[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] like Figures 1 to 3 As shown, a synchronous lifting mechanism for a pressing head and demoulding of the utility model comprises a brick making frame 1, a first oil cylinder 2, a pressing frame 3, a pressing head 4 and a first gear set 5; the first oil cylinder 2 is arranged on the brick making frame 1; the pressing frame 3 is connected to the first oil cylinder 2 and is driven to rise and fall by the first oil cylinder 2; the pressing head 4 is arranged on the pressing frame 3; the first gear set 5 is provided with two groups, namely a first left gear set 5a and a first right gear set 5b, each group of the first gear set 5 comprises a first mounting seat 51, a first roller 52, a first gear seat 53, a first gear 54 and a first rack 55 The first mounting seat 51 is fixed on the brick making frame 1, the first roller 52 is rotatably set on the first mounting seat 51, the first tooth seat 53 is fixed on the brick making frame 1, the first gear 54 is rotatably set on the first tooth seat 53, the end of the first rack 55 is rotatably set on the pressing frame 3, one side of the first rack 55 is meshed with the first gear 54, and the other side of the first rack 55 is against the first roller 52; the first gear 54 of the first left gear group 5a and the first gear 54 of the first right gear group 5b are connected together through a first connecting shaft.

[0021] In this way, the utility model relates to a synchronous lifting mechanism for a pressure head and demoulding. When in use, the first oil cylinder 2 drives the pressure frame 3 to rise and fall, and the lifting of the pressure frame 3 drives the pressure head 4 to rise and fall, so that the pressure head 4 is close to or away from the mold frame. When the pressure head 4 is close to the mold frame, the pressure head 4 compacts the material in the mold frame. During the lifting process of the pressure frame 3, the lifting of the pressure frame 3 drives the first rack 55 to rise and fall. When the first rack 55 is lifted and lifted, it drives the first gear 54 to rotate. Since the first gear 54 of the first left gear group 5a and the first gear 54 of the first right gear group 5b are connected together through the first connecting shaft, when the pressure head 4 is lifted and lifted, the two first gears 54 rotate synchronously, and the phenomenon of inconsistent left and right heights is not likely to occur, and the lifting and lowering of the pressure head 4 is stable. Since the first gear group 5 is located as a whole on the upper part of the brick making frame 1, and the matching structure of the gear and the rack is adopted, the overall volume of the first gear group 5 is small, and the overall assembly process is more convenient.

[0022] Optionally, a guide column 11 is provided on the brick making frame 1, and a guide sleeve 31 capable of lifting and lowering along the guide column 11 is provided on the pressing frame 3. By providing the guide column 11 and the guide sleeve 31, the pressing frame 3 can be lifted and lowered along the guide column 11 more smoothly.

[0023] In this embodiment, the first mounting seat 51 includes a bottom plate 511, a first vertical plate 512 and a second vertical plate 513. The bottom plate 511 is fixed on the brick-making frame 1, the first vertical plate 512 is fixed on the bottom plate 511, a first groove is set on the first vertical plate 512, the second vertical plate 513 is fixed on the bottom plate 511, and a second groove is set on the second vertical plate 513; the first roller 52 includes a shaft body 521 and a roller body 522, one end of the shaft body 521 is located in the first groove, the other end of the shaft body 521 is located in the second groove, and the roller body 522 is rotatably set on the shaft body 521. In this way, when installing the first roller 52, the shaft body 521 is passed through the roller body 522, and then one end of the shaft body 521 is placed in the first groove, and the other end of the shaft body 521 is placed in the second groove, so that the shaft body 521 is installed on the first mounting seat 51, and the installation is more convenient.

[0024] Furthermore, it also includes a second oil cylinder 6, a lifting frame 7 and a second gear group 8. The second oil cylinder 6 is arranged on the brick-making frame 1. The lifting frame 7 can be lifted and lowered on the guide column 11. The lifting frame 7 is connected to the second oil cylinder 6 and is driven to lift and lower by the second oil cylinder 6. The second gear group 8 is provided with two groups, namely a second left gear group 8a and a second right gear group 8b. Each group of the second gear group 8 includes a second mounting seat 81, a second roller 82, a second tooth seat 83, a second gear 84 and a second rack 85. The second mounting seat 81 is fixed on the lifting frame 7, the second roller 82 is rotatably arranged on the second mounting seat 81, the second tooth seat 83 is fixed on the lifting frame 7, the second gear 84 is rotatably arranged on the second gear seat 83, and the end of the second rack 85 is rotatably arranged on the brick-making frame 1, one side of the second rack 85 is meshed with the second gear 84, and the other side of the second rack 85 is against the second roller 82; the second gear 84 of the second left gear group 8a and the second gear 84 of the second right gear group 8b are connected together by a second connecting shaft.

[0025] When in use, the second oil cylinder 6 drives the lifting frame 7 to rise and fall, and the lifting frame 7 drives the second gear 84 to rotate along the second rack 85. Since the second gear 84 of the second left gear group 8a and the second gear 84 of the second right gear group 8b are connected together by the second connecting shaft, when the pressure head 4 is lifted and lowered, the two second gears 84 rotate synchronously, and the left and right height inconsistency is not easy to occur, and the lifting and lowering of the pressure head 4 is stable. Since the second gear group 8 is located as a whole on the upper part of the brick making frame 1, and the matching structure of the gear and the rack is adopted, the overall volume of the second gear group 8 is small, and the overall assembly process is more convenient. The second gear group 8 is set on the basis of the first gear group 5, which further improves the stability of the pressure head 4 when it is lifted and lowered, so that the pressure head 4 is not easy to have the left and right height inconsistency phenomenon, and the demoulding effect is better.

[0026] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
