[0009] Based on the above technical scheme, the utility model further can make improvement as follows.

[0010] Further, the straight guide rod penetrates the bottom seat and is connected and fixed with the lower die seat.

[0011] The beneficial effects of the above further scheme are:

[0012] The straight guide rod, as an important component connecting the bottom seat and the lower die seat, penetrates and is fixed, which greatly enhances the overall structural stability of the mold. This design enables the mold to maintain stable shape and size when subjected to the huge pressure and impact force during the pressure casting process, thereby ensuring the precision and quality of the pressure castings. The design of the straight guide rod helps to accurately control the relative position between the lower die seat and the upper die seat. During the mold closing process, the straight guide rod can guide and limit the movement direction of the lower die seat, ensuring that the upper die seat and the lower die seat can accurately and quickly fit. The design of the straight guide rod penetrating the bottom seat and the lower die seat simplifies the installation process of the mold. During mold assembly, the straight guide rod only needs to be inserted into the corresponding holes of the bottom seat and the lower die seat and fixed. This design not only saves installation time, but also reduces installation difficulty. At the same time, since the straight guide rod is easy to disassemble and replace, it also facilitates the daily maintenance and maintenance of the mold.

[0013] Further, the bottom seat is provided with an inclined guide rod, and the side pressing plate is limitedly installed on the bottom seat through the inclined guide rod.

[0014] The beneficial effects of the above further scheme are:

[0015] The design of the inclined guide rod enables better guiding of the mold during opening and closing. When the mold needs to be opened or closed, the inclined guide rod can guide the side pressure plate to move along a predetermined trajectory, ensuring that the relative position between the side pressure plate and the base remains unchanged. This guiding action not only improves the accuracy of mold opening and closing, but also enhances the stability of the mold during opening and closing. As an important component connecting the base and the side pressure plate, the design of the inclined guide rod can disperse the stress and impact force generated during die casting. Through the transmission and dispersion of the inclined guide rod, the various components of the mold can collectively withstand pressure, thereby improving the overall strength and durability of the mold. The design of the inclined guide rod simplifies the assembly and disassembly process of the mold. During assembly, the side pressure plate only needs to be pushed into the base along the direction of the inclined guide rod and fixed. Similarly, during disassembly, the side pressure plate only needs to be removed from the base along the direction of the inclined guide rod. This design not only saves assembly and disassembly time, but also reduces the complexity of operation.

[0016] Further, the spring pushes the push plate, and then the lower mold base and the upper mold base are tightly attached, and after the lower mold base and the upper mold base are attached, they are fixed by a bolt.

[0017] The beneficial effects of the above further scheme are:

[0018] The pushing force of the spring can ensure that the push plate always exerts a certain pressure on the lower mold base, so that the lower mold base and the upper mold base can be tightly attached when the mold is closed. This tight attachment helps to reduce the gap inside the mold and prevent metal liquid from leaking during die casting, thereby improving the quality and precision of the die casting. The tight attachment of the lower mold base and the upper mold base achieved by the spring pushing the push plate helps to improve the sealing of the mold. This sealing can prevent external gas or impurities from entering the mold, affecting the solidification process of the metal liquid and the quality of the die casting. The pushing force of the spring not only tightly attaches the lower mold base and the upper mold base, but also enhances the stability of the mold during die casting. This stability helps to reduce deformation and damage of the mold under high pressure and high temperature, prolonging the service life of the mold. After the lower mold base and the upper mold base are tightly attached, they are locked and fixed by a bolt, which simplifies the locking process of the mold. Compared with traditional locking methods, bolt locking is faster, more convenient, and the locking force is more uniform, which helps to improve the locking effect and safety of the mold.

[0019] Further, the upper cover plate is inlaid with a pressing block, and the upper cover plate is tightly fixed by the pressing block.

[0020] The beneficial effects of the above further scheme are:

[0021] The design of the pressing block enables the upper cover plate to be closely attached to the side pressing plate, thereby enhancing the overall stability and sealing performance of the mold. This close attachment helps to prevent leakage of the molten metal during the die casting process, ensuring the quality and precision of the die castings. By pressing the side pressing plate with the pressing block, the movement and deformation of the side pressing plate during the opening and closing of the mold can be reduced, thereby reducing the risk of wear and damage to the side pressing plate. This design prolongs the service life of the mold and reduces maintenance and replacement costs.

[0022] Further, the side edges of the side pressing plate are provided with protrusions, and the side fixing plate is provided with corresponding clamping grooves, and the side fixing plate is clamped to the side pressing plate through the clamping grooves and the protrusions.

[0023] The beneficial effects of the above further scheme are:

[0024] The clamping design of the protrusions and the clamping grooves ensures the accurate alignment between the side pressing plate and the side fixing plate. This design reduces errors during assembly and improves the overall assembly precision of the mold, thereby ensuring the size and shape precision of the die castings. The clamping structure of the protrusions and the clamping grooves can enhance the stability of the mold during the die casting process. Through clamping fixation, the connection between the side pressing plate and the side fixing plate is more firm, which can resist the huge pressure and impact force generated during the die casting process, preventing the mold from deforming or being damaged.

