模具上的“行位”用英文怎么表达？

Slide 行位,(总称)

Slide block 行位块(主体)

Slide insert 行位镶件,

另给些资料参照:

1． XXX！你现在有空吗，我可以问你一些问题吗？

Could I ask you some questions if you are free?/ Are you free now? May I ask you some questions (a

question)?

2． 请问此产品的面是否为外观面？表面做什么处理？是晒纹/抛光？

Can you tell me whether the surface of this part is a visible/esthetic one? What will we do for its

surface? Texture or Polishing?

3． 请问产品这个面可否加顶针或顶块？产品允许加扁顶针吗？

Does this part need an ejector pin or an ejector bar? Can we add an ejector blade?

4． 这个产品的柱位我们打算做司筒。（或镶针）可以吗？

Can we add ejector sleeves or ejector pins in the boss of this part?

5． 产品的这个位置不能出模，我们打算做行位，在此面上会有分模线，你接受吗？

There's an undercut at this position and it needs a slider. It will also have a parting line on

this side, is that OK?

6． 产品里面的这个位置我们打算做斜顶或内行位，有问题吗？

We will make the lifter and (inner) slider in this position, will that be a problem?

7． 你提供的2D产品图与3D产品图不一致，请问以哪一个图面为准？

The 2D and 3D drawing you provided is not the same, can you tell me which one is correct?

8． 你提供的3D产品图有的地方没有出模角，有的地方胶位太厚，有的地方胶位太溥，这些产品问题我们可以自

己修改吗？修改后会给交给你确认。

There is no draft angle in the 3D drawing, some materials are too thick, and some place are too

thin. Can we modify this part by ourselves? We will send the drawing to you for you to check after

we modify it.

9． 按你们提供的缩水率千分之五，这个模具的尺寸已经做到了模具图面要求。但注塑出来的产品不符合你们的

产品图。

请确认你们的材料的缩水率是否正确？

Accoring to the shrinkage one over two hundred, the mold has been done in the right dimension, but

the part falls short to your part drawing, are you sure the shrinkage is right?

10． 产品的这个位置太小，导致模具钢料太溥，能够加宽这个位置吗？

This position is too **all and will make the steel material here too thin, can we widen it here?

11． 斜顶与后面的柱位空间太小，斜顶在运动时会干涉到柱子，能移动这个柱子的位置吗？

The angular lifter interferes with the boss during ejection. Please consider changing the position

of the boss.

12． 这个筋骨位胶厚太溥，而且高度偏高，注塑时很难填充这个筋位，可以增加这个筋骨位的厚度吗？

The rib here is too thin and on the high side, so it will be difficult to fill here when we do the

injection, can you inrcease the thickness of this rib?

13． 你是想将此筋骨位的高度加高/减低吗？加胶的位置我们将用铜公放电加深。但减胶的位置有两种做

法，1、做镶件；2、烧焊；因为镶件的底部有运水，我们简单的做法是烧焊处理，你可以接受吗？

Will you increase/decrease the material on this rib? We will use EDM if you add material, but there

are two option if you choose to decrease:1.Make inserts;2.Welding, because there is water in the

bottom of the insert, is that OK?

14． 这个样板的筋骨位底部烧焦，是因为排气不良，我们可以在筋骨位的中间增加一个镶件。

This sample has been burned in the bottom because the venting is not good, we can add an insert in

the middle of the rib.

15． 重做镶件大约需要5-6天时间，你能接受吗？

It will take about 5 or 6 days to redo the insert, is that OK?

16． 产品的这个面我们已经做了晒纹处理，如果需要加胶，这个面我们需要重新外发晒纹。可能需要几天的时间

。

所以我们直接以铜公放电的火花纹取代你要求的纹路，你可以接受吗？

We have made the texture on this side, if we add material, it will take some days to remake the

texture by out-resourcing, so we suggest using the texture by EDM instead, is that OK?

17． 模具是用公制/英制的配件？需要备用件吗？

Is this mold dimension measured in inches or meters? Does it need spare parts?

18． 模具上铭牌上的刻字内容是由你们提供吗？你们什么时候可以这些刻字资料。

Will you provide the engraving content of the plate of this mold to us? When will you send it?

19． 可否提供此模具生产时，注塑机的型号及相关资料。如：啤机大小、呵林柱尺寸、顶棍孔尺寸等

Can you provide the type of injection machine and other related information of this mold to us?

Such as the boss dimension, the hole's dimension of the ejector pin and the size of the injection

machine and so on.

20． 这个问题我需要同其它同事商议会再答复你。

I need to discuss this problem with the other colleagues and then I will reply back to you.

21． 我们将尽力达成你的计划，如有异常，会及时通知你。

We will try our best to complete your plan, if there are any complications, we will notify you

immediately.

