Description

一种模具风水混合冷却系统及带有该系统的低压轮毂模具Mould Fengshui mixed cooling system and low pressure wheel mold with the same 技术领域Technical field
本发明涉及汽车轮毂模具技术领域,尤其涉及一种用于冷却模具的风水混合冷却系统及带有该冷却系统的低压轮毂模具。The invention relates to the technical field of automobile wheel hub molds, in particular to a feng shui mixed cooling system for cooling a mold and a low pressure hub mold with the same.
背景技术Background technique
现有汽车轮毂模具风冷却结构是通过4-6kgf(千克力)压力的压缩空气作用在模具的冷却终端来带走汽车轮毂模具的热量,以达到降低模具温度的目的。但此种冷却方式的冷却速率较慢,会导致模具开模时间的延长,从而影响产品的生产效率及产品材料的机械性能。The existing automobile wheel mold air cooling structure uses the compressed air of 4-6 kgf (kilogram force) pressure to act on the cooling terminal of the mold to take away the heat of the automobile hub mold, so as to reduce the mold temperature. However, the cooling rate of this cooling method is slow, which leads to prolonged mold opening time, which affects the production efficiency of the product and the mechanical properties of the product material.
现有技术中有将压缩空气改为混合雾化后的水蒸汽对冷却终端进行冷却的方法,虽然水蒸气较压缩空气的冷却效果好,但是水蒸汽残留在通道中一方面导致生锈,另一方面残留的位置也会导致冷却效果不均匀。In the prior art, there is a method of cooling the cooling terminal by changing the compressed air to the mixed atomized water vapor. Although the cooling effect of the water vapor is better than that of the compressed air, the water vapor remains in the passage and causes rust on the other hand. On the one hand, the residual position also causes uneven cooling effect.

The cooling circulating water with a pressure of 2.5-3 kgf flows through the cooling terminal on the above four sets of molds, at the split cone water cooling terminal 21, the side water front cooling water terminal 26, the lower mold slope water cooling terminal 28, and the lower mold rib tip water cooling terminal After the circulating water is cooled by 210, compressed air is introduced to prevent the cooling water from staying in the mold cooling terminal to continue to cool the mold or form a vapor pressure in the cooling terminal, thereby affecting the water flow of the next cycle.
而安挂面风冷却终端22、安装盘风冷却终端23、上模斜坡风冷却终端24及上模后挂风冷却终端25、下模PCD风冷却终端27、下模肋中风冷却终端29则在冷却过程中采用风冷。The installation surface air cooling terminal 22, the installation air cooling terminal 23, the upper mold slope air cooling terminal 24, the upper mold rear air cooling terminal 25, the lower mold PCD air cooling terminal 27, and the lower mold rib stroke cooling terminal 29 are cooled. Air cooling is used in the process.
使用该模具生产轮毂过程为,模具完成合模后,模具底部坩埚中的铝水在压缩气体的作用下,由升液管经下模的浇口进入模具型腔内,在模具上的各个冷却终端的作用下,铝水温度降低,进而达到凝固状态并按顺序进行凝固,最后打开模具将轮毂毛坯取出。The process of using the mold to produce the hub is: after the mold is clamped, the aluminum water in the bottom of the mold is compressed by the gas, and the liquid rises into the mold cavity through the gate of the lower mold, and each cooling on the mold Under the action of the terminal, the temperature of the aluminum water is lowered, and then the solidified state is reached and solidified in order, and finally the mold is opened to take out the hub blank.
本实施方式低压轮毂模具由于在热节位置设置冷却终端,因此在不增加辐条和浇口部位温度的情况下就能满足铸件的顺序凝固条件,从而缩短了产品的制造周期,提高生产效率,由于可使铸件快速冷却凝固,有效缩短铸件晶粒长大时间,从而使产品的机械性能与普通冷却相比提高10%以上,使产品生产效率比普通风冷提高1.5-2倍;生产的合格率提高5%以上。 Since the low-pressure hub mold of the present embodiment is provided with a cooling terminal at the hot joint position, the sequential solidification condition of the casting can be satisfied without increasing the temperature of the spokes and the gate portion, thereby shortening the manufacturing cycle of the product and improving the production efficiency due to The casting can be quickly cooled and solidified, effectively shortening the casting grain growth time, so that the mechanical properties of the product can be increased by more than 10% compared with the ordinary cooling, so that the production efficiency of the product is 1.5-2 times higher than that of the ordinary air cooling; the qualified rate of production Increase by 5% or more.
