Description

Technical Field

[0001] This invention relates to the technical field of die casting machines, and in particular to a die casting machine for aluminum products. Background Technology

[0002] Aluminum die casting involves pouring molten aluminum or aluminum alloy into a sand mold or metal mold cavity, and then cooling it to obtain aluminum or aluminum alloy parts of various shapes and sizes. A die casting machine uses pressure to inject molten metal into a mold, where it cools and solidifies, resulting in a solid metal casting after the mold is opened.

[0003] Typically, after a single casting is demolded, a release agent needs to be sprayed onto the inner cavities of both molds. This process requires operators to hold spray guns and spray the agent onto the inner cavities of the two molds on both sides. This is time-consuming and labor-intensive, increasing the workload of the operators. Moreover, it is difficult to ensure the uniformity of the release agent spraying into the mold cavities. Alternatively, auxiliary equipment can be added to spray the two molds after they have been opened. However, because the auxiliary equipment cannot reach the center of the mold cavity, the spraying effect is poor and cannot evenly and fully cover the inner cavity of the mold. In addition, the inner cavity needs to be cleaned before spraying the release agent. This is usually done manually with a handheld air gun, which is labor-intensive and greatly reduces the efficiency of aluminum die casting in the workshop. Furthermore, during the air gun cleaning process, the fumes that overflow from the mold opening are blown around again, degrading the workshop environment. Summary of the Invention

The top of the blower piston rod is fixedly installed on the U-shaped moving plate. The connecting rod moves within the U-shaped moving plate.

[0009] An air inlet pipe and an air outlet pipe are fixedly installed on the side of the bottom of the blower away from the fixed plate, and the air outlet pipe is connected to the blower base. Several blower nozzles are fixedly installed on the side of the blower base near the fixed mold and the movable mold.

[0010] As a preferred embodiment of the present invention, the demolding spray assembly further includes a drive arm and a connecting arm. The cleaning spray box is fixedly installed at the bottom of the U-shaped internal gear ring. A drive motor is fixedly installed inside the cleaning spray box. The output end of the drive motor is fixedly installed with a drive arm that moves outside the cleaning spray box via a rotating shaft. Swing arms are movably connected to both ends of the cleaning spray box on the side away from the fixed plate via rotating shafts. A connecting arm is movably connected to the drive arm, and the swing arm is movably connected to the connecting arm. Driven arms are movably connected to the bottom ends of the cleaning spray box on the side away from the U-shaped internal gear ring via rotating shafts. A connecting plate is movably connected between the bottom of the swing arm and the driven arm via a rotating shaft. A spray seat and a blower seat are installed on the connecting plate. Several spray heads are fixedly installed on the side of the spray seat near the fixed mold and the movable mold.

[0011] As a preferred embodiment of the present invention, the open-mold smoke extraction assembly further includes an arc-shaped support rod and a smoke seat. An arc-shaped support rod is fixedly installed on the top of the fixed plate, and a smoke cylinder is fixedly installed on the top of the arc-shaped support rod. A smoke piston plate is movably arranged inside the smoke cylinder. A smoke piston rod is fixedly installed at the center of the smoke piston plate on one side near the fixed plate. The top of the smoke piston rod passes through the smoke cylinder and is fixedly installed on the movable block. Arc-shaped mounting rods are fixedly installed at both ends of the bottom of the cleaning spray box, and a smoke seat is fixedly installed at the bottom of the arc-shaped mounting rods.

[0012] Several suction heads are evenly installed at the bottom of the flue gas holder. An exhaust pipe and a suction pipe are fixedly installed at the end of the flue gas cylinder away from the fixed plate, and the suction pipe is connected to the flue gas holder.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. In this invention, the spiral plate set by the deep translation component, during the descent process, works in conjunction with the residue cleaning component to perform deep cleaning of the mold cavity; during the ascent, it works with the demolding spray component to achieve full coverage of the inner cavity surface with demolding agent spraying. The deep translation component drives the cleaning spray box to complete the descent cleaning, ascent spraying and horizontal movement dust collection operations between the inner cavities of the two molds in sequence. The three major functions of cleaning, spraying and fume absorption are highly integrated into one. With the help of the precision transmission system composed of the spiral internal gear ring and the drive gear, the whole process is completed continuously in one operating cycle. The structural design is compact and the operation is stable and reliable, realizing an efficient, continuous and automated work cycle.

