Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.

An aluminum die-casting die for a street lamp power cover shell comprises an upper die base 10 and a lower die base 30, wherein the upper die base 10 is provided with an upper template 20, the lower die base 30 is provided with a lower template 40 corresponding to the upper template 20, the lower template 40 comprises an inner die body 41, slope concave cavities 42 are arranged on two sides of the inner die body 41, a main runner 43 is arranged at the high position of the slope concave cavity 42, and two branch runners 44 are arranged between the main runner 43 and the inner die body 41; the upper die plate 20 comprises an outer die body 21, and slope bosses 22 matched with the slope concave cavities 42 are arranged on two sides of the outer die body 21; when the die is closed, a cavity is formed between the outer die body 21 and the inner die body 41, the cavity is in the shape of a shell of a street lamp power supply cover, the slope boss 22 is completely buckled with the slope concave cavity 42, and no gap exists between the slope boss 22 and the slope concave cavity 42. The power cover housing 50 of the street lamp is embodied as a flat case body and the rear end of the case body is not provided with the rib 51. Because the slope cavity 42 is arranged on the two sides of the inner die body 41 at the lower die plate 40, after die-casting forming, production personnel can directly hold a product by using a hand buckle without prying the product out of the die by using an auxiliary tool, the operation is simple, the production efficiency is favorably improved, and the die cannot be damaged.

The lower die holder 30 also comprises a flow gathering round block 31, and the upper die holder 10 is provided with a liquid injection hole 11; when the mold is closed, the flow-gathering round block 31 is buckled into the liquid injection hole 11. The flow-gathering round block 31 is provided with a notch 311, one end of the main flow channel 43 is communicated with the branch flow channel 44, and the other end of the main flow channel 43 is communicated with the notch 311 of the flow-gathering block. During die casting, molten metal solution is poured into the liquid injection hole 11, flows from the liquid injection hole 11 to the flow gathering round block 31, flows into the main flow passage 43 along the notch 311 of the flow gathering round block 31, flows into the branch flow passage 44 from the main flow passage 43, and flows into the cavity between the outer die body 21 and the inner die body 41 along the branch flow passage 44, so that die casting molding is realized. Because the slope concave cavities 42 are arranged on the two sides of the inner die body 41 at the lower template 40, molten metal solution can flow into the die cavity between the outer die body 21 and the inner die body 41 along the slope concave cavities 42, so that the whole metal solidification process of die-casting molding is more reasonable, and the improvement of the yield is facilitated.

And a screw fixing hole is formed below the lower template 40, and a mold locking screw penetrates through a through hole of the lower die base 30 and is connected with the screw fixing hole. Because the screw fixing holes are arranged below the lower template 40, the upper surface of the lower template 40, which is contacted with the upper template 20, cannot affect the die-cast product due to the protrusion of a screw head and other factors.
