Description

Technical Field

[0001] This invention relates to the field of casting processing technology, and more specifically, to an automatic casting shaping device. Background Technology

[0002] After casting is completed, it needs to be cooled and solidified into a specified shape. Since there are many types of castings, during the casting process, the casting needs to be die-cast and shaped so that the shape of the casting meets the processing requirements. Therefore, die-casting and shaping equipment is required.

[0003] After die casting and shaping, the casting temperature is relatively high. In existing technologies, to accelerate the shaping process, the upper and lower molds are separated, and the casting is cooled using methods such as air cooling. After cooling, the casting is removed by the operator to proceed with the next casting. However, this method is prone to deformation during the cooling process, especially for thinner castings, affecting the shaping quality. If the casting is cooled without separating the upper and lower molds, the cooling rate is slow due to the sealed state, severely impacting the shaping efficiency. Therefore, to solve the above technical problems, this application proposes an automatic casting shaping device. Summary of the Invention

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0043] Please combine Figures 1 to 11 As shown, an automatic forming and processing device for castings includes a hydraulic cylinder 90 fixedly mounted on a fixed plate 11, a fixed block 91 fixedly mounted on the movable end of the hydraulic cylinder 90, a pair of movable blocks 92 slidably mounted inside the fixed block 91, and a second spring 93 fixedly disposed between the two movable blocks 92. The processing device also includes:

[0044] The conveyor chain 10 is rotatably mounted on the fixed plate 11. The top end of the conveyor chain 10 is a horizontal section 101, and its bottom end consists of a pair of water inlets 103 and a turning section 104 disposed between the two water inlets 103. The two ends of the conveyor chain 10 in the length direction are vertical sections 102, and the horizontal section 101 is disposed directly below the hydraulic cylinder 90.

[0045] A water tank 20 is located at the bottom of the conveyor chain 10. A partition 21 is fixedly installed on the inner surface of the water tank 20. The partition 21 divides the internal cavity of the water tank 20 into a warm water tank 22 and a cold water tank 23. Two water inlets 103 are located in the warm water tank 22 and the cold water tank 23 respectively, and both water inlets 103 are submerged in water.

[0046] Mounting plates 60 are evenly spaced along the travel direction of the conveyor chain 10. A lower mold 30 and an upper mold 50 are vertically mounted on the inner surface of the mounting plates 60. A mold frame 40 is fixedly mounted on the inner surface of the mounting plates 60, located between the lower mold 30 and the upper mold 50. The lower mold 30 has a receiving cavity 301 for accommodating the mold frame 40. The lower mold 30, mold frame 40, and upper mold 50, when combined, form a die-casting cavity. The receiving cavity 301 is located at the edge of this die-casting cavity. A sliding rod 53 is fixedly installed between the upper surface of the frame 40 and the mounting plate 60. An elastic element is provided between the upper mold 50 and the mounting plate 60. The elastic element can be set as a first spring 52. One end of the first spring 52 is fixedly connected to the mounting plate 60, and the other end of the first spring 52 is fixedly connected to the upper mold 50. A stop block 501 is fixedly installed on the upper surface of the upper mold 50. A rotating rod 70 is rotatably installed on the mounting plate 60. A guide block 701 is fixedly installed on the rotating rod 70. The upper surface of the guide block 701 is an inclined surface.

[0047] A deflection assembly is provided between one end of the rotating rod 70 and the fixed plate 11. The deflection assembly consists of a first part and a second part. The first part is fixedly installed on one end of the rotating rod 70, and the second part is fixedly installed on the fixed plate 11. When the first part is connected to the second part, the rotating rod 70 is driven to rotate, causing the guide block 701 to disengage from directly above the upper mold 50. A reset component is also provided between the rotating rod 70 and the mounting plate 60. When the first part is separated from the second part, the reset component resets the rotating rod 70. The reset component is a torsion spring 83. One end of the torsion spring 83 is fixedly connected to the rotating rod 70, and the other end is fixedly connected to the mounting plate 60.

