toy horse active gears mold design

As the synthetic polymer materials with good plasticity, plastic has been widely used in computers, mobile phones, automobiles, home appliances, and toys products manufacturing, which suggests that the development of plastic mold bears a broad market space. The designed parts of this time are toy horse active gears, with the characteristics of light weight, high strength, easy to clean, as mass production products. Based on the basic principles of plastic molding, especially the working principles of the injection mould with single parting surface, this paper completes the design of injection mould of the active gears, using the basic methods of designing and manufacturing with computers’ assistance. The set of moulds adopts the structure of a mold with four cavities and a mold of two-open and three-plate with a feed point gate model. Meanwhile through the structural process analysis of the plastic parts, this paper also points to fix the mold parting surface, the number of cavity, the form of the runner and design the major components of molds like the demolding mechanism, the whole mold steering mechanism, cooling system and the ready molded parts. And the complete mold assembling graph and the main parts graph are drawn through the
