Abstract :

Injection molding is one of the growing molding process in the plastic field. It is a cyclic process of forming plastic into a desired shape by forcing the material under pressure into a cavity. The shaping is achieved by cooling (thermoplastics) or by a chemical reaction (thermosets). It is one of the most common and versatile operations for mass production of complex plastics parts with excellent dimensional tolerance. It requires minimal or no finishing or assembly operations. In addition to thermoplastics and thermosets, the process is being extended to materials such as fibers, ceramics, and powdered metals, with polymers as binders. Molds basically consist of core and cavity plate, core and cavity back plate, ejector plate, stripper plate, sprue, gates etc. Injection molding is preferred where tight tolerance, good quality and high rate productions are required. This paper presents the design of a plastic injection mould for Air filter box bottom cover. The technique, theory, methods as well as consideration needed in designing of plastic injection mould are presented. Design of mould is carried out using wildfire Pro-E 3.0. Poly Propylene talc filled [PPTF] was used for production of this component. The tool was designed to produce a good quality component considering the ease of manufacturability, assembly and Positive ejection of the component by optimizing time and cost. Component requires two side cores. Hydraulic actuation was used in the tool construction. Tool design and development is a specialized and critical area. The tool design should match the machine specification and should be accurate and economical for successful life of a component or product.
