Description

Technical Field

[0001] This application relates to the field of injection molding machine technology, and more specifically, to an injection molding machine nozzle that is easy to disassemble. 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.

[0003] For example, CN220219452U discloses a semi-automatic injection molding machine with easy nozzle replacement. Addressing the problem that existing semi-automatic injection molding machines with easy nozzle replacement suffer from inconvenience in nozzle disassembly and installation, leading to lengthy replacement times, the following solution is proposed: It includes a fixed frame, with a feed pipe fixedly connected to the top of the fixed frame, and an injection nozzle slidingly mounted on the bottom of the feed pipe. A sealing gasket is fixedly connected to the injection nozzle, with the top of the sealing gasket abutting against the bottom of the feed pipe. Sliding components are provided on both sides of the injection nozzle, and fixing grooves are formed on the inner walls of both sides of the fixed frame. A push plate is slidably connected within the fixing groove, and a push rod is fixedly connected to the push plate. The push rod is slidably connected to the fixed frame, and fixing components are provided on the fixed frame. This device can fix the injection nozzle in place and facilitate its disassembly and replacement.

[0004] The aforementioned patent requires workers to rotate two handles to disassemble the injection molding machine nozzle, which increases the complexity of disassembling the nozzle and reduces its efficiency.

[0005] To address the aforementioned problems, this application provides an injection molding machine nozzle that is easy to disassemble. Utility Model Content

[0006] The injection molding machine nozzle that is easy to disassemble provided in this application adopts the following technical solution:

[0007] A disassembleable injection molding machine nozzle includes a nozzle body, one end of which is engaged with a connector ring. The upper end of the connector ring is provided with a locking assembly. A limiting assembly is formed inside the connector ring. A locking block is fixedly connected to the lower outer surface of the nozzle body. The limiting assembly includes a sliding groove, an annular groove, and a locking groove formed on the inner wall of the connector ring. The upper end of the connector ring has a first circular groove. The top wall of the annular groove has a placement groove. The center of the top wall of the placement groove has a second circular groove. The locking assembly includes a sliding rod slidably connected inside the first circular groove. The upper end of the sliding rod is fixedly connected to a top plate. The lower end of the sliding rod is fixedly connected to a connecting rod. The lower end of the connecting rod is fixedly connected to a pressure block. A spring is fixedly connected to the center of the upper end of the pressure block.

[0008] Furthermore, the sliding groove is located on the inner wall of the upper end of the connector ring, the slot is located below the placement groove, the slot is connected to the placement groove, and the second circular groove is connected to the first circular groove.

[0009] With the above technical solution, under the action of the placement groove and the second circular groove, it can directly extend into the card slot through the first circular groove on the outside. The placement groove is used to place unused pressure blocks.

[0010] Furthermore, the locking block is slidably connected to the sliding groove, the locking block is rotatably connected to the annular groove, and the locking block is slidably engaged with the locking groove.

[0011] Through the above technical solution, the existence of the groove facilitates the insertion of the locking block into the inside of the connector ring, that is, the lower end of the nozzle body extends into the inside of the connector ring. The ring groove facilitates the rotation of the locking block along it, that is, the nozzle body rotates inside the connector ring. The locking groove is used to limit and engage the locking block.

[0012] Furthermore, the slide rod passes through the interior of the first circular groove, the top plate is located above the joint ring, the slide rod is slidably connected to the second circular groove, the pressure block is slidably engaged with the placement groove, the spring is located around the connecting rod, and the upper end of the spring is fixedly connected to the top wall of the second circular groove.

[0013] The above technical solution facilitates the movement of the pressure block towards the placement groove by pulling the top plate from the outside. The presence of the first and second circular grooves is used to support the upper end of the spring, and the spring pushes the pressure block away from the placement groove.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] This application allows for easy removal of the nozzle body from the inner wall of the connector ring. The top plate can drive the pressure block to move closer to the placement groove. The spring's rebound pushes the pressure block to separate from the placement groove and presses against the locking block, so that the locking block cannot separate from the locking groove without the top plate being subjected to external force, thus preventing the nozzle body from accidentally falling out of the connector ring.

