[0031] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] The following is combined with Figure 1-5 The finishing device for fluidized plastic material after injection molding of the present invention is further described.

[0033] Please focus on Figure 1-3 The present invention discloses a finishing device for fluidized material after injection molding, comprising a first scraper assembly 100, a water spray assembly, and a second scraper assembly 200, which are arranged in parallel and spaced apart. The first scraper assembly 100 and the second scraper assembly 200 have the same structure; the first scraper assembly 100 comprises a scraper shaft 001 and a scraper body 002 arranged on one side of the scraper shaft 001, the scraper body 002 is rotatably connected to the scraper shaft 001, and the scraper body 002 is also connected to the scraper shaft 001 via a torsion spring assembly, which includes a torsion spring retainer. Block and torsion spring body 003, the torsion spring body 003 is sleeved on the scraper shaft 001, the torsion spring stop block includes a connected fixed plate 004 and a baffle 005, the fixed plate 004 is installed on the scraper shaft 001, the baffle 005 is located on one side of the fixed plate 004, and one protruding end of the torsion spring body 003 is inserted into the baffle 005; the other protruding end of the torsion spring body 003 is in contact with the scraper body 002, for providing pressure to the scraper body 002; the water spray assembly includes a spray rod 006 and a plurality of nozzles 007 arranged at intervals on the spray rod 006.

[0034] The polishing device for post-injection molding of fluidized materials of the present invention is used to continuously polish the surface of a viscous mixture having a fluidized state after being extruded into a viscous material injection molding mold 300 by pouring. The first scraper assembly 100 and the second scraper assembly 200 form two front and back scraping and polishing processes. The first scraper assembly 100 is primarily used to level the material above the mold, and the water spray assembly is used to spray water mist to moisten the upper surface of the building product after the first leveling. The second scraper assembly 200 then performs a second scraping to smooth the upper surface of the building product and achieve a finishing effect. Therefore, the polishing device for post-injection molding of fluidized materials of the present invention can continuously perform leveling and polishing operations on building products, effectively improving the smoothness and flatness of the upper surface of the building product and improving the surface quality of the building product.

[0035] According to a specific embodiment of the present invention, the first scraper assembly 100 includes two sleeves 008, which are respectively fixed to the two ends of the scraper body 002. The sleeves 008 are sleeved on the scraper shaft 001 to realize the rotation connection between the scraper body 002 and the scraper shaft 001.

[0036] In this embodiment, sleeve 008 is annular, while scraper shaft 001 is cylindrical. This design creates a simple and reliable hinged structure. When the scraper body 002 rotates sleeve 008, the contact surface between sleeve 008 and scraper shaft 001 is flat, providing excellent wear resistance and stability. This ensures reliable operation even after repeated scraping.

[0037] According to a specific embodiment of the present invention, the torsion spring assembly comprises two sets that are spaced apart.

[0038] In this embodiment, each scraper assembly is equipped with a set of torsion spring assemblies at both ends, which can apply pressure to the scraper body 002 from both ends. The combined pressure creates a greater pressure to ensure the scraping effect. The structure of applying force at both ends also improves stability.

[0039] According to a specific embodiment of the present invention, two sleeves 008 are provided between two torsion spring assemblies.

[0040] In this embodiment, during assembly, when the scraper shaft 001 and the sleeve 008 are free, the sleeve 008 is first inserted to form a structure in which the sleeve 008 is rotatably connected to the scraper shaft 001, and then the torsion spring assembly is installed. This structure facilitates the assembly and disassembly of the device.

[0041] According to a specific embodiment of the present invention, the scraper body 002 is installed obliquely on one side of the scraper shaft 001 , the nozzle 007 is installed obliquely, and the oblique direction of the nozzle 007 is consistent with the oblique direction of the scraper body 002 .

[0042] More specifically, the scraper body 002 includes a scraping state. When the scraper body 002 is in the scraping state, the angle between the scraper body 002 and the horizontal plane is 25° to 45°.

[0043] In this embodiment, both scraper bodies 002 are installed at an angle, which facilitates scraping. The inclination of the nozzle 007 aligns with that of the scraper bodies 002. This configuration facilitates the nozzle 007 to spray water toward the rear end of the scraping direction without affecting the scraping of the preceding scraper body 002. Furthermore, the water mist sprayed from the nozzle partially diffuses within the scraper body 002 of the second scraper assembly 200, preventing the second scraper body 002 from sticking to the material and further improving the finishing effect.

[0044] Please focus on Figure 4According to a specific embodiment of the present invention, a stopper mounting hole 009 is provided on the fixing plate 004, the scraper shaft 001 passes through the stopper mounting hole 009, and the baffle rod 005 is provided with a strip-shaped slot 010 passing through it, one end of the strip-shaped slot 010 is open, and an extended end of the torsion spring body 003 is inserted into the strip-shaped slot 010.

[0045] In this embodiment, the structure of the block mounting hole 009 is adopted, which is conducive to quickly putting the fixing plate 004 on the scraper shaft 001, pushing one protruding end of the torsion spring body 003 into the strip slot 010 from the opening at one end of the strip slot 010, and using the strip slot 010 to clamp the protruding end of the torsion spring body 003.

[0046] More specifically, a stopper anti-rotation flat surface (not shown) is provided on the inner wall of the stopper mounting hole 009, and a shaft anti-rotation flat surface is provided on the scraper shaft 001 at the position corresponding to the stopper anti-rotation flat surface. This structure facilitates the rapid installation of the torsion spring stopper, prevents relative rotation between the torsion spring stopper and the scraper shaft 001, and ensures the stability of the connection between the extended end of the torsion spring body 003 and the stopper rod 005.

[0047] According to a specific embodiment of the present invention, a side of the scraper body 002 close to the torsion spring body 003 is provided with a concave rectangular avoidance notch 011.

[0048] In this embodiment, the rectangular avoidance gap 011 is used to provide necessary space for the installation of the torsion spring body 003 to avoid interference.

[0049] According to a specific embodiment of the present invention, a finishing device for fluidized material after injection molding is arranged above the viscous material injection molding mold 300. The viscous material injection molding mold 300 includes slag-filled cavities distributed in a rectangular array. A slag collecting box 012 is provided on one side of the slag-filled cavity, and a material collection port is provided on the top of the slag collecting box 012.

[0050] In this embodiment, a slag collecting box 012 is provided at the position where the scraping ends, which can ensure that the waste scraped by the scraper body 002 directly falls into the slag collecting box 012, making it convenient to clean up the waste on site.

[0051] More specifically, when the scraper body 002 is in the scraping state, the lower portion of the scraper body 002 is in contact with the upper surface of the viscous material injection molding die 300 , and the height of the collection port is lower than the height of the upper surface of the viscous material injection molding die 300 .

[0052] In this embodiment, by adopting this structure, the scraped excess material falls directly into the slag collecting box 012 from the upper surface of the mold through the collecting opening, thereby ensuring the material collection effect.

[0053] Figure 5This is a real-life application diagram of the present invention. Through actual application, it can be seen that a better finishing effect can be achieved on the surface of building products.

[0054] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium; it can mean internal communication between two elements, or a "transmission connection," i.e., a power connection through various appropriate means such as a belt drive, a gear drive, or a sprocket drive. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
