A fully automatic control zinc alloy die-casting forming device

Abstract

This invention discloses a fully automatic zinc alloy die-casting forming device, belonging to the field of zinc alloy die-casting forming technology. The invention utilizes a movable push plate, an L-shaped slide, a pushing protrusion, a rotating crankshaft, a striking column, and a swaying frame. After die-casting, the workpiece falls freely into the swaying frame below, completing fully automatic demolding. Simultaneously, a dual-shaft motor drives the main drive wheel to rotate, while a connecting strip pulls the concave connecting frame to slide, causing the swaying slider to slide back and forth along the mounting column in the rectangular through-slot of the fixed side plate. The swaying spring extends and retracts with the sliding of the swaying slider, providing both reset power and amplifying the swaying amplitude of the swaying frame. Four swaying sliders synchronously pull the swaying frame to perform high-frequency reciprocating swaying between the two fixed side plates. The formed workpiece, falling into the swaying frame, moves towards the frame's discharge port under the action of swaying inertia and is finally quickly swayed out of the device, thereby improving the processing efficiency of zinc alloy die-casting.

Description

Technical Field

[0001] This invention relates to the field of zinc alloy die casting technology, specifically to a fully automated zinc alloy die casting apparatus. Background Technology

[0002] Zinc alloy die castings occupy a key position in modern industrial manufacturing systems due to their excellent casting fluidity, uniform forming accuracy, good mechanical strength, stable dimensional consistency, and outstanding surface finish. They are widely used in many high-end manufacturing fields such as automotive precision structural parts, electronic housings and connectors, hardware decorative accessories, smart home components, security equipment, and power tools. They are one of the core materials for achieving lightweight, precision, and mass production. With the continuous advancement of Industry 4.0, the deep popularization of intelligent manufacturing technology, and the urgent needs of downstream industries for high-efficiency, high-consistency, low-cost, and low-manpower production modes, zinc alloy die casting equipment is upgrading towards full-process automation, high-precision control, rapid mold change, and continuous and stable operation.

[0003] Existing fully automated zinc alloy die casting forming equipment relies on manual removal or simple ejection mechanisms to demold after the workpiece is formed. Zinc alloy workpieces tend to have strong adhesion to the mold cavity, and simple ejection can easily cause workpiece tearing, deformation, or even sticking to the mold, resulting in a low demolding success rate. In addition, the mold opening and closing is mostly linear motion, and it is difficult to use gravity to make the workpiece fall off the mold surface when it is detached from the mold surface, causing the workpiece to get stuck inside the mold cavity.

[0004] Based on this, the present invention designs a fully automated zinc alloy die-casting forming device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automated zinc alloy die casting forming device to solve the problems mentioned in the background art. In existing fully automated zinc alloy die casting forming devices, after the workpiece is formed, demolding is mostly achieved by manual removal or simple ejection mechanism. Zinc alloy workpieces tend to have strong adsorption forces with the mold cavity. Simple ejection can easily cause workpiece tearing, deformation, or even sticking to the mold, resulting in a low demolding success rate. In addition, the mold opening and closing is mostly linear motion, and when the workpiece is separated from the mold surface, it is difficult to use gravity to make the workpiece fall off the mold surface, resulting in the workpiece getting stuck inside the mold cavity.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fully automatic zinc alloy die-casting forming device includes two fixed side plates. Movable push plates are slidably mounted on the top of the two fixed side plates on their opposite sides. A mounting and fixing mechanism is symmetrically arranged between the two fixed side plates. Multiple punches and dies are respectively arranged between the two mounting and fixing mechanisms, with the punches and dies facing each other in pairs. A striking mechanism is respectively provided on the top of the two fixed side plates on both sides of the two mounting and fixing mechanisms. A dual-shaft motor is fixedly mounted on one side of the bottom between the two fixed side plates. A transmission mechanism is respectively provided on the opposite sides of the two fixed side plates. A wobbling discharge mechanism is provided at the bottom between the two fixed side plates.

