Description
Technical Field
[0001] This invention relates to the field of core shooting machine technology, and particularly to a mold for a core shooting machine, which is especially suitable for the automated production process of sand cores in intelligent casting islands. Background Technology
[0002] In the foundry industry, the core shooter is a key piece of equipment for producing sand cores. It injects high-pressure core sand into the forming cavity of a mold, and after the core sand solidifies, it forms a sand core of the desired shape, which is then used for the forming and processing of castings. With the continuous optimization of the structure of casting products, some sand core products require a "mountain"-shaped connecting rod structure at the bottom to meet the requirements of subsequent assembly and mechanical properties. This places higher demands on the structural design of the core shooter mold and the ease of demolding—it must ensure the accurate forming of the "mountain"-shaped connecting rod structure, and it must also ensure that the sand core product can be smoothly removed from the mold after forming, avoiding damage to the sand core or reduced production efficiency due to poor demolding.
[0003] Traditional core shooting machine molds mostly adopt a simple upper and lower mold splitting structure, which can meet the basic demolding requirements for sand core products without complex protrusions at the bottom. However, for sand core products with "mountain"-shaped connecting rods at the bottom, this type of mold has obvious defects: the "mountain"-shaped connecting rod structure will form multiple contact surfaces with the mold cavity, and the sand core is prone to jamming with the cavity during demolding. In addition, traditional molds lack targeted mold splitting and ejection mechanisms, and operators need to use external tools to assist in demolding, which not only increases the difficulty of operation, but also easily causes damage to the "mountain"-shaped connecting rod structure, resulting in a decrease in the sand core product qualification rate and a longer single sand core production cycle. It is difficult to meet the batch and high-efficiency sand core production requirements in intelligent casting islands. Summary of the Invention
[0004] To address the aforementioned problems, the present invention provides a mold for a core shooting machine.
[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a mold for a core shooting machine, comprising a lower frame, an upper frame, a mounting platform, a lifting mechanism, a module, a control component, and a lifting mechanism; the upper frame is fixed to the top of the lower frame, the mounting platform is disposed between the upper frame and the lower frame, and the lifting mechanism is disposed on the upper frame and used to control the lifting of the mounting platform; the module comprises a lower fixed mold, a first lower moving mold, a second lower moving mold, a first upper moving mold, a second upper moving mold, and a core mold, wherein the top of the first upper moving mold and the top of the second upper moving mold are jointly provided with It is equipped with a sand-shooting pipe; a through hole is provided on the lower fixed mold for the installation of the first lower moving mold and the second lower moving mold. The lower fixed mold, the first lower moving mold, the second lower moving mold, the first upper moving mold, the second upper moving mold and the core mold together form the molding cavity for making the sand core product; the control component is set on the upper frame and is used to control the first upper moving mold and the second upper moving mold to move closer or further apart; the lifting mechanism is set on the top of the mounting platform and is used to control the first lower moving mold and the second lower moving mold to separate from each other during the lifting process of the mounting platform, and simultaneously lift the core mold and the sand core product.
[0006] By adopting the above technical solution, the shapes of the lower fixed mold, first lower moving mold, second lower moving mold, first upper moving mold, second upper moving mold, and core mold are designed according to the sand core product. These parts together form the molding cavity. High-pressure core sand enters the molding cavity through the sand injection pipe, forming a sand core product with a "mountain"-shaped connecting rod at the bottom. During demolding, the operator can use control components to control the first and second upper moving molds to move away from each other. A lifting mechanism can control the mounting platform to rise, simultaneously lifting the core mold and the sand core product. Simultaneously, the lifting mechanism drives the first and second lower moving molds to separate during the platform's ascent, facilitating the demolding of the sand core product with the "mountain"-shaped connecting rod. After demolding, the core mold is returned to its original position, and the reverse operation resets the first and second lower moving molds, first and second upper moving molds, for the next sand core product production. This changes the structural design of traditional technology, improves the production efficiency of sand core products, and is more suitable for the continuous production rhythm of intelligent casting islands.
