[0037] refer to figure 1 and combine image 3 , The invention provides a water outlet pipe of a faucet and a manufacturing process thereof. The water outlet pipe in the present invention includes a base body with an inner layer, and a composite layer of plastic material covering the outside of the base body. The metal matrix composite material layer covers the base body by injection molding. The main body of the base in this embodiment is zinc alloy, which has a low melting point and good fluidity, and has relatively low manufacturing process requirements, that is, low manufacturing cost. The plastic material composite layer is a plastic material composite layer prepared by mixing polymer plastic materials, metal powder, fibers, additives and graphene. Wherein, the selected proportions of the components of the plastic shell 0102 are: 30%-60% of polymer plastic materials, 10%-20% of fibers, 0.8%-3% of additives, 0.5%-5% of graphene %, the balance of metal powder. In this e...

[0056] combine Figure 3 to Figure 11 , the above-mentioned first embodiment has provided a process that can produce qualified water outlet pipe components. In the above step D, when the first opening 0103, the second opening 0104 and the third opening 0105 on the water outlet pipe are processed, the processing eccentricity often occurs, and the eccentric positions of the holes processed by different batches of products are different. It is different (for example: one side of the hole is not processed enough to cause black skin, and the other side is processed too much, causing the wall thickness of the other side of the casting blank 0101 to be thinner). After verification, the inventor found that the reason for this is that every time during production, in step B, when the casting blank 0101 formed in step A is fixed in the molding cavity of the injection mold 06, its fixed angle will be Changes occur, and the changes lead to changes in the machining allowance at the same p...

[0068] The present application further provides a third embodiment, which achieves a technical effect similar to that of the second embodiment. combine Figure 5 , Figure 6 as well as Figure 8 Specifically, the first limiting mechanism 07 includes a first limiting member used to limit the position of the first opening 0103 in the first direction, and cooperates with the first limiting member to define the position of the second opening 0104 in the first direction. The second limiting member is a desired distance L1 away from the first opening 0103 in the direction. The first limiting member includes a first end surface 0108B located at the first opening 0103 on the casting blank 0101, a first positioning portion 0302 configured on the injection mold 06 to abut against the first end surface 0108B, and a second limiting member It includes a second end surface 0109B located at the second opening 0104 on the casting blank 0101, a second positioning portion 0402 configured on ...

Abstract

The invention relates to a water outlet pipe molding process, which is used to form a first water outlet pipe including a base body located in the inner layer and formed by casting and processing, and a plastic shell wrapped on the outside of the base body and formed by injection molding. The process includes the following steps, S01: integrally molding the casting blank of the inner layer through a casting mold; S02: performing a first heat treatment on the casting blank in an air atmosphere at a temperature of T02, and the time is t1, wherein, the first 1. The heat treatment temperature is not lower than 60°C; S03: Fix the casting blank with a temperature of not lower than 55°C as a core in the molding cavity of an injection mold, and the inner surface of the molding cavity follows the outer surface of the casting blank. Surface; S04: Inject molten plastic into the molding cavity to cover the exterior of the casting blank; S05: Perform a second heat treatment on the second outlet pipe at a temperature of T03; S06: Apply The opening of the tee pipe on the casting blank is processed.

Description

technical field [0001] The invention relates to the bathroom industry, in particular to a forming process for a water outlet pipe of a faucet. Background technique [0002] Most of the existing faucets are formed by metal casting or metal pipes are welded and combined by machining, and some of them are integrally formed by injection molding of plastic materials. Metal faucets are more durable and have a metallic texture, but the cost is high, and the rough surface of the cast blank needs to be polished and shaped during the production process. The process is complex and difficult, time-consuming and laborious. The molding process of plastic faucets is simple and does not require complex processes such as grinding and shaping. However, plastic faucets are light in weight, poor in strength, and lack the texture of metal, so they cannot attract customers to buy in the first place. In order to solve this problem, the inventor proposes a water outlet pipe of a faucet with a meta...