[0014] 2. In this invention, the cleaning spray box is moved to the center position between the two molds by the downward movement of the return plate in the deep translation component. As the cleaning spray box gradually descends to the center of the mold, the blower nozzle equipped with the blower seat in the residue cleaning component begins to clean the inner cavity of the mold. The aluminum product debris remaining in the cavity is removed by blowing air. The blowing cleaning adopts the airflow direction from top to bottom, which can significantly enhance the cleaning effect on the inner wall of the mold cavity. It ensures that the internal residue is completely discharged from the mold cavity under the dual action of wind force and gravity, effectively avoiding the problem of secondary adhesion of residue or contamination of the mold cavity, thereby maintaining the continuous, efficient and clean operation of the mold.

[0015] 3. In this invention, the drive arm rotates by the drive motor of the deep translation component and the cleaning spray box. The drive arm transmits power to the swing arm and the driven arm through the connecting arm, causing them to perform arc swing. Subsequently, the connecting plate installed at the bottom of the swing arm and the driven arm generates horizontal rotation, which in turn drives the blower seat and blower nozzle fixed on it to achieve arc swing cleaning. The descending cleaning spray box, together with the swinging connecting plate, significantly enhances the cleaning effect on the inner cavity of the mold, achieving wider coverage and deeper residue removal.

[0016] 4. In this invention, the residue cleaning component and the mold release spraying component work together. The spray head and blower nozzle integrated on the connecting plate perform in-depth cleaning and comprehensive spraying of the mold cavity, respectively. In the cleaning stage, high-pressure blower from top to bottom is used to effectively remove residual aluminum slag. In the spraying stage, atomized spraying from bottom to top is used to achieve uniform coverage of the mold release agent on the surface of the cavity. The rotating plate in the lifting movement coordinates the alternating operation of the two components to ensure that the cleaning and spraying processes do not interfere with each other and are connected in an orderly manner. This integrated operation not only significantly improves the efficiency and quality of mold processing, but also avoids cross-contamination, thereby improving the continuous operation capability and comprehensive production capacity of the aluminum product production workshop.

[0017] 5. In this invention, the smoke piston rod in the mold-opening smoke extraction assembly drives the smoke piston plate to move, creating a negative pressure environment inside the smoke cylinder. With the help of the connection between the suction pipe and the smoke seat, the high-temperature smoke generated during mold opening is captured by the suction head. While adsorbing the smoke, the suction head rises with the smoke airflow, achieving dynamic tracking and absorption. This working method of rising and adsorbing simultaneously significantly enhances the efficiency of smoke collection, expands the coverage area, and thus improves the overall ability of the mold-opening smoke extraction assembly to handle high-temperature smoke.

[0018] 6. In this invention, the drive motor of the cleaning spray box of the deep translation component is used to drive the drive arm to rotate, and then the power is transmitted to the swing arm and driven arm through the connecting arm, driving them to complete the arc swing. The connecting plate at the bottom of the swing arm and driven arm will then generate horizontal rotation, driving the spray seat and spray head installed on it to spray the release agent evenly into the mold cavity. During the spraying process, the spray head moves from bottom to top, and at the same time, it cooperates with the arc swing to achieve the release agent coverage under the swing and upward composite motion, which significantly expands the spraying range and ensures that the surfaces of the two cleaned mold cavities are completely and evenly covered with the release agent, effectively improving the spraying quality and consistency.

