Abstract
The invention discloses a manufacturing process of an inflation-free ethylene vinyl acetate copolymer (EVA) football. The manufacturing process comprises the following steps that firstly a set of injection mold is prepared; a molding cavity for a hollow ball body and a ball surface cover is formed in the die; then composite materials are stored on an injection molding hopper of an injection molding machine and injected into the die through an injection lance; and finally, the injection molding ball body and the injection molding ball surface cover are placed into sizing grooves to be sized, cooled through cold water and bonded through glue. According to the manufacturing process, the football is made of EVA, the process is simple, manufacturing is easy, when a finished football product is used, the football has sufficient elasticity and is free of inflation, using is convenient, and the service life is long.
Description
[technical field]
The present invention relates to sports articles for use and manufacture field, be specifically related to a kind of manufacture craft of exempting to inflate EVA football.
[background technology]
Through the reform and opening-up of 30 years, the economic develop rapidly of China, broad masses of the people's living standard generally improved.More pay attention to take exercises, make great efforts improve fitness, object of promoting longevity.The international Olympic Games held in China for 2008, have also evoked the upsurge that the whole people join into sports, and the such as sport balls motion that joins into sports is a kind of effective method kept fit.
The football of present use generally adopts leather shoes or rubber to make, it is suitable for sports tournament, but because it is heavier, harder, be not suitable for teenager, beginner and person in middle and old age to use, and this ball is leather or the artificial material of making pre-sanction in the outside of bladders when manufacturing, because of a little complex process, manufacturing cost is high, all these defects can not meet each colony of nationwide fitness programs to the needs of football sense, in addition, usual football needs inflation, uses inconvenience, exempts from inflation EVA football because this creator a little invents one.
[summary of the invention]
In order to overcome above shortcomings part in prior art, the object of the present invention is to provide a kind of manufacture craft of exempting to inflate EVA football.
In order to reach above-mentioned object, the present invention adopts following concrete technical scheme: a kind of manufacture craft of exempting to inflate EVA football, comprises the steps:
(1) mould is prepared: prepare a set of injection mold and comprise upper die and lower die, be provided with the shaping mold cavity of hollow sphere and sphere lid in upper die and lower die, the temperature of upper die and lower die is 150-250 DEG C;
(2) injection moulding prepares: stored by composite in advance on the injection moulding hopper of injection machine, and injection machine has an injection gun barrel, can inject composite in injection mold;
(3) injection mo(u)lding: injection mold is placed on injection machine framed on, start injection machine, the injection gun barrel of composite is carried out injection moulding toward the upper die and lower die of injection mold, each section of temperature of injection gun barrel is 65-120 DEG C, injection temperature is 100-120 DEG C, injection time is 280-350 second, penetrate after gun barrel has been injected and automatically can move back seat, the composite melting of molten condition is from being attached in upper die and lower die die cavity, after 5-20 second, die sinking, takes out the injection moulding spheroid in injection mold and injection moulding sphere lid, stand-by;
(4) finished product sizing: the injection moulding spheroid in step (3) is put into fixed slot, then in injection moulding spheroid, fill cold water, cover injection moulding sphere lid, cool time is 60-180 second, finally the water of injection moulding spheroid is outwelled, injection moulding sphere lid and injection moulding spheroid are bonded by glue.
Further, composite described in the invention described above is made up of EVA, POE, stearic acid, zinc oxide, titanium platinum powder, look mother, blowing agent and bridging agent.
Further, EVA described in the invention described above adopts ethylene-vinyl acetate copolymer.
Further, POE described in the invention described above adopts polychloride vinyl.
The present invention's advantage is compared with prior art: it is simple that the present invention adopts EVA material to make football technique, is convenient to manufacture, self has enough elasticity when finished product uses, and non-inflatable, easy to use, long service life.
[accompanying drawing explanation]
Fig. 1 is exploded view of the present invention;
Below in conjunction with accompanying drawing, the present invention is described in further detail.
[detailed description of the invention]
In order to explain technical scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.
Refer to shown in Figure of description 1, the present invention is a kind of manufacture craft of exempting to inflate EVA football, comprises the steps:
(1) mould is prepared: prepare a set of injection mold and comprise upper die and lower die, be provided with the shaping mold cavity of hollow sphere and sphere lid in upper die and lower die, the temperature of upper die and lower die is 180 DEG C;
(2) injection moulding prepares: stored by composite in advance on the injection moulding hopper of injection machine, and injection machine has an injection gun barrel, can inject composite in injection mold;
(3) injection mo(u)lding: injection mold is placed on injection machine framed on, start injection machine, the injection gun barrel of composite is carried out injection moulding toward the upper die and lower die of injection mold, each section of temperature of injection gun barrel is 75 DEG C, 80 DEG C, 85 DEG C, 90 DEG C, injection temperature is 105 DEG C, injection time is 300 seconds, penetrate after gun barrel has been injected and automatically can move back seat, the composite melting of molten condition is from being attached in upper die and lower die die cavity, after 10 seconds, die sinking, takes out the injection moulding spheroid 1 in injection mold and injection moulding sphere lid 2, stand-by;
(4) finished product sizing: the injection moulding spheroid in step (3) is put into fixed slot, then in injection moulding spheroid 1, fill cold water, cover injection moulding sphere lid 2, cool time is 80 seconds, finally the water of injection moulding spheroid is outwelled, injection moulding sphere lid and injection moulding spheroid are bonded by glue.
