Embodiment Construction

[0007] Before implementing the following processes, it is carried out on the basis of the preliminary preparations for injection molding. In addition to the preliminary preparations for ordinary injection molding, nitrogen control equipment and high-pressure nitrogen booster systems must be added, and injection molds must be equipped with gas injection nozzles, air channels and The external nozzle, on this basis, the specific implementation process is as follows:

[0008] 1. Put inserts: Generally, the mold of the faucet has inserts, and inserts should be placed before injection molding.

[0009] 2. Mold closing.

[0010] 3. Injection: According to the amount of injection, the injection time and gas injection time should be set before injection, and the injection should enter 60%-95% of the cavity.

[0011] 4. Gas injection: Gas injection is to inject high-pressure nitrogen into the plastic melt of the mold cavity through the nitrogen console and the gas nozzle in the mold un...

Abstract

The invention relates to a production process of a single-handle basin plastic tap main body. The process comprises the following steps: placing an insert, folding a model, injecting materials, injecting air, keeping the pressure, releasing the air, cooling, unfolding the mold and taking out a part. Through the above procedures, the produced plastic tap can not pollute water quality. The injection process does not need too high pressure. Therefore the module has a simple structure and long service life, needs no large injection machine, and has low loss. Since part high pressure air is discharged in the injected part, the material is saved and the construction cost is low.

Description

technical field [0001] The invention relates to a production process for a main body of a single-handle basin plastic faucet. Background technique [0002] Existing water taps utilize metals such as brass, zinc-silicon alloys, and aluminum alloys to form through casting processes. Because they are made of metal materials, they are easy to rust, pollute water quality, and have a high cost. Contents of the invention [0003] The purpose of the present invention is to provide a production process for the main body of a single-handle basin plastic faucet. The faucet produced by this process does not pollute the water quality, has low cost, and the mold structure is simple, the mold has a long service life, no large injection molding machine is needed, and the mold loss is small. . [0004] To achieve the above object, the present invention adopts following technology: [0005] Put the insert→close the mold→injection→gas injection→hold pressure→gas release→cooling→open the mo...
