Description

Technical Field

[0001] This utility model relates to the field of precision casting technology, and in particular to a mold shell horizontal hanging tool. Background Technology

[0002] In the precision casting industry, mold shell preparation is a crucial step. During mold shell preparation, a suspension system is typically used for conveying and drying. Currently, the mainstream hanging method is to vertically suspend the mold shell, which is suitable for most standard mold shells.

[0003] However, in actual production, some mold shells with special structures or sizes can suffer from problems such as internal structural deformation, uneven coating distribution, or insufficient drying when vertically suspended. For these mold shells, horizontal suspension is a better choice. In existing technologies, if horizontal suspension is required, it is usually necessary to customize a special fixed lifting device for the mold shell of a specific size and weight. Each set of special lifting devices can only correspond to one type of mold shell. When the production line needs to change the type of mold shell, the lifting device must be changed at the same time, resulting in poor versatility. Simple beam suspension may cause the mold shell to tilt, rotate, or even slip during lifting and drying, posing a safety hazard. Utility Model Content

[0004] Based on the above analysis, this utility model relates to a horizontal hanging fixture for mold shells, which solves the problems that existing hanging fixtures are only suitable for vertical hanging, have poor versatility or poor safety, and realize the safe and stable horizontal hanging of mold shells without changing the main structure of the existing suspension chain, and can adapt to the needs of hanging mold shells of different sizes and weights.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] On one hand, the mold shell horizontal hanging fixture includes a suspension bracket, a hanging shaft, and an adjustable hanging beam mechanism. The adjustable hanging beam mechanism is suspended below the suspension bracket via the hanging shaft. The adjustable hanging beam mechanism includes a crossbeam, a pin, and multiple grooves. Multiple grooves are provided on the crossbeam along its length. The pin is disposed in the groove, and the radius of the pin is smaller than the radius of the groove.

[0007] Furthermore, it also includes hooks and limiting blocks. The hooks are located below the adjustable hanging beam mechanism for suspending the mold shell; the pin passes through the upper part of the hook; the limiting blocks are located on both sides of the hook, and the limiting blocks are used to limit the lateral movement range of the hook on the crossbeam. Furthermore, a spirit level is provided on the crossbeam.

[0008] Furthermore, the surface of the groove is provided with a wear-resistant coating.

[0009] Furthermore, the groove is divided into a coarse adjustment section groove and a fine adjustment section groove; the groove spacing between adjacent coarse adjustment section grooves is greater than the groove spacing between adjacent fine adjustment section grooves.

[0010] Furthermore, the coarse adjustment groove is located at both ends of the crossbeam, and the fine adjustment groove is located in the middle of the crossbeam.

[0011] Furthermore, an inclined guide surface is provided between adjacent grooves.

[0012] Furthermore, the inclined guide surface is an arc-shaped inclined surface, and the inclined guide surface is tangent to the arc surface of the groove to form a smooth and continuous sliding surface.

[0013] Furthermore, a positioning groove is provided at the bottom of the coarse adjustment section groove; the radius of the positioning groove is larger than the radius of the pin.

[0014] Furthermore, the hanging shaft is a T-shaped hanging shaft.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0016] (1) By utilizing the fit between the pin and the groove, operators can quickly adjust the hook spacing without tools, allowing one set of fixtures to accommodate mold shells of various widths. Since the pin radius is smaller than the groove radius, the pin can move between adjacent grooves for rapid adjustment; simultaneously, the arc-shaped structure of the groove effectively limits the pin's circumferential movement, preventing it from sliding axially along the beam due to unexpected external forces during hoisting, thus ensuring the stability and safety of the hoisting process. Based on the adjustable hanging beam mechanism, operators can fine-tune the positions of the two hooks to ensure the mold shell is always in a horizontal hanging state, achieving horizontal hoisting of the mold shell.

[0017] (2) By setting the grooves into coarse adjustment section grooves and fine adjustment section grooves with different groove spacing, a highly efficient operation process of "first quick positioning, then fine adjustment" is achieved. This design takes into account both adjustment efficiency and adjustment accuracy, and is particularly suitable for the working conditions of frequent mold shell changes on the production line.

Detailed Implementation

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0027] Example 1

[0028] A type of horizontally hanging tooling for mold shells, such as Figure 1 and Figure 2 As shown, it includes a suspension bracket 1, a hanging shaft 2, an adjustable hanging beam mechanism 3, a hook 4, and a limit block 5.

[0029] The catenary hanger 1 is a fixed support structure. The adjustable hanging beam mechanism 3 is suspended below the catenary hanger 1 via the hanging shaft 2. The hooks 4 are used in pairs and are symmetrically connected to the lower part of the adjustable hanging beam mechanism 3 to support the mold shell. Each hook 4 has a bent hook at the bottom for hanging the mold shell, and the upper part of each hook 4 is movably connected to the adjustable hanging beam mechanism 3. Limiting blocks 5 are provided on both sides of the hook 4 and are fixedly connected to the hook 4 to limit the lateral movement range of the hook 4 on the adjustable hanging beam mechanism 3 and prevent the hook 4 from slipping to the sides due to accidental external force.

