In order to overcome the defects of the prior art, the utility model provides the centrifugal casting cooling water application device which is exquisite in structure, stable in cooling and reliable.

The utility model is realized by adopting the following technical scheme: the centrifugal casting cooling water application device comprises a jacket arranged outside a mold, wherein the inner wall of the jacket is attached to the outside of the mold, a water inlet pipe is arranged at the bottom of the jacket, cooling water is injected into the jacket through the water inlet pipe, a gap exists between the cooling water and the top of the inner side of the jacket, a plurality of accommodating grooves are annularly arranged on the outer wall of the mold and are arranged at intervals from top to bottom, a plurality of convex strips which correspond to the accommodating grooves in a one-to-one manner are arranged on the inner wall of the jacket, a motor is arranged at the bottom of the jacket, and the motor drives the rubber sleeve to rotate.

The bottom of the mould is provided with a stirring shaft, one end of the stirring shaft is fixedly connected with the mould, the other end of the stirring shaft extends to the inside of the jacket, and the other end of the stirring shaft is also provided with stirring blades which are arranged in the jacket.

And a sealing bearing is arranged on the inner wall of the rubber sleeve, and the other end of the stirring shaft penetrates through the sealing bearing.

And lubricating oil is arranged between the outer wall of the die and the inner wall of the jacket.

Compared with the prior art, the cooling device has the advantages that during work, the motor acts to enable the jacket to rotate around the die, forward rotation and reverse rotation of the jacket are achieved through forward rotation and reverse rotation control of the motor, cooling water in the jacket generates disturbance under the action of inertia, heat transmitted by the die through the jacket is absorbed by the cooling water, meanwhile, the heat is distributed more uniformly in the cooling water through the disturbance of the cooling water, the heat dissipation effect is improved, further, the disturbance speed of the cooling water in the jacket is effectively controlled through adjustment of conversion intervals of the rotating direction, the heat dissipation effect is controllable, mechanical properties of workpieces are not affected in the cooling and heat dissipation processes, and the cooling device is reasonable and exquisite in structure, stable and reliable.

FIG. 1 is a schematic structural view of the present invention;

in the figure: 1. a mold; 11. a containing groove; 12. a stirring shaft; 13. a stirring blade; 2. a jacket; 21. a convex strip; 22. sealing the bearing; 3. a water inlet pipe; 4. an electric motor.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

As shown in fig. 1, the device for applying cooling water by centrifugal casting includes a jacket 2 disposed outside a mold 1, an inner wall of the jacket 2 is attached to an outside of the mold 1, a water inlet pipe 3 is disposed at a bottom of the jacket 2, the water inlet pipe 3 injects cooling water into the jacket 2, a gap exists between the cooling water and a top portion of an inner side of the jacket 2, a plurality of accommodating grooves 11 are annularly disposed on an outer wall of the mold 1, the accommodating grooves 11 are spaced from top to bottom, a plurality of protruding bars 21 corresponding to the accommodating grooves 11 one by one are disposed on an inner wall of the jacket 2, a motor 4 is disposed at a bottom of the jacket 2, and the motor 4 drives the rubber sleeve to rotate. The motor 4 acts to enable the jacket 2 to rotate around the die 1, and the forward rotation and the reverse rotation of the jacket 2 are realized through the control of the forward rotation and the reverse rotation of the motor 4, so that cooling water in the jacket 2 generates disturbance under the inertia effect, heat transmitted by the die 1 through the jacket 2 is absorbed by the cooling water, meanwhile, the disturbance of the cooling water enables the distribution of the heat in the cooling water to be more uniform, and therefore the heat dissipation effect is improved, further, the disturbance speed of the cooling water in the jacket 2 is effectively controlled through the adjustment of the conversion interval of the rotation direction, and therefore the heat dissipation effect is controllable, and the mechanical property of a workpiece is not affected in the cooling and heat dissipation processes; the clearance between the cooling water and the top of the inner side of the jacket 2 ensures that the cooling water has enough space for disturbance; the arrangement of the accommodating groove 11 and the protruding strip 21 plays a role in limiting, and no displacement in the horizontal or vertical direction is ensured between the jacket 2 and the die 1.

The bottom of mould 1 is equipped with (mixing) shaft 12, the one end of (mixing) shaft 12 with mould 1 fixed connection, the other end of (mixing) shaft 12 extends to the inside of pressing from both sides cover 2, the other end of (mixing) shaft 12 still is equipped with stirring vane 13, stirring vane 13 is located the inside of pressing from both sides cover 2. The stirring shaft 12 and the stirring blades 13 are static relative to the mold 1 and rotate relative to the jacket 2, so that the disturbance effect of cooling water in the jacket 2 is improved, and heat dissipation is promoted.

The inner wall of the rubber sleeve is provided with a sealing bearing 22, and the other end of the stirring shaft 12 penetrates through the sealing bearing 22. The sealing bearing 22 is provided to support the stirring shaft 12 and prevent the cooling water from leaking to the outside of the jacket 2.

And lubricating oil is arranged between the outer wall of the die 1 and the inner wall of the jacket 2. Lubricating oil plays the lubrication action, has reduced the friction loss of clamp cover 2 and mould 1, and moreover, lubricating oil has filled the tiny gap between clamp cover 2 and the mould 1, promotes the heat dissipation.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