[0008] As a further embodiment of the present invention, a rectangular through groove is symmetrically provided through the top of the side of the fixed side plate, and four T-shaped limiting blocks are fixedly installed on the top of the outer side of the fixed side plate, with two T-shaped limiting blocks forming a group. The two groups of T-shaped limiting blocks are symmetrically fixedly installed on both sides of the top of the side of the fixed side plate. A rectangular mounting groove is provided at the center of the top of the outer side of the fixed side plate. A limiting slide groove one and a limiting slide groove two are symmetrically provided through the top of the two sides of the fixed side plate located at the rectangular mounting groove. The limiting slide groove two is located at the bottom of the limiting slide groove one. The limiting slide groove two consists of a horizontal through groove and an inclined through groove, and one end of the horizontal through groove is connected to the bottom end of the inclined through groove.

[0009] As a further embodiment of the present invention, the movable push plate slides close to the top of the outer side of the fixed side plate. An electric push rod is fixedly installed inside the rectangular mounting groove. A pushing block is fixedly connected to the telescopic end of the bottom of the electric push rod, and the pushing block is fixedly connected to the bottom of the movable push plate near the fixed side plate. Rectangular limiting grooves are symmetrically provided on both sides of the movable push plate, and the rectangular limiting grooves are slidably connected to the surface of the T-shaped limiting block. An L-shaped slide groove and a pushing slide groove are provided on both sides of the movable push plate located on the electric push rod. The L-shaped slide groove corresponds to the first limiting slide groove, and the pushing slide groove corresponds to the second limiting slide groove. The L-shaped slide groove is composed of an inclined through groove and a vertical through groove, and the bottom end of the vertical through groove is connected to the top end of the inclined through groove. The pushing slide groove is composed of two inclined through grooves, and the two inclined through grooves are connected.

[0010] As a further embodiment of the present invention, the mounting and fixing mechanism includes a mounting frame, which is tightly fitted between two fixed side plates. Pushing protrusions are symmetrically fixedly mounted on both sides of the mounting and fixing mechanism, and the pushing protrusions pass through the position where the limiting slide groove one and the L-shaped slide groove overlap or the position where the limiting slide groove two and the pushing slide groove overlap. Three mold mounting slots are equidistantly provided on the side of the mounting frame. Mounting slide rods are symmetrically fixedly mounted on the top and bottom of the mounting frame at the mold mounting slots, and movable sliders are slidably mounted on the surface of the mounting slide rods. A fixed spring is sleeved on the surface of the mounting slide rod on the side of the movable slider. A fixing clip is fixedly mounted between the two movable sliders, and a fixing hook is fixedly connected to both ends of the fixing clip. Fixed plates are rotatably mounted on the four corners of the mounting frame at the mold mounting slots through pins, and the fixed plates are correspondingly engaged with the fixed hooks.

[0011] As a further embodiment of the present invention, the shapes of the convex mold and the concave mold correspond to each other. An L-shaped card holder 1 is fixedly installed at each of the four corners of the convex mold away from the concave mold, and the L-shaped card holder 1 is snapped onto the surface of the fixed card strip. An L-shaped card holder 2 is fixedly installed at each of the four corners of the concave mold away from the convex mold, and the L-shaped card holder 2 is snapped onto the surface of the fixed card strip.

[0012] As a further embodiment of the present invention, the striking mechanism includes a fixed plate, and the two ends of the fixed plate are fixedly connected to the top of the opposite side of two fixed side plates. A plurality of striking columns are slidably installed through the fixed plate, and two striking columns form a group. One end of each group of striking columns passes through the fixed plate and is fixedly installed with a pusher frame. A striking block is fixedly installed at the end of the striking column away from the pusher frame, and the striking block is in close contact with the side of the punch and die near the L-shaped bracket one and L-shaped bracket two. A striking spring is sleeved on the surface of the striking column between the fixed plate and the striking block. A rotating crankshaft is rotatably installed between the two fixed side plates located on one side of the fixed plate through a bearing, and the rotating crankshaft is composed of a plurality of cranks, which are slidably connected inside the pusher frame.

