Detailed Description
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The technical solution of the present invention will be described more clearly and completely with reference to the accompanying drawings, in which embodiments of the invention are shown and described. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The aluminum alloy wheel water cooling mold according to the embodiment of the present invention is described below with reference to fig. 1 to 4 in combination with the embodiment.
The utility model discloses an aluminum alloy wheel water cooling mold, including the top mould, the top mould includes through 6 last top moulds 5 and lower top moulds 8 of connecting of bolt, goes up and sets up flutedly on the top mould 5, has set gradually water-cooling piece 2 and the water-cooling briquetting 4 of butt on water-cooling piece 2 in the recess, and water-cooling piece 2 encloses with the grooved underside of last top mould 5 and closes and form cooling water course 1. The parting line 9 of the upper top die 5 and the lower top die 8 is arranged 5-15mm below the highest point of the inner rim of the wheel. The upper top die 5 protrudes 80.2-0.5 mm from the lower top die on the left side of the parting line 9. The length of the parting line is 5-10mm, and the contact surfaces of the upper top die 5 and the lower top die 8 corresponding to the parting line 9 are tightly matched. A gap is arranged between the mounting vertical surfaces of the upper top die 5 and the lower top die 8. Grooves are processed on two sides of the matching part of the upper top die 5 and the water cooling block 2. The matching surface of the water cooling block 2 and the water cooling pressing block 4 is provided with a sawtooth-shaped groove.
In some embodiments, according to the specific features of the wheel type, the upper and lower top mold parting lines 9 are formed 5-15mm below the highest point of the inner rim product line, and since the cooling water passage 1 is located in the upper top mold 5, the parting line 9 is located below the highest point of the inner rim, which is located in the upper top mold 5, the cooling water passage 1 in the upper top mold 5 can sufficiently cool the inner rim.
At the parting position of the upper top die 5 and the lower top die 8, the cooling conduction of cooling water is reduced through the parting surface, the upper top die 5 shrinks greatly relative to the lower top die 8 due to the cooling of a water channel, and in order to prevent the wheel from being difficult to demould or being scratched, 0.2-0.5mm of dislocation is reserved at the position A encircled by an ellipse in the figure 3, and a margin is reserved for the shrinkage of the upper top die 5.
As shown in fig. 3, a mating surface of 5-10mm is reserved at the oval-circled mating position B of the upper top die 5 and the lower top die 8, and the upper top die 5 and the lower top die 8 are tightly mated at the mating surface, so that aluminum leakage is prevented on one hand, and the influence of cooling of the upper top die on the lower top die is reduced on the other hand.
As shown in fig. 3, a clearance of 0.5mm is reserved at the mating position C, D where the upper top die 5 and the lower top die 8 are oval, and the clearance mating of the upper top die 5 and the lower top die 8 reduces the influence of the cooling of the upper top die 5 on the lower top die 8.
As shown in fig. 4, grooves of 0.2mm are formed on both sides of the matching portion of the upper top die 5 and the water cooling block 2, so that the diffusion of cooling to both sides of the water channel is reduced, and the cooling of the inner rim is ensured by having better 'directionality'.
As shown in fig. 4, the matching surfaces of the water-cooling block 2 and the water-cooling pressing block 4 are provided with saw tooth grooves which are 1mm deep and are uniformly distributed, so that the severe shrinkage and expansion of the water-cooling pressing block 4 in the production cycle process are reduced while the transmission of water channel cooling to the water-cooling pressing block 4 is reduced, the reliability of water channel craters is improved, and the service life of a die is ensured.
