Abstract

The invention provides an injection mold capable of realizing local delayed ejection, and is used for solving the problem that in the prior art, ejection block marks are generated when the mold is used for forming. The injection mold capable of realizing the local delayed ejection comprises a movable mold, a fixed mold, a first straight ejector rod and a first straight ejector block, wherein a forming inner cavity is formed between the movable mold and the fixed mold, the movable mold comprises a driving plate, the first straight ejector rod is arranged in the movable mold, the driving plate can push the first straight ejector rod in the mold closing direction, the first straight ejector block is installed at the end, close to the forming inner cavity, of the first straight ejector rod, afirst elastic piece is arranged at the end, away from the forming inner cavity, of the first straight ejector rod, the first elastic piece is installed at the end, away from the forming inner cavity,of the first straight ejector rod, the first elastic piece is used for tensioning the first straight ejector rod in the movable mold side direction, and in an initial state of the driving plate, a first initial interval is formed between the first straight ejector rod and the driving plate. The injection mold capable of realizing the local delayed ejection can avoid generation of the ejection block marks.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an injection mold with partially delayed ejection. Background technique [0002] At present, people have higher and higher requirements for the quality of cars, especially car interior parts, such as the front defrosting panel of the instrument panel, door panel decorations, back door decoration panels, side panels of the central control box, etc. The back of these parts is composed of many ribs. Strengthening, it is very easy to produce serious top block printing in some areas of the product appearance, even if the product appearance is textured, it cannot be covered up. [0003] Usually, during the injection molding process of these parts, when there are serious jacking marks in some parts of the product appearance, it is necessary to check whether the jacking block and the moving mold are matched smoothly, etc., and if it still cannot be solved, it is adjusted by adjusting the p...
