Description

Technical Field

[0001] The invention belongs to the technical field of demoulding of intelligent casting islands, and in particular relates to a large casting directional demoulding device for an intelligent casting island. Background Art

[0002] The intelligent casting island is a highly integrated automated production system in the modern manufacturing industry. It combines advanced information technology, robotics, sensor technology and intelligent manufacturing concepts to improve the efficiency, precision and flexibility of casting production. The specific working method is to use the automatic batching system to automatically weigh and mix the raw materials according to the formula, and put them into the melting furnace: heat the raw materials to a molten state, use an industrial robot to pour the molten metal into the mold to achieve precise pouring, and finally use the directional demolding device to ensure that the casting is smoothly ejected from the mold to avoid damage. The molding demolding in the existing technology generally uses a cylinder to push the workpiece out, which is easy to cause pulling damage to the workpiece.

[0003] The existing Chinese patent document with publication number CN118699292A proposes an intelligent casting island for rapid production of pneumatic valve actuator housings, wherein an inner mold is arranged inside a support frame, and a first outer mold and a second outer mold are arranged on the left and right sides of the inner mold respectively, and casting ports are arranged above the first outer mold and the second outer mold; a first demolding mechanism is used to drive the first outer mold and the second outer mold to separate from the molded housing at the same time; a second demolding mechanism is provided on the inner mold, and the second demolding mechanism is used to drive the first protrusion and the second protrusion to separate from the molded housing, but the inner mold and the outer mold act on the same casting at the same time, which increases the risk of the casting getting stuck during the demolding process, especially in the case of complex shapes or large sizes. Once the inner mold gets stuck, it will have a very large impact on the casting.

[0004] Therefore, the present invention proposes a large-scale casting directional demolding device for an intelligent casting island, which solves the problem that the ejection mechanism is prone to jamming when demolding in the prior art, which affects the casting. The inner mold core is improved by liquid filling and matched with an external push demolding component. The inner mold contraction and outer mold expansion sliding demolding are used to replace the traditional direct ejection demolding, so as to minimize the impact of mold jamming on the casting during the demolding process.

[0038] For example, see Figures 1 to 18The present invention provides a technical solution: a large-scale casting directional demoulding device for an intelligent casting island, comprising an intelligent casting island body 1, a conveying device 11 is arranged on one side of the intelligent casting island body 1, a melting injection device 3 is arranged on the other side of the intelligent casting island body 1, an injection head 31 is arranged at the extrusion end of the melting injection device 3, a feeding device 2 is arranged at one end of the intelligent casting island body 1, a cooling wind tower 4 is arranged below the melting injection device 3, a cooling wind duct 41 is fixedly installed at the output pipe end of the cooling wind tower 4, a demoulding component 5 is arranged at the other end of the intelligent casting island body 1, an outer mold 7 is arranged on one side of the demoulding component 5, a casting head component 6 is arranged on one side of the outer mold 7, the demoulding component 5 comprises a directional demoulding frame 51, a demoulding push rod 52 and a demoulding driving frame 53, the casting head component 6 comprises a moving frame 61, a telescopic rod 62 and a casting head 63, an inner mold core 71 is arranged inside the outer mold 7, a limiting rod 511 is fixedly installed on one side of the demoulding driving frame 53, and the demoulding driving frame 53 is slidably installed on the directional demoulding frame 51 The demoulding push rod 52 is fixedly mounted on one end of the directional demoulding frame 51, and the output end of the demoulding push rod 52 is fixedly connected to the surface of one side of the demoulding driving frame 53. The other side surface of the demoulding driving frame 53 is fixedly mounted with an ejector ring 531, and the ejector ring 531 is slidably mounted on the inside of the outer mold 7. The inner surface of the ejector ring 531 contacts the outer surface of the inner mold core 71, and the outer surface of the ejector ring 531 is hingedly mounted with a sliding demoulding key sheet 533. The inner side wall of the outer mold 7 is provided with a sliding demoulding key sheet 533. The sliding demoulding key sheet 533 is provided with an oblique sliding groove adapted to the sliding demoulding key sheet 533, a joint ring 532 is provided on one side of the sliding demoulding key sheet 533, the inner wall of the joint ring 532 is provided with a sliding hole adapted to the limiting rod 511, the side wall of the joint ring 532 is provided with a movable groove adapted to the sliding demoulding key sheet 533, a spring connecting rod 5321 is movably installed inside the joint ring 532, one end of the spring connecting rod 5321 is movably connected to one end of the sliding demoulding key sheet 533, and a sealing head 5322 is provided on the inner surface of the joint ring 532;In this embodiment, first, the demoulding push rod 52 works to drive the demoulding driving frame 53 to slide to the first extreme position inside the directional demoulding frame 51. At this time, the ejector ring 531 is at the rear end of the outer mold 7 close to the demoulding assembly 5, and the joint ring 532 is at the front end of the outer mold 7. The sliding demoulding key piece 533 fits with the oblique groove on the inner side of the outer mold 7. The position between the outer mold 7 and the inner mold core 71 is the casting molding area. The movable frame 61 is pushed by the telescopic rod 62 to make the casting head 63 engage with the inner side of the joint ring 532. The feeding device 2 cooperates with the melting injection device 3 to feed the inside of the casting head 63 through the injection head 31 and the casting port 632. The casting head 63 makes the molten material evenly fill the casting molding area between the outer mold 7 and the inner mold core 71. The cooling wind tower 4 is cooled by the cooling air duct 41 to the outer mold 7. The cooling air is inputted to accelerate the cooling and forming of the workpiece. After the casting is formed, the telescopic rod 62 drives the moving frame 61 to withdraw to the other side of the conveying device 11. The demoulding push rod 52 is started to push the demoulding driving frame 53 to slide inside the directional demoulding frame 51. At this time, the ejection ring 531, the sliding demoulding key piece 533 and the joint ring 532 are ejected. As the sliding demoulding key piece 533 is ejected, the internal oblique groove of the outer mold 7 gradually widens. The sliding demoulding key piece 533 is driven by the spring connecting rod 5321 to gradually expand and detach from the surface of the casting, so that the ejection ring 531 drives the casting to be demoulded and gradually detaches from the casting, avoiding damage to the casting caused by the impact force during the ejection process. The progressive demoulding method helps to maintain the quality of the casting surface, reduce surface defects such as scratches and indentations, and ensure the good appearance of the casting. ;

