RT... What are the forming methods of plastic forming dies? Which expert answers, thank you very much...
3, plastic plastic mold: a plastic board sheet material forming a mold of some simple plastic products, its principle is to use vacuum or compressed air bloom forming method in the fixed die or punch on the plastic plate, sheet, and paste in the mold cavity on the necessary molding product deformation heating softening in the case of some aspects, mainly for daily necessities, toys, food packaging products production. Because the molding mould pressure is lower, the mould material is made of cast aluminium or non-metal material, the structure is simple.4, plastic wire drawing die: it is used to a mold for production of plastic wire, its principle is through the molten plastic extruder through a pore on the mold after cooling, drawing, drawing to form the final products rolling process. The material of the mould is mostly made of cold mould steel or nitrided steel, and the structure is simple.
2, plastic blow molding die: it is used for molding plastic containerslike hollow products (such as beverage bottles, cosmetic supplies all kinds of packaging containers) of a mold molding process in the form of the main principle of extrusion blow molding, injection molding process in the form of the main principle of extrusion blow molding, injection molding, blow molding hollow injection stretch blow molding (commonly known as "injection blowing"), multi-layer blow molding, sheet blow molding etc.. The corresponding equipment for blow molding of hollow products is usually called plastic blow molding machine. Blow molding is only suitable for the production of hot plastic products. Blow molding structure is relatively simple, more materials used, more carbon is manufactured.
1, plastic injection mold: it is thermoplastic plastic products the most universal of a mold used in the production and processing equipment for plastic injection molding is the corresponding processing equipment for plastic injection mold is the corresponding plastic injection molding machine, plastic injection machine in the first floor heating cylinder heated melting, and then in the injection machine screw or plunger driven by the gating system of injection machine and mold nozzle into the mold cavity plastic molding cooling sclerosis strippingget products. The structure is usually composed of molding parts, gating system, guiding parts, pushing out mechanism, temperature regulating system, exhaust system and supporting parts. The material is usually made of plastic mould steel, and the common materials are carbon structural steel, carbon tool steel, alloy tool steel, high speed steel and so on. Injection molding processing usually apply only to thermal plastic products production, with production of injection molding of plastic products is very wide, from the daily necessities of life to all kinds of complicated machinery, electrical appliances, transport and other parts are used injection molding die, it is a kind of processing method is most widely used in the production of plastic products.
