Description

Technical Field

[0001] This utility model relates to the field of 3D printing mold technology, and in particular to a 3D printed rose petal mold with biomimetic texture. Background Technology

[0002] In recent years, with the development of high-precision 3D printing technology (such as DLP photopolymerization and SLS nylon sintering), combined with biomimetic texture modeling technology, it is possible to achieve biomimetic textures of rose petals on the surface of molds. Existing petal molds typically use upper and lower molds to form a cavity, and then injection molding is performed into the cavity. However, some material usually gets into the gap between the upper and lower molds, causing burrs on the edges of the petals, which seriously affects the appearance and feel of the petals. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a 3D-printed rose petal mold with biomimetic texture. The process involves placing material into a cavity, extruding it between a lower mold body and an upper mold body to form a petal model, and having a cutting body move towards the lower mold body to cut away burrs along the edges of the petals. This method is simple, efficient, safe, reliable, and easy to operate.

[0004] This utility model is achieved through the following technical solution: a 3D printed rose petal mold with biomimetic texture is provided, including a lower mold body and an upper mold body, each having a cavity; a cut surface extending along the edge of the cavity is provided on the lower mold body, with the cut surface perpendicular to the side of the lower mold body where the cavity is located; the edge of the upper mold body is adapted to the edge of the cavity, and a cutting body adapted to the cut surface slides on the upper mold body; by placing material into the cavity, the lower mold body and the upper mold body are pressed together to form a petal model, and the cutting body moves toward the lower mold body and cooperates with the cut surface to cut the burrs on the edge of the petal.

[0005] As an optimization, the lower mold body is provided with a slide bar parallel to the cutting surface, and the cutting body slides on the slide bar; the slide bar guides the cutting body to prevent the cutting body from being misaligned and making it difficult to clean the burrs on the edge of the petals.

[0006] As an optimization, the distance between the cutting body and the lower mold body is greater than the distance between the upper mold body and the lower mold body, and the cutting body and the upper mold body are connected by a return spring; the return spring causes the cutting body and the upper mold body to automatically separate, thereby automatically cleaning the burrs on the edge of the petals when the petals are formed.

[0007] As an optimization, a support is fixed on the upper mold body, and the distance between the support and the lower mold body is equal to the distance between the upper and lower mold bodies; the support supports the upper mold body, thereby controlling the distance between the upper and lower mold bodies and preventing the cavity from deforming under the pressure of the upper and lower mold bodies.

[0008] As an optimization, a positioning groove is provided on the lower mold body, extending vertically toward the side of the lower mold body where the cavity is located, and the bracket slides through the positioning groove; the positioning groove is used to position the bracket and prevent the bracket and the upper mold body from shifting.

[0009] As an optimization, a cutting blade extending along the edge of the cavity is fixed on the cutting body; the petals are cut by the cutting blade to prevent the cutting body from being damaged during long-term operation, thus making it difficult to effectively clean the burrs on the edge of the petals.

[0010] As an optimization, liquid infusion channels are respectively opened in the lower mold body and the upper mold body, and the liquid infusion channels in the lower mold body and the upper mold body surround the cavity; the liquid transported through the liquid infusion channels conducts heat, thereby controlling the temperature in the cavity and accelerating the cooling and molding of the petals in the cavity.

[0011] The beneficial effects of this utility model are as follows: by placing materials into the cavity, the lower mold body and the upper mold body are squeezed to form a petal model. The cutting body and the upper mold body are automatically separated by the return spring. The cutting body moves toward the lower mold body and automatically cleans the burrs on the edge of the petal in cooperation with the cutting surface. The liquid delivered through the liquid infusion channel conducts heat, thereby controlling the temperature in the cavity and accelerating the cooling and forming of the petals in the cavity.

[0019] like Figures 1-4The present invention discloses a 3D printed rose petal mold with biomimetic texture, comprising a lower mold body 1 and an upper mold body 2, wherein cavities 3 are respectively provided on the lower mold body 1 and the upper mold body 2; a cut surface extending along the edge of the cavity 3 is provided on the lower mold body 1, and the cut surface is perpendicular to the side of the lower mold body 1 where the cavity 3 is provided; the edge of the upper mold body 2 is adapted to the edge of the cavity 3, and a cutting body 4 adapted to the cut surface is slidably provided on the upper mold body 2.

[0020] Liquid material is placed in the cavity 3 of the lower mold body 1. The upper mold body 2 moves toward the lower mold body 1. The lower mold body 1 and the upper mold body 2 squeeze the material and form a petal model. Some material overflows from the cavity 3 and forms burrs. The cutting body 4 moves toward the lower mold body 1 and cuts the burrs on the edge of the petal with the cutting surface. The petal model in the cavity 3 gradually cools down until the petal solidifies.

[0021] like Figure 1 and Figure 2 The lower mold body 1 shown is provided with a slide rod 5 parallel to the cutting surface, and the cutting body 4 is slidably mounted on the slide rod 5.