[0013] As a further embodiment of the present invention, the transmission mechanism includes a main transmission wheel, which is fixedly connected to the output shafts at both ends of the dual-output-shaft motor. A transmission belt is sleeved on the surface of the main transmission wheel. The two rotating crankshafts are respectively fixedly connected to a linkage transmission wheel or a linkage transmission wheel by passing through the fixed side plate. The top of the inner ring of the transmission belt is sleeved on the surface of the linkage transmission wheel. The surfaces of the linkage transmission wheel and the linkage transmission wheel are sleeved with a transmission belt, and the transmission belt and the transmission belt are arranged perpendicularly.

[0014] As a further embodiment of the present invention, the wobbling discharge mechanism includes four mounting columns, which are respectively fixedly connected inside a rectangular through groove. A wobbling slider is slidably mounted through the surface of the mounting column, and the wobbling slider slides close to the inner wall of the rectangular through groove. A wobbling spring is sleeved on both sides of the mounting column located on the wobbling slider. A concave connecting frame is fixedly installed between two wobbling sliders on the same side. A connecting strip is rotatably mounted at the center of one side of the concave connecting frame via a protrusion, and the end of the connecting strip away from the concave connecting frame is rotatably connected to the edge of the main drive wheel via the protrusion. A wobbling frame is fixedly installed between the four wobbling sliders.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the setting of a movable push plate, L-shaped slide groove, pushing protrusion, rotating crankshaft, striking column, and shaking frame, after die casting, controls the extension of the electric push rod. Its telescopic end drives the pushing block to move downward. The pushing block synchronously pulls the movable push plate to slide stably along the surface of two sets of T-shaped limiting blocks on the top outer side of the fixed side plate. The L-shaped slide groove and pushing slide groove on both sides of the movable push plate are aligned and connected with the limiting slide groove one and limiting slide groove two of the fixed side plate, respectively. This causes the pushing protrusion to slide synchronously in the aligned slide groove. Due to the tilting of the slide groove and the guiding effect of the horizontal structure, the two mounting frames deflect in a direction away from each other between the two fixed side plates. This causes the convex and concave molds mounted on the mounting frames to tilt synchronously with the frames. After the convex and concave molds are closely aligned with the striking block, the dual-output shaft motor is started. Its output shafts at both ends drive the transmission mechanism to move, causing the two rotating crankshafts to rotate synchronously. When the rotating crankshafts rotate, their cranks slide inside the pushing frame, controlling the pushing frame to synchronously pull the striking block. The striking column slides back and forth along the fixed plate, and the striking block at the end of the striking column moves in an integrated manner, performing high-frequency reciprocating striking on the surfaces of the closely attached punch and die. The vibration force generated by the high-frequency striking can quickly eliminate the adsorption force between the workpiece and the forming surface of the die, causing the die-casting workpiece that was originally adsorbed on the surface of the punch and die to detach from the die and fall freely into the shaking frame below, completing the fully automatic demolding. While the dual-shaft motor drives the main drive wheel to rotate, the connecting strip pulls the concave connecting frame to slide, causing the shaking slider to slide back and forth along the mounting column in the rectangular through groove of the fixed side plate. The shaking spring moves with the sliding of the shaking slider, providing the shaking slider with the reset power and amplifying the shaking amplitude of the shaking frame. The four shaking sliders synchronously pull the shaking frame to perform high-frequency reciprocating shaking between the two fixed side plates. The formed workpiece that falls into the shaking frame moves towards the discharge port of the frame under the action of shaking inertia and finally shakes out of the device quickly, thereby improving the processing efficiency of zinc alloy die casting. 2. This invention, by setting up a convex mold, a concave mold, a fixing spring, and fixing clips, allows for the following installation process: First, the convex and concave molds are inserted into the corresponding mold mounting slots of the mounting frame. Simultaneously, two fixing clips on the mounting frame are pushed and pressed. The fixing clips cause the sliding blocks at both ends to slide inward along the mounting slide rod, simultaneously pressing the fixing springs on the surface of the mounting slide rod. This causes the fixing springs to elastically contract and store elastic potential energy, continuously pushing the fixing clips until the backs of the convex and concave molds are completely pressed against the fixing clips, and the L-shaped clips of the convex mold and the L-shaped clips of the concave mold are aligned with the fixing clips. With precise alignment, the fixing clip is released, and the fixing spring releases its elastic potential energy and generates a rebound thrust, pushing the moving slider to slide outward along the mounting rod. The moving slider simultaneously drives the fixing clip to reset, allowing the fixing clip to precisely engage with L-shaped bracket one and L-shaped bracket two, initially limiting the punch and die inside the mold mounting slot to prevent lateral displacement of the mold in subsequent operations. Then, the fixing plate is rotated to engage with the fixing hook, providing secondary reinforcement and limiting of the fixing clip to prevent it from loosening due to vibration and extrusion forces during die casting, thus facilitating the disassembly and installation of the punch and die.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-10 The present invention provides a technical solution:

