[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In practical use, traditional metal molds are usually not easy to change casting dimensions. When product dimensions need to be adjusted, it may be necessary to redesign and manufacture the metal mold before putting it into production, which increases production costs. This process also slows down the production progress, making it impossible to produce metal products that meet market needs within the specified time, thus greatly reducing the product's market competitiveness.

[0029] In view of this, the present invention provides a metal mold with adjustable casting size, which solves the problem that in actual use, traditional metal molds are usually not easy to change casting size. When product size needs to be adjusted, it may be necessary to redesign and manufacture the metal mold before putting it into production, which increases production costs and slows down the production progress, making it impossible to produce metal products that meet market needs within a specified time, thus greatly reducing the market competitiveness of the product.

[0030] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0031] Example 1: By Figure 1-8 It is known that an adjustable casting size metal mold includes a base plate 1, a support base 2 slidably engaged with the top of the base plate 1, and a vertical plate 3 disposed above one side of the support base 2. The adjustable casting size metal mold also includes a splicing device 4, a fixing device 6, and a protective device 8. The splicing device 4 is disposed between the support base 2 and the vertical plate 3; the fixing device 6 is disposed on both sides of the top of the splicing device 4; and the protective device 8 is disposed below the support base 2. The metal mold adjusts the casting size through the splicing device 4, the fixing device 6 fixes the splicing device 4 after the casting size is adjusted, and the protective device 8 prevents the metal casting being demolded from falling below the support base 2.

[0032] In the specific implementation process, it is worth noting that the top of the base plate 1 is provided with a movable groove, which facilitates the sliding of the support seat 2 on the top of the base plate 1. The cross-section of the support seat 2 is 'T' shaped. The size of the metal mold is adjusted by the splicing device 4. The splicing device 4 is fixed after the casting size is adjusted by the fixing device 6, thus fixing the metal mold after the size adjustment. The protective device 8 can effectively prevent the metal casting that is being demolded from falling below the support seat 2, thus preventing damage to the metal casting product. The material of the splicing device 4 can be selected according to actual needs, as long as it meets the requirements of the work. For example, WC-Co hard alloy material can be used to make the required parts.

[0033] Furthermore, the splicing device 4 includes a first vertical plate 41, a second vertical plate 42, a horizontal plate 43, a connecting rod 44, and a limiting mechanism 45. Two sets of the first vertical plates 41 are respectively located on the front and rear sides between the support base 2 and the upright plate 3. Two sets of the second vertical plates 42 are respectively located on both sides between the two sets of first vertical plates 41, forming a rectangular cavity with the two sets of first vertical plates 41. The horizontal plate 43 is provided corresponding to each first vertical plate 41, and its top groove matches the bottom protrusion of the first vertical plate 41 and the second vertical plate 42. Multiple connecting rods 44 are provided, respectively inserted between two adjacent second vertical plates 42, and between adjacent second vertical plates 42 and horizontal plates 43. The limiting mechanism 45 is located at the bottom of the horizontal plate 43. Through the cooperation of the first vertical plate 41, the second vertical plate 42, the horizontal plate 43, and the connecting rod 44, the size of the metal casting mold can be changed.