[0022] The cutting body 4 slides on the slide bar 5 and moves toward the lower mold body 1. The cutting body 4, in conjunction with the cutting surface, cuts the burrs on the edge of the petals.

[0023] like Figure 1 and Figure 2 The distance between the cutting body 4 and the lower mold body 1 is greater than the distance between the upper mold body 2 and the lower mold body 1, and the cutting body 4 and the upper mold body 2 are connected by a return spring 6; the cutting body 4 is connected to a pressing plate 10, and the pressing plate 10 is connected to the upper mold body 2 by a return spring 6; the axis of the return spring 6 is parallel to the axis of the cutting surface.

[0024] Liquid material is placed in the cavity 3 of the lower mold body 1. The cutting body 4 is pressed down, and the cutting body 4 slides on the slide bar 5 and drives the upper mold body 2 towards the lower mold body 1 through the return spring 6. The lower mold body 1 and the upper mold body 2 come into contact and squeeze the material. The material forms a petal model in the cavity 3. Some material overflows from the cavity 3 and forms burrs. The cutting body 4 is pressed down further, the return spring 6 contracts, the cutting body 4 moves towards the lower mold body 1 and cuts the burrs on the edge of the petal with the cutting surface. The petal model in the cavity 3 gradually cools down until the petal solidifies.

[0025] After the petals are formed, the cutting body 4 is pulled upwards, the return spring 6 relaxes, the cutting body 4 slides on the slide bar 5 and drives the upper mold body 2 to move upwards through the return spring 6 until the upper mold body 2 separates from the lower mold body 1 and the petal model is removed.

[0026] like Figure 1 and Figure 2 A support 7 is fixed on the upper mold body 2, and the distance between the support 7 and the lower mold body 1 is equal to the distance between the upper mold body 2 and the lower mold body 1.

[0027] The upper mold 2 drives the support 7 to move toward the lower mold 1. The support 7 and the lower mold 1 come into contact, and at the same time the upper mold 2 and the lower mold 1 come into contact. The upper mold 2 and the lower mold 1 complete the extrusion of the material, and the material forms a petal model in the cavity 3.

[0028] like Figure 1 and Figure 2 The lower mold body 1 shown has a positioning groove extending vertically toward the side of the lower mold body 1 where the cavity 3 is located, and the bracket 7 slides through the positioning groove.

[0029] The upper mold 2 drives the bracket 7 to move toward the lower mold 1, and the bracket 7 enters the positioning groove and slides in the positioning groove.

[0030] like Figure 1 and Figure 2 A cutting blade 8 extending along the edge of the cavity 3 is fixed on the cutting body 4 shown.

[0031] The cutting body 4 drives the cutting blade 8 to move towards the lower mold body 1, and the cutting blade 8, in conjunction with the cutting surface, cuts the burrs on the edge of the petals.

[0032] like Figure 1 and Figure 2 The lower mold body 1 and the upper mold body 2 are respectively provided with liquid infusion channels 9, and the liquid infusion channels 9 in the lower mold body 1 and the upper mold body 2 enclose the cavity 3; the lower mold body 1 and the upper mold body 2 are respectively provided with inlet and outlet that connect to the liquid infusion channels 9.

[0033] Coolant is introduced into the infusion channel 9, and the coolant exchanges heat with the petal model in the cavity 3, thus accelerating the cooling of the petal model.

[0034] In actual production, liquid material is placed in the cavity 3 of the lower mold body 1. The cutting body 4 is pressed down, and the cutting body 4 drives the cutting blade 8 to slide on the slide rod 5. At the same time, the cutting body 4 drives the upper mold body 2 to move towards the lower mold body 1 through the return spring 6. The upper mold body 2 drives the support 7 to move towards the lower mold body 1. The support 7 enters the positioning groove and slides in the positioning groove until the support 7 and the lower mold body 1 come into contact. At the same time, the upper mold body 2 and the lower mold body 1 come into contact. The upper mold body 2 and the lower mold body 1 complete the extrusion of the material. The material forms a petal model in the cavity 3. Some material overflows from the cavity 3 and forms burrs. The cutting body 4 is pressed down further, the return spring 6 contracts, and the cutting body 4 drives the cutting blade 8 to move towards the lower mold body 1. The cutting blade 8 cuts the burrs on the edge of the petal with the cutting surface. Coolant is introduced into the liquid infusion channel 9. The coolant and the petal model in the cavity 3 exchange heat, and the petal model in the cavity 3 cools down faster until the petal solidifies.

[0035] After the petals are formed, the cutting body 4 is pulled upwards, the return spring 6 relaxes, the cutting body 4 slides on the slide bar 5 and drives the upper mold body 2 to move upwards through the return spring 6 until the upper mold body 2 separates from the lower mold body 1 and the petal model is removed.
