Abstract
The plastic product widely applies to profession and so on automobile, electrical appliances construction, the plastic mold development sudden appearance of a new force, the plastic mold design and the manufacture status is day by day remarkable. The plastic mold accounts for the proportion in the entire mold profession also gradually to increase, the plastic mold technology obtained the very big development.
New-style methods were adopted to design the mold of the external shell of the mobile telephone in order to get high-quality mold of mobile telephone with lower cost and shorter time.
First, introduce the types and basic structure of the mold, the relation of the mold and the injection machine, then elaborate the usual principles of mold design and some problems during design. Base on the above-mentioned theories and get united to the specific parameters and requisitions of the external shell of the mobile telephone to choose suitable injection machine, and to ascertain the parting surface, calculate the dimension of male mold and the cavity block, design the suspension mechanism, gating system, cooling system and ejecting mechanism.
Boundary element method was used to calculate these parameters: the optimum locations of the gate, filling time, filling pressure, advancing front temperature, maximum injection pressure, injection time, the location of weld mark during flow process, cooling time, temperate of cooling water, deformation size of the product and so on. Through the comparison of analogue results of three types of cooling schemes, the optimal distribution of the cooling system and the rational diameter of water pipes were ascertained.
