山东铝合金压铸厂家如何解决错型和麻面问题?

山东铝合金压铸厂家在官网为您提供解决办法,今天主要讲解的是错型和麻面问题。
Shandong Aluminum alloy die casting manufacturers in the official website to provide you with solutions, today's main explanation is the wrong type and pockmarked problem.
错型主要包括错位、错边、错缝和错扣四种情况,它的主要表现是压铸件在分型面上出现错位,发生相对位移,也就是对螺纹称错扣。铝合金压铸厂家探究其中的原因,将其归纳为三点:加工中使用的beplay全站app安卓出现镶块位移;beplay全站app安卓的导向件出现磨损;两半模的镶块出现制造误差;为避免出现错型,厂家需及时调整或修整镶块,进行紧固并消除误差,还有及时更换导柱导套。
There are four types of malocclusion: dislocation, misalignment, stagger seam and stagger thread. The main performance of malocclusion is the relative displacement of the die casting on the parting surface, that is, the malocclusion of the thread. Aluminum alloy die-casting manufacturers explore the reasons, which can be summarized into three points: the displacement of the insert used in processing; the wear of the guide part of the die; the manufacturing error of the insert of the two half dies; in order to avoid the wrong type, the manufacturer needs to adjust or repair the insert in time, fasten and eliminate the error, and replace the guide post and guide sleeve in time.

麻面也是铝合金铸件生产中会出现的质量问题,它又被称为麻点,是在充型过程中,因为beplay全站app安卓温度或合金液温度过低,导致的在类似欠压条件下在铸件表面形成的细小麻点状分布区域。出现麻面的原因可能是内浇口厚度偏小,或者是铝合金压铸厂家填充时金属分散成密集液滴,高速撞击型壁。相应的解决办法就是适当调整内浇口的厚度,或者是生产前正确设计浇注系统,尽量避免金属液喷溅,改善排气条件,避免金属液卷入过多气体,也要降低内浇口速度,提高beplay全站app安卓温度。
Pockmarked surface is also a quality problem in the production of aluminum alloy castings. It is also called pockmarked surface. It is a small pockmarked distribution area formed on the surface of castings under similar under pressure conditions due to too low mold temperature or alloy liquid temperature during mold filling. The reason of pitted surface may be that the thickness of inner gate is too small, or the metal is dispersed into dense droplets when filling by aluminum alloy die casting factory, which impacts the mold wall at high speed. The corresponding solution is to adjust the thickness of the inner gate properly, or design the gating system correctly before production, try to avoid the splashing of liquid metal, improve the exhaust conditions, avoid the liquid metal involved in too much gas, reduce the speed of the inner gate, and increase the mold temperature.
