To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.
A first embodiment of the present disclosure provides a manufacturing method of a casting mold, the flow of which is shown in fig. 1, including steps S101 to S104:
s101, designing three-dimensional model data and wall thickness of a blank mold, designing the blank mold to perform shell extraction treatment, and filling the interior of the designed blank mold by adopting a preset lattice structure to generate a printing model of the blank mold, wherein the wall thickness of the blank mold is the first thickness.
In specific implementation, the predetermined lattice structure in the blank mold can play a role in supporting the blank mold. The predetermined lattice structure may be a diamond lattice structure, a honeycomb lattice structure, etc., and the predetermined lattice structure occupies 30% to 50% of the filling space.
The first thickness is generally not less than 11mm, and the size is about 10mm relative to the thickness of the finished casting mold to be obtained, which is not less than 1mm as a margin for the later reworking, and the second thickness is not less than 1 mm.
S102, printing a blank mould through a 3D printer and a printing model, wherein the blank mould is made of a preset high polymer material.
And S103, transferring the blank mould to a processing platform of a five-axis numerical control processing machine tool, and calibrating and fixing the coordinates of the blank mould.
The process can be realized by combining a 3D printer and a five-axis numerical control machining tool to form an assembly line, namely, after a finished product is machined from the 3D printer, a blank die is directly transferred to the five-axis numerical control machining tool through equipment such as a mechanical arm or a conveyor belt. After the blank die is transferred to a five-axis numerical control machining machine tool, the coordinate calibration and fixation can be carried out on the blank die, so that the subsequent precise fine machining can be conveniently carried out.
And S104, processing the outer side of the blank die according to a second thickness through a five-axis numerical control processing machine tool to obtain a casting die, wherein the first thickness is larger than the second thickness.
Because the blank mould for 3D printing has a certain additional increment thickness in order to increase the accuracy and the adaptable range of the mould, the blank mould needs to be reprocessed once in the process to obtain a final finished product, and the process is to thin the thickness of the outer wall of the blank mould so as to ensure that the whole blank mould conforms to the finishing process of the size of a casting mould.
This disclosed embodiment will have the process that needs the wood mould of manual work to realize by the 3D printer now, the 3D printer uses macromolecular material to print, in case the printing model that has input needs the printing mould, just can print, the blank mould after will printing again places five numerical control machine tools and processes, save time for the mode of current wood mould of manual work, higher printing rate of accuracy has, weight is lighter for wood model, and is not perishable, the service life is more of a specified duration.
In the implementation process, whether the blank mould is split and printed or not can be determined through the 3D printer, for example, when the size of the blank mould exceeds the maximum size which can be printed by the 3D printer, the blank mould is determined to be split and printed, and the three-dimensional size data of the blank mould can be automatically split through the 3D printer so as to obtain the blank mould to be printed of each part.
If the split printing is carried out, each part of blank die is respectively printed according to the three-dimensional size data and other preset parameters of a plurality of part of blank dies to be printed, and glue is coated on the connecting surface of each part of blank die for splicing under the condition that all the part of blank dies finish printing, so that the complete blank die is obtained.
The embodiment of the disclosure can print no matter how large the casting mold is, and has a wider casting range.
The predetermined polymer material may be Polylactide (PLA), acrylonitrile-butadiene-styrene copolymer (ABS), resin composite material, glass fiber reinforced plastic, polyamide PA, PA composite material, or the like.
In the concrete implementation, PLA, ABS or resin composite material, glass fiber reinforced plastic, polyamide PA and PA composite material and the like are used as raw materials to carry out 3D printing manufacturing on a mould, high polymer material is melted and extruded at high temperature (170 ℃ to 190 ℃) to form a blank mould shape, and if the mould is large in size, block design printing can be carried out, and then splicing is carried out; transferring the printed mold blank to a platform of a five-axis numerical control machining machine tool, leveling the bottom surface, straightening one side of the blank, and finally determining a reference coordinate; and finally, removing the allowance of the die blank which is not less than 1mm by using a five-axis numerical control machining tool, and finely machining to the size of a die finished product to obtain the casting die.
The mould that 3D printer printed and obtain replaces traditional wooden mould, through carrying out the dot matrix design, optimizing 3D to the mould model and printing the parameter, prefers green pollution-free and polymer material of good performance, has realized that 3m and following full-scale casting model is integrative to be printed, has excavated 3D and has printed the mould and replace wooden mould's huge potentiality. Through constantly verifying the discovery, traditional wooden mould is compared to 3D printing die, and the precision is higher, and the life-span is more than several times of traditional wooden mould, and material weight only is 1/3 of traditional wooden mould, makes 3 times to 4 times fast, and the model quality does not receive the temperature influence.
The embodiment of the disclosure also provides a casting mold, which is manufactured by adopting the manufacturing method of the casting mold provided in the embodiment. After the casting mold is manufactured, the casting mold can be used in cooperation with sand, the shape of the device to be cast (i.e., the shape of the casting mold) can be obtained in the sand, and the device can be cast.
