Problems solved by technology

However, when designing products to be subjected to two-color injection molding, the selection of product materials is greatly restricted
When the designed product is limited by its appearance and identification requirements, and the material selected for its high temperature resistance and temperature difference does not meet the above selection criteria, based on the use of traditional mold structures for two-color injection molding, there will be a flushing phenomenon that will affect the quality of the product. Considering that this product cannot be made by the two-color molding method

Embodiment Construction

[0027] The two-color molding method of the present invention and the molded parts made by the two-color molding method can be applied to various types of product devices, such as portable electronic devices such as mobile phones, game machines, and personal digital assistants (PDA). device.

[0028] see figure 2 and Figure 4 As shown, the molded part 10 includes a first injection part 12 and a second injection part 15, and the first injection part 12 and the second injection part 15 are embedded in one body through the injection molding method.

[0029] Please also refer to image 3 and Figure 5 , the first shooting part 12 includes a main body 122 , a through slot 125 and a mounting portion 127 . The main body 122 is a substantially rectangular flat plate, which includes an upper surface 121 and a lower surface 123 opposite to the upper surface 121 . The through groove 125 is substantially rectangular, and is formed by opening substantially from the center of the uppe...

Abstract

The invention relates to a molding element and a double-color molding method of the molding element. The molding element comprises a first injection part and a second injection part. The first injection part and the second injection part are inserted in a body through the injection molding technology. The first injection part comprises a main body and a through-groove passing through the main body. The second injection part comprises a body and an embedding part. The embedding part is convexly arranged on one surface of the body and inserted in the through-groove of the first injection part, and a concave groove surrounding the embedding part is formed. The invention also provides the double-color molding method of the molding element.

Description

technical field [0001] The invention relates to a molded part and an injection molding method for making the molded part, in particular to a molded part and a two-color molding method for making the molded part. Background technique [0002] Generally, when performing two-color injection molding, it is necessary to consider how to select the material for the first injection molding (hereinafter referred to as the first shot material) and the second injection molding material (hereinafter referred to as the second shot material) to be subjected to two-color molding. Usually the high temperature resistance performance parameter of the first shot material selected should be higher than the high temperature resistance performance parameter of the second shot material. This is mainly to prevent the high temperature resistance of the material used for the second injection molding when the second injection molding is performed or is relatively close to the high temperature resistan...
