Description

Technical Field

[0001] This utility model relates to the field of injection molding production technology, specifically to a quick connection device for cooling water channels in injection molds. Background Technology

[0002] The design of the cooling water channel for injection molds is a key factor in ensuring that the mold maintains an appropriate temperature during the injection process, improving production efficiency and product quality. A reasonable cooling system can effectively reduce the mold temperature, shorten the molding cycle, reduce thermal deformation, and improve the consistency of finished products.

[0003] For example, Chinese patent application CN210484929U discloses a water pipe connector, including a hexagonal body and two threaded connecting parts. The hexagonal body and the threaded connecting parts have interconnected channels. The outer edges of both ends of the hexagonal body extend axially to form extension sleeves. Retractable bellows are fixed to both ends of the hexagonal body. The outer diameter of the bellows is smaller than the inner diameter of the extension sleeves. The ends of the bellows at both ends of the hexagonal body are fixedly connected to one of the threaded connecting parts. The threaded connecting parts are engaged with the corresponding extension sleeves after the bellows retracts.

[0004] However, the water pipe connector relies on rotating the threaded connection part for both disassembly and assembly, making the operation complicated and inefficient when repairing or replacing the water pipe.

[0005] Based on this, this utility model designs a quick connection device for the cooling water circuit of injection molds to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a quick connection device for the cooling water circuit of injection mold.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0010] Furthermore, the docking installation component includes a threaded tube and a docking structure. The threaded tube is threadedly connected to the port of the cooling water channel, and the docking structure is connected to the threaded tube and the pressing and rotating component. The outer side of the threaded tube away from the cooling water channel is polygonally shaped for easy disassembly and assembly.

[0011] Furthermore, the mating mounting component also includes a sealing ring, which is disposed between the threaded pipe and the cooling water passage for sealing.

[0012] Furthermore, the docking structure includes a connecting pipe, a spring, a push plate, and two limiting posts. The connecting pipe is fixedly connected to the threaded pipe.

The two ends of the spring are fixedly connected to the connecting pipe and the push plate, respectively. The two limiting posts are symmetrically arranged and fixedly installed on the outside of the end of the connecting pipe away from the threaded pipe. The connecting pipe, the push plate, and the limiting posts are connected to the pressing and rotating component.

[0013] Furthermore, the pressing and rotating component includes a connecting tube, a sliding groove tube, and an O-ring. The connecting tube is located inside the connecting tube and is slidably inserted into it. An O-ring is fixedly installed on the outside of the connecting tube for sealing with the connecting tube. The sliding groove tube is fixedly installed on the outside of the connecting tube, and a gap is formed between the sliding groove tube and the connecting tube for use with the connecting tube. The sliding groove tube has two L-shaped grooves symmetrically opened on its upper and lower sides for use with limiting posts. The limiting posts are located in the L-shaped grooves of the sliding groove tube and are engaged with the sliding groove tube. The sliding groove tube abuts against the push plate, and the end of the sliding groove tube away from the push plate is connected to the leak-proof rotating connecting component.

[0014] Furthermore, the leak-proof rotary connection assembly includes a rotary connecting component and a leak-proof detection component. The rotary connecting component is connected to the sliding groove pipes installed on the outside of two corresponding cooling water channels, and the leak-proof detection component is installed on the outside of the rotary connecting component.

[0015] Furthermore, the rotary connection component includes two rotary joints and a docking hose. The rotary joints are L-shaped, with one end of the rotary joint being sealed and rotatably connected to the grooving pipe, and the other end of the rotary joint being inserted into the docking hose. The outer sides of the two rotary joints are connected to the leak detection component.

[0016] Furthermore, the leak detection component includes two elastic rings and a transparent soft sleeve. The two elastic rings are respectively fitted onto the outside of the two rotary joints and sealed and snapped into the rotary joints. The transparent soft sleeve is fitted onto the outside of the two rotary joints and fixedly connected to the two elastic rings. A detection substance is placed inside the transparent soft sleeve, and the detection substance changes color when it comes into contact with water.

[0017] Compared with the prior art, the advantages of this utility model are as follows: 1. By connecting the pressing and rotating parts with the docking installation parts through pressing and rotating methods, the connection is quick and avoids accidental contact that could cause the pressing and rotating parts and the docking installation parts to detach, thus improving stability.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5A quick connection device for cooling water channels of injection molds includes a connection component 2 and a leak-proof rotating connection component 3.

[0029] The connecting assembly 2 includes multiple docking mounting parts 21 for communicating with the injection mold and multiple pressing and rotating parts 22 for quick connection with the docking mounting parts 21. The pressing and rotating parts 22 are connected to the leak-proof rotating communication assembly 3.

[0030] When the quick-connect device for cooling water circuit of injection mold is in normal use, the docking mounting component 21 is installed on the injection mold, the pressing and rotating component 22 is aligned with the docking mounting component 21 and pressed and rotated to quickly complete the connection. Then, the leak-proof rotating connecting component 3 is installed between the two pressing and rotating components 22 that need to be connected to complete the connection of the cooling water circuit. The connection between the pressing and rotating component 22 and the docking mounting component 21 is quick and avoids accidental contact that could cause the pressing and rotating component 22 and the docking mounting component 21 to detach, thus improving stability. At the same time, the setting of the leak-proof rotating connecting component 3 can quickly detect water leakage and repair it in time.

