Detailed Description
The following description of the embodiments of the present utility model will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.
As shown in fig. 1, the photo-curing 3D printing forming table of the present utility model includes a base 1, a flexible layer 2 and a metal sheet layer 3 arranged from bottom to top. And the printed product 4 is located on the upper surface of the sheet metal layer 3.
The base 1 is a metal block. The material of the flexible layer 2 may be one of PC, PP, PVC, PE, TPE, PTFE, PEEK, PVA, PET, PI, PEN, ABS. The flexible layer 2 is detachably connected with the base 1.
As shown in fig. 7, the upper surface of the base 1 is provided with five caulking grooves 11 (the number is not limited), and the width of the bottom of the caulking groove 11 is increased. The flexible layer 2 is matched with the base 1 and can be in knob type locking, plug type locking, elastic locking and the like. As shown in fig. 8 and 9, five clamping strips 23 are arranged on the lower surface of the flexible layer 2, and the number and the shape of the clamping strips 23 correspond to those of the caulking grooves 11. The clip 23 is inserted into the caulking groove 11 in the horizontal direction so that the flexible layer 2 is combined with the base 1. Moving the flexible layer 2 in the direction of the clamping bar 23 removes the flexible layer 2 from the base 1.
The flexible layer 2 may be reusable or disposable. As shown in fig. 8, the upper surface of the flexible layer 2 is designed with a through groove 21 penetrating longitudinally and transversely, the through groove 21 penetrates through two opposite side edges of the flexible layer 2, namely the whole width or length of the flexible layer 2, and in the application situation of fig. 11, the arrangement can reduce the adsorption force when the forming table is lifted, and the flexible layer 2 is also convenient to bend and twist. As shown in fig. 3 and 4, the depth of the through groove 21 is smaller than the thickness of the flexible layer 2.
As shown in fig. 8, a plurality of through grooves 21 penetrating longitudinally and transversely divide the area of the upper surface of the flexible layer 2 into a plurality of square areas, and each square area is provided with a metal sheet 31 as shown in fig. 1. All the metal sheets 31 constitute the metal sheet layer 3. The metal sheet 31 avoids the through grooves 21 described above, thereby facilitating the bending of the flexible layer 2.
As in fig. 1, the product 4 is in direct contact with the metal sheet 31.
As shown in fig. 2, the middle area of the upper surface of the metal sheet 31 is provided with nine slots 311 (the number is not limited). The slot 311 extends downward from the upper surface of the metal sheet 31, through the entire thickness of the metal sheet 31. In other embodiments, the slot 311 may not extend through the entire thickness of the metal sheet 31. Especially in the application case of fig. 11, the printed product 4 is under the forming table, the printed product is easy to fall under the gravity action of the printed product 4, and the slot 311 can enhance the adhesion between the printed product 4 and the metal sheet 31, so as to avoid the printed product 4 falling.
In this example, the horizontal cross section of the slot 311 is square, but may be circular or other shapes. The shape, size, depth and number of slots 311 may be designed according to the product size. During printing, the paste will remain partially within the slots 311 due to the viscous nature of the paste. When the first layer of the product is printed, the slurry in the slotted holes 311 of the metal sheet layer 3 and the first layer of the product are solidified and adhered together through ultraviolet light transmission, so that the effect of connecting the products is achieved. The first layer illumination power can be set with lower parameters, so that the problem of over-curing of first layer printing can be avoided.
The metal sheet 31 may be made of a metal material such as titanium alloy, stainless steel, aluminum alloy, or the like, and may also be bendable.
The metal sheet 31 and the flexible layer 2 may be connected by means of inlays, rivets, threads, glue or the like. In this example, the lower surface of the metal sheet 31 is provided with four connection posts 312 as shown in fig. 10, and the upper surface of the flexible layer 2 is provided with insertion holes 24 corresponding to the connection posts 312 as shown in fig. 6, and the connection posts 312 are inserted into the insertion holes 24 and are tightly fitted, so that the metal sheet 31 is fixed to the flexible layer 2. The receptacles 24 may or may not extend through the flexible layer 2.
As shown in fig. 5 and 6, the upper surface of the flexible layer 2 is further provided with bottom grooves 22, the number and positions of the bottom grooves 22 correspond to the slots 311 in the metal sheet 31, and the bottom grooves 22 communicate with the slots 311. The bottom groove 22 may deepen the depth of the cured resin. The cured resin extends from within the slot 311 into the bottom slot 22. The bottom slot 22 may or may not extend through the entire thickness of the flexible layer 2.
After printing, the flexible layer 2 can be directly taken down, and the new flexible layer 2 can be replaced for printing continuously. The position of the metal sheet layer 3 with the slotted holes 311 is strongly connected with the product 4, and the position without the slotted holes 311 is weakly connected. The flexible layer 2 is bent and twisted to separate the sheet metal layer 3 from the edges of the product 4 and the product 4 is removed from the sheet metal layer 3.
The contact surface of the product 4 using the forming table of the embodiment can be designed to be planar, no support is needed, and the printed blank has no burrs, so that a better planar effect can be obtained.
The above embodiments are only for illustrating the technical concept and features of the present utility model, and are intended to enable those skilled in the art to understand the present utility model and to implement the same, but are not intended to limit the scope of the present utility model, and all equivalent changes or modifications made according to the spirit of the present utility model should be included in the scope of the present utility model.
