Into a period of innovation of plastic molding processing technology, compared with the early in the range of processing plastic materials, plastic injection processing plant parts of aspects such as the scope and the quality of the parts have a major breakthrough.
Innovative molding technology, not only make the past difficult forming heat sensitive and high melt viscosity of plastic raw materials and convenient become parts, but also makes the past less use of long fiber reinforced material, group that plastic and plastic sheet can be a lot as raw materials for efficient molding technology.
parts material USES reinforced pp, belongs to thermoplastic. The plastic good stiffness, water resistance, heat resistance is strong, the stage performance has nothing to do with temperature and frequency, is the ideal insulation material. Forming performance, the small plastic water imbibition, better liquidity of the melt, forming easily. The downside is shrinkage rate, easy to produce porosity, dents, deformation, etc. Molding at low temperature are prone to stress. When molding so should strictly control the molding temperature, the gating system should be relatively slow cooling.
reciprocating screw injection molding, reaction injection molding and plastic and so on one batch of plastic parts unique to the emergence of production technology, marked the plastic molding processing from the transformation, the transplantation of transition during the period of the development can play a more plastic molding manufacturability of new period of molding technology. During this period the development of processing technology, make product production process from the mechanization and automation further towards continuous, procedural and adaptive control the direction of development.
due to lateral holes and smaller lateral convex platform, core strength and assembly problem, so the slide block and side core Mosaic adopts modular structure. Slider sliding guide the integral sliding block and integral guide way, can make the mould so compact bodies, assembly is simple. Because of the side core-pulling distance is shorter, so the guide sliding length should accord with orientation in the mould when required. The slider of the positioning device in the form of the combination of spring and limit stop.
die adopts application of insert or composite structure not only processing easier and save steel material. According to in the design of supporting and fixed parts provide empirical data to determine on the fixed mould plate, the plate, the fixed plate, the dynamic model of plate thickness, according to the launch of the structure size on stroke and to determine the thickness of the block, this mould height is entirely sure down, about 190 mm. Early injection molding technology was borrowed from other material processing method, so the early processing method is mainly transplanted.
select the ideal mold structure is to determine the necessary molding equipment, under the condition of absolute reliable ideal number of cavity can make the mold itself the job satisfaction of the plastic parts processing technology and production and economic requirements. Technical requirements of the technology of plastic parts is to ensure that the geometric shapes of plastic parts, the surface roughness and the dimensional accuracy. Economy requirement is to make plastic parts of low cost, high production efficiency, mold can continuous working, long service life and save labor.
plastic molding equipment design and manufacturing technology progress, the deepening of the research and plastic forming theory, for the increase of the plastic forming technology and innovation. Mobile screw injection molding machine, the emergence of twin screw extruder, the heat sensitive and high melt viscosity of thermoplastic and thermosetting plastic can adopt efficient molding technology to produce high quality of injection molding processing parts. Reaction injection molding technology of polyurethane, epoxy resin and unsaturated polyester oligomer of liquid monomer polymerization molding.
