Mold manufacturer , the design is more high-end products, is an effective means to enhance the competitiveness of enterprises . The development trend of intelligent social life , is prompting mold manufacturing from traditional areas into production among intelligent , then the future development of China's mold in turn show how intelligent trend?

      Well , according to David ball joint is understood that two open mold manufacturing rubber seals . Two open seals die after monomer components used in the manufacturing process , and then match the assembly , processing quality, mold testing convenient. Single cavity mold material selection CrlZ, linking 45 steel plates . Mold processing, in addition to the drawings in strict accordance with mold processing, and ensure the cavity size , the following points are key to ensuring the mold machining accuracy :

    (l) plastic tank stream processing : processing quality seal mold flow past plastic tank does not get enough attention , stream processing plastic tank too often or too far away from the cavity size is difficult to control , pruning difficult to make products , product unsightly . Two open seal mold has been improved to address these issues , triangular plastic flow tank size and product end outer diameter size consistent ( zero zero ) , the use of the outside of the lower die here like forming a sharp edge when seal molding, cutting down excess flash i.e. , not only simplifies the trimming process , but also improves the appearance of the product quality. As the flow of plastic tank and the outer diameter of the cavity are in different modules, the size of the interference does not occur, it is also easy to ensure accuracy .

    ( 2 ) the mold and the mold core with processing 1 : The upper mold and the mold core with a tie for the taper , spotting method previously used , requiring the contact rate of 80 %. This traditional way of processing is not only difficult, but also spent a lot of hours , is still difficult to achieve the desired effect no burrs . The new structure mold processing using cone angle of inclination angle of inclination of the cone axis than smaller ways to make the mold and the mold core at the parting line b always fit tightly together in a gapless fit state, the product does not exist in the flash here . And mold manufacturing process improvement .

    ( 3 ) on a mandrel and the mandrel on the nip of 2: 1 and the upper mold core laminated on the core 2 is the key size and the auxiliary sealing lip seal to ensure the accuracy . Flash three open Vice lip seal mold Department, deputy lip appearance quality at a great impact . The new structure of the upper mold and the upper mold core a interference fit of the core 2 , the monomer processed by hot pressing integrally inflation method , and then the fastening screws on the upper end of the mandrel 2 pulled tightly effectively Vice lip to prevent loosening of the two cores .

    ( 4 ) is connected between the mold cavity : each associated with a single cavity mold plate is connected must have a certain amount of floating , in order to ensure flexibility in opening and closing the mold , and accurate alignment . General singlemode gap between the plates and the associated control 0.50 a 1. 0rnm. The gap is too large could easily lead to the partial use of a rotating shaft seals die when the new structure is too oblique to develop mold , mold wear increased , affecting the life of mold ; gap is too small, so that interference occurs between the mold cavity operation when the card too dead .

      Well , according to David ball joint note , rotary shaft seal developed two open mold to change the traditional structure of the three types of mold , so that the appearance and performance of seal products is guaranteed , greatly improved work efficiency . The successful development of the new structure of the mold for domestic enterprises to promote the significance of the oil seal .
