[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] Please see Figures 1 to 4 As shown, the technical solution provided by this utility model is a multi-color blending heat-sensitive screw, including a multi-color injection molding machine screw 1 and a screw head 3. It uses the corresponding screw structure of the barrel configuration of the existing Haitian injection molding machine's second-generation dual-color dual-alloy model 160T26 Changfeiya.

[0020] This application addresses the issue that the existing Shanghai Tian injection molding machine's second-generation dual-color, dual-alloy injection molding machine uses a screw with a barrel configuration of the 160T26 Changfeiya model. In actual use, due to the fixed structure of this screw model, maintenance is inconvenient, and the head and tail ends are particularly prone to damage and replacement, causing inconvenience. The screw head and tail end structure in this application is rationally designed, facilitating installation on the head and tail ends of multi-color injection molding machine screws, simplifying replacement, and improving efficiency.

[0021] This application addresses the issue of insufficient durability in existing screw material structures, and improves the durability and service life of screw material structures.

[0022] The innovation of this application lies in the following: The front end of the multi-color injection molding machine screw 1 is provided with a connecting end 11, the screw head 3 is screwed onto the connecting end 11, and the rear end of the screw head 3 is provided with a stud 31. The connecting end 11 is fitted with an internal threaded hole 12 for screwing the stud 31. This facilitates screwing onto the screw head 3 and makes maintenance and replacement convenient. The connecting end 2 13 is connected to the rear end of the multi-color injection molding machine screw 1 via a threaded portion. This facilitates screwing onto the tail end 2 and makes maintenance and replacement convenient. The rear end of the multi-color injection molding machine screw 1 is provided with a connecting end 2 13, and the tail end 2 is screwed onto the connecting end 2 13. The tail end 2 includes a tail end 21 and a tail end 22, which are connected by a connecting post 23. The structure is reasonable, and the tail end 21 has internal threads, which are screwed onto the rear end of the connecting end 2 13. This facilitates maintenance and replacement.

[0023] The screw, screw head, and screw tail of the multi-color injection molding machine are all made of biaxial alloy. The biaxial alloy is a mixture of nickel-titanium alloy, copper-zinc-aluminum alloy, and copper-zinc-manganese alloy. Biaxial alloys possess biaxial shape memory effect and excellent mechanical properties, including high elastic modulus, high strength, good toughness, and fatigue life. Biaxial alloys have good wear resistance, capable of withstanding various cutting and abrasive forces, and are not easily worn or deformed. Biaxial alloys also have good corrosion resistance, capable of withstanding corrosion from various strong acids, strong alkalis, and other corrosive media, and are not easily rusted or discolored.

[0024] Working principle: The multi-color injection molding machine screw has a connecting end one at the front end, and the screw head is screwed onto connecting end one. Connecting end two is connected to the rear end of the multi-color injection molding machine screw via a threaded part. Connecting end two has a tail end screwed on. This facilitates maintenance and replacement. In addition to improving the screw structure, this application also improves the screw material structure, resulting in a longer screw service life, simpler installation, and easier multi-color blending operations.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
