Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, refer to an orientation or positional relationship illustrated in the drawings for convenience in describing the present application and to simplify description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

A plastic mould for earphones is shown in figures 1 and 2 and comprises a bottom frame 1, a lower mould 2 and an upper mould 3, wherein the lower mould 2 is installed in the bottom frame 1, four corners of the bottom frame 1 are fixedly provided with guide corner posts 11, the four guide corner posts 11 are perpendicular to the bottom frame 1, the upper mould 3 and the lower mould 2 are connected to the inner sides of the four guide corner posts 11 in a sliding mode, linear bearings (not shown in the figure) are installed on the inner sides of the guide corner posts 11, the bottom frame 1 is provided with a plurality of guide posts 12, and the upper mould 3 is provided with through holes penetrating through the guide posts 12; the bottom frame 1 is provided with a positioning assembly for positioning the position of the lower die 2.
