Description
Technical field
The present invention relates to the manufacturing process of a kind of glue spraying, a kind of manufacture method pressing from both sides flip-flop, belong to glue spraying system
Make technique applied technical field.
Background technology
Folder flip-flop represents fashion, free, active and happy, and therefore it is dragged by youthful favorite, existing folder toe
The manufacture method of footwear has two kinds, and one is boring method, and another kind is pressure sintering.
And both approaches exists a lot of weak point, the shoe sole print of both approaches is all formed when high temperature foams,
Its technological process is: the first step, and foam stricture of vagina processed, is placed in foaming machine by the mould being carved with corresponding decorative pattern, and expanded material is placed in mould
In tool, after having foamed, being fabricated to the big plate with decorative pattern, there is a lot of weak point in this flow process: 1), due to expand with heat and contract with cold
Effect, decorative pattern--the decorative pattern being particularly at big plate four limit can deform；2), in foaming process, material is spread to surrounding by centre,
Material skewness, big plate density is inconsistent；3), the finest flower can only be made by the coarse decorative pattern of comparison
Stricture of vagina, easily occurs that material is bonded on mould, it is impossible to the problem of the demoulding smoothly；Second step, blanking, after big plate cools down at normal temperatures,
With clicker press machine and stamping knife, big plate is cut into sole.The defect of this flow process is: less than rejected in advance big edges of boards corner material, is easily formed secondary
Product and waste product.
And the method for boring method is to use electric drill, remove material on recess and through hole relevant position, form recess and through hole,
The defect of this flow process is: because eliminating recess material, and shoestring is easily extruded from through hole, causes shoestring to disengage from sole.
And the method for pressure sintering is to act on the sole of recess and through hole relevant position with the hot-die after heating, heating
Sintering makes foam compresses, forms recess and through hole.The defect of this flow process is: during hot pressed sintering, and material occurs chemistry
Reaction, produces the toxic and harmfuls such as carbon monoxide, therefore, proposes a kind of manufacture method pressing from both sides flip-flop for the problems referred to above.
Summary of the invention
The purpose of the present invention is that provides a kind of manufacture method pressing from both sides flip-flop to solve the problems referred to above.
The present invention is achieved through the following technical solutions above-mentioned purpose, a kind of manufacture method pressing from both sides flip-flop, its manufacturer
Method specifically comprises the following steps that
Step A, foaming, be placed in die for shoe-sole in foaming machine, and expanded material is placed in mould, forms the big plate of bright finish；
Step B, sanction plate, after the big plate after step A being foamed cools down at normal temperatures, be cut into sheet；
Step C, sheet post bake, the sheet after step B is cut out plate carries out foamable in being placed in cold press；
Step D, sizing of colding pressing, be fixed on cold stamping die on cold press, by the sheet after step C post bake
It is placed in cold stamping die, carries out the sizing of colding pressing of a period of time, form shoe sole print and recess and through hole；
Step E, stamping-out, the pressing plate after step D is colded pressing, utilize punch press and stamping knife to carry out stamping-out；
Step F, making shoestring；
Step G, wear shoes band, the shoestring made in step F passes recess and the sole of through hole, the footwear that step D is made
The ball handle of band is held into the recess of shoe sole bottom.
Preferably, the sheet size in step B is adjusted according to cold stamping die size.
Preferably, step C heats detailed process as follows:
Sheet after step B is cut out plate is placed in cold press, and board temperature more than 130-150 degree, heat time heating time is
The 250-300 second.
Preferably, step D time of colding pressing is 3-5 minute according to thickness
Preferably, step D cold press pressure is 50-80 ton according to thickness.
Preferably, this kind of manufacture method is raw-material for ethene-vinyl acetate polymer or polyethylene one of which
Processing.
The invention has the beneficial effects as follows: after the big plate after present invention foaming cools down at normal temperatures, be cut into sheet, sheet size
Can be adjusted according to cold stamping die size, rejected in advance big edges of boards corner material, in order to avoid substandard products and waste product occurs in subsequent operation, carry
High finished product rate；Sheet post bake foams, and by second time of foaming, makes material distribution more uniform, and material density is more unified, more
It is easy to the sizing of colding pressing of material；Cold stamping die is fixed on cold press, sheet is placed in cold stamping die, carry out one section
The sizing of colding pressing of time, forms shoe sole print and recess and through hole；For sole other parts, extruded by cold stamping die
The decorative pattern of rear formation and recess and through hole position elasticity reduce, and eliminate the effect expanded with heat and contract with cold, and shoe sole print does not haves change
Shape；The problem not havinging " sticking to mould ", can make decorative pattern more closely；There is not chemical reaction, will not produce poisonous
Harmful gas；Recess and through hole non-deformability are higher, and shoestring is less susceptible to disengage with sole；The thickness of sole can be accurately controlled
Degree, hardness；Material distribution more uniform, it is to avoid occur sole warp deformation problem；To the pressing plate after colding pressing, utilize punch press and
Stamping knife carries out stamping-out, the rejected in advance leftover pieces of big plate, is difficult to substandard products and waste product occur, improves yield rate.
