Problems solved by technology

[0003] In the existing mold design using software, the parts library cannot meet the needs of die-casting mold thimble design, and the existing functions cannot realize batch import of all thimble models into the design assembly, and cannot distinguish the particularity of part models in batches. Automatic model opening can be performed on the set die-casting mold thimble holes in batches

Embodiment Construction

[0017] 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, so as to define the protection scope of the present invention more clearly.

[0018] according to figure 1 , a semi-automatic design method for thimble holes in die-casting molds, including taking the thimble diameter extracted from the shape of the die-casting product as the design basis, and automatically batch-importing the extracted or created thimble diameter into the thimble basic model through a written software program , and it is possible to switch whether the thimble style and thimble sleeve are set or not. After the final setting is completed, the model will automatically open holes in batches on the target part model.

[0019] In this embodiment, CATIA software is used to carry out the semi-automatic operations of die-casting mold thimble setting, thimble mode...

Abstract

The invention discloses a semi-automatic design method for ejector pin holes in a die-casting die, which comprises the following steps of: by taking the ejector pin diameter extracted from the shape of a die-casting product or the ejector pin diameter created by a designer as a design basis, automatically importing the extracted or created ejector pin diameter into an ejector pin basic model in batches through a compiled software program; whether an ejector pin type and an ejector pin sleeve are set or not can be switched, and after final setting is completed, automatic batch model trepanning is conducted on the object part model. By means of the mode, according to the semi-automatic design method for the ejector pin hole in the die-casting die, on the basis of existing CATIA software, the design standard of the ejector pin of the die-casting die is written into a software program, and semi-automatic design of the ejector pin hole of the die-casting die can be accurately and efficiently completed in combination with the created ejector pin basic model.

Description

technical field [0001] The invention relates to the field of mold design, in particular to a semi-automatic design method for ejector pin holes in die-casting molds. Background technique [0002] There are two types of thimbles: round thimbles and flat thimbles. The specific requirements have to be determined according to the structural position of the product. During the die-casting process, when the mold cavity is filled with molten alloy and starts to demould, it is pushed out by the push plate of the rear mold. When the thimble reaches the preset position, the thimble pushes the product out to separate the product from the mold. [0003] In the existing mold design using software, the parts library cannot meet the needs of die-casting mold thimble design, and the existing functions cannot realize the batch import of all thimble models into the design assembly, and cannot batch distinguish the particularity of the part models. Automatic model opening can be performed on ...
