Prefabricated Housing Molds

Prefabricated housing molds are key industrial equipment that achieve concrete forming through specific structural forms, commonly using steel molds as the main structure. The following provides an introduction from aspects such as types, core functions, design considerations, and technological developments:

I. Diverse Types

1. Cement House Molds: Evolved from traditional large steel building formwork, these are used for factory-prefabricated integral concrete houses. Core components include mold liners, exterior wall molds, bases, and slide rails, with a self-weight exceeding 20 tons. After four generations of technological upgrades, the molds can be reused for about 5-8 years, with wall thicknesses of 14-17 cm and panel thicknesses of 10-13 cm, enabling centralized prefabrication of components to shorten construction periods.
2. New Modular Concrete Prefabricated House Molds: Heavy-duty equipment divided into exterior and interior lining molds, capable of casting concrete into pentahedral boxes, but with the issue of high mold costs.
3. Fezhm Fully Automatic 3D Prefabricated House Molds: Fully automatic hydraulic molds with mold opening and closing times not exceeding 3 minutes, capable of producing two rooms per day, significantly improving production efficiency.
4. Prefabricated Component Molds: Used for producing six types of standard components such as composite floor slabs and balcony slabs, with high reuse rates for large base-type molds. The typical structure consists of standardized components of base molds, side molds, and end molds, divided into independent molds (with a large amount of steel, suitable for single repetitive projects) and large base-type molds (with shared base molds and reusable side molds).

II. Core Functions

1. Wet Demolding Technology: Achieves non-destructive separation of uncured components through wing-shaped torsion spring positioning and oil lubrication in slide slots, improving movement efficiency.
2. Modular Design: The modular design of chamfer forming tooling reduces mold modification costs and improves production line adaptability.
3. New Positioning Systems: Such as magnetic box-fixed side molds, enhancing mold positioning accuracy and stability.

III. Design Considerations

1. Structural Performance: Molds must have sufficient bearing capacity, stiffness, and stability to withstand the weight of concrete, lateral pressure, and working loads.
2. Dimensional Accuracy: Design must consider concrete setting expansion allowances to ensure component dimensional accuracy, while facilitating steel bar installation, concrete pouring, and curing.
3. Demolding Convenience: Components must be firmly connected, embedded parts securely fixed, and reinforcement bar exit methods must balance notch sizes to avoid grout leakage or affect demolding.
4. Versatility and Turnover: Increase turnover times through reasonable stiffness design and improve reuse rates by adopting modular and combined structures.

IV. Technological Developments

1. Material Innovation: Exploring the composite application of fiberglass and aluminum alloy, reducing weight compared to traditional steel molds while maintaining the same stiffness.
2. Automation Upgrades: Focusing on the composite application of automated demolding devices and lightweight materials, improving turnover efficiency through design optimization.
3. Design Optimization: Promoting modular design, combined molds, and structural optimization to reduce modification costs and improve production line adaptability.
