Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 2 to 3: the embodiment discloses a parallel liquid cooling die for producing an isolating ring, which comprises a plurality of matched die cores I1 and die cores II 2, wherein when the die cores I1 and the die cores II 2 are in butt joint, a cavity matched with the shape of the isolating ring is formed between the die cores I1 and II 2.

Wherein the first mold core 1 is connected with the template 4, and the second mold core 2 is also arranged on the corresponding second mold core template. On the basis, the present embodiment further includes an inner channel 3, wherein the second mold core 2 is provided with a liquid cooling channel 22, the mold plate 4 is provided with a first liquid flow channel 41, a partition plate 44, and a second liquid flow channel 42, which are sequentially arranged, the second mold core connecting surface of the mold plate 4 is provided with an inner channel mounting hole 43, the inner channel 3 is disposed in the liquid cooling channel 22, and the other end of the inner channel passes through the inner channel mounting hole 43 and the second liquid flow channel 42 sequentially and is connected to the partition plate 44.

In order to enhance the cooling effect, the first liquid flow channel 41 is a liquid inlet channel, and the second liquid flow channel 42 is a liquid outlet channel. This has the advantage of providing less resistance to the flow of liquid, which is beneficial to increasing the flow rate of the cooling liquid.

The channel 3 and the liquid cooling channel 22 are preferably arranged coaxially in this embodiment.

Wherein the inner channel 3 is preferably screwed to the partition 44.

The second mold insert 2 and the mold plate 4 are connected in the following way: the side part of the second mold core 2 is provided with a convex ring 21, the second mold core 2 is connected to the template 4 through a mold core fixing plate 5, the mold core fixing plate 5 is provided with an annular groove matched with the convex ring 21, and the convex ring 21 is pressed through the annular groove to realize the fixation of the second mold core 2 and the template 4.

Since the return passage needs to be formed between the inner passage mounting hole 43 and the liquid-cooling passage 22, the inner diameter of the inner passage mounting hole 43 is preferably equal to the inner diameter of the liquid-cooling passage 22.

In order to avoid liquid leakage, the connecting end of the template of the second mold insert 2 of this embodiment is further provided with a sealing ring groove 23, and a sealing ring 6 is further arranged in the sealing ring groove 23.

In order to increase the cooling length and avoid the phenomenon of too slow flow rate at the end of the liquid cooling channel 22 (the upper part in the view of fig. 3), the embodiment needs to limit the length of the inner channel 3 extending into the liquid cooling channel 22, so the distance (D in fig. 3) between the end of the inner channel 3 and the end of the liquid cooling channel 22 is not more than twice the outer diameter of the liquid cooling channel 22.

Because the mode of multiple mold positions is adopted, the number of the first mold core 1 and the second mold core 2 is 64, and all the second mold cores 2 are connected to the template 4.

In operation, the first fluid flow path 41 is connected to the inlet end of the liquid cooling device (prior art), as shown by the arrow in fig. 3: and cooling water enters the first liquid flow channel 41, then enters the liquid cooling channel 22 through the inner channel 3, and then flows back to the second liquid flow channel 42 from a gap between the liquid cooling channel 22 and the inner channel 3, and the second liquid flow channel 42 is communicated with the water inlet end of the liquid cooling device.

Compared with the prior art, in the embodiment, due to the parallel design, all the inner channels 3 are communicated with the first liquid flow channel 41, so that all the mold cores are simultaneously cooled by cooling water with the same temperature, the temperature is more uniform, the cooling effect is greatly improved, through the test, the cooling mode with the same flow is adopted, the cooling time of the mold can be reduced to 2-2.5S from 5-7S before, and the production is greatly improved.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
