DETAILED DESCRIPTION

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-4 As shown, an automatic demoulding device for brick blanks comprises a workbench 1, a mounting frame 2 is arranged on the upper surface of the workbench 1, a mold frame 3 is slidably connected to the mounting frame 2, vertical plates 4 are arranged on both sides of the mold frame 3, a card slot 5 is arranged on the upper end of the vertical plate 4, a first hydraulic cylinder 6 is arranged on the mounting frame 2, a shell 7 is arranged on the output end of the first hydraulic cylinder 6, a card plate 8 is slidably connected to the two ends of the shell 7, a tightening portion 9 matching the card slot 5 is arranged at the end of the card plate 8, a first spring 10 is arranged inside the shell 7 and between the two card plates 8, a through groove is opened on the card plate 8, a fixing rod 11 matching the through groove is arranged on the mounting frame 2, a protrusion 12 is arranged on the upper end outer surface of the fixing rod 11, a cover plate 13 slidably connected to the mounting frame 2 is arranged below the shell 7, the shell 7 and the cover plate 13 are connected by a second spring 14, an extension rod 15 is symmetrically arranged on the upper surface of the cover plate 13, and a bending block 16 matching the mold frame 3 is arranged at the end of the extension rod 15.

[0018] The through groove on the card plate 8 is in the form of a waist hole. When the abutting portion 9 of the card plate 8 and the card groove 5 at the upper end of the vertical plate 4 abut against each other, the side of the through groove close to the shell 7 contacts the outer surface of the fixing rod 11. At this time, one end of the card plate 8 is still located inside the shell 7 to prevent the shell 7 from losing contact with the card plate 8. In order to further improve the matching stability between the shell 7 and the card plate 8, the two ends of the first spring 10 are respectively fixedly connected to the card plates 8 on both sides of the shell 7. There are 3 groups of first springs 10, and when the abutting portion 9 of the card plate 8 and the card groove 5 at the upper end of the vertical plate 4 abut against each other, the first spring 10 is in a compressed state.

[0019] A chamfer or rounding is provided on the upper end side of the through groove close to the shell 7 to facilitate the protrusion 12 to enter the through groove. When the card plate 8 rises, the protrusion 12 can enter the through groove, so that the card plate 8 moves into the shell 7, further compressing the first spring 10 in the shell 7 until the clamping portion 9 of the card plate 8 is disengaged from the card groove 5 at the upper end of the vertical plate 4. At this time, the card plate 8 stops rising, and under the action of gravity, the mold frame 3 moves downward. At the same time, the mold frame 3 and the cover plate 13 are connected to the mounting frame 2 through a guide plate, which can ensure that the mold frame 3 can move downward perpendicular to the upper surface of the workbench 1.

[0020] When the mold frame 3 is placed on the workbench 1, the cover plate 13 is moved upwards by the first hydraulic cylinder 6, and an appropriate amount of brick raw material is put into the mold frame 3 through the upper side of the mold frame 3, and then the output end of the first hydraulic cylinder 6 is controlled to extend to drive the shell 7 to move downward. The shell 7 pushes the cover plate 13 downward through the second spring 14, and the guide plate on the side of the cover plate 13 can ensure that the cover plate 13 can move downward perpendicular to the workbench 1, and the cover plate 13 can enter the upper end opening of the mold frame 3, and by continuously squeezing the second spring 14, the cover plate 13 can continuously squeeze the brick raw material in the mold frame 3 until the brick is formed. At this time, the abutting portion 9 on the clamping plate 8 is located below the clamping groove 5 on the vertical plate 4. When demolding is required, the output end of the first hydraulic cylinder 6 is controlled to retract, driving the shell 7 to move upward, and the mold frame 3 can be driven to move upward through the abutment between the clamping groove 5 and the abutting portion 9, and when the clamping groove 5 abuts against the abutting portion 9, the second spring 14 is still in compression. When the housing 7 continues to move upward, the mold frame 3 can be driven to move upward by the contact between the card slot 5 and the abutting portion 9. When the mold frame 3 is completely separated from the brick blank, the cover plate 13 is still pressed on the upper part of the brick blank under the action of the second spring 14. At this time, the mold frame 3 can contact with the bending block 16 on the extension rod 15 to drive the cover plate 13 to move upward, so that the cover plate 13 can be separated from the brick blank. Place it on the workbench 1 and directly take the brick blank from the workbench 1. When the brick blank is taken out, the clamping groove 5 and the abutting part 9 are still in the abutting state, and the output end of the first hydraulic cylinder 6 is controlled to continue to retract. When the protrusion 12 enters the through groove, the clamping plate 8 is squeezed and enters the shell 7, and the clamping groove 5 is out of contact with the abutting part 9. Under the action of gravity, the mold frame 3 falls onto the workbench 1. At this time, the first hydraulic cylinder 6 stops working, and the brick blank raw material can continue to be added to the mold frame 3.

[0021] Furthermore, fixed columns 17 are respectively provided on the upper surface of the workbench 1 and the side of the mold frame 3. The two fixed columns 17 are connected by a tension spring 18. When the mold frame 3 moves upward, the tension spring 18 is in a stretched state. When the slot 5 is out of contact with the abutting portion 9, the mold frame 3 can be quickly restored to its initial position under the tension of the tension spring 18 and the gravity of the mold frame 3 itself. At the same time, the stability of the mold frame 3 can be improved to prevent it from moving up and down after being vibrated.

[0022] Furthermore, a docking groove 19 is provided on the upper surface of the workbench 1 , and the lower end of the mold frame 3 is located inside the docking groove 19 . The docking groove 19 can further improve the placement stability of the mold frame 3 .

[0023] Furthermore, an extension plate 20 is provided on one side of the workbench 1, and a second hydraulic cylinder 21 is provided on the extension plate 20. A push plate 22 is provided at the end of the second hydraulic cylinder 21. When the mold frame 3 and the cover plate 13 are separated from the brick blank, the output end of the second hydraulic cylinder 21 can be controlled to extend, and the brick blank formed on the workbench 1 can be pushed out through the push plate 22, thereby improving the efficiency of pushing out the brick blank.

[0024] Furthermore, a material guide plate 23 is provided on one side of the workbench 1, through which the bricks can be slid and transported to the conveyor belt, thereby reducing the moving distance of the workers in carrying the bricks and further reducing the labor intensity.

[0025] Working principle: When in use, a certain amount of brick raw materials is added into the mold frame 3, and then the cover plate 13 is driven to move downward by the first hydraulic cylinder 6, and the second spring 14 is continuously compressed, so that the cover plate 13 can squeeze the brick raw materials in the mold frame 3 to form. When the second spring 14 is compressed to a certain extent and maintained for a certain period of time, the mold frame 3 can be driven to move upward by cooperating with the clamping portion 9 on the clamping plate 8 and the clamping groove 5 on the vertical plate 4. Since the second spring 14 is still in a compressed state, the brick can be pressed by the cover plate 13 to prevent the brick from moving upward with the mold frame 3. When the mold frame 3 is completely separated from the brick, the mold frame 3 abuts against the bending block 16 on the extension rod 15, driving the cover plate 13 to move upward, so that the brick is separated from the cover plate 13, and then the brick can be removed from the workbench 1.

[0026] The device can control the mold frame 3 and the cover plate 13 to move in sequence, thereby controlling the mold frame 3 and the cover plate 13 to be able to successively break away from the brick blanks, and can safely and stably separate the brick blanks from the mold frame 3, thereby reducing the physical exertion of workers, which is beneficial to ensuring the efficiency of continuous production and having a good use effect.