[0031] A fully automatic zinc alloy die-casting forming device includes two fixed side plates 1. Movable push plates 2 are slidably mounted on the top of the two fixed side plates 1 on their opposite sides. A mounting and fixing mechanism 3 is symmetrically arranged between the two fixed side plates 1. Multiple punches 4 and concave dies 5 are respectively arranged between the two mounting and fixing mechanisms 3, with the punches 4 and concave dies 5 facing each other in pairs. A striking mechanism 6 is respectively provided on the top of the two fixed side plates 1 on both sides of the two mounting and fixing mechanisms 3. A dual-shaft motor 7 is fixedly mounted on one side of the bottom between the two fixed side plates 1. A transmission mechanism 8 is respectively provided on the opposite sides of the two fixed side plates 1. A wobbling discharge mechanism 9 is provided at the bottom between the two fixed side plates 1.

[0032] During operation, the corresponding punch 4 and die 5 are selected according to the processing requirements. The punch 4 and die 5 are fixed relatively inside the corresponding mounting and fixing mechanism 3. The moving push plate 2 is controlled to slide on the side of the fixed side plate 1, driving the mounting and fixing mechanism 3 to slide between the two fixed side plates 1. After the zinc alloy is die-cast inside the punch 4 and die 5, the moving push plate 2 is controlled to slide down on the side of the fixed side plate 1, causing the two mounting and fixing mechanisms 3 to drive the punch 4 and die 5 to deflect away from each other between the two fixed side plates 1 until... The sides of the punch 4 and the die 5 are in contact with the striking mechanism 6. The dual-shaft motor 7 is started and driven by the transmission mechanism 8 to move the striking mechanism 6 between the two fixed side plates 1, reciprocatingly striking the punch 4 and the die 5, causing the workpieces adsorbed on the surface of the punch 4 and the die 5 to fall into the shaking discharge mechanism 9. As the dual-shaft motor 7 drives the transmission mechanism 8 to work, the shaking discharge mechanism 9 shakes between the two fixed side plates 1, gradually shaking the workpieces that have fallen into the shaking discharge mechanism 9 to detach and discharge them.

[0033] As a further embodiment of the present invention, a rectangular through groove 101 is symmetrically provided through the top of the side of the fixed side plate 1. Four T-shaped limiting blocks 102 are fixedly installed on the outside of the fixed side plate 1 above the rectangular through groove 101, and two T-shaped limiting blocks 102 form a group. The two groups of T-shaped limiting blocks 102 are symmetrically fixedly installed on both sides of the top of the side of the fixed side plate 1. A rectangular mounting groove 103 is provided on the outside of the fixed side plate 1 at the center of the two groups of T-shaped limiting blocks 102. An electric push rod 201 is fixedly installed inside the rectangular mounting groove 103. A push block 202 is fixedly connected to the telescopic end of the bottom of the electric push rod 201. The movable push plate 2 slides close to the top of the outside of the fixed side plate 1, and the push block 202 is fixedly connected to the bottom of the movable push plate 2 on the side close to the fixed side plate 1. Rectangular limiting grooves 203 are symmetrically provided through the sides of the movable push plate 2, and the rectangular limiting grooves 203 are slidably connected to the surface of the T-shaped limiting blocks 102.

