Abstract

The invention relates to a no-mark ejection molding die for an automobile light guide strip. The forming mold includes a fixed mold assembly, a movable mold assembly, an injection device, an ejector and a core assembly, and the movable mold assembly is closed to the fixed mold assembly and forms a mold cavity with the core assembly. The mold cavity includes a light guide cavity, a bracket cavity connected to one end of the light guide cavity and a connection cavity connected to the other end of the light guide cavity, and the bracket cavity is located in the injection direction of the injection device. The ejector device includes a first ejector assembly and a second ejector assembly that are slidably connected to the fixed mold assembly, the connecting cavity is located in the sliding direction of the first ejector assembly, and the bracket cavity is located at the Describe the sliding direction of the second ejector assembly. The injection device injects raw materials in the mold cavity and the injection position is located at the cavity of the bracket, so as to avoid injection marks in the light guide cavity. The ejection device abuts against the installation positions of the light guide strip corresponding to the connection cavity and the bracket cavity respectively, so as to avoid forming ejection marks in the light effect area of ​​the light guide strip.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a non-mark-out mold for automobile light guide strips. Background technique [0002] Automotive light guide strips are used to transmit light in a directional manner to improve the light efficiency during vehicle driving and improve the user's visual experience. In order to ensure the output light efficiency of the automobile light guide strip, the existing processing mold is provided with a connected ejection cavity on both sides of the cavity for making the light guide strip. The ejection cavity is used to cooperate with the ejection mechanism to eject the light guide strip. In order to avoid the indentation left by the thimble ejection in the light effect area of ​​the light guide strip. However, the ejection edge corresponding to the ejection cavity is distributed on both sides of the light effect area of ​​the light guide strip, and the ejection edge only plays the role of e...
