肥皂盒注塑模具設計畢業(yè)設計論文(編輯修改稿)

　

【文章內容簡介】 孔之后要離型芯的下表面有1015毫米的距離，離型芯的上表面也要保持1015個毫米的距離。具體體現如下圖所示： 冷卻水線圖 冷卻時間的確定，在注射過程中，從塑件開始充型到充型結束并且能吧塑件此乃型腔中取出的這段時間定義為冷卻時間。這個時間標準通常是以充分固化定型，而且保證了制品具備一定強度和剛度為依據，它占到整個注射生產周期的80%，這個時間和制品的壁厚的材料有著直接的關系，材料為pvc，查課本《塑料成型工藝及模具設計》第210頁。第九章 模具的裝配 模具裝配前準備工作：對照總裝配圖對裝配的基準做好把握，接下來檢測每個零件，吧不符合要求的零件淘汰掉，至于合格零件要去磁，假如零件組合后有尺寸上滿的誤差則說明要進行修模的的工作。分型面的吻合面積不能少于80%，間隙不能超過溢料量的極小值，裝配時要盡量保持原有的加工尺寸基準面，組裝每個系統(tǒng)時保證沒有卡滯、松動的現象產生，組裝時要保證所有的定位螺釘定位銷、連接螺釘緊湊，再試模，吧杜荷要求的零件做好標記，并且標記好組裝基準面。（1）每個零部件，動模和定模都需要分開裝配，再總裝。（2）裝配導套導柱機構時需要保障開合模的動作輕靈沒有晃動阻滯現象的發(fā)生。（3）裝配型芯、鑲件，應根據實際情況進行必要的修模使各配合間隙達到預定要求。（4）在裝配頂出系統(tǒng)時由于我們設計的頂出系統(tǒng)是多頂桿頂出系統(tǒng)需要調整復位，頂出等裝置。（5）裝配冷卻系統(tǒng)，要檢測水路通暢沒有阻塞，漏水電以及閥門是否靈活。（6）在裝配傳動系統(tǒng)（液動和氣動）管路之間的連接是否合格。（7）固定連接螺釘是施加的力量要均勻，緊固可靠，保證模具裝配齊全。（8）檢查模具所用的各種配件，附件等，保證模具裝配齊全。總結 在畢業(yè)設計過程中，確實遇到了大大小小的問題，但是通過問題的一個個解決，使我對知識的理解和把握有了很大的提高。通過查找資料的過程中，使我對模具這方面的知識有了新的認識和理解，模具是一個高附加值技術密集的產業(yè)，我們國家的制造業(yè)發(fā)展迅速，這對模具提出了新的要求，所以說模具技術的提高與開發(fā)大有文章可做。畢業(yè)設計是我們大學這四年來，對所學知識的運用和遷移能力的一此考驗，也是對我們在校期間所學的一次總結與應用，更能提高我們解決問題的能力。剛剛拿到畢業(yè)設計這個題目的時候，我真的是無從下手，因為我是學機制的，對于模具方面的知識真的接觸的不是很多，運用到的軟件也不是很熟練，而真正在設計過程的這些問題也是凸顯得很明顯，在這樣的情況下我能做到的就是通過去問老師、懂這方面知識的同學和去圖書館借閱書籍來解決問題，我想這個思路是完全正確的，應為對于不懂的東西問那些有經驗的人，可以讓我們少走很多的彎路，從而節(jié)省出很多的時間和精力。 在這里我要感謝周慧蘭老師的耐心指導，因為設計中遇到的問題真的太多，我做事太毛躁加之前期沒有抓緊，導致在后期的工作量很繁重，不得不多次打擾到老師。但是在老師的指導下通過問題的提出與解決，使我對這方面的知識有了更深的理解，并且學習到了更多的新知識。就是在這樣的一個過程中我重新的認識了自己，對自己有了新的定位和要求，在一些方面樹立起來了信心，在對于我來說都是有著不言而喻的意義。參考文獻 [1] 葉久新 ，2008 [2] 王玉甲 張忠林等主編. ，2003 [3] 周慧蘭 ，2009 [4] 肖乾 ，2011 [5] 陳學銘 ，2009 [6] 洪亮 ，2010 [7] 吳兆祥 ，2002 [8] 詹友剛 ，2007[9] 付利 ，1997[10][J].[11]張杰. ，[12]，[13]陳世煌， [14] forming and molds[J].Die and Mould technology,2003,5.[15] Yung K l,Liu H,Xu Y,Target tracking in micro injection molding[J].Key Engineering Materials,2008.附錄A外文翻譯Injection Mold Design Plastic industry is an industry of rapid development in the world today is among the few one of billions of dollars in industrial production. Plastic products in daily life provides great convenience for people, including soap box is almost essential supplies. This paper designed a soap box, have waterproof function, can effectively protect the soap does not get wet by water, prolong the service life of the soap.Injection mold forming method because of its high efficiency, high precision, low cost of producing a variety of products with plex shape, is the importance of plastic products production means. However, facing the globalization market petition, the plastics industry is faced with great pressure. In order to shorten product design cycle, improve product quality, will all kinds of advanced production mode is used in the design of the injection mould is the trend of The Times, such as CAD/CAM/CAE integration technique. This paper can be seen from the diagram, the plastic pieces belong to the thin walled cavity products, projection area of the highest plane for the box of the plane, so the parting surface should be selected in the soap box holds the biggest projective planes. Cavity number for one module and four cavities, gate in the bottom of the box edge, USES the gate. According to the structure of plastic parts and mould, selection of mold for the two templates. Set the channel 8 mm diameter, the distance from plastic parts for around 10 mm, thimble and insert the minimum distance of 8 mm. Move set mold cooling alone, mold cooling water flow driven template into, after flowing through the core driven templates, templateBetween the core and equipped with rubber gaskets to prevent leakage, mold parts and dynamic model. The plunger diameter is 8 millimeter, each cavity has four. Installed at the bottom of the core of the mainstream way to pull rod material, diameter of 8 mm. Thimble and pull rod and the mold cavity.According to the characteristics of the plastic parts, the whole embedded mold. Considering the distribution of cooling water channel and template of the screw hole, guide pin, guide sleeve, etc., to estimate the mould size horizontal plane projection, find out similar die set from the standard. This die set on the basis of LKM gate mould frame, the die setThe determination of the specific parameters such as table mold cavityThe determination of the most economic cavity number is essentially plastic pieces of economic accounting of the cost of production. butIn the initial stage in injection molding design, technical parameters such as pouring system is unknown, this cavityIs a kind of estimate forecast, establishing thumb first assumed that after pletion of the mold design, e inCost accounting. Therefore, carries on the prehensive consideration, the balance of the early set with one module and four cavitiesType cavity layout, the design of gating system and pouring system refers to the injection mold from the beginning of the end to the mainstream way in the cavity between the melt feeding channel, gating system design is also a key link in the design of injection mould, its design is reasonable or not will affect the quality of the plastic products. The role of the gating system is made from injectionDie jet nozzle of the plastic melt smoothly and successfully, paction and pressure. This design USES the balanced type is decorated, circular cross section distribution.Choose the form of a gate for direct gate, because the wall thickness is 1 mm, so choose contact parts of the gate to 1 mm wide. The generated gate, flow products and in people39。s everyday lives of modern industrial production has been increasingly widely used. With the development of the plastics industry, the social demand for plastic products, getting bigger and bigger. According to statistics, in modern industrial production, 60% to 90% of industrial products require the use of mold, mold industry has bee the foundation for industrial development [2]. The plastic injection molding in a mold growing share of the weight, and its development is very rap
