Description

Ejecting line position mechanism

Technical Field

The utility model relates to the technical field of ejection mechanisms, in particular to an ejection slide mechanism.

Background

The plastic part is cooled and shaped in the mould, and because of volume shrinkage, a packing force is generated on the core, and when the core is ejected from the mould, the friction force generated by the packing force must be overcome. For the cylinder and shell plastic parts without through holes, the atmospheric pressure needs to be overcome when the plastic parts are demolded and pushed out. In injection molding, a mechanism for safely and nondestructively ejecting a cooled and solidified plastic product and a casting system (gate material) from a mold is called a mold release mechanism, which is also called an ejector mechanism or an ejector mechanism.

When the existing die line position bone position is deeper, the die stripping angle is generally increased or ejection is performed by a thimble, and in order to avoid damaging products, a line position mechanism is generally added in the die to reduce damage to the products;

as disclosed in chinese patent publication No. CN205097476U, an "ejection line mechanism" is disclosed, it adds a line position on a non-important appearance surface of a product, wraps a part of glue position, and when the line position is not separated from the product, the ejection mechanism ejects the whole line position mechanism with the product for a distance, so that the product is separated from a rear mold core, and then opens the line position, so that the product is separated from the line position mechanism, thereby achieving the purpose of demolding the product, and when the mechanism is used for demolding, a clamping line is not remained on the important appearance surface of the product, but in actual use, the ejector pin ejects, the surface of the product has shrinkage and ejection phenomenon, and the appearance of the product is affected.
