[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Figure 1-10As shown, a transport airbag mold structure includes an upper mold 1 and a lower mold 2 arranged correspondingly. After the upper mold 1 and lower mold 2 are closed, they form a cavity 3 corresponding to the semi-finished transport airbag and an air inlet 4 connected to the cavity 3. The upper mold 1 is provided with an upper fixing component for connecting to the upper fixing plate of the vulcanizing machine, and the lower mold 2 is provided with a lower fixing component for connecting to the lower fixing plate of the vulcanizing machine. A first cavity 3 can be provided on the lower surface of the upper mold 1; a second cavity 3 can be provided on the upper surface of the lower mold 2. After the upper mold 1 and lower mold 2 are closed, the first cavity 3 and the second cavity 3 together form cavity 3. Alternatively, the lower surface of the upper mold 1 may not have a cavity 3, and may be a planar structure; the lower mold 2 may have a second cavity 3, which, when closed, forms cavity 3. These are all within the protection scope of this utility model. The dimensions and thickness of the cavity 3 correspond to the semi-finished transport airbag. In this invention, the semi-finished transport airbag is set within the transport airbag mold structure and vulcanized on a flat vulcanizing machine. The structure is simple and low-cost, achieving the curing of the transport airbag. The rubber material of the semi-finished transport airbag is transformed from raw rubber to cured rubber, fixing its shape. An air inlet communicating with the internal air chamber of the semi-finished transport airbag is provided on the semi-finished transport airbag. Therefore, the mold needs a corresponding air inlet 4. The upper fixing component and the lower fixing component can be existing fixing structures, such as the upper mold 1 and lower mold 2 being fixed to the upper fixing plate or the lower fixing plate respectively by bolts.

[0027] A U-shaped groove 40 is provided on the lower surface of the upper mold 1; one end of the U-shaped groove 40 extends to the edge of the upper mold 1, and the other end extends to a position communicating with the cavity 3 and is fixedly provided with an upper pressure block 41; a U-shaped groove 42 is provided at a corresponding position on the upper surface of the lower mold 2; one end of the U-shaped groove 42 extends to the edge of the lower mold 2, and the other end extends to a position communicating with the cavity 3 and is fixedly provided with a lower pressure block 43; half a through hole is provided on the upper pressure block 41 and the lower pressure block 43 respectively; after the mold is closed, the middle of the upper pressure block 41 and the lower pressure block 43 forms a through hole as an air inlet 4. The half through hole on the upper pressure block 41 and the lower pressure block 43 can be split in half or other distribution methods, as long as it forms an air inlet 4. The shape of the through hole is determined according to the shape of the air inlet 4. In the structure shown in the attached figure, the through hole is a three-stage stepped hole, with the middle hole having the smallest diameter, the outermost hole having the largest diameter, and the diameter of the hole closest to the cavity 3 being between the two. Other structures are also possible. The upper pressure block 41 is disposed on the upper mold 1 along the U-shaped groove 40 and can be detachably fixed in the U-shaped groove 40 of the upper mold 1 by bolts. The lower pressure block 43 is installed along the U-shaped groove 42 and is connected to the lower mold 2 by bolts. The U-shaped groove 42 facilitates the installation of the upper pressure block 41 and the lower pressure block 43.

[0028] The upper pressure block 41 has two sides, left and right, with gradually converging downward slopes; the lower pressure block 43 is positioned above half of the through hole and has corresponding slopes on the two sides of the upper pressure block 41; the lower pressure block 43 and the lower pressure block 43 engage with each other via these slopes. (This sloped engagement effectively positions the upper pressure block 41 and the lower pressure block 43, facilitating the positioning of the air inlet 4. The two slopes of the lower pressure block 43 gradually separate upwards, engaging with the two sides of the upper pressure block 41.)

[0029] The lower mold 2 is provided with a handle storage channel 6 corresponding to the handle position of the semi-finished transport airbag, which communicates with the cavity 3. The handle storage channel 6 includes a storage groove 61 on the lower mold 2. One side of the storage groove 61 extends to the edge of the lower mold 2, and the other side communicates with the cavity 3 through two handle channels 62. The depth of the handle channel 62 is less than the depth of the storage groove 61. Many semi-finished transport airbags are provided with multiple handles, and the corresponding positions of the mold need to be provided with handle storage channels 6. The shape and number of handle storage channels 6 are determined according to actual needs. In the attached figure, 4 to 8 handle storage channels 6 can be provided.

