Dummy bar head lifting platform 5: mainly consists of four major parts: lifting platform, support, dummy bar head 7, lift fixed axle 503.
The lifting fixing shaft 503 is matched with the fixing frame 1 to play a role in guiding, so that the crystallization head 6 and the dummy bar head 7 are preliminarily matched.
The dummy bar head support is used for installing a dummy bar head 7, the height of the dummy bar head 7 needs to be guaranteed to be uniform after installation, and the radial energy of the dummy bar head 7 can be adjusted in a small range under the action of the guide block and is used for accurately assembling a crystallization head 6 and the dummy bar head 7 before aluminum bar casting.
The aluminum bar casting mould plate is equipment for casting aluminum bars with the same specification in batches.
The working principle of the aluminum bar casting mold disc is as follows: the aluminum water in the casting diversion channel 4 is effectively and synchronously sucked into each mould disc unit 3 through electrical control, and then is uniformly distributed on each dummy head 7 to be cooled and crystallized to form aluminum bars, so that the batch casting of the aluminum bars is realized.
The aluminum bar casting die plate needs to be subjected to two-step die assembly before use:
the dummy bar head platform is lifted quickly, and the crystallization head 6 and the dummy bar head are preliminarily matched by using the lifting fixing shaft 503.
And then slowly lifting the dummy bar head platform, and leading the crystallization head 6 and the dummy bar head to be accurately matched through the guiding on the circumference of the dummy bar head (the upper plane of the dummy bar head is contacted with the graphite ring).
After the mold closing is finished (the upper plane of the dummy bar head 7 is contacted with the graphite ring), the equipment can be started to start casting.
In the actual use process:
dummy bar head lift platform 5's bottom install its hydro-cylinder that rises or descend of drive, when needs dummy bar head 7 and the first 6 cooperation work of crystallization, the whole dummy bar head lift platform of hydro-cylinder drive 5 rises for every dummy bar head 7 stretches into to the crystallization in the head 6.
The initial positions of the single crystallization head 6 and the dummy head 7 during working are shown in fig. 18, molten aluminum enters through the die disc unit 3 and then is fed from the through hole 601 of the hot top 602, the molten aluminum enters into the forming area between the crystallization head 6 and the dummy head 7 from the through hole 601, the molten aluminum is slowly solidified to form an aluminum shell, and under the action of an external oil cylinder, the dummy head 7 is controlled to slowly and gradually move downwards, namely the oil cylinder is driven to work, and the whole dummy head lifting platform 5 is controlled to descend, so that a cylindrical aluminum rod is formed. In the forming process, the oil inlet graphite ring 605 is used for oil inlet lubrication treatment, the air inlet graphite ring 606 is used for uniformly mixing and treating the inlet air and the oil, the cooling water is introduced into the water inlet hole 608 for synchronous cooling, the cooling effect is good, and the forming effect is good. And when the aluminum bar is molded to the required height, stopping feeding the aluminum water, and taking away the aluminum bar. And performing the next cycle by adopting the same method.
The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made within the scope of the invention.
