[0008] Further, the lower side of the frame corresponding to each punch part is respectively provided with a blanking pipe for guiding the piston casting, and the lower side of each blanking pipe is respectively provided with a discharge chute.
[0009] Further, the punch driving device is a pneumatic cylinder.
[0010] The utility model discloses above technical scheme, the position of the punch, the cinder ladle stopper and the runner stopper can be adjusted, so the edge of different model size piston casting can be adapted. BRIEF DESCRIPTION OF DRAWINGS
[0011] The utility model will be explained in further detail below in combination with the drawings and specific embodiment:
[0012] Figure 1 It is the perspective view of the utility model;
[0013] Figure 2 It is the front view of the utility model;
[0014] Figure 3 It is the side view of the utility model;
[0015] Figure 4 It is the perspective view of the piston (4 holes) of casting. SPECIFIC EMBODIMENT
[0016] As shown in Figures 1-4 The utility model discloses a kind of multi-model general die-casting piston gate edge cutting mould, including rack 1, cutting driver 2, punch fixed plate 3 and positioning strip 4, cutting driver 2 is fixed at the top of rack 1, the bottom of the output end of cutting driver 2 is fixedly connected with the top of punch fixed plate 3, cutting driver 2 drives punch fixed plate 3 to do lifting motion.Punch fixed plate 3 is located directly below in positioning strip 4, and a plurality of punchings 5 are fixed on positioning strip 4, and punch fixed plate 3 bottom corresponds each punching 5 respectively fixed with punch 6, cinder ladle stopper 7 and runner stopper 8;Corresponding punch 6, cinder ladle stopper 7 and runner stopper 8 are provided with long strip-shaped connecting hole 14 on punch fixed plate 3, and each punch 6, cinder ladle stopper 7 and runner stopper 8 are locked and fixed on the bottom of punch fixed plate 3 by corresponding bolt through corresponding connecting hole 14 respectively.Punching 5 is respectively connected with spacing adjustment block 9 on positioning strip 4, and each punching 5 is fixedly connected on corresponding spacing adjustment block 9, and long strip-shaped connecting hole 15 is also respectively provided on positioning strip 4 corresponding each spacing adjustment block 9, and each spacing adjustment block 9 is locked and fixed on positioning strip 4 by corresponding bolt through corresponding connecting hole 15 respectively.
[0017] The both sides of rack 1 are respectively fixed with guide column 10 arranged along vertical direction, and the both sides of punch fixed plate 3 are respectively slidably connected with corresponding side guide column 10 through guide sleeve.
[0018] The bottom of positioning strip 4 is provided with waste chute 13 for receiving and discharging casting slag ladle and runner.
[0019] The punching driver 2 is a cylinder.
[0020] The utility model works: the mechanical arm clamps the whole mold piston casting and places in the punch piece 5, the punch driver 2 drives the punch 6 connected on the punch fixed plate 3 to go down and press the piston casting, and the sprue is cut off under the interaction force of the cutting edge of the punch piece 5, the piston casting falls into the discharge chute 12 from the blanking pipe 11 respectively, and then the piston casting is sent into the corresponding goods frame through the conveying belt respectively, and the slag pocket and the runner of the piston casting fall into the waste chute 13 and then slide into the waste frame under the blocking of the slag pocket stopper 7 and the runner stopper 8.
