Description
Technical field
The utility model relates to a kind of die apparatus technical field, particularly relates to a kind of circular pail pack blow mold.
Background technology
Blowing also claims hollow blow molding, and one develops plastic working method rapidly.Blow molding process during World War II, starts for the production of low density polyethylene (LDPE) bottle.In the later stage fifties, along with the birth of high density polyethylene (HDPE) and the development of blow molding machine, blow molding technology is widely applied.The volume of hollow container can reach thousands of liter, and some production have employed computer and controlled.The plastics being applicable to blowing have polyethylene, polyvinyl chloride, polypropylene, polyester etc., and the hollow container of gained is widely used as industrial packaging container.According to parison preparation method, blowing can be divided into extrusion-blown modling and injection-blow molding, and what new development was got up has multilayer blow moulding and stretch-blow.
Thermoplastic resin, through the tubular plastic parison extruded or injection moulding obtains, while hot (or being heated to soft state), is placed in split cavity, in parison, compressed air is passed into immediately after mold closing, make plastic parison inflation and be close on mould inner wall, through cooling and demolding, namely obtaining various hollow product.The manufacturing process of inflation film is quite similar with hollow product blowing in principle, but it does not use mould, from the angle of plastic processing technology classification, during the moulding process of inflation film is usually listed in and extruded.Blow molding process during World War II, starts for the production of low density polyethylene (LDPE) bottle.In the later stage fifties, along with the birth of high density polyethylene (HDPE) and the development of blow molding machine, blow molding technology is widely applied.The volume of hollow container can reach thousands of liter, and some production have employed computer and controlled.The plastics being applicable to blowing have polyethylene, polyvinyl chloride, polypropylene, polyester etc., and the hollow container of gained is widely used as industrial packaging container.
Extrusion-blown modling is a kind of method manufacturing hollow thermoplastic's product.The blowing object be widely known by the people has the container of bottle, bucket, tank, case and all packaged foods, beverage, cosmetics, medicine and commodity.Large blow-molded container is generally used in the packaging of chemical products, lubricant and bulk material.Other blow-molded article also has ball, bellows and toy.For auto manufacturing, fuel tank, car damper, backrest, center rest and handrail and headrest cover layer are all blowing.For machinery and furniture manufacturing industry, blow molding part has shell, door frame, frame processed, terrine or to the chamber having an open surface.It is high density polyethylene (HDPE) that plastic raw materials is squeezed in prevailing blowing, and most of milk bottle uses this polymer to make.Other polyolefin are also processed usually through blowing.According to purposes, styrene polymer, polyvinyl chloride, polyester, polyurethane, Merlon and other thermoplastics also can be used for blowing.Nearest engineering plastics are widely accepted in automobile industry.Material selec-tion with mechanical strength, weatherability, electric property, optical property and other performances for foundation.
The standby a kind of process being defined through melt mixed and polymer or polymeric system are upgraded of polymer mixture.Mixture process mixes training from join multiple additives process, polymer alloy and the reactivity of single additive, and its scope is very wide.According to estimates, the polymer production of the U.S. 1/3rd will through mixture.Mixed ingredients can customize according to the performance requirement of final application.Compounded product has the performance of hybridization, such as high glaze and excellent impact strength, or precision moding and good rigidity.The polymer that mixture is good is used for processing further by pelletizing usually.But industrial more and more to come interested be mixture combined with next step process, such as section bar extrusion, can avoid heated polymerizable thing again like this.People use various types of melt compounding equipment, from roll mill and batch blender to singe screw and Bitruder.Continuous mixture is the most frequently used equipment to (extruding machine), because he can provide the product of uniform quality, and can reduce operating cost.Have two kinds of mixed types: distributed melange material in mixed ingredients without the need to adopting shearing force just can distribute equably.This kind of mixed liquor is called as extensibility mixing or laminarity mixing.
Distributing mixing also known as powerful mixing, wherein apply shearing force smash in the solid of the group of being polymerized to.Such as when additive group is broken, actual particle size has just diminished.Compounding Operation often needs two kinds of mixed types in a procedure.General commonly people's articles for daily use are such as: bottle, jar, articles for babies, sports goods etc. the at present existing blow mold working (machining) efficiency for circular pail pack is low, and use inconvenience, quality of item is general.
