模具投影面積怎麼計算?
壓鑄模具投影面積和壓鑄機噸位怎麼計算?
安全係數取小了,這麼大噸位一般取1.5。因為材料越大,不均勻性越大。罰射比壓需求就越大。2000噸左右的壓力機計算都得取1.5
如何算模具型腔的投影面積?
我有一個笨方法,將型腔的外形投影到分模面,然後用Analysin--Area using Curves ,選擇投影曲線就成了。
塑膠模具怎樣計算噸位
計算鎖模噸位?
1、確定注塑量------假設零件理論重量80g。計算產品螺桿炮筒最大注塑量選型範圍 80/0.75=107g 到 80/0.25=320g 之間。選擇注塑機螺桿炮筒大小的範圍在107~320之間。
2、確定鎖模噸位-------計算鎖模噸位 = (產品正投影面積(cm)*啤數+流道面積)* 材料黏度係數
材料黏度係數:一般PP 0.3~0.4 PA\PC\POM 0.65~0.75。你可以在網上查詢
3、根據模架大小確定鎖模機構尺寸。
計算模具的重量?
在UG中
編輯菜單中的特徵項設置實體密度然後測量體
無數模時,7.85乘以尺寸。
電影高手進,這個問題很難
blowing in the wind
歌手:Bob Dylan
How many roads must a man walk down
Before they call him a man
How many seas must a white dove sail
Before she sleeps in the sand
How many times must the cannon balls fly
Before they're forever banned
The answer, my friend, is blowing in the wind
The answer is blowing in the wind
How many years must a mountain exist
Before it is washed to the sea
How many years can some people exist
Before they're allowed to be free
How many times can a man turn his head
And pretend that he just doesn't see
The answer, my friend, is blowing in the wind
The answer is blowing in the wind
How many times must a man look up
Before he can see the sky
How many ears must one m弗n have
Before he can hear people cry
How many deaths will it take
'Till he knows that too many people have died
The answer, my friend, is blowing in the wind
The answer is blowing in the wind
打勾吧,呵呵.
如何根據產品計算注塑機鎖模力
鎖模力F>=k*P*A
F=實際合模力(千牛)1KG=9.8N
P=模腔平均壓力( Mpa)1MPa=9.8KG
A=製品在分型面上的投影面積(立方厘米)
K=安全係數,一般取1.1-1.6。
射壓射壓=1.5*模內壓力
等級模內壓力(kg/cm2)
精密品550-700
普通品350-500
劣品250-300
注射模澆注系統在分型面上的投影面積如何計算?
需看具體投影形狀複雜程度。有的很有幾何形狀,如:矩形,圓,按照面積計算公式得出。
有的是組合成的形狀,精度要求不高時可以估算得出。
如果需要投影面積精準的話,推薦使用設計軟件,先把澆注系統的形狀投影到分型面上,得到形狀,然後進行面積測量。
