Description
Technical field
The present invention relates to a kind of technical field of mold, more particularly to a kind of oil drum blow mold.
Background technology
Oil drum, that is, contain the bucket of oil, generally iron sheet or plastic material makes drum, steel drums all, metal bucket,
Plastic Drum, ton bucket, kilolitre bucket or other containers are likely to be damaged during long-term transport, use, cause to leak.
Need anti-bring disaster upon in possible trouble.The oil drum of these storage oil products, chemicals and hazardous chemical is placed on Sheng leakage pallet（Also it is anti-leak
Disk is let out in pallet, anti-overflow pallet, control, contains leakage clamp etc.）, contain leakage platform（Also anti-overflow platform, anti-leak platform are）, IBC contain leakage support
Disk（Also IBC anti-leak trays are）On.Contain leakage pallet, contain leakage platform, anti-leak platform have it is firm in structure, can be grasped with fork truck
The characteristics of making, be anti-skidding, being set with, when leaking, all leakage liquids will flow automatically along pallet or platform grid
In the Sheng drain region for entering pallet or platform, ground, corridor or passage will not be flowed to.Containing leakage pallet and containing leakage platform all has draining
Plug, when leaking to a constant volume, can empty the liquid of leakage.The liquid largely leaked can be with direct reuse.
Blowing is also referred to as hollow blow molding, a kind of plastic working method quickly grown.Blow molding process is in World War II
Period, start to be used to produce low density polyethylene (LDPE) bottle.The later stage fifties, with the birth and blow molding of high density polyethylene (HDPE)
The development of machine, blow molding technology are widely applied.The volume of hollow container has employed calculating up to thousands of liters, some production
Machine controls.There are polyethylene, polyvinyl chloride, polypropylene, polyester etc. suitable for the plastics of blowing, 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 more
Layer blowing and stretch-blow.Thermoplastic resin is extruded or is injection moulded obtained tubular plastic parison, while hot（Or it is heated to soft
Change state）, it is placed in split cavity, is passed through compressed air after mold closing in parison immediately, makes plastic parison inflation and be close to mould
Have on inwall, through cooling and demolding, that is, obtain various hollow products.The manufacturing process of inflation film is blown with hollow product in principle
Mould quite similar, but it is without using mould, and from the angle of plastic processing technology classification, the moulding process of inflation film is generally included in
In extrusion.Blow molding process during World War II, starts to be used to produce low density polyethylene (LDPE) bottle.The later stage fifties,
With the birth of high density polyethylene (HDPE) and the development of blow molding machine, blow molding technology is widely applied.The body of hollow container
Product has employed computer control up to thousands of liters, some production.There is polyethylene, polyvinyl chloride, poly- suitable for the plastics of blowing
Propylene, polyester etc., the hollow container of gained are widely used as industrial packaging container.
Extrusion-blown modling is a kind of method for manufacturing hollow thermoplastic's product.The blowing object being widely known by the people have bottle, bucket, tank,
Case and all packaged foods, beverage, cosmetics, the container of medicine and commodity.Big blow-molded container is generally used for chemical industry production
In the packaging of product, lubricant and bulk material.Other blow-molded articles also have ball, bellows and toy.For auto manufacturing,
Fuel tank, car damper, backrest, center rest and handrail and headrest coating are blowing.For machinery and
Furniture manufacturing industry, blow molding part have shell, door frame, frame processed, terrine or to the chamber for having an open surface.Polymer mixture is standby
It is defined as a kind of process for making polymer or polymeric system upgrade by melt mixed.Mixture process is from single additive
To be added to multiple additives processing, polymer alloy and the mixed training of reactivity, its scope very wide.It is estimated that the U.S. 1/3rd
Polymer production to pass through mixture.Mixed ingredients can be customized according to the performance requirement of final application.Compounded product has miscellaneous
Mixed performance, such as high glaze and excellent impact strength, or precision moding and good rigidity.
Closure pressing speed is slower in process for the current existing blow mold for oil drum, and stability is not high, causes
Processing efficiency is low, and product does not reach inadequate wall thickness.
