[0024] Please see Figure 1 and Figure 2 This utility model provides a spade for 3D printing mold taking, which includes a spade head 100 and a spade handle 200. The spade head 100 includes a first spade surface 110 and a second spade surface 120, which are connected at an angle, i.e., the second spade surface 120 is inclined relative to the first spade surface 110. The end of the second spade surface 120 away from the first spade surface 110 is wavy. The spade handle 200 is fixedly connected to the end of the first spade surface 110 away from the second spade surface 120, and a magnet block 300 is provided inside the spade handle 200. Here, the angle between the first spade surface 110 and the second spade surface 120 is not limited and can be adaptively adjusted according to actual needs. In this application, the inclined arrangement of the second spade surface 120 relative to the first spade surface 110 facilitates the spade head 100 to extend into the bottom of the model, and the wavy edge not only reduces damage to the printing platform but also avoids scratching the operator. Meanwhile, the magnet block 300 inside the handle 200 can attach the scraper to the printer casing for easy storage.

[0025] Please see Figure 2 and Figure 3 In one embodiment, the end of the second shovel surface 120 facing away from the first shovel surface 110 has a wedge-shaped structure, meaning the edge of the second shovel surface 120 is sloped. This facilitates the insertion of the second shovel surface 120 between the model and the printing platform. Furthermore, the sloped edge decomposes the applied horizontal force into horizontal and vertical components, effectively pushing the model away and lifting it from the printing platform. The angle of the slope of the second shovel surface 120 is not limited and can be adjusted adaptively according to actual needs. In this embodiment, the inclination direction of the wedge-shaped slope is opposite to the inclination direction of the second shovel surface 120.

[0026] Please see Figure 1 and Figure 2 The shovel head 100 and the shovel handle 200 can be fixedly connected in any way, such as by bolting, riveting, or snap-fitting, as long as the shovel head 100 and the shovel handle 200 can be fixedly connected. In one embodiment, the shovel head 100 and the shovel handle 200 are integrally formed or plug-in connected. In this application, the shovel head 100 is made of metal or plastic, and the shovel handle 200 is made of plastic. When the shovel head 100 is made of metal and the shovel handle 200 is made of plastic, the shovel head 100 and the shovel handle 200 are plug-in connected. For example, one of the shovel head 100 and the shovel handle 200 is provided with a protrusion, and the other of the shovel head 100 and the shovel handle 200 is provided with a groove adapted to the protrusion. The protrusion extends into the groove and the protrusion and the groove are interference-fitted, thereby achieving a fixed connection between the shovel head 100 and the shovel handle 200. When both the shovel head 100 and the shovel handle 200 are made of plastic, the shovel head 100 and the shovel handle 200 are integrally formed. In this embodiment, both the shovel head 100 and the shovel handle 200 are made of acrylonitrile-butadiene-styrene copolymer (ABS), and the shovel head 100 and the shovel handle 200 are integrally molded. Exemplarily, the shovel head 100 and the shovel handle 200 are integrally molded using an injection molding process. It should be noted that injection molding is widely used in the industry, and will not be elaborated upon further here.

[0027] Please see Figure 1 and Figure 2In one embodiment, the shovel handle 200 is provided with a receiving cavity 210 for placing a magnet block 300, and the magnet block 300 is interference-fitted with the receiving cavity 210. In this embodiment, the magnet block 300 is externally covered with a plastic layer. Exemplarily, the plastic layer is coated on the surface of the magnet block 300 by injection molding. In this embodiment, the material of the plastic layer is the same as that of the shovel handle 200, which is an acrylonitrile-butadiene-styrene copolymer. When the magnet block 300 is installed, the plastic layer is ensured to be interference-fitted with the receiving cavity 210. Plastics generally have a high elastic modulus and good deformation recovery ability. When the receiving cavity 210 and the plastic layer are interference-fitted, the receiving cavity 210 and the plastic layer will generate uniform contact pressure through elastic deformation, forming a large frictional force. The bidirectional elastic deformation of the receiving cavity 210 and the plastic layer can more effectively maintain the interference amount. Furthermore, the surface of the injection-molded plastic layer often has a microscopic uneven structure. During interference fit, these rough surfaces interlock with each other, forming a mechanical interlocking effect, further resisting separation and effectively preventing the magnet block 300 from falling out of the receiving cavity 210. This application does not limit the specific material of the magnet block 300, as long as it satisfies the requirement of being able to attach the spatula to the printer's casing. For example, the magnet block 300 is made of neodymium iron boron magnet.

[0028] Please see Figure 1 and Figure 2 In one embodiment, the grip section of the shovel handle 200 is provided with anti-slip textures, which are distributed in a circular array on the grip section of the shovel handle 200. The anti-slip textures can effectively increase the surface roughness of the shovel handle 200, significantly improve the coefficient of friction between the hand and the shovel handle 200, and prevent the hand from slipping due to sweat, oil, or a humid environment. The shovel handle 200 is shaped to fit the index finger and thumb of the hand. From the end of the shovel handle 200 connected to the shovel head 100 to the end of the shovel handle 200 away from the shovel head 100, the width of the shovel handle 200 first decreases, then increases, and then decreases again. The narrowing of the end of the shovel handle 200 near the shovel head 100 can reduce grip resistance, the moderate widening in the middle section strengthens the fulcrum for force application, and the end of the shovel handle 200 away from the shovel head 100 narrows again to form an anti-slip grip point. The shovel handle 200 as a whole forms an ergonomically shaped wave-shaped curved surface transition.

[0029] Please see Figure 1 In one embodiment, the width of the shovel head 100 gradually decreases from the end away from the shovel handle 200 to the end connected to the shovel handle 200, meaning the shape of the shovel head 100 is trapezoidal. The wider end of the shovel head 100 used to remove the model increases the contact area between the shovel head 100 and the model, reducing the number of repetitive operations and improving work efficiency. Simultaneously, the trapezoidal structure of the shovel head 100 enhances its structural stability, and the gradually decreasing width near the shovel handle 200 prevents breakage due to localized stress concentration.

[0030] This utility model discloses a spatula for 3D printing mold taking. The spatula head is fixedly connected to the spatula handle and includes a first spatula surface and a second spatula surface. The first spatula surface and the second spatula surface are connected at an angle, and the end of the second spatula surface facing away from the first spatula surface is wavy. A magnet is installed inside the spatula handle. The angled connection between the second spatula surface and the first spatula surface facilitates the insertion of the spatula head into the bottom of the model, and the wavy edge of the second spatula surface reduces damage to the printing platform. At the same time, the magnet inside the spatula handle can attract the spatula to the printer casing for easy storage. Therefore, this utility model effectively overcomes some practical problems in the prior art and has high utilization value and significance.

[0031] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
