AI Technical Summary

Technical Problem

During the production process of the existing light-touch switch base, the solidified plastic outer surface at the interruption between the first communication part and the second communication part is prone to unevenness, resulting in wear of the connecting brush on the swing rod and reducing the service life of the product.

Method used

The method of injection molding in batches is adopted. First, the workpiece is placed horizontally, and the lead rack is formed through stamping. Then the first injection molding is performed. After the plastic is solidified, the bending and cutting treatment is performed. Finally, the second injection molding is performed to ensure that the plastic outer surface of the interrupted parts of multiple connecting plates is flat.

Benefits of technology

Through the injection molding method in batches, the unevenness caused by gravity flow of plastic is avoided, the service life of the product is extended, and the overall strength of the base is improved.

Abstract

The present application relates to a method for manufacturing a touch switch base, comprising the following steps: S1: placing a workpiece horizontally at a designated position of a workstation; S2: stamping the workpiece, and forming a lead frame on the workpiece, and the lead frame includes a fixed plate and a plurality of connecting plates; S3: injecting molten plastic into the position where the workpiece is located, and allowing the plastic to flow into the discontinuities where the connecting plates are close to each other and the discontinuities where the connecting plates and the fixed plates are close to each other, and waiting for the plastic to solidify; S4: making the discontinuities where the connecting plates are close to each other perpendicular to the horizontal plane; S5: injecting molten plastic into the position where the workpiece is located, and waiting for the plastic to solidify. The present application has the effect of making the outer surface of the plastic at the discontinuity between the first connecting portion and the second connecting portion smoother.
