[0025] Before describing the embodiments of the present utility model in detail, the application environment of the present utility model will be described first. The technology of the present utility model is mainly applied to the field of molding die technology. The present utility model is used to solve the problem that the cooling efficiency of the traditional cooling water channel of the die is relatively low, resulting in a long cooling time and affecting the production cycle and output.

[0026] Please refer to Figures 1 to 4 As shown, the present utility model provides a conformal water channel structure for the female die of a main engine upper cover molding die.

[0027] In an exemplary embodiment of the present application, the conformal water channel structure for the female die of the main engine upper cover molding die includes: a first half die 1, on which a cooling flow field 101, a coolant inlet 102, and a coolant outlet 103 are provided. The coolant inlet 102 and the coolant outlet 103 are communicated with the cooling flow field 101, and a first through hole 104 is provided on the first half die 1; a second half die 2, which is connected to the first half die 1. On both sides of the second half die 2 in the thickness direction, a molding surface 201 and a cooling water tank 202 are provided respectively.

The coolant flows through the cooling water cavity and flows out of the cooling water cavity through the coolant outlet 103, thereby taking away heat. The glue is injected through the glue injection channel formed by the combination of the first through hole 104 and the second through hole 203, and the glue is injected into the molding surface 201 through the glue injection channel. Since the cooling area of the cooling water cavity formed in this application is basically the same as the molding area of the molding surface 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.

[0036] In this embodiment, by arranging a sealing ring in the first sealing groove 204a and making the first limiting platform 204 in abutting and cooperating connection with the first limiting groove 106a, the sealing ring in the first sealing groove 204a is extruded and sealed, so as to prevent the coolant in the cooling water cavity from leaking at the positions of the first through hole 104 and the second through hole 203; by arranging a sealing ring in the second sealing groove 205a and making the second limiting platform 205 in abutting and cooperating connection with the second limiting groove 106b, the sealing ring in the second sealing groove 205a is extruded and sealed. By providing double seals at the first through hole 104 and the second through hole 203, it is further prevented that the coolant in the cooling water cavity leaks at the positions of the first through hole 104 and the second through hole 203; by arranging a sealing ring in the third sealing groove 206 and making the boss 106 in concave-convex cooperation with the cooling water tank 202, the boss 106 extrudes the third sealing ring to provide a pre-tightening force for the third sealing ring, so as to prevent the coolant in the cooling water cavity from leaking at the concave-convex cooperation position between the first half mold 1 and the second half mold 2.

[0037] In an exemplary embodiment of the present application, a bolt through hole 107 is provided on the first half mold 1, and a second limiting groove 106b is provided on the boss 106 around the bolt through hole 107.

[0038] In an exemplary embodiment of the present application, a third limiting platform 207 corresponding to the second limiting groove 106b is provided on the second half mold 2, the third limiting platform 207 is in abutting and cooperating connection with the second limiting groove 106b, and a bolt connection hole 207a is provided on the third limiting platform 207.

[0039] In an exemplary embodiment of the present application, a fourth sealing groove 207b is provided on the third limiting platform 207 around the bolt connection hole 207a.

[0040] In this embodiment, the bolt through-holes 107 are arranged within the cooling area, and the bolt connection holes 207a are correspondingly arranged within the cooling water tank 202. Therefore, an independent seal needs to be provided to prevent coolant leakage from the bolt connection holes 207a and the bolt through-holes 107. By providing a second limiting groove 106b on the first half mold 1 and a third limiting platform 207 correspondingly arranged on the second half mold 2 for the second limiting groove 106b, the third limiting platform 207 abuts and cooperates with the second limiting groove 106b, and by providing a sealing ring within the fourth sealing groove 207b on the third limiting platform 207, coolant leakage from the bolt connection holes 207a and the bolt through-holes 107 can be effectively prevented; the first half mold 1 and the second half mold 2 are connected by inserting bolts into the bolt through-holes 107 and threadedly connecting them with the bolt connection holes 207a, thereby realizing the connection between the first half mold 1 and the second half mold 2 to form the female mold, and furthermore, by tightening the connection with bolts, a pre-tightening force is provided for the sealing ring to achieve extrusion sealing.

[0044] In another exemplary embodiment, both the cooling flow field 101 and the cooling water tank 202 are subjected to surface nickel plating treatment, effectively reducing the problem of rust appearance in the cooling water cavity and improving the anti-corrosion ability of the cooling water cavity.

[0045] 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 main machine upper cover molding die. The cooling flow field 101 provided on the first half mold 1 and the cooling water tank 202 provided on the second half mold 2 cooperate to form a cooling water cavity. Since the cooling water tank 202 is correspondingly arranged in the area where the molding surface 201 is located, therefore, the cooling area of the formed cooling water cavity is basically the same as the molding area of the molding surface 201. The coolant is introduced into the cooling water cavity through the coolant inlet 102 provided on the first half mold 1. The coolant flows through the cooling water cavity and flows out of the cooling water cavity through the coolant outlet 103, thereby taking away heat. The glue is injected through the glue injection channel formed by the combination of the first through hole 104 and the second through hole 203, and the glue is injected into the molding surface 201 through the glue injection channel. Since the cooling area of the cooling water cavity formed in this application is basically the same as the molding area of the molding surface 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.
