Description

Technical Field

[0001] This utility model relates to the field of plastic model cutting tools, and in particular to a plastic model chamfering scraper. Background Technology

[0002] Plastic models are made by injection molding multiple parts onto a single injection-molded sheet. Users receive the sheet, cut out the parts sequentially, and then assemble them to create the final model. Originally common as children's educational toys, plastic models have evolved into sophisticated and realistic high-end decorative items with the development of industrial technology. In recent years, they have begun to gain popularity among young people and even middle-aged individuals. Among the most popular are Gundam models, which, depending on their level of detail, can have anywhere from dozens to thousands of parts, falling into the category of high-end plastic models and enjoying great popularity among DIY model enthusiasts.

[0003] With the rise of the plastic model industry, many DIY model enthusiasts are not satisfied with the precision of the plastic models that come out of the factory. For example, due to injection molding errors, individual parts may have irregular textures or rounded corners, or due to limitations in the injection molding process, the textures on the parts may lack a sense of layering or three-dimensionality. Therefore, users need to perform secondary processing on the plastic parts they purchase, which is why plastic model cutting tools began to appear.

[0004] Based on the user demand for high-quality model making, plastic model cutting tools differ from traditional wood carving, stone carving, or utility knives. They need to adapt to the moderate hardness of plastic, and their blades exhibit different shapes depending on their uses. For example, scribing knives and scrapers require precision, ease of operation, no burrs, and a smooth feel when working on plastic. At the same time, plastic models have small parts, and larger cutting tools from other fields cannot be used. Plastic model cutting tools are specialized tools.

[0005] Currently, there is no tool on the market specifically designed for trimming the edges and corners of plastic model prototypes. Utility Model Content

[0006] This utility model provides a plastic model chamfering scraper, which aims to solve the problem that the existing plastic model industry lacks a tool for trimming the edges and corners of plastic model prototypes.

[0007] According to an embodiment of this application, a plastic model chamfering scraper is provided, including a blade head and a handheld part, the blade head and the handheld part being connected; the blade head includes a cutting edge and a stabilizing rod, one end of the cutting edge is connected to the handheld part, and the other end of the cutting edge is connected to the stabilizing rod; the cutting edge includes a scraping surface, the stabilizing rod extending from the end of the scraping surface away from the handheld part, and the angle formed between the scraping surface and the stabilizing rod is greater than 90 degrees.

[0008] Preferably, the surface of the stabilizer bar on the same side as the scraping surface is an outwardly convex arc surface.

[0009] Preferably, the height of the highest point of the arc surface of the stabilizer bar is equal to the height of the scraping surface at the connection point between the blade and the stabilizer bar.

[0010] Preferably, the stabilizing bar is arranged on the same straight line as the surface of the blade on that side and the outer surface of the handpiece on the side away from the scraping surface.

[0011] Preferably, the handle has a beveled portion at one end near the blade, the beveled portion being a beveled structure formed between the surfaces on both sides of the scraping surface and the handle.

[0012] Preferably, the scraped surface is a linear surface.

[0013] Preferably, the scraping surface is a concave curved surface.

[0014] Preferably, the length of the blade head in the direction corresponding to the axis of the handheld part is 6mm to 7mm.

[0015] Preferably, the handheld part is integrally formed and connected to the blade; and / or the blade is integrally formed and connected to the stabilizer bar.

[0016] Preferably, the angle formed between the scraping surface and the stabilizing bar is in the range of greater than 90 degrees and less than 180 degrees.

[0017] Compared with the prior art, the plastic model chamfering scraper provided by this utility model has the following beneficial effects: By designing a chamfering scraper for plastic models, a stabilizing bar extends from the tip of the blade, and the scraping surface of the blade forms an obtuse angle with the stabilizing bar. This allows the user to support the part against its outer surface during scraping, while the scraping surface creates a chamfer at the corners. This effectively removes irregularities, uneven edges, burrs, and other imperfections from the initial shape of the plastic model. Furthermore, the scraper is easy to use, and the resulting chamfer makes the model appear more three-dimensional and refined, repairing edges and adding detail, thus enhancing the three-dimensionality of the parts.

[0021] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0023] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0024] Please combine Figure 1 and Figure 2 The first embodiment of this utility model discloses a plastic model chamfering scraper, including a blade head 1 and a handheld part 2. The blade head 1 and the handheld part 2 are connected, and the user operates the blade head 1 to scrape on the model by holding the handheld part 2.

[0025] The blade head 1 includes a blade 11 and a stabilizing rod 12. One end of the blade 11 is connected to the handheld part 2, and the other end of the blade 11 is connected to the stabilizing rod 12. The blade 11 includes a scraping surface 111 for scraping plastic models. The stabilizing rod 12 extends from the end of the scraping surface 111 away from the handheld part 2, and the angle formed between the scraping surface 111 and the stabilizing rod 12 is greater than 90 degrees.

[0026] It is understandable that when the user is using it, the stabilizer bar 12 is used to hold the outer side of the part, and the scraping surface 111 is aligned with the corner of the part that needs to be processed, and the corner of the part is gradually ground into a chamfered structure.

