Description
Technical field
The present invention relates to middle technical field of polymer materials, especially a kind of wiper soft-hard coextrusion flow-disturbing wing calibrator.
Background technology
The flow-disturbing wing is one of core component of automobile Novel windscreen wiper, and its structure is that soft hard two kinds of different materials extrude realization by co-extruding mould.Be mainly the circular arc wind surface according to aerodynamic principle design and supporting surface composition, utilize windage during motor racing, for automobile windshield wiper blade provides uniform thrust, make scraping blade can not be made to scrape outlet capacity by air-flow lifting and decline.
Flow-disturbing wing structure comprises assembling skeleton and flow-disturbing wing main body, as accompanying drawing 1, assembling skeleton 1 is the thermoplastic that hardness is higher, and its effect is to provide reliable enclasping force and stable equipment size, and the rubber flow-disturbing wing main body of upper end is played to the effect supporting and draw; Flow-disturbing wing main body 2 is softer thermoplastic elastic material, is mainly the circular arc wind surface according to aerodynamic principle design and supporting surface composition, utilizes windage during motor racing, for automobile windshield wiper blade provides uniform thrust.
The sizing of soft-hard coextrusion profile shapes, different according to its raw material, surface requirements or shape, there is multiple sizing mode, as shaped in airtight vacuum sizing, pressurization sizing, open slip sizing and hollow, its shaping equipment also differs widely simultaneously, and various different mode has its advantage, how to optimize the structure of stock mould, can play better effect, be then the current problem needing research.
Summary of the invention
The object of the invention is: a kind of wiper soft-hard coextrusion flow-disturbing wing calibrator, it is applicable to the production of the flow-disturbing wing that soft-hard coextrusion goes out, and can improve the surface quality of product, and ensures the stability of type-approval process, to overcome the deficiencies in the prior art.
The present invention is achieved in that wiper soft-hard coextrusion flow-disturbing wing calibrator, comprise mounting base, it is bulge-structure in the middle part of the end face of mounting base, clamping plate is respectively equipped with in mounting base bulge-structure both sides, be provided with two pieces of pressure strips at the top of clamping plate, between mounting base, clamping plate and pressure strip, form mold cavity; Pressure strip is provided with lubrication cascade, and lubrication cascade is communicated with mold cavity, and mounting base, clamping plate and pressure strip are provided with cooling water channel.
The width L of lubrication cascade is 0.1-0.2mm.
Described cooling water channel, be specially and be provided with cooling water channel S5 on mounting base, be respectively equipped with cooling water channel S1 and cooling water channel S2 at clamping plate, the pressure strip of sizing supporting surface is provided with two cooling water channel S3, cooling water channel S4 on the pressure strip of sizing wind surface.
Cooling water channel S1 is equal with the cross-sectional area of cooling water channel S2, total cross-sectional area of cooling water channel S3 is equal with the cross-sectional area of cooling water channel S4, and total cross-sectional area of cooling water channel S1, cooling water channel S2 and cooling water channel S5 is equal with total cross-sectional area of cooling water channel S3 and cooling water channel S4.
Mounting base provides base position for whole shaping equipment, simultaneously by the cooling water channel S5 of medium design, and can the bottom size of the cooling and shaping flow-disturbing wing.
Clamping plate is divided into two pieces, left and right, by coordinating with the position of base plate, the sizing space that formation and flow-disturbing wing hard skeleton adapt, is mainly used in the sizing of flow-disturbing wing rigid plastic armature, simultaneously by cooling water channel S1 and S2 of medium design, for being flow-disturbing wing hard skeleton cooling and shaping.
The forming surface of pressure strip has the construction profile with flow-disturbing wing main body same shape, but size slightly strengthens, its effect is mainly for the plastics that flow-disturbing wing main body is softer provide support and guide effect, simultaneously by cooling water channel S3 and S4 of medium design, softer flow-disturbing wing main body stock is tentatively cooled, makes it by not bending during stock mould or being out of shape.
The purpose of design of cooling water channel meets the requirements to obtain shape, dimensionally stable is reliable, the flow-disturbing wing that flexural deformation is less, according to the special construction of windscreen wiper with the flow-disturbing wing, material composition and instructions for use, bend for preventing extruded product, cooling die cross section and whole length direction homogeneous temperature need be ensured, thus guarantee the cooling of the flow-disturbing wing evenly, guarantee product is straight, just must ensure to extrude stock being cooled uniformly by each face during cooling and shaping device, therefore, each position coolant flow channel cross section must be as far as possible equal, i.e. S1=S2, S3=S4, S3+S4=S1+S2+S5.
For guaranteeing that stock that flow-disturbing wing co-extruding mould extrudes is obtaining sufficient lubrication by during shaping equipment, that avoids causing because frictional resistance is excessive is bonding, distortion, the phenomenons such as snap gauge, the present invention is devising lubrication cascade structure, as shown in Figure 3, lubrication cascade width L determines the size of lubrication water, L can not be excessive or too small, time excessive, easily cause product Local cooling violent and be out of shape snap gauge, also easily water ripples are formed at product surface, affect product quality, when L is too small, because lubrication is not enough, also the adhesive mould easily caused and snap gauge occurs, the present invention determines that L is proper between 0.1-0.2mm.
For guaranteeing that stock that flow-disturbing wing co-extruding mould extrudes is obtaining sufficient lubrication by during shaping equipment, avoid due to the excessive distortion caused of the lubrication water yield, snap gauge, surface water waviness phenomena, or the less generation mold sticking of the lubrication water yield, in mold lubrication cascade width L and the timing of lubrication hydraulic pressure one, certain proportionate relationship is there is between production hauling speed U and lubrication cascade separation L1, if this extruded material needs larger speed of production, then in order to keep certain lubricating irrigation flow amount, lubrication cascade spacing L1 needs to get the small value, otherwise, then need when Design of Dies to increase L1, the proportionate relationship that flow-disturbing wing extruded velocity U of the present invention and shaping equipment lubricate cascade separation L1 is L1:U=1:1500,
Owing to have employed technique scheme, compared with prior art, the present invention is according to the special construction of windscreen wiper with the flow-disturbing wing, material composition and instructions for use, devise a set of special open slideway shaping equipment, for realizing the extrusioning shaping of product, it adopts the stock mould of fabricated structure, and corresponding cooling water channel is provided with on each building block, each building block structure of stock mould is simple, easy production, the distributed architecture of cooling water channel can ensure that the cooling effect in stock mould is even, the present invention is also provided with lubri-cating-water groove on stock mould, it can be in process of production, the mold cavity surface of stock mould is made to produce water membrane, make stock obtaining sufficient lubrication by during shaping equipment, while progressively production technology being adjusted to and meeting product size, that avoids causing because frictional resistance is excessive is bonding, distortion, the phenomenons such as snap gauge.Structure of the present invention is simple, and easily produce, with low cost, result of use is good.
