Specific embodiment
In order to further explain the technical solution of the present invention, being explained in detail below by specific embodiment the present invention
It states.
As shown in Figure 1, it is a kind of moulding process of environment-friendly type sole of the present invention, include the following steps:
1. the TPU material using shore hardness 55A-75A is processed into thickness in the TPU film 10 of 1.0mm-4.0mm；
2. being heated and softened to TPU film 10, it is placed in Packing Machine and carries out plastics sucking moulding, is formed and obtains after cooling
TPU container 20 with bottom wall 21 and side wall 22, the TPU container 20 have upper opening 24,22 shape of the bottom wall 21 and side wall
At cavity 23；Specifically, step 2. in cooling be to realize to carry out shaping TPU container 20 by the way of air-cooled；
3. the EVA waste material or ETPU waste material that will be dried by cleaning are crushed in crusher and form EVA broken material
Or ETPU broken material 31, then be uniformly mixed simultaneously using polyurethane resin glue 32 with aforementioned EVA broken material or ETPU broken material 31
Obtain mixture；
4. 2. TPU container 20 that step is formed is placed in sole forming die, the upper opening 24 of the TPU container 20
Upward, then by step the mixture 3. obtained is added into the cavity 23 of TPU container 20, through obtaining shoes after abundant shaping and demoulding
Indsole；
5. wearing layer 40 is attached at the upper opening 24 of TPU container 20, to form shoes outsole, the TPU container 20
Bottom wall 21 and side wall 22 obtain the finished product of environment-friendly type sole then as the top surface and side of entire sole.
In this way, using the TPU with a thickness of 1.0mm-4.0mm the present invention relates to a kind of moulding process of environment-friendly type sole
Film 10 obtains TPU container 20 later by heating and softening, plastic uptake and cooling and shaping, then polyurethane is added into TPU container 20
Mixture made of resin glue 32 is uniformly mixed with EVA broken material or ETPU broken material 31 obtains midsole after molding,
Wearing layer 40 is formed in 20 upper opening of TPU container, 24 side again, i.e., midsole is turned into use, allows the bottom of TPU container 20
Wall 21 and side wall 22 are then as the top surface and side of entire sole.
Compared with prior art, the present invention at least has the following beneficial effects:
One, TPU film 10 needed for the shore hardness range of well-chosen TPU material of the present invention and molding TPU container 20
Thickness can greatly improve the shaping efficiency of entire sole using plastics sucking moulding technique, and can straighten and, it is ensured that entire shoes
The fine quality of indsole.
Two, the primary raw material that the present invention uses is EVA waste material or ETPU waste material, after being worn by people
The loose woman thrown away as rubbish or rotten shoes also achieve resource while protecting environment it is thus achieved that garbage reclamation utilizes
Secondary use.
Preferably, in the present embodiment, the TPU film 10 of the 1.0mm-4.0mm is transparent configuration.In this way, of the invention
The environment-friendly type sole of formation using transparent TPU film 10 as outer pellicle, inner core be then using polyurethane resin glue 32 with
The mixture of EVA broken material or ETPU broken material so not only has air-cushion type appearance, but also passes through TPU film 10
The cohesion that outer cladding is formed, then the high resiliency for mixing glue 32 and broken material itself can subtract with more more indsole
Shock stability.
Further, die cavity is configured in the Packing Machine, the die cavity has been respectively formed on several thoroughly in bottom surface and side
Stomata, each air hole are connected to the vacuum pump gas circuit in Packing Machine.
Step 4. in abundant molding refer in baking oven under the action of keep molding die to be constantly in 50 DEG C to allow EVA
Waste material or ETPU waste material can solidify with polyurethane resin glue 32 to be connected, which carries out mold to heat and keep mould always
Tool is constantly in 50 DEG C.
As a kind of preferably scheme, the volume ratio of the EVA waste material and polyurethane resin glue 32 is 1:1-6:4.Together
Sample, the volume ratio of the ETPU waste material and polyurethane resin glue 32 is 1:1-6:4.
Above-described embodiment and schema and non-limiting product form and style of the invention, any technical field it is common
The appropriate changes or modifications that technical staff does it all should be regarded as not departing from patent category of the invention.
