(1)按離型劑的使用方式不同有外離型劑及內(nèi)離型劑之分。外離型劑是直接將離型劑涂敷在模具上;內(nèi)離型劑是一些熔點比普通模制溫度稍低的化合物,在加熱成型工藝中將其加入樹脂中,它與液態(tài)樹脂相容,但與固化樹脂不相容,在一定加工溫度條件下,從樹脂基體滲出,在模具和制品之間形成一層隔離膜。
(2)按離型劑的狀態(tài)不同有薄膜型(主要有聚酯、聚乙烯、聚氯乙烯、玻璃紙、氟塑料薄膜)、溶液型(主要有烴類、醇類、羧酸及羧酸酯、羧酸的金屬鹽、酮、酰胺和鹵代烴)、膏狀及蠟狀(包括硅酯、HK-50耐熱油膏、汽缸油、汽油與瀝青的溶液及蠟型)脫模劑。基中蠟型離型劑是應(yīng)用最廣泛的一類離型劑,價格便宜、使用方便、無毒,缺點是會使制品表面沾油污,影響表面上漆,漏涂時會使脫模困難。對于成型形狀復(fù)雜的大型制品常與溶液型離型劑復(fù)合使用。
(3)按離型劑的組合情況有單一型和復(fù)合型離型劑(包括組分復(fù)合和使用方式上的復(fù)合)。
(4)按離型劑的使用溫度有常溫型和高溫型離型劑,如常溫蠟、高溫蠟及硬脂酸鹽類。
(5)按其化學(xué)組成有無機離型劑(如滑石粉、高嶺土等)和有機離型劑。
(6)按其復(fù)用次數(shù)有一次性離型劑和多次性離型劑。
由于環(huán)氧樹脂對其它材料粘接力極佳,所以當需使用模具使環(huán)氧樹脂成型時都會遇到離型劑的問題。為了把已固化的制品順利地從模具上取下來,必須在模具的工作面上涂脫模劑。一方面可以使環(huán)氧樹脂制品表面光潔,另一方面保護模具不受損壞。
離型劑分為內(nèi)部潤滑性和外部潤滑性兩類。前者主要是提高聚合物分子本身的潤滑性,它要求與樹脂聚合物有一定程度的親和性或相溶性。后者是提高模具與聚合物之間的潤滑性。因而對它的選擇很重要,對離型劑一般要求如下:使用方便、干燥時間短;操作安全、無毒;均勻光滑,成膜性好;對模具無腐蝕,對樹脂固化無影響;對樹脂的粘附力低;配制容易、價格便宜。2100433B

“There is no other software out there that can compare to WorkNC.”
---John Bodine Business Owner
“沒有其他軟件可以和WorkNC相比。”
---John Bodine LB Mold的老板
For LB Mold, embracing technology isn’t just par for the course, but an essential part of the recipe for sustained success.
對LB Mold來說,擁抱技術(shù)是一種常態(tài),而且是其持續(xù)成功的關(guān)鍵因素。
“A distinct advantage that can easily get overlooked in manufacturing is not only having the best manpower or equipment, but the ability to intentionally and successfully integrate technology,” says John Bodine, owner of LB Mold, an Edinburgh, Indiana‐based whee‐mold manufacturing company.
“在制造業(yè)中容易被忽視的一個明顯優(yōu)勢,不僅是擁有最好的人力或設(shè)備,而且還能有意地、成功地整合技術(shù)?!蔽挥谟〉诎布{州愛丁堡的輪模制造公司LB Mold的老板John Bodine說。
Bodine says of his business philosophy, “We always have to be willing to take calculated risks —and perform calculated experiments -in order to be innovative and continue to push our standard upward.”
Bodine說他的經(jīng)營理念是:“我們一直愿意承擔(dān)風(fēng)險,將風(fēng)險進行評估并實踐,持續(xù)創(chuàng)新并向上推動我們的標準?!?/p>
LB Mold和WorkNC
LB Mold was established in 1996, after Bodine had accrued over 20 years of experience in the mold and pattern industry. Having been exposed to various lines of CAM software over the years, he knew that the WorkNC solution by Vero Software would be his system of choice. The solution was in place when LB Mold secured its very first customer.
