Abstract

The invention relates to a vertical-type high-pressure casting die for an in-die automatic cutting casting system. A movable die comprises a movable die bottom plate, a movable die plate and a movable die core. The movable die core is arranged inside the movable die plate which is connected with the movable die bottom plate through a base plate. An ejector plate is arranged in a cavity surrounded by the movable die plate, the base plate and the movable die bottom plate. An ejector pin on the ejector plate penetrates through the movable die plate and the movable die core in sequence. A fixed die comprises a fixed die plate and a fixed die core. The fixed die core is arranged inside the fixed die plate. The fixed die core is matched with the movable die core to form a casting cavity. The casting system stretches into the casting cavity through the fixed die plate and the fixed die core. A material cutting mechanism comprises an oil cylinder, a material cutting rod and a material cutting guide sleeve. The material cutting guide sleeve is installed in the movable die core. The oil cylinder is installed inside the movable die bottom plate. A piston rod is installed on a piston inside the oil cylinder. The material cutting rod is fixed to the front end of the piston rod and stretches into the material cutting guide sleeve. The top end of the material cutting rod is opposite to the casting system. When molten metal is in a frozen but no strength state, the piston rod drives the material cutting rod to move, and a casting and the casting system are separated.

High-pressure casting is injected in airtight mold cavity by drift molten metal or semi-solid alloy, and high-pressure, make its solidification forming, finally obtain the method for product or blank.Having that liquid metal utilization rate is high, operation simplifies and the advantage such as steady quality, is a kind of energy-saving, metal-forming techniques with potential application foreground.Be successfully used to vapour, motorcycle manufacturing industry, aviation and war industry field, also widely apply in the industries such as instrument, hardware & tools, building.
When producing foundry goods with mould, molten metal injects the forming cavity in mould by running gate system, and after the metal freezing in chamber to be formed, foundry goods is taken out in die sinking, the foundry goods taken out from mould is also connected with running gate system, needs foundry goods and running gate system to cut off.This process need manually completes, and running gate system is excised from foundry goods and processes removal surface.This production model relates to a large amount of manpower consumptions and expenditure of time, and not only production efficiency is low, and production cost is high, and casting quality is affected by human factors comparatively large, less stable.
Under the production model that automated production degree is now more and more higher, be necessary to develop a kind ofly shorten the production cycle, mechanism that the indirect extrusion casting mould inside that reduces production cost excises running gate system automatically.
Summary of the invention
The object of the invention is the deficiency overcoming prior art existence, the vertical high-pressure casting mould automatically cutting off running gate system is provided in a kind of mould, be intended to shorten the production cycle, reduce production cost.
Object of the present invention is achieved through the following technical solutions:
Automatically the vertical high-pressure casting mould of running gate system is cut off in mould, feature: comprise dynamic model, cover half, material cutting mechanism and running gate system, described dynamic model comprises moving clamping plate, backing plate, liftout plate, thimble, moving platen and mavable module core, mavable module core is placed in moving platen, moving platen is connected with moving clamping plate by backing plate, liftout plate is placed in moving platen, in the chamber that backing plate and moving clamping plate surround, thimble on liftout plate is successively through the through hole on moving platen and mavable module core, described cover half comprises solid plate and fixed mold core, fixed mold core is placed in solid plate, solid plate is relative with moving platen, fixed mold core and mavable module core match to be formed and pour into a mould die cavity, running gate system stretches to cast die cavity through solid plate and fixed mold core, described material cutting mechanism comprises oil cylinder, blank bar and blank guide pin bushing, blank guide pin bushing is arranged in mavable module core, oil cylinder is arranged in moving clamping plate, in-oil cylinder piston is provided with piston rod, piston rod is vertically successively through the through hole on liftout plate and moving platen, blank bar is fixed on the front end of piston rod, blank bar stretches in blank guide pin bushing and matches with it, can along blank guide pin bushing rectilinear motion, the top of blank bar is relative with running gate system.
Further, automatically cut off the vertical high-pressure casting mould of running gate system in above-mentioned mould, wherein, the shape of described blank bar is cylindrical.
Further, automatically cut off the vertical high-pressure casting mould of running gate system in above-mentioned mould, wherein, described liftout plate is installed on and ejects on base plate, ejects base plate and is placed in the chamber that moving platen, backing plate and moving clamping plate surround.
The substantive distinguishing features that technical solution of the present invention is outstanding and significant progress are mainly reflected in:
Mould inscribe running gate system mechanism of the present invention, molten metal solidified but without state of strength time, piston rod moves downward, and drives the action of blank bar, is separated by foundry goods with running gate system.Compared to prior art, mould inscribe running gate system mechanism of the present invention, just can cut off running gate system at mould inside automatically at foundry goods cooling stage, make it to be separated with foundry goods, eliminate the operation of running gate system at the laggard row relax of die sinking, shorten the production cycle of foundry goods, reduce production cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1: cross section structure schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, automatically the vertical high-pressure casting mould of running gate system is cut off in mould, comprise dynamic model, cover half, material cutting mechanism and running gate system 11, described dynamic model comprises moving clamping plate 1, backing plate 2, eject base plate 3, liftout plate 4, thimble 5, moving platen 6 and mavable module core 7, mavable module core 7 is placed in moving platen 6, moving platen 6 is connected with moving clamping plate 1 by backing plate 2, eject base plate 3 and be placed in moving platen 6, in the chamber that backing plate 2 and moving clamping plate 1 surround, liftout plate 4 is installed on and ejects on base plate 3, thimble 5 on liftout plate 4 is successively through the through hole on moving platen 6 and the through hole on mavable module core 7, cover half comprises solid plate 8 and fixed mold core 9, fixed mold core 9 is placed in solid plate 8, solid plate 8 is relative with moving platen 6, fixed mold core 9 and mavable module core 7 match to be formed and pour into a mould die cavity, running gate system 11 stretches to cast die cavity through solid plate 8 and fixed mold core 9, material cutting mechanism comprises oil cylinder 12, blank bar 15 and blank guide pin bushing 16, the shape of blank bar 15 is cylindrical, blank guide pin bushing 16 is arranged in mavable module core 7, oil cylinder 12 is arranged in moving clamping plate 1, piston 13 in oil cylinder 12 is provided with piston rod 14, piston rod 14 is vertically successively through ejecting base plate 3, through hole on liftout plate 4 and moving platen 6, blank bar 15 is fixed on the front end of piston rod 14, blank bar 15 stretches in blank guide pin bushing 16 and matches with it, can along blank guide pin bushing 16 rectilinear motion, the top of blank bar 15 is relative with running gate system 11.
