Description

Technical Field

[0001] This utility model relates to the field of injection molding machine cooling technology, specifically a modular injection molding machine cooling system batch quick-release device. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. Because injection molding machines can heat the plastic and apply high pressure to the molten plastic, causing it to be injected and fill the mold cavity, injection molding machines need to be cooled during use to achieve a cooling effect.

[0003] RO reverse osmosis membranes are the core component for achieving reverse osmosis. They are artificial semi-permeable membranes with specific characteristics, mimicking biological semi-permeable membranes. They are generally made of polymer materials. Because RO reverse osmosis technology is widely used in industrial wastewater treatment and domestic drinking water production, the end caps, central tubes, and connectors of RO reverse osmosis membrane elements are all injection-molded products, and each product has multiple different specifications. During production, molds frequently need to be changed, and the cooling pipes on the molds require cooling water, necessitating cooling pipelines. In practical applications, due to the numerous cooling pipelines, frequent disassembly not only increases labor costs and affects production cycles but also leads to damage to joints or water pipes. This damage can cause leaks, resulting in poor cooling performance and requiring machine downtime for maintenance. This affects both processing efficiency and product quality. To meet the cooling requirements of injection molding machines, facilitate disassembly, reduce processing costs, and improve work efficiency, it is essential to provide a quick-disassembly device suitable for mass production.

The lower connecting pipe joint 22 communicates with the mating hole 23. The upper connector 11 is inserted into the plug hole 23 in the lower connector 21 via the plug connector 13, thereby realizing the detachable connection between the upper connector 11 and the lower connector 21. A detachable fixing unit 3 is provided between the upper connecting unit 1 and the lower connecting unit 2, and the fixing unit 3 is used to connect the upper connecting unit 1 and the lower connecting unit 2.

[0025] Furthermore, in the modular injection molding machine cooling system batch quick-disassembly device described in this utility model, there are two upper connecting pipe joints 12 and two lower connecting pipe joints 22. The two upper connecting pipe joints 12 and the two lower connecting pipe joints 22 are arranged symmetrically on the front and rear sides of the corresponding upper connecting seat 11 and lower connecting seat 21. The mating connector 13 and mating hole 23 are provided in twos. The bottom surface of the upper connecting seat 11 is provided with two connector mounting holes 14 arranged symmetrically. The two connector mounting holes 14 are respectively connected to the two upper connecting pipe connectors 12 arranged in front and behind. The mating connector 13 is set on the bottom surface of the upper connecting seat 11 through the connector mounting hole 14. One mating connector 13 is connected to the upper connecting pipe connector 12 located on the front side of the upper connecting seat 11 through the connector mounting hole 14, and the other mating connector 13 is connected to the upper connecting pipe connector 12 located on the rear side of the upper connecting seat 11 through another connector mounting hole 14. The two mating holes 23 are arranged symmetrically on the surface of the lower connecting seat 21 and correspond to the mating connector 13. One mating hole 23 communicates with the lower connecting pipe connector 22 located on the front side of the lower connecting seat 21, and the other mating hole 23 communicates with the lower connecting pipe connector 22 located on the rear side of the lower connecting seat 21. The upper connecting seat 11 is inserted into the two corresponding plug holes 23 in the lower connecting seat 21 through the two plug-in connectors 13, and is connected by the fixing unit 3, so that the upper connecting pipe connector 12 and the lower connecting pipe connector 22 located on the front side of the upper connecting seat 11 and the lower connecting seat 21, and the upper connecting pipe connector 12 and the lower connecting pipe connector 22 located on the rear side of the upper connecting seat 11 and the lower connecting seat 21 are respectively connected.

[0026] Furthermore, in the modular injection molding machine cooling system batch quick-release device provided in this embodiment, the fixing unit 3 includes an adjusting screw sleeve 31, a limiting nut 32, and a locking pin 33; the upper connecting seat 11 is provided with a screw sleeve mounting hole 34 corresponding to the adjusting screw sleeve 31, and the lower connecting seat 21 is provided with a quick-release hole 35 corresponding to the locking pin 33. The adjusting screw sleeve 31 is connected to the upper connecting seat 11 through the screw sleeve mounting hole 34, and the surface of the locking pin 33 is provided with an adjusting thread 331 corresponding to the adjusting screw sleeve 31 and the limiting nut 32.

In actual manufacturing, the internal threads of the adjusting sleeve 31 and the limiting nut 32 must match the adjusting thread 331 on the surface of the locking pin 33. This facilitates screwing the locking pin 33 into the adjusting sleeve 31 and also allows for easy fixing of the locking pin 33 using the limiting nut 32. In practice, two limiting nuts 32 can be used, overlapping and screwed into the locking pin 33 from top to bottom to enhance stability.

[0027] Furthermore, in the modular injection molding machine cooling system batch quick-release device provided in this embodiment, the fixing unit 3 further includes a stop lock 36.

The upper connecting hole 351 is provided with an oblong hole structure, while the lower connecting hole 352 is provided with a round hole structure, and its inner diameter is larger than the inner diameter of the upper connecting hole 351.

[0028] By using the stop lock 36 located at the lower end of the locking pin 33, and since the quick-release hole 35 forms a stepped hole structure with a ring-shaped surface through the upper connecting hole 351 and the lower connecting hole 352, it is only necessary to insert the locking pin 33 into the quick-release hole 35 from bottom to top, and its upper end is screwed into the adjusting screw sleeve 31 and extends upward to the top of the adjusting screw sleeve 31. Finally, the limiting nut 32 is used for screwing and fixing, thus fixing the upper connecting seat 11 and the lower connecting seat 21. Example 2

This not only facilitates disassembly and assembly, but also meets the cooling requirements of the injection molding machine.

[0040] In summary, the quick-release device described in this utility model, with its modular assembly method, allows for the rational selection of the number of inlet and outlet pipes according to the needs of the mold cooling system. This not only meets the connection requirements of multiple water pipes but also prevents water leakage caused by damage to joints or water pipes during frequent disassembly, thus preventing product quality issues due to poor cooling.
