Cov laj thawj ntawm cuam tshuam qhov zoo ntawm kev tuag casting

Sijhawm: 2020-06-04 Ntaus: 27

Txoj kev loj hlob tsis tu ncua ntawm cov kev tshawb fawb thiab thev naus laus zis, cov tseev kom muaj rau cov khoom lag luam tuag tau txais los ntawm ntau dua thiab siab dua. Los ntawm kev nyab xeeb thiab kev zoo nkauj muaj qhov siab xav tau. Kev tswj ntawm qhov kub ntawm lub ntsej muag tuag-casting pwm yog qhov tseem ceeb heev rau kev tsim cov khoom ua tau zoo-tuag los ua qhov chaw. Cov pwm tsis sib xws los yog pwm tsis zoo yuav ua rau muaj kev tsis zoo ntawm cov txheej txheem casting. Thaum lub sijhawm txheej txheem ntau lawm, cov casting yog deformed, thiab cov tsis xws luag xws li lub siab thermal, pwm lub cev, kev nyuaj siab sab nraud, sab hauv lub ntsej muag ntsws thiab cov kab ua npuas thermal tshwm sim. Thaum cov pwm kub qhov sib txawv yog qhov loj, qhov hloov pauv nyob hauv lub voj voog ntau lawm, xws li sau lub sijhawm, lub sijhawm txias thiab lub sijhawm ntsuas, muaj qhov sib txawv ntawm kev ua.

  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. Qhov txo qis ntawm cov ntaub ntawv pov tseg: Thaum qhov txo qis ntawm cov ntaub ntawv pov tseg feem ntau yog muab raws li feem pua ​​zoo ib yam lossis feem pua ​​nrog qee qhov kev hloov pauv hauv qhov ntsuas, tshwj xeeb yuav tsum them rau lub sijhawm sijhawm ntawm high-precision tuag casting npaj pwm. Cov. Nws yog qhov tsim nyog los ua ib qho kev sim pwm ua ntej. Tom qab tau txais cov ntaub ntawv ntawm cov pwm sim, npaj kev tsim cov pwm rau ntau cov khoom lag luam.

   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.

Tuag casting yog ib feem ntawm siab casting. Nws yog lub siab tuag lub tshuab casting tuag tuag tshuab nruab nrog ib lub tshuab casting. Cov tooj liab, zinc, aluminium (aluminium alloy) thiab lwm cov hlau ua kom sov mus rau lub xeev ua kua yog hliv rau hauv qhov nkag ntawm lub tshuab tuag casting. Tshuab tuag casting, casting tooj liab, zinc, aluminium (aluminium alloy) qhov chaw nrog cov duab txwv thiab ntau thiab tsawg ntawm cov pwm.
