Description

TECHNICAL FIELD

[0001] The present application relates to the field of concrete brick preparation, in particular to a concrete brick block pressing forming equipment. BACKGROUND

[0002] The pressing forming process of concrete bricks is a core link in industrial production. The process rapidly presses the concrete mixture into the mold cavity through high pressure (usually 10-30 MPa), and realizes densification with vibration. However, if the gas (including air carried by mixing water, air gap between aggregates, and micro-bubbles generated by chemical reaction) in the mixture cannot be effectively discharged during pressing, it will cause the formation of pores inside the brick and the appearance of honeycomb defects on the surface, thereby reducing the mechanical strength, durability and appearance quality of the product.

[0003] The traditional process relies on mechanical extrusion and vibration during pressing to allow the gas to naturally escape from the mold gap. However, the high viscosity of the concrete mixture (especially for low water-cement ratio formulations) results in high resistance to gas migration, leading to low exhaust efficiency. Experiments show that when relying solely on natural exhaust, the porosity of the brick is as high as 4-8%, and the compressive strength is reduced by 15-30%. In particular, when the gas is discharged from the mortar, it will accumulate at the top, so it is particularly necessary to discharge from the top. However, mechanical pressing also needs to be done from top to bottom, which affects the arrangement of the exhaust structure and is very inconvenient. SUMMARY
