【Abstract】In order to improve injection efficiency and material utilization of connecting rod components, hot runner technology is introduced. Design process includes plastic part analysis, mold design and assembly drawing design. It mainly introduces determination of design plan, selection of mold base and selection of hot runner system. Design process adopts UG full 3D design, which helps to make mold structure intuitive, to find problems and avoid unnecessary errors. 1 Introduction Hot runner injection molding is an important development direction of traditional injection molding. Its biggest feature is that plastic in runner system will not solidify during production process, nor will it be removed from mold with plastic part. Simply put, nozzle of injection molding machine is directly extended to plastic part for waste-free production, thereby greatly improving material utilization rate; at the same time, process is shortened and production efficiency is improved. In mold design p...

Compared with ordinary flow channel molds,  hot runner mould  have significant advantages such as saving time and materials, high efficiency, and stable quality. However, its wide application has been affected by their failure in use. With technological advancement of mold industry, hot runner mould has made great progress in flow channel melt temperature control, structural reliability, hot runner component design and manufacture, which makes hot runner technology regain people's attention and favor. First, residue at the gate is protruding or flowing, and surface appearance is poor. Main reason Gate structure selection is unreasonable, temperature control is improper, and there is a large residual pressure in the melt of flow channel after injection. Solution 1)  Improvement of gate structure . Usually length of gate is too long, which will leave a long gate material on the surface of plastic part. If...
