Hollow integrated type plastic faucet water-channel part and preparation method thereof

Abstract

The invention provides a hollow integrated type plastic faucet water-channel part and a preparation method thereof and relates to a faucet. The hollow integrated type plastic faucet water-channel part is provided with a cold / hot water inlet part and a cold / hot water outlet part, which are integrated with each other, wherein the cold / hot water inlet part and the cold / hot water outlet part, which are integrated with each other, are connected in a welding form and are both formed in a core-melting casting manner. The preparation method comprises the following steps: mounting an easily melted core; assembling a mould and injecting; curing the part and melting the core; casting the core; opening the mould and taking out the part; cleaning the part; and welding the part. According to the preparation method, a hollow irregular entire structural part which cannot be subjected to core pulling can be produced; the integrity of the water-channel part is increased; the hollow shaping of thermosetting plastic is realized; the mould structure is simplified; the mould cost is lowered; the core-melting casting and part-shaping streamline continuous production is realized; the curing for the part, the melting for the easily melted core and the casting for the easily melted core are combined and performed at the same time; the heat energy is fully utilized; the production cost is lowered; and the production efficiency is increased.

Description

technical field [0001] The invention relates to a faucet, in particular to a hollow integrated plastic faucet water channel part and a preparation method thereof. Background technique [0002] The conventional plastic injection molding method is to use steel to make the core and cavity and combine the structural parts to form a mold with the same shape as the part, and inject the part on the injection molding machine. When opening the mold to take the part, the mold must be pulled out first. Core, the workpiece can be taken out. For complex parts, multiple or even different directions of extractable cores are sometimes required. The mold structure is very complicated like this, and it is very difficult to design and manufacture. For parts with special shapes, such as special-shaped bottom-sealed holes with large inner openings and small openings, core pulling cannot be achieved, and integral parts cannot be injection molded at one time. When injection molding plastic part...

AI Technical Summary

Problems solved by technology

Such a mold structure is very complicated, and it is very difficult to design and manufacture.

For parts with special shapes, such as special-shaped bottom-sealed holes with large inner openings and small openings, core pulling cannot be achieved, and integral parts cannot be injection molded at one time.

When injection molding plastic parts that are structurally difficult to release, such as hollow plastic parts with complex shapes such as automobile fuel pipes and intake and exhaust pipes, they are generally divided into two halves and then put together again. In some cases, the requirements can be met, but in many cases, some problems are caused by poor sealing and increased external dimensions
