Embodiment Construction

[0052] The following is attached Figure 1-21 The application is described in further detail.

[0053] The embodiment of the present application discloses a straight shell, referring to figure 1 and figure 2 , the workpiece includes a body part 1 and a two-color layer 2. The body part 1 is arranged in a straight cylindrical shape. The interior of the body part 1 is hollow and has openings at both ends. The body part 1 can be injection molded with a hard ABS material. The body part 1 is used for For electronic components to install. In addition, the two-color layer 2 is sleeved on the body part 1, and the outer surface of the body part 1 is recessed to be provided with an accommodating groove 101 for the two-color layer 2. Under the action of the accommodating groove 101, the surface of the two-color layer 2 and the The surface of the body part 1 is flush, wherein the body part 1 and the two-color layer 2 are integrally connected to each other, and when the two-color layer ...

Abstract

The invention relates to the field of injection molding, in particular to a straight cylinder shell and a double-color injection mold thereof. The main points of the technical scheme are that a workpiece comprises a body part and a double-color layer; the double-color layer is arranged on the body part in a sleeving mode, the body part and the double-color layer are integrally connected, and a plurality of first connecting grooves are formed in the end face of the body part in the circumferential direction of the body part; a plurality of first connecting bosses correspondingly embedded in thefirst connecting grooves are arranged on the inner wall of the double-color layer, second connecting grooves are formed in the outer circumferential face of the body part, and second connecting bosses embedded in the second connecting grooves are arranged on the inner wall of the double-color layer. The shell has a stable connection effect. The invention also discloses a direct injection mold. The injection molding of the workpiece is achieved in a double-color injection molding mode, the production efficiency of the workpiece is improved, and the diversity requirements of products are met.

Description

technical field [0001] The present application relates to the field of injection molding, in particular to a straight shell and a two-color injection mold thereof. Background technique [0002] Since the advent of plastic parts, they have been widely used in daily life due to their good processing characteristics, light weight and chemical stability. Among them, different plastic materials can be selected according to actual needs in different injection mold types. Molding is carried out in the cavity to obtain plastic parts with different shapes and textures to meet the diverse needs of different plastic products. [0003] At present, there is a straight cylindrical workpiece, which includes a straight body part, and a cavity is formed inside the body part for accommodating and installing electronic components. This type of workpiece can be used for portable cameras and lamps, etc. Electronic products are installed. In order to improve the user experience of the product, i...
