Description
Technical field
The present invention relates to a kind of foaming mould, especially automotive seat soft seal foaming mould.
Background technology
The inside of automotive seat is mainly still supported using sponge main body, spacing while playing a supporting role
Seat comfort degree, the sponge main body in automotive seat needs to use foaming processing technology in process, and this is accomplished by making
Foaming mould is used, but the die joint of existing automotive seat mould is inclined-plane, poor sealing, so as to cause sponge upper and lower mould
The sign an undertaking position of conjunction produces hard-edge, flash, influences the precision and outward appearance of sponge so as to influence the quality and comfort level of seat.
Traditional foaming mould heating uses hot water heating, i.e., the mode of stainless steel waterpipe, its cloth are connected in die surface
There is limitation in pipe, because it is difficult to bend and volume is big, it is impossible to be uniformly distributed in die surface, heat uneven, there is temperature
Difference, causes foaming product surface not bright and clean, and influence product is attractive in appearance.And the heat time is more long, low production efficiency, die cost are high.
At present, the American-European or Japanese sponge foaming die of either domestic or import, material is 103 or 104
Cast aluminium, its processing method is roughly the same, that is, digital control processing after casting, therefore current foaming mould has problems with：By
It is cast aluminium in the material of mould, mold cavity surface hardness is low, does not note somewhat when inserts or cleaning mould is placed, worksheet
Face will be scratched, so as to have impact on mold use life-span and product quality；Because mould is sand casting, so mould
Working surface density is relatively low, and surface roughness can only achieve Ra1.6, in order to be convenient in demoulding during work, the factory of automotive seat
Family has to use substantial amounts of releasing agent, so as to improve production cost.
Releasing agent is a kind of functional material, and it is sprayed at into die surface can prevent polyurethane foam and die surface
Bonding.Because the isocyanates composition in polyurethane foam raw material has caking property, isocyanic acid ester bond therein can be produced with metal
The stronger bonding action of life, so needing to use suitable releasing agent to prevent the bonding of polyurethane foam product and mould, takes off
Also known as mould release, it is to separate product with die surface for mould agent, plays a part of a physical separation, so as to be conducive to product
Point mould, but releasing agent in spraying process because liquid is atomized by spray gun, so be easy to be dispersed into air,
Air is polluted, harm people's is healthy.
The content of the invention
To solve the above problems, the present invention provides that a kind of mold cavity surface is hard, be difficult to scratch, heat with quickly, from the demoulding
Automotive seat soft seal foaming mould, concrete technical scheme is：
Automotive seat soft seal foaming mould, is made up of punch-pin and cavity plate, and the mold cavity surface of the punch-pin and cavity plate is from inside to outside
It is sequentially provided with hardening coat and release coating, seal groove is respectively equipped with the matched moulds of the punch-pin and cavity plate, on the seal groove
Equipped with sealing strip；Heater strip and temperature sensor are respectively equipped with inside the punch-pin and cavity plate.
The hardening coat is tungsten carbide coating, and the thickness of hardening coat is 0.1 ~ 0.3mm.
The release coating is PTFE base anti-stick coating, and release coating thickness is 0.1 ~ 0.3mm.
The sealing strip is silica gel sealing bar.
The heater strip is silica gel heating line, and heater strip is distributed in punch-pin and cavity plate, and above die cavity.
Tungsten carbide hardness is very high, and easy to process using spraying method, hardness is high, reaches HRC50 ~ 60.Greatly improve mould
Have the hardness of die cavity working surface, extend repair a die time and the service life of mould, common metalwork is not easy to scratch again
The working surface of mould, makes to regrind in forming process and damages the working surface of mould, greatly improves the mold use longevity
Life, service life can reach more than 5 times of present mould；The roughness of mold working surface is improve, by original Ra1.6
More than Ra0.8 is brought up to, due to die cavity smoother, the demoulding is also relatively easy.
PTFE base anti-stick coating has superpower releasing performance, and hydrophobic performance and oleophobic performance are splendid, and foam poly- ammonia
Ester completely will not adhesion.Wear-resistant scratch resistant filler is increased, coating has hardness and toughness higher, and coefficient of friction is low, anti-friction
Wipe.Release coating has the corrosion of all kinds of organic compounds of resistance, and coating compactness is good, and anti-corrosion chemical resistance is excellent.Apply
Tunic is thick most thick up to 0.3mm, and using can be continuing with after being polished with abrasive paper for metallograph after a period of time, greatly promoting mould makes
With the time, cost is reduced.
Heater strip is silica gel heating line, and heater strip is distributed in punch-pin and cavity plate, and above die cavity, while being equipped with temperature
Probe, is heated using crawl, and temperature control is accurate, and temperature is uniform, and heating is fast.Silica gel heating line is soft, has stronger in wiring
Plasticity, be adapted to irregular wiring, can arbitrarily bend, thus wiring when can each corner of uniform fold.
Silica gel sealing bar high temperature resistant, corrosion-resistant, good airproof performance, are prevented effectively from the situation that gas leakage causes overlap and hard-edge, carry
The qualification rate of product high.
Compared with prior art the invention has the advantages that：
The automotive seat soft seal foaming mould structure reliability of present invention offer, mold cavity surface hardness are high, the demoulding is easy, heating
Hurry up, homogeneous heating, die life is long, use cost is low, the bright and clean attractive in appearance, qualification rate of foaming product surface is high.
Specific embodiment
In conjunction with embodiment, the invention will be further described.