综述

An ancient sport as old as mankind, embodying the most directmanifestationof human strength。

weightlifting has not onlyflourished,but also developed into a modern sporting discipline for the 21st century。

The apparent simplicity of lifting thebarbellfrom the ground and over the head in one or two movements is deceiving。

Weightlifting requires a combination of power, speed, technique, concentration and timing。

Super heavyweight lifters normally claim the title of World’s Strongest Man or Woman。

However, kilo per kilo, the lightest weightlifter is often the strongest。

Men’s weightlifting was on the programme of the first modern Olympic Games in Athens in 1896。

litter lifters 具体应该翻译成什么呢？

小小垃圾升降机嘛

就是在描述这些孩子，环保，爱护环境的。内容标题就是对孩子们特殊身份的比喻。知道这些就可以了。

不用死命地把它硬翻译出来。知道意思就OK了。

这是什么摩托车，最好详细点

应该是出售本田瓦尔基里1520cc（又称大瓦，大排骨，·维京人）

带有倒档

净重为 682磅，或者说是309公斤，根据本田的数据，这款巡航车当之无愧地成为重量级的车。

拇指在大尺寸的启动按钮上轻轻一按，就听到了那熟悉的六缸金翼的声音。尽管车身较大，瓦尔基里还是容易上手。有了这款车，本田达到了巡航车尺寸的极限。我们原以为雅马哈的皇家之星很大，但现在发现瓦尔基里和它一样的大。

除了宽大的手柄之外，这部车有许多金翼摩托车的感觉。由于发动机配置的物理限制，许多要改变的地方都不能实现。

比如，本田的设计者想把骑乘姿势做成脚在前的风格，就像在Shadow（幻影）系列，骑手的脚和腿前倾，所以他（或她）的足尖和车架平行，在发动机的前面。但每边一组三个突出的气缸使得骑手的腿无法放到前缸的前面，所以脚蹬不得不放到气缸的后面。而且是足够的远，以使脚不会碰到任何一个后缸。所以骑手的腿只能是一种坐直的姿势。实际上，驾驶位置也是一种自然的位置，为长途驾驶提供尽可能的舒适。

最印象深刻的时，一旦你适应了大车身的感觉以后，你就会很想在路上好好的试试身手。感觉就像是骑了一部大手柄的金翼，而且没有整流罩。经过转弯的时候，Valkyrie 一冲而过，没有任何的问题。

巨大的46mm的倒立前叉和双后避振能很好地吸收震动。所有的巡航车都有一个小缺点 (所有的这些巡航摩托车中，没有一辆的转弯技术设计的很好) ，而本田是一个意想不到的例外。那些大而宽的轮胎以及大而厚的悬挂元件能胜任一切，你只要试着踩下脚蹬就行。

这款庞大的六缸大块头的另外一个局限，是它的动力特性。本田对它的发动机做了较大的改动，包括固体提升器（solid lifters）,不同的凸轮，以及六个独立的镀铬的化油器的配合。一切的一切，这些不同没有造成与金翼发动机动力特性太多的不同。

它的动力输出十分的平滑，一直到它每分钟 6,250 转的红线区域。

配备了5档的齿轮，而且各档之间分布很好。当以每小时75英里（120公里）巡航时，转速表是每分钟3000转，一点儿的震动都没有。

双前碟刹十分的有力，轻巧地拉住了行驶中的摩托车， 悬挂足够的紧，以至刹车的猛冲没有任何问题。后刹车不是最有效的。

它没有金翼车的电动倒档齿轮，- 所以这部车的整体重量降下来了。同时希望所有的瓦尔基里车主小心停车。这部大车在低速时很容易操纵，但很笨重。瓦尔基里作 U型倒转就像在森林里遇到一头灰熊。不作任何突然的移动，你不会有任何的问题。

这里是大多数巡航车骑手所像要的牛肉。他们要的是在高速公路上以75英里（120公里）快速行走的摩托车。

虽然Valkyrie是高速的摩托车, 但它仍然是优雅的。这已经是本田所生产的最后的巡航车。它的价格非常的正确，比雅马哈的皇家之星低了一大块，这款车太平滑、太好操纵、太舒适了。

所以这款1520cc 的六缸高速巡航车是本田所承诺的全部，甚至更多。它的缺点是没有缺点。它是独一无二的。它的巨大的六缸发动机用于巡航实在是太平滑了。

Removing and Collecting Plastic Mulch The use of plastic mulch is a common practice for strawberry and vegetable growers, but there are two major problems with plastic mulch: it is expensive to install and at some point it has to be removed from the field. Several machines can help simplify removing it. Traditional Methods The traditional method of removing plastic mulch was to first loosen the mulch from the “cup” on each side of the bed by passing a cultivator sweep under the cup and then pick up the mulch by hand. Picking up mulch by hand is a filthy and strenuous task. Mulch Lifters Several companies now offer mulch lifters (Figures 1 2) that do a better job of loosening the plastic mulch than a simple sweep. These lifters typically have coulters that run beside the beds to cut any weeds or plant residue and loosen the soil, followed by one-sided blades that run under the cup and under much of the bed to further loosen the soil and lift the plastic mulch. Guides on the back of the blades lift the plastic in the air to allow the loosened soil to fall off. Some of the soil tends to fall back onto the center of the plastic sheet, making the plastic difficult to pick up. A coulter running down the center of the bed slices the plastic strip in half, allowing the soil on the center of the plastic to fall through when the plastic is later picked up. Plastic Collection After the plastic is loosened and lifted, some growers pick up the plastic by hand; however, there are several machines available to pick up the plastic. The most common design has a powered spool to roll up the plastic (Figure 3). In most cases, a worker has to tie the strip of plastic to the spool at the beginning of the row and then the plastic can be rolled up.