[0034] When the device is working, the electric push rod 201 serves as the power source for the movable push plate 2. Its telescopic end is fixedly connected to the push block 202. When the electric push rod 201 extends or retracts, it controls the push block 202 to drive the movable push plate 2 to slide against the surface of the fixed side plate 1. The two sets of T-shaped limit blocks 102 on the top outer side of the fixed side plate 1 provide precise limit for the sliding of the movable push plate 2. The rectangular limit grooves 203 on both sides of the movable push plate 2 are slidably connected to the surface of the T-shaped limit blocks 102, so that the movable push plate 2 can slide smoothly along the top outer side of the fixed side plate 1, avoiding problems such as offset and jamming during the sliding process.

[0035] As a further embodiment of the present invention, the fixed side plate 1 is symmetrically provided with a limiting slide groove 104 and a limiting slide groove 205 on both sides of the rectangular mounting groove 103. The limiting slide groove 205 is located at the bottom of the limiting slide groove 104 and is composed of a horizontal through groove and an inclined through groove, with one end of the horizontal through groove connected to the bottom end of the inclined through groove. The movable push plate 2 is provided with an L-shaped slide groove 204 and a pushing slide groove 205 on both sides of the electric push rod 201. The L-shaped slide groove 204 corresponds to the limiting slide groove 104, and the pushing slide groove 205 corresponds to the limiting slide groove 205. The L-shaped slide groove 204 is composed of an inclined through groove and a vertical through groove, with the bottom end of the vertical through groove connected to the top end of the inclined through groove. The pushing slide groove 205 is composed of two inclined through grooves connected to each other.

[0036] The mounting and fixing mechanism 3 includes a mounting frame 301, which is attached to the space between two fixed side plates 1. Pushing protrusions 302 are symmetrically fixed on both sides of the mounting and fixing mechanism 3, and the pushing protrusions 302 pass through the overlapping positions of the limiting slide groove 104 and the L-shaped slide groove 204, and the overlapping positions of the limiting slide groove 205 and the pushing slide groove 205.

[0037] During operation, the limiting slide groove 104 and limiting slide groove 205 on the fixed side plate 1 correspond to the L-shaped slide groove 204 and pushing slide groove 205 on the movable push plate 2. When the movable push plate 2 slides on the surface of the fixed side plate 1, the limiting slide groove 104 and limiting slide groove 205 on the fixed side plate 1 coincide with the L-shaped slide groove 204 and pushing slide groove 205 on the movable push plate 2. The pushing protrusions 302 on both sides of the mounting frame 301 pass through the overlapping positions of the corresponding slide grooves, forming a slide groove linkage structure. The irregular structure of each slide groove provides directional guidance for the sliding of the pushing protrusions 302. When the movable push plate 2 is driven by the electric push rod 201... When the moving pusher slides along the fixed side plate 1, it drives the pusher 302 to slide in the overlapping groove, thereby pulling the mounting frame 301 to make directional deflection, approach or move away between the two fixed side plates 1, realizing the position adjustment of the mounting frame 301, providing structural support for the mold closing die casting and mold opening demolding, until the pusher 302 moves to the inflection point position inside the limiting groove 104 and limiting groove 105 on the fixed side plate 1 and the L-shaped groove 204 and pushing groove 205 on the moving push plate 2, the moving push plate 2 continues to slide, so that the mounting frame 301 gradually deflects and tilts between the two fixed side plates 1.

[0038] As a further embodiment of the present invention, the mounting frame 301 is provided with three mold mounting slots 303 equidistantly through its side. The mounting frame 301 is symmetrically fixedly mounted with mounting slide rods 304 at the top and bottom of the mold mounting slots 303, and a movable slider 305 is slidably mounted through the surface of the mounting slide rod 304. A fixing spring 306 is sleeved on the surface of the mounting slide rod 304 on one side of the movable slider 305. A fixing clip 307 is fixedly mounted between the two movable sliders 305, and a fixing hook 308 is fixedly connected to both ends of the fixing clip 307. Fixed plates 309 are rotatably mounted on the four corners of the mounting frame 301 at the mold mounting slots 303 via pins, and the slots on the fixed plates 309 are correspondingly engaged with the fixing hooks 308.

