[0028] In the present utility model, a mold having a folding basket main body forming cavity 4, four folding basket side plate connecting leg forming cavities 6, and a folding basket side plate connecting leg forming cavity 6 can injection mold a folding basket product without side plates and a cover body. The insert interchangeable folding basket handle forming assemblies 8 can form handrails on the folding basket product, and the insert interchangeable design can produce folding basket products of the same model with different-shaped handles by replacing the interchangeable inserts 9 with folding basket handle forming cavities 10 of different shapes in cooperation with the original mold, with low production costs;

[0029] Secondly, the inclined guiding inner core pulling assembly 5 can achieve internal core pulling after the product is injection molded.

[0030] Specifically, the insert interchangeable folding basket handle forming assembly 8 includes an interchangeable insert 9 connected to the inclined side insert 3 through a translation driving assembly. A folding basket handle forming cavity 10 connected to the folding basket main body forming cavity 4 is provided on the interchangeable insert 9. The translation driving assembly includes a driver mounting plate 11 detachably fixed to the inclined side insert 3 through a plurality of bolts. A translation driver 12 is fixedly connected to the driver mounting plate 11. The end of the output shaft of the translation driver 12 is fixedly connected to an insert connecting plate, and the insert connecting plate is fixed to the interchangeable insert 9 through a plurality of bolts. The translation driver 12 is detachably fixed to the inclined side insert 3 through the driver mounting plate, and the translation driver is connected to the interchangeable insert through the insert connecting plate, so that the translation driver and the interchangeable insert can be replaced. The interchangeable insert together with the folding basket handle forming cavity 10 on the interchangeable insert can be replaced, and folding basket products of the same model with different-shaped handles can be produced in cooperation with the original mold, thereby reducing production costs.

[0031] Those skilled in the art should understand that the translation driver can be an oil cylinder, a cylinder, a linear motor, etc.

[0032] Specifically, the inclined guide inner core-pulling assembly 5 includes a bottom plate 13 arranged at the bottom of the lower template 2. A first lifting driver 14 is fixedly connected to the bottom plate 13. The end of the output shaft of the first lifting driver 14 is fixedly connected with a driving block 15. The driving block 15 is connected with a folding basket main body auxiliary forming block 16 which abuts against the lower side of the inner end face of the inclined side insert block 3 through an inclined guide structure.

Two top-out blocks 24 are fixedly connected to the top plate 21 through a plurality of ejector rods 23. The inner ends of the top-out blocks 24 are connected to the folding basket main body forming cavity 4. After mold opening, the top-out driver 22 can drive the top plate to move in a direction perpendicular to the inner end face of the inclined side insert block. The movement of the top plate can drive the two top-out blocks to move through the ejector rods, so as to apply a force to the folding basket main body to eject the folding basket main body from the inclined side insert block.

[0037] Those skilled in the art should understand that the top-out driver can be an oil cylinder, a cylinder or a linear motor, etc.

[0038] The working principle of the utility model is as follows: A mold with a folding basket main body forming cavity 4, four folding basket side plate connecting leg forming cavities 6, and a folding basket side plate connecting leg forming cavity 6 can be used for injection molding a folding basket product without side plates and a cover body. The interchangeable insert type folding basket handle forming assembly 8 can form armrests on the folding basket product. Moreover, the interchangeable insert design can, by replacing the interchangeable insert 9 with different-shaped folding basket handle forming cavities 10, cooperate with the original mold to produce folding basket products of the same model with different-shaped handles, with low production costs. The inclined guide internal core-pulling assembly 5 can achieve internal core-pulling after the product is injection molded.

[0039] The translation driver 12 is detachably fixed on the inclined side insert 3 through a driver mounting plate. The translation driver is connected to the interchangeable insert through an insert connecting plate, enabling the translation driver and the interchangeable insert to be replaced. The interchangeable insert, together with the folding basket handle forming cavity 10 on the interchangeable insert, can be replaced and can cooperate with the original mold to produce folding basket products of the same model with different-shaped handles, thereby reducing production costs.

[0040] After the product is injection molded, the first lifting driver drives the driving block to descend, which can drive the folding basket main body auxiliary forming block 16 to move away from the inner end face of the inclined side insert through the guide groove 17 and the guide block, so that the inner end of the folding basket main body auxiliary forming block 16 can be separated from the folding basket main body forming cavity 4. After the product is injection molded, an external driving mechanism can drive the inclined side insert and the upper template to move upward synchronously, and then the second lifting driver drives the upper template to rise to separate the upper template from the inclined side insert. After mold opening, the ejection driver 22 can drive the top plate to move in a direction perpendicular to the inner end face of the inclined side insert. The movement of the top plate can drive the two ejection blocks to move through the ejector rods, thereby applying a force to the folding basket main body to eject the folding basket main body from the inclined side insert.