[0039] For example 2, please refer to Figures 1 to 18On the basis of the first embodiment, the present embodiment further proposes that a deformation mold piece 711 is provided on the side wall of the inner mold core 71, a water injection cavity 713 is fixedly installed inside the inner mold core 71, a water injection hollow piston 714 is slidably installed inside the water injection cavity 713, a drainage ring pipe 712 is fixedly installed on one side surface of the inner mold core 71, a spring limiting push rod 7111 is fixedly installed on the inner side surface of the deformation mold piece 711, a side wall of the deformation mold piece 711 that passes through the water injection cavity 713, a drainage groove 7131 is opened in the middle of the side wall of the water injection cavity 713, an extrusion sheet 7112 is fixedly installed on one end of the deformation mold piece 711, and the water injection hollow piston 714 is slidably installed inside the water injection cavity 713. The inner wall of one end is provided with a slide groove adapted to the extrusion sheet 7112, one end of the water injection hollow piston 714 is provided with a water injection port 7141, and the outer surface of the other end of the water injection hollow piston 714 is provided with a sealing plug 7142 adapted to the discharge groove 7131. A circulating water tank 8 is provided at the bottom of the intelligent casting island body 1, a booster pump 81 is provided on one side of the circulating water tank 8, a drain pipe 82 is fixedly installed on the other side of the booster pump 81, and a water inlet pipe 83 is fixedly installed on the output pipe of the booster pump 81. The upper end of the booster pump 81 is fixedly connected to the inner side wall of the drainage ring pipe 712, and the upper end of the water inlet pipe 83 is fixedly connected to the inner wall of the water injection port 7141;In this embodiment, the booster pump 81 first injects cooling water into the water injection hollow piston 714 through the drain pipe 82 and the water injection port 7141. As the water injection increases, the water injection hollow piston 714 slides inside the water injection cavity 713 until the sealing plug 7142 is stuck in the discharge groove 7131. This process needs to be monitored by installing a water pressure sensor inside the water injection hollow piston 714 or a position sensor inside the discharge groove 7131. Both the water pressure sensor and the position sensor are mature and feasible. The prior art will not be described in detail in this embodiment. When the sealing plug 7142 is inserted into the drain groove 7131, all the cooling water is temporarily stored in the water injection cavity 713. Moreover, because the extrusion sheet 7112 is squeezed and expanded when the water injection hollow piston 714 moves, the deformation die sheet 711 is lifted up with the cooperation of the extrusion sheet 7112, which is convenient for the casting of the casting. It is worth noting that the deformation die sheet 711 can be made of a material with good high temperature resistance and ductility, and is connected to the inner mold core 71 as a whole. After the workpiece is cast, the booster pump 81 continues to output The cooling water is poured into the water injection hollow piston 714. At this time, the water injection hollow piston 714 continues to move to break through the middle position of the extrusion sheet 7112. The sealing plug 7142 cancels the blockage of the drain groove 7131, so that the cooling water stored in the water injection cavity 713 flows into the space between the water injection cavity 713 and the deformation die sheet 711, accelerating the cooling of the casting. At this time, the cooling water refluxes under the cooperation of the internal pump of the circulating water tank 8 and the drainage pipe 82 and the drainage ring pipe 712. After the casting is completely cooled, the booster pump 81 stops, but the internal pump of the circulating water tank 8 continues to pump the cooling water inside the inner mold core 71. The water is refluxed and extracted. With the change of water pressure and the spring rebound effect of the spring limit push rod 7111, the water injection hollow piston 714 is reversely squeezed back to the other side of the discharge groove 7131. At this time, the circulating water tank 8 stops working. With the inward contraction and extrusion process of the extrusion sheet 7112, the deformation mold sheet 711 also contracts and separates from the inner surface of the casting. This process helps to break the adhesion between the casting and the inner mold core 71, making demoulding smoother and reducing the required demoulding force, which also achieves the effect of facilitating demoulding of the casting. ;

