Packing Crate Mould

Introduction

Packaging box molds are special tools used to manufacture various packaging boxes. Their main function is to process raw materials into packaging boxes with specific shapes, sizes and functions through specific designs and processes.

Manufacturing process

1. Mold design
Use computer-aided design (CAD) software to carry out detailed mold design, combine the functional requirements of foldable plastic packaging boxes, optimize the flow channel, exhaust and cooling system of the mold, and ensure the fluidity of plastic materials and product quality during the injection molding process.

2. Mold material selection
Select high-quality mold steel, such as P20, 718, 2738, etc., to ensure that the mold maintains stability and wear resistance during long-term use, and use C45 steel as the mold frame material to improve the structural strength and deformation resistance of the mold.

3. Injection molding process
The hot runner injection system is used to ensure the uniform flow of plastic melt in the mold, reduce material waste during the injection molding process, and improve production efficiency. The mold is suitable for 470-ton injection molding machines to ensure sufficient injection pressure and injection speed.

4. Mold processing technology
Use high-precision CNC machine tools to process the cavity and core to ensure the accuracy of the mold size. After the mold processing is completed, the surface is polished, hardened, etc. to improve the durability and corrosion resistance of the mold.

5. Mold assembly and testing
Assemble all parts (such as cavity, core, hot runner system, etc.) and ensure the tightness of each part to avoid leakage or incomplete injection. Perform mold trials to check whether the product size, appearance, strength, etc. meet the requirements.

How to maintain

1. Regular cleaning
Clean the mold cavity and core regularly to prevent the accumulation of plastic residues, which may cause damage to the mold surface or uneven injection.

2. Check the cooling system
Check whether the cooling channel is unobstructed regularly, clean the cooling water pipe, ensure the coolant is flowing smoothly, avoid pipe blockage, and affect the cooling effect of the mold.

3. Maintain the hot runner system
The hot runner system should be cleaned regularly to avoid blockage of the hot runner nozzle and ensure good fluidity of the injection molding material.

4. Lubrication and rust prevention
Regularly add lubricating oil to the moving parts of the mold (such as sliders, push rods, etc.) to reduce friction and ensure smooth operation of the mold.

5. Storage
When the mold is not in use, store it in a dry, dust-free, non-corrosive gas environment to avoid moisture and chemicals from damaging the mold.
