【正文】 另一方面，為未 來的網(wǎng)絡(luò)為基礎(chǔ)的生產(chǎn)要求，顯然， PCC 控制系統(tǒng)更具競爭優(yōu)勢，所以我們有理由相信，PCC控制系統(tǒng)在未來將是發(fā)生在注塑機(jī)領(lǐng)域。 PCC的硬件功能，而且還體現(xiàn)在各種信號設(shè)計(jì)了許多專用的接口模塊，如高頻脈沖，增量式編碼器，溫度，稱重信號及超聲波信號接口模塊為工業(yè)用地。 寶成單個(gè)任務(wù)在不同的模塊準(zhǔn)備，用不同的編程語言，這意味著不僅在常規(guī) PLC 一直到人們熟悉的階梯的特點(diǎn)靈活選擇，指令表語言委員會可以繼續(xù)使用，但用戶可以使用更加高效和直觀的高級語言（ PL2020），這是一個(gè)完整的文字語言控制，基本熟悉語法的技術(shù)人員會感到一種似曾相識的感覺，這說明控制要求一個(gè)非常簡單的，直觀的。 作為一個(gè)結(jié)果，它會掃描應(yīng)用的周期同真正外部的控制周期之間的區(qū)別，以滿足實(shí)時(shí)控制的實(shí)際需求。 PCC 是其最大的特點(diǎn)是類似于大型計(jì)算機(jī)的分時(shí)多任務(wù)操作系統(tǒng)和多樣化的應(yīng)用軟件的設(shè)計(jì)。 另一方面，由于特殊工藝的不斷發(fā)展和推廣的位置控制精密模具的要求越來越高。 然而，閥芯位置是一個(gè)中間變量，因此控制精度稍差。 注射速度，保壓壓力，背壓是注射部分溶膠控制的三個(gè)變量直接影響其控制產(chǎn)品質(zhì)量的準(zhǔn)確性。 模具溫度是在接觸與產(chǎn)品模具型腔表面溫度，它會顯著影響充膜，冷卻和包裝過程。 在塑料加工中，溫度控制主要包括料筒，噴嘴和模具的溫度控制。第二項(xiàng)議案注射壓力，速度和位移的多級交換過程的控制系統(tǒng)。 為了提高注塑機(jī)控制系統(tǒng)和質(zhì)量水平更高的水平，比 PLC 控制系統(tǒng)的設(shè)計(jì)專門為中小型可編程計(jì)算機(jī)控制器（ PCC）的應(yīng)運(yùn)而生。 更先進(jìn)的控制方法是應(yīng)用計(jì)算機(jī)控制，就是建立一個(gè)閉環(huán)實(shí)時(shí)計(jì)算機(jī)控制系統(tǒng)。 這種結(jié)構(gòu)簡單的控制方法，然而，窮人的抗干擾能力，控制溫度也比較低。s hardware I / O channels in a single road, road, or dozens of way more than a decade as a unit module carried out dozens of pointtohundreds of thousands of pointpoint expansion and working. PCC in the industrial control powerful advantages, and demonstrate the programmable controllers and industrial control puters and DCS (Distributed Industrial Control System) technology, the development trend of convergence, although this is still a relatively young technology, but in its more e more and more application areas, it is increasingly demonstrating its potential for development can not be underestimated. For the injection molding machine, the current widespread application of the PLC control system, but as technology advances, personalized, customized products, growing demand for injection molding machine control requirements more plex, higher and higher precision, PCC as a more advanced control system, will gradually occupy a certain market share. On the other hand, for the future workbased production requirements, obviously, PCC control system more petitive edge, so we have reason to believe, PCC control system will be in the future take place in the field of injection molding machines. This information es from 【 Wishsino Plastic Injection Molding Company Website】 對注塑機(jī)的控制 現(xiàn)代塑料注塑機(jī)是一個(gè)典型的系統(tǒng)集機(jī)械，電氣和流體，此設(shè)備已形成 了復(fù)雜的產(chǎn)品，少的后處理，加工各種塑料的特性，自成立以來發(fā)展迅速，目前全過世界上的產(chǎn)品 80％用于加工塑料注塑成型機(jī)。 1 ℃ . Precise temperature control in precision injection molding that help improve product quality and availability of raw materials is a very important indicator. In the plastic processing, temperature control include barrel, nozzle and mold temperature control. Barrel temperature of the barrel surface heating temperature, due to relatively thick wall barrel, so the choice of thermocouple detection point is critical, and different test points on the temperature curve is a large difference. Therefore, parallel detection of doublepoint, namely, surface and deep in the barrel at the same time set the thermocouples, will be relatively stable temperature curve is conducive to temperature control accuracy. Nozzle melt temperature directly affects the passage of the shear flow, the quality of the products have a major impact, so the nozzle temperature control