[0048] It should be noted that a track plate 51 is fixedly installed on the upper surface of the upper mold 50. A channel is formed on the track plate 51, and a first guide surface 511 is provided at one end of the channel. A positioning cavity 512 is formed inside the track plate 51, and a second guide surface 513 is provided at the end of the positioning cavity 512 away from the first guide surface 511. During the process of driving the upper mold 50 to move directly below the hydraulic cylinder 90, the fixed block 91 enters the channel from one end. When the two movable blocks 92 enter the positioning cavity 512, the conveyor chain 10 stops moving. The movable end of the pressure cylinder 90 extends, driving the upper mold 50 to move downwards for die casting and shaping. The downward movement of the upper mold 50 first presses against the upper surface of the guide block 701, causing the rotating rod 70 to rotate. After the upper mold 50 passes the guide block 701, the elastic action of the torsion spring 83 causes the guide block 701 to rotate and return to its original position, so that the lower surface of the guide block 701 adheres to the upper surface of the upper mold 50. This keeps the lower mold 30, mold frame 40, and upper mold 50 in a combined state. After die casting is completed, the conveyor chain 10 continues to move, and the movable block 92 presses against the second guide surface 513. Then, the two movable blocks 92 move into the fixed block 91, allowing the fixed block 91 to leave the channel on the track plate 51. The lower mold 30, mold frame 40, and upper mold 50 move together with the mounting plate 60, first entering the warm water tank 22 along one water inlet 103 to slowly cool the casting. When the mounting plate 60 passes the turning part 104 and enters the other water inlet 103, the lower mold 30, mold frame 40, and upper mold 50 enter the cold water tank 23 for further cooling. During this cooling process, the casting is cooled sequentially using warm water... The water and cold water are used for slow cooling, and the lower mold 30, mold frame 40 and upper mold 50 are always in a closed state, which can suppress the deformation of the casting during cooling, making the shape of the finished casting more regular and thus improving the quality of the finished casting. For this processing device, multiple mounting plates 60 are set in the travel direction of the conveyor chain 10, so that die casting and shaping can be carried out continuously. Compared with the prior art, after die casting is completed, it is necessary to wait for the casting to cool down before taking out the finished product for die casting and shaping, which also improves the processing efficiency of casting.

[0049] It should be further explained that a support plate 13 is fixedly installed on the fixed plate 11 by a fixing rod. The support plate 13 is located directly below the hydraulic cylinder 90. When the upper mold 50 moves to the position directly below the hydraulic cylinder 90, the lower surface of the lower mold 30 is attached to the upper surface of the support plate 13 to support the lower mold 30 and increase the pressure that the lower mold 30 can bear. A limiting plate 601 is fixedly installed on the inner surface of the mounting plate 60. The limiting plate 601 is located above the upper mold 50. When the upper mold 50 rises under the elastic force of the first spring 52 until the upper mold 50 is attached to the lower surface of the limiting plate 601, the first spring 52 still has an upward contraction force, which is conducive to the upper mold 50 being at the specified height each time, so that the fixing block 91 can smoothly enter the channel of the track plate 51.

[0050] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with specific working methods as follows. Example

[0051] A threaded rod 31 is rotatably mounted on the mounting plate 60. The top end of the threaded rod 31 is rotatably connected to the mold frame 40. One end of the threaded rod 31 passes through the interior of the lower mold 30 and is threadedly connected to the lower mold 30. A limit rod 33 is fixedly installed between the mounting plate 60 and the mold frame 40. One end of the limit rod 33 passes through the interior of the lower mold 30. A first gear 32 is fixedly mounted on one end of the threaded rod 31. A first gear rail 34 is fixedly installed on the inner surface of the water tank 20 and inside the cold water tank 23. After cooling by cold water, the conveyor chain 10... During the movement, the first gear 32 meshes with the first gear rail 34, causing the threaded rod 31 to rotate. The lower mold 30 gradually moves downward until its upper surface is below the lower surface of the mold frame 40, at which point the casting is supported on the mold frame 40. One end of the mold frame 40 is set to be open, and a square column 61 is fixedly installed on the outer surface of the mounting plate 60. The square column 61 is rotatably connected to the conveyor chain 10, and a second gear 62 is fixedly installed on the square column 61. The outer surface of the mounting plate 60 also rotates... A third gear 64 is installed, which meshes with the second gear 62. A limit frame 12 is fixedly installed on the fixed plate 11, and the limit frame 12 of the square column 61 fits tightly. A notch 121 is opened at the limit frame 12. A third gear rail 63 is fixedly installed on the fixed plate 11 at the notch 121. After the mounting plate 60 leaves the interior of the cold water tank 23, as the mounting plate 60 continues to move with the conveyor chain 10, the first part of the deflection component will contact the second part, causing the guide block 701 to disengage from the upper mold 50. Once the guide block 701 is removed, the upper mold 50 slides upward under the elastic action of the first spring 52. At this time, the top of the mold frame 40 is in an open state. When the square column 61 moves to the notch 121, the third gear 64 and the third gear rail 63 are in a meshing state, driving the second gear 62 to rotate. Then, the mounting plate 60 drives the mold frame 40 to rotate together. The casting supported in the mold frame 40 is discharged along the opening at one end of the mold frame 40. The workers can collect the discharged casting. The difficulty of collecting the casting is also relatively small.Furthermore, a discharge conveyor belt 24 is fixedly installed at one end of the water tank 20. The discharge conveyor belt 24 has two horizontal sections and a lifting section fixedly set between the two horizontal sections. The lower horizontal section is located in the cold water tank 23 and below the liquid surface. When the mold frame 40 is tilted and the casting is discharged, the casting will fall into the water in the cold water tank 23 until it falls into the lower horizontal section of the discharge conveyor belt 24. The casting will first come into contact with the cold water, which has a buffering effect on the casting, allowing it to fall smoothly onto the horizontal section of the discharge conveyor belt 24. This prevents damage to the casting caused by it falling onto the discharge conveyor belt 24 on its own. Finally, the discharge conveyor belt 24 transports the casting to a designated location, eliminating the need for workers to collect castings one by one at fixed points. This increases the automation level of the processing device. It requires less labor and has higher die-casting forming efficiency; after the mold frame 40 has discharged the casting, the third gear 64 first separates from the third gear rail 63. At this time, the square column 61 is in an inclined state, and one side of the square column 61 is attached to one end of the limiting frame 12. The square column 61 continues to move with the conveyor chain 10. Under the squeezing action of the limiting frame 12, the square column 61 rotates in the opposite direction until the upper mold 50 is parallel to the horizontal part 101 again; the second gear rail 35 is fixedly installed on the fixing plate 11. The second gear rail 35 is set at the horizontal part 101. When the mounting plate 60 passes over the vertical part 102 and enters the horizontal part 101, the first gear 32 will maintain a meshing state with the second gear rail 35, driving the threaded rod 31 to rotate, so that the lower mold 30 moves upward until the mold frame 40 enters the receiving cavity 301.

