[0027] Before describing the embodiments of the present invention in detail, the application environment of the present invention will be described first. The technology of the present invention is mainly applied to the field of molding die technology. The present invention is used to solve the problem that the cooling efficiency of the traditional cooling water circuit of the die is relatively low, resulting in a long cooling time and affecting the production cycle and output.

[0028] Please refer to Figures 1 to 6 As shown, the present invention provides a conformal waterway structure for the female mold of a screen back cover molding die.

[0029] In an exemplary embodiment of the present application, the conformal waterway structure for the female mold of a screen back cover molding die includes: a first half mold 1, on which a coolant inlet 101 and a coolant outlet 102 are provided.

The coolant flows through the first cooling water chamber 3 and flows out of the first cooling water chamber 3 through the coolant outlet 102, thereby taking away heat. Since the cooling area of the first cooling water chamber 3 formed in this application is consistent with the molding area of the molding groove 201, the coolant can take away heat more effectively, thereby improving the cooling efficiency, reducing the cooling time, shortening the production cycle, and increasing the output.

[0043] In an exemplary embodiment of the present application, the height of the convex portion 202a along the thickness direction of the second half mold 2 is greater than the depth of the cooling water tank 202.

[0044] In this embodiment, by designing the height of the convex portion 202a to be greater than the grooving depth of the cooling water tank 202, the convex portion 202a can extend into the groove 105a to cooperate with the groove 105a, thereby separating the first cooling water cavity 3 to form multiple cooling channels. Moreover, the convex portion 202a on the second half mold 2 cooperates with the groove 105a on the first half mold 1, so that the convex portion 202a can support the first half mold 1, avoiding the collapse and deformation of the first cooling water cavity 3 after the master mold is used for a long time, thereby being able to maintain the normal operation of the cooling water cavity for a long time, and effectively avoiding the influence of the collapse and deformation of the first half mold 1 on the molding of the product.

[0045] In an exemplary embodiment of the present application, the second half mold 2 is provided with first bolt connection holes 204 around the positioning groove 203, the first bolt connection holes 204 are correspondingly arranged with the first through holes 107, and the second half mold 2 and the main mold table 104 are correspondingly provided with positioning holes 5.

[0047] In an exemplary embodiment of the present application, the sprue 4 is provided with a second sealing groove 402 around the second cooling water cavity 401, and the sprue 4 is provided with second bolt connection holes 403 around the second sealing groove 402.

[0048] In this embodiment, the second sealing groove 402 is used to install a sealing component, such as a sealing ring. The cover plate is connected to the second bolt connection holes 403 arranged around the second sealing groove 402 through screws passing through the second through holes provided on the cover plate, thereby closing the second cooling water chamber 401. The cover plate is extruded by the screws, and the cover plate extrudes the sealing component arranged in the second sealing groove 402, thereby providing a pre-tightening force between the sealing component and the cover plate, so that the sealing component arranged in the second sealing groove 402 meets the sealing effect of the second cooling water chamber 401.

[0049] In another exemplary embodiment, both the first half mold 1 and the second half mold 2 are made of CENA1 (mirror plastic film steel) material.

[0051] Working principle: In this application, the first half mold 1 and the second half mold 2 are connected to form a conformal water channel structure of the female mold of the screen back cover forming mold. The first cooling water chamber 3 is formed by the cooperation of the cooling flow field 103 provided on the first half mold 1 and the cooling water tank 202 provided on the second half mold 2. Since the cooling water tank 202 is arranged corresponding to the forming groove 201, the cooling area of the formed first cooling water chamber 3 is consistent with the forming area of the forming groove 201. The coolant is introduced into the first cooling water chamber 3 through the coolant inlet 101 provided on the first half mold 1. The coolant flows through the first cooling water chamber 3 and flows out of the first cooling water chamber 3 through the coolant outlet 102, thereby taking away heat. Since the cooling area of the first cooling water chamber 3 formed in this application is consistent with the forming area of the forming groove 201, the coolant can take away heat more effectively, thereby improving the cooling efficiency, reducing the cooling time, shortening the production cycle, and increasing the output.
