        開模具需要對模具鋼做個基本的判斷

        開模具如何選定合適的模具鋼呢?其實選模具鋼主要的影響因素是產量,客戶期望,價格。低價格模具,很多采用45#鋼調質使用。所以,低端模具基本上就忽略了其它的因素。排除低端模具外,按正常的思路,從模具的角度來說,模具鋼的選用應考慮塑料是否具有腐蝕性,產品是否有鏡面拋光,蝕紋要求,模具零件的磨損性能等。在這基礎之上,再考慮模具量產等級。
        How to select the appropriate die steel for die opening? In fact, the main factors affecting the selection of die steel are output, customer expectations and price. Low price moulds, many of which are made of 45\\. Therefore, the low-end mold basically ignores other factors. Excluding low-end molds, according to the normal idea, from the perspective of molds, the selection of mold steel should consider whether the plastic is corrosive, whether the product has mirror polishing, etching requirements, and the wear performance of mold parts. On this basis, consider the mold mass production grade.
        此外高碳模具鋼強度大,硬度大,用于切削刀具,工具鋼。低碳模具鋼:拉伸時的應力-應變曲線主要分四個階段:彈性階段、屈服階段、強化階段、局部變形階段,在局部變形階段有明顯的屈服和頸縮現象。開始時為彈性階段,完全遵守胡克定律沿直線上升,比例極限以后變形加快,但無明顯屈服階段。低碳模具鋼塑性強,硬度高,抗拉強度好,多用于結構承載上。
        In addition, high carbon die steel has high strength and hardness. It is used for cutting tools and tool steel. Low carbon die steel: the stress-strain curve during stretching is mainly divided into four stages: elastic stage, yield stage, strengthening stage and local deformation stage. There are obvious yield and necking phenomena in the local deformation stage. At the beginning, it is the elastic stage, which fully obeys Hooke's law and rises along a straight line. After the proportional limit, the deformation accelerates, but there is no obvious yield stage. Low carbon die steel has strong plasticity, high hardness and good tensile strength. It is mostly used for structural bearing.
        開始報模具價格時,很多客戶是指定模具鋼,除特別不合理之外,一般都是順應客戶的意愿。若客戶沒指定,則應先跟客戶溝通,確定好使用模具鋼之后,再報模具價格。而這里,就需要對模具鋼做個基本的判斷,大致總結歸納如下:
        At the beginning of quoting mold prices, many customers specify mold steel. Except for being unreasonable, they generally comply with the wishes of customers. If the customer does not specify, it should first communicate with the customer to determine the use of die steel, and then quote the die price. Here, we need to make a basic judgment on the die steel, which is roughly summarized as follows:
        低端低價模,用45#模具鋼或P20模具鋼。
        Low end low-cost die, 45\\p20 die steel or die steel.

        高價模,高鏡面要求用S136模具鋼,腐蝕性強用1.2316模具鋼
        S136 die steel is required for high price die and high mirror surface, and 1.2316 die steel is required for strong corrosion
        沒腐蝕性用NAK80模具鋼或718H模具鋼
        Non corrosive NAK80 die steel or 718H die steel
        硬模多用8407模具鋼,H13模具鋼,1.2344模具鋼。
        8407 die steel, H13 die steel and 1.2344 die steel are commonly used for hard molds.
        質量和精度要求高的,選用耐磨性和硬度好的模具鋼。
        Die steel with good wear resistance and hardness shall be selected for those with high quality and precision requirements.
        還有很多人按模具產量來分,其實按山東模具鋼小編個人想法的話,就會認為,除了試驗模,低端低量產模之外(一般指30萬次以內的模具),產量因素不應太大,真正高品質的產品,模具生產了50萬次跟沒生產時,產品的品質上肯定有差別。只是能否接受的問題。而這個段位的模具,用料基本都上了一定的等級。到達這一級別后,料與產量之比,不會太大。
        There are also many people who divide according to the mold output. In fact, according to the personal idea of Shandong mold steel Xiaobian, they will think that in addition to the test mold and low-end mass production mold (generally refers to the mold with less than 300000 times), the output factor should not be too large. For truly high-quality products, when the mold has been produced for 500000 times, there must be a difference in product quality. It's just a question of acceptability. The materials used for the moulds of this segment have basically reached a certain level. After reaching this level, the ratio of material to output will not be too large.
