Description
Technical field
The present invention relates to a kind of production method of sound insulating pad, more particularly, to a kind of system of filled formed sound insulation pad for automobile
Make method.
Background technology
At this stage, to reach the requirement of comfort, all of part step in the sound insulating pad of floor in the passenger compartment of automobile industry
It is essentially identical to step on the soft or hard degree of area requirement.Part is compressing using the thick material of individual layer at this at present；When part shape
During shape big rise and fall, using such a molding mode, shape can not completely in place, and since material is thick, the part after shaping is ironed
Place it is partially hard, and thick place is then partially soft, and the soft or hard degree for being unable to reach all positions is identical.
Chinese invention patent ZL201010237114.X discloses a kind of production method of filled formed sound insulation pad for automobile,
This method is filled fibrous material according to the thickness situation at each position using fill system using air-flow mixing filling molding mode
Into mesh mould, then compression molding, last Water Cutting punching rim charge obtain product.Compared with prior art, which utilizes spy
Different charging port, ensures to be attained by identical density in the place of became uneven, i.e. isodensity not uniform thickness, so as to reach soft everywhere
The hard identical mesh of degree, and good forming effect, in addition can also save material, and thin place need not with thick place in die cavity
Identical material is squeezed into, due to directly squeezing into mould, leftover pieces are reduced.But there are following defect for the invention：Production efficiency
It is extremely low, about 1/5 minutes, and if locally thering is density to increase, can not there is the adjusting of very big density.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of isodensity not uniform thickness,
The production method of the filled formed sound insulation pad for automobile of good forming effect.
The purpose of the present invention can be achieved through the following technical solutions：A kind of making of filled formed sound insulation pad for automobile
Method, it is characterised in that this method is using air-flow mixing filling molding mode, the thickness feelings using fill system according to each position
Fibrous material is filled into filling molding mesh mould by condition, and diverse location thickness is made not by filling molding mesh mold shape
With fiber cake, compression molding in shaping mesh mould is put into after reheating, is produced finally by die cutting die punching rim charge
Product.
The method specifically includes following steps：
(1) cloth is bloomed, fused fiber and sponge particles are by weight (50~62): (35~45): (3~5) input
Air-flow mixing is carried out in opener, uniformly mixed raw material are sent into the storage hair case after shaking storehouse；
(2) filling molding mesh mould is closed；
(3) raw material are uniformly taped against on conveyer belt using shaking storehouse, raw material is blown into filling by spreading yarn fan
It is molded in mesh mould；After filling finishes, filling molding mesh mould automatically opens up, and obtains fiber cake；
(4) as conveyer belt, the fiber cake by obtained by is sent in heated oven, and a secondary baking oven mesh mould is arranged at heated oven top
Tool；By baking oven mesh mold clamping anchoring fiber cake, hot air shaping is opened, it is 180~250 DEG C to control heating-up temperature,
Heat 25~45sec, it is to be heated in place after, baking oven mesh mould open, fiber cake heating finish；
(5) the fiber cake after heating is conveyed by conveyer belt and tiled into shaping mesh mould, closed moulding mesh
Mould, with cold air cooling and shaping, cooling time is 25~45sec, obtains molding component；
(6) molding component is placed on die cutting die, molding punching rim charge, that is, obtain sound insulating pad product.
The filling molding mesh mould is located above conveyer belt, its side is equipped with feed inlet, and opposite side is equipped with discharging
Mouthful, it is equipped with the boss to match with sound insulation mat thickness to be formed at the top of die cavity, and die cavity top material is mesh plate, on mesh plate
Portion connects aspiration channel by seal closure.
The bottom cover of the seal closure is on filling molding mesh mould, and on the die cavity top of filling molding mesh mould
Partition plate is equipped with above portion's mesh plate, is offered on the partition plate and air outlet, the air outlet is equipped with stock cap, the air outlet
Positioned at one end of the discharge port close to filling molding mesh mould.
The paving yarn fan is arranged on the feeding side of filling molding mesh mould, and the air port alignment of paving yarn fan is filled into
The feed inlet of type mesh mould.
The material that the cloth is bloomed is：CO+PET+PAN；It is clothing factory's leftover bits and pieces shredding into fiber.
The material of the fused fiber is：PET staple fibers；During production, adhesive effect is played.
The material of the sponge particles is：PUR；The particle that automotive seat producer PU seat material are split into.
The loading of fiber cake is 6000~8000g/m in the filling molding mesh mould2。
Although Chinese invention patent ZL201010237114.X also discloses that a kind of sound insulation for making isodensity not uniform thickness
Pad, but production efficiency is extremely low, about 1/5 minutes, and if locally thering is density to increase, can not there is very big density
Adjust, and present invention employs flow line production mode, production efficiency height, 1/minute, and can locally increase close as requested
Degree has been met the requirements.
Compared with prior art, the present invention has the following advantages：
(1) special fill system is utilized, ensures to be attained by identical density, i.e. isodensity in the place of became uneven not
Uniform thickness, so that with reaching the mesh that soft or hard degree is identical everywhere, and good forming effect；
(2) material is saved, reaches identical effect, thin place need not squeeze into identical weight with thick place in die cavity
Material.
(3) production efficiency is high, about 1/minute.
