Abstract
The invention discloses a manufacturing process of intra-mold molding supplies. The manufacturing process comprises the following steps that 1, matching is carried out on raw material particles and foaming glue, and sufficient stirring is conducted, so that the outer surface of each raw material particle is covered with a glue layer; 2, the raw material particles with the outer surfaces provided with the glue layers are put in a cavity of a molding mold; and 3, heating and pressing are conducted, the foaming glue is made to generate foaming bonding, and the adjacent plastic particles are firmly bonded together through the glue layers. Compared with the prior art, material selection is quite rich, and the manufacturing process has the characteristics that the cost is low, products are varied, and the appearance effect is good.
Description
Technical field
The present invention relates to sports goods or commodity machine-shaping field, what be specifically related to is a kind of production technology of in-molded articles for use, and these in-molded articles for use can be protector, ground cushion, cushion, shoe-pad, sole and vamp.
Background technology
In-molded articles for use are generally the technique adopting such as injection moulding or foamable, go out at in-mold molding the product that profile and die cavity match.Shooting Technique is the method for traditional a kind of industrial products production moulding, is generally divided into again rubber injection mold and plastics injection moulding, and wherein plastics injection moulding is utilized by the plastics of melting pressure to note in plastic product mold, can obtain wanting various working of plastics after cooling forming.
Foamable technique refers to such as with raw material such as plastics, the auxiliary material such as catalyst, foam stabiliser, blowing agent in addition, by physical blowing or crosslinked foaming, make in plastics, to occur a large amount of trickle foam, volume increases, and density reduces, and flexible foamed quality of materials is light, pliability good, possess the functions such as buffering, sound-absorbing, shock-absorbing, insulation, filtration, be widely used in the industries such as electronics, household electrical appliances, automobile, Leisure Sport.
Two kinds of production and processing modes of above-mentioned in-molded articles for use, bring a lot of comfortablenesses really to the life of people.But, the foamable technique that prior art adopts, at least there is following defect in it:
One, it is rather strict to the selection of expanded particle, according to current Normal practice, general EVA expanded particle or the TPU expanded particle all outwards need being bought high-quality by factory, so can utilize the characteristic of expanded particle itself, realize adjacent expanded particle and produce foaming fusion each other, strict so based on selection, production cost is all higher, and be difficult to has further breakthrough on cost.
Two, be all the characteristic utilizing particle itself based on existing foamable technique, namely before foaming after, originally larger change can be there is in physical characteristic in particle, could realize merging, the external aesthetic feeling of particle like this itself can change, cannot restore original that third dimension, reduce external aesthetic effect; Moreover based on external that relief disappearance, make, when products such as shaping such as shoe-pads, to lose certain massage effect.
Three, be all the characteristic utilizing particle itself based on existing foamable technique, in order to realize fully merging each other, very exquisite when selection particle, so cannot select arbitrarily the particle of difformity and different colours to process, namely often one deck is constant in appearance for product that prior art forms out, the satiety of various shape of particle filling and colourful outward appearance cannot be had, and then allow product have more the market competitiveness.
For the problems referred to above, the applicant, for above-mentioned defect further investigation of the prior art, has this case to produce then.
Summary of the invention
Main purpose of the present invention is the production technology providing a kind of in-molded articles for use, to solve when adopting foaming forming technique to make in-molded articles for use, has the problem that production cost changeability that the is high and product that forms out is weak, aesthetic appearance is poor.
In order to reach above-mentioned purpose, solution of the present invention is:
A production technology for in-molded articles for use, wherein, comprises the steps:
1. raw particles is good with foaming glue proportioning, stir, allow each raw particles all be coated with one deck glue layer in appearance;
2. appearance is put into the die cavity of mould with the raw particles of one deck glue layer;
3. heating is exerted pressure, and allows foamed glue aquatic products germ-vesicle bond, adjacent plastic particles is bonded together by glue layer is secured to one another.
Further, step 1. in, the minimum requirements of described glue layer is: raw particles surface all needs to be coated with foaming glue.
Further, step 1. in, this raw particles with foaming glue be 60%:40% according to the proportioning of percentage by weight.
Further, step 3. in adopt flat late heat transfer die casting machine to realize heating to exert pressure.
Further, step 3. in heating temperature be 50-70 DEG C.
Further, this raw particles selects TPU particle, EVA particle, tealeaves, bagasse, one of rubber particles or sponge particle or two or more combination.
Further, this raw particles selects cylindrical, strip, one of rugby shape or spheroidal particle or two or more combination.
Further, these in-molded articles for use are protector, ground cushion, cushion, shoe-pad, sole or vamp.
Further, this foaming glue is made up of following component:
Combined polyether: 15-20wt%;
Combination PTMG: 35-45wt%;
Methylene two vulcabond: 35-45wt%;
Organosilicon foam stabilizer: 0-1wt%;
Ultra-violet absorber: 0-1wt%;
Glycols chain extender: 0-3wt%;
Organic bismuth catalyst: 0-0.5wt%.
After adopting said structure, the production technology of a kind of in-molded articles for use that the present invention relates to, it is good with foaming glue proportioning by raw particles, inserts in mould after stirring, being exerted pressure by heating makes foamed glue aquatic products germ-vesicle bond again, and realizes the processing and forming of a complete product; Compared with prior art, at least there is following beneficial effect in the present invention:
One, the present invention utilizes the foaming of foaming glue to realize raw particles connection each other, raw particles itself is not then changed to the characteristic of himself, so very flexible for the selection of raw particles, such as it can directly select some dead meals to carry out production and processing, thus solves and to there is the high problem of expense based on Material selec-tion.
Two, the present invention can adopt the combination of TPU particle and glue to carry out the product of the softnesses such as molded shoe pad, and realize dual softness after utilizing the softness of TPU particle self cooperation glue, effect is very good; And based on the difference of forming principle, namely can not change to raw particles itself, to the requirement of raw particles be only requirement its with foaming glue can fully bond, to the non-constant width of the range of choice of raw particles, and even substantially to shape and color not restriction and the requirement to some extent of raw particles, and then the characteristic of some raw particles in shape and color can be kept on molded product, thus bring satiety and colourful outward appearance to whole in-molded articles for use, substantially increase the competitiveness of product in market.
