Abstract

The invention provides a double-color mold and a forming process of a back door switch, and belongs to the technical field of molds. The problems that an existing mold is low in efficiency and low inprecision when used for forming the back door switch are solved. The double-color mold comprises a rotary table, two rear mold cores which are arranged on the rotary table, synchronously rotate alongwith the rotary table and are of the same structure, a first front mold core arranged above one rear mold core and a second front mold core arranged above the other rear mold core, wherein a first front mold is arranged on the first front mold core, a second front mold is arranged on the second front mold core, a rear mold is arranged at the same position of each rear mold core, and the structuresof the two rear molds are the same. On the basis of the double-color mold, the forming process with a good forming effect is further provided. With adoption of the two rear molds with the same structure, secondary injection molding can be conducted without taking out a product after primary injection molding, the machining efficiency is improved, and the machining precision is improved.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to a two-color mold for a back door switch and a molding process. Background technique [0002] The car trunk switch is also called the back door switch, which is installed on the back door of the car to control the opening and closing of the back door. For example, a Chinese patent discloses a waterproof switch for the trunk of a car [authorized announcement number CN207194629U], which includes a bottom cover, a shell that is fastened with the bottom cover, and a rubber cap on the shell. The PCB board is provided with a micro switch on the PCB board, and a waterproof ring is provided between the bottom cover and the shell. The shell, waterproof ring and rubber cap of the back door switch are molded separately and then assembled. During assembly, the waterproof ring is likely to be skewed, thereby affecting the sealing performance of the back door switch, and the inspection after asse...
