Abstract

The invention relates to a die mechanism capable of realizing core-pulling by adopting sliding blocks combined with angle lifters. The die mechanism comprises a fixed die and a moving die, wherein a fixed clamping plate (35), a fixed mold support plate (45), a first inclined pressure block (225) and a second inclined pressure block (65) are tightly connected by second screws (25); a moving mold plate (85), spacer blocks (145) and a moving clamping plate (155) are tightly connected by third screws (105); a first sliding block (235) and a second sliding block (55) are arranged above the moving mold plate (85); the first angle lifter (195), a first spring (205) and a first pull rod (225) are mounted in a first pull rod hole e of the first sliding block (235); the second angle lifter (165), a second spring (175) and a second pull rod (185) are mounted in a second pull rod hole q; the end surface W of the first angle lifter (195) and the end surface t of the second angle lifter (165) are in contact with the side surface K of a forming mold core (275) when the die is closed.

Description

technical field [0001] The invention relates to a plastic injection mold and a metal die-casting mold, which is a core-pulling mold mechanism combined with a slide block and an inclined top. Background technique [0002] After metal die-casting parts and plastic injection parts are molded, if there are upward and downward protrusions on the side of the product, and at the same time, there are upward or downward undercuts on the upper and lower protrusions, the existing technology is to reduce the depth of the upper and lower undercuts , and then the undercut is removed by forced demoulding. This structure is prone to breaking the upper and lower undercuts when the undercut is removed, resulting in the scrapping of the product. Effect. Another way is to design the parts at the upper and lower undercuts of the product and the molded product into a movable structure. When the mold is opened, the product and the movable parts are pushed out of the mold together, and then the pr...
