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.
Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a die casting die's runner structure, including sprue 1, first secondary runner 2, the spring beam 3, telescopic link 4, the flow liquid hole 5, the gim peg 6, casting 7, vice runner 8 of second and die cavity 9, the below of sprue 1 is provided with first secondary runner 2, and the side of sprue 1 is fixed with spring beam 3, the internal connection of spring beam 3 has telescopic link 4, and the one end of telescopic link 4 is fixed in the side of first secondary runner 2, flow liquid hole 5 has been seted up to the inboard of first secondary runner 2, and the inside of first secondary runner 2 is provided with vice runner 8 of second, flow liquid hole 5 has evenly been seted up to the inboard and the bottom surface of vice runner 8 of second, and the inside of flow liquid hole 5 is provided with gim peg 6, the below of sprue 1 is fixed with casting 7, and the inside of casting 7 is provided with die cavity 9.
The first auxiliary runner 2 is symmetrically arranged about the longitudinal center line of the main runner 1, the first auxiliary runner 2 and the main runner 1 form a rotation angle, the rotation angle range of the first auxiliary runner 2 and the rotation angle range of the main runner 1 are 0-90 degrees, the first auxiliary runner 2 is rotated to be vertical, the first auxiliary runner 2 is conveniently placed into a casting part 7, the situation that a pouring gate of the casting part 7 is too small is avoided, and the first auxiliary runner 2 which is horizontal cannot enter the casting part 7 is avoided.
The first auxiliary runner 2 and the second auxiliary runner 8 are in sliding connection and form a telescopic structure, when different casting parts 7 are subjected to die casting, the length of the casting part 7 and the position of a cavity 9 inside the casting part 7 are different, so that the length of the second auxiliary runner 8 extending out of the first auxiliary runner 2 can be adjusted according to the length of the casting part 7, after the first auxiliary runner 2 rotates inside the casting part 7, the length of the second auxiliary runner 8 is closer to that of the casting part 7, and when die casting liquid is poured, air generated inside the casting part 7 is reduced.
The inner side surfaces of the first auxiliary flow channel 2 and the second auxiliary flow channel 8 are uniformly provided with the liquid flow holes 5, the bottom surface of the second auxiliary flow channel 8 is uniformly provided with the liquid flow holes 5, the die-casting liquid enters the first auxiliary flow channel 2 and the second auxiliary flow channel 8 through the main flow channel 1, then flows into the casting part 7 through the liquid flow holes 5, the speed of the die-casting liquid entering the casting part 7 is reduced, and therefore the phenomenon that the die-casting liquid enters the casting part 7 too fast is avoided, bubbles are generated in the die-casting liquid, and the defect of finished products is caused.
The spring rod 3 and the telescopic rod 4 form a telescopic structure, and the two are arranged in a mirror image mode about the longitudinal center line of the main runner 1, when the first auxiliary runner 2 and the second auxiliary runner 8 enter the casting 7, the spring rod 3 pulls the telescopic rod 4 to contract, the telescopic rod 4 drives the first auxiliary runner 2 to rotate, so that the first auxiliary runner 2 and the second auxiliary runner 8 are horizontally horizontal, a dismounting and mounting structure is formed by conveniently filling the casting liquid hole 5 and the fixing bolt 6 into the casting 7, a cavity 9 is arranged below the liquid hole 5, the positions of the liquid hole 5 and the cavity 9 are mutually corresponding, the liquid hole 5 except the corresponding position above the cavity 9 is blocked by using the fixing bolt 6, the second auxiliary runner 8 is fixed, then the first auxiliary runner 2 and the second auxiliary runner 8 are placed into the casting 7 to be filled with the casting liquid, after the casting liquid flows into the first auxiliary runner 2 and the second auxiliary runner 8, will flow into the casting 7 through the liquid flow holes 5 above the cavity 9, so that the die-casting liquid will fill the cavity 9 at the bottom of the casting 7 first and flow to other places, thereby preventing the die-casting liquid from covering the whole cavity 9, causing air to remain at the bottom of the cavity 9, and the finished workpiece will have defects.
The working principle is as follows: when the runner structure of the die-casting die is used, firstly, the extending length of the second auxiliary runner 8 is adjusted according to the shape of a casting part 7, then, a liquid flow hole 5 corresponding to the casting part 7 in the casting part 7 above the casting part 7 is opened, and liquid flow holes 5 at other positions are blocked by using a fixing bolt 6, and meanwhile, the second auxiliary runner 8 is fixed;
placing the first auxiliary runner 2 and the second auxiliary runner 8 into a casting 7, pulling the telescopic rod 4 to move upwards by the spring rod 3 so as to enable the first auxiliary runner 2 to rotate, enabling the first auxiliary runner 2 to be horizontal, and injecting the casting solution into the device from the main runner 1;
after the die-casting liquid flows into the casting 7, the die-casting liquid flows down from the liquid flowing hole 5 above the cavity 9, so that the cavity 9 is prevented from being blocked by the die-casting liquid, air is reserved below the cavity 9, the main runner 1 is lifted upwards after the die-casting liquid is die-cast to a certain position, the bottom of the second auxiliary runner 8 is arranged at an injection port of the casting 7, the casting 7 is further die-cast, and the die-casting speed is low due to the fact that the casting 7 is die-cast through the liquid flowing hole 5, so that the problem that bubbles are generated inside the die-casting inside the casting 7 is solved, and the overall practicability is improved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