[0021] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0022] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an aluminum die-casting machine includes a die-casting machine body 10, on which a fixed mold 11 and a movable mold 12 are mounted. A fixed plate 20 is fixedly mounted on the top of the movable mold 12 via an arc-shaped support foot 21. A deep-penetrating translation component is mounted on the fixed plate 20 for cleaning the inner cavities of the two molds and spraying a release agent. The deep-penetrating translation component includes a spiral plate 30, a spiral internal toothed ring 31, and a cleaning spray box 32. A residue cleaning component and a release spray component are also mounted on the spiral plate 30. An aluminum liquid injection cylinder 13 is fixedly mounted on the side of the fixed mold 11 away from the movable mold 12, into which molten aluminum liquid is injected. The die-casting machine body 10 also includes a hydraulic rod 14 for driving the movable mold 12. The movable mold 12 is mounted on the die-casting machine body 10 via a folding pusher 15. Guide rods 16 are also provided around the movable mold 12. The guide rods 16 cooperate with the movable mold 12 to achieve stable mold closing with the fixed mold 11. The deep translation component also includes a movable block 25 and a limiting seat 38. The fixed plate 20 has a limiting groove 22 on the side near the fixed mold 11. The movable block 25 is slidably connected in the limiting groove 22. The limiting seats 38 are fixedly installed at both ends of the movable block 25 on the side near the fixed mold 11. The spiral plate 30 is slidably disposed between the limiting seats 38. A spiral internal toothed ring 31 is fixedly installed on the side of the spiral plate 30 away from the fixed plate 20. The spiral internal toothed ring 31 is a ring structure and includes a straight toothed part and a semi-circular toothed part.

[0023] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The hydraulic rod 14, in conjunction with the guide rod 16, drives the folding pusher 15 to unfold. During the unfolding process, the folding pusher 15 stably closes the movable mold 12 and the fixed mold 11. After the mold is closed, molten aluminum is injected into the mold under high pressure. The aluminum product is effectively die-cast in the mold cavity of the movable mold 12 and the fixed mold 11. After the die-cast product inside cools down, the mold is opened and the die-cast product is removed by a robotic arm.

[0024] See Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The fixed plate 20 has T-shaped grooves 23 on the upper and lower sides of the limiting groove 22. T-shaped sliders 24 are slidably connected in the T-shaped grooves 23. The T-shaped sliders 24 are fixedly installed at both ends of the movable block 25, so that the movable block 25 can move horizontally in the limiting groove 22. A rotary motor 27 is fixedly installed on the side of the fixed plate 20 away from the spiral plate 30 through the motor plate 26. A rotary shaft 28 is fixedly installed at the output end of the rotary motor 27. The rotary shaft 28 extends through the fixed plate 20 to one side of the spiral plate 30. A drive gear 29 is fixedly installed at the top of the rotary shaft 28. The drive gear 29 is movably meshed with the spiral internal gear ring 31. The drive gear 29 meshes with the spiral internal gear ring 31 to drive the spiral plate 30 to perform lifting and horizontal reciprocating motion.

[0025] See Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The rotary motor 27 under the motor plate 26 drives the drive gear 29 on the rotating shaft 28 to rotate. The drive gear 29 meshes with the spiral internal gear ring 31, causing the spiral plate 30 to move within the limiting seat 38. The spiral internal gear ring 31 includes a straight rack portion and a semi-circular rack portion. During mold opening, the drive gear 29 meshes with the semi-circular rack portion at the bottom of the spiral plate 30. Under the action of the meshing drive gear 29, the semi-circular rack portion drives the spiral plate 30 on the entire spiral internal gear ring 31 to move horizontally. The spiral-shaped internal gear ring 31 changes the position of the driving gear 29 within the spiral-shaped internal gear ring 31 through the semi-circular rack portion, so that the engagement between one side of the spiral-shaped internal gear ring 31 and the driving gear 29 changes to the engagement between the other side of the spiral-shaped internal gear ring 31 and the driving gear 29. The spiral plate 30 will undergo stable horizontal movement through the T-shaped slide groove 23 and T-shaped slider 24 in the limiting groove 22. At the same time, the spiral plate 30 also undergoes upward movement in the limiting seat 38. That is, the spiral plate 30 undergoes vertical movement while moving horizontally.

