Forming die for high-abrasion-proof composite sintered building blocks

The utility model discloses a high-wearable composite sintered brick molding die, and belongs to the extrusion mechanism of a brick/tile machinery, which comprises a machine port, a machine head and an oil distribution disc, wherein, the machine port is coupled with a machine-head even-joint flange through a fixed block; the machine head is coupled with the oil distribution disc through a bolt, so that the machine port, the machine head and the oil distribution disc are integrated into a whole body; a layer of high-wearable material is added to the inner wall of the machine port and/or the machine head as a machine-port lining plate and a machine-head lining plate. The molding die has low cost, simple compound process and firm and reliable connection of the compounded surfaces. After the wearable layer on the machine port/machine head is worn, the wearable layer can be re-compounded by adopting the explosion-stripping craftwork. The machine port and the machine head can be used repeatedly, thereby realizing t
