The design of the cooling system is a relatively cumbersome work, namely to consider the uniformity of the cooling effect and cooling, but also consider the impact of the cooling system on the overall structure of the mold. Arrangement and the specific form of the cooling system cooling system; cooling system of determining the specific location and size; key parts such as the movable die or the cooling insert member; cooling side slider and the side core; the design of the cooling element and the cooling criteria selection of components; seal design. Plastic mold in every aspect of our lives, plastic mold design for use in different industries, targeted design of plastic mold, easy to operate and practical mold. Convenient and practical plastic mold design, mold design and good structure will be more user-friendly use of Shenzhen plastic mold, save time and improve efficiency. Sufficient wear resistance due to surface wear is one of the main failure mode of the mold, so the mold should have sufficient hardness to ensure wear resistance of the mold, to ensure the life of the mold. Usually need to select the appropriate materials and appropriate heat treatment methods to meet the requirements of hardness. But when the hardness reaches a certain value, the hardness of the wear resistance improving effect is not obvious. Reduce heat deformation effects due to injection-molded parts are often more complex shapes, plastic mold after the hardening process is difficult, and sometimes impossible process. In order to increase the hardness, must be subjected to heat treatment. To take appropriate measures to reduce the impact of heat deformation, must be processed for mold after heat treatment, heat treatment should be used in small material deformation.
