After Chinas accession to the WTO, the ability to attract foreign investment is increasing year by year, become the world products manufacturing factory position even more prominent, and the injection mold also in the meantime plays more and more important role. Plastic as one of the basic materials of the development of the modern society and economy, is indispensable to the agriculture, industry, energy, transportation and other areas of the economy, an important material, its use has penetrated into all areas of economic and social life, and iron and steel, wood, cement, become the four pillars in the field of materials. Mold is the foundation of industrial production technology and equipment, various industries are widely used in the production of the final product, its value is often to mold their own value of dozens of times, hundreds of times, was hailed as the benefit amplifier. The level of mould production technology, has become an important symbol to measure the level of the manufacturing area.The design for the toothbrush cup mold design and manufacture, it system introd