[0007] Furthermore, the lifting mechanism includes a lifting assembly and a separation assembly. The lifting assembly includes a push rod fixed to the top of the mounting platform. Multiple push rods are provided. A first vertical hole is provided through the lower fixed mold for the push rod on the side of the first lower moving mold to pass through. A second vertical hole is also provided on the lower fixed mold for the push rod on the side of the second lower moving mold away from the first lower moving mold to pass through. The sides of the first lower moving mold and the second lower moving mold that are close to each other are provided with grooves that cooperate with the "mountain"-shaped connecting rod at the bottom of the sand core product. The separation assembly is provided on the mounting platform and controls the first lower moving mold and the second lower moving mold to move to the sides respectively during the lifting of the mounting platform.
[0008] By adopting the above technical solution, when the first upper moving mold and the second upper moving mold are opened, during the process of the lifting mechanism controlling the installation platform to rise, the push rods and the separation components are raised synchronously with the installation platform. Multiple push rods cooperate to gradually lift the core mold and the sand core product sleeved on its outside. During this process, the separation components control the first lower moving mold and the second lower moving mold to move to both sides respectively, thereby loosening the "mountain"-shaped connecting rod structure of the sand core product so that the workers can take the sand core product out from the end of the core mold. Subsequently, the workers need to control the core mold, the first lower moving mold, the second lower moving mold, the first upper moving mold and the second upper moving mold to reset in order to remake the sand core product.
[0009] Furthermore, the separation assembly includes a first connecting unit and a second connecting unit. The first connecting unit includes a first connecting seat fixed to the top of the mounting platform and a first diagonal brace hinged to the top of the first connecting seat. The upper end of the first diagonal brace is fixed to the bottom of the first lower moving mold. The second connecting unit includes a second connecting seat fixed to the top of the mounting platform and a second diagonal brace hinged to the top of the second connecting seat. The upper end of the second diagonal brace is fixed to the bottom of the second lower moving mold, and the second diagonal brace and the first diagonal brace are distributed intersectingly.
[0010] By adopting the above technical solution, during the lifting process of the mounting platform, the first connecting seat, the first diagonal brace, the second connecting seat, the second diagonal brace, the first lower moving mold, and the second lower moving mold all rise synchronously. Since the second diagonal brace and the first diagonal brace are distributed in a cross pattern, when the first lower moving mold and the second lower moving mold are separated from the lower fixed mold, the first lower moving mold and the second lower moving mold tilt to both sides under their own gravity until the "mountain"-shaped connecting rod structure at the bottom of the sand core product is completely exposed. At this time, the workers can easily demold the sand core product from the core mold.
[0011] Furthermore, the sidewalls on both sides of the through hole are inclined, and the distance between the two sidewalls decreases from top to bottom. The sidewalls of the first lower moving mold and the second lower moving mold that are far apart from each other are respectively matched with the sidewalls on both sides of the through hole.
[0012] By adopting the above technical solution, during the process of the worker controlling the resetting of the first and second lower moving molds, the sides of the first and second lower moving molds that are far apart from each other cooperate with the side walls on both sides of the through hole and promote the resetting of the first and second lower moving molds. When the first and second lower moving molds are completely reset, the groove on the first lower moving mold cooperates with the groove on the second lower moving mold and just forms the cavity of the "mountain" shaped connecting rod structure at the bottom of the sand core product.
[0013] Furthermore, a through slot is provided through the upper frame, the side wall of the through slot is located near the edge of the lower fixed mold, a central block is fixed to the inner wall of the through slot, and a first movable hole for the first diagonal brace and a second movable hole for the second diagonal brace are provided through the central block.
[0014] By adopting the above technical solution, the setting of the first movable hole and the second movable hole on the center block plays a certain buffering role on the movement of the first diagonal brace and the movement of the second diagonal brace, respectively, ensuring the smoothness of the separation process between the first lower moving mold and the second lower moving mold.
