Base type non-metal water tap

Abstract

This invention discloses a seat type non-metal water cock. It includes cock body case, in which has water inlet passage and water outlet passage. The water inlet passage includes cold and hot water inlet passages. The cold and hot water inlet passages are all arranged with water inlet joint. They also include excessive smooth arc passage. Arc core-pull bar, which works as one part of the core-pulling mould, can undertake core-pulling without any obstacles. It resolves the core-pulling question of cold and hot water inlet passages. The whole water cock body case can be produced by mould injecting and core-pulling techniques. The produces cock does not need additional assembling. Its fastness is increased. The cost is also low.

Description

technical field [0001] The invention relates to a water faucet, especially a seat-type plastic water faucet with hot and cold water inlet channels which can be manufactured by injection molding. Background technique [0002] The seat type faucets currently on the market are generally faucets made of metal materials. This type of faucet generally needs to be manufactured by sanding process. Due to the high cost of metal materials, especially copper, the operation of sanding process is complicated and labor-intensive, which leads to Its cost is higher. [0003] In view of this, there is also a plastic faucet with a single water inlet pipe and a column-type plastic faucet. However, due to the limitation of the core-pulling process, it has not been possible to manufacture a seat-type plastic faucet. The bending is complicated and the core cannot be pulled, and the seat faucet is also a mainstream style of faucet at present. Contents of the invention [0004] The technical pr...

Problems solved by technology

[0006] Since the hot and cold water inlet passages of the water inlet passage of the seat type non-metallic faucet provided by the present invention all include smooth and excessive arc-shaped passages, if the general passage is composed of arc-shaped passages, the arc-shaped core-pulling as a part of the core-pulling mold The rod can be core-pulled without obstacles. After solving the problem of core-pulling of the hot and cold water inlet channels, the entire main body of the faucet can be manufactured very smoothly using the process of mold injection and core-pulling. The main shell of the faucet is integrally formed, no additional installation is required, and the firmness is improved. This process consumes less man-hours than the general foundry process, and the material used for injection molding can also be selected. The cost is much lower than most metals. Made of plastic, etc., so the processing cost of seat faucet can be greatly reduced, and the processing speed is much faster
