Inyeksion qoliplarni qayta ishlash va ishlab chiqarish uchun qanday materiallar ishlatiladi?

We know that the quality of plastic processing and manufacturing injection molds depends to a certain extent on the materials it selects. Processing and manufacturing injection molds is an indispensable part of plastic molding and processing, and the proportion of the total mold output value is increasing year by year. According to statistics , The processing and manufacturing of injection molds accounts for about 33 percent of the total molding molds. Therefore, the application of processing and manufacturing injection molds is becoming more and more important in the national economy. The main factors affecting the life of plastic molds are: mold structure, mold material, mold processing quality, mold working conditions, product parts, etc. In the meantime, the characteristics of the mold material itself and heat treatment play a crucial role. Commonly used processing and manufacturing injection mold materials

Hozirgi vaqtda ko'pchilik karbonli po'latdan yasalgan qolip po'latlari arzon narxlari, qulay foydalanish va ma'lum mexanik funktsiyalari tufayli keng qo'llaniladi. Plastmassa qolipli po'latdan tashqari, u oldindan qattiqlashtirilgan plastik qolip po'lati kabi boshqa qolip po'latlarini ham o'z ichiga oladi. Ko'p qolip po'latlari mavjud. Hozirgi vaqtda ko'proq qo'llaniladigan qolip po'latlari orasida oldindan qattiqlashtirilgan plastik qolip po'lati, karbürizatsiyalangan plastik qolip po'lati va yoshga chidamli plastik qolip po'lati mavjud. Oldindan qattiqlashtirilgan plastik qolip po'lati po'latdan ishlov berish uchun oddiy qattiqlikdir, bu turdagi po'lat mukammal kesish ko'rsatkichlariga ega va to'g'ridan-to'g'ri kavitada ishlov berilishi mumkin.

Inyeksion qoliplarni qayta ishlash va ishlab chiqarish uchun material tanlash talablari

1. Ajoyib abraziv ishlash

Yuqori sifatli qarshi kalıplanmış mahsulotlar bo'shliq yuzasida kichik pürüzlülük qiymatini talab qiladi. Masalan, inyeksion qolip bo'shlig'ining sirt pürüzlülüğü Ra0.1-0.25 dan kam bo'lishi, optik sirt esa Ra bo'lishi talab qilinadi.<0.01nm. the="" cavity="" must="" be="" polished="" to="" reduce="" the="" surface="" roughness="" value.="" for="" this="" reason,="" the="" selected="" steel="" requires="" less="" material="" impurities,="" fine="" and="" uniform="" arrangement,="" no="" fiber="" orientation,="" and="" no="" pitting="" or="" orange="" peel="" defects="" during="">

2. Zo'r termal barqarorlik

Plastik qarshi qoliplari qismlarining shakli ko'pincha murakkab va söndürmeden keyin ishlov berish qiyin. Shuning uchun mukammal termal barqarorlikka ega bo'lgan materiallarni iloji boricha tanlash kerak. Plastik qolip issiqlik bilan ishlov berilganda, chiziqli kengayish koeffitsienti kichik, issiqlik bilan ishlov berish deformatsiyasi kichik, harorat farqi tufayli standart o'zgarish tezligi kichik, metallografik tartibga solish va qolib standarti barqaror va uni kamaytirish mumkin. yoki plastik qolip standartini ta'minlash uchun endi qayta ishlanmaydi. Aniqlik va sirt pürüzlülüğü talablari.
