Problems solved by technology

[0003] This kind of undercut solution needs to add two boards inside the template, namely the upper ejector board and the lower ejector board, so the corresponding formwork needs to be enlarged, which wastes materials and resources

Abstract

The invention discloses an injection mold. The injection mold comprises a stripper plate, a female mold plate, a female mold core, a male mold core, an oblique lifter, an elastic mechanism and a limiting mechanism, wherein the female mold plate is arranged below the stripper plate; the female mold core is arranged below the female mold plate, the male mold core is arranged below the female mold core, and a mold cavity for a product to be subjected to injection molding is formed between the female mold core and the male mold core; the upper end of the oblique lifter is fixed on the stripper plate, the oblique lifter downward penetrates through the female mold plate and the female mold core obliquely, and the lower end of the oblique lifter is matched with a barb position of a female mold; the elastic mechanism is used for upward applying an elastic force to the oblique lifter in the oblique direction, and the limiting mechanism is used for limiting the movement of the oblique lifter in the oblique direction. The injection mold has the characteristics that the mounting is convenient, the processing is simple, the female mold barbing manner is ingenious, the required space is small, and the waste is reduced.

Description

technical field [0001] The invention relates to an injection mold. Background technique [0002] When designing an injection mold, if the female mold has undercuts, it is also the same as the male mold with undercuts. Two ejector plates are required to cooperate with the inclined top to remove the undercuts. The principle of this structure is: when the male and female molds are opened, the needle plate of the female mold starts to move downward due to the Uril glue, and at the same time, the inner inclined top of the female mold also moves accordingly until it breaks away from the barb. The guide post that runs through the upper mold base, stripper plate, upper ejector plate, lower ejector plate and mother template, the guide post is responsible for guiding the needle plate to prevent the inclined top from being misaligned and the card from being broken. [0003] This kind of undercut solution needs to add two boards inside the template, namely the upper ejector board and t...
