Description
Technical Field
The invention relates to the field of molds, in particular to a method for engraving Song style characters on a mold molding surface.
Background
The injection molded product is engraved with various characters, which serve as marks for identifying the material of the product, the code of the product, the name of the product, the commodity flow number of the product, the left and right marks of the product, and the like. In the process of designing and manufacturing the mold of the injection molding part, permanent characters are generated on the molding surface of the mold, which is an important link in the process of designing and manufacturing the injection mold. The font of the mold molding surface firstly meets the functional requirements of product design, namely the accuracy of the content of the font and the accuracy of the position of the font; the second is appearance decoration, which requires the appearance of the font to be beautiful to improve the competitiveness of the product. At present, most of conventional fonts are black-body characters and Song-body characters, wherein the black-body characters are more in most cases because of simple processing, single stroke and uniform thickness; on the contrary, the stroke of the Song style character is divided into thick and thin strokes, the processing is complex, the difficulty is high, but the appearance is more beautiful, so the Song style character is selected on many products at present, particularly, the Song style character is specified on some national standards, such as a national 3C mandatory certification mark, and the specified font is the Song style character. However, engraving song's body characters on a mold form has not been a good solution, limited to the current practical level of processing and the characteristics of the processing machine. In the previous stage of product design, designers generally avoid designing such fonts in consideration of actual manufacturing techniques, and the commonly used fonts are still in bold type, but when encountering marks such as 3C, the sons character must be selected. At present, two methods, namely an electro-erosion machining technology and an EDM (electrical discharge machining) method, are generally adopted, but characters processed by the method are rough, the size and the precision of the characters cannot be controlled, particularly the positions of the characters cannot be determined, and the use performance of injection products is sometimes influenced due to excessive human factors. Although the prior mirror surface electro-corrosion processing technology exists, the processing time is too long, the cost is too high, and the investment of a machine tool in the early stage is also large, so that the problem of how to carve the Song style characters on an injection mold is an urgent need to be solved by mold manufacturing enterprises, and the extensive application and manufacturing of the Song style characters on mold products can be realized by breaking through the problem so as to improve the added value and the competitiveness of the products.
Disclosure of Invention
The invention aims to provide a method for engraving Song style characters on a molding surface of an injection mold, which realizes the engraving of complicated Song style characters.
The method for engraving the Song style characters on the molding surface of the injection mold comprises the following steps:
1) the design of the Song style words on the product,
the font is selected to be parallel to the product demoulding direction, so that the designed font is smooth and smooth, the font is designed on the surface of a gentle product, convenience is provided for the subsequent process, and when an irregular product or a complex product curved surface is encountered, a wider area is selected to design the font, so that a better algorithm is provided for programming;
2) designing the Song style characters of the mold, namely designing the mold according to the data of the product when the data of the product is obtained, simultaneously, necessarily keeping the association relationship between the characters and the product, and leading the association relationship into programming software together with the parameter relationship for programming when the mold design is finished;
3) the determination of the processing strategy of the Song style word,
determining font processing range and processing technology, setting basic processing parameters according to the purpose and requirement of processing, defining direction for generating tool path,
for the processing of characters on the molding surface of the die, the processing range is divided firstly. Considering that the characters of the Song font are different in size and width, the single line processing mode of the SRFPRF is difficult to use during processing, and the mode is only used for processing the black font, so the finish processing is generally carried out by adopting the feed mode of the SRFPKT. The processing is carried out in two steps: firstly, determining the size of a font, reasonably selecting a programmed cutter, and generally selecting a flat bed knife with a taper compared with the Song font with different widths, so that the side wall of the processed font has a better demoulding angle; when the bottom surface of the Song body character is finely processed, the allowance is generally cut off by adopting an annular processing mode of SRFPKT, and the SRFPKT needs to spread outwards from the center during processing, so that the last knife can be trimmed once;
for the processing of characters on the molding surface of the die, the processing range is divided firstly. Considering different sizes and widths of the characters of the Song style characters, finish machining is carried out in a feed mode of SRFPKT, and the characters are divided into two steps during machining: firstly, determining the size of a font, selecting a programming cutter, and selecting a flat bed knife with conicity compared with the Song font with different width and fineness; when the bottom surface of the Song body character is finely processed, the allowance is cut off by adopting an annular processing mode of SRFPKT, and the SRFPKT needs to spread outwards from the center during processing, so that the last knife can be trimmed once;
the key element of the carving technology of the Song body characters on the molding surface of the mold is to ensure the smoothness, smoothness and smoothness of the side wall and the bottom surface of the characters, and the cumulative processing mode is adopted, namely, when the SRFPKT is used for carrying out fine processing in a feed mode, only 0.02MM of cutting amount is processed each time, so as to ensure that the cutting amount of the last layer is the minimum and play the most key role of light collection;
when a lettering program is calculated, the processing range is contracted, namely, a small virtual boundary line is used for calculating a font program, the triangular relation between the taper included angle and the depth of a cutter needs to be calculated during calculation, and the final processing program for lettering on the molding surface of the mold can be obtained;
4) generation of engraving tool path
After a program is checked and software simulation is carried out, tool paths are optimized, processing parameters are adjusted, marks are set for the positions of feed, retreat, processing and idle feed respectively, and an engraving and processing file is obtained according to an engraving and processing principle and a corresponding algorithm;
5) and post-processing, namely after the program is simulated and the safety is confirmed, selecting different post-processing files according to different machine tools to generate a G code program which can be directly read by the corresponding machine tool, directly reading and running the G code program by the machine tool, and directly generating the engraving G code through the post-processing of the cutter location file.
