Problems solved by technology
[0004] In order to eliminate the burrs, there are many existing technologies, such as scraping off the burrs manually with a scraper. This method is very inefficient, and improper operation will damage the injection molded parts. However, there is no effective way to solve this problem in the industry. a question

Embodiment
[0029] Such as figure 1 As shown in -5, the present invention proposes a method for eliminating the ejector pin position burrs on the injection molding product from affecting the normal use of the product for a special injection molding product. Figure 1-2 As shown, due to its special shape, the injection molded product 10 has to be provided with a thimble position on the use surface 11 of the product (the so-called use surface means that the product needs to be in contact with other objects during use), because in this product Setting the thimble at other positions on the same side of the use surface 11 will damage the product, and setting the thimble on the other side of the use surface of the product is difficult to eject the product. After the thimble position 12 is set on the use surface 11 of the product, due to the gap between the thimble and the movable template, the thimble will produce burrs at the thimble position after the product 10 is ejected, and the raised thi...

The invention relates to a method and a mold for removing influences by burs on an ejector pin position. According to the method for removing the influences by the burs on the ejector pin position, the ejector pin position is placed on a plane or a concave face. The method for removing the influences by the burs on the ejector pin position is characterized by comprising the steps: a glue reducing position is arranged on an area where the ejector pin position located, the ejector pin position is in the range of the glue reducing position, the glue reducing position is located on the plane or the concave face as well and the area of the glue reducing position is smaller than the area of the plane or the concave face; and the depth of the glue reducing position arranged is larger than the height of the burs on the ejector pin position. According to the method and the mold for removing the influences by the burs on the ejector pin position, the glue reducing position is arranged in the ejector pin area, the burs on the ejector pin position is located in a concave pit of the glue reducing position, the depth of the concave pit is larger than the height of the burs and existence of the concave pit does not influence normal use of a product so that if the burs are located on an ejector pin, the normal use of the whole product is not influenced. The method and the mold for removing the influences by the burs on the ejector pin position have the advantages of being simple in structure and low in cost.
Description
【Technical field】 [0001] The invention belongs to the technical field of mold design and manufacture, and relates to a method and a mold for eliminating the influence of burrs at ejector pin positions of injection molding products. 【Background technique】 [0002] For some injection molded products, some planes are used surfaces, and these used surfaces require flat and smooth surfaces, which can facilitate other objects to slide on the planes. However, the shape of these injection molded products is very special, and the used surface has to be provided with ejector pins. , because the thimble position cannot be set in other places or is not suitable for setting the thimble position, such as figure 1 As shown, the use surface 11 of the injection molded product 10 has to be used to set the thimble position 12 . [0003] After the thimble ejects the product, it will leave burrs on the thimble position of the product, especially after the thimble is used for a long time, the fr...
