Detailed Description

the invention will be further described with reference to the accompanying drawings and embodiments.

As shown in fig. 1, the pressure head supporting and limiting structure for a block making machine provided by the present embodiment comprises a frame 10 and a pressure head mounting plate 20 of the block making machine, and the structure and the connection position relationship of the frame 10 and the pressure head mounting plate 20 are the same as those of a conventional block making machine, and are not the focus of the present embodiment, and are not described in detail herein. In addition, the pressure head supporting and limiting structure for the block making machine provided by the embodiment further comprises a cylinder 30 and an upper connecting rod 40 and a lower connecting rod 50 which are rotatably connected with each other at one end.

one end of the upper connecting rod 40, which is not connected with the lower connecting rod 50, is rotatably connected to a position of the rack 10 right above the pressure head mounting plate 20, one end of the lower connecting rod 50, which is not connected with the upper connecting rod 40, is rotatably connected to the pressure head mounting plate 20, and the connecting position between the upper connecting rod 40 and the rack 10 and the connecting position between the lower connecting rod 50 and the pressure head mounting plate 20 are located on the same vertical line, so that after the upper connecting rod 40 and the lower connecting rod 50 are mutually unfolded, the upper connecting rod 40 and the lower connecting rod 50 are located on the same vertical line, the demolding force borne by the pressure head mounting plate 20 can be transmitted to the rack 10, meanwhile, the downward sliding stroke of the pressure head mounting plate 20 can be limited, and further the lower limit position of the.