LB Mold成立于1996年,經(jīng)過20多年的模具和模具行業(yè)經(jīng)驗積累。多年來,他接觸過各種各樣的CAM軟件,他知道Vero軟件的WorkNC解決方案將是他的選擇系統(tǒng)。當LB Mold獲得他的第一個客戶時,就采用了WorkNC解決方案。
“I would have had a lot more headache trying to run this business without WorkNC. It’s very dependable software,”Bodine says. “The wheel molds that we manufacture produce a very visual part of the automobile. There is no room for error.”
“如果沒有WorkNC,經(jīng)營業(yè)務(wù)會是非常頭疼的事?!?WorkNC是一個非??煽康能浖盉odine說?!拔覀冎圃斓能囕喣>咧圃炝似嚨囊曈X部件,沒有犯錯的余地。
LB Mold is a tier-two supplier that serves a customer base in North America. Despite being one of only a few American wheel-mold manufacturers to survive the auto industry’s instability in 2008 and 2009, Bodine concentrates less on world trends and more on business.
LB Mold是在北美為客戶服務(wù)的二級供應(yīng)商。在2008年至2009年,僅僅只有少數(shù)幾個美國輪胎制造商在汽車行業(yè)的不穩(wěn)定中幸存下來,Bodine卻很少關(guān)注世界趨勢,更多的關(guān)注其業(yè)務(wù)。
“Our work will speak for itself. There is a lot of noise that could easily distract you from doing your work,”Bodine says.“We choose to stay focused. When we focus on our customers, we are more apt to support them as they grow.”
“我們的工作將為發(fā)聲。有很多噪音很容易分散你的注意力?!?Bodine說。“我們選擇保持專注。”當我們關(guān)注客戶時,我們更傾向于支持他們的成長與發(fā)展。
With only a“couple small glitches having occurred in their nearly two-decade working relationship with WorkNC, Bodine reports that ongoing upgrades paired with strong customer support have helped to ensure the software’s irreplaceable role in his company.“There is no other software out there that can compare to WorkNC,”he says.
“在與WorkNC的20多年的工作關(guān)系中,僅僅出現(xiàn)了“小故障”,”Bodine說,“不斷升級的功能和強大的客戶支持有助于確保軟件在我的公司中有著不可替代的地位。沒有其他軟件可以和WorkNC相比?!?/p>
LB Mold與
In 2014, when LB Mold expanded its machining capabilities by adding two top-of-the--line 5-axis Mazak machining centers and acquired four new YCM 3-axis machines, it revisited how WorkNC could maximize its new equipment.
2014年,LB Mold增加了兩種頂級的5軸馬扎克加工中心和 4臺新的YCM 3軸機。他重新驗證了WorkNC如何最大化駕馭其新設(shè)備。
To test the company’s options, CNC Programmer and Lead Engineer Darren Wright sent component files to a handful of CAM companies to gauge their ability to program LB Mold’s most challenging components.
為了測試公司的選擇,CNC程序員和首席工程師Darren Wright將組件文件發(fā)送給了幾個CAM公司,以評估他們對LB Mold最具挑戰(zhàn)性的組件能力。
“WorkNC was the only one of the four or five companies that were sent part files that—a few hours after we sent the files—asked if we wanted to see a demo of the software with our parts,”Wright says. “The attentiveness to the customer’s needs (and our previous work history) made the decision easy for us.”
“WorkNC是這四、五家公司中唯一的一個,在我們發(fā)送文件幾個小時后,就回復(fù)文件,詢問我們是否想要用我們的部件來演示軟件,”Wright說。“WorkNC對客戶需求的關(guān)注(以及我們之前的工作經(jīng)歷)使我們的決策變得容易。”
LB Mold使用的WorkNC的優(yōu)勢
Two WorkNC features consistently utilized by LB Mold are its ability to apply sequences and its Auto 5 feature — a handy tool for a 3‐axis shop integrating 5-‐axis capabilities.
LB Mold一直使用WorkNC的兩個特性:序列功能和Auto 5——這是一個3軸集成5軸功能的便利工具。
Designed to further automate the programming process, sequences can be easily established by utilizing data from previously machined jobs.Sequences can be loaded to designate multiple machining operations, including all parameters, at once. For instance, a sequence for“hard steel finishing”can be used again and again to streamline the programming process.
