1. Product design and requirement analysis
Before developing a mold for a wooden toilet lid, it is necessary to clarify the design intent and functional requirements of the product, including size, shape, surface quality, assembly requirements, etc. For example, when designing, it is necessary to consider the integrity of the product’s appearance, the setting of the parting surface, and the detailed features after injection molding.

2. Mold design
Structural design: Based on product requirements, design the parting surface, cavity, and core structure of the mold to ensure its accuracy and stability.
Pouring system design: Reasonably design the pouring system, including the shape, position, and size of the sprue, to reduce molding defects.
Cooling system design: Optimize the layout of the cooling water circuit to ensure rapid and uniform cooling of the product, reducing cooling deformation.

3. Material selectionChoose suitable mold materials, such as high-strength mold steel (such as P20, H13, etc.), to ensure the hardness, wear resistance, and toughness of the mold.
4. Mold manufacturing
Precision machining: Using CNC machining centers to process mold parts, ensuring dimensional accuracy and surface roughness of parts such as cavities and cores.
Heat treatment: Preheating, quenching, tempering and other processes are carried out on mold parts to improve the hardness and service life of the mold.
