Abstract

The invention relates to a method for assembling an automobile gauge point. The method is realized by the following steps: putting an injected molding component point into a lower cavity plate of a needle guard; positioning a point in the cavity by two positioning holes on the point and two positioning nails on the lower cavity plate; after an upper cavity plate of the needle guard and the lower cavity plate are connected, the point is completely coated by plastics; and combining the point and the needle guard by injection; and staying the molded combined part in the lower cavity after the upper cavity plate and the lower cavity plate are separated, and separating the product and the die by an ejector. The method has the advantages that the problem of match of all components in assembly can be solved so as to improve the yield of products because the point and the needle guard form into a part; and the unqualified rate of the products is reduced to below 5 per mill from the original 10 percent so as to improve the working efficiency of the company.

Description

technical field

[0001] The invention relates to a pointer of an automobile meter, in particular to an assembly method of a pointer and a needle cover in the pointer of the automobile meter. Background technique

[0002] There is a large amount of data on the vehicle body, and the coordination workload of each component and part is even greater. Frequent data changes often occur, which is a normal phenomenon during the development process.

[0003] For the mold development factory, it must be accepted unconditionally, and it must be quickly implemented in the mold development process. This leads to more changes in mold development, involving changes in mold development plans, design changes, and manufacturing changes. However, automobile OEMs generally do not change the construction period, requiring the mold development factory to ensure the construction period according to the quality requirements, which puts forward strict requirements for the mold development factory. ...