[0039] The shapes of the punch mold 4 and the die mold 5 correspond to each other. L-shaped brackets 401 are fixedly installed at the four corners of the side of the punch mold 4 away from the die mold 5, and the L-shaped brackets 401 are snapped onto the surface of the fixing strip 307. L-shaped brackets 501 are fixedly installed at the four corners of the side of the die mold 5 away from the punch mold 4, and the L-shaped brackets 501 are snapped onto the surface of the fixing strip 307.

[0040] During operation, the mold mounting slot 303 on the mounting frame 301 provides a standardized installation and positioning space for the punch mold 4 and the die mold 5, ensuring precise alignment of the forming surfaces after insertion. Before installation, pushing the fixing clip 307 causes the sliding blocks 305 at both ends to slide along the mounting slide rod 304, while simultaneously compressing the fixing spring 306 to store energy. After inserting the punch mold 4 and the die mold 5 into the mold mounting slot 303 respectively, the fixing clip 307 is released, and the fixing spring 306 returns to its original position. The movable slider 305 is pushed back to its original position, causing the fixed clip 307 to engage with the L-shaped clip 401 and L-shaped clip 501, completing the initial positioning of the mold. Then, the fixed plates 309 at the four corners of the mold mounting slot 303 are rotated to engage with the fixed hooks 308 at both ends of the fixed clip 307, providing secondary reinforcement to the fixed clip 307. During the die-casting process, this double-fixed structure effectively counteracts the extrusion and vibration forces, preventing the punch 4 and die 5 from shifting or loosening, thus ensuring the accuracy of the die-casting process. When mold replacement is required, the fixed plates 309 are rotated in the opposite direction to unlock, pushing the fixed clip 307 out of engagement with the L-shaped clip 401 and L-shaped clip 501, allowing the punch 4 and die 5 to be quickly removed from the mold mounting slot 303, enabling convenient assembly and disassembly of the punch 4 and die 5.

[0041] As a further embodiment of the present invention, the striking mechanism 6 includes a fixed plate 601, and the two ends of the fixed plate 601 are fixedly connected to the top of the opposite side of the two fixed side plates 1. A plurality of striking columns 602 are slidably installed through the fixed plate 601, and two striking columns 602 form a group. One end of each group of striking columns 602 passes through the fixed plate 601 and is fixedly installed with a pusher frame 603. A striking block 604 is fixedly installed at the end of the striking column 602 away from the pusher frame 603. The striking block 604 is closely attached to the side of the punch 4 and the die 5 near the L-shaped bracket 401 and the L-shaped bracket 501. A striking spring 605 is sleeved on the surface of the striking column 602 between the fixed plate 601 and the striking block 604. A rotating crankshaft 606 is rotatably installed between the two fixed side plates 1 on one side of the fixed plate 601 through a bearing. The rotating crankshaft 606 is composed of a plurality of cranks, and the cranks are slidably connected inside the pusher frame 603.

[0042] During operation, the striking mechanism 6 is fixed between two fixed side plates 1 by a fixed plate 601, providing a stable installation base for the entire striking mechanism 6. The striking column 602 is slidably installed through the fixed plate 601, with one end fixedly connected to the pusher 603, and the striking block 604 installed at the other end is close to one side of the convex mold 4 and the concave mold 5. The striking spring 605 is sleeved on the surface of the striking column 602 located between the fixed plate 601 and the striking block 604. The rotating crankshaft 606 between the two fixed side plates 1 is composed of multiple cranks. The pusher frame 603 has a longitudinal groove inside, and the cranks slide through and are connected to the longitudinal groove of the pusher frame 603. When the rotating crankshaft 606 rotates, the circular motion of its cranks is converted into a reciprocating thrust on the pusher frame 603, which pushes the pusher frame 603 to make linear reciprocating motion. This, in turn, pulls the striking column 602 to make high-frequency reciprocating sliding along the fixed plate 601, which drives the striking block 604 to reciprocate to strike the surfaces of the punch 4 and the die 5. The striking spring 605 makes a telescoping and rebounding motion with the sliding of the striking column 602, which not only provides a buffer for the striking block 604 to avoid damage to the mold or workpiece caused by hard knocking, but also improves the rebound and reset speed of the striking column 602 and the striking block 604, ensuring the continuity and efficiency of the striking action. The vibration force generated by the knocking eliminates the adsorption force between the workpiece and the forming surface of the punch 4 and the die 5, realizing the demolding of the workpiece.

