弧形底板模具的制作方法
Manufacturing method of arc bottom plate mould
先用木板或1.8厚的密度板做出所需的弧度，规范的弧度比为 1：3.25（仅供参考）
The first board or 1.8 thick density board to make the required radian, the specification of the radian ratio of 1:3.25 (for reference only)
2.用0.9或1公分厚的密度板裁好所需求的尺度，底部两头各放一块做好的弧度（假如密度板做的弧度就把两块弧度钉在一同来添加其强度）。用气钉枪把密度板和弧度钉在一同。中心也多钉几条弧度，其它两边用直条密度板钉上即可。
2 with a density of 0.9 or 1 cm thick board to cut the desired scale, the bottom of each of the two put a good radian (if the density of the board to do the radian of the two nails together to increase their strength). The gas density board and nail gun nail radian together. The center is also more than a few nails, the other two sides with a straight board can be nailed.
3.阴模和原先的做法相同。4、阴阳模具作好后，把阳模四边几四脚用砂纸或锉刀处理以下，使其边角略圆滑些。四角略带些倾斜度，以便脱模。阴模底部用砂纸打磨一下即可。
3 the same as the original method. 4, prepare to die of yin and Yang, male and four feet with sandpaper or file processing below, the corner slightly tactful. The four corners are slightly inclined so as to release. The bottom of the mold can be polished with sandpaper.
4.不管弧形底板模具中心的弧度有多大，尽量确保两边边的高度在3公分左右。太高难起成型后的板材四边还简单裂开。
4 no matter how large the curvature of the arc bottom mold center, try to ensure that the height of both sides of the 3 cm. Too difficult from the plate after forming simple split edges.
5.最终压吸成形。
5 Final suction forming.
怎么防止亚克力制品变形
How to prevent the deformation of acrylic products
安装结构须预留缩短和胀大空隙。须钻椭圆形的螺孔合作螺丝锁定。选用弹性橡胶垫片。热成形可提高抗冲强度，并开释内应力。热成型成波涛型、钻石型和半圆形可防止亚克力板因自重下垂发生变形。运用大幅度亚克力板时，须添加厚度以防板材因为自重而下垂变形。挑选恰当的厚度以防止因风载而致使亚克力板曲折变形。热成型成波涛型、钻石型和半圆形可防止亚克力板因自重下垂发生变形。运用大幅度亚克力板时，须添加厚度以防板材因为自重而下垂变形。挑选恰当的厚度以防止因风载而致使亚克力板曲折变形。
The installation shall be provided with a shortened and enlarged void. To drill the oval screw bolt. Elastic rubber gasket. The hot forming can improve the impact strength and release the internal stress. The heat forming into the wave type, diamond type and semicircle can prevent the acrylic plate deformation due to self weight deformation. The use of large acrylic plate, the thickness must be added in order to prevent the plate due to self weight and sagging deformation. Select the appropriate thickness to prevent the deformation of the acrylic plate due to wind load.
