Description
Technical field
The present invention relates to a kind of technical field of mold, particularly relate to a kind of oil drum blow mold.
Background technology
Oil drum, namely contains oily bucket, is generally iron sheet or plastic material makes drum. all steel drums, metal bucket, Plastic Drum, ton bucket, kilolitre bucket or other containers are all likely damaged in long-term transport, use procedure, cause leakage.Need anti-misfortune in possible trouble.These oil drums storing oil product, chemicals and hazardous chemical are placed on Sheng leakage pallet and (are also anti-leak tray, anti-overflow pallet, dish is let out in control, contains and leaks clamp etc.), contain leak platform (being also anti-overflow platform, anti-leak platform), IBC contains in leakage pallet (being also IBC anti-leak tray).Contain leak pallet, contain leak platform, anti-leak platform have firm in structure, can forklift operator, anti-skidding, the feature that can be set with, when occurring to leak, all leakage liquids will flow in the Sheng drain region of pallet or platform along pallet or platform grid automatically, can not flow to ground, corridor or passage.Contain to leak pallet and contain and leak platform and all there is drain plug, when leaking to a constant volume, can the liquid of emptying leakage.The liquid that major part is leaked can direct reuse.
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.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 existing blow mold for oil drum closure pressing speed in process is comparatively slow at present, and stability is not high, causes working (machining) efficiency low, and goods do not reach inadequate wall thickness.