[0034] In the specific implementation process, it is worth noting that there are two sets of first vertical plates 41, located on the front and rear sides between the support base 2 and the vertical plate 3. Each set has four plates, and each has a square protrusion at the bottom. It can be understood that the number of first vertical plates 41 can be increased or decreased according to actual needs, as long as the work is met. The two first vertical plates 41 in the middle have a rectangular locking block on one side and a rectangular locking groove identical to the rectangular locking block on the other side. The surfaces of the locking block and the locking groove are provided with screw holes, so that the two first vertical plates 41 can be fixed with screws. The two first vertical plates 41 on both sides have a locking groove on the side that can accommodate half of the connecting rod 44. One of the first vertical plates 41 has a rectangular... The first vertical plate 41 has a rectangular slot on one side and no rectangular slot on the other. Three screws are used to fix the four first vertical plates 41 together. Two sets of second vertical plates 42 are located between the support base 2, the vertical plate 3, and the two first vertical plates 41. Each set has four plates, with a rectangular protrusion at the bottom and a threaded groove at the top. It is understood that the number of second vertical plates 42 can be increased or decreased as needed to meet operational requirements. Each of the eight second vertical plates 42 has slots on both sides that can accommodate half a connecting rod 44. The connecting rod 44 is used to fix the four second vertical plates 42 together. Four horizontal plates 43 are provided, with the two middle horizontal plates 43 having tops... The front and rear sides of the assembly have slots identical to the bottom protrusions of the first vertical plate 41. Both outer walls of the two horizontal plates 43 have slots capable of accommodating half a connecting rod 44. Only one corresponding side of the side wall of the two horizontal plates 43 has a slot capable of accommodating half a connecting rod 44. Compared to the two middle horizontal plates 43, the top of each has four additional slots to accommodate the rectangular protrusions at the bottom of the second vertical plate 42. A connecting plate is provided between the first vertical plate 41, the second vertical plate 42, and the horizontal plates 43. The connecting plate secures the first vertical plate 41, the second vertical plate 42, and the horizontal plates 43 together with four screws to prevent the bottom of the assembly device 4 from detaching during casting. Multiple connecting rods 44 are provided, and the cross-section of each connecting rod 44 is 'H' shaped. Understandably, the number of connecting rods 44 can be reduced or increased according to actual needs, as long as the work is met. There are two types of connecting rods 44: one is placed vertically with a shorter length, and the other is placed horizontally with a longer length. They serve the same purpose: to connect the two parts together. Sealing gaskets are provided between the above-mentioned components. The material of the sealing gaskets can be selected according to actual needs, as long as the work is met. For example, it can be a ceramic fiber high-temperature resistant sealing material. Through the cooperation of the first vertical plate 41, the second vertical plate 42, the horizontal plate 43 and the connecting rods 44, the size of the casting metal mold can be adjusted according to actual production needs, thereby improving the production flexibility of the adjustable casting size metal mold.

[0035] Furthermore, the limiting mechanism 45 includes a fixed slider 451, a base 453, and a sliding groove 452. The fixed slider 451 is fixedly connected to the bottom of the horizontal plate 43; the base 453 is attached to the bottom of the horizontal plate 43; the sliding groove 452 is opened at the top of the base 453 and is slidably engaged with the outer wall of the fixed slider 451; wherein, through the cooperation of the fixed slider 451 and the sliding groove 452, the base 453 is fixed to the bottom of the horizontal plate 43.

[0036] In the specific implementation process, it is worth noting that there are multiple fixed sliders 451. It can be understood that the number of fixed sliders 451 is proportional to the number of horizontal plates 43. Each horizontal plate 43 has four fixed sliders 451 fixedly connected to its bottom. The base 453 supports the splicing device 4 at the top. There are four sliding slots 452 on the base 453. It can be understood that the size of the base 453 and the length of the sliding slots 452 can be determined according to the number of horizontal plates 43. Multiple bases 453 of different sizes can be produced in advance for convenient use. One side of the sliding slot 452 is open to facilitate the entry of the fixed sliders 451. The end of the sliding slot 452 can be sealed with a high-temperature resistant sealing plug. Sealing gaskets are provided between the above components. The material of the sealing gaskets can be selected according to actual needs as long as they meet the working requirements. For example, it can be a ceramic fiber high-temperature resistant sealing material, which improves the structural stability of the metal mold with adjustable casting size.