[0040] For example 3, please refer to Figures 1 to 18On the basis of the second embodiment, the present embodiment further proposes that the telescopic rod 62 is fixedly installed below one end of the main body 1 of the intelligent casting island close to the feeding device 2, the output end of the telescopic rod 62 is fixedly connected to one side surface of the mobile frame 61, the casting head 63 is fixedly installed on the other side surface of the mobile frame 61, the side wall of the mobile frame 61 is provided with a sliding hole adapted to the limit rod 511, the side surface of the casting head 63 close to the outer mold 7 is fixedly installed with a joint sealing ring 631 adapted to the sealing head 5322, the side surface of the joint sealing ring 631 is provided with a connecting notch 6311, and the side wall of the casting head 63 is fixedly installed with a casting port 632 adapted to the injection head 31 ; In this embodiment, the movable frame 61 is pushed by the telescopic rod 62 to make the casting head 63 engage with the inner side of the joint ring 532, and the joint sealing ring 631 engages with the sealing head 5322 to ensure the sealing of the casting feed. The feeding device 2 cooperates with the melting injection device 3 to feed the inside of the casting head 63 through the injection head 31 and the casting port 632. The connecting groove 6311 has a certain micro-groove at the front end to connect the front end of the workpiece after the workpiece is formed. As the casting head 63 leaves, it can drive the workpiece to move, further improving the smoothness of demoulding. The movable frame 61 and the joint ring 532 are limited by the limit rod 511 during movement, indicating the accuracy of directional demoulding and casting.

[0041] Example 4, please refer to Figures 1 to 18On the basis of the third embodiment, the present embodiment further proposes that an auxiliary demoulding head 72 is fixedly installed on the inner mold core 71, and a conical limiting frame 721 is fixedly installed on the side surface of the auxiliary demoulding head 72, a threaded rod assembly 722 is arranged inside the conical limiting frame 721, and a movable plate 723 is threadedly connected to the outer surface of the threaded rod of the threaded rod assembly 722, and an auxiliary demoulding frame 7231 is movably installed on the outer surface of the movable plate 723, and a limiting groove matched with the auxiliary demoulding frame 7231 is provided on the side wall of the conical limiting frame 721, and a supporting pad 7232 is movably installed on the upper side of the auxiliary demoulding frame 7231, and an anti-slip pad 72321 is fixedly installed on the upper side of the supporting pad 7232, and a sliding ball 72322 is movably installed on the inner wall of the supporting pad 7232; in the present embodiment, as the casting head 63 leaves and the top During the demoulding process, the ejection ring 531, the joint ring 532 and the sliding demoulding key piece 533 move as a whole. The threaded rod assembly 722 inside the conical limit frame 721 first cooperates to move the movable plate 723 to the rearmost position. At this time, the auxiliary demoulding frame 7231 is maximized, and the support pad 7232 lifts the inner side of the casting. The anti-slip pad 72321 can increase the stability and anti-slip effect until the casting is completely separated from the ejection ring 531 and the sliding demoulding key piece 533 of the joint ring 532. At this time, the threaded rod assembly 722 cooperates to move the movable plate 723 in the opposite direction to the front. At this time, the auxiliary demoulding frame 7231 is stretched and contracted. At this time, the casting directly slides off to the top of the conveying equipment 11 under the cooperation of gravity and the sliding ball 72322. The subsequent conveying equipment 11 can directly unload the material, making the demoulding process simpler and more convenient.

