2，湿坯转移模无法准确地与吸滤成型模具进行合模，每次合模误差很大，经常造成湿坯被撕裂，或湿坯不能正常被移交到湿坯转移模实现正常转移。
3，湿坯转移模与吸滤成型模具进行合模时，撞击太大，湿坯转移模在竖直方向的定位较难实现。
4，湿坯转移模在把湿坯移交给热压模具时，因行程过冲而无法控制湿坯转移模与热压模具之间的相对距离，在移模湿坯时造成湿坯周边的纤维溅到热压模具的型腔外，产生大量毛边，溅到热压模具上的纤维因不能及时被清除而变成焦炭、污染热压模具。
5，油缸推动湿坯转移模在进行上下移动时经常出现爬行现象，运动常出现抖动，很不平稳，油缸活塞杆的密封损坏后，油缸里面的液压油外泄经常污染浆液。
6，湿坯转移模上下移动速度非常缓慢，而湿坯转移模上下移动距离又往往很长，大大影响产量。

 具体实施方式
本发明的思路是：采用固定着转移模直线导轨2.4的滑柱2.3来带动湿坯转移模2.1作竖直上下运动，且滑柱2.3固定在湿坯转移模2.1的中心位置，可保证湿坯转移模的上下移动精度，减少湿坯转移模2.1上下运动的摩擦阻力，为快速上下移动提供了可能，同时又保证了湿坯转移模的重心不偏离滑柱2.3的中心线，保证了湿坯转移模与吸滤模的平行度，提高了湿坯转移模2.1上下运动的稳定性和定位的精准度。采用上下相隔一定距离的2组（或多组）转移滑块2.5对固定在滑柱2.3上的转移模直线导轨2.4进行导向完全能确保滑柱2.3上下运动精度和运行的稳定性，从而保证了湿坯转移模2.1与热压模具合模的准确性及上下运动的平稳性。由伺服电机通过齿轮齿条的传动或通过丝杠螺姆副的传动驱动滑柱2.3和湿坯转移模2.1进行上下运动，更大大地提高了湿坯转移模2.1上下运动的平稳性和上下定位的准确性；伺服电机的驱动可使湿坯转移模2.1精确快速运动，缩短了湿坯转移周期，可大大地提高制品产量。且还可大大提高产品的质量；也解决了湿坯受液压油的污染问题。
由于湿坯转移模及其附件有一定的重量而产生下拉重力，会产生较大的向下拉力，这是湿坯转移模失控下滑的动力因素，而且成为伺服电机带动湿坯转移模向上运动的强大阻力，为了解决这一问题，采用平衡气缸，或者采用一定重量的转移模重量平衡块来克服湿坯转移模及其附件的重量。这样彻底消除了因湿坯转移模及其附件的重量而使湿坯转移模失控下滑的动力因素；带刹车的伺服电机驱动滑柱2.3带动的湿坯转移模又可完全保证不让湿坯转移模失控下滑。
以下结合附图所示的实施例进一步说明。
实施例
如图1所示，植物纤维模塑成型机包含吸滤成型装置1、湿坯转移装置2、机架（上机架3；下机架4；拉杆5）。吸滤成型装置 1含有吸滤成型模具1.1、浆槽1.2，吸滤成型模具1.1真空抽吸浆槽1.2中的浆液，把浆液制成湿坯；机架由拉杆5、下机架 4和上机架 3组成，拉杆5把上机架 3固定在下机架 4之上，让上机架 3与下机架 4保持一定距离；吸滤成型装置1设置在下机架4中，湿坯转移装置2处于吸滤成型装置1的上方，湿坯转移装置2的湿坯转移模2.1可以竖直上下移动，以实现把吸滤成型模具1.1中的湿坯从吸滤成型模具1.1中移出。当湿坯在吸滤成型模具1.1中被制成以后，湿坯转移模2.1竖直下移与吸滤成型模具1.1进行准确地合模，合模时，湿坯转移模2.1接通真空产生负压，把吸滤成型模具1.1中的湿坯吸起，然后湿坯转移模2.1带着湿坯竖直上移，湿坯从吸滤成型模具1.1中被移出，又被送往下一道工序进行干燥或作其它处理。