Abstract

The utility model relates to a mold molded through hot pressing processing to a chemical staple fiber. The utility model consist of an upper mold and a lower mold, the utility model is characterized in that a plurality of holes evenly arranged at intervals and used to let the high temperature air in are drilled on the mold plates of the upper mold and the lower mold. The chemical staple fiber mattress core produced by the mold, such as a pillow core, a mattress core, or a toy core which not only can be molded according to the shape of the mold, but also enables the mattress core after being molded to have a certain resilience ability from the surface to the inner core, and the design requirement to the product can be met through controlling the baking room temperature of molds, the blast intensity of the mold small hole and the time for hot pressing.

Description

A kind of mould that is used to make the staple fibre bedding core

Technical field

The utility model relates to a kind of mould of processing usefulness, relates in particular to a kind of mould to staple fibre hot pressing machine-shaping.

Background technology

Because a lot of staple fibres have advantages such as nonpoisonous and tasteless, as polypropylene fibre, terylene etc., it is more and more many to make the kind of commodity with them in the market.For example come filling pillow, back cushion and toy and so on article with them.But the shape of these article is finalized the design by other holding articles (as fabric, leather etc.) fully.As working as pillow with it, then made pillowcase earlier, then these short fibers are filled into.Pillow of making like this or back cushion, fluffy having a surplus, and pressure-bearing is too poor, also have some short fibers to analyse simultaneously unavoidably and expose the fabric outside, cause allergic or be inhaled into lung, unhealthful.So someone has developed a kind of mould, be about to short fiber and withhold in mould, die surface is heated, short fiber is finalized the design at a certain temperature.Though the pillow back cushion that processes has like this avoided short fiber from the separating out of fabric face, the surface of moulding is also more strong, and pillow back cushion in-core layer is still more fluffy, not withstand voltage.

Summary of the invention

The utility model is at the defective of the mould existence of above-mentioned processing staple fibre bedding core, structure to mould is reformed, concrete technical measures are as follows, this mould that is used to make the staple fibre bedding core is made up of upper die and lower die, it is characterized in that on the template of upper die and lower die, being drilled with many holes that are used to feed high temperature air, the aperture is φ 4mm to φ 10mm, and limit, the hole spacing in adjacent two holes is not less than 2mm; Its feature also is should be welded with the wallboard of certain altitude around counterdie.

The staple fibre bedding core of making according to certain technology in order to mold, as pillow, bedding core or toy core, can be according to the shape typing of mould, can make the bedding core after the typing from the surface to the inner core, all have certain anti-pressure ability again.And the anti-pressure ability of this bedding core or title bounce-back ability, can reach the designing requirement of product by control mould drying room temperature with to mould aperture blast intensity and duration thereof.The size in hole should be looked product thickness and the designing requirement of product is selected according to practical experience.

The specific embodiment

Below in conjunction with Fig. 1, Fig. 2, Fig. 3 embodiment is done a detailed description, this mould is used for making pillow, it is made up of patrix 3 and counterdie 4, patrix 3 and counterdie 4 are made the pillow shape respectively half, patrix 3 each side has a handle 1, be welded with wallboard 5 around the counterdie 4, the height of wallboard should be according to depositing how much determining of short fiber material.Be drilled with many evenly spaced apertures 2 on the template of patrix 3 and counterdie 4 respectively, the aperture is 6mm, and the spacing at center, hole is not less than 8mm.Technology with this Mold Making pillow is as follows, on counterdie 4, pile up the staple fibre of a certain amount of (through what calculate), mould is sent into drying room, adjust and control well the temperature of drying room, continue for some time, patrix 3 is withheld on counterdie 4, be aligned in following aperture 2 air blast on template of the top and counterdie 4 of patrix 3 simultaneously respectively with air blast, hot blast directly can be blown to inner core, withheld the short fiber in mould, under the specific temperature of rule, make short fiber produce little adhesion state to each other, make whole pillow be similar to a honeycomb network structure, after continuing for some time, can turn off the blast and reduce the drying room temperature, open patrix 3, can take out pillow.

For the making of other bedding cores, comprise back cushion, sofa cushion, sofa handrail core and need make the cloth art furnishings and the cloth art toy of liner with inner core, all can make according to the preparation method of above-mentioned pillow.The mould of shape whatsoever, its key is must bore to open many thickly dotted apertures on the template of upper and lower mould, so that hot blast is blown into the inner core depths, all short fibers can both be sticked to each other, and forms uniform honeycomb network structure.Need to prove that the temperature that will control in the above-mentioned technology, lasting time, the intensity of air blast and the size of small aperture select, all should and grope to determine with practice as calculated according to the characteristic of different staple fibres to the designing requirement of product.And the design of the density in hole should take into account mould strength and rigidity.

Claims

1, a kind of mould that is used to make the staple fibre bedding core, form by patrix (3) and counterdie (4), it is characterized in that on the template of patrix (3) and counterdie (4), being drilled with many holes (2) that are used to feed high temperature air, the aperture is φ 4mm to φ 10mm, and limit, the hole spacing in adjacent two holes is not less than 2mm;

2, a kind of mould that is used to make the staple fibre bedding core according to claim 1 is characterized in that should being welded with wallboard (5) around counterdie (4).
