mould paper
1.Based on the heat expansion characteristic of glass and its affecting factors, and thinking about the heat expansion characteristic of metallic material of mould,in this paper the precision calculating formula of the forming sizes of cavity and core of glass cavity mould is proposed, that is important for the design calculation of cavity mould of glass product which sizes demand more precise.
3.Abstract: Guiding accuracy of casting mould depends on structure and oscillation parameters,such as elastic deformation of guiding leaf-springs,play of bearings between linkages,stroke and frequency of mould oscillation,etc..In this paper,these factors are studied by means of kinetic and dynamic analysis of oscillating mechanism.
4.The Organizing Committee will send 50000 letters of invitation and 100000 tickets to national manufacturers, distributors, agents, high-grade purchasers, terminal users and scientific research institute, design institute and professional association, etc. in the relevant industrial fields of machinery, chemicals, electronics, electric appliance, metallurgy, forging, ship, communications, household appliance, building materials, auto, motorcar, plastics, packaging, medical treatment, mould, aviation and space flight, paper making, textile, environmental protection, water conservancy, electric power and agriculture, etc.
5.Mould design and manufacturing are critical technologies in RTM process, this paper mainly investigates the principal of mould design, the requirements of mould material, elemental computing methods, the theory of resin flow and some structural design such as the location of in jects and vents, clamping mechanism, seal and guiding mechanism etc. , it also provides some relevant design data.
6.This paper introduces the Pro/Engineer-based CAD/CAM technology of injection mould including mould designing system,work flow of mould design and BNC mould processing,and demonstrates through examples the powerful functions and high integration of Pro/Engineer in injection mould design and making.
7.In this paper, the effects of the thermo-field distribution and mould temperature distribution on the growing of the cast polycrystalline silicon are discussed. The paper discribes some electrical characteristics of the solar cell made from the cast polycrystalline silicon. Results indicate that the highest efficiency of the solar cell made from the ingot is 11.9%(AM1.5).
