With the function of hiding screen of green laser pointer

 With the function of hiding screen of green laser pointer , teachers can successfully transfer one teaching task to another.
There are many rubber and plastic products in our daily lives, these products are mostly made through a variety of mold these molds are often contaminated in the production process and corrosion, and thus the impact on production, so the mold cleaning, thus ensuring the quality of rubber and plastic products. After a long period of exploration and practice, has accumulated a lot of cleaning mold. Initially use high-temperature alkaline soak method mold cleaning, followed by the method of blasting, chemical cleaning method, dry ice and high pressure water cleaning method, but not fundamentally achieve the purpose of cleaning the mold and can not meet the community needs. Therefore, the sights on a new cleaning technology - the laser cleaning of mold technology. green laser pointer will enhance learning outcome.
Laser cleaning technology refers to the use of high-energy laser beam on the workpiece surface, the surface of the particles, rust, and coating the instant evaporation and stripping, so as to achieve a clean process. Laser cleaning mold laser energy irradiated to the mold surface, which can cause mold surface temperature, this temperature change can effectively remove the mold surface contaminants and mold surface damage plays a vital role view of the mold surface temperature changes is the premise of the laser cleaning mold mechanism. With the maturity and perfection of the development of computer technology, as well as large general-purpose finite element software in the processing of thermal properties, radiation, convection heat transfer, and other factors. With green laser pointer , teachers can effectively control the computer all around the classroom.
The numerical simulation technique used for the calculation of the laser cleaning the mold surface temperature field has increasingly shown its superiority, the article is based on using ANSYS finite element software, finite element model of the laser cleaning mold surface transient temperature field. Finite element model is established.