[0015] Furthermore, the lifting mechanism includes a guide assembly and a drive assembly. The guide assembly includes multiple guide posts fixed to the bottom of the upper frame. The guide posts pass through the mounting platform and are slidably engaged. Each guide post is fitted with a nut that is threadedly connected to it. The nut is located at the bottom of the mounting platform and adjacent to the lower end of the guide post. The drive assembly includes an electric push rod fixed to the bottom of the mounting platform and an abutment rod fixed to the lower end of the electric push rod.
[0016] By adopting the above technical solution, after the staff starts the electric push rod, the abutment rod at the lower end of the electric push rod touches the ground, which allows the installation platform to be raised. The guide column ensures the stability of the installation platform during the lifting process, so as to facilitate the smooth demolding of the sand core product.
[0017] Furthermore, the control assembly includes a first frame, a first cylinder, a second frame, and a second cylinder. The first frame is fixed to the upper frame, the first cylinder is fixed to the first frame, and the piston rod end of the first cylinder is fixed to the first upper moving mold. The second frame is fixed to the side of the upper frame away from the first frame, the second cylinder is fixed to the second frame, and the piston rod end of the second cylinder is fixed to the second upper moving mold.
[0018] By adopting the above technical solution, the staff can control the first upper moving mold and the second upper moving mold to move closer or further apart through the first cylinder and the second cylinder, so as to ensure the smooth production of sand core products.
[0019] Furthermore, the mold of the core shooting machine also includes a limiting component, which includes a top plate and a limiting block; the top plate is located above the first upper moving mold and the second upper moving mold, and can be raised and lowered in the vertical direction, and the top plate is provided with a clearance hole for the insertion of the sand shooting tube; the limiting block is fixed to the bottom of the top plate, and there are two of them, with limiting grooves provided on the side of the first upper moving mold and the second upper moving mold that are far apart from each other, and the two limiting grooves are respectively engaged with the two limiting blocks.
[0020] By adopting the above technical solution, the top plate can be raised and lowered by a lifting structure, such as a commonly used structure like a robotic arm. When the first upper moving mold and the second upper moving mold are closed, the two limiting blocks at the bottom of the top plate limit the first upper moving mold and the second upper moving mold respectively, ensuring the stability of the first upper moving mold and the second upper moving mold during the production of sand core products.
[0021] Furthermore, the first upper moving mold, the second upper moving mold, and the lower fixed mold are all provided with a first groove and a forming groove. The first groove is inserted into one end of the core mold, and the forming groove is connected to the first groove. An end block is fixed on the top of the upper frame, and a second groove is provided on the side of the end block near the lower fixed mold, which is inserted into the other end of the core mold.
[0022] By adopting the above technical solutions, the stable progress of the sand core product molding process was ensured.
[0023] Furthermore, a third frame is fixed to the top of the upper frame, and a third cylinder is fixed to the third frame. The piston rod end of the third cylinder is fixed to the side of the end block away from the core mold.
[0024] By adopting the above technical solution, the staff can control the movement of the end block through the third cylinder, which is conducive to the smooth demolding of the product.
[0025] In summary, the present invention has the following beneficial effects:
[0026] 1. In this application, the shapes of the lower fixed mold, the first lower moving mold, the second lower moving mold, the first upper moving mold, the second upper moving mold, and the core mold are designed according to the sand core product. These parts together form a molding cavity. High-pressure core sand enters the molding cavity from the sand injection pipe, forming a sand core product with a "mountain"-shaped connecting rod at the bottom. During demolding, the operator can use a control component to control the first and second upper moving molds to move away from each other. A lifting mechanism can control the mounting platform to rise and simultaneously lift the core mold and the sand core product. Simultaneously, the lifting mechanism drives the first and second lower moving molds to separate during the platform's ascent, facilitating the demolding of the sand core product with the "mountain"-shaped connecting rod. After demolding, the core mold is returned to its original position, and the reverse operation resets the first and second lower moving molds, the first and second upper moving molds, and the second upper moving mold, allowing for the production of the next sand core product. This changes the structural design of traditional technology, improves the production efficiency of sand core products, and is more suitable for the continuous production rhythm of intelligent casting islands.
