注塑模具試模時(shí)可能會(huì)出現(xiàn)什么問題

來源：http://m.fwdq.net/ 日期：2022-08-23

濟(jì)南注塑模具工廠在正式生產(chǎn)產(chǎn)品之前都要進(jìn)行模具試模的步驟

，在試模的過程中

，往往會(huì)碰到這樣那樣的問題

，這次總結(jié)了幾個(gè)常見的問題以及解決辦法。

Jinan injection mold factory always carries out mold test before formally producing products. In the process of mold test, we often encounter such problems. This time, we summarize several common problems and solutions.

一

、主澆道粘模

、 Main runner die sticking

1、拋光主澆道→2

、噴嘴與模具中心重合→3

、降低模具溫度→4、縮短注射時(shí)間→5

、增加冷卻時(shí)間→6、檢查噴嘴加熱圈→7

、拋光模具表面→8

、檢查材料是否污染。

1. Polishing the main runner → 2. The nozzle coincides with the mold center → 3. Reduce the mold temperature → 4. Shorten the injection time → 5. Increase the cooling time → 6. Check the nozzle heating ring → 7. Polish the mold surface → 8. Check whether the material is polluted.

二

、塑件脫模困難

、 Difficult to demould plastic parts

1、降低注射壓力→2

、縮短注射時(shí)間→3

、增加冷卻時(shí)間→4、降低模具溫度→5

、拋光模具表面→6

、增大脫模斜度→7、減小鑲塊處間隙

1. Reduce the injection pressure → 2. Shorten the injection time → 3. Increase the cooling time → 4. Reduce the mold temperature → 5. Polish the mold surface → 6. Increase the demoulding slope → 7. Reduce the gap at the insert

三

、尺寸穩(wěn)定性差

、 Poor dimensional stability

、改變料筒溫度→2、增加注射時(shí)間→3

、增大注射壓力→4

、改變螺桿背壓→5、升高模具溫度→6

、降低模具溫度→7

、調(diào)節(jié)供料量→8、減小回料比例

1. Change the barrel temperature → 2. Increase the injection time → 3. Increase the injection pressure → 4. Change the screw back pressure → 5. Increase the mold temperature → 6. Reduce the mold temperature → 7. Adjust the feed amount → 8. Reduce the return ratio

四

、表面波紋

、 Surface ripple

1、調(diào)節(jié)供料量→2

、升高模具溫度→3

、增加注射時(shí)間→4、增大注射壓力→5

、提高物料溫度→6

、增大注射速度→7、增加澆道與澆口的尺寸

1. Adjust the feeding amount → 2. Increase the mold temperature → 3. Increase the injection time → 4. Increase the injection pressure → 5. Increase the material temperature → 6. Increase the injection speed → 7. Increase the size of the sprue and gate

五

、塑件翹曲和變形

、 Warpage and deformation of plastic parts

1、降低模具→2

、降低物料溫度→3

、增加冷卻時(shí)間→4、降低注射速度→5

、降低注射壓力→6

、增加螺桿背壓→7、縮短注射時(shí)間

1. Lower the mold → 2. Lower the material temperature → 3. Increase the cooling time → 4. Lower the injection speed → 5. Lower the injection pressure → 6. Increase the screw back pressure → 7. Shorten the injection time

六

、塑件脫皮分層

、 Peeling and delamination of plastic parts

1、檢查塑料種類和級(jí)別→2

、檢查材料是否污染→3

、升高模具溫度→4、物料干燥處理→5

、提高物料溫度→6

、降低注射速度→7、縮短澆口長度→8

、減小注射壓力→9

、改變澆口位置→10、采用大孔噴嘴。

1. Check the type and grade of plastic → 2. Check whether the material is polluted → 3. Raise the mold temperature → 4. Dry the material → 5. Raise the material temperature → 6. Reduce the injection speed → 7. Shorten the gate length → 8. Reduce the injection pressure → 9. Change the gate position → 10. Use large hole nozzle.
