Design of hot runner injection mold for Desk lamp adjust bearing
Abstract: Starting from the lamp was invented, it has been provided the convenience for people. Along with the development of The Times, the lamp the user's age, living environment and different demand, the lamp from the modeling, the function is always changing. In modern life, people know more and more use of desk lamp to pursue the fashion life. And adjust the bearing is the key to adjust the lamp shade and bracket connection parts. This paper described its injection mold design process. Including parts of process analysis and die structure design, selection of formwork, pouring and cooling system design, etc., compared to other injection mold design, this article is hot runner design, including the design of the nozzle and manifold plate. In this paper, we use 3 d software UG7.5 and 2 d CAD software to complete the design.
