塑膠模具爆裂是注塑件加工廠家比較經(jīng)常發(fā)生的一個(gè)質(zhì)量問(wèn)題，這個(gè)性質(zhì)是非常嚴(yán)重，那主要是怎么形成的呢？
Plastic mold burst is a quality problem that often occurs in injection molding manufacturers. This property is very serious. How is it mainly formed?
輕按一下就有爆裂的這種情況。該位置主要是粘合線(xiàn)，即注塑模具加工廠在設(shè)計(jì)膠合點(diǎn)時(shí)未將其設(shè)計(jì)在適當(dāng)?shù)奈恢?，而是在焊縫的頂部形成了凸點(diǎn)。這也取決于外面較薄的位置。特別是在ABS材料的生產(chǎn)中，很容易折斷。經(jīng)驗(yàn)豐富的設(shè)計(jì)工程師將首先檢查膠水入口點(diǎn)，然后將注塑模具焊縫驅(qū)動(dòng)到不會(huì)破裂的位置。
There is a burst at the touch of a button. This position is mainly the bonding line, that is, the injection mold processing plant did not design the bonding point in the appropriate position, but formed a convex point on the top of the weld. It also depends on the thinner location outside. Especially in the production of ABS materials, it is easy to break. Experienced design engineers will first check the glue entry point and then drive the injection mold weld to a position where it will not crack.
注塑加工廠的注塑人員離職超過(guò)20分鐘。當(dāng)他們重新就崗時(shí)，他們沒(méi)有將掉在桶里太久的廢膠扔掉，并導(dǎo)致橡膠變質(zhì)。如果直接生產(chǎn)，也會(huì)引起爆裂。在這種情況下，更難以分析質(zhì)量。
The injection molding personnel in the injection molding processing plant left their jobs for more than 20 minutes. When they returned to their posts, they did not throw away the waste rubber that had fallen in the bucket for too long, which led to the deterioration of the rubber. If it is produced directly, it will also cause burst. In this case, it is more difficult to analyze the quality.
注塑模具原料有太多的塑料揮發(fā)物，太多的濕度，太多的雜質(zhì)，太多的回收材料以及受污染的注塑模具也可能會(huì)破裂。解決方案：1.清潔噴嘴，防止流向，并且澆口可能被阻塞；2.嚴(yán)格按照噴嘴材料的比例添加；3.將焊縫驅(qū)動(dòng)到不會(huì)破裂的位置；4。暫停中間，暫停后，清除先前的廢料，然后生產(chǎn)新的注塑模具。5.篩分廢料，雜質(zhì)等。
Injection mold raw materials have too many plastic volatiles, too much humidity, too many impurities, too many recycled materials and contaminated injection molds may also break. Solution: 1 Clean the nozzle to prevent flow direction, and the gate may be blocked; 2. Add in strict accordance with the proportion of nozzle material; 3. Drive the weld to a position where it will not crack; 4。 Pause in the middle, after the pause, remove the previous waste, and then produce a new injection mold. 5. Screen waste, impurities, etc.
山東模具制造廠家認(rèn)為加工時(shí)的注意事項(xiàng)要知道，比如在模具方面，精密模具加工設(shè)備的微注塑成型遠(yuǎn)高于傳統(tǒng)的注塑模具成型：在模具加工中，注塑模具加工一般有兩種趨勢(shì)：一是采用鏡面火花加工，以保證高精度模具加工。
Shandong mold manufacturers believe that the precautions in processing should be known. For example, in terms of molds, the micro injection molding of precision mold processing equipment is much higher than the traditional injection mold molding: in mold processing, there are generally two trends in injection mold processing: one is to adopt mirror flame processing to ensure high-precision mold processing.
為了精度，電火花加工應(yīng)使用石墨電極，因?yàn)槭姌O的損耗遠(yuǎn)小于一般銅電極。與普通加工方法相比，另一種替代方法是使用電涂抹，選擇電成型技術(shù)以確保非常高的精度，但缺點(diǎn)是加工周期長(zhǎng)，每個(gè)點(diǎn)都需要注塑成型，并且損傷較小生產(chǎn)，無(wú)法糾正，只能更換損壞的模具。
In order to improve the accuracy, graphite electrode should be used in EDM, because the loss of graphite electrode is much less than that of general copper electrode. Compared with ordinary processing methods, another alternative method is to use electric coating and select electric forming technology to ensure very high accuracy, but the disadvantage is that the processing cycle is long, each point needs injection molding, and the damage is small, which can not be corrected. Only the damaged mold can be replaced.
注塑成型時(shí)，可提前模具溫度（可超過(guò)所用塑料的熔點(diǎn)），使熔體快速完成型腔，避免充模過(guò)程中溫度下降。填充太快且不完整；取出時(shí)，模具溫度會(huì)下降，保持略低于塑料熱變形溫度，然后開(kāi)頂。另外，由于微注塑的質(zhì)量是千年材料產(chǎn)品。只要少于10%的材料被注入到注塑產(chǎn)品中，有很多鑄造系統(tǒng)，因此可以選擇一個(gè)注塑模具來(lái)使用該鑄造系統(tǒng)。
During injection molding, the mold temperature can be advanced (which can exceed the melting point of the plastic used), so that the melt can quickly complete the mold cavity and avoid the temperature drop during mold filling. Filling too fast and incomplete; When taking out, the mold temperature will drop, keep it slightly lower than the plastic thermal deformation temperature, and then open the top. In addition, because the quality of micro injection molding is Millennium material products. As long as less than 10% of the material is injected into the injection molded products, there are many casting systems, so you can choose an injection mold to use the casting system.
塑膠模具加工生產(chǎn)時(shí)出現(xiàn)爆裂的原因便是以上講解了，所以為了注塑模具的質(zhì)量問(wèn)題以及人員的安全，加工期間還是要多注意事項(xiàng)，更多內(nèi)容可以來(lái)網(wǎng)站
