Abstract

The mold industry is expanding due to the continuous advancement of materials science, leading to a wider variety and increased prevalence of mold products. The paper initially examines the principles of injection molding for molds before proceeding with the design of the mold structure. This includes completing the design for the mold's injection system and gate; determining working dimensions and calculating forming part specifications; selecting standard parts for the mold frame; designing guiding mechanisms for closing the mold as well as positioning systems; and developing a heating system. Additionally described is how Solid works and CAD were used to create part drawings and assembly diagrams. Finally, an analysis on overall feasibility of the mold is conducted along with summarizing the entire article while looking ahead to future prospects. This design presents a structural plan for an injection mold intended for plastic pen holders that caters to personalized needs in daily life situations.
