Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-4, EVA sole aluminum die exhaust structure includes a lower die base 10 and an upper die base 20, and is located the sunken die cavity 30 that has the shaping sole in the middle part of the lower die base, the bottom of die cavity has the bottom exhaust micropore 310 that runs through the lower die base, the die base is located the die cavity side and has lateral part exhaust micropore 320, the upper die base has the top exhaust micropore 210 that runs through and can communicate the die cavity, the bottom exhaust micropore runs through the lower die base, the lower die base is located the lower part main exhaust hole 410 that has vertical run through on the body of die cavity side, lower part main exhaust hole 410 and lateral part exhaust micropore 320 intercommunication, the upper die base has the upper part main exhaust hole 420 that can communicate with lower part main exhaust hole and run through the upper die base.

In this embodiment, the exhaust pin 50 is embedded in the upper main exhaust hole or the lower main exhaust hole, the exhaust pin 50 is fastened in the upper main exhaust hole or the lower main exhaust hole, the exhaust pin includes a pin body and an exhaust hole 510 penetrating through the pin body, the exhaust hole can be reduced to ensure the appearance of the product, and the upper main exhaust hole 420 having a larger hole diameter can be formed during processing and then the exhaust pin is embedded.

In this embodiment, the side exhaust micropores are disposed at the periphery of the mold cavity and at the lower portions of the two sides of the mold cavity, the lower portions of the two sides of the mold cavity are provided with the raised mold cavities, the side exhaust micropores are connected with the oblique communication passage 60 of the main exhaust hole at the lower portion, and the oblique communication passage 60 is arranged to facilitate the smooth gas exhaust and prevent the occurrence of delay at the corner.

In practical design, the bottom air outlet micro-holes 310 are located at the edge of the sole profile, and generally, in order to reduce the construction cost, the lower die holder is correspondingly provided with a plurality of die cavities.

In this embodiment, one end of the upper die holder and one end of the lower die holder are hinged through a bolt.

Because the outer surfaces of the upper die base and the lower die base are respectively provided with the bottom exhaust micropore, the top exhaust micropore, the upper main exhaust hole and the lower main exhaust hole which are attached to the frame during installation, the air can be smoothly exhausted, in order to ensure that the upper die base and the lower die base are provided with the plurality of criss-cross exhaust grooves 50, the bottom exhaust micropore, the top exhaust micropore, the upper main exhaust hole and the lower main exhaust hole can be communicated with the exhaust grooves, and the exhaust grooves 70 are used for exhausting the bottom exhaust micropore, the top exhaust micropore, the upper main exhaust hole and the lower main exhaust hole to the outside.
