Images of House Prefabricated Component Moulds

Currently, it is not possible to directly provide images of house prefabricated component moulds, but a popular science explanation of their types, structural characteristics, and design points can be provided.

House prefabricated component moulds are specialized tools used for producing concrete prefabricated components. Their design directly affects the dimensional accuracy, surface quality, and production efficiency of the components. Depending on the type of component, moulds can be classified into the following categories:

1. Common Types of Prefabricated Component Moulds

• Wall Panel Moulds: Used for producing building exterior and interior wall panels, these moulds typically feature a steel frame structure with adjustable locating pins and draft angles inside to ensure that components are not easily damaged during demoulding. The side panels of the moulds may be equipped with magnetic fixing devices for quick assembly and disassembly.
• Floor Panel Moulds: Designed for floor panels and composite panels, these moulds have a flat steel plate at the bottom and side moulds around the perimeter to control the thickness of the components. Some moulds adopt a hinged structure for easy and quick demoulding after concrete pouring.
• Beam and Column Moulds: Used for producing structural components such as beams and columns, these moulds need to withstand significant lateral pressure from the concrete. Therefore, they are often made of thickened steel plates welded together, with reinforcing ribs inside to increase rigidity. The ends of the moulds may be designed to be detachable to accommodate the production needs of components of different lengths.
• Special-Shaped Component Moulds: For components such as balcony panels and stairs, moulds need to be customized according to the shape of the components. These moulds typically adopt a segmented design, with each part connected by bolts to ensure the overall stability of the mould.

2. Core Points of Mould Design

• Material Selection: The main body of the mould is mostly made of Q235 or Q345 steel, and the surface needs to undergo anti-rust treatment (such as sandblasting and painting) to extend its service life.
• Demoulding Design: The inner walls of the mould need to be provided with a draft angle of 1°-3° to reduce the friction between the component and the mould; at the same time, areas for applying demoulding agents should be set at key parts (such as corners and reserved holes) to reduce the risk of sticking.
• Accuracy Control: During mould processing, dimensional tolerances need to be strictly controlled (usually ≤ ±1mm), and processes such as laser cutting and CNC bending should be used to ensure the assembly accuracy of various components.
• Positioning of Reserved Holes and Embedded Parts: The mould needs to be designed with special positioning devices (such as locating pins and magnetic fixing blocks) to ensure that the positional accuracy of embedded bolts, wire boxes, and other components meets the design requirements.

3. Mould Use and Maintenance

• Before use, check the flatness and cleanliness of the mould surface to avoid concrete sticking or surface defects.
• After demoulding, promptly clean the residual concrete inside the mould and apply a demoulding agent for the next use.
• When not in use for a long time, the mould should be stored in a dry and ventilated place to avoid rusting or deformation.