[0026] See Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10The retractable plate 30, which is deeply integrated into the translation component, works with the residue cleaning component to perform deep cleaning of the mold cavity during the descent process. The residue cleaning component includes a blower 40 and a blower seat 41. The blower seat 41 is movable on the bottom outer side of the cleaning spray box 32. The residue cleaning component also includes a connecting plate 60 and a retractable motion plate 64. The blower 40 is fixedly installed on the side of the fixed plate 20 away from the retractable plate 30. The connecting plate 60 is fixedly installed at both ends of the top of the retractable plate 30. The connecting rod 61 is fixedly installed on the top of the connecting plate 60. The blower piston plate 62 is movably arranged inside the blower 40. The blower piston rod 63 is fixedly installed on the top of the blower piston plate 62. The top of the blower piston rod 63 extends through to the top outer side of the blower 40, and the retractable motion plate 64 is fixedly installed at the top of the blower piston rod 63. The connecting rod 61 is movable in the retractable motion plate 64. The connecting rod 61 works in conjunction with the retractable motion plate 64 to drive the blower piston rod 63 to move synchronously.

[0027] See Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10 An air inlet pipe 65 and an air outlet pipe 66 are fixedly installed on the bottom side of the blower 40 away from the fixed plate 20. The air outlet pipe 66 is connected to the blower seat 41. One-way valves are installed on both the air inlet pipe 65 and the air outlet pipe 66. The air inlet pipe 65, in conjunction with the one-way valve, can only fill the inside of the blower 40 with gas. The air outlet pipe 66, in conjunction with the one-way valve, can only discharge gas in one direction, so that the gas enters the inside of the blower seat 41 in one direction. Several blower nozzles 45 are fixedly installed on the side of the blower seat 41 near the fixed mold 11 and the movable mold 12. The blower nozzles 45 are used to perform deep cleaning of the mold cavity.

[0028] See Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 When the drive gear 29 begins to mesh with the straight rack portion of the spiral internal gear ring 31, the drive gear 29 meshes with the spiral internal gear ring 31, causing the spiral plate 30 to descend in the limiting seat 38. At this time, the movable block 25 moves to the end of the limiting groove 22 away from the flue gas cylinder 50. During the descent, the spiral plate 30 moves down through the connecting plate 60, causing the connecting rod 61 to descend. The connecting rod 61 moves down synchronously through the spiral motion plate 64 at the top, causing the blower piston rod 63 to descend. The blower piston rod 63 moves down through the blower piston plate 62 inside the blower cylinder 40. The blower piston plate 62 generates positive pressure inside the blower cylinder 40. The air inside the blower cylinder 40 will enter the blower seat 41 through the exhaust pipe 66 and then be discharged through the blower nozzle 45 on the blower seat 41. See Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As the retractable plate 30 descends, it carries the cleaning spray box 32 to the center of the two molds. During this descent, the blower nozzles 45 on the blower seat 41 of the cleaning spray box 32 clean the inner cavity of the mold, blowing away any residue from the aluminum products inside. This top-down blowing cleaning enhances the cleaning ability of the mold cavity, ensuring that all residue is completely expelled from the mold cavity by the force of the airflow and gravity, preventing secondary contamination. Simultaneously, the drive motor 35 inside the cleaning spray box 32 drives the drive arm 33 to rotate. The drive arm 33, through the connecting arm 34, drives the swing arm 36 in conjunction with the driven arm 37 to perform an arc-shaped swing motion. The connecting plate 42 at the bottom of the swing arm 36 and the driven arm 37 rotates horizontally, and the blower seat 41 on the connecting plate 42, in conjunction with the blower nozzles 45, performs an arc-shaped swing cleaning, significantly improving the cleaning effect on the inner cavity of the mold. See Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 9 and Figure 10 The recessed sliding plate 30, during its ascent, works in conjunction with the demolding spray assembly to fully cover the mold cavity with spray. The demolding spray assembly includes a swing arm 36, a spray base 43, a drive arm 33, and a connecting arm 34. The cleaning spray box 32 is fixedly installed at the bottom of the recessed internal gear ring 31. A drive motor 35 is fixedly installed inside the cleaning spray box 32. The output end of the drive motor 35 is fixedly mounted with a drive arm 33 that moves outside the cleaning spray box 32 via a rotating shaft. The swing arm 36 is movably connected to both ends of the cleaning spray box 32 on the side away from the fixed plate 20 via a rotating shaft. The connecting arm 34 is movably connected to the drive arm 33. The 36 is movably connected to the connecting arm 34. The cleaning spray box 32 is movably connected to the driven arm 37 at both ends of the bottom of the side away from the inner toothed ring 31 via a rotating shaft. The bottom of the swing arm 36 and the driven arm 37 are movably connected to the connecting plate 42 via a rotating shaft. The driving arm 33 drives the connecting arm 34 to swing back and forth. The connecting arm 34 swings the connecting plate 42 in an arc shape with the swing arm 36 and the driven arm 37, so that the connecting plate 42 swings in a fan shape at the bottom. The spray seat 43 and the blower seat 41 are installed on the connecting plate 42. Several spray heads 44 are fixedly installed on the side of the spray seat 43 near the fixed mold 11 and the movable mold 12.

