Preparation process of integrated shower head surface cover

Abstract

The invention relates to the technical field of shower heads, in particular to a preparation process of an integrated shower head surface cover. The preparation process comprises the following steps that S1, an annular glue sealing groove with the width of 0.4-0.6 mm and the thickness of 0.1-0.3 mm is reserved in the circumference of an outer ring of each nozzle hole of the shower head surface cover, and then injection molding is conducted to obtain a shower head surface cover body; S2, a metal layer is plated on the surface of the shower head surface cover body; and S3, the glue sealing position of a mold can exactly press the annular glue sealing groove, after secondary injection molding, the surface of the nozzle hole of the shower head surface cover body is coated with a plurality of TPE nozzles, and the back of the nozzle hole is coated with a TPE gasket with a water sealing function. According to the prepared integrated shower head surface cover, the nozzle coated through secondary injection molding and the metal layer can be well combined, sealing is good, so that the mode that other parts and the nozzle are assembled is not needed, the assembling procedure is greatly simplified, the product size is small, and the appearance quality is improved.

Description

technical field [0001] The invention relates to the technical field of showers, in particular to a preparation process of an integrated shower cover. Background technique [0002] Existing showers mainly include a body and a cover. The cover is often designed with soft rubber material (such as plastic) as the nozzle and then embedded in the cover. Thereby reducing the chance of the nozzle being clogged. [0003] The cover structure adopts the above-mentioned embedded nozzle, wherein the cover body is one-time injection molding, and then the soft rubber nozzle is separately injected, and then the molded nozzle parts are installed on the cover body one by one. However, in the actual production process, in order to prevent oxidation and rust of the surface cover and play an aesthetic role, it is also necessary to perform electroplating on the surface of the injection-molded surface cover body, so the following problems will occur: the surface cover body after electroplating T...

AI Technical Summary

Problems solved by technology

However, in the actual production process, in order to prevent oxidation and rust of the surface cover and play an aesthetic role, it is also necessary to perform electroplating on the surface of the injection-molded surface cover body, so the following problems will occur: the surface cover body after electroplating The surface layer is covered by the metal layer, which makes it difficult for the nozzle to be combined with the metal surface layer of the cover body. If the combination of the two is not good, it is prone to water leakage

[0004] However, adopting the above-mentioned assembly structure requires dismantling parts and adding new parts (support frame, etc.), which will increase the volume of the product, complicate the structure, and increase the number of assembled parts and assembly processes, resulting in higher product costs.