[0037] Specifically, when the adjustable casting size metal mold is needed, the worker places the adjustable casting size metal mold in the designated position, connects the external power supply of the first electric telescopic rod 13, and starts the first electric telescopic rod 13. The first electric telescopic rod 13 drives the support base 2 to move, and the support base 2 drives the splicing device 4 above it to move until the splicing device 4 moves directly below the casting liquid. The casting liquid is then poured into the interior of the splicing device 4. After standing for a period of time until the surface solidifies, the first electric telescopic rod 13 is started again. The first electric telescopic rod 13 drives the support base 2 to move, and the support base 2 drives the splicing device 4 above it to move until it returns to its initial position. The first electric telescopic rod 13 then stops working. At this time, the electric slide 31 and The external power supply to the electric slider 311 is activated, and the electric slide rail 31 and electric slider 311 are started. Through the cooperation of the electric slide rail 31 and electric slider 311, the splicing device 4 is driven to move downward until the splicing device 4 enters the interior of the cooling box 7. At this time, the electric slide rail 31 and electric slider 311 stop working. It can be understood that the cooling box 7 needs to be filled with coolant before use. After cooling for a period of time, the electric slide rail 31 and electric slider 311 are restarted, and they drive the splicing device 4 to rise and return to the initial position. At this time, the casting liquid inside the splicing device 4 has solidified. At the same time, the operator removes the sealing plug at the end of the sliding groove 452 with tools and removes the connecting rod 44 located between the two horizontal plates 43 in the middle. The operator connects the external power supply to the second electric telescopic rod 81 and starts it. The second electric telescopic rod 81 moves the connecting column 82, which in turn moves the protective plate 83 until the protective plate 83 completely blocks the through groove 21. The second electric telescopic rod 81 then stops working. After this, the operator connects the power supply to the external hydraulic pump of the hydraulic cylinder 32 and starts it. The hydraulic cylinder 32 moves the vertical plate 3, which in turn moves the connecting seat 5 via the electric slide 31 and the electric slider 311. The connecting seat 5 moves the splicing device 4 via the fixing device 6. At this point, the splicing device 4 is divided into two parts. The casting product inside the splicing device 4 is partially demolded, while the other part remains in the other part of the splicing device 4. On the side, the worker uses tools to remove it, and then puts each part back in place. When it is necessary to change the size of the metal casting mold, first, the worker rotates the fixing screw on the top of the fixing block 61 clockwise, so that the fixing screw is away from the inner wall of the second vertical plate 42. Then, the worker rotates the bolt 63 clockwise. The bolt 63 moves the lower side wall of the fixing block 61 away from the groove on the upper side wall of the second vertical plate 42 through the threaded hole 62. The other seven are handled in the same way. At this time, the splicing device 4 is completely detached from the support base 2. It can be understood that when it is necessary to change different metal molds, the above operation can be used to change the metal mold. The worker removes the splicing device 4 and places it on the workbench, and removes the sealing plug on one side of the sliding groove 452 on the top of the base 453.Remove the connecting plate and the four screws on it. Repeat this process for the remaining screws on the connecting plates. At this point, the base 453 can detach from the bottom of the horizontal plate 43. Since the horizontal plate 43 is connected to the first vertical plate 41 and the second vertical plate 42 via a plug-in connection, the horizontal plate 43 can also be directly removed. Then, remove the connecting rod 44 between the horizontal plates 43, thus disassembling the horizontal plate 43. Next, remove the connecting rod 44 between the first vertical plate 41 and the second vertical plate 42, disassembling the second vertical plate 42. Finally, rotate the screws on the outer wall of the first vertical plate 41 clockwise. After removing all the screws, the first vertical plate 41 disassembles. Through the above operations, the splicing device 4 is completely disassembled into individual components. Finally, select suitable components for assembly according to actual needs. By reversing the above process, the casting dimensions of the metal mold can be adjusted.

[0038] Example 2: From Figure 1-8 It can be seen that connecting seats 5 are provided on both sides of the outer wall of the two sets of second vertical plates 42 that are far apart. A fixing plate 52 is fixedly connected to the top of the connecting seat 5. The top of the connecting seat 5 is slidably engaged with the limiting slider 51. The fixing device 6 includes a fixing block 61, a threaded hole 62 and a bolt 63. The fixing block 61 is fixedly connected to the top of the limiting slider 51 and inserted into the groove of the side wall of the second vertical plate 42. The threaded hole 62 is opened on the outer wall of the fixing block 61 that is far away from the second vertical plate 42. The bolt 63 is threadedly connected to the inner wall of the threaded hole 62, and the outer wall is rotatably connected to the inner wall of the fixing plate 52 through a sealed bearing. The fixing block 61 fixes the spliced ​​device 4 after it is spliced ​​by the cooperation of the bolt 63 and the threaded hole 62.

[0039] In the specific implementation process, it is worth noting that the connecting seat 5 is rectangular, and the top is provided with a limiting groove that can cooperate with the sliding limit slider 51 to slide. One side of the limiting groove is open. The limiting slider 51 is limited by screws and a limiting plate. The fixing block 61 is C-shaped, and the top is threaded with screws. The fixing block 61 is fixed to the second vertical plate 42 by screws. One side of the fixing block 61 is provided with a threaded hole 62. The fixing block 61 can be moved by the cooperation of bolts 63 and threaded holes 62. The assembled splicing device 4 can be fixed by the fixing block 61 and the screws on its top. Through the cooperation of the above components, the purpose of replacing the metal mold can be achieved, and the application range of the adjustable casting size metal mold is expanded.

[0040] Furthermore, a through groove 21 is formed on the surface of the support base 2, and a loading groove 22 is formed on the inner wall of the through groove 21 near the side of the upright plate 3. The protective device 8 includes a second electric telescopic rod 81, a connecting column 82, and a protective plate 83. The second electric telescopic rod 81 is fixedly connected to the bottom side of the support base 2; the connecting column 82 is fixedly connected to the output end of the second electric telescopic rod 81 and is movably connected to the bottom of the loading groove 22; the protective plate 83 is fixedly connected to the top of the connecting column 82 and inserted into the inner wall of the loading groove 22. The second electric telescopic rod 81 drives the connecting column 82 to move, and the through groove 21 is closed by the cooperation of the connecting column 82 and the protective plate 83.

