大型注塑模具的壽命會受到一些因素的影響，為了能夠延長大型注塑模具的壽命，大型注塑模具的操作工們應該對影響其壽命的因素有所了解，從大型注塑模具失效的普遍現象分析，大型注塑模具失效可分為自然失效（包括過量變形、表面損傷和冷熱疲勞等）、人為損壞和異常破壞三種形式。

Large injection mold life will be affected by some factors, in order to prolong the service life of large injection mold, large injection mold operator who should have an understanding of the factors affecting the life of the common phenomenon, analysis of failure from a large injection mold, large injection mould failure can be divided into natural failure (including excessive deformation, surface damage and cold and hot fatigue etc.), three kinds of man-made damage and abnormal damage.

自然失效：主要包括型腔的剛性不足導致的過量變形，如：推出機構卡滯，成型面、成型尺寸磨損，細長桿件疲勞折斷，定位導向件、滑動件、分型面等剛性接觸磨損和燒傷、冷熱疲勞等。

Failure: including excessive deformation, insufficient rigidity of cavity causes such as: launch mechanism card, forming surface, forming size wear, slender rod fatigue fracture, positioning guide, slider, parting surface of rigid contact wear and thermal fatigue, burn etc..

人為損壞：人為損壞是縮短模具壽命的另一個重要因素，我們常常看到一副模具只生產幾萬模次就已經傷痕累累，究其原因均為操作不慎壓塌、碰傷等等非正常損壞造成的。尤其是對于有鑲嵌件放置要求的模具，因操作人員把鑲嵌件誤放（漏裝、多裝、方向錯裝）引起事故，損壞模具的情況時有發生。

The damage: damage is another important factor to shorten the die life, we often see a pair of mold production only tens of thousands of times die had been scarred, the reason for careless operation, collapse and so on non normal damage caused by collision. Especially for the requirements of the mold inserts placed, because the operator to insert misload (missing, loaded, wrong direction loading) of accidents caused by damage to the mold, the situation has occurred.

異常破壞：異常破壞是指模具因材料內部缺陷和熱處理不當產生的一些不易事先被發現的隱患引起的。一般正確選材和良好的熱處理工藝就可以加以控制，故在生產中異常破壞較為少見。

Abnormal destruction: abnormal damage refers to the mold due to the internal defects of the material and improper heat treatment of some of the hidden trouble is not easy to find. In general, the correct material selection and good heat treatment process can be controlled.
