Description

Technical Field

[0001] This utility model relates to the field of mold assembly technology, specifically a mold for assembling and processing metal parts. Background Technology

[0002] Currently, in the assembly and connection process of metal parts processing molds, traditional mechanical fixing methods such as bolts, pins, or external pressure plates are commonly used to achieve docking and locking between the mold bodies. Although such connection structures can ensure a certain degree of stability, they have significant shortcomings under long-term use or high-frequency disassembly and assembly conditions.

[0003] In existing technologies, the mold body is usually directly connected to bolts via threaded holes. Assembly requires manual alignment and individual tightening, making the process cumbersome. Furthermore, due to the limited number of threaded locking positions, uneven mold engagement can easily occur due to eccentricity or assembly errors, affecting machining accuracy. In addition, in multi-mold assembly structures, molds need to be frequently replaced or repaired. Traditional bolt fixing methods are not only time-consuming but also prone to thread wear or stripping, reducing connection reliability.

[0004] To improve the assembly efficiency of molds, some improved structures add positioning pins or clamping blocks to the side walls of the molds to achieve semi-automatic connection. However, they still rely on manual alignment and positioning, and the connection strength is limited. Under high temperature, high pressure or vibration conditions, loosening is likely to occur, leading to misalignment or leakage between molds, which makes it difficult to meet the requirements of precision machining.

[0005] Especially in the processing of metal mold assembly, the repeated loading and unloading of multi-mold components is frequent. Traditional connection methods lack quick disassembly and anti-loosening structures, resulting in low mold maintenance efficiency and unstable installation accuracy, which seriously affects production cycle and mold life.

[0006] Therefore, there is an urgent need for a compact, easy-to-assemble and disassemble, and reliable metal parts assembly and processing mold that can achieve rapid mold closing and precise positioning while maintaining high-strength locking, overcoming the shortcomings of traditional connection structures in terms of installation efficiency, anti-loosening stability and service life. Utility Model Content

[0007] This invention aims to overcome the problems of cumbersome installation, low locking efficiency, insufficient connection accuracy, and easy loosening in existing mold assembly structures, and provides a metal parts assembly mold. This structure achieves rapid assembly and high-strength locking of the mold by setting detachable connecting parts between the mold bodies. While maintaining high-precision alignment, it also has good anti-loosening performance, significantly improving the assembly efficiency and stability of the mold.

[0008] This utility model provides a metal parts assembly processing mold, including a mold body, a locking screw and several assembly connecting parts.

[0009] The mold body is the processing base, and its two end faces are respectively provided with mounting grooves for installing the combined connecting parts; the combined connecting parts are installed between adjacent mold bodies to realize detachable mechanical connection; the locking screw passes through the internal threaded pin hole of the connecting part and realizes axial locking through thread engagement.

[0010] The entire mold connection structure is composed of three parts: "plug-in positioning + threaded locking + elastic limiting". This allows for repeated assembly and disassembly, high-strength locking and anti-loosening limiting functions between the main body of the mold. The structure is compact and the assembly is reliable.

[0011] In a preferred embodiment, mounting grooves are provided on both ends of the mold body for the embedded installation of the connecting components. This design allows the connecting components to be embedded within the end faces of the mold body, enabling modular assembly.

[0012] Specifically, by using a pre-set mounting slot, the mold can be automatically guided and positioned during assembly, ensuring assembly accuracy and improving the consistency of mold closing.

[0013] In a preferred embodiment, the combined connector includes a connecting box and a plug. The connecting box is fixed inside the mold body, and its inner side has a slot for the plug to be inserted and engaged. A semi-circular threaded pin hole is also provided on the inner side of the connecting box for threaded engagement with a locking screw.

[0014] Specifically, the precise docking between molds is achieved through the mutual insertion and cooperation of the connecting box and the plug, ensuring the positional stability and tightness of the mold during repeated opening and closing.

[0015] In a preferred example, in two opposing mold bodies, the plug portion of the first mold body is inserted into a slot within the connector box of the second mold body. The plug portion has an arc-shaped groove on its outer side; when the two mold bodies are joined, the arc-shaped groove combines to form a ring structure for locking the through screw.

[0016] Specifically, the circular structure formed by the arc grooves on both sides of the plug can achieve radial enveloping locking, keeping the locking screw stable and centered during the stress process, thus improving shear and seismic resistance.

[0017] In a preferred embodiment, the locking screw passes through the threaded pin hole and engages with its threaded section to achieve axial locking of the plug portion. The locking screw has an internal hexagonal structure and a limiting flange at its end for controlling the thread locking depth.

[0018] Specifically, the structure forms a high-strength axial lock through a threaded connection, while the limiting flange prevents the threads from being over-screwed and causing damage, ensuring a tight connection of the mold body and maintaining long-term anti-loosening.

[0019] In a preferred embodiment, the plug portion employs a triangular insertion structure, with its outer end width being smaller than its inner end width, forming a progressive guide slope. During insertion, the plug portion is gradually pressed into the slot, achieving automatic positioning and alignment.

[0020] Specifically, this structure facilitates automatic angle correction between the plug and the connector box during assembly, avoiding manual alignment errors and improving assembly accuracy.

[0021] In a preferred example, the arc groove is an elastic strip structure, and the plug and the slot have the same width.

[0022] Specifically, the elastic arc groove strip undergoes elastic deformation when the locking screw is tightened, providing shock absorption and buffering functions for the connection structure and preventing the mold from loosening due to vibration or thermal expansion.

[0023] In a preferred example, the connecting box adopts a one-piece metal structure and is fixed to the inner wall of the mold body by welding or threaded connection.

