Problems solved by technology

However, because the mold used to manufacture the faucet is an integral structure, the inside of the mold has a shape that matches the body of the faucet. Once the raw materials injected into the mold are solidified during the manufacturing process, the mold can be removed. However, because the faucet has an extension The overall shape of the part is a special-shaped structure, which makes it difficult to remove the formwork, thus affecting the yield of the product

Embodiment 1

[0059] This plastic faucet is made according to the following process:

[0060] A. Parts production: make plastic faucet parts, including connecting pipe 5, water inlet seat 6, water outlet seat 7, valve core seat 4, water inlet pipe 2, water outlet pipe 3, valve core, valve stem and handle. Wherein spool seat 4, water inlet pipe 2, water outlet pipe 3, spool, valve stem and handle are common parts, can adopt common processing technology to make, also can directly buy in the market.

[0061] The blanks of the water inlet seat 6 and the water outlet seat 6 with basic shapes are made by casting or directly machining, and then the above-mentioned blanks are processed by turning, wherein the thread turning tool is used on the water inlet seat 6 and the water outlet seat 7 Process the internal thread, thereby manufacturing the water inlet seat 6 and the water outlet seat 7. Select a pipe with an appropriate pipe diameter, and cut several pipe sections that meet the length, so as t...

Embodiment 2

[0071] In this embodiment, the curing time of the plastic in Step E is 11 minutes, and the others are the same as in Embodiment 1.

Embodiment 3

[0073] In this embodiment, the curing time of the plastic in Step E is 20 minutes, and the others are the same as in Embodiment 1.

[0074] The present invention also provides a mold used in the process of manufacturing a plastic faucet, the mold is composed of an upper mold body 8 and a lower mold body 9, the upper mold body 8 and the lower mold body 9 have a concave mold cavity 10 inside, the mold There is also an inlet 17 on the top. In this embodiment, the material inlet 17 is composed of an upper groove 8b located on the upper mold body 8 and a lower groove 9c located on the lower mold body 9. After the upper and lower mold bodies 8 and 9 are covered, the upper groove 8b and the lower mold body The groove 9c forms a material inlet 17 whose size gradually decreases from the outside to the inside, as shown in FIGS. 6 to 12 .

[0075] The upper mold body 8 and the lower mold body 9 are provided with positioning holes that penetrate to the mold cavity 10. The positioning hol...

This invention process method comprises the following steps: a, parts processing; b, parts assembling; c, mode fixing; d, mode integrating; e plastic injection; f, surface processing; g, assembling product.

Description

technical field [0001] The invention relates to a water faucet, in particular to a plastic water faucet, a production process for manufacturing the plastic water faucet, and a mold used in the production process. Background technique [0002] The body of the traditional faucet is made by casting metal materials, and then the surface of the cast body blank is polished and plated with a metal protective layer of nickel or chromium, and finally assembled with valve core, valve stem, handle and other parts. for the faucet. [0003] It can be seen that the metal protective layer can prevent the main body from rusting and enhance its appearance. However, adopting this manufacturing method consumes a large amount of metal materials, which makes the manufacturing cost of the faucet relatively high. Simultaneously, the metal protective layer has a single color, which cannot satisfy people's individual needs. [0004] For the problems referred to above, people have designed water t...
