Abstract

The invention relates to a die mechanism capable of realizing product formation by kiss-off through angle lifters and extraction of the angle lifters from undercuts. The die mechanism comprises a fixed die and a moving die, wherein a fixed clamping plate (15), a support plate (265) and a fixed mold plate (185) are tightly connected by screws; guide sliding holes (195) are formed in the fixed mold plate (185); the fixed die angle lifters (65) are mounted in the guide sliding holes (195); the t positions of the fixed die angle lifters (65) are in contact with the m positions of a moving mold plate (165) so as to form penetration holes of the product b at f positions; the s positions of the fixed die angle lifters (65) are matched with the undercuts e in the product b; a limiting screw (215) is connected to the rear end of each of the fixed die angle lifters (65); the limiting screws (215) and springs (55) are mounted in and sleeved with the guide sliding holes (195); one end of each of the springs (55) is propped against a pressing plate (205), and the other ends of the springs are propped against the tail parts of the fixed die angle lifters (65).

Description

technical field [0001] The invention relates to a metal die-casting mold and a plastic injection mold, and is a mold mechanism for a slanted top to penetrate a product and a buckle position. Background technique [0002] Metal die-casting parts and plastic injection parts have an undercut mold mechanism on the side of the movable mold and the side of the fixed mold. The slider and the inclined slider are connected to the thimble. When the mold is opened, the thimble is driven by the thimble fixing plate and the thimble backing plate to eject the product. Due to the limitation, usually the depth of the undercut position can only be reduced, and then the undercut position on the side of the fixed mold can be directly removed by forced demoulding, so the product is prone to breakage, resulting in unqualified products. For some products with high size requirements, the depth of the undercut position cannot be reduced. The mechanism often used is to push the parts with the under...
