Auto Light guide mould

Patterned tooth insert structure for light guide mold

A pattern tooth insert structure for a light guide mold, comprising: a movable mold insert, characterized in that a tooth insert is arranged beside the movable mold insert, and the pattern tooth insert can be set and fixed in the movable mold insert a block tooth is formed on one side of the movable mold insert, and an end surface for forming the light guide strip is formed with a pattern tooth, and the pattern tooth insert is provided with a cover insert for forming a light guide. The arc side of the product. According to the utility model, the root of the tooth of the individual tooth insert can be processed into position, and the processing precision of the reflecting surface is effectively improved. In addition, the tooth insert is small in volume, easy to replace, and the replacement cost is low.

Design and manufacturing technology of the light guide mold

Master the design and manufacturing technology of the long cylindrical light guide mold, master the control method of controlling the shrinkage, warpage, bubble and filling dissatisfaction of the super long cylindrical product, master the multi-point seamless injection process in the strip light guide The application, as well as the precision control of the high-precision incident surface and the high-precision machining of the tooth profile. Accumulate experience, broaden the company's mold production field, ensure the company's absolute advantage in the market competition, promote the development of the domestic mold industry, and meet the automotive industry's demand for high-end molds.

Creativity and advancement machining process on the light guide mold

1. The micro-optical pattern insert inlay technology is adopted, and the pattern insert is integrated to enhance the rigidity of the insert, avoid the cumulative error of the multi-part inlay, and ensure the design life of the insert;
2. The milling micro-tool cutting method is R0 The application of .05mm micro-milling cutter in the milling machining center solves the problem that the small tool is easy to wear and break easily;
3. It is easy to solve the thick-walled light-conducting plastic parts by using the low-speed, high-pressure injection process and the injection speed segmentation control injection molding process. The problem of causing sink marks;

Social and economic benefits from the light guide mold

1) Conducive to improving the comprehensive ability of domestic mold technology The core design and processing technology level of this project has reached the highest level of such international products, and the milled miniatures independently developed by the company. The cutting method of the tool, that is, the application method of the R0.05mm micro-milling cutter in the milling machining center, realizes the processing of the ultra-high surface quality requirements of the optical pattern and the processing of the minimum machining fillet of less than or equal to R0.05mm.
