[0025] This specific embodiment is an easy demoulding mold, and its structural schematic diagram is as follows Figure 1-Figure 5 As shown, the mold includes a bottom mold 1, a liftable top mold 2 is arranged on the top of the bottom mold 1, a U-shaped frame 3 is fixed at one end of the bottom mold 1, hydraulic cylinders 4 are fixed at both ends of the U-shaped frame 3, the output end of the hydraulic cylinder 4 is fixedly connected to the top mold 2, and a demoulding mechanism is arranged inside the top mold 2;

[0026] The demoulding mechanism includes two transverse polished rods 15, both of which are fixed inside the top mold 2, and both ends of the outer sides of the transverse polished rods 15 are slidably connected with rectangular moving blocks 9, the top of the rectangular moving block 9 is rotatably connected with an oblique rotating column 10, the top of the oblique rotating column 10 is rotatably connected with a top lifting block 11, the top of the top lifting block 11 is fixed with a vertical sliding column 12, and the top of the vertical sliding column 12 is fixed with a lifting baffle 7;

[0027] Rigid springs 13 are provided between the top mold 2 and the rectangular moving block 9 and between the two rectangular moving blocks 9 and on the outside of the transverse polished rod 15. An L-shaped connecting block 14 is fixed at one end of the rectangular moving block 9, and a bottom supporting block 8 is fixed at the bottom of the L-shaped connecting block 14.

[0028] A circular through hole is provided inside the rectangular moving block 9, and the rectangular moving block 9 is slidably connected to the transverse light rod 15 through the circular through hole. The rectangular moving block 9 can slide on the outside of the transverse light rod 15 through the circular through hole.

[0029] A transverse sliding groove is provided inside the top mold 2, and the L-shaped connecting block 14 is located inside the transverse sliding groove and is slidably connected with the top mold 2 through the setting of the transverse sliding groove. Through the setting of the transverse sliding groove, the L-shaped connecting block 14 can move inside the top mold 2. When the L-shaped connecting block 14 moves, the bottom supporting block 8 can move at the bottom of the top mold 2, thereby allowing the bottom supporting block 8 to release the workpiece inside the top mold 2;

[0030] Both sides of the top of the bottom support block 8 are fixed with transverse limit columns 82, which are located inside the top mold 2 and are slidably connected to the top mold 2. Both sides of one end of the bottom support block 8 are fixed with vertical limit columns 81, which are located inside the bottom mold 1 and are slidably connected to the bottom mold 1.

[0031] A transverse limiting groove adapted to the transverse limiting column 82 is provided inside the top mold 2, and the top mold 2 and the transverse limiting column 82 are slidably connected via the transverse limiting groove. A vertical limiting groove adapted to the vertical limiting column 81 is provided inside the bottom mold 1, and the bottom mold 1 and the vertical limiting column 81 are slidably connected via the vertical limiting groove. By setting the transverse limiting groove, the transverse limiting column 82 can slide at the bottom of the top mold 2, thereby guiding the moving trajectory of the bottom support block 8. By setting the vertical limiting groove, the vertical limiting column 81 can be vertically lifted and lowered inside the bottom mold 1, thereby limiting the moving trajectory of the top mold 2 at the top of the bottom mold 1.

[0032] In addition, a vertical mounting column 5 is fixed at the middle position inside the U-shaped frame 3, and a top baffle 6 adapted to the lifting baffle 7 is fixed to the bottom of the vertical mounting column 5, so that when the hydraulic cylinder 4 is operating, the lifting baffle 7 can be raised and lowered so that the lifting baffle 7 and the top baffle 6 are in contact with each other.

[0033] Working principle: When demolding is required, the operation of the hydraulic cylinder 4 enables the top mold 2 to be lifted vertically. The lifting of the top mold 2 enables the lifting baffle 7 to be lifted synchronously. When the lifting baffle 7 is in contact with the top baffle 6, the top mold 2 continues to lift. Through the setting of the vertical sliding column 12, the top lifting block 11 can be lowered inside the top mold 2. The descent of the top lifting block 11 enables the rectangular moving block 9 to slide inside the transverse light rod 15 through the oblique rotating column 10. The sliding of the rectangular moving block 9 causes the rigid spring 13 to undergo a phase change in force. The movement of the two rectangular moving blocks 9 enables the bottom support block 8 to move at the bottom of the top mold 2 through the L-shaped connecting block 14. The movement of the bottom support block 8 can remove the restriction on the workpiece to facilitate demolding.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