[0052] Furthermore, a protruding block 41 is fixedly installed on the other end of the mold frame 40. A sliding hole 411 is provided in the protruding block 41, and a movable rod 42 is slidably arranged in the sliding hole 411. A connecting rod 71 is fixedly installed on the rotating rod 70, and one end of the connecting rod 71 is rotatably connected to the movable rod 42. A protrusion 702 is fixedly installed on the lower surface of the rotating rod 70. The outer edge of the upper mold 50 is located on the outer side of the lower mold 30. A receiving groove 302 for accommodating the protruding block 41 is provided on the lower mold 30. One end of the protruding block 41 is located on the outer side of the edge of the lower mold 30 and on the inner side of the edge of the upper mold 50. When the lower mold 30, the mold frame 40, and the upper mold 50 are in a combined state, one end of the guide block 701 is attached to the stop block 501. When the casting of the mold frame 40 is discharged, the mold frame 40 is tilted by rotation, and the casting slides down under its own weight. After the casting is die-cast and shaped, it is easy to... Even when the mold frame 40 is tilted, the casting cannot easily detach from the mold frame 40. To solve this problem, after the first part of the deflection assembly contacts the second part, the guide block 701 is disengaged from directly above the upper mold 50. After the upper mold 50 moves upward, the rotating rod 70 rotates in the opposite direction under the elastic force of the torsion spring 83 until the protrusion 702 is attached to one end of the protruding block 41. Since one end of the protruding block 41 is located inside the edge of the upper mold 50, the connecting rod 71 can push the movable rod 42 to move a greater distance. One end of the movable rod 42 can enter the mold frame 40 and strike the casting, preventing the casting from sticking tightly to the mold frame 40 and allowing the casting to detach smoothly from the mold frame 40. It should be noted that a rubber head is fixedly installed on one end of the movable rod 42 to prevent the movable rod 42 from striking the casting and causing some damage to the casting. Example

[0053] The specific structures of the first and second parts of the offset assembly are described below. The first part includes a fourth gear 80, a driving bevel gear 81, a driven bevel gear 82, and a fifth gear 85. The second part is a fourth gear rail 84. The driven bevel gear 82 is fixedly mounted on one end of the rotating rod 70. The driving bevel gear 81 is rotatably mounted on the mounting plate 60. The driving bevel gear 81 and the driven bevel gear 82 are in a meshing state. The fourth gear 80 is fixedly connected to the driving bevel gear 81. The fifth gear 85 is also rotatably mounted on the mounting plate 60. The fifth gear 85 is in a meshing state with the fourth gear 80. The fourth gear rail 84 is fixedly mounted on the fixing plate 11. When the fifth gear 85 meshes with the fourth gear rail 84, it can drive the rotating rod 70 to rotate, causing the guide block 701 to disengage from directly above the upper mold 50.

Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention.
