【正文】 Cooling technology at the same time, the operation is simple, to a certain extent, expanded the scope of use, production cost is low, the cooling technology allows manufacturers maximize economic benefits. 。 For soft type of plastic, the lower the temperature of the cooling system, the quality of the product, the influence of molding products In addition, the cooling system of injection mold products molding play a crucial role. Under the condition of reasonable operation, a fortable temperature, injection mold in the process of production to maintain the stability of the product shape, will bend plastic product lines, product shape to minimize the risk of damage. 2 injection mold cooling technology pulse cooling technology In recent years, the pulse cooling technology is gradually used in the production process of injection mold. Pulse cooling technology with the traditional cooling system there exist certain differences, the main is the cooling fluid flow of the injection mold for proper adjustment, adjust cooling fluid flow according to the temperature of the injection mold is how much of it can maximize the temperature of injection mold and die cooling fluid temperature difference of narrow, speed up the cooling time of injection mold, further enhance the efficiency of the production of plastic products. Pulse cooling technology, however, there are some shortings, mainly in the process of its application in operation there are multifarious, in order to keep the temperature of the injection mold balance, will increase the cooling technology in the middle of the pulse cooling technology distinction, and for each partition for cooling temperature detection. The CO2 gas cooling technology According to the conditions of application of the technology will mold production material replace with CO2 gas cooling technology to supporting the use of metal material, mold production in the process of CO2 gas injection, to reach the effect of cooling. CO2 gas cooling technology can enhance the efficiency of the production of plastic products, 黑龍江八一農(nóng)墾大學(xué)畢業(yè)論文（設(shè)計） 32 at the same time also can ensure the quality of its products, the cooling technology in the process of application need only will be closing the mold vent, pared with the traditional cooling technology of its operating structure is simple. However, CO 2 gas cooling technology in the process of practical application, its application range is small, use easily restricted. This is mainly due to two aspects, one is that if the application of CO2 gas cooling technology, the requirement for mold of metal, but its cost is higher, manufacturers not be monly use. Second, the application of CO2 gas cooling technology for technical talented person39。