Integrated plastic faucet body forming method

Abstract

The invention discloses an integrated plastic faucet body forming mold. The integrated plastic faucet body forming mold comprises a mold frame, a first static mold cavity, a second static mold cavity and a first moving mold core, wherein the first static mold cavity, the second static mold cavity and the first moving mold core are installed in the mold frame; after the first static mold cavity and the first moving mold core are combined, a first injecting molding is conducted, and a semi-finished product of an integrated plastic faucet is formed; and after the first static mold cavity and the first moving mold core is split, the second static mold cavity is combined with the first moving mold core, then a second injection molding is conducted, and a finished product of the integrated plastic faucet is formed. By adopting a manufacturing method of twice injection molding and integrated cladding forming in the finished product, the manufacture method is simple, producing efficiency and the yield of the finished product are high, the effect of fast and mass production is achieved, producing cost is reduced, and a metal connecting pin is added, so that a product is more firm, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of faucet manufacturing, in particular to a molding method for an integrated plastic faucet body. Background technique [0002] In the prior art, most household faucets are faucets with cold and hot water inlet pipes where the water outlets merge together to mix water. The inner core structure of the faucet is composed of two vertical pipes and a horizontal pipe connecting the two vertical pipes. The middle part of the pipe is a mixed water outlet to match the regulating valve. [0003] At present, there are roughly two production methods for faucet body components on the market. The first production method is to directly adopt the casting production method. The production method is complicated and lengthy, the processing time is long, the efficiency is not high, and the yield is also low. In addition, copper integral casting is used. Although it can meet the requirements of installation strength, due to th...

[0003] At present, there are roughly two production methods for faucet body components on the market. The first production method is to directly adopt the casting production method. The production method is complicated and lengthy, the processing time is long, the efficiency is not high, and the yield is also low. In addition, copper integral casting is used. Although it can meet the requirements of installation strength, due to the lack of resources and the high price of metal, the material cost of the faucet is relatively high, which is not economical and cost-effective.

[0004] The second production method is to make injection molding to make the two side components formed by the valve seat and the foot part on both sides of the faucet component, and the long hollow component at the middle connection part, and then glue them to the opposite parts to form the faucet body. Components; although one-time injection molding can overcome the flow channel in the middle connection part of the molding, it requires a lot of manual bonding and production, and the strength of the bonding part is relatively poor, and the glue is prone to qualitative changes, which seriously affects the quality and service life of the product.
