Description
Technical field
The utility model relates to a kind of technical field of mold, particularly relates to a kind of oil can 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.
The blowing of hollow product comprises three main method: extrusion-blown modling: be mainly used in not processed by the parison supported; Injection-blow molding: be mainly used in the parison processing supported by metallic core; Stretch-blow: comprise and extrude stretching one blowing, injection one stretching one blowing two kinds of methods, the goods of biaxial orientation can be processed, greatly reduce production cost and improve product properties.In addition, multilayer blow moulding, compacting blowing, dipping blowing, foaming blowing, tri-dimensional blow moulding etc. is also had.But 75% of blow-molded article uses extrusion and blow molding, 24% is shaping with injection-blow molding, and 1% uses other blow molding; In all blow molded products, 75% belongs to biaxial tension product.The advantage of extrusion-blown modling is that production efficiency is high, and equipment cost is low, and the range of choice of mould and machinery is wide, and shortcoming is that percent defective is higher, and recovery, the utilization of waste material are poor, and the THICKNESS CONTROL of goods, the dispersiveness of raw material are restricted, must carry out deburring operation after shaping.The advantage of injection-blow molding does not have waste material to produce in process, can control the wall thickness of goods and the dispersion of material well, and thin neck formed product precision is high, and product surface is bright and clean, can carry out small lot batch manufacture economically.Shortcoming is that former cost is high, and is only suitable for little blow-molded article to a certain extent.
Hollow blow molding is divided into again injection-blow molding, extrusion-blown modling and stretch-blow, and injection-blow molding first plastics has been made die bed base with injection molding method, then carries out blow molding in parison immigration blow molding die.Extrusion-blown modling forming process, pipe is directly extruded by extruder, and hangs from above and be installed in the die cavity separated in advance immediately below head; Matched moulds immediately after sagging parison reaches the length of regulation, and pipe cuts off by the otch of pattern tool; Pass into compressed air from the aperture of mold parting surface, make preform blowup be close to die wall and shaping; Pressurize, until goods in die cavity after cooling and shaping die sinking take out goods.
The thermoplastic kind be shaped for hollow blow molding is a lot, and the most frequently used raw material is polyethylene, polypropylene, polyvinyl chloride and thermoplastic polyester etc., and the packing container of the various liquid that is commonly used to be shaped, as various bottle, bucket, tank etc.The method distinguishing extrusion-blown modling and injection moulding blowing (comprising note stretch blow) is observed bottom goods, and what the injection point of a navel sample was arranged at bottom is injection moulding blowing or note stretch blow goods, and what a spue line was arranged at bottom is extrusion-blow molding product.
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.Industrial part two class.Wherein container comprises: packing container, large volume storage tank, and collapsible container.But along with the maturation of blow molding process, the blow-molded article of industrial part gets more and more, and range of application is also increasingly extensive.At present, container accounts for the market share of 80%, annual growth about 4%; And industry and structure goods account for 20% of total amount, every annual growth rate is 12%.The growth of container consumption is the range of application of turn-knob plastic containers constantly to expand, and the consumption of industrial goods increases mainly caused by the improvement of New Processing, as multilayer parison extrude, twin shaft is extruded, non-axis symmetry blowing etc.
The existing blow mold complex structure for oil can processing at present, processing cost is higher, is inconvenient to operate.
