For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0025] In one embodiment of the present application, as Figures 1-6As shown, a notebook C-face die-casting die is provided, comprising a die body 1, a die-casting runner 2 is arranged in the die body 1, the die-casting runner 2 comprises a biscuit cavity 21, a main runner 22, a cross runner 23, a flat gate 24 and a die-casting cavity 3, the biscuit cavity 21 is communicated with the main runner 22, the other end of the main runner 22 is communicated with the middle part of the cross runner 23, the flat gate 24 is several in number and is uniformly distributed on the side of the cross runner 23 away from the main runner 22, the other end of each flat gate 24 is communicated with the head end of the die-casting cavity 3, the die-casting cavity 3 comprises a main cavity 31 and a keyboard part 32 and a touchpad part 33 arranged in the main cavity 31, the touchpad part 33 is covered with a raised part 331, and a strip-shaped boss 332 is arranged in the raised part 331.

[0026] Further, the height of the raised part 331 is 0.1mm, the number of the strip-shaped boss 332 is at least two, the height of the strip-shaped boss 332 is 0.2mm, and the strip-shaped boss 332 extends from the head end to the tail end of the touchpad part 33. Specifically, the metal flow has a high temperature and good fluidity when it is in the biscuit cavity 21, and gradually fills the die-casting cavity 3 after passing through the main runner 22, the cross runner 23 and the flat gate 24, but the temperature of the metal flow decreases and the fluidity decreases when the metal flow reaches the tail end of the die-casting cavity 3. By arranging the raised part 331, the metal flow can be guided, the fluidity of the metal flow is increased, the metal flow in the touchpad part 33 can be guided by arranging the strip-shaped boss 332, the fluidity of the metal flow is further increased, the fluidity of the metal flow between two adjacent strip-shaped bosses 332 is further improved under the guiding action of the strip-shaped bosses 332, and the fluidity of the metal flow is further increased, and the cold material problem of the metal flow is improved.

[0027] Further, the first end of the die casting cavity 3 is provided with a rotating shaft seat part 34, the rotating shaft seat part 34 is connected with the first end of the keyboard part 32, the rotating shaft seat part 34 includes two split bodies 341 symmetrically arranged at the two sides of the first end of the die casting cavity 3 and a groove position 342 located at the middle part of the two split bodies 341, the middle part of the keyboard part 32 is covered with a thickened part 321, the thickness of the thickened part 321 is 0.1mm, the groove position 342 is recessed towards the keyboard part 32, and the groove position 342 is in communication with a plurality of the flat sprues 24. Specifically, the metal flow has a higher temperature and better flowability when it is in the cake cavity 21, flows through the main runner 22, the cross runner 23, and then through the flat sprue 24 into the die casting cavity 3, and gradually fills the die casting cavity 3, after the product is die-cast and formed, the groove position 342 of the rotating shaft seat part 34 is the shrinkage structure position of the product, and the shrinkage causes the die-cast product to be unqualified, the thickened part 321 arranged at the middle part of the keyboard part 32 can form a flow guiding effect on the metal flow, so that the metal flow flows more to the two split bodies 341 of the rotating shaft seat part 34 and the touch plate part 33, and the sand hole phenomenon of the product is improved.

[0028] Working principle: the metal flow in the cake cavity 21 flows through the main runner 22, the cross runner 23, and then through the flat sprue 24 into the first end of the die casting cavity 3 and gradually flows to the end, when the metal flow reaches the touch plate part 33 at the end of the die casting cavity 3, the heat is reduced to cause the flowability to be weakened, the thickened effect of the increased part 331 and the strip-shaped boss 332 on the touch plate part 33 realizes the improvement of the flowability of the metal flow, and the weakening of the flowability of the metal flow due to the heat loss when the metal flow flows to the end of the die casting cavity 3 is improved, so that the metal flow can better fill the end of the mold.

[0029] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