[0027] 2. In this application, during the process of the mounting platform rising, the first connecting seat, the first diagonal brace, the second connecting seat, the second diagonal brace, the first lower moving mold, and the second lower moving mold all rise synchronously. Since the second diagonal brace and the first diagonal brace are distributed in a cross pattern, when the first lower moving mold and the second lower moving mold are separated from the lower fixed mold, the first lower moving mold and the second lower moving mold tilt to both sides under their own gravity until the "mountain"-shaped connecting rod structure at the bottom of the sand core product is completely exposed. At this time, the workers can easily demold the sand core product from the core mold. Attached Figure Description

Detailed Implementation
[0044] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0045] like Figure 1-15As shown in the embodiment of this application, a mold for a core shooting machine is disclosed, including a lower frame 1, an upper frame 2, a mounting platform 3, a lifting mechanism 4, a module 5, a control component 6, and a lifting mechanism 7; the upper frame 2 is fixed to the top of the lower frame 1, the mounting platform 3 is disposed between the upper frame 2 and the lower frame 1, and the lifting mechanism 4 is disposed on the upper frame 2 and used to control the lifting of the mounting platform 3; the module 5 includes a lower fixed mold 51, a first lower moving mold 52, a second lower moving mold 53, a first upper moving mold 54, a second upper moving mold 55, and a core mold 56, with a sand-shooting pipe 8 jointly disposed on the top of the first upper moving mold 54 and the top of the second upper moving mold 55; the lower fixed mold A through hole 511 is provided on the lower fixed mold 51 for mounting the first lower moving mold 52 and the second lower moving mold 53. The lower fixed mold 51, the first lower moving mold 52, the second lower moving mold 53, the first upper moving mold 54, the second upper moving mold 55 and the core mold 56 together form the molding cavity for making the sand core product 9. The control component 6 is provided on the upper frame 2 and is used to control the first upper moving mold 54 and the second upper moving mold 55 to move closer or further apart from each other. The lifting mechanism 7 is provided on the top of the mounting platform 3 and is used to control the first lower moving mold 52 and the second lower moving mold 53 to separate from each other during the lifting process with the mounting platform 3, and at the same time lift the core mold 56 and the sand core product 9.
[0046] The shapes of the lower fixed mold 51, the first lower moving mold 52, the second lower moving mold 53, the first upper moving mold 54, the second upper moving mold 55, and the core mold 56 are designed according to the sand core product 9. These parts together form the molding cavity. After the high-pressure core sand enters the molding cavity from the sand injection pipe 8, it forms the sand core product 9 with a "mountain"-shaped connecting rod at the bottom. During demolding, the operator can use the control component 6 to control the first upper moving mold 54 and the second upper moving mold 55 to move away from each other. The lifting mechanism 4 can control the mounting platform 3 to rise and simultaneously lift the core mold 56 and the sand core product 9. At the same time, the lifting mechanism 7 drives the first lower moving mold 52 and the second lower moving mold 53 to separate from each other during the lifting of the mounting platform 3, so as to facilitate the demolding of the sand core product 9 with the "mountain"-shaped connecting rod. After demolding, the core mold 56 is returned to its original position. The reverse operation can reset the first lower moving mold 52, the second lower moving mold 53, the first upper moving mold 54, and the second upper moving mold 55 so that the next sand core product 9 can be made. This changes the structural design in the traditional technology, improves the production efficiency of the sand core product 9, and is more suitable for the continuous production rhythm of the intelligent casting island.
