[0002] like Figure 1 The diagram shows an integrated casing product, which is an indispensable key component in modern military equipment. Its performance and quality have a profound impact on the overall performance of military equipment. In addition, it has wide applications in aviation, aerospace and ground power equipment. In its manufacturing process, casting molds are a crucial link.

[0003] like Figure 3 As shown, the casting mold consists of an exhaust box, an upper mold frame, and a lower mold frame from top to bottom. Adjacent molds are typically fitted together using bolts or fasteners. Figure 4 As shown; however, to ensure the tightness and sealing of the installation, many bolts are placed at intervals on the outside of the three components. This presents the problem that the bolts are cumbersome to install and remove each time, and they are also easily lost after removal. Therefore, how to improve the existing casting mold to overcome these problems is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0024] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0026] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0027] One preferred embodiment of this application, such as Figures 1 to 9 As shown, an integrated casing casting mold includes an exhaust box 4, an upper mold frame 5, and a lower mold frame 6 arranged sequentially from top to bottom, and also includes a mounting mechanism, which is installed at intervals on the outside of the upper mold frame 5. The mounting mechanism includes a drive device 9 and a pair of fasteners (generally bolts 7). The fasteners are vertically slidably disposed at the upper and lower ends of the outside of the upper mold frame 5, and the drive device 9 is installed on the upper mold frame 5 and is connected to the fasteners.

[0028] It should be noted that the exhaust box 4 is installed at the top of the upper mold frame 5, and the lower mold frame 6 is installed at the bottom of the upper mold frame 5. Corresponding mounting holes are provided between the three. Since the three have almost the same shape and structure, the mounting holes at the top and bottom of the upper mold frame 5 are exactly corresponding. When assembling the three, the bolts 7 pass through the upper and lower mounting parts of the upper mold frame 5 for fastening. Therefore, both bolts 7 are vertically slidably set on the upper mold frame 5 located in the middle position, and the movement of the bolts 7 is controlled by the drive device 9.

[0029] Understandably, during installation, the drive device 9 can move the bolt 7 and insert it into the corresponding mounting parts on the exhaust box 4 and the lower mold frame 6, and then tighten it with the nut 8, thus assembling the exhaust box 4, the upper mold frame 5, and the lower mold frame 6. During disassembly, the nut 8 is first loosened and removed, and then the drive device 9 drives the bolt 7 to move and store it in the side of the upper mold frame 5.

[0030] Therefore, by movably mounting the two bolts 7 to be installed on the upper mold frame 5 and using the drive device 9 to move the bolts 7 for installation and retraction, the efficiency of bolt 7 assembly and disassembly can be greatly improved. Furthermore, the bolts 7 do not need to be separately removed and stored, significantly reducing the risk of loss. Of course, the disassembled nut 8 can still be screwed onto the bolt 7, thus preventing its loss as well.

[0031] This application does not limit the specific structure of the drive device 9, but the following specific embodiment is provided for reference: like Figure 6 As shown, the drive device 9 includes a pair of connecting rods 902 and a pair of connected drive blocks 901. The drive blocks 901 are horizontally slidably disposed in the middle of the outer side of the upper mold frame 5. The two ends of the connecting rods 902 are respectively hinged to the corresponding fasteners and the drive blocks 901. For ease of installation, a fixing post 12 can be welded to the screw head of the bolt 7, and then the fixing post 12 is hinged to the connecting rod 902.

[0032] Understandably, during installation, moving the drive block 901 towards the upper mold frame 5 causes the drive block 901 to act on the connecting rod 902, which in turn acts on the bolt 7. This allows the two bolts 7 to move away from each other, meaning the upper bolt 7 moves upward through the mounting portion on the exhaust box 4, and the lower bolt 7 moves downward through the mounting portion on the lower mold frame 6. Finally, the bolts are tightened with the nut 8. Figure 7 As shown. And during disassembly, as... Figure 8As shown, first loosen and remove the nut 8, then move the drive block 901 away from the upper mold frame 5 (arrow a). The drive block 901 can then pull the two bolts 7 closer together via the connecting rod 902 (arrow b), thereby causing the two bolts 7 to retract and be stored outside the upper mold frame 5.

[0033] It should be noted that the two drive blocks 901 mentioned above can also be independent of each other, meaning they can independently control their respective bolts 7. This allows for independent operation of bolts 7 at different positions according to actual installation requirements. For example, when only the exhaust box 4 and the upper mold frame 5 need to be connected, only the drive block 901 corresponding to the upper bolt 7 needs to be operated to extend the upper bolt 7 and complete the installation.

