The utility model provides a novel casting system of die casting die of large-scale 5G communication radiator part which characterized in that: it includes movable mould part, cover half part, the central zone of the orientation cover half part of movable mould part is provided with the movable mould core, the central zone of the orientation movable mould core of cover half part is provided with the cover half core, the combination forms the die cavity between movable mould core, the cover half core, a plurality of fin die cavity regions of having arranged, every are put towards the pan feeding mouth of die cavity region and are provided with water conservancy diversion muscle die cavity region towards the corresponding position of pan feeding mouth, water conservancy diversion muscle die cavity region is for the circular arc water conservancy diversion structure from the design terminal surface flaring of pan feeding mouth towards the fin gradually.
It is further characterized in that:
a main runner inlet and sub-runners are further arranged between the movable mold core and the fixed mold core, the main runner inlet is connected with inlets of the plurality of sub-runners, and outlets of the sub-runners are respectively communicated to a product feeding port and a flow guide rib cavity region;
the movable mould part and the fixed mould part are far away from one side of the main flow channel and are further spliced to form an exhaust part, and the exhaust part is convenient for gas exhaust of a die cavity formed by die casting.
After the invention is adopted, a flow guide rib cavity area is arranged at the corresponding position of each fin type cavity area facing the feeding port, the flow guide rib cavity area is an arc flow guide structure gradually expanding from the feeding port to the designed end face of the fin, so that the aluminum liquid is cast along the arc flow guide structure to form the fin, the flow guide rib is arranged at the edge of the fin in a preset shape, and the flow guide rib is partially removed after the processing is finished, so that the flow filling of the aluminum liquid is stable in the casting process, the reject ratio of a casting is reduced, the filling speed is reduced, and the service life of the mold is prolonged.

the device comprises a movable mould part 1, a fixed mould part 2, a movable mould core 3, a fixed mould core 4, a mould cavity 5, a fin mould cavity region 6, a flow guide rib mould cavity region 7, a main runner inlet 8, a sub-runner 9, a product feeding port 10, an exhaust part 11, a main runner part 12, a sub-runner part 13, a flow guide rib 14, a product 15 and fins 16.
Detailed Description
A novel casting system of a die-casting die for large-scale 5G communication radiator parts is shown in figures 1 and 2: the novel fin type water-cooling water heater comprises a movable mould part 1 and a fixed mould part 2, wherein a movable mould core 3 is arranged in a central area of the movable mould part 1 facing the fixed mould part 2, a fixed mould core 4 is arranged in a central area of the fixed mould part 2 facing the movable mould core 3, a mould cavity 5 is formed between the movable mould core 3 and the fixed mould core 4 in a combined mode, a plurality of fin type cavity areas 6 are distributed in the position of a feed inlet of the mould cavity 5, a diversion rib type cavity area 7 is arranged in the corresponding position of each fin type cavity area 6 facing the feed inlet, and the diversion rib type cavity area 7 is an arc diversion structure which is gradually flared from the feed inlet.
A main runner inlet 8 and sub-runners 9 are further arranged between the movable mold core 3 and the fixed mold core 4, the main runner inlet 8 is connected with inlets of the sub-runners 9, and outlets of the sub-runners 9 are respectively communicated to a product feeding port 10 and a flow guide rib cavity area 7;
an exhaust part 11 is further formed on one side of the movable mold part 1 and the fixed mold part 2 away from the main flow channel in a split mode, and the exhaust part 11 facilitates gas exhaust of a die cavity formed in the die-casting mode.
The main runner part 12, the sub-runner part 13, the flow guiding ribs 14 and the products 15 are formed after the cavity is filled by die casting, and the main runner part 12, the sub-runner part 13 and the flow guiding ribs 14 are separated from the products 15 through subsequent processing, so that the performance of the fin 16 is reliable.
The fins are directly and vertically arranged in front of the flow channel, so that the flow speed of the aluminum liquid is high, the forming is not good, and the cold isolation problem of the radiating fins is easy to occur due to the relatively thin fins.
The working principle is as follows: every fin type cavity area is provided with water conservancy diversion muscle die cavity area towards the corresponding position of pan feeding mouth, water conservancy diversion muscle die cavity area is from the pan feeding mouth towards the circular arc water conservancy diversion structure of the design terminal surface flaring of fin gradually for aluminium liquid forms the fin along circular arc water conservancy diversion structure die-casting, it sets up the water conservancy diversion muscle at the edge of fin preset shape, get rid of water conservancy diversion muscle part again after the processing is accomplished, make the mobile of die-casting in-process aluminium liquid fill steadily, reduce the foundry goods defective rate, and reduce filling speed, the life-span of mould has been improved.
