塑胶模具设计需求留意什麼
What should we pay attention to in the design of plastic moulds
1、进胶口应开设在产物肉厚局部,保证充模别扭和完全;
1. The rubber inlet should be set on the part of the product thickness to ensure that the filling is awkward and complete.
2、虽然开设在不影响产物表面和功能处,可在边缘或底部处;
2. Although it is provided on the surface and function of the product, it can be located at the edge or the bottom.
3、在浇口临近之冷料穴,尽端常配置拉料杆,以利于浇道脱模;
3. In the cold material hole near the gate, pull rods are often arranged at the end to facilitate the demoulding of the gate.
4、大型或扁平产物,提议选用多点进浇,可预防产物翘曲变形和缺料;
4. For large or flat products, multi-point pouring is proposed to prevent warpage and material shortage.

5、其地位应选在使塑料充模流程对照弱点,以增加压力盈余,有利于模具排气;
5. Its position should be to make the filling process of plastics compare with the weakness, so as to increase the pressure surplus, which is conducive to the exhaust of the mould.
6、在细长型芯临近预防开设浇口,以免料流间接冲锋型芯,发作变形错位或弯曲;
6. Gate should be set up in the vicinity of slender core to prevent material flow indirectly charging the core, causing deformation dislocation or bending.
7、浇口尺寸由产物大小,几何方式,构造和塑料种类决策,可先取小尺寸再依据试模状况停止更正;
7. Gate size is determined by product size, geometry, structure and plastics type. Small size can be taken first, and then the correction can be stopped according to the test condition.
8、可经过模流剖析或经历,推断产物因浇口地位而发作之交融线处,能否影响产物表面和功能,可加设冷料穴加以处置;
8. It can be inferred from the flow analysis or experience that the intersection line where the product occurs due to the gate position can affect the surface and function of the product, and can be disposed of by adding cold material caves.
9、一模多穴时,相反的产物选用对称进浇办法,关于差别产物在异样模具中成型时,优先将对照大产物放在接近主流道的地位。
9. When one mold is multi hole, the opposite product adopts symmetrical casting method. When the differential products are molded in different moulds, the control products will be placed near the mainstream.
