[0020] The terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned accompanying drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, mechanism, product or end that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or ends.

[0021] Referring to "embodiment" herein means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of the present utility model. The phrase appears at various positions in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] The present utility model discloses a specific implementation manner of a cooling water channel structure for an automotive injection mold. Please refer to Figures 1 to 3 , which includes a mold body 1 and a water transfer block 2.

[0023] In this embodiment, an installation groove 10 is opened on the top surface of the mold body 1, and the water transfer block 2 is detachably installed in the installation groove 10. Optionally, two fixed holes arranged at intervals are opened in the middle of the water transfer block 2. To avoid the nut of the bolt protruding from the surface of the water transfer block 2, the fixed holes are set as counterbore holes 20. The water transfer block 2 can be detachably installed in the installation groove 10 of the mold body 1 by opening corresponding locking holes, such as threaded holes, on the mold body 1 and using bolts. Preferably, both the water transfer block 2 and the installation groove 10 are rectangularly arranged, which is more convenient for processing and installation.

[0024] In this embodiment, an installation hole for installing an external hot nozzle is formed between the side surface of the water transfer block 2 and the groove wall of the installation groove 10. As a preferred solution, a first semi-circular hole 13 is formed in the groove wall of the installation groove 10, and a second semi-circular hole 23 opposite to the first semi-circular hole 13 is formed on the outer side surface of the water transfer block 2. The first semi-circular hole 13 and the second semi-circular hole 23 together enclose the installation hole. To fix the external hot nozzle more firmly, there are two counterbore holes 20, which are respectively located on both sides of the second semi-circular hole 23.

[0025] As a further improvement, as Figure 1 and Figure 3 shown, a cooling water channel 14 is formed inside the mold body 1. The cooling water channel 14 includes a water inlet 11 and a water return port 12. The water inlet 11 and the water return port 12 are arranged at intervals and are provided at the bottom of the installation groove 10. Of course, according to needs, the water inlet 11 and the water return port 12 can also be arranged on the groove wall of the installation groove 10. As Figure 2 shown, a water inlet 21 communicating with the water inlet 11 and a water outlet 22 communicating with the water return port 12 are provided on the bottom surface and / or the side surface of the water transfer block 2. A cooling channel 24 is also formed inside the water transfer block 2, and the cooling channel 24 communicates with the water inlet 21 and the water outlet 22 respectively.

[0026] During operation, the cooling liquid enters the water inlet 21 of the water transfer block 2 from the water inlet 11, flows out from the water outlet 22 of the water transfer block 2 after passing through the cooling channel 24, and enters the water return port 12 to achieve circulation, so as to cool the water transfer block 2 and further achieve rapid cooling of the hot nozzle.

[0027] To make the layout of the cooling channel 24 in the water transfer block 2 more comprehensive and uniform, the cooling channel 24 is arranged in a U shape to increase the length of the cooling channel 24 as much as possible. The U-shaped opening of the cooling channel 24 faces the installation hole, and the counterbore hole 20 is located between the cooling channel 24 and the installation hole, so as to have a certain distance between the cooling channel 24 and the installation hole, avoiding weakening the structural strength of the water transfer block 2 due to the setting of the cooling channel 24, and thus unable to effectively install and fix the external hot nozzle. In addition, the water inlet 21 and the water outlet 22 are respectively located at both ends of the U-shaped opening of the cooling channel 24, so that all the water in the cooling channel 24 can circulate, avoiding dead corners in the cooling channel 24.

[0028] In this embodiment, the water transfer block 2 can also be provided with four sub-channels 25, Figure 2Three sub-channels 25 are shown, with one end of each sub-channel 25 communicating with the cooling channel 24. The other end of the sub-channel 25 penetrates through any side surface or the bottom surface of the water turning block 2, so that the other end of the sub-channel 25 can communicate with the cooling water channels 14 in other directions of the mold body 1, enabling the water flow in the water turning block 2 to not only flow in and out at the water inlet 11 and the water return port 12, but also flow in and out through the cooling water channels 14 in other directions, further accelerating the cooling rate.

[0029] Compared with the prior art, in this application, by providing the water turning block 2, a cooling channel 24 is opened inside the water turning block 2 and is in communication with the cooling water channel 14 of the mold body 1. The cooling channel 24 can quickly take away the heat of the external hot nozzle, thereby accelerating the cooling rate at the hot nozzle. The cooling channel 24 becomes a part of the cooling water channel 14, thus shortening the distance between the cooling water channel 14 and the hot nozzle, shortening the cooling time, improving economic benefits, and solving the problem that the hot nozzle is poorly cooled due to the long distance between the conventional cooling water channel 14 and the hot nozzle.

[0030] Finally, it should be noted that: what is disclosed in the cooling water channel structure for an automotive injection mold according to the embodiments of the present utility model is only the preferred embodiments of the present utility model, only for explaining the technical solutions of the present utility model, rather than limiting it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
