Abstract
The present invention provides a sole forming process and a special mold. The process includes the following steps: 1) mold heating, 2) material feeding, 3) mold matching and vacuumizing and 4) mold cooling. After the cooling, the finished product can be taken out of the mold. The mold consists of an upper mold and a lower mold; the upper mold consists of an upper cover plate and an upper cover with an internal kernel; the lower mold consists of a lower cover and a lower cover plate; a cavity for holding the sole is formed between the lower cover and the internal kernel; the inside of the upper mold and the lower mold is respectively provided with a cooling pipeline; the cooling pipeline is communicated with a cooling circulation pipeline outside. The present invention has the characteristics of smooth appearance of finished products, quick mold cooling speed, high production efficiency, low labor intensity of operators and less labors. The process that the appearance of the finished product is vacuumized in the mold gives up the way of making gas holes on the mold, prevents the mold from deformation and fracture and increases the service life of the mold. At the same time, the circulation cooling way in the mold has good stability and the water can be recycled, thus reducing the water use and saving the production cost.
Description
Technical field
The present invention relates to a kind of Sole moulding technology, specifically a kind of sole molding process and particular manufacturing craft thereof.
Background technology
Existing sole molding process at first is put into mould on the heater and heats, and material for sole of shoe is put into die for molding after reaching suitable temperature, goes to the cooling board then and waters the pouring mold cools down with normal-temperature water, and back die sinking taking-up finished product is finished in cooling, machines.This process using electric hot plate heating, in order to eliminate material for sole of shoe displacement after the thermal expansion and be subjected to the resistance of gas, on mould, have venthole, finished surface after the moulding is at venthole position outlet small embossment, influence outward appearance, sometimes cause moulding bad because venthole is blocked, become waste product.Adopt normal-temperature water that mold shell is cooled off in cooling procedure, cooling velocity is slow, and efficient is low, and also very big to the consumption of water.
Summary of the invention
One of technical problem that will solve of the present invention is to provide a kind of Sole moulding processing technology:
In order to solve the problems of the technologies described above, the present invention takes following mode to realize:
A kind of sole molding process, this technology performing step is:
1) mold heated, 2) blowing, 3) the mould matched moulds, find time 4) mold cools down, can take away mould after cooling is finished and go out finished product.Wherein, mold heated temperature to 130～170 degree centigrade; The mould inside evacuated time is 3～7 minutes; Mould adopts the normal-temperature water cooling, and be 1～3 minute cool time.
One of another technical problem that will solve of the present invention is to provide a kind of sole molding process particular manufacturing craft, and this technical problem takes following mode to realize:
A kind of mould structure, comprise upper die and lower die, this patrix comprises the loam cake cover plate and contains the loam cake of interior benevolence, this counterdie comprises lower cover and lower cover cover plate, be formed with the die cavity that holds sole between lower cover and the interior benevolence, all offer cooling pipe in the described upper die and lower die, cooling pipe is communicated with the external refrigeration circulation line.
Wherein, the cooling pipe in the upper die and lower die is connected mutually and is communicated with the external refrigeration circulation line.And cooling pipe is the S font and is distributed in the upper die and lower die.In upper die and lower die, also be provided with the cooling slotted eye that is used to connect external refrigeration circulation line and cooling pipe.Also offer the emptying aperture that is communicated with die cavity at upper die and lower die.
Finished product flat appearance of the present invention, mold cools down speed is fast, the production efficiency height, operator's labour intensity is low, and required labour is few, the technology that the finished product outward appearance is found time in mould, given up the mode in hole of on mould, inflating, not only make the calm hole of finished product, also do not make mould yielding and break, increased the service life of mould; Simultaneously, owing to adopt hydronic mode in mould, good stability, water can be recycled, and has reduced water, has saved production cost.
Description of drawings
Accompanying drawing 1 is an embodiment of the invention sole molding process flow chart;
Accompanying drawing 2 is a present embodiment mould cross-sectional view;
Accompanying drawing 3 is a present embodiment die face visual angle structural representation.
The specific embodiment
Describe the present invention for the ease of it will be appreciated by those skilled in the art that below in conjunction with embodiment and accompanying drawing:
Be the flow chart of embodiment of the invention sole molding process as shown in Figure 1, this technology performing step is: 1) mold heated, 2) blowing, 3) the mould matched moulds, find time 4) mold cools down, can take away mould after cooling is finished and go out finished product.Wherein, mold heated temperature to 130～170 degree centigrade; The mould inside evacuated time is 3～7 minutes; Mould adopts the normal-temperature water cooling, and be 1～3 minute cool time.
The sole surface of this technological forming is smooth, attractive in appearance, and the speed of cooling is also very fast greatly, and is convenient during forming operation, quick, and also raising greatly of cooling velocity, has greatly improved production efficiency.
The mould that this programme adopted comprises patrix 2, counterdie 3, shown in accompanying drawing 2,3.This patrix comprises loam cake cover plate 22 and contains the loam cake 21 of interior benevolence 24, counterdie 3 comprises lower cover 31 and lower cover cover plate 32, also be fixed with handle 4 on described loam cake cover plate 22 and the lower cover cover plate 32, handle 4 is used for mould is fixed on the work board, at patrix 2, all offer cooling pipe 7 in the counterdie 3, cooling pipe 7 is communicated with the external refrigeration circulation line, be formed with the die cavity 8 that holds sole between lower cover 31 and the interior benevolence 24, when mould heat be heated after, the method matched moulds moulding that employing is found time in mould, make EVA (ethene-acetate ethylene copolymer) material foaming back displacement after the thermal expansion not be subjected to the resistance of gas, give up the mode in hole of on mould, inflating fully, make the calm hole of footwear mould of moulding, embodied attractive in appearancely, also increased service life of mould.
Simultaneously, also offer the emptying aperture 5 that is communicated with die cavity 8 at patrix 2, counterdie 3.
The mould of this structure has been eliminated the influence of existing mold wind hole to moulding sole surface outward appearance, operates and cools off convenient.
More than for the preferable implementation of the present invention, need to prove, do not breaking away under the inventive concept prerequisite of the present invention any conspicuous replacement all within protection domain of the present invention.