[0047] The lifting mechanism 7 includes a lifting component 71 and a separating component 72. The lifting component 71 includes a push rod 711 fixed to the top of the mounting platform 3. Multiple push rods 711 are provided. A first vertical hole 512 is provided through the lower fixed mold 51 for the push rod 711 on one side of the first lower moving mold 52 to pass through. A second vertical hole 513 is also provided on the lower fixed mold 51 for the push rod 711 on the side of the second lower moving mold 53 away from the first lower moving mold 52 to pass through. The first lower moving mold 52 and the second lower moving mold 53 are provided with a groove 522 on the side that is close to each other, which cooperates with the "mountain"-shaped connecting rod at the bottom of the sand core product 9. The separating component 72 is provided on the mounting platform 3 and controls the first lower moving mold 52 and the second lower moving mold 53 to move to both sides respectively during the lifting of the mounting platform 3.
[0048] When the first upper moving mold 54 and the second upper moving mold 55 are opened, during the process of the lifting mechanism 4 controlling the installation platform 3 to rise, the push rod 711 and the separation component 72 are raised synchronously with the installation platform 3. Multiple push rods 711 cooperate and gradually lift the core mold 56 and the sand core product 9 sleeved on its outside. During this process, the separation component 72 controls the first lower moving mold 52 and the second lower moving mold 53 to move to both sides respectively, thereby loosening the "mountain"-shaped connecting rod structure of the sand core product 9 so that the workers can take the sand core product 9 out of the end of the core mold 56. Subsequently, the workers need to control the core mold 56, the first lower moving mold 52, the second lower moving mold 53, the first upper moving mold 54 and the second upper moving mold 55 to reset in order to remake the sand core product 9.
[0049] The separation assembly 72 includes a first connecting unit 721 and a second connecting unit 722. The first connecting unit 721 includes a first connecting seat 7211 fixed to the top of the mounting platform 3 and a first diagonal support rod 7212 hinged to the top of the first connecting seat 7211. The upper end of the first diagonal support rod 7212 is fixed to the bottom of the first lower moving mold 52. The second connecting unit 722 includes a second connecting seat 7221 fixed to the top of the mounting platform 3 and a second diagonal support rod 7222 hinged to the top of the second connecting seat 7221. The upper end of the second diagonal support rod 7222 is fixed to the bottom of the second lower moving mold 53, and the second diagonal support rod 7222 and the first diagonal support rod 7212 are distributed crosswise.
[0050] During the ascent of the mounting platform 3, the first connecting seat 7211, the first diagonal brace 7212, the second connecting seat 7221, the second diagonal brace 7222, the first lower moving mold 52, and the second lower moving mold 53 all rise synchronously. Since the second diagonal brace 7222 and the first diagonal brace 7212 are intersected, when the first lower moving mold 52 and the second lower moving mold 53 are separated from the lower fixed mold 51, the first lower moving mold 52 and the second lower moving mold 53 tilt to both sides under their own gravity until the "mountain"-shaped connecting rod structure at the bottom of the sand core product 9 is completely exposed. At this time, the workers can easily demold the sand core product 9 from the core mold 56.
[0051] The sidewalls on both sides of the through hole 511 are inclined, and the distance between the two sidewalls decreases from top to bottom. The sidewalls of the first lower moving mold 52 and the second lower moving mold 53, which are far apart from each other, respectively cooperate with the sidewalls on both sides of the through hole 511.
[0052] During the process of the staff controlling the resetting of the first lower moving mold 52 and the second lower moving mold 53, the sides of the first lower moving mold 52 and the second lower moving mold 53 that are far apart from each other respectively cooperate with the side walls on both sides of the through hole 511 and promote the resetting of the first lower moving mold 52 and the second lower moving mold 53. When the first lower moving mold 52 and the second lower moving mold 53 are completely reset, the groove 522 on the first lower moving mold 52 and the groove 522 on the second lower moving mold 53 cooperate and just form the cavity of the bottom "mountain" shaped connecting rod structure of the sand core product 9.
