Embodiment 1

[0030] like Figure 1 to Figure 5 As shown, a sealing insert structure of a two-color mold includes an insert body 1, a boss 2 and an insert 3, wherein the insert body 1 and the boss 2 are integrally formed. The insert body 1 is provided with a first mounting portion 11 and a second mounting portion 12 , the first mounting portion 11 and the second mounting portion 12 are fixedly connected, for example, integrally formed, and the boss 2 is fixedly mounted on the upper surface of the first mounting portion 11 , the insert 3 is installed on the side surface of the second mounting portion 12 , and the insert 3 is inserted into the second mounting portion 12 . In this embodiment, the direction of the insert body 1 close to the boss 2 is taken as the upper direction, the second mounting portion 12 is a rectangular parallelepiped structure, the upper surface and the side surface of which are both flat, and the insert 3 is provided with the second mounting portion 12 . The side face...

Embodiment 2

[0035] like Image 6 As shown in the figure, a method for using the sealing and inserting structure of a two-color mold adopts the above-mentioned sealing and inserting structure, and the use method includes the following steps:

[0036] S1: Insert and repair the insert piece 3 and the insert body 1 so that the front and rear sides of the insert piece 3 and the front and rear sides of the insert body 1 are kept on the same plane respectively to form an assembly.

[0037] S2: Install the insert body 1 of the assembly into the reserved installation position in the fixed mold 4, and then perform the repairing, so that the upper end surface of the second installation part 12 is flush with the surface of the fixed mold 4, and the insert 3 will be fixed to the fixed mold 4. The feed channel 41 in the die 4 is blocked.

[0038] S3: Remove the assembly from the fixed mold 4, then turn the assembly over so that the boss 2 faces down, install the boss 2 and the insert 3 into the reserved...

Abstract

The invention discloses a glue sealing insert structure of a double-color mold, which comprises an insert body provided with a first mounting part and a second mounting part, and the first mounting part is fixedly connected with the second mounting part; the boss is fixedly mounted on the upper surface of the first mounting part; the inserting piece is mounted on the side face of the second mounting part, and the inserting piece is connected with the second mounting part in an inserted mode. According to the method, the repairing process can be simplified, accumulated errors are reduced, and the mold repairing efficiency and precision are improved.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a sealing insert structure of a two-color mold and a method for using the same. Background technique [0002] In the automotive lamp manufacturing industry, the two-color and multi-color tail lamp shades are mostly spliced, and the product molds are sealed in the form of pin inserts. Traditional pin inserts are generally composed of insert body and inserts. The repair method is as follows: firstly, the body of the insert and the insert are first matched, then the whole of the insert and the fixed mold are repaired, and finally the whole of the fixed mold and the whole of the movable mold are repaired. The traditional repair method of pin inserts requires the overall repair of the movable and fixed molds, and the workload is large. At the same time, due to the assembly gap between the various structures of the mold, the overall repair method will lead to a large cumulative error. ...
