It is further preferred that by being clamped or being threadedly coupled or be embedded between the vacuumizing joint and the gas channel
Mode be fixedly linked.
In the present invention, the cavity is set to the position that the rear mold corresponds to die joint, the air drain one at
Type corresponds to the position of die joint in the preceding mould, and the gas channel is shaped in the rear mold.
Preferably, it is additionally provided with a gum-injecting port being connected with the cavity on the preceding mould.
The beneficial effects of the utility model：The Vacuuming structure of the utility model, including preceding mould and rear mold, the preceding mould
And/or rear mold is provided with a cavity at the position of corresponding die joint, the cavity is connected with for by its internal trapped gas extraction
Gas suction device, such the technical program can be extracted out trapped gas in cavity by gas suction device, and cavity is connect
Nearly vacuum state avoids occurring due to having trapped gas in cavity, the case where to cause sizing material to be unevenly distributed in cavity, user
Experience sense is good, and application prospect is wide, to significantly enhance the market competitiveness of manufacturer.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model；