[0025] The utility model provides a kind of thin-walled piece die casting die. It has the following beneficial effects:

[0026] The mold is carefully designed and assembled by bottom plate, support, base, upper cover plate and other components, ensuring the compactness and stability of the overall structure. This design not only improves the stability of the mold during operation, but also enables the mold to withstand greater pressure and impact force, prolonging the service life.

[0027] The design of the spring and the push plate enables the lower die seat to be closely attached to the upper die seat, and is locked and fixed by bolts, ensuring the precision and stability of the mold when closing. At the same time, the elastic effect of the spring also makes the mold more flexible and smooth when opening, reducing the difficulty and labor intensity of operation.

[0028] The side fixing plate and the side pressing plate are clamped by the clamping grooves and the protrusions, achieving the pressing and fixing of the side pressing plate. This design not only simplifies the installation process, but also improves the reliability and stability of the fixation. At the same time, the design of the inclined guide rod further restricts the movement of the side pressing plate, enhancing the overall stability of the mold.

[0029] The design of the pressing block on the upper cover plate enables the upper cover plate to further press and fix the side pressing plate through the pressing block. This design not only enhances the sealing performance of the mold, but also improves the pressure resistance of the mold in high-pressure environment.

[0030] The pouring opening on the upper cover plate is communicated with the forming cavity of the upper die seat, so that the molten metal can be smoothly injected into the mold, and the workpiece is shaped by the cooperation of the upper die seat and the core plate. This design not only improves the efficiency of pouring and forming, but also ensures the shape and size accuracy of the workpiece.

[0031] The upper cover plate is installed on the base by the insertion rod, which not only simplifies the installation process of the mold, but also improves the stability and safety of the mold during use. BRIEF DESCRIPTION OF DRAWINGS

[0042] Embodiment one

[0043] The invention discloses a thin-walled part die-casting die, which comprises a bottom plate 9, a support 1 arranged on the bottom plate 9, a base 2 supported and installed on the bottom plate 9 through the support 1, a lower die seat 11 installed on the base 2, a core plate 12 arranged on the lower die seat 11, an upper cover plate 5 installed above the base 2, an upper die seat 13 installed on the lower surface of the upper cover plate 5, a connecting plate 8 installed on the bottom plate 9, a spring 10 installed on the connecting plate 8, a push plate 802 installed on the connecting plate 8 through the spring 10, the spring 10 pushes the push plate 802, and then the lower die seat 11 and the upper die seat 13 are tightly attached, and after the lower die seat 11 and the upper die seat 13 are attached, they are locked and fixed through bolts, the pushing force of the spring 10 can ensure that the push plate 802 always applies a certain pressure to the lower die seat 11, so that the lower die seat 11 and the upper die seat 13 can be tightly attached when the mold is closed. This tight attachment helps to reduce the gap inside the mold, prevent metal liquid from leaking during the die-casting process, and thus improve the quality and precision of the die-casting parts. The tight attachment of the lower die seat 11 and the upper die seat 13 achieved by the spring 10 pushing the push plate 802 helps to improve the sealing performance of the mold. This sealing performance can prevent external gas or impurities from entering the mold, affecting the solidification process of the metal liquid and the quality of the die-casting parts. The pushing force of the spring 10 not only makes the lower die seat 11 and the upper die seat 13 tightly attached, but also enhances the stability of the mold during the die-casting process. This stability helps to reduce the deformation and damage of the mold under high pressure and high temperature environment, prolonging the service life of the mold. After the lower die seat 11 and the upper die seat 13 are tightly attached, they are locked and fixed through bolts, which simplifies the locking process of the mold. Compared with the traditional locking method, the bolt locking is faster, more convenient, and the locking force is more uniform, which helps to improve the locking effect and safety of the mold. The push plate 802 is provided with a straight guide rod 801, the push plate 802 is connected with the lower die seat 11 through the straight guide rod 801, the straight guide rod 801 penetrates the base 2 and is connected and fixed with the lower die seat 11, and the straight guide rod 801 is an important component connecting the base 2 and the lower die seat 11. Its penetrating and fixed design greatly enhances the overall structural stability of the mold. This design makes the mold maintain stable shape and size when bearing the great pressure and impact force during the die-casting process, thereby ensuring the precision and quality of the die-casting parts. The design of the straight guide rod 801 helps to accurately control the relative position between the lower die seat 11 and the upper die seat 13. During the mold closing process, the straight guide rod 801 can guide and limit the movement direction of the lower die seat 11, ensuring that the upper die seat 13 and the lower die seat 11 can be accurately and quickly attached. The design of the straight guide rod 801 penetrating the base 2 and the lower die seat 11 simplifies the installation process of the mold. When the mold is assembled, the straight guide rod 801 only needs to be inserted into the corresponding holes of the base 2 and the lower die seat 11 and fixed. This design not only saves the installation time, but also reduces the installation difficulty.Meanwhile, since the straight guide rod 801 is easy to disassemble and replace, it also facilitates the daily maintenance and maintenance of the mold. The base 2 is provided with a side fixing plate 7 on both sides. The base 2 is provided with a side pressing plate 3 through the side fixing plate 7. The side edge of the side pressing plate 3 is provided with a protrusion. The side fixing plate 7 is provided with a clamping groove corresponding to the protrusion. The side fixing plate 7 is clamped with the protrusion through the clamping groove to press and fix the side pressing plate 3. The clamping design of the protrusion and the clamping groove can ensure the accurate positioning between the side pressing plate 3 and the side fixing plate 7. This design reduces the error in the assembly process and improves the overall assembly accuracy of the mold, thereby ensuring the size and shape accuracy of the die casting. The clamping structure of the protrusion and the clamping groove can enhance the stability of the mold during the die casting process. Through clamping, the connection between the side pressing plate 3 and the side fixing plate 7 is more firm, which can resist the huge pressure and impact force generated during the die casting process, prevent the mold from deforming or damaging, and the upper cover plate 5 is embedded with a pressing block 6. The upper cover plate 5 is pressed and fixed to the side pressing plate 3 through the pressing block 6. The design of the pressing block 6 makes the upper cover plate 5 more closely fit the side pressing plate 3, thereby enhancing the overall stability and sealing of the mold. This close fit helps to prevent metal liquid from leaking during the die casting process, ensuring the quality and accuracy of the die casting. Through the pressing block 6, the side pressing plate 3 is pressed and fixed, which can reduce the movement and deformation of the side pressing plate 3 during the opening and closing of the mold, thereby reducing the wear and damage risk of the side pressing plate 3. This design prolongs the service life of the mold and reduces the maintenance and replacement cost. The base 2 is provided with an inclined guide rod 301. The side pressing plate 3 is limitingly installed on the base 2 through the inclined guide rod 301. The design of the inclined guide rod 301 makes the mold better guided during opening and closing. When the mold needs to be opened and closed, the inclined guide rod 301 can guide the side pressing plate 3 to move along the predetermined track, ensuring that the relative position between the side pressing plate 3 and the base 2 remains unchanged. This guiding action not only improves the accuracy of the mold opening and closing, but also enhances the stability of the mold during the opening and closing process. The inclined guide rod 301, as an important component connecting the base 2 and the side pressing plate 3, can disperse the stress and impact force generated during the die casting process. Through the transmission and dispersion of the inclined guide rod 301, the components of the mold can jointly bear the pressure, thereby improving the overall strength and durability of the mold. The design of the inclined guide rod 301 simplifies the assembly and disassembly process of the mold. During assembly, the side pressing plate 3 only needs to be pushed into the base 2 along the direction of the inclined guide rod 301 and fixed. Similarly, during disassembly, the side pressing plate 3 only needs to be disassembled from the base 2 along the direction of the inclined guide rod 301. This design not only saves the assembly and disassembly time, but also reduces the complexity of the operation.