[0027] Example:

[0028] This application discloses an easily detachable injection molding machine nozzle. Please refer to [link / reference]. Figures 1-6The nozzle body 1 is included. One end of the nozzle body 1 is engaged with a connector ring 2. The upper end of the connector ring 2 is provided with a locking component 3. A limiting component 4 is provided inside the connector ring 2. A locking block 11 is fixedly connected to the lower outer surface of the nozzle body 1. The limiting component 4 includes a sliding groove 41, an annular groove 42 and a locking groove 43 provided on the inner wall of the connector ring 2. The upper end of the connector ring 2 is provided with a first circular groove 21. The top wall of the annular groove 42 is provided with a placement groove 23. The center of the top wall of the placement groove 23 is provided with a second circular groove 22. The locking component 3 includes a sliding rod 32 slidably connected inside the first circular groove 21. The upper end of the sliding rod 32 is fixedly connected with a top plate 31. The lower end of the sliding rod 32 is fixedly connected with a connecting rod 33. The lower end of the connecting rod 33 is fixedly connected with a pressure block 35. The center of the upper end of the pressure block 35 is fixedly connected with a spring 34.

[0029] The sliding groove 41 is located on the inner wall of the upper end of the connector ring 2, the slot 43 is located below the placement groove 23, the slot 43 is connected to the placement groove 23, and the second circular groove 22 is connected to the first circular groove 21.

[0030] Under the action of the placement groove 23 and the second circular groove 22, it can directly extend into the card slot 43 through the first circular groove 21 outside. The placement groove 23 is used to place unused pressure blocks 35.

[0031] The locking block 11 is slidably connected to the sliding groove 41, the locking block 11 is rotatably connected to the annular groove 42, and the locking block 11 is slidably engaged with the locking groove 43.

[0032] The presence of the groove 41 facilitates the insertion of the locking block 11 into the interior of the connector ring 2, so that the lower end of the nozzle body 1 extends into the interior of the connector ring 2. The ring groove 42 facilitates the rotation of the locking block 11 along it, that is, the nozzle body 1 rotates inside the connector ring 2. The locking groove 43 is used to limit and engage the locking block 11.

[0033] The slide rod 32 passes through the interior of the first circular groove 21, the top plate 31 is located above the joint ring 2, the slide rod 32 is slidably connected to the second circular groove 22, the pressure block 35 is slidably engaged with the placement groove 23, the spring 34 is located around the connecting rod 33, and the upper end of the spring 34 is fixedly connected to the top wall of the second circular groove 22.

[0034] By pulling the top plate 31, the pressure block 35 is moved closer to the placement groove 23. The presence of the first circular groove 21 and the second circular groove 22 is used to support the upper end of the spring 34. The spring 34 pushes the pressure block 35 away from the placement groove 23.

[0035] The implementation principle of this embodiment is as follows: When the nozzle body 1 needs to be disassembled for maintenance, the operator first pulls the top plate 31 to drive the slide rod 32 to slide along the first circular groove 21. Under the action of the connecting rod 33, the top plate 31 can pull the pressure block 35 closer to the placement groove 23. At this time, the spring 34 is compressed until the pressure block 35 and the placement groove 23 form a locking connection. Then, the nozzle body 1 can be pulled to separate the locking block 11 from the locking groove 43 to the lower end of the pressure block 35, that is, the locking block 11 is moved to the annular groove 42. Then, the nozzle body 1 is rotated to drive the locking block 11 to rotate along the annular groove 42 to the sliding groove 41. Then, the nozzle body 1 can be pulled again to separate the locking block 11 from the sliding groove 41, and the nozzle body 1 can be removed from the inside of the connector ring 2.

[0036] When it is necessary to reinstall the nozzle body 1, the reverse operation is performed. When the locking block 11 re-enters the locking groove 43, the top plate 31 can be released. At this time, the squeezing force on the spring 34 disappears. Under the action of the spring 34's rebound, the pressure block 35 will be pushed to separate from the placement groove 23, and the pressure block 35 will continue to move downward until the pressure block 35 touches the lower end of the locking block 11. At this time, under the pushing force of the spring 34, the pressure block 35 is prevented from separating from the locking block 11, so that the locking block 11 cannot separate from the locking groove 43 without the action of external force on the top plate 31, that is, to prevent the nozzle body 1 from accidentally falling out of the inside of the connector ring 2.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
