As a preferred version of the present utility model, described mounting plate and described patrix are connected by screw, and described base is connected by pin with described counterdie.
The backboard die casting that the utility model provides is provided with at least one positioning spigot at the somatotype faying face place of upper die and lower die, the groove of positioning spigot is located on patrix, boss is located on counterdie, when upper die and lower die close, boss and fit depressions realize locating, and this cooperation becomes seam from the cooperation of original plane and coordinates, and effectively reduces the overlap of blank, ensure that casting pressure, and the dislocation of upper die and lower die can be prevented; Counterdie is provided with cast runner and the overflow runner of indent, and effectively can improve the quality of profiled member, die casting effect when die casting more good, production efficiency is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the backboard die casting that the utility model preferred embodiment one provides;
Fig. 2 is the top view of the counterdie that the utility model preferred embodiment one provides.
Be labeled as in figure:
1, patrix; 2, counterdie; 3, runner is poured into a mould; 4, overflow runner; 5, positioning spigot.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Preferred embodiment one:
Fig. 1 is the structural representation of the backboard die casting that this preferred embodiment one provides, this backboard die casting comprises patrix 1 and counterdie 2, patrix 1 is provided with the rectangular upper impression of body cross-section, counterdie 2 is provided with the rectangular lower impressions of body cross-section, upper impression and lower impressions form the die cavity of mould, and wherein, counterdie 2 is provided with cast runner 3 and the overflow runner 4 of indent, cast runner 3 extends to lower impressions, and overflow runner 4 distributes along the circumference of lower impressions; At least one positioning spigot 5 is provided with at the somatotype faying face place of patrix 1 and counterdie 2.
In the present embodiment, the groove of positioning spigot 5 is located on patrix 1, and the boss of positioning spigot 5 is located on counterdie 2, groove and boss suitable, positioning spigot 5 comprises four groups of these fit structures altogether.When patrix 1 and counterdie 2 close, boss and fit depressions realize locating, and this cooperation becomes seam from the cooperation of original plane and coordinates, and effectively reduces the overlap of blank, ensure that casting pressure, and can prevent the dislocation of upper die and lower die.