[0029] See Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 9 and Figure 10 After the driving gear 29 meshes with the semi-circular rack at the top of the loop-shaped internal gear ring 31, the driving gear 29 changes to mesh with the other side of the loop-shaped internal gear ring 31. At this time, the driving gear 29 meshing with the loop-shaped internal gear causes the loop plate 30 to rise on the limit seat 38. The loop plate 30, along with the cleaning spray box 32, rises synchronously between the two mold cavities. The drive motor 35 inside the cleaning spray box 32 drives the drive arm 33 to rotate. The drive arm 33, through the connecting arm 34, drives the swing arm 36 to cooperate with the driven arm. 37 undergoes an arc-shaped swing motion, and the connecting plate 42 at the bottom of the swing arm 36 and the driven arm 37 rotates horizontally. The spray seat 43 on the connecting plate 42, together with the spray head 44, sprays the release agent into the mold cavity. During the upward process, the spray head 44 achieves arc-shaped swing while spraying the release agent, so that the two cleaned mold cavities are completely covered with the release agent. The arc-shaped swing expands the spray range of the release agent, and the release agent is sprayed from bottom to top, resulting in good spray coverage, until the return plate 30 rises to the top outside of the movable mold 12.

[0030] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10 The fixed plate 20 is equipped with a mold opening smoke extraction component, which is used to absorb the high-temperature fumes that overflow after the die-casting mold is opened. Before descending into the inner cavity of the mold, the return plate 30 of the deep translation component cooperates with the mold opening smoke extraction component to draw the overflowing high-temperature fumes into the inside of the smoke cylinder 50. The mold opening smoke extraction component also includes an arc-shaped support rod 51 and a smoke seat 52. The arc-shaped support rod 51 is fixedly installed on the top of the fixed plate 20, and the smoke cylinder 50 is fixedly installed on the top of the arc-shaped support rod 51. A smoke piston plate 53 is movably arranged inside the smoke cylinder 50. A smoke piston rod 54 is fixedly installed at the center of the smoke piston plate 53 on one side close to the fixed plate 20. The top of the smoke piston rod 54 passes through the smoke cylinder 50 and is fixedly installed on the movable block 25. Arc-shaped mounting rods 55 are fixedly installed at both ends of the bottom of the cleaning spray box 32, and a smoke seat 52 is fixedly installed at the bottom of the arc-shaped mounting rods 55.

