Hot runner injection mold design of the fixed plate for smartphone’s motherboard based on NX
Abstract: Plastic industry is one of quickest industry classes in the world grows now, but injection mold is development quick type, therefore, the research casts the mold to understand the plastic product the production process and improves the product quality to have the very big significance. With the development of injection molding technology and the pursuit of high precision plastic products. Traditional cold runner mold has been unable to meet the demand with the pursuit of high precision plastic products. The advantage of the hot runner is that they can not only make the product more attractive, material savings, higher production efficiency, but also make the life of the mold at least 5 times longer. Process analysis of this design include parting design, mold base design, gating system design, hot runner ejection system design, water design, 2D drafting, etc, which reflects the superiority of NX / Mold Wizard module in the mold design. Through this design, may to cast the mold to have a preliminary understanding, notes in the design certain detail question, understands the mold structure and the principle of work.