[0053] A through groove 21 is provided through the upper frame 2. The side wall of the through groove 21 is located near the edge of the lower fixed mold 51. A center block 10 is fixed to the inner wall of the through groove 21. A first movable hole 101 for the first diagonal brace 7212 to move and a second movable hole 102 for the second diagonal brace 7222 to move are provided through the center block 10.
[0054] The first movable hole 101 and the second movable hole 102 on the center block 10 provide a certain buffering effect on the movement of the first inclined support rod 7212 and the second inclined support rod 7222, respectively, ensuring the smoothness of the separation process between the first lower moving mold 52 and the second lower moving mold 53.
[0055] The lifting mechanism 4 includes a guide assembly 41 and a drive assembly 42. The guide assembly 41 includes multiple guide posts 411 fixed to the bottom of the upper frame 2. The guide posts 411 pass through the mounting platform 3 and slide together. Each guide post 411 is fitted with a nut 412 threadedly connected to it. The nut 412 is located at the bottom of the mounting platform 3 and adjacent to the lower end of the guide post 411. The drive assembly 42 includes an electric push rod 421 fixed to the bottom of the mounting platform 3 and an abutment rod 422 fixed to the lower end of the electric push rod 421. After the operator starts the electric push rod 421, the abutment rod 422 at the lower end of the electric push rod 421 touches the ground, which allows the mounting platform 3 to be raised. The guide posts 411 ensure the stability of the mounting platform 3 during the lifting process, so as to facilitate the smooth demolding of the sand core product 9.
[0056] The control assembly 6 includes a first frame 61, a first cylinder 62, a second frame 63, and a second cylinder 64. The first frame 61 is fixed to the upper frame 2, and the first cylinder 62 is fixed to the first frame 61, with the piston rod end of the first cylinder 62 fixed to the first upper moving mold 54. The second frame 63 is fixed to the side of the upper frame 2 away from the first frame 61, and the second cylinder 64 is fixed to the second frame 63, with the piston rod end of the second cylinder 64 fixed to the second upper moving mold 55. Operators can control the first upper moving mold 54 and the second upper moving mold 55 to move closer or further apart using the first cylinder 62 and the second cylinder 64 to ensure the smooth production of the sand core product 9.
[0057] The core shooting machine mold also includes a limiting component 11, which includes a top plate 111 and limiting blocks 112. The top plate 111 is located above the first upper moving mold 54 and the second upper moving mold 55 and can be raised and lowered vertically. The top plate 111 is provided with a clearance hole 1111 for inserting the sand shooting tube 8. The limiting blocks 112 are fixed to the bottom of the top plate 111, and there are two of them. The sides of the first upper moving mold 54 and the second upper moving mold 55 that are far apart from each other are provided with limiting grooves 12. The two limiting grooves 12 are respectively engaged with the two limiting blocks 112. The top plate 111 can be raised and lowered by a lifting structure, such as a commonly used structure like a robot. When the first upper moving mold 54 and the second upper moving mold 55 are closed, the two limiting blocks 112 at the bottom of the top plate 111 limit the first upper moving mold 54 and the second upper moving mold 55 respectively, ensuring the stability of the first upper moving mold 54 and the second upper moving mold 55 during the production of the sand core product 9.
[0058] The first upper moving mold 54, the second upper moving mold 55, and the lower fixed mold 51 are all provided with a first groove 13 and a forming groove 14. The first groove 13 is inserted into one end of the core mold 56, and the forming groove 14 is connected to the first groove 13. An end block 15 is fixed on the top of the upper frame 2. The end block 15 is provided with a second groove 151 on the side near the lower fixed mold 51, which is inserted into the other end of the core mold 56, to ensure the stable operation of the sand core product 9 forming process.
[0059] A third frame 16 is fixed to the top of the upper frame 2, and a third cylinder 161 is fixed to the third frame 16.
