Example 1

Referring to fig. 1, 2, 3, 4, 5, 7 and 8, a spot cooling pipeline includes:

The first pipe fitting 1, the first pipe fitting 1 is annular, and a plurality of first branch pipes 2 are arranged on the first pipe fitting 1;

The second pipe fitting 3, the second pipe fitting 3 is annular, a plurality of second branch pipes 4 are arranged on the second pipe fitting 3;

The first branch pipes 2 are in one-to-one correspondence with the second branch pipes 4, the first branch pipes 2 penetrate through the second pipe fitting 3 and then are inserted into the second branch pipes 4, and gaps are formed between the outer walls of the first branch pipes 2 and the inner walls of the second branch pipes 4.

The first branch pipe 2 communicates with the first pipe member 1, and the second branch pipe 4 communicates with the second pipe member 3.

It should be noted that, the connection between the first branch pipe 2 and the second pipe 3 needs to be sealed, and the first branch pipe 2 may be connected to the second pipe 3 by welding.

As a further scheme, the first pipe fitting 1 and the second pipe fitting 3 are arranged up and down oppositely, and the first branch pipe 2 and the second branch pipe 4 are arranged along the vertical direction.

As can be seen from fig. 3, the outer diameter of the first tube member 1 is smaller than the outer diameter of the second tube member 3. The first branch pipe 2 is inserted in a vertical direction into a vertically disposed second branch pipe 4. In this way, on the one hand, the processing of the various parts is convenient, and on the other hand, the assembly is facilitated.

The ratio of the outer diameter of the first pipe member 1 to the outer diameter of the second pipe member 3 is not limited, and may be specifically set as required.

As a further solution, the first branch pipe 2 is arranged inclined away from the opening at one end of the first pipe member 1. This design can avoid the problem of clogging of the cooling medium after the first branch pipe 2 is completely inserted into the stepped hole 6.

As a further scheme, a necking 5 is arranged at the joint of the second pipe fitting 3 and the second branch pipe 4, and a gap is formed between the necking 5 and the outer wall of the first branch pipe 2. This design increases the pressure of the cooling medium remaining in the outer wall of the first branch pipe 2 and the second branch pipe 4, contributing to an increase in the rate of discharge of the cooling medium, which completes the heat exchange, into the second pipe member 3.

As a further solution, the first tube member 1 is provided with a liquid inlet tube 8. Through the feed pipe 8, a cooling medium can be fed into the first pipe member 1.

As a further solution, the second tube member 3 is provided with a liquid outlet tube 9. The cooling medium in the second pipe 3 can be discharged through the liquid outlet pipe 9.

The cooling medium in the present embodiment is not limited to this, and the purpose of the present invention is to be able to exchange heat with the mold. Specifically, gas, tap water, cooling liquid, etc. can be selected.

Example 2

Referring to fig. 6, the present utility model also provides a connection device based on the same inventive concept. The connection device connects the cooling line of example 1 with the spot cooling hole of the mold, and supplies the cooling medium to the spot cooling hole of the mold.

The connecting device comprises:

The cooling circuit of example 1;

A step hole 6, the step hole 6 being provided on the mold;

And the connecting pipe 7, the connecting pipe 7 is fixed in the large hole of the step hole 6, and the second branch pipe 4 is communicated with the connecting pipe 7.

The connection pipe 7 and the large hole of the stepped hole 6 need to be sealed. Specifically, the connecting pipe 7 and the large hole of the stepped hole 6 can be welded or screwed. When the threaded connection is adopted, the threaded connection part is required to be sealed by adopting a raw material belt or sealant.

As a further scheme, the small hole of the step hole 6 is spherical crown-shaped. The small holes of the step holes 6 are arranged in a spherical crown shape, so that the contact area between the cooling medium and the step holes 6 can be increased, and the small holes in the spherical crown shape have better pressure resistance and can bear the impact of the cooling medium.

As a further solution, the end of the second branch pipe 4 remote from the second pipe member 3 is fixed in the connecting pipe 7, and the depth of the first branch pipe 2 inserted into the connecting pipe 7 is larger than the depth of the second branch pipe 4 inserted into the connecting pipe 7. The depth of the first branch pipe 2 inserted into the connecting pipe 7 is larger than the depth of the second branch pipe 4 inserted into the connecting pipe 7, so that the cooling medium which does not exchange heat is beneficial to contact with the stepped hole 6, and the cooling medium after heat exchange is also beneficial to being discharged along the second branch pipe 4.

The second branch pipe 4 may be sleeved on the outer wall of the connecting pipe 7.

Specifically, the cooling medium enters the first pipe fitting 1 through the liquid inlet pipe 8, then enters the connecting pipe 7 through the first branch pipe 2, exchanges heat after contacting with the inner wall of the stepped hole 6, takes away the heat of the die, enters the second pipe fitting 3 through the second branch pipe 4, and is discharged through the liquid outlet pipe 9.

It should be noted that, the product produced in the present utility model is a hub, and a plurality of cooling points thereof are distributed along the same circumferential direction, so the annular first pipe fitting 1 and the annular second pipe fitting 3 in the present embodiment can meet the cooling requirements of the plurality of cooling points.

Obviously, the inventive pipe may also be used when the mold cooling points of other products are in the same circumference.

Obviously, in the above embodiment, the connection pipe 7 is a straight pipe and is disposed in the vertical direction.

As shown in fig. 7, the first pipe member 1 and the second pipe member 3 may be disposed horizontally opposite to each other, and in this case, the connection pipe 7 is required to be L-shaped in order to supply the cooling medium to the mold.

Obviously, the first pipe fitting 1 and the second pipe fitting 3 may also be arranged at an angle.

When the plurality of cooling points are offset in the same circumferential direction, a connecting pipe 7 as shown in fig. 8 may be used, the connecting pipe 7 having one horizontal end 10 and two vertical ends 11, the two vertical ends 11 being disposed on both sides of the horizontal end 10, the connecting pipe 7 being capable of compensating for the offset of the cooling point offset.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