由于湿坯还没有被固化定型，在转移湿坯的过程中，如果湿坯转移模2.1与吸滤成型模具1.1的合模精度不高或湿坯转移模2.1上下移动不稳定，则湿坯容易破损和产生裂纹。所以，湿坯转移模2.1上下移动要做到以下几点，1，湿坯转移模2.1竖直下移与吸滤成型模具1.1进行准确合模；2，湿坯转移模2.1上下竖直移动要稳定、位移要准确、速度的快慢切换要平稳；3，滑柱2.3要固定在湿坯转移模2.1的中心位置，避免湿坯转移模因重心偏离滑柱2.3的中心线而导致湿坯转移模失去平衡而产生湿坯转移模与吸滤模的不平行现象，4，湿坯转移模2.1可稳定、精确地停留于竖直方向上的某一指定位置。湿坯转移装置2的性能要符合上述要求。
如图3、图3.1所示，湿坯转移装置2，包含湿坯转移模2.1、湿坯转移模安装板2.2、滑柱2.3、驱动湿坯转移模2.1和滑柱2.3进行上下运动的伺服电机驱动装置2.11。
如图1、图2、图2.1所示，滑柱2.3定位在上机架3上，且处于吸滤成型装置1的正上方，滑柱2.3可相对于上机架3进行竖直上下滑动，湿坯转移模2.1固定在湿坯转移模安装板2.2上，用来固定湿坯转移模2.1的湿坯转移模安装板2.2固定在滑柱2.3的一端，也可以把湿坯转移模2.1直接固定在滑柱2.3的一端，而不需要湿坯转移模安装板2.2，但湿坯转移模的重心与滑柱2.3的中心线重合。
如图1、图3、图3.1所示，滑柱2.3上装有可在转移滑块2.5上进行上下滑动的转移模直线导轨2.4，转移滑块2.5固定在上机架3上。转移模直线导轨2.4是一种直线导轨，转移滑块2.5与转移模直线导轨2.4进行相对直线滑动。滑柱2.3依靠转移模直线导轨2.4可在固定于上机架的转移滑块2.5上进行上下直线移动。具有很好导向性的滑柱2.3保证了湿坯转移模2.1上下移动时的运动精度，在滑柱2.3的导向和带动下，湿坯转移模2.1可稳定地进行竖直上下直线运动；转移模直线导轨2.4与转移滑块2.5之间进行的上下直线滑动减少了湿坯转移模2.1上下运动的摩擦阻力，为快速平稳的上下移动提供了可能。
如图3.3所示，转移滑块2.5与转移模直线导轨2.4之间的直线移动是相对的。可以反过来，把转移模直线导轨2.4固定在上机架3上，滑柱2.3上装有转移滑块2.5，则滑柱2.3通过转移滑块2.5可沿转移模直线导轨2.4进行上下直线移动。
为了增加滑柱2.3的导向效果和稳定性，如图3、图3.1、图3.3所示，所述转移滑块2.5分为上下二组或多组，相邻的上下二组转移滑块2.5之间相隔一定距离，固定在滑柱2.3上的转移模直线导轨2.4，在相隔一定距离的上下二组或多组固定于机架的转移滑块2.5上进行上下滑动；或者，固定在滑柱2.3上的相隔一定距离的上下二组或多组转移滑块2.5，在固定于机架的转移模直线导轨2.4上进行上下滑动；这样大大地提高了滑柱2.3的导向性，从而实现湿坯转移模2.1上下运动的平稳性和上下定位的准确性。
