Full face barb exit structure

Abstract

The full-surface barb withdrawal structure of the present invention includes: the outer slider insert, which is arranged on the exterior surface of the outer molded product of the product; the outer slider body, which is connected with the outer slider insert; the first inclined guide post, which is arranged on the outer In the slider body, move the outer slider body to move; the inner slider insert is set on the inner side of the product to form the barb on the inner side of the product; the second inclined guide post is set in the inner slider insert to move the inner slider into Sub movement; oblique pin, the tail end is set in the male template to connect with the thimble of the mold, and one side of the head end of the oblique pin is formed into the product; the limiter is set in the male mold core at one end, and the other end is set in the inner slider In the insert, the end provided in the insert of the inner slider is provided with a vertical side; the insert pin, one end of the insert pin is in contact with the vertical side of the limiting insert. The full-surface barb exit structure of the present invention can withdraw the entire surface barb of the product by setting the oblique pin and the inlaid needle, which can not only ensure that the oblique pin ejects the product, but also prevent the product from sticking when the inner slider is inserted and the oblique pin is withdrawn. .

Description

【Technical field】 [0001] The invention relates to a mold structure, in particular to a whole-surface barb exit structure. 【Background technique】 [0002] In the production of plastic products, if there are a large number of limiting protrusions (RIB) on the inner side of the product, the entire surface of the inner side of the product will be undercut, and the entire surface of the undercut will be difficult to exit. [0003] see figure 1 and figure 2 shown, where figure 1 A schematic diagram of a product is shown, figure 2 illustrated figure 1 A partial enlarged schematic diagram of . The inner side of the product 10 has a plurality of protruding pillars, which leads to the phenomenon of undercuts 11 on the entire surface. The product 10 cannot be formed with a diagonal pin, and only the inner slider is used, which will cause the product 10 to be unable to be ejected, and the inner slider will easily stick to the product 10 when it is withdrawn, affecting the appear...

AI Technical Summary

Problems solved by technology

There are multiple protrusions on the inner side of the product 10, resulting in the phenomenon of undercuts 11 on the entire surface

The product 10 cannot be molded with oblique pins, only the inner slider is used for molding, which will cause the product 10 to be unable to be ejected, and the inner slider will easily stick to the product 10 when it is withdrawn, which will affect the appearance of the product 10
