The heat treatment equipment technology and mold quality are very close, making these two technologies mutually promote and improve together in the process of modernization. In recent years, the rapid development of international mold heat treatment technology is vacuum heat treatment technology, mold surface strengthening technology and mold material pre-hardening technology.
Vacuum heat treatment technology is a new type of heat treatment technology developed in recent years. It has the characteristics that are urgently needed in mold manufacturing, such as preventing oxidation and non-decarburization, vacuum degassing or degassing, and eliminating Hydrogen embrittlement improves the plasticity, toughness and fatigue strength of the material. The slow vacuum heating and the small temperature difference between the inside and outside of the parts determine the small deformation of the parts caused by the vacuum heat treatment process.

According to the different cooling media used, vacuum quenching can be divided into vacuum oil quenching, vacuum quenching, vacuum water cooling and vacuum nitrate austempering. The main applications in the mold are vacuum oil quenching, vacuum air quenching and vacuum tempering. In order to maintain the excellent characteristics of vacuum heating of the workpiece, the selection and formulation of coolant and cooling process are very important. The quenching process of the mold mainly adopts oil cooling and air cooling.

For mold working surfaces that are no longer mechanically processed after heat treatment equipment, vacuum tempering should be used as much as possible after quenching, especially vacuum quenched workpieces, which can improve the mechanical properties related to surface quality. Such as fatigue performance, surface brightness, corrosion, etc. The intelligence of the mold includes: clarifying the mold structure, materials, and performance requirements: computer simulation of temperature field and stress field distribution during mold heating; computer simulation of temperature field, phase change process and stress field distribution during mold cooling; heating and cooling process Process simulation; formulation of quenching process; automatic control technology of equipment.

In order to meet the quality requirements of heat treatment equipment parts to the greatest extent and reduce the distortion and quality dispersion of parts as much as possible, various precision technologies should also be actively promoted. At present, we must first take effective measures as much as possible to actively promote various types of heating technologies with little oxidation and various cooling technologies that reduce component distortion. Efforts should be made to integrate and infiltrate information technology, sensor technology, computer technology, and other high-tech with heat treatment technology, so that the traditional technology can get a qualitative leap on the existing basis, so as to ensure that the quality of parts is greatly improved.
At the same time, the heat treatment equipment industry associations and societies must create conditions to strengthen the exchanges and cooperation between domestic and foreign enterprises with conditions, so that Chinese enterprises can accelerate the pace of going abroad, and more quickly integrate with international advanced technology standards and management methods. Adapt to the increasingly fierce market competition at home and abroad.

On the basis of actively promoting many effective advanced technologies at home and abroad, we must combine the characteristics and needs of domestic production, innovate and reserve, so as not to be controlled by others, and to ensure that we can stand in the fierce market competition. invincible position. Improve the quality of the industry's workforce as soon as possible. The society must actively create conditions, adopt various forms in accordance with different requirements, and focus on training key employees and technicians in key positions, technical and management backbones, and business leaders, learn basic requirements for positions, and enrich relevant high-tech, advanced technology and management knowledge. Lay a good foundation for gradually improving the quality of the industry's workforce.