[0043] As a further embodiment of the present invention, the transmission mechanism 8 includes a main transmission wheel 801, which is fixedly connected to the output shafts at both ends of the dual-output-shaft motor 7. A transmission belt 802 is sleeved on the surface of the main transmission wheel 801. The two rotating crankshafts 606 are respectively fixedly connected to the fixed side plate 1 through the fixed side plate 1 with a first linkage transmission wheel 803 or a second linkage transmission wheel 805. The top of the inner ring of the first transmission belt 802 is sleeved on the surface of the first linkage transmission wheel 803. A second transmission belt 804 is sleeved on the surfaces of the first linkage transmission wheel 803 and the second linkage transmission wheel 805. The first transmission belt 802 and the second transmission belt 804 are arranged vertically.

[0044] During operation, when the dual-output shaft motor 7 starts, it synchronously drives the two main drive wheels 801 to rotate. The main drive wheels 801 are connected to the linkage drive wheel 803 via the first drive belt 802, transmitting power to one of the rotating crankshafts 606. The linkage drive wheel 803 is then connected to the linkage drive wheel 805 via the second drive belt 804, transmitting power to the other rotating crankshaft 606, thus achieving synchronous rotation of the two rotating crankshafts 606. The first drive belt 802 and the second drive belt 804 are arranged perpendicularly to complete the power steering transmission, ensuring that the power can be efficiently and stably transmitted from the dual-output shaft motor 7 to the striking mechanisms 6 on both sides, so that the striking actions of the two striking mechanisms 6 are highly synchronized.

[0045] As a further embodiment of the present invention, the swaying discharge mechanism 9 includes four mounting columns 901. The four mounting columns 901 are respectively fixedly connected to the inside of the rectangular through groove 101. A swaying slider 902 is slidably mounted through the surface of the mounting column 901, and the swaying slider 902 slides close to the inner wall of the rectangular through groove 101. A swaying spring 903 is sleeved on both sides of the mounting column 901 and the swaying slider 902. A concave connecting frame 904 is fixedly installed between two swaying sliders 902 on the same side. A connecting strip 905 is rotatably mounted at the center of one side of the concave connecting frame 904 through a protrusion. The end of the connecting strip 905 away from the concave connecting frame 904 is rotatably connected to the edge of the main drive wheel 801 through the protrusion. A swaying frame 906 is fixedly installed between the four swaying sliders 902.

[0046] During operation, when the dual-shaft motor 7 drives the main drive wheel 801 to rotate, the circular motion of the main drive wheel 801 is converted into a reciprocating traction force on the concave connecting frame 904 through the connecting bar 905. This pulls the concave connecting frame 904 to make left and right reciprocating motions, which in turn drives the swaying slider 902 to make high-frequency reciprocating sliding along the mounting column 901. When the swaying slider 902 slides, it squeezes the swaying springs 903 on both sides. The extension and rebound of the swaying springs 903 not only provides the reset power for the swaying slider 902, but also amplifies the swaying amplitude of the swaying frame 906, so that the swaying frame 906 makes high-frequency reciprocating swaying between the two fixed side plates 1. The demolded workpiece falls into the interior of the swaying frame 906 and moves towards the discharge port of the frame under the action of swaying inertia, and finally quickly shakes out of the device, completing the fully automatic material discharge.

