Description

Technical Field

[0001] The utility model relates to a mold cooling structure, in particular to a mold cooling structure. Background Art

[0002] During the use of the mold for injection molding, it is necessary to use coolant to cool down the mold in order to reduce the temperature of the mold. In the prior art, cooling is often only used for the mold. For the mold core, heat is generally transferred to the corresponding mold through heat transfer to achieve cooling. Such cooling efficiency is low, which affects the injection molding efficiency to a certain extent. Utility Model Content

[0003] Based on this, it is necessary to provide a mold cooling structure to address the problems in the prior art.

[0004] A mold cooling structure is characterized in that it includes an upper mold and a mold core, the upper mold is wrapped around the outer side of the mold core, an inner cooling channel is provided in the mold core, an outer cooling channel is provided in the upper mold, and the outer cooling channel is connected to the inner cooling channel.

[0005] In one of the embodiments, the upper mold is provided with a receiving cavity, and the mold core is fixed in the receiving cavity.

[0006] In one of the embodiments, the external cooling channel of the upper mold extends to the position of the accommodating cavity, a positioning boss is provided at the bottom of the accommodating cavity, and a corresponding positioning groove is provided on the upper side of the mold core. When the mold core is set in the position of the accommodating cavity, the positioning groove of the mold core is arranged opposite to the positioning boss at the bottom of the accommodating cavity.

[0007] In one embodiment, a sealing groove is provided at the location of the positioning boss or positioning groove, and a sealing ring is clamped at the location of the sealing groove.

[0008] In one embodiment, the inner cooling channel is a closed channel having a first inlet and a first outlet, and the outer cooling channel is two independent first channels and second channels, and the first channels and the second channels are closed and arranged corresponding to the first inlet and the first outlet.

[0009] In one embodiment, the first channel and the second channel are provided with connection nozzles communicating with the connection at positions away from the mold core.

[0010] In one embodiment, the upper mold and the mold core are connected and fixed by fasteners.

[0011] The above-mentioned mold cooling structure respectively sets an external cooling channel and an internal cooling channel on the mold core and the outer upper mold, and connects the two cooling channels. In this way, the mold core can be cooled during use, thereby preventing the temperature of the mold core from being too high during use, thereby improving production efficiency and extending the service life of the mold.

[0016] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0017] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only."

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0019] like Figures 1 to 3As shown, a mold cooling structure is characterized in that it includes an upper mold 1 and a mold core 2, the upper mold 1 is wrapped around the outer side of the mold core 2, the mold core 2 is provided with an inner cooling channel 4, the upper mold 1 is provided with an outer cooling channel 3, and the outer cooling channel 3 and the inner cooling channel 4 are connected.

[0020] An outer cooling channel 3 and an inner cooling channel 4 are respectively provided on the mold core 2 and the outer upper mold 1, and the two cooling channels are connected, so that the mold core 2 can be cooled during use, thereby preventing the temperature of the mold core 2 from being too high during use, thereby improving production efficiency and extending the service life of the mold.

[0021] At this time, the upper mold 1 is provided with an accommodating cavity 11, and the core 2 is fixed in the accommodating cavity 11. Furthermore, the outer cooling channel 3 of the upper mold 1 extends to the position of the accommodating cavity 11, and a positioning boss is provided at the bottom of the accommodating cavity 11, and a corresponding positioning groove is provided on the upper side of the core 2. When the core 2 is set in the position of the accommodating cavity 11, the positioning groove of the core 2 is arranged opposite to the positioning boss at the bottom of the accommodating cavity 11. The upper mold 1 and the core 2 are positioned at the positioning boss and the positioning groove. During use, the outer cooling channel 3 and the inner cooling channel 4 can be easily aligned, and at the same time, it is not easy to move after alignment.

[0022] Furthermore, the upper mold 1 and the mold core 2 are connected and fixed by fasteners, so that the upper mold 1 and the mold core 2 are better fixed together.

[0023] In order to avoid water leakage at the connection between the outer cooling channel 3 and the inner cooling channel 4, in the present embodiment, a sealing groove is provided at the positioning boss or positioning groove, and a sealing ring is clamped at the sealing groove. The sealing ring can further increase the sealing effect, thereby avoiding water leakage.

[0024] The outer cooling channel 3 and the inner cooling channel 4 are used to cool the mold and the core 2. In the present embodiment, the inner cooling channel 4 is a closed channel having a first inlet and a first outlet, and the outer cooling channel 3 is two independent first channels and second channels, and the first channels and the second channels are closed and arranged corresponding to the first inlet and the first outlet.

[0025] In order to facilitate the connection of the external cooling channel 3 with the outside, in this embodiment, the first channel and the second channel are provided with connection nozzles communicating with the connection at positions away from the mold core 2 .
