Description

Technical Field

[0001] This utility model relates to the field of injection molding machine nozzle treatment technology, specifically to an injection molding machine nozzle cleaning device. Background Technology

[0002] During use, if the nozzle temperature of an injection molding machine is too high, the viscosity of the molten plastic will decrease, resulting in excessive fluidity. This makes the molten plastic more likely to flow out of the nozzle and adhere to its surface. Conversely, if the temperature is too low, the molten plastic may cool and solidify at the nozzle, forming lumps and causing material sticking. Therefore, it is necessary to clean the injection molding machine nozzles regularly. In existing technology, workers need to use a scraper to scrape off the sticky material from each nozzle one by one to avoid affecting the normal use of the injection molding machine nozzles. However, the cleaning speed is slow, and workers need to process many nozzles one by one, which can easily lead to omissions. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a nozzle cleaning device for injection molding machines. By cooperating with the nozzle assembly and the cleaning assembly, the device can quickly scrape and clean the distributed nozzle bodies during use, preventing material from adhering around the nozzles. This eliminates the need for users to clean each nozzle individually, avoids omissions, and improves cleaning efficiency.

[0030] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] This utility model provides a nozzle cleaning device for injection molding machines. Through the cooperation of the nozzle assembly and the cleaning assembly, the device can quickly scrape and clean the distributed nozzle bodies during use, preventing material from adhering around the nozzles. This eliminates the need for users to clean each nozzle individually, avoids omissions, and improves cleaning efficiency.

[0033] Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shown is an overall structural schematic of one embodiment of the nozzle cleaning device for injection molding machines according to this utility model. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The main structure of this embodiment includes: an injection molding machine nozzle assembly and a material clearing assembly.

[0034] The injection molding machine nozzle assembly is used in conjunction with the cleaning assembly. Specifically, the injection molding machine nozzle assembly includes an injection molding machine nozzle body 11, an electric telescopic rod 13 fixed to the side wall of the injection molding machine nozzle body 11, and a concave mounting bracket 12 connected to the top surface of the electric telescopic rod 13.

[0035] In practical use, the material clearing assembly is installed and used based on the injection molding machine nozzle body 11, the concave mounting bracket 12, and the electric telescopic rod 13.

[0036] The cleaning assembly is used for centralized cleaning of the injection molding machine nozzle body 11. Specifically, the cleaning assembly includes a mounting plate 21 disposed between concave mounting brackets 12, an electric rotating shaft 22 connecting the mounting plate 21 and the concave mounting brackets 12, an L-shaped plate 23 fixed to the bottom surface of the mounting plate 21, a cylinder 24 disposed on the bottom surface of the L-shaped plate 23, a rotary motor 25 connected to the output end of the cylinder 24, a disc 26 connected to the output end of the rotary motor 25, a curved frame 27 fixed to the disc 26, and a scraper 28 connected to the surface of the curved frame 27.

[0037] In practical use, the electric telescopic rod 13 drives the concave mounting bracket 12 and the L-shaped plate 23 to flip, and the electric telescopic rod 13 drives the concave mounting bracket 12 to move. The cylinder 24 pushes the rotary motor 25 to move upward until the scraper 28 is in contact with the outer wall of the injection molding machine nozzle body 11. At this time, the rotary motor 25 drives the disc 26 to rotate. In this way, the scraper 28 rotates around the injection molding machine nozzle body 11 once, which can realize the cleaning of the material. This eliminates the need for the user to clean the material one by one, greatly improving the efficiency of cleaning.

[0038] Furthermore, it also includes a receiving assembly, which includes an externally threaded cylinder 41 fixed to the surface of the L-shaped plate 23; wherein the externally threaded cylinder 41 is fitted onto the outside of the cylinder 24; the receiving assembly also includes an internally threaded cylinder 42 disposed below the cylinder 24 and a receiving plate 43 fixed to the internally threaded cylinder 42; wherein the externally threaded cylinder 41 and the internally threaded cylinder 42 are connected to each other; the receiving plate 43 has a circular groove 44, and the circular groove 44 is directly opposite to the injection port of the injection molding machine nozzle body 11;

[0039] In practical use, the external threaded cylinder 41 and the internal threaded cylinder 42 are connected to each other, so that the waste scraped by the scraper 28 will fall directly into the circular groove 44. In this way, the scraped waste will not fall onto the bottom surface. After cleaning, when the L-shaped plate 23 is flipped and moved, the waste can be directly poured into the external storage bucket for centralized processing.

[0040] Furthermore, it also includes a replacement component, which includes a curved groove 31 formed on the surface of the curved frame 27 and a curved plate 32 inserted into the curved groove 31; wherein the curved plate 32 is fixed to the scraper 28; the replacement component also includes a circular hole 33 formed on the surface of the curved frame 27.

[0041] In practical use, the curved plate 32 is also provided with corresponding holes, and the curved plate 32 can be locked by passing through the round hole 33 and the hole through the threaded rod. This structural design makes it easy to replace the scraper 28 and select the appropriate scraper 28.

[0042] Furthermore, a round rod 261 is fixed at the very center of the disc 26, and the round rod 261 is directly opposite the injection port of the injection molding machine nozzle body 11;

[0043] In actual use, during the upward movement of the rotary motor 25, the round rod 261 will be directly inserted into the hole of the injection molding machine nozzle body 11. In this way, the round rod 261 will rotate along the hole of the injection molding machine nozzle body 11, thus avoiding the problem of accidental shaking and displacement of the scraper 28 during the cleaning process and improving the stability of the scraper 28 operation.

[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
