BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 The figure is a workflow diagram of a semi-automatic design method for cooling holes in die-casting molds. DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] according to Figure 1A semi-automatic design method for cooling holes in die-casting molds includes using the die-casting mold results analyzed by external temperature analysis software as the basis for cooling design, and transmitting these design information to the software. Through the written software program, it automatically and batch imports according to the selected cooling basic model, automatically adjusts the cooling hole length in batches as needed, automatically batch models holes on the object part model, outputs cooling-related design information, combines the die-casting mold cooling design standards, and automates repetitive operations to ensure accurate and efficient die-casting mold cooling design.

[0023] The die casting mold cooling setting by CATIA software realizes the semi-automatic functions of cooling modeling, cooling adjustment, cooling hole creation and setting data export.

[0024] The specific steps include

[0025] 1) Establish a parts library: Establish a cooling basic model parts library in the software program and write the design standards. Each cooling basic model can realize the arbitrary switching function of different specifications and parameter sizes.

[0026] The cooling basic model parts library includes commonly used cooling basic models required for die-casting mold cooling design.

[0027] By creating the cooling basic model parts library, the commonly used cooling basic models are provided to mold designers, and the design operators do not need to create cooling models every time. In addition, the cooling models in the cooling basic model parts library can be added, deleted or changed according to needs.

[0028] 2) Automatic position import: Import the cooling basic model into the die-casting mold assembly at one time according to all the specified configuration points, and maintain the upper and lower layer link relationship. The upper and lower layer link relationship is that when the cooling hole diameter changes, the other parameters related to the cooling hole diameter will also change accordingly.

[0029] The cooling basic model includes cooling holes and cooling pipes.

[0030] The configuration points are determined by the temperature analysis software after analyzing the parts, and the diameter of the cooling hole is also determined.

[0031] The cooling style selected by the designer is batch-imported into the cooling basic model according to all specified configuration points, thereby realizing efficient semi-automatic import of cooling pipes and related parts, cooling holes, etc., which can ensure the consistency of the set cooling and improve the efficiency of the cooling design operation.

[0032] 3) Overall length adjustment: Automatically identify the shape of the die-casting mold product and automatically adjust the cooling hole length in batches according to the design standards.

[0033] The cooling hole lengths can be automatically adjusted in batches to account for differences in die casting mold product shapes, thus improving the efficiency of cooling design while eliminating manual work by designers.

[0034] 4) Individual length adjustment: performing local length adjustment on the cooling holes after batch adjustment in step 3).

[0035] Before adjusting the length individually in step 4), the temperature analysis software is required to perform analysis, and after analysis, step 4) is performed. The temperature analysis software is repeatedly performed on the cooling hole adjusted in step 4) until the simulation temperature of the die-cast product reaches the specified temperature, and then step 5) is performed.

[0036] 5) Automatic hole opening: The cooling holes adjusted in step 4) are opened in batches on the target part model, and the hole opening operation is completed quickly and accurately with one click.

[0037] All the cooling holes that have been set are automatically opened on one or more object part models, thus achieving automatic operation while ensuring accuracy.

[0038] 6) Data output: The set cooling hole related information is output in the form of a table, which can not only be used to confirm the set content, but also can be used as a part of the drawing to reduce the time of drawing production.

[0039] Output the key cooling design information such as the position, diameter and length of all cooling pipes and cooling holes to the specified table, and compare the data. The output table information can not only serve as the basis for the designer's confirmation and adjustment, but the final data can also be used as part of the drawing.

[0040] Compared with the prior art, the present invention provides a semi-automatic design method for cooling holes in a die-casting mold. Based on the existing CATIA software, the design method writes the cooling design standards of the die-casting mold into the software program, and combines the created cooling basic model to accurately and efficiently complete the semi-automatic design of the cooling holes of the die-casting mold.

[0041] This method writes the cooling design standards of the die-casting mold into the program. Regardless of the designer's ability, the stability of the design quality can be guaranteed, and a basic cooling model can be created to meet the designer's needs for the cooling model. There is no need to make additional models every time a design is made. By utilizing the additional writing functions of the program, especially the repetitive parts, the setting operation can be completed by executing the program with one click, ensuring the efficiency of the cooling setting.
