Overall slope mold engineering requirements are: adhere fully implement the scientific concept of development, taking a new road to industrialization, the integration of two of the depth on the promotion of industrial economic transformation and upgrading, innovation and the development of a strategic position to lead the enterprise information integration innovation, agile manufacturing , green manufacturing, mold slope enhance independent innovation competitive advantage. To leading enterprises, promote research and technological breakthroughs key core technology to create high-end industrial value chain; relying on industry clusters to build information service platform, innovative business services, and vigorously promote the integration of the two processes of SMEs. Enterprise design digital, intelligent equipment, production automation, network management, e-commerce, service customization, "six" linkage, rising slope mold core competitiveness, promote enterprise-demand, lean manufacturing, green manufacturing smart and sustainable development. Slope mold is made using raw materials engineering polypropylene resin molding good liquidity. A melt flow rate in the 1-10g / 10min range. Use high-pressure injection molding, material temperature uniformity, fill rate, dwell fully. Should not use direct gate to prevent uneven shrinkage, internal stress increases. Due to mold shrinkage, low rigidity, making it difficult to ensure dimensional accuracy. Slope in the mold cooling time should be long enough. Most good gloss, easy to produce due to uneven shrinkage marks and shine, so be careful designs. With cylinder temperature and mold temperature of different slope, slope mold products look and size will be different, so keep a certain temperature molding, and this is very important. Slope mold, plastic mold slope revetment is mainly used for the production of bricks using high-speed, rail, water, dams, etc., in order to prevent soil erosion effect. Slope is the automated injection plastic mold injection molding apparatus, injection molding is a plastic particles are added to the quantity of the injection machine barrel, the barrel is rotated shearing friction heat, generated by the screw and the plastic particles gradually melt into the flow state, then in pushing the plunger or a screw, the molten plastic to a high pressure and a relatively high speed through the nozzle is injected into the lower cavity of the closed mold. Due to the cooling effect of the mold, the mold cavity gradually solidified molten plastic and stereotypes, and finally remove mold mold slope. Can be summarized as: feeding - plastic melt - injection - Cooling stereotypes - plastic mold. Plastic mold slope polymer resin used is oil or gas as raw material, obtained by the synthesis reaction. The so-called polymer resin refers to monomeric compound through a polymerization reaction, the polymerization synthetic polymer polymer having a molecular weight up to thousands or even millions. In the field of classification of polymer relative molecular mass of low molecular weight less than 1000 persons become, who said between 1000-10000 whichever polymer or oligomer, or more than 10,000 known as polymer. We generally do slope mold plastic used, the relative molecular mass of approximately between 10000-1000000, and the relative molecular mass of less than 10,000, the oligomers used to do textile resins, coatings, synthetic resin. So we produce mold slope has high density, toughness, not easy to deformation, long life and other advantages.
