Description
Technical field
The utility model relates to the sport footwears that a kind of sport footwear more particularly to a kind of sole embed 3D printing module.
Background technique
Sport footwear production be a kind of technology-intensive type production chain, be related to design, CAD modeling, wooden model carve, die trial,
Multiple links such as die sinking, modification, production, not only the development & production period is longer, and technology is complicated, and cannot exclude artificial work
Industry, therefore, shoe industry are referred to as one of the industry for being most difficult to realize automation.
Current most of common sport footwear all uses the sole comprising foamed material.For example, by ethylene-vinyl acetate
(EVA) or foam made of polyurethane (PU) can provide outstanding cushion performance for the load occurred in sole, thus by with
Make the typical material of the midsole between the area sole Nei Di and outer bottom area.
Foot bottom stress situation is complicated during exercise for human body, vola different zones meet in different motion embody it is different
Plantar pressure and motion feature.Such as in the support phase of a simple gait cycle, initial initially lands the phase, half sole
It does not stress, heel portion pressure is gradually increased, especially the region below calcaneum, and centered on this region, pressure is in ladder around
Reduce to degree formula；And with the Forward of gravity center of human body, each areal pressure of heel portion starts to be gradually reduced, arch of foot, half sole in succession
The pressure of ground, arch of foot and half sole starts to increase, and Center of Pressure is transitioned on the outside of arch of foot from heel portion and is moved to half sole；And it arrives
The later period is supported, heel starts liftoff, and heel portion pressure starts to reduce, and half sole pressure starts to reach to peak value, especially first, second
Areal pressure increase below metatarsal is the most obvious, and centered on this region, formula reduces pressure in gradient around；It is pushing away
Phase, heel portion do not stress, and entire foot starts to push away ground, and half sole pressure also starts to be gradually reduced, and support phase terminates.Thus
The complexity of foot stress and motion feature in visible movement, based on simplest gait cycle, comprehensive study is variant
The crowd of sports events motion feature and different motion feature analyzes its foot movement feature, by setting in movement midsole
Enter to meet the footwear sole construction of project movement characteristic and user's motion feature, it is anti-that most reasonable mechanics can be provided for user
Feedback, supports the completion of its technical movements.Different footwear sole constructions are because of material, form and the difference in movement midsole distribution
And embody different characteristics.By the way that various material, variform are combined, the middle bear building-up of available a variety of mechanical characteristics
The energy in movement can be absorbed as shock-damping structure in structure, some of them；Other can be absorbed the energy in movement and will
It feeds back to human body, as rebound structure；In addition to this there are also the structure that some performances fall between, these structures are closed
Reason ground, which applies to movement midsole, can make sole more be bonded human body requirements and motion feature.
3D printing technique is also known as increases material manufacturing technology, different from previous manufacture, and 3D printing is with 3D mathematical model
Based on, object structures are constructed by layer-by-layer printing, the process for eliminating numerous complicated in industrial product forming process,
It only needs 3D mathematical model importing 3D printer, after the completion of being printed by 3D printer, can be obtained by simply post-processing
One 3D printing finished product.
Compared to traditional mold forming technique, 3D printing technique (i.e. increases material manufacturing technology) can not be fettered by mold, be beaten
Any shape is printed, and has the period short, feature with high accuracy.For cooperative movement person's technical movements, conventional motion shoes are relied on
The product that multiple functional components could be completed, 3D printing shoes can be realized by the moulding of parameter change sport footwear and Density Distribution.
The advantages of 3D printing shoes: first is that saving material, do not have to reject leftover pieces, stock utilization is improved, by abandoning life
Producing line and reduce costs；Second is that can accomplish very high precision and complexity, in addition to setting on appearance curve can be shown
Meter, it is no longer necessary to which traditional cutter, fixture and lathe or any mold can be generated directly from computer graphics data any
The part of shape, it greatly reduces assembling cost, it even can challenge mass production method.
In the prior art, universal in industrial product of 3D printing technique is limited by material and cost at present, and 3D printing is former
The current limitation of material is larger, it is common to use printed material only have TPU (thermoplastic), nylon, resin, rubber, metal powder
The a few materials such as end, in addition current 3D printing high expensive, therefore in practical applications, 3D printing technique can not also substitute completely
Traditional manufacturing technology.Especially in shoe industry, movement midsole uses foamed material, the foaming light-weight, elasticity is good mostly
Material can provide good comfort for vola, and the weight and resilience of 3D printing product all can not be with traditional foamed material phases
Than this is to restrict the main reason for 3D printing sport footwear is widely applied in shoe industry.
