Y rheswm dros effeithio ar ansawdd castio marw

Amser: 2020-06-04 Trawiadau: 27

Mae datblygiad parhaus gwyddoniaeth a thechnoleg, y gofynion ar gyfer cynhyrchion castio marw yn mynd yn uwch ac yn uwch. O'r diogelwch ac estheteg mae gofynion uchel. Mae rheoli tymheredd arwyneb y mowld castio marw yn bwysig iawn ar gyfer cynhyrchu rhannau castio marw o ansawdd uchel. Bydd tymheredd llwydni anwastad neu amhriodol hefyd yn arwain at ansefydlogrwydd y safon castio. Yn ystod y broses gynhyrchu, mae'r castio yn cael ei ddadffurfio, ac mae diffygion fel pwysau thermol, glynu llwydni, iselder allanol, ceudod crebachu mewnol a swigen thermol yn digwydd. Pan fydd gwahaniaeth tymheredd y mowld yn fawr, mae gan y newidynnau yn y cylch cynhyrchu, fel amser llenwi, amser oeri ac amser chwistrellu, wahanol raddau o ddylanwad.

  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. Cyfradd ostwng data castio: Pan roddir cyfradd ostwng data castio fel canran unffurf neu fel canran gyda newid penodol mewn graddfa, dylid rhoi sylw arbennig i amseriad mowldiau cynllunio castio marw manwl uchel . Mae angen gwneud mowld arbrofol yn gyntaf. Ar ôl cael y data ar y mowld arbrofol, cynlluniwch gynhyrchu mowldiau ar gyfer llawer o gynyrchiadau.

   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.

Mae castio marw yn rhan o gastio pwysau. Mae'n beiriant castio marw mecanyddol castio pwysau gyda mowld castio. Mae'r copr, sinc, alwminiwm (aloi alwminiwm) a metelau eraill sy'n cael eu cynhesu i gyflwr hylifol yn cael eu tywallt i fewnfa'r peiriant castio marw. Castio marw peiriant, castio rhannau copr, sinc, alwminiwm (aloi alwminiwm) gyda siapiau a meintiau cyfyngedig y mowld.