[0031] See Figure 5 , Figure 6 , Figure 7 and Figure 8Several suction heads 56 are evenly installed at the bottom of the flue gas seat 52. An exhaust pipe 57 and a suction pipe 58 are fixedly installed at the end of the flue gas cylinder 50 away from the fixed plate 20. The suction pipe 58 is connected to the flue gas seat 52. One-way valves are installed on both the exhaust pipe 57 and the suction pipe 58. The gas inside the flue gas cylinder 50 can only be filled with flue gas through the suction pipe 58 in conjunction with the one-way valve. The flue gas inside the flue gas cylinder 50 can only be discharged through the exhaust pipe 57 in conjunction with the one-way valve. The high-temperature flue gas from die casting is absorbed, cooled, and then discharged for filtration and purification.

[0032] See Figure 5 , Figure 6 , Figure 7 and Figure 8 When the rotary plate 30 moves horizontally, it pulls the flue gas piston plate 53 through the flue gas piston rod 54. The flue gas piston plate 53 creates a negative pressure inside the flue gas cylinder 50. The flue gas cylinder 50 absorbs the high-temperature flue gas generated during mold opening through the suction pipe 58 and the flue gas seat 52 in conjunction with the suction head 56. When the suction head 56 on the flue gas seat 52 absorbs the flue gas, it rises, so that the suction head 56 absorbs the high-temperature flue gas as it rises, which greatly improves the flue gas absorption effect, expands the flue gas absorption range, and improves the flue gas absorption capacity.

[0033] Working principle: Molten aluminum to be die-cast is injected into the aluminum injection cylinder 13. The hydraulic rod 14, in conjunction with the guide rod 16, drives the folding push frame 15 to unfold. During the unfolding process, the folding push frame 15 stably closes the movable mold 12 and the fixed mold 11. After the mold is closed, the molten aluminum is injected into the mold under high pressure. The aluminum product is effectively die-cast in the mold cavity of the movable mold 12 and the fixed mold 11. After the die-cast product inside cools, the mold is opened and the die-cast product is removed by a robotic arm.

[0034] When the die-cast product is removed from the mold, the drive gear 29 on the rotating shaft 28 is driven to rotate by the rotary motor 27 under the motor plate 26. The drive gear 29 meshes with the spiral internal gear ring 31, which drives the spiral plate 30 to move in the limiting seat 38. The spiral internal gear ring 31 includes a straight rack part and a semi-circular rack part. When the mold is opened, the drive gear 29 meshes with the semi-circular rack part at the bottom of the spiral plate 30. Under the action of meshing with the drive gear 29, the semi-circular rack part drives the spiral plate 30 on the entire spiral internal gear ring 31 to move horizontally. The spiral internal gear ring 31 changes the position of the drive gear 29 in the spiral internal gear ring 31 through the semi-circular rack part, so that the meshing of one side of the spiral internal gear ring 31 with the drive gear 29 changes to the meshing of the other side of the spiral internal gear ring 31 with the drive gear 29. The U-shaped plate 30 will move horizontally in a stable manner through the T-shaped slide 23 and T-shaped slider 24 in the limiting groove 22. At the same time, the U-shaped plate 30 will also move upward in the limiting seat 38. That is, the U-shaped plate 30 will move vertically while moving horizontally. When the U-shaped plate 30 moves horizontally, it will pull the flue gas piston plate 53 through the flue gas piston rod 54. The flue gas piston plate 53 will create a negative pressure inside the flue gas cylinder 50. The flue gas cylinder 50 will absorb the high-temperature flue gas generated by the mold opening through the dust suction pipe 58 and the flue gas seat 52 in conjunction with the dust suction head 56. When the dust suction head 56 on the flue gas seat 52 absorbs the flue gas, it will move upward, so that the dust suction head 56 absorbs the high-temperature flue gas as it rises, which greatly improves the flue gas absorption effect, expands the flue gas absorption range, and improves the flue gas absorption capacity.