[0034] Further optimization, such as Figure 6 As shown, after bolt 7 is installed, i.e., after bolt 7 is fully extended and connected to the corresponding component and tightened, the fastener and connecting rod 902 are aligned in a straight line, which provides a self-locking function in the vertical direction of bolt 7, further improving the stability of bolt 7 installation. It should also be noted that bolt 7 is connected to connecting rod 902 via fixing post 12, which restricts and locks it in the circumferential direction, preventing rotation. Therefore, during tightening, only the nut 8 needs to be rotated, eliminating concerns about bolt 7 rotating during installation and also providing a certain degree of anti-loosening effect.

[0035] Further optimization, such as Figure 5 and Figure 6 As shown, a frame 10 is detachably mounted on the outside of the upper mold frame 5 (e.g., secured with screws), and the drive device 9 and bolts 7 are both mounted on the frame 10. It can be understood that the entire installation mechanism is mounted on the upper mold frame 5 via the frame 10, thus forming an independent unit. This means that no major modifications to the structure of the upper mold frame 5 are required; simply installing the frame 10 into the corresponding position on the upper mold frame 5 is sufficient. This facilitates the assembly of the installation mechanism and also makes subsequent maintenance and replacement easier.

[0036] Based on the above embodiments, the following problem may exist during use: after the bolt 7 retracts, since the drive block 901 is still in a free state, the retracted bolt 7 can easily extend under the action of external force, thereby affecting the subsequent installation and the storage of the upper mold frame 5.

[0037] Therefore, in order to solve the above-mentioned technical problems, such as Figure 6 As shown, the drive block 901 and the frame 10 can be connected by a limiting component 13; when the bolt 7 is retracted, the limiting component 13 can lock the position of the drive block 901, so that the bolt 7 can always remain in the retracted state.

[0038] As a further description of the above embodiments: such as Figure 9 As shown, the limiting component 13 includes a pair of semi-cylinders 1301, which are respectively disposed on the drive block 901 and the frame 10. It can be understood that when the bolt 7 is retracted, the drive block 901 will move until the two semi-cylinders 1301 abut against each other to form a stud, that is, the two semi-cylinders 1301 can be regarded as the stud being "cut" in half from the middle; at this time, the disassembled nut 8 can be tightened on the stud, thus locking the position of the drive block 901.

[0039] Therefore, the disassembled nut 8 can limit the assembled stud, thereby locking the drive block 901; the stud also serves as a storage and placement for the nut 8, achieving two goals at once. Of course, there are many types of existing limiting components 13, such as snap-fit ​​components and magnetic components, which can all achieve the limiting and locking of the drive block 901.

[0040] In a further preferred embodiment, the drive block 901 and the frame 10 are connected and engaged by an elastic element (such as a spring 11). It is understood that when the nut 8 on the stud is loosened and removed, the drive block 901 will be unlocked and then move back to its original position under the elastic force of the spring 11, causing the bolt 7 to extend. Furthermore, the bolt 7 can stably maintain its extended state under the elastic force. This eliminates the need for manual pushing of the drive block 901 during subsequent installation, greatly improving installation efficiency.

[0041] In one embodiment of this application, such as Figure 2 As shown, a cooling element 2 (e.g., a chill) is also provided inside the casting mold. This chill is located in the hot spot area of ​​the casing product 1, away from the gating system. It should be noted that the hot spot area refers to those regions in the casting structure where, due to their large wall thickness, complex shape (such as internal corners or intersections), or poor heat dissipation, the molten metal solidifies slowly and heat is concentrated. Therefore, the hot spot area may be the last area to solidify, easily leading to product quality problems. The chill accelerates the cooling rate of the hot spot area, thus achieving sequential solidification. Furthermore, its distance from the gating system prevents premature solidification of the gating system and blockage of the feeding channels.

[0042] The working principle of this utility model is as follows: Place the prepared lower mold frame 6 smoothly on the molding line plate or workbench, ensuring it is level. Then, place multiple sand cores 3 sequentially into their designated positions on the lower mold frame 6 according to the core-setting order. A dedicated core-setting assembly fixture can be used to ensure accurate positioning of the sand cores 3. Using a dedicated core-setting inspection tool and clamps, check the wall thickness and height of the sand core 3 after each core-setting operation to ensure accuracy. Figure 2As shown. Then close the mold frame 5, and use the drive device 9 to move the bolt 7 and insert it into the lower mold frame 6. Tighten the nut 8 to securely lock the upper and lower mold frames together. Finally, hang the exhaust box 4 on the top of the upper mold frame 5 and tighten it with the nut 8.

[0043] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
