The mold core extends into the upper mold cavity and cooperates with the upper mold cavity to form a molding cavity for the product, constituting the overall external size and shape of the product, and cooperates with the rib molding groove to constitute the ribs and rib height at the mouth of the product, and a through hole is provided below the mold core; the female mold is arranged below the middle plate, and a lower membrane cavity cooperating with the middle plate is provided above the female mold, the lower membrane cavity is in direct contact with the middle plate, and the middle plate is clamped and locked between the female mold and the male mold.

[0006] Furthermore, in the above-mentioned high-efficiency molding mold for an earphone shell, the male mold and the female mold are of the same size.

[0007] Furthermore, in the above-mentioned earphone shell high-efficiency molding mold, the length of the middle plate is longer than the male mold and the female mold, and the width is smaller than the male mold and the female mold. After the middle plate is assembled, it is embedded in the male mold and the female mold to ensure the stability of the mold during the molding process and improve the product quality.

[0008] Furthermore, in the above-mentioned high-efficiency molding mold for earphone shells, protrusions are provided on both sides of the mold core, and the mold core cooperates with the upper mold cavity and is ejected by the protrusions to form small ears and C-angles of the product.

[0009] Furthermore, in the above-mentioned high-efficiency forming mold for earphone shell, the size of the lower membrane cavity is consistent with the middle plate, and after the middle plate is installed in the lower membrane cavity, the upper end plate surface is flush.

[0010] Furthermore, the above-mentioned earphone shell high-efficiency molding die has at least two molding cavities, so that multiple products can be molded at one time, thereby improving production efficiency.

[0011] Furthermore, in the above-mentioned high-efficiency molding mold for earphone shells, the lower membrane cavity is connected to the through hole. After the middle plate and the mother mold are separated, the inner hole waste of the product can be directly processed from the through hole, thereby improving production efficiency.

[0012] It can be seen from the above technical scheme that the utility model has the following beneficial effects: the utility model described in the utility model is an efficient molding mold for earphone shells, which is simple in structure and easy to use. It adopts a three-layer structural design of a male mold, a middle plate, and a female mold to ensure the stability of the mold during hot pressing, thereby improving product quality. The length of the middle plate is greater than that of the male mold and the female mold, which facilitates demolding after product molding. The mold core on the middle plate is connected to the through hole of the lower membrane cavity. After the middle plate and the female mold are separated, the waste material in the inner hole of the product can be directly processed from the through hole, and multiple molding cavities can be set. Multiple products can be produced by hot pressing at one time, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