湿坯转移模2.1（或加上湿坯转移模安装板2.2）有一定的重量，采用固定着转移模直线导轨2.4的滑柱2.3来带动湿坯转移模2.1作竖直上下运动，滑柱2.3要固定在湿坯转移模2.1的中心位置，湿坯转移模的重心不偏离滑柱2.3的中心线，避免了湿坯转移模因重心偏离滑柱2.3的中心线而导致湿坯转移模失去平衡而产生湿坯转移模与吸滤模的不平行现象，从而从结构上充分保证了湿坯转移模与吸滤模的平行度。所以，滑柱2.3应安置在吸滤模的正上方。
湿坯转移模2.1（或加上湿坯转移模安装板2.2）和滑柱2.3有一定的重量，而该重量产生的重力施加于滑柱2.3和湿坯转移模2.1，并成为湿坯转移模2.1竖直向上运动的阻力。为克服这一重力，特地设置了平衡气缸来平衡湿坯转移模、湿坯转移模安装板和滑柱的重力，如图1.1所示，平衡气缸2.13固定在上机架3上，平衡气缸2.13的活塞杆与滑柱2.3连接在一起并且两者轴线相互平行，平衡气缸2.13的拉力与湿坯转移模、湿坯转移模安装板和滑柱的重量相匹配。以实现平衡气缸2.13的拉力来平衡湿坯转移模2.1、滑柱2.3以及湿坯转移模安装板2.2的重力。
也可以采用转移模重量平衡块2.6来平衡湿坯转移模、湿坯转移模安装板和滑柱的重力。如图1、图2、图3所示，在滑柱2.3的上方设置一组定滑轮（或链轮）2.10，定滑轮（或链轮）2.10可转动地定位在上机架上，滑柱2.3位于定滑轮（或链轮）2.10的一侧，有一定重量的转移模重量平衡块2.6位于定滑轮（或链轮）2.10的另一侧，如图3所示，重量平衡连接线（或者是链条）2.9跨过定滑轮（或链轮）2.10把转移模重量平衡块2.6和滑柱2.3连接在一起，重量平衡连接线2.9是一种柔索，它可以是绳、钢索、链条等。就这样，重量平衡连接线（或链条）2.9把转移模重量平衡块2.6和滑柱2.3分别挂在定滑轮（或链轮）2.10的两侧，转移模重量平衡块2.6通过跨过定滑轮（或链轮）2.10的重量平衡连接线（或链条）2.9拉着滑柱2.3，以实现转移模重量平衡块2.6的重力来平衡湿坯转移模2.1、滑柱2.3以及湿坯转移模安装板2.2的重力，就这样，可以使滑柱2.3和湿坯转移模2.1上下运动自如，有效地增加了滑柱2.3和湿坯转移模2.1上下运动的平稳性，转移模重量平衡块可有效地平衡湿坯转移模2.1及滑柱2.3的重量，不但消除了湿坯转移模2.1失控下滑风险，而且几乎消除了湿坯转移模2.1上下移动时的重力负载。重量平衡连接线（或链条）2.9和定滑轮（或链轮）2.10可以分别采用链条和链轮，也可以是有一定强度的绳或钢索与相配套的定滑轮。所述转移模重量平衡块2.6、平衡直线导轨2.7、平衡滑块2.8、重量平衡连接线（或链条）2.9、定滑轮（或链轮）2.10可以是一组也可以是多组。
当湿坯转移模2.1下行时，在重量平衡连接线（或链条）2.9的拉动下，转移模重量平衡块2.6上升；当湿坯转移模2.1上行时，转移模重量平衡块2.6靠自身的重力下行。
如图1、图3、图3.1、图3.2所示，已经实现了上下滑动且几乎处于重力平衡状态的滑柱2.3的上下运动是由伺服电机驱动装置2.11来实现的，所述伺服电机驱动装置2.11含有齿条2.11-1、齿轮2.11-2、伺服电机2.12。在滑柱2.3上固定有齿条2.11-1，齿轮2.11-2与齿条2.11-1相啮合，齿轮2.11-2由伺服电机驱动。伺服电机的转动带动齿轮2.11-2的转动从而带动齿条2.11-1和滑柱2.3一起上下移动；也可以是所述伺服电机通过丝杠螺母副的传动，来实现滑柱2.3和湿坯转移模2.1一起上下移动；也可以是所述伺服电机通过同步带的传动来实现滑柱2.3和湿坯转移模2.1一起上下移动。
