to make it move along the slope direction of the rib position and the glue-reducing groove,and the slope of the guide block was consistent with the slope of the rib po-sition and the glue-reducing groove.When the small slider slides on the surface of the large slider,it could ensure the smoothly demoulding of rib position and the glue-reducing groove.The injec-tion moulding defects of the product surface were solved by using hot runner to cold runner.The combined inclined push structure was adopted,and reinforcing rods were set on the combined in-clined push,which effectively solved the easy breaking problem.The diagonal top structure of straight rack+diagonal rack was designed to solve the interference problem.