[0024] Specifically, the one-piece molding structure enhances the rigidity and wear resistance of the connecting box, maintaining structural stability under high temperature or high pressure conditions and effectively extending the service life of the mold.

[0025] In a preferred example, the locking screw, connecting box, and plug are all made of low-carbon steel.

[0026] Specifically, low-carbon steel possesses excellent plasticity and toughness, ensuring that the connecting parts do not deform or fatigue under long-term repeated locking and vibration conditions, thus ensuring the assembly strength and reliability of the mold.

[0027] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by setting combined connecting parts at both ends of the mold body, the plug is inserted into the slot in the connecting box and locked by the locking screw, so as to realize the rapid assembly and reliable positioning between the mold bodies, which greatly reduces the alignment difficulty and installation time of traditional bolt connection.

[0028] 2. In this utility model, the arc groove strips on the plug part are combined to form a ring structure, and are locked with the locking screw to form a two-way limiting support. While maintaining the connection strength, it has an elastic anti-loosening function, which can effectively prevent the mold from displaced and loosened during high-frequency opening and closing or vibration processing.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0032] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0033] The following describes, with reference to the accompanying drawings, some embodiments of a metal parts assembly processing mold provided by this utility model.

[0034] Combination Figures 1-5 As shown, the present invention provides a metal parts assembly processing mold, including a mold body 100, a locking screw 200 and several assembly connecting parts 300.

[0035] The mold body 100 has mounting grooves on both ends for mounting the combined connector 300. These mounting grooves allow the combined connector 300 to be embedded inside the mold body 100, achieving precise positioning and stable connection between the mold bodies 100.

[0036] The combined connector 300 is used for a detachable connection between adjacent mold bodies 100, and includes a connector box 310 and a plug portion 320. The connector box 310 has a slot 311 located on one side of the plug portion 320 for insertion and engagement. The connector box 310 also has a semi-circular threaded pin hole 312 inside, which engages with a locking screw 200 to form an axial lock.

[0037] In this embodiment, the plug portion 320 is inserted into the slot 311 of another connecting box 310. An arc groove 321 is provided on one side of the plug portion 320. When the two mold bodies 100 are assembled relative to each other, the two plug portions 320 abut against each other, and the arc groove 321 combine to form a ring structure. The locking screw 200 passes through this ring structure and connects to the threaded pin hole 312, thereby achieving reliable locking and anti-loosening positioning of the plug portion 320.

[0038] In this structure, the locking screw 200 passes through the threaded pin hole 312 and is threadedly engaged with it. By tightening the locking screw 200, the ring formed between the two plug parts 320 can be locked in the axial direction, preventing the two mold bodies 100 from separating, thereby achieving high-strength locking.

[0039] In a preferred embodiment, the plug portion 320 adopts a triangular insertion structure, with its outer end width being smaller than its inner end width, forming a guide cone surface structure. This structure facilitates automatic centering and guidance of the plug portion 320 during insertion, improving assembly accuracy. When the arc groove strip 321 on one side cooperates with the other plug portion 320, it can form a symmetrical limiting arc structure, enabling the locking screw 200 to be centrally positioned within the ring, further enhancing locking stability.

[0040] In another preferred embodiment, the arc groove 321 is an elastic strip structure. When the locking screw 200 is inserted, the arc groove 321 undergoes a slight elastic deformation under force, thereby covering and limiting the locking screw 200, providing anti-loosening and buffering performance. The plug portion 320 and the slot 311 have the same width, ensuring uniform assembly clearance and preventing connection misalignment.

[0041] Furthermore, the threaded pin hole 312 and the locking screw 200 are coaxially arranged, and the locking screw 200 adopts an internal hexagonal structure, which facilitates assembly and disassembly operations using standard tools. The end of the locking screw 200 is provided with a limiting flange to control the locking depth and prevent the thread from being screwed in too deeply and damaging the plug part 320 or the connecting box 310.

[0042] In a preferred embodiment, the connecting box 310 adopts a one-piece metal structure and is fixedly installed on the inner wall of the mold body 100 by welding or threaded connection, so that the connecting box 310 and the mold body 100 form a high-strength integral connection structure, thereby improving the overall rigidity and deformation resistance of the mold.

[0043] Furthermore, the locking screw 200, connecting box 310, and plug part 320 are all made of low-carbon steel. This material has good toughness and elasticity, and can maintain a stable connection under long-term high temperature, high pressure, and high frequency opening and closing conditions, avoiding structural fatigue or fracture and ensuring the reliability of the mold for long-term use.

[0044] In the working state of this utility model, when two mold bodies 100 need to be connected, the operator first inserts the plug part 320 into the slot 311 of the connecting box 310 on the adjacent mold body 100. Then, align the arc groove strip 321 to ensure that the two plug parts 320 are correctly aligned and form a ring. Finally, screw in the locking screw 200 to lock it into the threaded pin hole 312. Through the constraint of the limiting flange, the locking screw 200 can reliably lock and prevent loosening, achieving a high-strength connection between the mold bodies 100.

[0045] When mold disassembly is required, simply unscrew the locking screw 200 in reverse, and the two plug parts 320 can be separated, enabling quick assembly and modular replacement of the mold. This structure effectively improves the assembly efficiency and maintenance convenience of the mold.

[0046] In summary, the metal parts assembly processing mold of this utility model achieves modular rapid assembly by setting assembly connectors 300 at both ends of the mold body 100. It has high connection strength, good anti-loosening performance and repeated assembly stability. The overall structure is simple and reliable, and it is suitable for various metal mold assembly processing scenarios.
