Side formwork of wheel casting die

一种车轮铸造模具边模

Abstract

The utility model provides a side formwork of wheel casting die, side forms set up to the components of a whole that can function independently includes go up side forms (2), well side forms (3), lower side forms (4) triplex, three passes through bolt -up, its characterized in that: rim department including upward side forms (2) are arranged, face length 20 40mm, surface accuracy ra&lt, 1.6, do it set up 4 to go up side forms (2) 8 stack pipe (21), claw wind (22), claw wind (22) wind pitch -row die cavity face 10 15mm, well side forms (3) face length 20 40mm, surface accuracy ra&lt, 1.6, is thickness for falling the graded distribution, by going last 40 the 60mm gradual change, lower side forms (4) face length 20 40mm, surface accuracy ra&lt, 1.6 arrange 1 to the bcad seats 3 stack pipe (21), claw wind (22), claw wind (22) wind pitch -row die cavity face 10 12mm. The utility model discloses can realize the quick cooling of inside and outside rim, guarantee the regional smooth and easy aluminium liquid feeding passageway of rim, found by the good directional solidification temperature gradient of interior rim to foreign steamer reason.
一种车轮铸造模具边模,边模设置为分体,包括上边模(2)、中边模(3)、下边模(4)三部分,三者通过螺栓紧固,其特征在于:上边模(2)布置在内轮缘处,面长20‑40mm,表面精度Ra<1.6,上边模(2)设置4‑8组套管(21)、爪风(22),爪风(22)风孔距型腔面10‑15mm;中边模(3)面长20‑40mm,表面精度Ra<1.6,厚度为倒梯度分布,由下到上40‑60mm渐变;下边模(4)面长20‑40mm,表面精度Ra<1.6;对胎圈座布置1‑3组套管(21)、爪风(22),爪风(22)风孔距型腔面10‑12mm。本实用新型可以实现内、外轮缘的快速冷却,保证轮辋区域顺畅的铝液补缩通道,构建由内轮缘至外轮缘良好的顺序凝固温度梯度。