[0031] The docking installation component 21 includes a threaded tube 211 and a docking structure. The threaded tube 211 is threadedly connected to the port of the cooling water channel. The docking structure is connected to the threaded tube 211 and the pressing and rotating component 22. The outer side of the threaded tube 211 away from the cooling water channel is polygonal for easy disassembly and assembly.

[0032] The docking mounting component 21 also includes a sealing ring 212, which is disposed between the threaded pipe 211 and the cooling water passage for sealing.

[0033] The docking structure includes a connecting pipe 213, a spring 214, a push plate 215, and two limiting posts 216. The connecting pipe 213 is connected and fixedly connected to the threaded pipe 211. The spring 214 and the push plate 215 are sleeved on the outside of the connecting pipe 213. The push plate 215 is slidably connected to the connecting pipe 213. The two ends of the spring 214 are fixedly connected to the connecting pipe 213 and the push plate 215 respectively. The two limiting posts 216 are symmetrically arranged and fixedly installed on the outside of the end of the connecting pipe 213 away from the threaded pipe 211. The connecting pipe 213, the push plate 215, and the limiting posts 216 are connected to the pressing and rotating component 22.

[0034] The pressing and rotating component 22 includes a connecting pipe 221, a sliding groove pipe 222, and an O-ring 223. The connecting pipe 221 is located inside the connecting pipe 213 and is slidably inserted into the connecting pipe 213. An O-ring 223 is fixedly installed on the outside of the connecting pipe 221 for sealing with the connecting pipe 213. The sliding groove pipe 222 is fixedly installed on the outside of the connecting pipe 221. A gap is formed between the sliding groove pipe 222 and the connecting pipe 221 to cooperate with the connecting pipe 213. The sliding groove pipe 222 has two L-shaped grooves symmetrically opened on its upper and lower sides for cooperating with the limiting post 216. The L-shaped groove is divided into two sections along the axial and circumferential directions of the sliding groove pipe 222. The limiting post 216 is located in the L-shaped groove of the sliding groove pipe 222 and is engaged with the sliding groove pipe 222. The sliding groove pipe 222 abuts against the push plate 215. The end of the sliding groove pipe 222 away from the push plate 215 is connected to the leak-proof rotating connecting component 3.

[0035] The leak-proof rotary connection assembly 3 includes a rotary connection component 31 and a leak-proof detection component 32. The rotary connection component 31 is connected to the sliding groove pipes 222 installed on the outside of two corresponding cooling water channels, and the leak-proof detection component 32 is installed on the outside of the rotary connection component 31.

[0036] The rotary connection component 31 includes two rotary joints 311 and a docking hose 312. The rotary joints 311 are L-shaped. One end of the rotary joint 311 is sealed and rotatably connected to the slide tube 222, and the other end of the rotary joint 311 is inserted into the docking hose 312. The outer sides of the two rotary joints 311 are connected to the leak detection component 32.

[0037] The rotary connection component 31 also includes two sealing rings 313, which are fixedly installed on the inner side of the rotary joint 311. The sealing rings 313 are used to seal between the rotary joint 311 and the docking hose 312.

[0038] The leak detection component 32 includes two elastic rings 321 and a transparent soft sleeve 322. The two elastic rings 321 are respectively fitted on the outside of the two rotary joints 311 and sealed and snapped into the rotary joints 311. The transparent soft sleeve 322 is fitted on the outside of the two rotary joints 311 and fixedly connected to the two elastic rings 321. The detection substance is placed inside the transparent soft sleeve 322. The detection substance changes color when it comes into contact with water. The detection substance is anhydrous copper sulfate powder.

[0039] When the quick-connect device for the injection mold cooling water circuit is in normal use, the threaded pipe 211 is threadedly connected to the cooling water circuit port, and the sealing ring 212 is used for sealing. The connecting pipe 221 and the sliding pipe 222 are pushed toward the connecting pipe 213. The connecting pipe 221 drives the push plate 215 to compress the spring 214. The limiting post 216 enters along the L-shaped groove of the sliding pipe 222 near the end of the push plate 215 and moves along the axial section of the L-shaped groove to the junction of the two sections of the L-shaped groove. The connecting pipe 221 is sealed and inserted into the inner side of the connecting pipe 213. Rotating the connecting pipe 221 and the sliding pipe 222 causes the limiting post 216 to continue moving along the circumferential section of the L-shaped groove of the sliding pipe 222 to the other end of the L-shaped groove. The limiting post 216 is locked with the sliding pipe 222. Rotating the rotary joint 311 causes the two corresponding rotary joints to... With heads 311 facing each other, a tension ring 321 and a transparent soft sleeve 322 are fitted onto the outside of a rotary joint 311. The connecting hose 312 is cut to a suitable length and inserted into the two rotary joints 311 respectively. A sealing ring 313 is used for sealing. One tension ring 321 is pulled to the outside of the other rotary joint 311 so that the transparent soft sleeve 322 completely wraps around the connecting hose 312. When water leaks at the rotary joint 311 and the connecting hose 312, water enters the inside of the transparent soft sleeve 322 and reacts with the detection substance. The color change of the detection substance can be observed from the outside, allowing for repair. By rotating the rotary joint 311 and cutting the connecting hose 312 to any length, two cooling water channels at any position can be connected.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