[0044] Example two

[0045] In order to facilitate the shaping of the workpiece by the cooperation of the upper mold base 13 and the core plate 12, for example, Figures 1 to 4As shown, the utility model still includes: the upper cover plate 5 is installed with the pouring opening 4, the upper die base 13 is provided with the forming cavity 1301, the pouring opening 4 is communicated with the forming cavity 1301, the upper cover plate 5 is equipped with the plug rod 501, the upper cover plate 5 is installed on the base 2 through the plug rod 501 limiting, the upper die base 13 is mutually matched with the core plate 12 and is shaped to workpiece.

[0046] Working principle:

[0047] In initial state, the mould is in open state, and the upper die base 13 is separated from the lower die base 11. When needing die casting, first, the upper cover plate 5 and the upper die base 13 on it are moved downward by external power (such as hydraulic cylinder or pneumatic cylinder). The upper die base 13 will make the lower die base 11 receive certain pre-tightening force by the push plate 802 connected with the spring 10 during moving downward, to ensure that the upper die base 13 and the lower die base 11 can be closely attached when the mould is closed. At the same time, the side pressing plate 3 will also gradually approach and press tightly on the lower die base 11 under the guidance of the inclined guide rod 301, and is fixed by the clamping mode of the clamping groove and the protruding block. When the upper die base 13 and the lower die base 11 are completely attached and fixed by the bolt locking, the mould closing process is completed.

[0048] After the mould closing is completed, the molten metal liquid is injected into the forming cavity 1301 of the mould through the pouring opening 4. The metal liquid fills the forming cavity 1301 of the upper die base 13 under the action of gravity and pressure. After the metal liquid is injected into the forming cavity 1301, the mould inside starts to cool. With the temperature reduction, the metal liquid gradually solidifies into the shape of the required thin-walled part. During the die casting process, the mould will be subjected to high temperature and high pressure, but since the mould is made of high-strength alloy steel material and has undergone precise machining and heat treatment, it can withstand such harsh working environment.
