Plastic faucet body and manufacturing die thereof

Abstract

The invention discloses a plastic faucet body and a manufacturing die, which belong to the technical field of machinery and aim to provide the plastic faucet body with good sealing performance. The plastic faucet body comprises a left water inlet pipe and a right water inlet pipe, wherein a left valve seat installation groove is formed in the left water inlet pipe, a right valve seat installationgroove is formed in the right water inlet pipe, a connecting cross beam is arranged between the left water inlet pipe and the right water inlet pipe, a water outlet is formed in the connecting cross beam, a middle waterway is formed in the connecting cross beam, the middle waterway communicates with the left water inlet pipe, the middle waterway communicates with the right water inlet pipe, the middle waterway communicates with the water outlet, the middle waterway comprises a left water inlet way and a right water inlet way, and the left water inlet way and the right water inlet way are in curved or U shapes. The plastic faucet body can be used for assembling various cold water and hot water mixed faucets and has the advantage of good sealing performance, and additionally, the plastic faucet body is integrally formed, so that the procedure is simplified, the cost is reduced, and the production efficiency is improved.

Problems solved by technology

[0002] The body of the existing faucet is usually roughly H-shaped, including two valve seats, left and right, and a connecting part between the valve seats; each valve seat is formed with a mounting groove, which can be used for a valve respectively. Body installation, and each relative valve body can be controlled by a handle; a central flow channel is formed in the connection part, and its two ends are respectively connected to the installation groove of the valve seat part, and at least one water outlet is provided in the middle to communicate with the central flow channel. Flow channel, the water outlet can be connected to water outlet components such as faucet outlet pipes or showers; the current faucet body structure is mostly made of metal copper integrally cast, but there are complex processes,

Disadvantages of poor sealing and high cost

[0003] In order to overcome the shortcomings of metal faucets, there are currently related technologies that use secondary injection molding technology, but the secondary injection molding has the problem of leakage of the injection molding joint surface. The invention with the notification number CN201475461U discloses an injection molding structure for the inner core body of the faucet. The injection molding structure The main body of the integrally formed water channel is provided with a cold water inlet pipe and a hot water inlet pipe. There are cold water inlet channels and hot water inlet channels on the cold water inlet pipe and the hot water inlet pipe. There is a crossbeam connected between the cold water inlet pipe and the hot water inlet pipe. There are lateral core-pulling channels connected to the cold water inlet channel, lateral core-pulling channels connected to the hot water inlet channel, and water outlets, and the above-mentioned lateral core-pulling channels connected to the cold water inlet channel The interlinked lateral core-pulling channels and water outlets form an internal three-way integrated water channel body, and the lateral core-pulling holes on the integrally formed water channel body are provided with sealing plugs

However, the water channel of the faucet body of the above-mentioned patent still needs seals such as sealing plugs and sealing rings to seal the body of the faucet, resulting in a decrease in the sealing performance of the water channel of the faucet body, and there is a hidden danger of water leakage. The ring is installed on both sides of the spool, but due to the complex core-pulling process, the production efficiency is low and the yield is low, so it cannot be applied to mass production
