De reden fan ynfloed op de kwaliteit fan die casting

Tiid: 2020-06-04 Hits: 27

De trochgeande ûntwikkeling fan wittenskip en technology, de easken foar die-casting-produkten wurde heger en heger. Fan 'e feiligens en estetyk hawwe hege easken. De kontrôle fan 'e oerflakstemperatuer fan' e die-casting-mal is heul wichtich foar de produksje fan dielde casting-dielen fan hege kwaliteit. Unjildige as ûnfatsoenlike maltemperatuer sil ek liede ta ynstabiliteit fan 'e casting-standert. Tidens it produksjeproses wurdt it gieten ferfoarme, en ûntsteane defekten lykas termyske druk, skimmesticking, eksterne depresje, ynterne krimpholte en thermyske bubble. As it temperatuerferskil fan 'e mal grut is, hawwe de fariabelen yn' e produksjesyklus, lykas it ynfoljen fan tiid, koeltiid en spuitetiid, ferskillende graden fan ynfloed.

  Some die castings are not formed, and the cavity is not full

  Factors: 1. The temperature of the die-casting mold is too low; 2. The temperature of the molten metal is low; 3. The pressure of the press is too low; 4. The lack of molten metal and the injection speed are too high;

  Adjustment methods: 1. 2. Improve the die casting mold and the temperature of the molten metal; 3. Replace the high pressure die casting machine. 4. Add sufficient liquid metal to reduce the injection speed and increase the thickness of the feed inlet.

   1. The planning of die-casting parts. At the time of planning, extra attention should be paid to making the structure of die-casting parts as simple as possible under the premise of using the request. Otherwise, the shortcomings of die castings such as pits, pores, and cracks are simply presented. The standard requirements for Shenzhen aluminum die-casting are accurate and reasonable. Otherwise, it will cause unnecessary trouble for the planning and management of mold planning and processing. Many unqualified products will be produced.

   2. The structure of the mold, the processing accuracy and the selection of the mold data are also meticulous: aluminum alloy die casting is die-cast by the mold, and the selection of the mold data is also greatly related to the quality of the product. The mold structure is not good enough, and it is difficult to pass the product even if the measures are adopted technically.

3. De reduksje taryf fan casting gegevens: As de reduksje taryf fan casting data wurdt normaal jûn as in unifoarm persintaazje of as in persintaazje mei in beskate feroaring yn skaal, spesjaal omtinken moat wurde bestege oan de timing fan hege presyzje die casting planning mallen , It is nedich om earst in eksperimintele mal te meitsjen. Nei it krijen fan de gegevens oer de eksperimintele mal, plan om foarmen foar in soad produksjes te meitsjen.

   4. Preparation and implementation of technology: The preparation of die-casting technology is determined by the technical level of the operator, the quality of the mold and die-casting equipment. Nowadays, it is difficult for China to control the technical parameters of die-casting under the condition of die-casting equipment, which is stable, reliable and accurate.

Die casting is in diel fan druk casting. It is in meganyske die-casting-masine foar drukgieten foarsjoen fan in casting-mal. It koper, sink, aluminium (aluminiumlegearing) en oare metalen dy't ferwaarme binne ta in floeibere steat wurde yn 'e ynlaat fan' e die-casting-masine getten. Masjine-casting, casting fan koper, sink, aluminium (aluminiumlegaasje) ûnderdielen mei beheinde foarmen en maten fan 'e mal.