[0027] It is understood that the angle formed between the scraping surface 111 and the stabilizing rod 12 is greater than 90 degrees (e.g., Figure 2 As shown in angle a), that is, when the stabilizer 12 abuts against the outer side of the part, the scraping surface 111 is inclined, and the scraped corner of the part can form a chamfer structure. In this embodiment, the angle formed between the scraping surface 111 and the stabilizer 12 is in the range of greater than 90 degrees and less than 180 degrees, specifically 120 degrees, 135 degrees or 150 degrees, and scraping surfaces 111 with different angles can be made according to different needs.

[0028] It is understood that in this embodiment, the scraping surface 111 is a linear surface, which can form a chamfer after scraping. Specifically, if the user scrapes lightly once, a linear chamfer is formed, which can be simply used for deburring. If the user scrapes repeatedly, a larger, smooth beveled chamfer is formed.

[0029] Alternatively, in other embodiments, the scraping surface is a concave curved surface, which leaves a rounded chamfer structure when the user scrapes.

[0030] It is understood that the width of the scraping surface is 0.7mm, or in other embodiments, 0.5mm, 0.6mm, 0.8mm, etc. The length of the blade head 1 in the direction corresponding to the axis of the handheld part 2 is 6mm to 7mm (e.g., Figure 2 (as shown in dimension b). In this embodiment, the lengths of the stabilizer 12 and the blade 11 in the direction corresponding to the axis of the handheld part 2 are 7 mm, the length of the blade 11 in this direction is 4 mm, and the length of the stabilizer 12 in this direction is 3 mm.

[0031] Please continue reading. Figure 1 The stabilizer bar 12 has an outwardly convex arc-shaped surface structure on the same side as the scraping surface 111. This arc-shaped surface structure allows the scraping surface 111 to move more smoothly during scraping when the stabilizer bar 12 is against the outer side of the part, reducing the resistance caused by friction at the stabilizer bar 12 position. At the same time, the arc-shaped area of ​​the stabilizer bar 12 contacts the surface of the part, effectively protecting the contact area and preventing scratches.

[0032] Please see Figure 2The height of the highest point of the arc surface of the stabilizer 12 is equal to the height of the scraping surface 111 at the connection between the blade 11 and the stabilizer 12, so that there is no height difference between the stabilizer 12 and the end of the scraping surface 111, and the connection structure is smoothly transitioned. This reduces the accidental damage to the positioning edge of the part by the end of the scraping surface 111 during the positioning process by the user through the stabilizer 12, effectively protects the integrity of the outer surface of the part, and improves the user experience.

[0033] Please continue reading. Figure 2 The stabilizer bar 12 is positioned on the side away from the scraping surface 111, and is aligned with the surface of the blade 11 on that side and the outer surface of the handheld part 2. In other words, the stabilizer bar 12 is eccentrically positioned and edge-mounted, so that the back of the stabilizer bar 12 is flush with the back of the blade and the outer surface of the handheld part. This reduces various types of steps and edges on the tool due to different structures, and can further reduce accidental damage to parts during operation or movement, thus protecting the integrity of the parts.

[0034] Please continue reading. Figure 1 The handle 2 has a beveled section 21 at one end near the blade 11. The beveled section 21 is a sloped structure formed between the surfaces on both sides of the scraping surface 111 and the handle 2. The beveled section 21 can be used to create clearance, providing space in plastic (rubber) models and facilitating operation of the blade in confined spaces. At the same time, the beveled section 21 creates a curved transition between the blade 11 and the handle 2, reducing sharp corners and edges on the blade body while creating a smooth visual effect and enhancing the aesthetics of the blade.

[0035] The handle 2 is integrally formed and connected to the blade 11, and the blade 11 is integrally formed and connected to the stabilizing rod 12. That is, the chamfering scraper provided in this embodiment can be made of the same material, or the handle 2 and blade 11 can be made of different materials. For example, the handle can be made of wood and inserted and fixed to the tail of the blade 11. The blade 11 and stabilizing rod 12 can be integrally formed of the same material, or the stabilizing rod 12 can be welded or bonded to the end of the blade 11 using different materials. In this embodiment, the handle 2, blade 11, and stabilizing rod 12 are integrally formed and connected. Specifically, the handle 2, blade 11, and stabilizing rod 12 can be made of tungsten steel, ceramic, powder metallurgy steel, etc., without specific limitations, as long as they can scrape plastic parts.

[0036] Compared with the prior art, the plastic model chamfering scraper provided by this utility model has the following beneficial effects: By designing a chamfering scraper for plastic models, a stabilizing bar extends from the tip of the blade, and the scraping surface of the blade forms an obtuse angle with the stabilizing bar. This allows the user to support the part against its outer surface during scraping, while the scraping surface creates a chamfer at the corners. This effectively removes irregularities, uneven edges, burrs, and other imperfections from the initial shape of the plastic model. Furthermore, the scraper is easy to use, and the resulting chamfer makes the model appear more three-dimensional and refined, repairing edges and adding detail, thus enhancing the three-dimensionality of the parts.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
