Processing requirements of LED mold parts:

Long service life of LED mold parts. From the use point of view, the higher the life of LED mold parts, the better. This is a comprehensive index for die designers and manufacturers, which not only promotes the application of new die materials, but also brings new requirements for die production, such as high machining accuracy and low surface roughness.

Short production cycle. Due to the acceleration of new product upgrading and the increasingly fierce market competition, users require the production cycle of die parts is becoming shorter and shorter. The production management, design and process of LED mold parts should be adapted to this requirement. Improve the mold modern design, manufacturing and standardization level, in order to shorten the manufacturing cycle.

Low cost. The processing cost of LED mold parts is related to the complexity of mold structure, mold materials, manufacturing accuracy and other requirements and processing methods. Must according to the product requirements reasonable design and customization of its processing technology, reduce the cost.

Complete set production. When a piece needs more than one pair of mold processing, the product made by the former mold is the blank of the later mold, the mutual association between the molds is restricted, only the final product is qualified, this series of molds is qualified. Therefore, this feature must be fully considered in the production and planning of LED mold parts.

Required to test the mold and repair. The design and production of LED mold parts are related to experience in addition to their own characteristics. Some parts of the mold parts need to be determined by trial repair. After assembly, the mold parts must pass test punching or pressure test to determine whether the mold parts are qualified. Therefore, in the production schedule must leave a certain trial cycle.

Basic characteristics of mold processing:

(1) Machining accuracy requirements of high pay die is generally composed of concave die, punch die and die frame, some may also be multi-piece integrated module. Therefore, the combination of upper and lower die, the combination of insert and cavity, and the combination between modules require high machining precision. The dimensional accuracy of precision die is usually up to u m class.

(2) Complex shape surface Some products such as automobile covering parts, aircraft parts, toys, household appliances, the shape of the surface is made of more seedlings classic surface group warehouse, therefore, the mold cavity surface is very complex. Some surfaces have to be treated with numerical sense

(3) Batch small die production is not mass production, in many cases, often only one payment.

(4) In the process of multi-die processing, milling, boring, drilling, comparing and tapping are always used.

(5) The use of repetitive production linton mold has a life. When the use of a die exceeds its life, it is necessary to replace a new die, so the production of the die is often repetitive.

(6) Copying processing Sometimes there is no drawing or data in mold production, and the copying processing should be carried out according to the real object. This requires high precision imitation, no deformation.

(7) Excellent mold materials, high hardness, the main materials of the mold are made of high quality alloy steel, especially the mold with high life, often made of Cr12, CrWMn and other Leytenite steel. This kind of steel from blank forging, processing and heat treatment have strict requirements. Therefore, the preparation of processing technology can not be ignored. Heat treatment deformation is also a serious problem in processing.
