在注塑模具的生产和应用过程中，各种情况下经常会出现故障，浪费了大量的人力物力，影响了模具加工的生产进度和经济效益。因此，了解注塑模具在不同情况下的失效处理过程非常重要。

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.

以标准模块作为模具初加工的基础，加工分粗加工和精加工两个工序完成。为粗加工预留1.5-2mm，在精加工前通过热处理内应力，使机加工内应力小化，从而保持模块的长期尺寸稳定性。

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.

模具标准化生产得到广泛实施，模架得到广泛应用。进厂前，根据用户要求对模架进行精密定位设置，导向装置已精密加工到位。即使加工产生内应力变形，也不可能采用热处理工艺工件中存在的内应力。

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.

济南注塑模具认为，为了保证装配精度的要求，通过机械加工来修正几何变形。这个方案在理论上并不严谨。虽然已经纠正了明显的几何变形，但导向装置是由于加工应力的作用造成的。位移未校正，金属内应力未因几何形状的机械校正而消失。

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.

模具在生产中受到各种不确定因素及其自身原因的影响，模块加工的残余内应力始终释放，导致动、定模变形。随着动、定模模块的变形，密封面出现不规则的变化，飞刺的数量逐渐增加。

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，它出现在弹出机构上。顶杆运动平稳，无侧壁摩擦，随着模块变形的增加，顶杆的侧壁摩擦逐渐发生，直出现热粘合现象。内应力释放过程是模块二次变形的过程。应力因子越大，脱模越快，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.
