Description

TECHNICAL FIELD

[0003] Chinese patent CN218452583U discloses a one-mold double-out die for aluminum alloy die casting with a core exhaust mechanism, which comprises an upper punch and a bottom plate. Two stamping forming cavities are arranged between the upper punch and the bottom plate. The stamping forming cavities are formed by the upper forming surface arranged on the upper punch and the lower forming surface arranged on the bottom plate. The two stamping forming cavities between the upper punch and the bottom plate can form two aluminum alloy die castings at one time. The three die casting body forming grooves and the three die casting body forming protrusions cooperate to stamp and form three die casting body parts of the aluminum alloy die casting. The lower connecting plate forming part and the upper connecting plate forming part cooperate to stamp and form the connecting plate connecting the three die casting body parts. However, the device still has the following problems during use: By driving the upper punch to contact the bottom plate, a forming cavity is formed. However, when demolding is performed on a die casting with a complex outer shape, the die casting and the lower forming surface part of the bottom plate are likely to stick together.

[0014] In some embodiments, as shown in Figures 2-11 As a preferred embodiment of the present application, the driving assembly 51 includes a pneumatic push cylinder 511, a fixed rod 512, a roller 513 and a cross plate 514; the cross plate 514 is symmetrically fixed and installed at the right side of the front and rear ends of the static die plate 2; the pneumatic push cylinder 511 is symmetrically fixed and installed at the lower end of the front and rear sides of the cross plate 514; the output end of the pneumatic push cylinder 511 is fixedly installed with the fixed rod 512; the front end of the fixed rod 512 is rotatably installed with the roller 513; As shown in Figure 8 The movable plug-in assembly 52 includes an angle pin 521 and a connecting rod 522; the front and rear ends of the static die plate 2 and the end away from the two fixed main forming plates 21 are provided with sliding grooves 524; the angle pin 521 is limitingly and slidably connected with the sliding groove 524; the left end of the angle pin 521 is fixedly installed with the connecting rod 522; the front and rear sides of the connecting rod 522 are symmetrically provided with driving inclined surfaces 523; the roller 513 is rollingly connected with the driving inclined surface 523; The two driving inclined surfaces 523 are provided with low parts towards the side close to each other; the two driving inclined surfaces 523 are provided with high parts away from each other; As shown in Figure 11 The pushing assembly includes a push cylinder 31, a movable plate 32, a limiting plate 34 and a limiting clamping plate 35; the push cylinder 31 is fixedly installed at one end of the static die plate 2; the push cylinder 31 is connected with the end face forming assembly; As shown in Figure 8 and Figure 4As shown, the end face forming assembly includes a movable plate 32, a limiting plate 34 and a limiting clamping plate 35. The movable plate 32 is limitedly slidably connected to the right end of the static template 2; the output end of the push cylinder 31 is fixedly connected to the movable plate 32; the adjacent ends of the upper and lower movable plates 32 on the same side are each provided with a docking forming groove 33; The right end of the movable plate 32 is fixedly mounted with a limit plate 34; the right end of the static template 2 is fixedly mounted with a limit clamping plate 35; a limit slot 36 is defined in the limit clamping plate 35; the limit plate 34 is slidably connected to the limit slot 36; In the present invention, before starting the die-casting operation, the inner pneumatic push cylinder 511 works to drive the fixed rod 512 to move to the right, and the roller 513 moves to the right along with the fixed rod 512 until the roller 513 contacts the high part of the inner driving inclined surface 523, and pushes the connecting rod 522 to drive the angle pin 521 to move inward along the sliding groove 524 until the connecting rod 522 moves into the fixed main forming plate 21. At this time, the pneumatic push cylinder 511 drives the roller 513 to move to the maximum stroke, and at this time, the roller 513 is pressed against the low part of the inner driving inclined surface 523, preventing the driving inclined surface 523 from sliding outward; thereby achieving the preliminary positioning of the front and rear fixed main forming plates 21 and the static plate 2; and the fixed main forming plate 21 and the static plate 2 are fixed by bolts; Then the die-casting machine drives the movable platen 1 to move toward the static platen 2.

Subsequently, the multiple push cylinders 31 work to push the movable plates 32 to follow the limiting plates 34 and move along the limiting grooves 36 toward the fixed main forming plate 21 until the upper and lower movable plates 32 on the same side contact the upper and lower ends of the fixed main forming plate 21 on the same side; and at this time, the docking forming grooves 33 are aligned with the forming grooves 22. At this time, the forming protrusions 13, the forming grooves 22 and the docking forming grooves 33 together form a closed forming cavity. The injection mechanism of the die-casting machine is then inserted into the runner 11 and injects the molten metal into the runner 11 at a set speed and pressure. The diversion grooves 231 symmetrically provided on the front and rear sides of the docking protrusion 23 divert the molten metal into the front and rear molding protrusions 13 and molding grooves 22. The molding protrusions 13, molding grooves 22, and docking molding grooves 33 work together to finalize the casting contour. During the molding process, impurities and waste gas generated in the molding cavity will be discharged to the outside through the slag bag exhaust mechanism 4; After filling, the injection mechanism of the die casting machine keeps the pressure until the metal liquid in the molding cavity completely solidifies, then the multiple groups of push cylinders 31 work to separate the movable plate 32 from the fixed main molding plate 21, so that the butt joint molding groove 33 is separated from the molding groove 22, and the die casting machine works to separate the movable die plate 1 from the fixed die plate 2, and the injection mechanism of the die casting machine is synchronously separated from the movable die plate 1, so that the die casting remains in the molding convex groove 13 and is separated from the molding groove 22 and the butt joint molding groove 33, and finally the die casting is ejected from the molding convex groove 13 by the ejection mechanism of the die casting machine; When it is necessary to replace the fixed main molding plate 21, the outer pneumatic push cylinder 511 works to drive the fixed rod 512 to move to the right, so that the roller 513 is in contact with the high position part of the outer driving slope 523, then the inner pneumatic push cylinder 511 works to drive the inner roller 513 to separate from the inner driving slope 523, then the outer pneumatic push cylinder 511 continues to work to drive the roller 513 to move, so that the outer roller 513 moves from the high position part to the low position part of the outer driving slope 523, thereby extruding the connecting rod 522 to drive the angular pin 521 to move outwards along the sliding groove 524, so as to release the fixing of the fixed main molding plate 21 and the fixed die plate 2.
