使用山東快速成型方法制作硅橡膠模具時的注意事項你知道包含什么內(nèi)容嗎？我們從幾個方面來講解下問題，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。對于原型中有起模斜度（拔模斜度）、凹模和凸起等結(jié)構(gòu)的情況，脫模時只要不超出硅橡膠抗撕裂強(qiáng)度范圍內(nèi)的變形，一般都能順利起模，但起模時要非常小心，避免損壞硅橡膠模具和制作。

(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）原型零件應(yīng)滿足一定的性能要求。原型要有較好的剛性和一定的強(qiáng)度，以免在制模時變形。并且，原型須有正確的形狀、精度的尺寸和較高的光潔度。

(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）選擇合理的澆注方式。澆注過程中，如果澆注的方法和澆注位置不當(dāng)，會使型腔內(nèi)的氣泡裹入型腔內(nèi)，使模具在固化后留下缺陷。解決的辦法就是澆注過程中要分批逐漸地澆注，即先在原型表面薄薄地澆注一層，待表層硅橡膠半固化狀態(tài)后，再澆注余下的材料，使硅橡膠和原型能夠充分接觸而事氣泡能比較容易地排出。

(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）模具須放置平整。澆注硅橡膠模具時應(yīng)盡量使硅橡膠模具上、下底面平整，避免端面凹凸不平。否則，在利用硅橡膠模澆注零件時，由于模具放置不平，容易引起澆注制件的尺寸變形。

(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）無論用常壓、加壓或減壓法制造硅橡膠模，模具內(nèi)都可能混有氣泡。氣泡能造成模具的缺陷，在以模具澆注制件時可能有縮孔，有時也可能會有凸出點(diǎn)，影響制件的質(zhì)量，并使橡膠模由于應(yīng)力幾種而強(qiáng)度降低，造成破損。

(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.
