The mold is a core component of the brick-making machine that directly determines the size, appearance, and strength of the bricks. Maintenance must follow a standardized process: "Cleaning → Inspection → Repair/Replacement → Lubrication → Recording." Clear operating standards must be established for each step to prevent mold deformation and wear due to improper maintenance, which can compromise brick quality. The following are specific steps, standards, and precautions for mold maintenance:
1. Preliminary Preparation: Safety and Tool Verification
Before beginning maintenance, ensure operational safety and have specialized tools ready to prevent accidents or damage to the mold due to improper use of tools:

Safety Verification
Turn off the main power and hydraulic system switches of the brick-making machine, and display a "Equipment Maintenance in Progress, Do Not Start" warning sign to prevent accidental operation.
If the mold has just been removed from use, allow it to cool to room temperature (to avoid burns from a high-temperature mold, typically cool for at least 30 minutes, depending on the ambient temperature). Tool Preparation
Cleaning Tools: Soft wire brush (diameter ≤ 0.3mm, to avoid scratching the mold surface), nylon scraper, high-pressure air gun (pressure ≤ 0.6MPa), warm water (30-40°C, non-corrosive), neutral detergent (such as dishwashing liquid; strong acids/alkalis are prohibited).
Inspection Tools: Vernier caliper (accuracy 0.02mm), depth gauge, square, flashlight (for checking mold edges and gaps).
Repair/Lubrication Tools: Specialized mold repair welding rods (matched to the mold material, such as J422 welding rods for 45# steel), angle grinder (with flap disc for grinding), high-temperature grease (type must comply with the equipment manual, such as lithium-based grease No. 2), grease gun. II. Core Step 1: Mold Cleaning (Must be performed during every shutdown/mold change to prevent material agglomeration and wear).
The key to cleaning is to "thoroughly remove residual material without damaging the mold surface." This process is divided into three steps:

Initial Cleaning (Removing Large Residues)

Use a nylon scraper to gently scrape away any unagglomerated material along the mold's inner walls (cavity, side molds, and guide pin holes). Avoid excessive force, which may cause the scraper to scratch the mold surface (especially the smooth surface of the cavity).

If there are large lumps of material (such as hardened cement), do not strike with hard objects such as hammers or chisels. First, soak the mold cavity in warm water for 10-15 minutes to soften the lumps, then gently brush them away with a soft wire brush.

Deep Cleaning (Removing Residue in Crevices)

Use a high-pressure air gun (set to medium-low pressure) to remove fine dust from hidden areas such as mold corners, guide pin gaps, and locating pin holes. (Keep the air gun nozzle at least 10 cm away from the mold surface to prevent high-pressure airflow from damaging the mold.) If the mold cavity is greasy (such as from previous lubrication residue), wipe it with a cloth dampened with neutral detergent and then dry it with a dry cloth to prevent detergent residue from sticking to the raw materials.

Cleaning Standards
The mold interior, cavity, and guide pin/locating pin surfaces must be free of visible raw material residue, oil, or dust.

Touch the mold cavity surface; it should not feel rough or grainy.

The guide pin and locating pin holes must be unobstructed and free of obstruction (test by inserting a guide pin/locating pin of the appropriate specification; they must fit smoothly and without any sticking).

material adaptability, using waste materials such as construction waste and fly ash. This not only addresses raw material shortages but also cuts costs and is environmentally friendly, unlike machines limited to traditional materials. Secondly, they can produce a wide variety of bricks, including slope - protection bricks and hollow bricks, meeting diverse construction needs better than single - function machines. Operation and maintenance are easy due to high automation and possible modular design, reducing labor costs and downtime. With advanced technologies, they achieve high production efficiency and stable product quality, detected by optional visual systems. Finally, they have energy - saving and environmental protection advantages, with low energy consumption and zero - pollution production, making them highly competitive in a strict - regulation market.

 Classification and Screening The collected waste materials are first classified. Different types of waste have distinct characteristics and compositions. Classification facilitates subsequent processing and proportioning. Oversized impurities and foreign objects are screened out to ensure the relatively stable quality of the waste materials entering the brick - making process. #### Crushing and Grinding Larger waste materials, such as concrete blocks in construction waste and tailings, are crushed by crushers to reduce their particle size. Some waste materials, like fly ash and stone powder, also need to be ground. This increases their specific surface area, enhancing the mixing uniformity with other raw materials and the reaction activity.

Nianpeng brick - making machines take several effective measures in energy - saving and environmental protection. In terms of raw material utilization, they can make full use of waste materials such as construction waste, fly ash, and tailings. This not only reduces the exploitation of natural resources but also addresses the problem of waste disposal, cutting down on environmental pollution. It's estimated that by using these waste materials, it can save up to 60% of natural raw materials. Regarding energy use, they are equipped with high - efficiency motors and hydraulic systems. The energy - saving hydraulic pumps can adjust power output according to the workload, potentially reducing energy consumption by about 30%. In the heating and drying processes, advanced technologies like electromagnetic heating are likely adopted, with waste - heat recovery systems in place to reuse the heat, which may improve energy utilization by 20%. Moreover, the intelligent control system monitors the operation status and energy consumption in real - time, making automatic adjustments for precise control. The machines also employ clean production processes, achieving zero - emission of pollutants, which significantly benefits the environment.
