Description

Rotor mould with adjust pouring material velocity of flow

Technical Field

The utility model belongs to the technical field of the casting, concretely relates to rotor mold with adjust the pouring material velocity of flow.

Background

In general, a rotor generally refers to a rotating body supported by a bearing, and the rotor is a main rotating part in a power machine and a working machine. At present, a rotor is generally directly molded through a die casting, the process has the disadvantages of high raw material consumption, high operation difficulty, high production cost, poor stability of the manufactured product, rough and uneven surface and high product reject ratio. In the existing pouring type rotor mold at the present stage, the pouring material is in a liquid state before pouring, and when the liquid pouring material enters the mold, the flow velocity of the pouring material is difficult to ensure, so that the pouring material is difficult to stably and smoothly enter the mold, and finally, the condition that defects and even waste products occur in the cast rotor is caused.

In a casting mold for a motor rotor in the prior chinese patent CN 211101451U, "a plurality of the runners arranged at the bottoms of the cavities are eccentric funnel-shaped groove bodies inclined to the same side, and after casting, the pouring allowance forms an eccentric funnel-shaped structure corresponding to the runners inclined to the same side. Let pouring device from pouring nozzle when pouring into casting liquid to each runner, form spiral helicine pouring mode, in order to accelerate the casting liquid velocity of flow of pouring into, improve casting efficiency, this prior art has solved the problem that rotor casting efficiency is low through spiral helicine pouring mode, but this prior art accelerates the velocity of flow of pouring into casting liquid through a plurality of spiral helicine pouring modes of pouring into formation, a plurality of runners need pour into casting liquid simultaneously and can reach spiral helicine pouring mode, just also can not reach the effect of accelerating the casting liquid velocity of flow if a plurality of runners can not pour into casting liquid simultaneously and just scatter and disappear, casting efficiency also can not be promoted, and accelerate the condition that the casting liquid velocity of flow must make the casting liquid spill over, thereby cause the waste of casting liquid.

In summary, in the prior art, the flow rate of the casting liquid is increased by the spiral pouring method, which not only causes the waste of the casting liquid, but also increases the casting cost because the spiral pouring method can be formed by injecting a plurality of runners simultaneously, and reduces the flow path of the molten iron through the linear pouring channel, which not only damages the cavity due to the too fast flow rate of the molten iron, but also causes the quality problems such as the defect of the cast rotor due to the damage of the cavity. For this reason, a new technical solution is needed to solve the above technical problems.