在伺服电机2.12的驱动下以及在转移模直线导轨2.4的导向作用下，湿坯转移模2.1可稳定地、精确地进行竖直上下直线运动或稳定地、精确地停留于竖直方向上的某一指定位置。
如图3所示，为了防止转移模重量平衡块2.6在上下移动时出现摆动现象，转移模重量平衡块2.6可上下移动地定位在平衡直线导轨2.7上，重量平衡块2.6的上下移动是沿平衡直线导轨2.7进行的，从而保证了重量平衡块2.6的上下直线移动而不会产生摆动现象，增加了重量平衡块2.6上下移动时的稳定性。让转移模重量平衡块2.6沿平衡直线导轨2.7进行上下滑动，转移模重量平衡块2.6上固定着平衡滑块2.8，重量平衡块2.6通过平衡滑块2.8可上下移动地定位在平衡直线导轨2.7上，从而保证了重量平衡块2.6的上下直线移动，平衡直线导轨2.7也是直线导轨。与平衡直线导轨2.7相对滑动的平衡滑块2.8为线性滑块。也可以是，转移模重量平衡块2.6套在直线轨道上进行上下滑动。
有了所述的转移模重量平衡块2.6，在伺服电机2.12的驱动下以及在转移模直线导轨2.4的导向作用下，湿坯转移模2.1的竖直上下移动可做到快速、平稳、定位准确等要求。
吸滤成型装置1的吸滤成型模具1.1在浆液中吸滤一定的时间后露出液面，制成制品的湿坯，吸滤成型装置将浆液制成制品的湿坯后，湿坯转移装置2中的滑柱2.3带动湿坯转移模2.1竖直向下移动，把湿坯从吸滤成型模具1.1中吸起后，然后湿坯转移模2.1带着湿坯上升，把湿坯移出吸滤成型模具1.1。
含有湿坯转移装置2的植物纤维模塑成型机的几种形式举例如下。
图2所示的，是含有所述湿坯转移装置2的全自动双热压植物纤维模塑成型机，当吸滤成型装置1完成湿坯成型后，滑柱2.3带动湿坯转移模2.1竖直下移到吸滤成型模具1.1上把湿坯吸起，湿坯跟随湿坯转移模向上提升到位，接着左热压下模6.1a 和右热压下模6.2a交替地水平移动到湿坯转移模2.1的正下方，湿坯转移模下移把湿坯移送到左热压下模6.1a (或右热压下模6.2a)上，湿坯转移完成后湿坯转移模上升；左热压下模 (或右热压下模)带着湿坯水平返回到左热压上模6.1b 的正下方(或右热压上模6.2b的正下方)，左热压上模6.1b下行与左热压下模合模（或右热压上模下行与右热压下模合模），对湿坯进行热压干燥定型，制成干燥的制品后被送出或进入下一工序。
图2.1所示的，是含所述湿坯转移装置2的全自动单热压植物纤维模塑成型机，与上述全自动双热压植物纤维模塑成型机相比，全自动单热压植物纤维模塑成型机只含一个热压定型装置，当完成湿坯成型后，采用一个热压定型装置对湿坯进行干燥定型。
图1所示的，是含所述湿坯转移装置2的无热压装置的植物纤维模塑吸滤成型机，这种植物纤维模塑吸滤成型机不含有热压装置，当完成湿坯成型后，滑柱2.3带动湿坯转移模2.1竖直向下移动，把湿坯从吸滤成型模具1.1中吸起后，吸滤成型模具1.1带着湿坯上升，把湿坯移出吸滤成型模具1.1，湿坯经过其它各种方式被移送到下一工序进行处理或被送到烘道中进行加热干燥或被送到其它装置中进行加热干燥。
