Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a quick assembly and disassembly structure for mold parts. Background Technology

[0002] In the mold manufacturing and maintenance process, the disassembly, assembly, and replacement of mold parts have a significant impact on production efficiency. Traditional mold parts use an internal fixing screw structure (requiring the screw threads to be machined on the part before heat treatment), such as... Figure 1 As shown, the following disadvantages exist: (1) The process is complicated and the cost is high; (2) When processing hard materials, the EDM of the tooth hole will increase the cost and extend the cycle; (3) The long processing cycle of spare parts will easily lead to production delays.

[0003] Therefore, there is an urgent need for a simplified structure for disassembling and assembling mold parts to improve the efficiency of mold manufacturing and maintenance. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a quick assembly and disassembly structure for mold parts.

[0005] This utility model proposes a quick assembly / disassembly structure for mold parts, including a mold template and a part body. The part body is mounted on the template by quick-release screws. A standardized embedding groove is formed on one outer surface of the part body, and the nut side of the quick-release screw is embedded in the embedding groove. The mold template has a cavity that matches the part body and a threaded hole that matches the screw of the quick-release screw. Tightening the quick-release screw can quickly fix and separate the part body from the mold template.

[0006] Preferably, the quick-release screw is a stepped screw.

[0007] Preferably, the embedding groove is formed in one step by wire cutting.

[0008] Preferably, a dustproof sealing sleeve is provided on the outer side of the screw end near the nut of the quick-release screw, one end of the dustproof sealing sleeve is adapted to seal the opening of the embedded groove, and the other end is in contact with the surface of the mold template.

[0009] In summary, this utility model has the following beneficial effects: the part body does not require machining of threaded holes, reducing the processes of thread machining, heat treatment, and electrical discharge machining of hard material threads, thus lowering the part machining cost; the tapping process of the mold template is simple, which also saves machining costs, significantly reducing the overall machining cost of mold manufacturing; the part body and mold template can be quickly disassembled and assembled by tightening quick-release screws, which is simple and quick to operate, requiring no complicated tools and processes, effectively shortening the mold assembly and disassembly time and improving the efficiency of mold maintenance and debugging; the spare parts processing of the part body only requires machining of the embedded groove, which is simple and can be produced quickly. When mold parts are damaged, spare parts can be replaced in time, reducing production downtime and improving the production continuity and equipment utilization rate of the mold.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] like Figure 2-5As shown, this embodiment proposes a quick-release and assembly structure for mold parts, including a mold template 2 and a part body 1. The part body 1 is mounted on the template by quick-release screws 3. A standardized insert groove 11 is formed on one outer surface of the part body 1. The nut 31 of the quick-release screw 3 is inserted into the insert groove 11. The mold template 2 has a cavity that matches the part body 1 and a threaded hole that matches the screw 32 of the quick-release screw 3. Tightening the quick-release screw 3 can quickly fix and separate the part body 1 from the mold template 2. Specifically, the quick-release screw 3 is a stepped screw.

[0020] First, insert one side of the nut 31 of the quick-release screw 3 into the insertion groove 11 of the part body 1. Then, place the part body 1 with the quick-release screw 3 assembled in the designated position (corresponding to the cavity position) of the mold template 2. Finally, tighten the quick-release screw 3 so that the screw 32 of the quick-release screw 3 engages with the threaded hole on the mold template 2 to tighten it, thus completing the fixation of the part body 1. When disassembling, tighten the quick-release screw 3 in the opposite direction to quickly remove the part body 1 from the mold template 2.

[0021] Thus, the part body 1 does not require machining of threaded holes, reducing the need for thread machining, heat treatment, and electrical discharge machining of hard material threads, thereby lowering the part machining cost. The tapping process of the mold template 2 is simple and can also save machining costs, significantly reducing the overall machining cost of mold manufacturing. The part body 1 and the mold template 2 can be quickly disassembled and assembled by tightening the quick-release screws 3, which is simple and quick to operate, without the need for complicated tools and processes, effectively shortening the mold assembly and disassembly time and improving the efficiency of mold maintenance and debugging. The spare parts processing of the part body 1 only requires machining of the embedded groove 11, which is simple and can be produced quickly. When mold parts are damaged, spare parts can be replaced in time, reducing production downtime and improving the production continuity of the mold and the utilization rate of equipment.

[0022] The embedded groove 11 is formed in one step by wire cutting, which is a simple processing technology.

[0023] In a preferred embodiment, a dustproof sealing sleeve (not shown in the figure) is fitted around the outer side of the screw 32 end of the quick-release screw 3 near the nut 31. One end of the dustproof sealing sleeve is fitted to seal the opening of the insert groove 11, and the other end is in contact with the surface of the mold template 2. A sealed space is formed around the screw 32 of the quick-release screw 3, preventing the intrusion of external foreign objects (dust, debris). This protects the cleanliness of the threaded holes of the insert groove 11 and the mold template 2, ensuring smooth tightening of the quick-release screw 3 over a long period of time, reducing the risk of screw jamming and thread damage caused by foreign objects, and reducing maintenance costs and downtime. The reliable threaded connection overcomes the limitations of traditional mold parts assembly and disassembly structures that lack targeted protection. Optimizing the structure from a protection perspective for the dusty environment of mold production, it ensures the long-term reliability of screw tightening and threaded connection, extending the service life of the structure.

[0024] It should be noted that this solution differs from the traditional method of machining threaded holes on the part body 1. Instead, an embedding groove 11 is opened on the outer surface of the part body 1, structurally changing the connection method between the part body 1 and the screw. Through mechanical fitting combined with the threaded connection of the quick-release screw 3, the part body 1 is fixed on the mold template 2, simplifying the part processing technology and improving the efficiency of mold manufacturing and maintenance. The nut 31 of the quick-release screw 3 is adapted to the embedding groove 11 of the part body 1, and the screw 32 of the quick-release screw 3 is adapted to the threaded hole on the mold template 2. This split connection design utilizes the universality and ease of operation of the screw to achieve quick assembly and disassembly of the part, breaking through the limitations of the traditional thinking of fixing the screw inside the part. The mold template 2 only needs to be machined with simple threaded holes. Compared with the complex processing requirements for the connection between the template and the part in traditional molds, the processing difficulty and cost of the template are greatly reduced, and it is not affected by the material of the mold parts, thus improving the flexibility and efficiency of template processing.