[0030] like Figure 1 As shown, the hanging shaft 2 has a T-shaped structure, and the overhead chain bracket 1 is provided with a hanging hole adapted to the T-shaped structure. During installation, the T-shaped head of the hanging shaft 2 is inserted through the upper circular hole of the hanging hole, and then moved downwards, causing the journal of the hanging shaft 2 to slide into the lower vertical groove of the hanging hole. The T-shaped head is then constrained by the mounting surface of the hanging hole, achieving connection. During disassembly, simply push the hanging shaft 2 upwards, causing the T-shaped head of the hanging shaft 2 to return from the vertical groove to the position of the hanging hole, and then the hanging shaft 2 can be removed. Through this T-shaped design, horizontally mounted fixtures can be easily mounted onto or removed from the overhead chain bracket 1.

[0031] like Figure 3 and Figure 4 As shown, the adjustable hanging beam mechanism 3 includes a crossbeam 31, a pin 32, and grooves 33. Multiple grooves 33 are spaced apart along the length of the crossbeam 31; preferably, the grooves 33 have an arc-shaped cross-section. The pin 32 passes through the upper part of the hook 4 and is positioned within the groove 33, thus suspending the hook 4 below the crossbeam 31. The radius of the pin 32 is smaller than the radius of the groove 33, allowing the pin 32 to slide between adjacent grooves 33 under external thrust, thereby adjusting the position of the pin 23 among multiple grooves 33. Simultaneously, the arc-shaped structure of the groove 33 effectively limits the pin 32, preventing it from sliding axially along the crossbeam 31 in the non-adjustable state, ensuring the stability of the mold shell during the hanging process.

[0032] Furthermore, the crossbeam 31 is equipped with a spirit level, which makes it easy for operators to observe the horizontal status of the hanging fixture.

[0033] In use, based on the width of the mold shell to be hoisted, the hook 4 is pre-placed in the groove 33 via the pin 32, and the limiting block 5 is installed on the outside for pre-limiting. The adjustable hanging beam mechanism 3 hangs the entire horizontal hanging fixture onto the suspension bracket 1 via the hanging shaft 2. The operator places both ends of the mold shell into the hooks of the hooks 4 on both sides and observes the horizontal state of the mold shell. If the mold shell is tilted, the mold shell or hook 4 can be pushed while the fixture is stationary, so that the pin 32 slides from one groove 33 to the adjacent groove 33. The positions of the two hooks 4 on the adjustable hanging beam mechanism 3 are adjusted until the hoisted mold shell is horizontal. The horizontal state is verified with the help of a spirit level.

[0034] Example 2

[0035] Another embodiment of this example, such as Figure 5 As shown, the improvement compared to Embodiment 1 lies in the different structures of the grooves 33 and the different spacing between the grooves 33.

[0036] The groove 33 is divided into a coarse adjustment groove 331 and a fine adjustment groove 332. The coarse adjustment groove 331 is located at both ends of the adjustable hanging beam mechanism 3, and the fine adjustment groove 332 is located in the middle of the groove 33. The groove spacing between adjacent coarse adjustment grooves 331 is greater than the groove spacing between adjacent fine adjustment grooves 332. The coarse adjustment groove 331 is used to quickly and extensively position the hook 4 according to the width of the mold shell, thereby improving the efficiency of preparation work. The fine adjustment groove 332 is used to finely adjust the horizontal state of the mold shell after it is mounted.

[0037] The bottom of the coarse adjustment groove 331 is provided with a positioning groove 333, the radius of which is larger than that of the pin 32. When the pin 32 falls into the positioning groove 333, it provides the operator with a clear sense of positioning and prevents the pin 32 from sliding freely during non-active adjustment, thus enhancing the stability and safety of the coarse adjustment operation. An inclined guide surface 334 is provided between adjacent grooves of the groove 33 to ensure smooth movement of the pin 32 and increase the contact area under force. Preferably, the cross-section of the inclined guide surface 334 is arc-shaped, reducing wear on the pin 32 during movement and reducing pressure when adjusting the pin 32. By dividing the groove into coarse adjustment grooves and fine adjustment grooves with different spacing and arranging them in sections, a highly efficient operation process of "quick positioning first, then fine adjustment" is achieved. This design balances adjustment efficiency and adjustment accuracy, and is particularly suitable for situations where lifting mold shells are frequently changed on the production line.

[0038] Furthermore, a wear-resistant coating is sprayed onto the surface of the groove 33 to reduce wear between the pin 32 and the groove 33 and increase the service life of the pin 32 and the groove 33.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