s life quality enhances unceasingly, for the quality of articles for daily use or style and so on various aspects demand increase gradually. At present, the plastic products are widely used in our daily life, with its novel appearance, easy to use, at the same time also includes reasonable price etc. Injection mold is one of the main methods of producing plastic products, the relevant technology of the cooling system is a central part of the injection mold, it decides the plastic product quality. 1 cooling system design and the quality of plastic products Cooling system technology the application of the plastic product quality has the key effect, in plastic injection molding process to ensure product mold under appropriate temperature. Mold temperature is too low, will influence the plastic molding products, product line deformation。 cooling system 。本文首先就冷卻系統(tǒng)技術(shù)對注塑模具產(chǎn)生的影響進行闡述，并且根據(jù)近年來我國新流行的幾種冷卻技術(shù)進行分析，通過對不同冷卻技術(shù)優(yōu)缺點的研究，認為隨形冷卻技術(shù)具有更大的發(fā)展前景，主要是該項冷卻技術(shù)具有較好的冷卻功能，能夠縮短模具的冷卻時間，提高生產(chǎn)效率；同時，冷卻技術(shù)操作簡單，在一定程度上擴大了使用范圍，該冷卻技術(shù)的生產(chǎn)成本低，能夠使生產(chǎn)廠家經(jīng)濟效益最大化。在此基礎(chǔ)上，隨形冷卻技術(shù)的應(yīng)用操作簡黑龍江八一農(nóng)墾大學(xué)畢業(yè)論文（設(shè)計） 29 便、生產(chǎn)成本不高，被越來越多生產(chǎn)廠家所青睞。要想取出塑料成品就要查看模具當(dāng)中的生產(chǎn)材料是否全部冷卻，冷卻不均勻極容易延長塑料成品的冷卻時間，影響其生產(chǎn)效率，最終影響企業(yè)的經(jīng)濟效益。在此基礎(chǔ)上，隨形冷卻技術(shù)還從根本上提高了塑料產(chǎn)品成型的生產(chǎn)效率。 隨形冷卻技術(shù) 隨著注塑模具冷卻系統(tǒng)相比較，技術(shù)的發(fā)展與應(yīng)用，隨形冷卻技術(shù)逐漸產(chǎn)生。這主要是由兩方面原因造成的，一是，若應(yīng)用 CO2氣體冷卻技術(shù)，要求模具為金屬材質(zhì)，但是其成本較高，一般生產(chǎn)廠家不予以采用。 CO2氣體冷卻技術(shù)能夠提高塑料產(chǎn)品的生產(chǎn)效率，同時還能夠保證其產(chǎn)品質(zhì)量，該冷卻技術(shù)在應(yīng)用的過程中只需要將模具的排氣孔予以關(guān)閉操作，與傳統(tǒng)的冷卻技術(shù)相比其操作結(jié)構(gòu)簡便。但是，脈沖冷卻技術(shù)還存在一定的缺陷，主要是其在操作應(yīng)用的過程中存在一定的繁雜性，要想保持注塑模具的溫度平衡性， 就要在脈沖冷卻技術(shù)當(dāng)中增加其冷 卻技術(shù)的區(qū)分情況，并且要針對每一個分區(qū)進行冷卻溫度的檢測。 2 注塑模具冷卻技術(shù) 脈沖冷卻技術(shù) 近年來，脈沖冷卻技術(shù)被逐漸應(yīng)用于注塑模具的生產(chǎn)工藝中。 產(chǎn)品成型情況的影響 此外，冷卻系統(tǒng)技術(shù)還對注塑模具的產(chǎn)品成型起到至關(guān)重要的作用。 塑料尺寸大小的影響 塑料被分為很多種，其中比較常見的是結(jié)晶型塑料和另外一種軟質(zhì)形塑料。 成型周期的影響 成型周期的長短是影響塑料產(chǎn)品生產(chǎn)效率的關(guān)鍵所在，注塑模具在進行出模操作的時候，其規(guī)定溫度為 8O℃左右，這些溫度只有極少一部分會流失到大氣中，但是有將近 75％的溫度需要依靠模具的冷卻系統(tǒng)技術(shù)來完成。 1 冷卻系統(tǒng)設(shè)計與塑料成品質(zhì)量的關(guān)系 冷卻系統(tǒng)技 術(shù)的應(yīng)用情況對塑料成品的質(zhì)量好壞具有關(guān)鍵影響，在進行塑料產(chǎn)品注射成型的過程中要確保模具處于恰當(dāng)合適的溫度下進行。目前，塑料制品被廣泛應(yīng)用于我們?nèi)粘Ｉ钪?，其具有外觀新穎、使用方便， 同時還包括價格合理等特點。文章主要從注塑模具的冷卻系統(tǒng)相關(guān)技術(shù)進行闡述分析， 為注塑模具的產(chǎn)品開發(fā)以及技術(shù)應(yīng)用提供參考。 最后，再次向在本次設(shè)計過程中給予我細心指導(dǎo)和幫助的各位老師表示衷心的感謝，感謝老師在百忙中給予我極大的幫助，使得我這次設(shè)計得以順利完成。 通過這次設(shè)計我深深體會到光學(xué)會書本中的知識是遠遠不夠的，在實際工作中我們還需要積累更多的經(jīng)驗，特別是對于我們即將走向工作崗位的大學(xué)生來說，實際 經(jīng)驗更為重要，它是一筆寶貴的財富。不僅使我掌握了基本的研究方法，還使我明白了許多待人接物與為人處世的道理。 她 嚴謹細致、一絲不茍的作風(fēng)一直是我工作、學(xué)習(xí)中的榜樣； 她 循循善誘的教導(dǎo)和不拘一 格的思路給予我無盡的啟迪。 黑龍江八一農(nóng)墾大學(xué)畢業(yè)論文（設(shè)計） 25 參考文獻 [1] 王先逵 .《機械制造工藝學(xué)》 [M].第二版，北京：機械工業(yè)出版社， 2021.