[0030] The upper surface of the lower mold 2 is provided with a glue discharge system, which includes a circumferential glue discharge groove 7 located on the outer ring of the cavity 3, and a radial glue discharge groove 8 arranged outward from the circumferential glue discharge groove 7. The end of the radial glue discharge groove 8 extends to the edge of the lower mold 2 or extends to a height of the lower mold 2 lower than the edge plane of the radial glue discharge groove. The edge plane refers to a plane close to the edge of the lower mold 2. The edge of the lower mold 2 refers to the edge line of the lower mold 2. There is a certain distance between the circumferential glue discharge groove 7 and the cavity 3, which can be 0.5 to 2 mm. The shape of the circumferential glue discharge groove 7 can be elliptical, and the radial glue discharge grooves 8 are arranged in parallel and one end is connected to the circumferential glue discharge groove 7.

[0031] The upper fixing component and the lower fixing component are respectively fixed feet 5 along the periphery of the upper mold 1 and the lower mold 2; the feet 5 are detachably connected to the upper fixing plate or the lower fixing plate by bolts. The feet 5 are provided with elongated holes. The upper fixing plate and the lower fixing plate of the flat vulcanizing machine are respectively provided with fixing holes, and bolts are used for fixing after passing through the feet 5 and the fixing holes. Several feet 5 are respectively provided on both sides of the upper mold 1 and both sides of the lower mold 2. The feet 5 can be bolted to the upper mold 1 and the lower mold 2, and the feet 5 are inverted Z-shaped or inverted L-shaped.

[0032] The upper mold 1 has guide posts 11 arranged circumferentially, and the lower mold 2 has guide holes 12 corresponding to the positions of the guide posts 11. The guide posts 11 and guide holes 12 cooperate to guide the upper mold 1 and the lower mold 2. The guide posts 11 and the upper mold 1 can be fitted with stepped holes; guide sleeves can be provided between the guide holes 12, engaging with the guide posts 11. Alternatively, the arrangement can be reversed, with guide sleeves on the upper mold 1 and guide posts 11 on the lower mold 2.

[0033] At least one of the upper mold 1 or lower mold 2 has an opening 9 at its edge, and the lower surface of the upper mold 1 and the upper surface of the lower mold 2 are separated at the opening 9. At least one long lifting lug 10 is provided on each of the front and rear sides of the lower mold 2. The long lifting lug 10 is connected to the lower mold 2 by a threaded connection. The upper mold 1 has at least two lifting holes 13. The opening 10 can be located at the front and rear edges of the lower mold 2, and its shape can be a groove. Alternatively, it can be located at the edge of the upper mold 1. The long lifting lug 10 is divided into five segments: the first segment is threaded and connected to the lower mold 2; the second and fourth segments are straight; the third segment is oblique; and the fifth segment is stepped, with each cross-section being circular. The upper mold 1 and lower mold 2 are lifted using the long lifting lug 10 and the lifting holes 13. Two long lifting lugs 10 can be provided on each side of the lower mold 2, for a total of four long lifting lugs 10.

[0034] The upper mold 1 and the lower mold 2 are rectangular plates; the upper surface of the upper mold 1, corresponding to the cavity 3, is a plane, and the cavity 3 is located on the upper surface of the lower mold 2; the top view of the cavity 3 is a rectangle with four rounded corners; the air inlet 4 is located at a 45-degree angle at the corner. The U-shaped groove 40 and U-shaped channel 42 are respectively located at a 45-degree angle, but they can also be located in other positions. In this invention, the cavity 3, the handle storage channel 6, and the glue discharge system are all located in the lower mold 2, making the upper mold 1 simple in structure and easy to manufacture, reducing the fitting accuracy of the upper mold 1 and the lower mold 2 and the required manufacturing accuracy.

[0035] In practice: the upper pressure block 41 is fixed to the upper mold 1 with bolts, and the lower pressure block 43 is fixed to the lower mold 2. The long lifting lugs 10 are installed on the front and rear sides of the lower mold 2 via threaded connections. The upper mold 1 and the lower mold 2 are closed by guide pillars 11 and guide sleeves. The closed upper and lower molds are transferred to the flat vulcanizing machine.
