[0003] However, the current injection molding heads are mostly irregular in shape and the internal pipe design is complex, which makes cleaning difficult. In particular, the pipes inside the injection molding head are often tightly integrated with other components and difficult to remove separately. This results in a lot of time and manpower required to clean the injection molding head, affecting the service life and production efficiency of the injection molding machine. Summary of the invention

[0004] In order to solve the above technical problems, it is necessary to develop a new type of injection head structure that is easy to clean and replace. This new injection head should have a simple structural design, so that the staff can easily disassemble it and clean or replace the internal pipes separately, thereby reducing the difficulty and time cost of cleaning work and improving the operation efficiency and production efficiency of the injection molding machine.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an injection head of an injection molding machine that is easily disassembled and assembled, comprising an injection head body, a heating component, a screw component, a sealing component and a main body component; an elastic ring is fixedly connected to the inner wall of one end of the injection head body, and a diaphragm baffle is fixedly arranged at the other end, and a mounting slot is opened in the middle of the diaphragm baffle; the heating component is arranged on the inner wall of the injection head body, the screw component is arranged on the inner side of one end of the injection head body, located between the heating component and the diaphragm baffle, the sealing component is arranged on the outer side of the diaphragm baffle of the injection head body, and the main body component is arranged on the inner wall of the heating component, one end of which passes through the inner wall of the elastic ring, and the other end is threadedly connected to the screw component and the sealing component respectively.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] First, the design of the new injection head structure makes it easy to disassemble, and the internal pipes can be cleaned or replaced separately. This greatly simplifies the operation process of cleaning and replacing the injection head, reducing the time and energy cost of the staff. Secondly, the new injection head is designed as a regular and easy-to-disassemble structure, so that the staff can easily disassemble its internal pipes separately for cleaning. Compared with traditional injection heads, the cleaning difficulty is greatly reduced, effectively reducing the difficulties and obstacles in the cleaning process. Furthermore, the downtime caused by blockage of the injection head, as well as the time and labor costs required for cleaning and replacing the injection head, are reduced, thereby improving production efficiency. The staff can carry out production and maintenance work more efficiently, increasing the operating time and production capacity of the production line.

[0008] In general, the technical effect of the utility model is that it simplifies the process of cleaning and replacing the injection molding head, reduces the difficulty of cleaning, and at the same time improves production efficiency, providing strong support for the stable operation and continuous production of the injection molding machine.

[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0019] like Figures 1 to 8 As shown, an easily detachable injection molding head for an injection molding machine includes an injection molding head body 1, a heating component 2, a screw connection component 3, a sealing component 4 and a main body component 5.

[0020] An elastic ring 11 is fixedly connected to the inner wall of one end of the injection head body 1, and a diaphragm plate 12 is fixedly arranged at the other end. A mounting slot 13 is opened in the middle of the diaphragm plate 12. The mounting slot 13 is a special-shaped hole composed of a round hole 131 and a waist-shaped hole 132, which is used to install the heating component 2 and the screw component 3.

[0021] The heating assembly 2 includes a mounting slot column 21 fixedly connected to the inner wall of the injection head body 1, the outer diameter of the mounting slot column 21 is smaller than the outer diameter of the circular hole 131 of the mounting slot hole 13, the inner diameter of the through slots at both ends is larger than the outer diameter of the inner tube 51, and the inner wall of the mounting slot column 21 is fixedly connected with a fixing block 22 in a layered circular array, and the inner wall of the fixing block 22 is fixedly connected with a heating coil 23. When the injection molding work is performed, the heating coil 23 is started, and the heating coil 23 can heat the inner tube 51, so that the injection molding material flowing through the inner tube 51 will not cool down quickly, thereby improving the injection molding effect of the injection molding machine.

[0022] The screw connection component 3 includes a fixed ring plate 32 on the inner wall at one end, the outer diameter of the fixed ring plate 32 is smaller than the outer diameter of the waist-shaped hole 132 of the mounting slot 13, and a threaded groove column 31 is fixedly connected to the outer wall of one side of the fixed ring plate 32, and the groove column 31 is provided with an internal thread for threaded connection to the main body component 5.

[0023] The sealing assembly 4 includes a first fixing ring 41 fixedly connected to the outer wall at one end, and an elastic sealing gasket 42 fixedly connected to the outer wall of the first fixing ring 41. The sealing gasket 42 matches the slot 52 of the fixing plate 53. When connected, the elastic sealing gasket 42 is clamped on the inner wall of the slot 52.

[0024] The main body component 5 includes an inner tube 51 and a fixing plate 53. An external thread 54 is provided at one end of the inner tube 51 to match the internal thread of the groove column 31. The fixing plate 53 is sleeved on the thread 54. A slot 52 is also provided on the side wall of one side of the fixing plate 53 for clamping the sealing gasket 42 of the sealing component 4.

[0025] Embodiment: During installation, the heating component 2 and the screw component 3 are sequentially inserted through the mounting slot 13 into the inner wall of the cavity of the injection head body 1, and the first fixing ring 41 of the sealing component 4 is pressed against the diaphragm baffle 12 of the injection head body 1. One end of the smooth surface of the main component 5 sequentially passes through the sealing component 4, the mounting slot 13 of the injection head body 1, the center hole of the screw component 3 and the center hole of the heating component 2. When the thread 54 of the inner tube 51 corresponds to the threaded opening of the threaded groove column 31 of the screw component 3, the inner tube 51 is rotated so that the external thread 54 on one side of the fixing plate 53 is threadedly engaged with the internal thread on the inner wall of the threaded groove column 31 until the inner tube 51 passes through the elastic ring 11. It should be noted here that when the inner tube 51 is inserted into the inner wall of the elastic ring 11, the elastic ring 11 will be in a state of being squeezed and deformed; at this time, the fixing plate 53 of the injection head body 1 is tightened until the inner wall of the card groove 52 on the fixing plate 53 is sealed and the elastic sealing pad 42 is stopped from rotating. Finally, the injection head body 1 is installed into the injection molding machine, and the equipment can be operated normally.

[0026] When the injection head needs to be cleaned or replaced, the injection head body 1 is unscrewed, and then the inner tube 51 is rotated so that the external thread 54 on the inner tube 51 is disengaged from the internal thread of the thread groove column 31. At this time, the inner tube 51 can be removed for replacement or cleaning, and the cleaned or replaced inner tube 51 is inserted into the interior of the injection head body 1 and the above steps are repeated to complete the installation.
