Block Forming Machine Mold

Precision manufacturing is meticulous. A single brick pattern drawing (standard brick, perforated brick, permeable brick, etc.) is used for professional design and processing. CAD/CAM software is employed for mold design, with key optimizations including draft angle (typically 0.5°-1°), scientific placement of vents, and thickened structural design for easily worn areas. 3D modeling simulates the brick forming process, pre-identifying and mitigating defects such as cracking, missing corners, and air bubbles. Laser cutting or plasma cutting ensures smooth edges with a tolerance of ≤±0.5mm. High-precision machining is performed using CNC machining centers and wire EDM technology, controlling core dimensions to a tolerance of ±0.02mm and flatness ≤0.01mm. Heating to 200℃-400℃ effectively eliminates quenching stress and improves mold crack resistance.

In terms of mold materials and strengthening processes, QT460 alloy steel plate is selected as the base material, refined using a carburizing and quenching process, possessing excellent properties such as high strength, deformation resistance, and ultra-wear resistance. During the quenching process, the mold steel is precisely heated to 950℃-1050℃, followed by oil/air cooling after heat preservation, causing the steel to form a martensitic structure and increasing its hardness to HRC58-62. A tempering process is also included. Surface strengthening carburizing/nitriding increases the surface hardness of the mold to over HV1000, extending the life of the core rod. For the specific needs of permeable brick molds, a customized TD treatment/titanium plating process is used to form a dense, wear-resistant protective layer on the mold surface, achieving the dual effects of anti-sticking and easy demolding, adapting to the special working conditions of permeable brick molding.

The assembly of the mold core, mold frame, pressure head, and demolding mechanism employs a double-fastening scheme of locating pins and bolts to ensure the coaxiality accuracy of each component. This ensures a smooth and seamless demolding process without any jamming or stuttering, preventing common mechanical issues in high-frequency production cycles.

We can customize molds of different specifications and shapes (such as irregularly shaped bricks, paving bricks, and grass pavers) according to customers' individual needs. This helps partner companies mass-produce high-value-added brick products, efficiently expand their market share, and continuously improve their core profitability through superior product differentiation.
