在注塑模具的生產(chǎn)和應(yīng)用過程中，各種情況下經(jīng)常會(huì)出現(xiàn)故障，浪費(fèi)了大量的人力物力，影響了模具加工的生產(chǎn)進(jìn)度和經(jīng)濟(jì)效益。因此，了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(biāo)準(zhǔn)模塊作為模具初加工的基礎(chǔ)，加工分粗加工和精加工兩個(gè)工序完成。為粗加工預(yù)留1.5-2mm，在精加工前通過熱處理消除內(nèi)應(yīng)力，使機(jī)加工內(nèi)應(yīng)力最小化，從而保持模塊的長期尺寸穩(wěn)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(biāo)準(zhǔn)化生產(chǎn)得到廣泛實(shí)施，模架得到廣泛應(yīng)用。進(jìn)廠前，根據(jù)用戶要求對模架進(jìn)行精密定位設(shè)置，導(dǎo)向裝置已精密加工到位。即使加工產(chǎn)生內(nèi)應(yīng)力變形，也不可能采用熱處理工藝消除工件中存在的內(nèi)應(yīng)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(jì)南注塑模具認(rèn)為，為了保證裝配精度的要求，通過機(jī)械加工來修正幾何變形。這個(gè)方案在理論上并不嚴(yán)謹(jǐn)。雖然已經(jīng)糾正了明顯的幾何變形，但導(dǎo)向裝置是由于加工應(yīng)力的作用造成的。位移未校正，金屬內(nèi)應(yīng)力未因幾何形狀的機(jī)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(chǎn)中受到各種不確定因素及其自身原因的影響，模塊加工的殘余內(nèi)應(yīng)力始終釋放，導(dǎo)致動(dòng)、定模變形。隨著動(dòng)、定模模塊的變形，密封面出現(xiàn)不規(guī)則的變化，飛刺的數(shù)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(xiàn)在彈出機(jī)構(gòu)上。頂桿運(yùn)動(dòng)平穩(wěn)，無側(cè)壁摩擦，隨著模塊變形的增加，頂桿的側(cè)壁摩擦逐漸發(fā)生，直至出現(xiàn)熱粘合現(xiàn)象。內(nèi)應(yīng)力釋放過程是模塊二次變形的過程。應(yīng)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(xiàn)代工業(yè)生產(chǎn)中起著極其重要的作用，其質(zhì)量直接決定了產(chǎn)品的質(zhì)量。改進(jìn)注塑模具，提高模具的使用壽命，是一個(gè)亟待解決的問題。更多詳情，請查閱網(wǎng)站
