Abstract
The invention discloses a manufacturing process of double-color double-density soles. The manufacturing process is characterized by comprising the following steps of: fixing an upper die and a lower die of a die in holes of a platform of an injection molding machine in a separated manner; respectively adding two EVA (ethylene-vinyl acetate copolymer) foaming raw materials with different colors and different rigidities into different material barrels, and controlling a temperature within a range of 55-60 DEG C simultaneously, so as to prevent the foaming raw materials from being foamed again; starting molding operation when the temperature is judged to be moderate on the basis that the materials are not foamed; respectively injecting the two EVA foaming raw materials with different colors and different rigidities into upper and low die holes, and adhering an upper template and a lower template after taking off a partition board; squeezing downward and finally molding; opening the upper die and the lower die of the die, and popping a finished product out of the die holes; and placing the taken-off finished product into a shaper for shaping. The entire process is realized through one-off injection through the EVA injection molding machine simultaneously, so that the production efficiency can be improved, and the production cost is further reduced.
Description
Technical field
The present invention relates to a kind of shoe-making process, refer in particular to a kind of manufacture craft of two-color dual-density sole.
Background technology
For improving the value of sport footwear product, general all sole can the making is shaped to form double-colored or the polychrome multi-density in the market, its main manufacturing process has two kinds of methods, its method one is to dig in advance notch at side edge of sole shoe or bottom surface, be provided with footwear limit fork or footwear bag sheet corresponding to the notch place, density and the color of this footwear limit fork or footwear bag sheet are different from sole, form through the bonding combination process.But such product exists topmost shortcoming to be owing to adopting different expanded materials bonding in making with using, when being subject to sunlight, temperature etc. and constantly affecting, adhesive glue will produce qualitative change, cause shoes fragile, simultaneously also improved production cost, increased artificial, glue raw material, machinery equipment and made workload.Its method two is that the EVA expanded beads of getting two or more different colours, different densities injects the different injection devices coarse-blank that foams, and then places in the die cavity of secondary frothing forming mould, and typing forms through the certain hour heating and cooling.It is oversize that this preparation method exists process time, increase artificial, the cost of raw material, and production efficiency neither be very desirable.
Summary of the invention
The present invention is directed to the disappearance of prior art existence, its main purpose provides a kind of manufacture craft of two-color dual-density sole, and it is simple that it has technique, and production efficiency is higher, can an ejection formation.
For achieving the above object, the present invention adopts following technical scheme: a kind of manufacture craft of two-color dual-density sole is characterized in that: this technique comprises the steps:
(1) the mould upper and lower mould separately is fixed in the ejection formation board hole;
(2) EVA of two kinds of different colours and different hardness foaming raw material are separately added in the different charging baskets, need control simultaneously temperature at (55-60) ℃, again foam with the raw material that prevent from foaming, when the material explanation temperature that do not foam is moderate, at this moment can enter forming operation;
(3) in the die cavity about the simultaneously injection of the EVA of above-mentioned two kinds of different colours and different hardness foaming raw material difference, and be placed with dividing plate between two moulds up and down, this dividing plate is to play the support patrix to press down and prevent the bi-material colour contamination, and two templates are together bonding up and down after taking away dividing plate; The material sputtering nozzle temperature is 90 ℃ in this process, and gluing road material amount is 34.8g, and the speed of shooting material is 4.0g/s; Lower Jiao Dao material amount is 155.0g, and the speed of shooting material is 8.2g/s, penetrates pressure 130KG/cm;
(4) to be 150000kgf, temperature be (87-89) ℃, extruding, and final molding downwards to controlled pressure;
(5) the mould upper and lower mould is opened, finished product ejects die cavity;
(6) take off finished product and put into the forming machine heat treatment.
After the present invention adopts technique scheme, its beneficial effect is: whole technological process reduces with respect to the conventional method processing step, and have and realized that sole is once penetrated by the EVA foam injection molding machine simultaneously by the EVA expanded material of two kinds of different colours and density and obtain, thereby improved production efficiency, also reduced production cost simultaneously.Wherein to divide be once to penetrate acquisition by wear-resisting, anti-tortuous EVA expanded material to the large bottom of this sole, and it is that EVA expanded material strong by toughness, good springiness once penetrates acquisition that middle bottom is divided, and makes it have characteristics ultralight, wear-resisting, anti-complications.
