[0017] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0018] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "central", "end portion", "length", "outer end", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0019] Combined with the attached Figures 1 to 5 As shown, this embodiment discloses an injection mold cavity cooling waterway structure, including four cavity inserts 3, a cavity waterway 7, water inlet and outlet holes 4, a connection groove 5 and a water sealing block 6. Among them, every two inserts are in a group, and the two inserts in the same group are symmetrically arranged up and down, and the two groups of inserts are perpendicular to each other and lean together. Cavity waterways 7 are arranged in all four cavity inserts 3, and the cavity waterways 7 in the four cavity inserts 3 are independent of each other and have the same waterway structure.

[0020] Two water inlet and outlet holes 4 are arranged on the cavity insert 3, one for water inlet and one for water outlet. The water inlet and outlet holes 4 are communicated with the cavity waterway 7, and each cavity insert 3 has independent water inlet and outlet holes 4. The water inlet and outlet holes 4 are connected to the water inlet and outlet valves on the injection molding machine.

[0021] A plurality of connecting grooves 5 are provided on the front and rear surfaces of the cavity insert 3. The connecting grooves 5 communicate with the cavity water channels 7. A water sealing block 6 is provided on the connecting grooves 5. The connecting grooves 5 are arranged in a circumferential pattern on the cavity insert 3. The cavity water channels 7 include multiple straight water channels 9. Each section of the straight water channels 9 is parallel to each other. The straight water channels 9 are connected together through the connecting grooves 5 to form an arched water channel structure. The connecting grooves 5 serve as the connecting channels for the straight water channels. The arched water channels increase the flowing time of the cooling water within the cavity insert, improving the cooling effect.

[0022] The function of the water sealing block 6 is to block the outside of the connecting groove 5, enabling the cooling water to flow within the cavity insert 3 without leakage. The thickness of the water sealing block 6 is one-third of the depth of the connecting groove 5, ensuring that the water sealing block 6 does not completely seal the connecting groove 5, only occupying 1 / 3 of the depth of the connecting groove 5 to ensure unobstructed water flow. The surface of the water sealing block 6 is flush with the surface of the cavity insert 3. The water sealing block 6 is connected to the cavity insert 3 by means of electric welding or argon arc welding.

[0023] Small holes 8 are provided on the side surface of the cavity insert 3. The small holes 8 communicate with the cavity water channels 7 and the water inlet and outlet holes 4 respectively. A plug 2 is provided at the outlet end of the small holes 8. The function of the small holes 8 is to connect the two ends of the arched cooling water channels within the cavity insert 3 to the water inlet and outlet holes 4 to play a transitional role. After being connected together, the outlet end of the small holes 8 is sealed with a special plug 2 to form a complete cavity insert water channel cooling structure.

[0024] The working process of the present utility model is as follows: The water inlet and outlet holes 4 are connected to the water inlet and outlet valves on the injection molding machine. The cooling water enters the mold and runs along the arched cavity water channels to uniformly cool the cavity towards the water outlet. The present utility model is convenient for processing and can be widely applied to various injection molding molds.
