Detailed Description
Fig. 1 is a schematic structural diagram of dropping-piece casting heads for investment casting according to the present invention, and fig. 2 is a schematic structural diagram of the cooperation of the casting protrusion and the blanking sleeve of dropping-piece casting heads for investment casting according to the present invention, as shown in fig. 1 and 2.
Referring to fig. 1 and 2, the invention provides an dropping casting head for investment casting, which comprises a casting body 1;
pouring body 1 outer wall is equipped with pouring arch 2 and falls a part of beating 3, is equipped with the sprue gate on every pouring arch 2, is equipped with main pouring channel in the pouring body 1, main pouring channel lateral wall is equipped with a plurality of pouring branch passageways that communicate with a plurality of sprue gates respectively, every pouring arch 2 outside all overlaps and is equipped with blanking cover 4, and blanking cover 4 is kept away from pouring body 1 side and is equipped with along a plurality of splint 41 of annular distribution, and two adjacent splint 41 interval arrangements, splint 41 keep away from blanking cover 4 end and lie in pouring arch 2 and keep away from pouring body side, and blanking cover 4 is close to pouring body 1 side and is equipped with reset spring 5, and reset spring 5 both ends are connected with pouring body 1 and blanking cover respectively.
In the concrete working process of the falling piece casting head for the investment casting of the embodiment, the casting body is arranged at the position of a casting hole of the mold, the main casting channel and the casting branch channel of the casting body are used for casting the mold cavity of the mold, the casting body and the casting are demolded after the casting is molded, the casting and the casting body are connected through the blanking sleeve, and the falling piece knocking part on the casting body is knocked, so that the relative displacement is generated between the vibration of the blanking sleeve and the casting, and the separation between the casting and the casting body is realized.
In this embodiment, the investment casting is with falling a casting head that casts, and the pouring body outer wall that provides is equipped with the pouring arch and falls a part of beating, is equipped with the sprue gate on every pouring arch, is equipped with main pouring channel in the pouring body, main pouring channel lateral wall is equipped with a plurality of pouring branch passageways that communicate with a plurality of sprue gates respectively, and every pouring arch outside all is equipped with the blanking cover, and the blanking cover is kept away from pouring body side and is equipped with a plurality of splint along annular distribution, and two adjacent splint interval arrangements, and the blanking cover is close to pouring body side and is equipped with reset spring, and the reset spring both ends are connected with pouring body and blanking cover respectively.
