[0024] As Figures 1-6 shown, the utility model provides a kind of automobile lamp parts mould with replacement structure, including injection mold main body 1, injection mold main body 1 detachably connected with replaceable insert 2, the production of different products is realized by replacing replaceable insert 2, replaceable insert 2 includes insert A 201 and insert B 202, the production of product A 3 and product B 4 is realized by replacing two inserts A 201 and insert B 202.

[0025] Here expounds the key advantage that the structure of the utility model possesses, that is, using the form of injection mold insert replacement, only a pair of mould can realize the production of two different products.

[0026] Specifically including following content:

[0027] First, injection mold main body 1, it is the basic framework of entire mould structure, provides a stable platform and basic space structure for the installation of subsequent parts and injection molding production process.

[0028] Second, insert A 201 and insert B 202, these two inserts are the key components to realize the production of different products, they can be replaced in mold body.

[0029] Finally, product A 3 and product B 4, this is the two different products that are finally produced by mould. By respectively replacing insert A 201 and insert B 202 and installing in injection mold main body 1, product A 3 and product B 4 can be respectively produced (the difference between the two products is noted in the drawing, that is, product A 3 is 25mm longer than product B 4).

[0030] In conclusion, the utility model discloses a pair of plastic parts injection moulds can be designed for two kinds of automobile lamps with regular shape and linear difference, and the purpose of producing two kinds of products can be realized by replacing the insert block, and a pair of moulds does not need to be developed for the parts.
