使用山东快速成型方法制作硅橡胶模具时的注意事项你知道包含什么内容吗？我们从几个方面来讲解下问题，如下：

Do you know what should be paid attention to when using Shandong rapid prototyping method to make silicone rubber mold? We will explain the following problems from several aspects:

（1）起模操作要小心。对于原型中有起模斜度（拔模斜度）、凹模和凸起等结构的情况，脱模时只要不超出硅橡胶抗撕裂强度范围内的变形，一般都能顺利起模，但起模时要非常小心，避免损坏硅橡胶模具和制作。

(1) Be careful in mold lifting operation. For the prototype with mold lifting angle (draft angle), concave and convex structures, as long as the deformation does not exceed the silicone rubber tear resistance range during demoulding, the mold can generally be lifted smoothly, but the mold should be lifted very carefully to avoid damaging the silicone rubber mold and production.

（2）原型零件应满足一定的性能要求。原型要有较好的刚性和一定的强度，以免在制模时变形。并且，原型须有正确的形状、精度的尺寸和较高的光洁度。

(2) Prototype parts shall meet certain performance requirements. The prototype shall have good rigidity and certain strength to avoid deformation during mold making. In addition, the prototype must have correct shape, accurate size and high finish.

（3）选择合理的浇注方式。浇注过程中，如果浇注的方法和浇注位置不当，会使型腔内的气泡裹入型腔内，使模具在固化后留下缺陷。解决的办法就是浇注过程中要分批逐渐地浇注，即先在原型表面薄薄地浇注一层，待表层硅橡胶半固化状态后，再浇注余下的材料，使硅橡胶和原型能够充分接触而事气泡能比较容易地排出。

(3) Select a reasonable pouring method. In the pouring process, if the pouring method and pouring position are improper, the bubbles in the mold cavity will be wrapped into the mold cavity, leaving defects after the mold is cured. The solution is to pour gradually in batches during the pouring process, that is, first pour a thin layer on the surface of the prototype, and then pour the remaining materials after the surface layer of silicone rubber is in the semi curing state, so that the silicone rubber and the prototype can fully contact and the bubbles can be easily discharged.

（4）模具须放置平整。浇注硅橡胶模具时应尽量使硅橡胶模具上、下底面平整，避免端面凹凸不平。否则，在利用硅橡胶模浇注零件时，由于模具放置不平，容易引起浇注制件的尺寸变形。

(4) The mold must be placed flat. When pouring the silicone rubber mold, the upper and lower bottom surfaces of the silicone rubber mold shall be flat as far as possible to avoid uneven end surfaces. Otherwise, when the silicon rubber mold is used for pouring parts, the uneven placement of the mold will easily cause dimensional deformation of the pouring parts.

（5）无论用常压、加压或减压法制造硅橡胶模，模具内都可能混有气泡。气泡能造成模具的缺陷，在以模具浇注制件时可能有缩孔，有时也可能会有凸出点，影响制件的质量，并使橡胶模由于应力几种而强度降低，造成破损。

(5) Whether the silicone rubber mold is made by normal pressure, pressurization or decompression, bubbles may be mixed in the mold. Bubbles can cause defects in the mold. There may be shrinkage holes or bulges when casting parts with the mold, affecting the quality of the parts, and reducing the strength of the rubber mold due to several stresses, causing damage.