[0042] For example 5, please refer to Figures 1 to 18On the basis of the fourth embodiment, this embodiment further proposes a demoulding method for a large casting directional demoulding device for an intelligent casting island, comprising the following steps: Step 1, first, the demoulding push rod 52 drives the demoulding driving frame 53 to slide to the first limit position inside the directional demoulding frame 51, so that the ejector ring 531 is at the rear end of the outer mold 7 close to the demoulding assembly 5, the joint ring 532 is at the front end of the outer mold 7, the sliding demoulding key piece 533 is matched with the oblique groove on the inner side of the outer mold 7, and the mobile frame 61 is pushed by the telescopic rod 62 to make the casting head 63 engage with the inner side of the joint ring 532; Step 2, the booster pump 81 injects cooling water into the water injection hollow piston 714 through the drain pipe 82 and the water injection port 7141, As more water is injected, the water injection hollow piston 714 slides inside the water injection cavity 713 until the sealing plug 7142 is stuck in the drain groove 7131. When the sealing plug 7142 is stuck in the drain groove 7131, all the cooling water is temporarily stored in the water injection cavity 713. Because the extrusion sheet 7112 is squeezed and expanded when the water injection hollow piston 714 moves, the deformed mold sheet 711 is lifted up with the cooperation of the extrusion sheet 7112, and the casting molding area is completed; step three, the feeding equipment 2 cooperates with the melting injection equipment 3 to feed the casting head 63 through the injection head 31 and the casting port 632. The casting head 63 makes the molten material evenly fill the casting molding area between the outer mold 7 and the inner mold core 71, and the cooling wind tower 4 is passed. The supercooling air duct 41 inputs cooling air to the top of the outer mold 7 to accelerate the cooling and forming of the workpiece, and the booster pump 81 continues to input cooling water. At this time, the water injection hollow piston 714 continues to move to break through the middle position of the extrusion plate 7112, and the sealing plug 7142 cancels the blockage of the drain groove 7131, so that the cooling water stored in the water injection cavity 713 is all poured into the space between the water injection cavity 713 and the deformation mold piece 711, accelerating the cooling of the casting. At this time, the cooling water refluxes with the cooperation of the internal pump of the circulating water tank 8 and the drain pipe 82 and the drain ring pipe 712. After the casting is completely cooled, the booster pump 81 stops; step four, after casting, the internal pump of the circulating water tank 8 continues to reflux and extract the cooling water inside the inner mold core 71. As the water pressure changes The spring rebound effect of the spring limit push rod 7111 causes the water injection hollow piston 714 to be reversely squeezed back to the other side of the discharge groove 7131. As the extrusion sheet 7112 shrinks and extrudes inward, the deformed mold sheet 711 also shrinks and separates from the inner surface of the casting. The telescopic rod 62 drives the moving frame 61 to withdraw to the other side of the conveying device 11. The demoulding push rod 52 is started to drive the demoulding driving frame 53 to slide inside the directional demoulding frame 51. At this time, the ejection ring 531, the sliding demoulding key sheet 533 and the joint ring 532 are ejected. The sliding demoulding key sheet 533 is gradually expanded and separated from the surface of the casting under the drive of the spring connecting rod 5321, so that the ejection ring 531 drives the casting to be demoulded and gradually separates from the casting.Step 5: The threaded rod assembly 722 inside the conical limit frame 721 first cooperates to move the movable plate 723 to the rear, at which time the auxiliary demoulding frame 7231 is maximized, the support pad 7232 lifts the inner side of the casting, and the anti-skid pad 72321 can increase the stability and anti-skid effect until the casting is completely separated from the ejection ring 531 and the sliding demoulding key sheet 533 of the joint ring 532. At this time, the threaded rod assembly 722 cooperates to move the movable plate 723 in the reverse direction to the front, at which time the auxiliary demoulding frame 7231 is stretched and contracted, and at this time the casting directly slides off to the top of the conveying device 11 under the cooperation of gravity and the sliding ball 72322, and the subsequent conveying device 11 can directly unload the material. ;
