[0025] The present utility model will be described in detail below with reference to the attached drawings and specific embodiments.

[0026] Refer to Figures 1 to 7As shown in the figure, the utility model provides a mold structure convenient for water transportation. In one embodiment, it includes a B plate 1 and a rear mold core 2. A first installation groove 6 is opened at the top of the B plate 1, and the rear mold core 2 is installed in the first installation groove 6. A first card slot is further opened in the first installation groove 6, and a first water transportation insert 3 is embedded in the first card slot. One end of the bottom of the first water transportation insert 3 is vertically provided with a first water transportation port 31, and one end of the top of the first water transportation insert 3 away from the first water transportation port 31 is vertically provided with a second water transportation port 32. A first water transportation flow channel 33 communicating with the first water transportation port 31 and the second water transportation port 32 is horizontally opened in the first water transportation insert 3. A first water injection port 34 is further opened on one side of the B plate 1, and a second water transportation flow channel 35 with two ends respectively communicating with the first water injection port 34 and the first water transportation port 31 is horizontally opened in the B plate 1 along its width direction. A first water outlet 36 communicating with the second water transportation port 32 is opened at the position corresponding to the bottom of the rear mold core 2.

[0027] To cool the product, generally, water transportation is drilled inside the rear mold core 2 to facilitate the cooling and forming of the product. However, the water transportation in the rear mold core 2 needs to be connected to the B plate 1 for water transportation to be connected to the external cooling water device. Due to various irresistible factors, when the connection between the internal water transportation of the rear mold core 2 and the water transportation of the B plate 1 cannot be properly docked (i.e., misaligned), the water transportation insert can be used to dock the water transportation of the rear mold core 2 and the transportation of the B plate 1 (at this time, the water transportation insert plays a role of a bridge docking), as Figures 4 - 5 shown. Connect the external cooling water device through the first water injection port 34. The flow path of the cooling water is: first water injection port 34 - second water transportation flow channel 35 - first water transportation port 31 - first water transportation flow channel 33 - second water transportation port 32 - first water outlet 36.

[0028] In one embodiment, the first water transportation insert 3 is in a cuboid structure. Designing the first water transportation insert 3 in a cuboid structure is convenient for the processing of the flow channel and the installation of the water transportation insert.

[0029] In one embodiment, a second card slot is further formed in the first installation groove 6, and a second water delivery insert 4 is further embedded in the second card slot; third water delivery ports 41 and fourth water delivery ports 42 are respectively formed at both ends of the top of the second water delivery insert 4 in the vertical direction, and a third water delivery flow channel 43 communicating with the third water delivery ports 41 and the fourth water delivery ports 42 is further formed in the second water delivery insert 4 in the horizontal direction; a fourth water delivery flow channel 44 communicating with the fourth water delivery ports 42 is further formed at the bottom of the rear mold core 2 in the vertical direction; a fifth water delivery flow channel 45 communicating with the fourth water delivery flow channel 44 is further formed in the rear mold core 2 in the horizontal direction, and a sixth water delivery flow channel 46 communicating with the fifth water delivery flow channel 45 is formed at the bottom of the rear mold core 2 in the vertical direction; a second water injection port 47 is formed on the other side of the B plate 1, and a seventh water delivery flow channel 48 is further formed in the B plate 1 in the horizontal direction; an eighth water delivery flow channel 49 whose two ends are respectively communicated with the sixth water delivery flow channel 46 and the seventh water delivery flow channel 48 is formed in the B plate 1 in the vertical direction; a second water outlet 40 is further formed at the bottom of the rear mold core 2 corresponding to the third water delivery ports 41 in the vertical direction.

[0030] As Figures 6 - 7 shown, by connecting an external cooling water device through the second water injection port 47, the flow path of the cooling water is: second water injection port 47 - seventh water delivery flow channel 48 - eighth water delivery flow channel 49 - sixth water delivery flow channel 46 - fifth water delivery flow channel 45 - fourth water delivery flow channel 44 - fourth water delivery ports 42 - third water delivery flow channel 43 - third water delivery ports 41 - second water outlet 40.

[0031] In one embodiment, gaps are left between the four corners of the first water delivery insert 3 and the inner wall of the first card slot; a bayonet 5 protruding outward in a semi-circular structure is provided at each of the four corners of the first card slot, and each of the four corners of the first water delivery insert 3 is arranged in a bayonet 5. Gaps are left between the four corners of the first water delivery insert 3 and the inner wall of the first card slot, which is convenient for disassembly and replacement.

[0032] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
