注塑模具在制造过程中会有一些次品或缺陷,我们每一个塑胶模具厂都会非常注重这个问题,下面就一起探讨一下,造成缺陷的原因以及补救方法。
There will be some defective products or defects in the manufacturing process of injection mold. Every plastic mold factory will pay great attention to this problem. Let's discuss the causes and remedies of the defects together.
一、注塑模具造成此缺陷的原因
1、 Reasons for this defect of injection mold
(1)熔融温度不是太高就是太低。
(1) The melting temperature is either too high or too low.
(2)模腔内塑料不足。
(2) Insufficient plastic in the mold cavity.
(3)冷却阶段时接触塑料的面过热。
(3) During the cooling phase, the surface contacting the plastic is overheated.
(4)流道不合理、浇口截面过小。
(4) The runner is unreasonable and the gate section is too small.
(5)模温是否与塑料特性相适应。
(5) Whether the mold temperature is compatible with the plastic characteristics.
(6)产品结构不合理(加强进古过高,过厚,明显厚薄不一)
(6) The product structure is unreasonable (the reinforcement is too high, too thick, and the thickness is obviously different)
(7)冷却效果不好,产品脱模后继续收缩。
(7) The cooling effect is not good, and the product continues to shrink after demoulding.
二、注塑模具缺陷的补救方法
2、 Remedy of injection mold defects
(1)调整射料缸温度。
(1) Adjust the temperature of the injection cylinder.
(2)调整螺杆速度以获得正确的螺杆表面速度。
(2) Adjust the screw speed to obtain the correct screw surface speed.
(3)增加注塑量。
(3) Increase injection quantity.
(4)保证使用正确的垫料;增加螺杆向前时间;增加注塑压力;增加注塑速度。
(4) Ensure the correct padding is used; Increase the screw forward time; Increase injection pressure; Increase injection speed.
(5)检查止流阀是否安装正确,因为非正常运行会引致压力流失。
(5) Check whether the check valve is installed correctly, because abnormal operation will cause pressure loss.
(6)降低模具表面温度。
(6) Reduce the mold surface temperature.
(7)矫正流道避免压力损失过大;根据实际需要,适当扩大截面尺寸。
(7) Correct the flow channel to avoid excessive pressure loss; Appropriately expand the section size according to the actual needs.
(8)根据所用塑料的特性及产品结构适当控制模温。
(8) The mold temperature shall be properly controlled according to the characteristics of the plastic used and the product structure.
(9)在允许的情况下改善产品结构。
(9) Improve the product structure if allowed.
(10)设法让产品有足够的冷却。
(10) Try to make the product cool enough.