為了進一步自動化編程過程,可以通過利用以前加工過的工作的數(shù)據(jù)輕松地建立序列??梢约虞d序列來指定多個加工操作,包括所有參數(shù)。例如,可以一次又一次地使用“硬鋼精加工”的順序來簡化編程過程。
Machining parameters may include speeds and feeds, as well as all tool parameters attached to the sequence. Utilizing sequences in WorkNC also ensures consistent programming among multiple users, as sequences aid in the recording and implementation of best practices throughout the shop.
加工參數(shù)包括速度、進給,以及所有附加在序列上的工具參數(shù)。在WorkNC中使用序列也確保了多個用戶編程的一致性,且序列有助于在整個車間記錄和實現(xiàn)最佳的加工方案。
“The ability to bring in sequences is something that I use all the time,” CNC Programmer David Fredericksen says. “If the job is similar to a previous job, I just bring in the sequences and apply them.”
CNC程序員David Fredericksen說:“我一直都在使用序列功能。如果在做的工件和以前的工件很相似,我就直接套用序列加工?!?/p>
WorkNC’s 5-axiscapabilities have also allowed LB Mold to eliminate a portion of lathe time previously required for some of its components. A component that previously required two operations on a lathe and one on a mill took two hours to machine. Those same operations can now be combined into one operation on a 5-axis machine, cutting machining time by 70 percent.
WorkNC的5軸功能還使LB Mold削減了一些零件以前需要的車床時間。以前需要在車床上進行兩個操作的組件,以及在磨機上進行一個操作,需要兩個小時的時間。這些相同的操作現(xiàn)在可以組合成一個在5軸機器上的操作,將加工時間減少70%。
WorkNC Auto 5 enables programmers to automatically generate collision-free 5-axis toolpath that is based upon existing 3-axis toolpath. It also takes into account the kinematics of the selected 5-axis mill. The 5-axis toolpath supports the use of short, rigid cutters and allows more of the job to be finished in one setup, reducing both machining time and human error.
WorkNC Auto 5使程序員能夠基于現(xiàn)有三軸刀具路徑自動生成無碰撞的5軸刀具路徑,并且自動考慮到選定的5軸機的運動極限。5軸的刀具路徑使得刀具更短,且剛性更強。并實現(xiàn)了一步設(shè)置完成更多工作。既減少了加工時間和也避免了人為出錯。
“Ten years ago, when we would machine the cosmetic side of a component, it would take 24 hours,” Wright says, “and now have it down to seven.”
Wright說:“十年前,當我們加工一個裝飾品的零件,它需要24小時,現(xiàn)在只需要7小時。”
Most importantly, after all the employees have gone home and the lights have been turned off, all the machines continue to run. They are able to utilize WorkNC for lights-out machining because of its reliability, and the accuracy of its toolpath verification, simulation, and collision detection.
最重要的是,所有的員工都回家了,燈都關(guān)掉了,所有的機器都在運轉(zhuǎn)。由于WorkNC的可靠性,刀具軌跡驗證、仿真和碰撞檢測的準確性,他們可以放心地在熄燈后加工。
WorkNC pinpoints collisions and out-of-limit conditions in a global machining environment that includes the machine, workpiece, fixturing, and complete tool assembly.
WorkNC在全局加工環(huán)境中準確地判斷出碰撞和極限條件,包括機器、工件、夾具和完整的工具組件的檢測。
“I’ve used a lot of software packages and WorkNC is the only package that, if it says it isn’t going to crash, it isn’t going to crash,” says Fredericksen. “We have an enormous investment in our equipment. When applicable, we have those machines running 24 hours a day. We can do this with confidence because of WorkNC.”
“我已經(jīng)使用了很多軟件,而WorkNC是唯一的一個,如果它說它不會碰撞,它就不會絕不會碰撞的,” Fredericksen 說:“我們對設(shè)備投資巨大。一旦投產(chǎn),就要確保機器每天24小時運轉(zhuǎn)。因為有WorkNC,所有我們可以信心十足地做到這一點。”
For LB Mold, lights-out manufacturing is a direct byproduct of making the most of its technology with WorkNC.
對于LB Mold來說,熄燈制造是充分利用WorkNC的技術(shù)的直接副產(chǎn)品。
“When I can get technology working for me, I’ve got a competitive edge that allows us to sustain success. WorkNC empowers me to compete and succeed in today’s global market,” Bodine says.
“當我能利用科技為我工作時,我就有了一個使我持續(xù)成功的競爭優(yōu)勢。WorkNC使我能夠在今天的全球市場上競爭并取得成功” Bodine說。
