INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a mold core, and more particularly to a mold having a high hardness and easy release. [Prior Art] Molding is widely used in the molding process, especially in the manufacture of optical glass products, such as aspherical glass lenses, ball lenses, crucibles, etc. Direct optical molding can be directly produced by Direct Press-molding technology. There is no need for subsequent processing steps such as grinding and polishing, which can greatly improve the production rate and output' and the product quality is good. However, the direct compression molding method requires very high requirements for chemical stability, thermal shock resistance, mechanical strength, and surface smoothness of the mold. Therefore, the development of compression molding technology actually depends mainly on the improvement of mold core materials and mold manufacturing technology. Generally, the mold core has the following requirements: a. At high temperature, it has good rigidity and hardness sufficient for mechanical impact; b. The mold does not produce grain under the thermal shock of repeated and rapid heating and cooling. Deformation; Clothing c. In the high J Kun time mold surface molding and optical glass does not occur, do not adhere to the glass; long d. no high temperature oxidation; surface finish profile e: good processing performance, easy to process into high Accuracy and high table f. Low cost. Most of the traditional mold cores use non-recorded steel or heat-resistant alloy as the mold material.
