Description

带有冷却装置的轮毂模具 Wheel hub with a mold cooling device

技术领域 FIELD

[0001] 本发明涉及机械铸造技术领域,具体讲是一种带有冷却装置的轮毂模具。 [0001] The present invention relates to the field of foundry technology machinery, specifically a hub mold with cooling system means.

背景技术 Background technique

[0002] 轮毂作为汽车最重要的运动部件之一,对其的性能,重量,使用寿命都有很高的要求。 [0002] As the hub of the most important moving parts of the vehicle, its performance, weight, life of very high demand. 目前,铝合金轮毂以其质量轻、散热快、减震性能好、寿命长、平衡好等优点,在汽车工业中脱颖而出。 Currently, light alloy wheels for its quality, fast heat, shock absorption performance, long life, good balance, etc., come to the fore in the automotive industry.

[0003] 铝合金轮毂一般采用铸造的方式进行生产,用于铸造轮毂的模具主要包括上模具、下模具、侧模具和底座,所述上模具、下模具和侧模具组合后,形成待铸造轮毂的铸造型腔,所述的下模具和侧模具均固定在底座上。 [0003] The aluminum alloy wheel generally used castings of the production, for casting wheel mold including a mold, a lower mold and a side mold assembly upper mold, the lower mold, side mold, and a base, the rear, is formed to be cast hub casting cavity, said side mold and the lower mold are fixed to the base. 浇注时,从位于下模具上的浇注口进料对型腔进行填充,在浇注后的凝固过程中,上模具、下模具和侧模具的交界处所形成的区域是铸造轮毂的热节点,就轮毂的结构而言,上述热节点是指轮辐与轮辋之间的交接过渡部位,由于轮毂一般为圆形,该过渡部位也就为圆环,即整个环形的过渡部位均为热节点,该部位的壁厚较厚,浇注后冷却速度较慢,而与其相邻的轮辐和轮辋的壁厚则相对较薄,冷却速度较快,所以在该处的轮毂铸件毛坯上易产生缩孔、疏松等缺陷,影响轮毂铸件毛坯质量;同时,轮辐中心位置一般也为厚大区,该位置铸件体积最大,冷却十分不易,但是对于铝合金轮毂,冷却越快轮毂强度越好,而且,轮毂冷却需要顺序凝固,所述的顺序凝固是指,铸件的凝固是自表面向中心进行,自远离浇注口部分最先凝固,然后是靠近浇注口部 When pouring, the spout in the mold fed to the cavity is filled from the bottom located during solidification after casting in the mold, the area at the junction of the premises lower die and the side of a mold is thermally node cast hub, on the hub For configuration, the heat transfer node is a transition region between the spokes and the rim, due to the generally circular hub, which is also annular transition portion, i.e. the entire annular portion of the transition nodes are hot, the portion of the thicker wall, the slower the cooling rate after casting, and adjacent spokes and the rim of the wall thickness is relatively thin, the cooling speed, so easy to produce shrinkage, porosity and other defects in the casting blank thereat hub Effects hub rough casting mass; the same time, the spoke center position is also typically Heavy region, the position of casting the largest volume, cooling is very difficult, but for alloy wheels, a cooling wheel strength sooner wheel as possible, and that the hub cooling needs solidification , refers to the solidification, the casting is solidified from the surface to the center, away from the pouring port portion first solidified, then close the spout portion 凝固,最后是浇注口本身凝固,顺序凝固可以使后凝固部位对先凝固部位进行料的补充,尽量减少缩孔和疏松。 Solidified, and finally solidifying the spout itself, can cause solidification of the first solidified portion solidified material portions supplement, minimize shrinkage and osteoporosis. 目前,通常采用在模具上设置冷却装置,通过对模具进行冷却的方式来冷却铸件,控制铸件使其顺序凝固,同时,减少冷却时间,使铸件强度更好,现有技术的冷却装置一般为单一的风冷却或水雾冷却或水冷却,在冷却能力方面,水冷却最好,水雾冷却其次,风冷却最差,但是采用单一的冷却方式,无法较好的控制铸件的凝固顺序,若在后凝固的位置无法得到料的补充,就会出现缩孔、疏松等问题,导致产品报废。 At present, commonly used cooling means is provided on a mold, the mold is cooled by means of cooling the casting, so as to control the casting solidification, while reducing cooling time, a better strength of the casting, the prior art cooling apparatus is generally a single wind cooling or water cooling or mist cooling, cooling capacity, preferably the water cooling, water mist followed by cooling, air cooling the worst, but a single cooling method, the order can not be solidified casting better control, if the after solidification of the location can not be replenished material, there will be shrinkage, porosity and other issues, leading to product obsolescence.