The invention reasonably selects the processing cutter to process in a layered accumulation way by setting the most proper processing range for the relatively complicated Song style characters, thereby obtaining the most real processing program. The processing method effectively executes the design intention, accurately reflects the position of the character on the product, and reasonably avoids the phenomena of over-cutting, cutter breaking and cutter jumping of the lettering cutter in the processing process. Because the program is simpler and the calculation amount of post-processing is not too large, the storage space occupied by the program is relatively small. During actual processing, the data transmission speed is smooth, and the phenomena of pause and nesting of data transmission do not exist, so that the strokes of the processed Song style characters are uniform, the edges of the processed Song style characters are neat, the bottoms of the characters are smooth and smooth, and the positions of the characters meet the design requirements.
Detailed Description
Hereinafter, a detailed description will be given of embodiments of the present invention. While the invention will be described and illustrated in connection with certain specific embodiments thereof, it should be understood that the invention is not limited to those embodiments. Rather, modifications and equivalents of the invention are intended to be included within the scope of the claims.
The method for engraving the Song body characters on the molding surface of the injection mold comprises the following steps:
1. designing the Song style words on the product:
in the product design process, the position of characters on the product is reasonably determined according to the requirements of product customers and the mandatory requirements of national regulations, the fonts are reasonably determined, some fonts which are difficult to realize are avoided, and some fonts of simple lines are selected more. When the style of the song body is related, the size and the position of the style are important to be considered. In the spatial position relation of the product surface, the direction of the font is determined to be perpendicular to the normal direction of the product surface or parallel to the demolding direction, and certainly, for the convenience of processing and the actual production of the product, the font is determined to be selected to be parallel to the demolding direction of the product, so that the designed font is smooth and smooth.
In the process, the important concern is that the fonts are designed on the surface of a gentle product, so that convenience is provided for the subsequent process. If the product is in an irregular product or a complex product curve, the later processing is more convenient to design, and a wider area design font is reasonably selected under the condition of not influencing the functions of the product, so that a better algorithm is provided for programming. This is also a convenient further factor that may be considered in programming.
2. Designing a mold Song style character:
when product data is obtained, the design of the mold is carried out according to the product data, meanwhile, the association relationship between the font and the product must be preserved, and in the design process of using Unigraphics, the Unigraphics has a proper noun, namely a 'parameter relationship'. As long as the parameter relationship is not deleted in the design process, the mold can be designed arbitrarily without affecting the shape and inherent properties of the font. At the end of the mold design, the parameter relationship is imported into the programming software for programming.
In designing the mold, the character of the character on the molding surface of the mold is important to be considered, so that the flow of plastic during injection molding and the demolding problem of the mold after molding are considered. The demolding angle of the side wall needs to be large enough, and the round corner transition between the side wall and the bottom surface needs to be considered, and the round corner is convenient to be processed together when the characters are engraved. In other words, the processing convenience and the actual requirement are combined in the process, and the processing convenience and the actual requirement are considered simultaneously.
3. Determining the processing strategy of the Song style word:
determining the font processing range and the processing technology, and setting basic processing parameters according to the processing purpose and requirements to generate a specified direction for the tool path.
For the processing of characters on the molding surface of the die, the processing range is divided firstly. Considering that the characters of the Song font are different in size and width, the single line processing mode of the SRFPRF is difficult to use during processing, and the mode is only used for processing the black font, so the finish processing is generally carried out by adopting the feed mode of the SRFPKT. The processing is carried out in two steps: firstly, determining the size of a font, reasonably selecting a programmed cutter, and generally selecting a flat bed knife with a taper compared with the Song font with different widths, so that the side wall of the processed font has a better demoulding angle; when the bottom surface of the Song body character is finely processed, the annular processing mode of SRFPKT is generally adopted to cut off allowance, and the allowance needs to be spread outwards from the center during processing, so that the last knife can be trimmed once.
The key element of the carving technology of the Song style characters on the molding surface of the mold is to ensure the smoothness, smoothness and smoothness of the side wall and the bottom surface of the characters. Typically, an accumulation process is used. That is, when the SRFPKT is used for fine machining, only 0.02MM of cutting amount is machined each time, and if the depth of the font is 0.2MM, ten programs need to be accumulated to ensure that the cutting amount of the last layer is the minimum and the most critical light-receiving function is achieved.
When the lettering program is calculated, the processing range should be properly contracted, namely, a small virtual boundary line is used for calculating the lettering program, the triangular relation between the taper included angle and the depth of the cutter needs to be calculated during calculation, the final processing program for lettering on the molding surface of the mold can be obtained, and the calculated program can be more in line with the design intention of the lettering after actual processing. After the program is calculated, the connection adjustment of the program needs to be properly carried out, so that the cutter lifting, cutter idling, cutter feeding and cutter withdrawing of the program are all within the safe value range.
4. And (3) generating a carving tool path:
after carefully checking the program and simulating the software, the path of the cutter can be optimized, the processing parameters are adjusted, marks are respectively set for the positions of feed, retreat, processing and idle feed, and an engraving processing file is obtained according to an engraving processing principle and a corresponding algorithm.
5. And post-processing, namely after the program is simulated and the safety is confirmed, selecting different post-processing files according to different machine tools to generate a G code program which can be directly read by the corresponding machine tool, directly reading and running the G code program by the machine tool, and directly generating the engraving G code through the post-processing of the cutter location file.
