Modular design applied to beverage-container

injection molds

The Abstract: This work applies modular design concepts to designating beverage-container injection molds. This study aims to develop a method of controlling costs and time in relation to mold development, and also to improve product design. This investigation comprises two parts: functional-ity coding, and establishing a standard operation procedure, specifically designed for beverage-container injection mold design and manufacturing. First, the injection mold is pided into several modules, each with a specific function. Each module is further pided into several structural units possessing sub-function or sub-sub-function. Next, dimen-sions and specifications of each unit are standardized and a compatible interface is constructed linking relevant units. This work employs a cup-shaped beverage container to experimentally assess the performance of the modular design approach. The experimental results indicate that the modular design approach to manufacturing injection molds shortens development time by 36% and reduces costs by 19 23% compared with the conventional ap-proach. Meanwhile, the information on

modularity helps designers in perse products design. Additionally, the functionality code helps effectively manage and maintain products and molds.

1.Introduction

Recently, growing market competition and increasingly perse customer demand has forced competitors to increase the speed at which they deliver new products to the market. However, developing a mold for mass produc-tion requires considering numerous factors, including product geometry, dimensions, and accuracy, leading to long product development time. Introducing modular design concepts into product design appears a key mean of facilitating product development, since it increases design flexibility and shortens delivery time [1–4]. Mean-while, a high level of product modularity enhances product innovativeness, flexibility, and customer services [5].

Modularity is to subpide a complex product into modules that can be independently created and then are easily used interchangeably [6, 7]. There are three general fields where modularity could be implemented including modularity in design (MID), modularity in use (MIU), and modularity in production (MIP) [8]. MID involves stan-dardizing basic structural units which perform specific functions, thus facilitating flexible assembly of various products [9, 10]. MID can reveal product structure, namely the relationship among different products. Related products are termed product family and include both basic and specific functions. Developing product families offers benefits in terms of multi-purpose design and thus reduces production costs [11, 12]. MIU is consumer-driven decom-position of a product with a view to satisfying the ease of use and inpidually. MIP enables the factory floor to pre-combine a large number of components into modules and these modules to be assembled off-line and then brought onto the main assembly line to be incorporated into a small and simple series of tasks.

MID has been broadly applied to numerous areas and has exerted significant effects in terms of cost reduction and design persity [13, 14]. However, there is limited empirical research that has applied modular design to molds [15–18]. This study thus aims to reduce mold development time by applying modular design and develop a standard operation procedure for designing beverage-container injection molds, which are characterized by scores or even hundreds of components.

2.General procedures of designing injection molds

Basically, an injection mold set consists of two primary components, the female mold and the male mold. The molten plastic enters the cavity through a sprue in the female mold. The sprue directs the molten plastic flowing through runners and entering gates and into the cavity geometry to form the desired part. Sides of the part that appear parallel with the direction of the mold opening are typically angled slightly to ease rejection of the part from the mold. The draft angle required for mold release is primarily dependent on the depth of

the cavity and the shrinkage rate of plastic materials. The mold is usually designed so that the molded part reliably remains on the male mold when it opens. Ejector pins or ejector plate is placed in either half of the mold, which pushes the finished molded product or runner system out of a mold. The standard method of cooling is passing a coolant through a series of holes drilled through the mold plates andconnected by hoses to form a continuous pathway. The coolant absorbs heat from the mold and keeps the mold at a proper temperature to solidify the plastic at the most efficient rate. To ease maintenance and venting, cavities and cores are pided into pieces, called inserts. By substituting interchangeable inserts, one mold may make several variations of the same part.