[0035] When the drive gear 29 begins to mesh with the straight rack portion of the spiral internal gear ring 31, the drive gear 29 meshes with the spiral internal gear ring 31, causing the spiral plate 30 to descend in the limiting seat 38. At this time, the movable block 25 moves to the end of the limiting groove 22 away from the flue gas cylinder 50. During the descent, the spiral plate 30 moves down through the connecting plate 60, causing the connecting rod 61 to descend. The connecting rod 61 moves down synchronously through the spiral motion plate 64 at the top, causing the blower piston rod 63 to descend. The blower piston rod 63 moves down through the blower piston plate 62 inside the blower cylinder 40. The blower piston plate 62 generates positive pressure inside the blower cylinder 40. The air inside the blower cylinder 40 will enter the blower seat 41 through the exhaust pipe 66 and then be discharged through the blower nozzle 45 on the blower seat 41. As the folding plate 30 descends, it carries the cleaning spray box 32 into the center of the two molds. As the cleaning spray box 32 descends at the center of the mold, the blower nozzles 45 on the blower seat 41 of the cleaning spray box 32 clean the inner cavity of the mold, blowing away the residue of the aluminum products inside the mold cavity. The top-down blowing cleaning can improve the cleaning ability of the inner cavity of the mold, so that the internal residue is completely discharged from the mold cavity by the blowing force and gravity, and the internal residue will not cause secondary pollution to the mold cavity.

[0036] Meanwhile, the drive arm 33 is driven to rotate by the drive motor 35 inside the cleaning spray box 32. The drive arm 33 drives the swing arm 36 to swing in an arc shape with the driven arm 37 through the connecting arm 34. The connecting plate 42 at the bottom of the swing arm 36 and the driven arm 37 rotates horizontally. The blower seat 41 on the connecting plate 42 works with the blower nozzle 45 to swing in an arc shape for cleaning, which greatly improves the cleaning effect on the inner cavity of the mold.

[0037] When the drive gear 29 engages at the top position of the spiral internal gear ring 31, the blower piston plate 62 in the blower duct 40 moves to the bottom, and the blower nozzle 45 no longer blows air to clean the mold cavity. Similarly, the drive gear 29 re-enters the semi-circular rack part of the spiral internal gear ring 31, and the drive gear 29 engages with the spiral internal gear ring 31, causing the movable block 25 in the limiting groove 22 to move horizontally back to its original position. At this time, the smoke piston rod 54 in the mold opening smoke extraction assembly, along with the smoke piston plate 53, generates positive pressure inside the smoke extraction duct 50. The smoke previously drawn into the smoke extraction duct 50 is concentrated and discharged into the external purification equipment through the exhaust pipe 57 to filter and purify the smoke, improving the workshop working environment. In this way, the high-temperature smoke can be cooled in the smoke extraction duct 50 and can also be effectively filtered and absorbed.

[0038] Similarly, after the driving gear 29 meshes with the semi-circular rack at the top of the loop-shaped internal gear ring 31, the driving gear 29 changes to mesh with the other side of the loop-shaped internal gear ring 31. At this time, the driving gear 29 meshing with the loop-shaped internal gear causes the loop plate 30 to rise on the limit seat 38. The loop plate 30, along with the cleaning spray box 32, simultaneously rises between the two mold cavities. The drive motor 35 inside the cleaning spray box 32 drives the drive arm 33 to rotate. The drive arm 33, through the connecting arm 34, drives the swing arm 36 to cooperate with the driven arm 37 to perform an arc-shaped swing motion. The connecting plate 42 at the bottom of the driven arm 36 and the driven arm 37 rotates horizontally. The spray seat 43 on the connecting plate 42, together with the spray head 44, sprays the release agent into the mold cavity. During the upward movement, the spray head 44 sprays the release agent while swinging in an arc, so that the two cleaned mold cavities are completely covered with the release agent. The arc swing expands the spray range of the release agent, and the release agent is sprayed from bottom to top, resulting in good spray coverage. Until the return plate 30 rises to the top outside of the movable mold 12, the return plate 30 resets and enters the next stage of flue gas dust collection, cleaning of the cavity and spraying of release agent.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