[0047] Working principle of this invention:

[0048] Insert the punch mold 4 and the concave mold 5 into the mold mounting slots 303 of the mounting frame 301 respectively. The slot structure is used to achieve initial positioning, ensuring that the forming surfaces of the punch mold 4 and the concave mold 5 are accurately aligned. Push the extrusion fixing strip 307, which causes the sliding blocks 305 at both ends to slide along the mounting slide rod 304. At the same time, the fixing spring 306 is compressed and deformed. After the L-shaped bracket 401 of the punch mold 4 and the L-shaped bracket 501 of the concave mold 5 are fully aligned with the fixing strip 307, release the fixing strip 307. The fixing spring 306 rebounds and pushes the sliding block 305 to reset, so that the fixing strip 307 automatically engages with the two sets of L-shaped brackets 401 and L-shaped brackets 501, completing the initial positioning of the mold. Rotate the fixing plates 309 at the four corners of the mold mounting slot 303 to engage and lock them with the fixing hooks 308, ensuring that the mold does not shift or loosen during die casting.

[0049] After the mold is installed, the electric push rod 201 is retracted, and the push block 202 drives the moving push plate 2 to slide steadily upward along the T-shaped limiting block 102 on the outside of the fixed side plate 1. The L-shaped slide groove 204 and the pushing slide groove 205 on the moving push plate 2 coincide with the limiting slide groove 104 and the limiting slide groove 205 on the fixed side plate 1, guiding the push protrusions 302 on both sides of the mounting frame 301 to move back along the slide groove. Under the guidance of the slide groove, the two mounting frames 301 move closer to the middle, causing the convex mold 4 and the concave mold 5 to close tightly, forming a closed die-casting cavity, and injecting molten metal into the cavity. Zinc alloy, after pressure holding and cooling, completes the die casting of the part. After die casting, the electric push rod 201 is extended, and the push block 202 drives the moving push plate 2 to slide down along the T-shaped limit block 102. The moving push plate 2 drives the L-shaped slide 204 and the push slide 205 to move synchronously, so that the push protrusion 302 slides along the inclined and horizontal trajectory in the overlapping slide. Guided by the irregular structure of the slide, the two mounting frames 301 move away from each other between the two fixed side plates 1 and undergo directional deflection, which drives the convex mold 4 and the concave mold 5 to tilt and separate synchronously. After the mold tilts, its back side is precisely attached to the striking block 604.

[0050] After the mold is aligned, the dual-shaft motor 7 is started to drive the main drive wheel 801 to rotate synchronously. The main drive wheel 801 drives the linkage drive wheel 803 to rotate via the first drive belt 802. The first linkage drive wheel 803 then drives the second linkage drive wheel 805 to rotate synchronously via the second drive belt 804, so that the two rotating crankshafts 606 rotate at the same speed and in the same direction. The cranks on the rotating crankshafts 606 slide in the pusher frame 603, converting the circular motion into the linear reciprocating motion of the pusher frame 603. The pusher frame 603 pulls the striking column 602 to slide back and forth along the fixed plate 601 at high frequency, driving the striking block 604 to continuously and elastically strike the back of the punch mold 4 and the concave mold 5. The high-frequency vibration force quickly eliminates the adhesion force between the workpiece and the mold cavity, making... The molded workpiece detaches from the mold and falls freely into the lower swaying frame 906. While the dual-shaft motor 7 drives the striking action, the edge of the main drive wheel 801 pulls the concave connecting frame 904 to reciprocate left and right through the connecting strip 905. The concave connecting frame 904 drives the swaying slider 902 to slide at high frequency along the mounting column 901 in the rectangular through groove 101. The swaying springs 903 on both sides of the swaying slider 902 extend and retract with the sliding, providing the slider with reset power and amplifying the swaying amplitude. The four swaying sliders 902 synchronously pull the swaying frame 906 to reciprocate at high frequency between the two fixed side plates 1. The workpiece that falls into the swaying frame 906 moves towards the discharge port under the action of swaying inertia and is finally quickly shaken out of the device, completing the fully automatic discharge.
