       The key design points of toolbox molds revolve around product accuracy, production efficiency, and molding quality, with five core dimensions.
1. Design of cavity and structure
       Correctly match the size, wall thickness, and appearance contour of the toolbox, and reserve reasonable shrinkage allowance.
       Optimize corner and edge design, use circular arc transition to avoid stress concentration and product cracking.
2. Demoulding mechanism design
       Choose the appropriate demolding method based on the structure of the toolbox, such as ejector pin, top plate, or inclined top mechanism.
       Ensure even distribution of demolding force to avoid product deformation or surface scratches.
3. Cooling/Heating System Design
       The cooling pipes are evenly arranged to ensure consistent temperature in the mold cavity and shorten the molding cycle.
       Strengthen cooling for complex structural areas to prevent defects such as shrinkage marks and bubbles.
4. Feed and exhaust system design
       The gate position should avoid the critical appearance surface of the product to ensure smooth filling of the melt.
       Reasonably set up exhaust slots to discharge the gas inside the mold cavity and avoid burning and material shortage problems.
5. Strength and durability design
       The mold cavity is made of high-strength wear-resistant materials to extend its service life.
       Optimize the mold guiding mechanism to ensure the accuracy and stability of mold opening and closing.
