DETAILED DESCRIPTION

[0022] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] A mold water channel structure according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown, for this purpose, one purpose of the present invention is to propose a mold water channel structure, including a mold cavity main body 100, the mold cavity main body 100 is provided with a plurality of water channel grooves 110, and also includes a water channel insert 200 arranged in the water channel groove 110, the water channel groove 110 and the water channel insert 200 cooperate to form a first cooling water channel 300, the bottom of the water channel groove 110 is equidistant from the molding cavity in the mold cavity main body 100, by arranging the insert and the water channel groove 110, the processing surface of the water channel groove 110 can be directly exposed, the bottom of the water channel groove 110 can be directly processed, so that the bottom of the water channel groove 110 is equidistant from the molding cavity in the mold cavity main body 100, that is, it can be close to the surface of the workpiece, so that the cooling efficiency is high, and the cooling can be made more uniform by arranging the water channel grooves 110, which can greatly reduce the production cycle and greatly reduce the deformation of the product. In addition, each first cooling water channel 300 can be independently controlled to ensure the diversity of injection molding process adjustment.

[0025] like Figure 3 As shown, the gap between the water channel insert 200 and the bottom of the water channel groove 110 forms a cooling section 310. One side of the water channel insert 200 and the side wall of the water channel groove 110 form a liquid inlet section 320, and the other side of the water channel insert 200 and the side wall of the water channel groove 110 form a liquid outlet section 330. The cooling section 310, liquid inlet section 320, and liquid outlet section 330 constitute the first cooling water channel 300. The loop has few turning points, which are easy to transition and can well adapt to the shape of the mold cavity, resulting in a good cooling effect. The water channel insert 200 is provided with a positioning hole 220 to facilitate the fixing and positioning of the water channel insert 200.

[0026] like Figures 4-5 As shown, the water channel insert 200 is equipped with a positioning block 210, and the water channel groove 110 is equipped with a stepped groove 120 that matches the positioning block 210. This can position the water channel insert 200 so that the distance between the water channel insert 200 and the bottom of the water channel groove 110 is maintained at a predetermined distance, ensuring the cross-sectional area of ​​the cooling section 310 and ensuring cooling efficiency. The mold cavity body 100 is equipped with a sealing ring 400 located outside the opening of the water channel groove 110 to ensure sealing.

[0027] The water channel insert 200 is provided with several detachable water blocks, which are located in the first cooling water channel 300. The water blocks can change the cross-sectional area of ​​the cooling section 310 and simply adjust the flow area of ​​the first cooling water channel 300. Combined with the flow rate adjustment, the injection molding process adjustment diversity can be further ensured.

[0028] The mold cavity body 100 is provided with a second cooling water channel 500. The second cooling water channel 500 can be a traditional cylindrical straight hole cooling water channel, which can directly cool the mold body, so that the first cooling water channel 300 can directly act on the mold cavity position, so as to achieve a better cooling effect.

[0029] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention.

[0030] The above technical solution has the following advantages or beneficial effects: by arranging the insert and the water channel groove 110, the processing surface of the water channel groove 110 can be directly exposed, and the bottom of the water channel groove 110 can be directly processed so that the bottom of the water channel groove 110 is equidistant from the molding cavity in the mold cavity body 100, that is, it can be close to the surface of the workpiece, so that the cooling efficiency is high, and the cooling can be made more uniform by arranging the water channel groove 110, which can greatly reduce the production cycle and the deformation of the product. In addition, each first cooling water channel 300 can be independently controlled to ensure the diversity of injection molding process adjustments.
