不同情況下注塑模具的失效處理流程

在注塑模具的生產和應用過程中│₪•·,各種情況下經常會出現故障│₪•·,浪費了大量的人力物力│₪•·,影響了模具加工的生產進度和經濟效益╃☁·。因此│₪•·,瞭解注塑模具在不同情況下的失效處理過程非常重要╃☁·。
In the process of injection molding, a lot of manpower and economic benefits are often wasted. Therefore, it is very important to understand the failure treatment process of injection mold under different conditions.
以標準模組作為模具初加工的基礎│₪•·,加工分粗加工和精加工兩個工序完成╃☁·。為粗加工預留1.5-2mm│₪•·,在精加工前透過熱處理消除內應力│₪•·,使機加工內應力最小化│₪•·,從而保持模組的長期尺寸穩定性╃☁·。
Taking the standard module as the basis of die preliminary machining, the machining is divided into two processes: rough machining and finish machining. Reserve 1.5-2mm for rough machining, and eliminate the internal stress through heat treatment before finishing, so as to minimize the internal stress of machining, so as to maintain the long-term dimensional stability of the module.
模具標準化生產得到廣泛實施│₪•·,模架得到廣泛應用╃☁·。進廠前│₪•·,根據使用者要求對模架進行精密定位設定│₪•·,導向裝置已精密加工到位╃☁·。即使加工產生內應力變形│₪•·,也不可能採用熱處理工藝消除工件中存在的內應力╃☁·。
Die standardized production has been widely implemented, and die base has been widely used. Before entering the factory, the mold base is precisely positioned and set according to the user's requirements, and the guide device has been precisely machined in place. Even if the processing produces internal stress deformation, it is impossible to eliminate the internal stress in the workpiece by heat treatment process.

濟南注塑模具認為│₪•·,為了保證裝配精度的要求│₪•·,透過機械加工來修正幾何變形╃☁·。這個方案在理論上並不嚴謹╃☁·。雖然已經糾正了明顯的幾何變形│₪•·,但導向裝置是由於加工應力的作用造成的╃☁·。位移未校正│₪•·,金屬內應力未因幾何形狀的機械校正而消失╃☁·。
Jinan injection mold believes that in order to ensure the requirements of assembly accuracy, the geometric deformation is corrected by machining. This scheme is not rigorous in theory. Although the obvious geometric deformation has been corrected, the guide device is caused by the action of machining stress. The displacement is not corrected, and the internal stress of the metal does not disappear due to the mechanical correction of the geometry.
模具在生產中受到各種不確定因素及其自身原因的影響│₪•·,模組加工的殘餘內應力始終釋放│₪•·,導致動·₪▩₪│、定模變形╃☁·。隨著動·₪▩₪│、定模模組的變形│₪•·,密封面出現不規則的變化│₪•·,飛刺的數量逐漸增加╃☁·。
The mold is affected by various uncertain factors and their own reasons in production. The residual internal stress of module processing is always released, resulting in the deformation of moving and fixed mold. With the deformation of the moving and fixed mold modules, the sealing surface changes irregularly, and the number of flying thorns increases gradually.
另一方面│₪•·,它出現在彈出機構上╃☁·。頂杆運動平穩│₪•·,無側壁摩擦│₪•·,隨著模組變形的增加│₪•·,頂杆的側壁摩擦逐漸發生│₪•·,直至出現熱粘合現象╃☁·。內應力釋放過程是模組二次變形的過程╃☁·。應力因子越大│₪•·,脫模越快│₪•·,模具失效越快╃☁·。
On the other hand, it appears on the ejection mechanism. The ejector rod moves smoothly without side wall friction. With the increase of module deformation, the side wall friction of the ejector rod gradually occurs until thermal bonding occurs. The internal stress release process is the process of secondary deformation of the module. The greater the stress factor, the faster the demoulding and the faster the die failure.
注塑模具在現代工業生產中起著極其重要的作用│₪•·,其質量直接決定了產品的質量╃☁·。改進注塑模具│₪•·,提高模具的使用壽命│₪•·,是一個亟待解決的問題╃☁·。更多詳情│₪•·,請查閱網站www.voyagesvietnamcambodge.com╃☁·。
Injection mold plays an extremely important role in modern industrial production, and its quality directly determines the quality of products. Improving the injection mold and improving the service life of the mold is an urgent problem to be solved. For more details, please refer to the website www.voyagesvietnamcambodge.com com╃☁·。
