[0021] Refer to Figure 2 , a lower cushion block 414 matched with the die cavity 201 is installed on the demoulding bottom plate 4. The upper end of the lower cushion block 414 is kept inside the die cavity 201. Z-shaped support plates 401 are installed on both sides of the demoulding bottom plate 4. The lower end of the Z-shaped support plate 401 is connected to the demoulding bottom plate 4, and a through hole 402 matched with the upper die pull rod 302 is formed at the upper end. Pull rod locking mechanisms 403 are installed on both sides of the through hole 402, an unlocking mechanism 404 is installed at the rear end of the pull rod locking mechanism 403, and a limit locking tongue 405 is installed on the Z-shaped support plate 401 below the pull rod locking mechanism 403.

[0022] Limit push rods 202 are slidably installed on both sides of the lower die 2. Limit springs 203 are installed on the limit push rods 202 and openings matched with the limit locking tongues 405 are formed. One end of the limit spring 203 is connected to the limit push rod 202, and the other end is connected to the lower die 2.

[0023] Refer to Figure 3, the drawbar locking mechanism 403 includes a locking housing 406. A drawbar lock tongue 407 is installed inside the locking housing 406. A telescopic rod 408 is installed at the rear end of the drawbar lock tongue 407. A locking spring 409 is installed on the telescopic rod 408. The end of the telescopic rod 408 penetrates through the locking housing 406 and an unlocking block 410 is installed thereon; the unlocking mechanism 404 includes an unlocking bracket 411. An unlocking rod 412 is installed on the unlocking bracket 411. An unlocking spring 413 is installed on the unlocking rod 412. A wedge block is provided at the lower end of the unlocking rod 412. An inclined surface matching the wedge block is provided on the unlocking block 410.

[0024] For the convenience of understanding the present invention, the working principle of the present solution will be described in detail below in conjunction with Figure 1 - Figure 4 :

[0025] The lower die base 1 is slidably installed below the pressing device 6. A driving mechanism (not shown in the figure) is installed on the pressing device 6 to drive the lower die base 1 to move;

[0026] Before working, the limit lock tongue 405 is located below the limit push rod 202. At this time, the lower cushion block 414 is at the lowest position in the die cavity 201. The upper die base 3 moves to the lower part of the feeding mechanism 5 to inject concrete material, and then moves to below the pressing device 6. The pressing device 6 drives the upper die base 3 to descend, and the upper pressing block 303 enters the die cavity 201 to extrude the concrete material therein into a mold. During the descending process of the upper die base 3, the upper die drawbar 302 is inserted into the through hole 402. After the solid brick is extruded and formed, during the ascending process of the upper die base 3, the drawbar lock tongue 407 is inserted into the bayonet of the upper die drawbar 302, thereby driving the demoulding bottom plate 4 to rise to eject the solid brick from the die cavity 201, facilitating the grasping by the transfer mechanism;

[0027] During the ascending process of the demoulding bottom plate 4, the upper inclined surface of the limit lock tongue 405 contacts the side of the limit push rod 202 and pushes it to retract. After the limit lock tongue 405 passes over the limit push rod 202, it pops out, thereby keeping the limit lock tongue 405 above the limit push rod 202. As the demoulding bottom plate 4 continues to rise, the unlocking rod 412 contacts the top of the lower die 2 and drives the drawbar lock tongue 407 to move through the unlocking block 410 to disengage it from the bayonet of the upper die drawbar 302. At this time, the upper end of the solid brick protrudes from the lower die 2. The driving mechanism pushes the lower die base 1 out of the pressing device 6 to facilitate the grasping and feeding by the feeding mechanism;

[0028] After the feeding is completed, the driving mechanism drives the lower die base 1 to move to the lower part of the feeding mechanism 5. A stop block (not shown in the figure) opposite to the limit push rod 202 is installed below the feeding mechanism 5. The stop block pushes the limit push rod 202 to move so that the opening thereon is aligned with the limit lock tongue 405. The return spring 102 pulls the demoulding bottom plate 4 to descend to reset it, and the feeding mechanism 5 pours concrete material into the die cavity 201.

[0029] The specific implementation manners of the present utility model described above do not constitute a limitation on the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model shall be included within the protection scope of the claims of the present utility model.
