Description
Technical field
The utility model is related to shoe sole production apparatus fields, and in particular to be a kind of molding of PU and TPU composite soles
Equipment.
Background technology
PU is the abbreviation of English poly urethane, and chemical Chinese is polyurethane, since its flexibility is good and 3D is slow
The good feature of damping effect is rushed, a kind of common midsole material is had become, but since it contacts meeting later with air
Slowly influence its quality, thus be typically necessary its outer surface carry out one layer processing, such as using at present through frequently with spray painting
Processing, this undoubtedly brings larger production pressure for environmental protection measure increasingly strict at present to enterprise, is based on this application
People proposes that the mode of the attached last layer TPU film outside PU midsoles, as described TPU film can not only play baffle space
Effect, and due to the quality of TPU film itself, the class of entire product is also greatly improved, furthermore PU and TPU inherently belong to
In polyurethane material, the two amalgamation is also good, and the product quality of formation is preferable.
But major producer is on the problem of TPU film stabilization is formed in PU midsoles bottom and lateral margin currently on the market,
More in-depth study was not carried out, the solution of complete set was not obtained yet, the applicant is based on this skill
Art problem is furtherd investigate, though there is this case generation.
Utility model content
The main purpose of the utility model is to provide a kind of PU and TPU composite soles formers, can be high-quality
Amount realizes TPU film composite molding outside PU midsoles, it is ensured that the quality of product.
In order to achieve the above objectives, the solution of the utility model is：
A kind of PU and TPU composite soles former, wherein thin including upper die and lower die, vacuum device and TPU
Film heating mechanism, the lower die have bottom wall and a side wall, and the bottom wall and side wall have been respectively formed on several through holes, it is described on
Cavity is formed between mould and lower die, several described through holes communicate cavity and vacuum device gas circuit, in the upper mold
It is additionally provided with feed inlet, the TPU film heating mechanism is for heating the TPU film in lower die.
Further, the TPU film heating mechanism is infrared heating equipment.
Further, the former further includes applying stressed pressing mechanism to upper mold.
Further, the vacuum device includes vacuum generator and the air-flow adapter for being set in lower die periphery, institute
It states air-flow adapter lower end with vacuum generator to be connected, the air-flow adapter is also connected with several through holes.
Further, the thickness for being located at TPU film in lower mold is 0.06-0.3mm.
With the above structure, the utility model is related to a kind of PU and TPU composite soles former, first with
TPU film heating mechanism heats TPU film, and TPU film is made to soften；Recycle vacuum device by TPU film tightly
Ground is adsorbed on the bottom wall and side wall of lower die；The PU material that A/B expects TPU film is added to by the feed inlet in upper mold again to be formed
Inner cavity in, using can be obtained PU and TPU composite soles after molding.
Since PU and TPU belong to polyurethane material, the two has preferable compatibility, so that knot between the two
Closing can be close enough, meet the needs of shoes, and can be played positioned at external TPU film and separate PU midsoles and air
Effect, it is ensured that the high life of PU midsoles, and due to the beautiful air of TPU film, also greatly improve the shelves of entire sole
It is secondary.

Specific implementation mode
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
As shown in Figure 1, its be the utility model is related to a kind of PU and TPU composite soles former, including upper mold
21, lower die 22, vacuum device and TPU film heating mechanism 24.
The lower die 22 has bottom wall 221 and side wall 222, and the bottom wall 221 and side wall 222 have been respectively formed on several and have passed through
Through-hole 223 is formed with cavity 25 between the upper mold 21 and lower die 22, several described through holes 223 are by cavity 25 and take out true
Empty mechanism gas circuit communicates, and feed inlet 211 is additionally provided in the upper mold 21, and the TPU film heating mechanism 24 is used for being located at
TPU film 11 in lower die 22 is heated.As a kind of specific embodiment, the TPU film heating mechanism 24 is red
Outside line heating equipment.
In this way, the utility model is related to a kind of PU and TPU composite soles former, heated first with TPU film
Mechanism 24 heats TPU film 11, and TPU film 11 is made to soften；Vacuum device is recycled tightly to inhale TPU film 11
It is attached on the bottom wall 221 and side wall 222 of lower die 22；The PU material that A/B expects are added to by the feed inlet 211 in upper mold 21 again
In the inner cavity that TPU film 11 is formed, using can be obtained PU and TPU composite soles after molding.
Since PU and TPU belong to polyurethane material, the two has preferable compatibility, so that knot between the two
Closing can be close enough, meet the needs of shoes, and positioned at external TPU film 11 can play by PU midsoles 12 and air every
The effect opened, as shown in Figure 1, PU midsoles 12 are located at the inside of TPU film 11, it is ensured that the high life of PU midsoles 12, Er Qieyou
In the beautiful air of TPU film 11, the class of entire sole is also greatly improved.
As the prior art, in the forming process of PU midsoles 12, the former further includes applying to upper mold 21
The pressing mechanism of pressure, the concrete structure just no longer statement in detail for pressing mechanism.
As shown in Fig. 2, the vacuum device includes vacuum generator and the air-flow switching for being set in 22 periphery of lower die
First 23,23 lower end of air-flow adapter is connected with vacuum generator, the air-flow adapter 23 also with several through holes
223 are connected.In order to which TPU film 11 can be particularly well adsorbed on the bottom wall 221 and side wall 222 of lower die 22, it is located at lower die
The thickness of TPU film 11 is preferably 0.06-0.3mm in 22 tools.