[0041] In the specific implementation process, it is worth noting that the through groove 21 is set directly below the splicing device 4 and is rectangular in shape. The loading groove 22 is opened on one side of the through groove 21 and has a 'T' shaped cross section, which facilitates the sliding of the connecting column 82 and the protective plate 83 inside it. The protective plate 83 is rectangular and can completely close the through groove 21. The model of the second electric telescopic rod 81 is selected according to actual needs and only needs to meet the working requirements. Through the cooperation of the above components, it is possible to prevent the cast finished product from falling to other places through the through groove 21.

[0042] Furthermore, electric slide grooves 31 are installed on the side of the support base 2 opposite to the vertical plate 3. Electric sliders 311 are slidably engaged on the inner walls of the two electric slide grooves 31. The outer walls of the two electric sliders 311 away from the electric slide grooves 31 are respectively fixedly connected to the outer walls of the two connecting bases 5 away from the outer walls of the two sets of second vertical plates 42.

[0043] In the specific implementation process, it is worth noting that the electric slide 31 and the electric slider 311 are used together. The models of the electric slide 31 and the electric slider 311 can be selected according to actual needs. Through the cooperation of the electric slide 31 and the electric slider 311, the working efficiency of the metal mold with adjustable casting size is improved.

[0044] Furthermore, support feet 11 are installed at the four corners of the bottom of the base plate 1, and a first support plate 12 is fixedly connected to the top of the base plate 1 on the side away from the support seat 2. A first electric telescopic rod 13 is fixedly connected to the side wall of the first support plate 12, and the output end of the first electric telescopic rod 13 is fixedly connected to the outer wall of the support seat 2.

[0045] In the specific implementation process, it is worth noting that the support foot 11 provides overall support for the adjustable casting size metal mold, and the first support plate 12 provides support for the first electric telescopic rod 13. The model of the first electric telescopic rod 13 is selected according to actual needs, as long as it meets the working requirements. Through the cooperation of the above components, the adjustable casting size metal mold is moved away from the casting equipment, making it easier for workers to observe the solidification of the casting liquid, thereby improving the safety of using the adjustable casting size metal mold.

[0046] Furthermore, a second support plate 33 is fixedly connected to the top of the support base 2 on the side away from the vertical plate 3, and a hydraulic cylinder 32 is fixedly connected to the outer wall of the second support plate 33. The output end of the hydraulic cylinder 32 is fixedly connected to the outer wall of the vertical plate 3 on the side away from the second vertical plate 42.

[0047] In the specific implementation process, it is worth noting that the second support plate 33 supports the hydraulic cylinder 32. The model of the hydraulic cylinder 32 can be selected according to actual needs. Through the cooperation of the above components, the purpose of semi-automatic demolding of the metal mold with adjustable casting size is achieved.

[0048] Furthermore, a cooling box 7 is provided below the through groove 21. A drain pipe 71 is connected to the bottom of the cooling box 7. Support columns 72 are fixedly connected to the four corners of the bottom of the cooling box 7. The bottom of the four support columns 72 is fixedly connected to the top of the base plate 1 on the side near the support seat 2.

[0049] In the specific implementation process, it is worth noting that the cooling box 7 is rectangular in shape and contains coolant. The coolant can be added from the top of the cooling box 7, and the drain pipe 71 connected to the bottom of the cooling box 7 can drain the coolant. The support column 72 supports the cooling box 7. Through the cooperation of the above components, the cooling speed of the casting liquid inside the adjustable casting size metal mold is accelerated. Of course, since the high temperature of the molten metal inside the mold causes the mold temperature to rise as well, the temperature of the coolant inside the cooling box 7 should be reasonably controlled and should not be too low. This will achieve uniform and relatively rapid cooling of the mold and the workpiece, and avoid defects such as deformation and cracks caused by thermal stress due to excessively low temperature, thus ensuring the performance of the workpiece and the durability of the mold.

[0050] Specifically, the combination of fixing block 61, threaded hole 62, and bolt 63 enables the replacement of metal molds, expanding the application range of adjustable casting size metal molds. The combination of second electric telescopic rod 81, connecting column 82, and protective plate 83 prevents finished castings from falling to other places through through groove 21. The combination of electric slide 31 and electric slider 311 improves the working efficiency of adjustable casting size metal molds. The combination of first support plate 12 and first electric telescopic rod 13 keeps the adjustable casting size metal mold away from the casting equipment, facilitating workers to observe the solidification of the casting liquid and improving the safety of using the adjustable casting size metal mold.
