Manufacture method of plastic faucet body

Abstract

The invention discloses a manufacture method of a plastic faucet body. The method comprises the following steps of: (1) machining a metal insert; (2) respectively plugging a first plug and a second plug at both ends of the metal insert; (3) positioning the metal insert in a die cavity for forming a drainage pipe in a die, abutting the first plug on a first male die and abutting the second plug on a second male die; (4) injecting and forming; (5) removing the second plug at the end part of the metal insert and digging a hole in a wall between a valve core seat and an intake pipe; (6) digging a drain hole in the outer periphery of one end of the metal insert arranged in the drain hole end of the drainage pipe; and (7) machining internal threads on the inner wall of the valve core seat. The manufacture method of the plastic faucet body is convenient to machine, can be used for machining a drainage pipe into an elbow, particularly a complicated-shaped elbow of a plastic faucet, and the drainage pipe of the machined plastic faucet body is watertight.

Description

technical field [0001] The invention relates to a method for manufacturing a plastic faucet body. Background technique [0002] Water tap is widely used in daily life, and existing water tap is generally metal water tap, as the water tap that copper material, stainless steel material are made. However, due to the high price of metal materials, the cost of the faucet is relatively high. In response to this problem, people have designed water taps that adopt plastic materials. [0003] The manufacturing method of the plastic faucet body in the prior art includes the following steps: the first step is to process the implanted part according to the shape of the outlet pipe of the plastic faucet to be produced; the second step is to position the embedded part in the mold through the positioning part It is used to form the cavity of the outlet pipe; the third step is injection molding; the fourth step is to open a hole on the wall of the outlet pipe of the formed plastic faucet ...

AI Technical Summary

Problems solved by technology

The manufacturing method of the plastic faucet body of this prior art has the following defects: since it is necessary to open a hole on the pipe wall of the outlet pipe of the formed plastic faucet body, and then use tools to extract the implant from the hole, this process operation It is quite difficult and will reduce production efficiency, and this manufacturing method can generally only be used to manufacture plastic faucets with straight water outlet pipes. If the water outlet pipes are curved pipes, especially curved pipes with complex shapes, the implants cannot be inserted through the holes. Therefore, the shape of the outlet pipe of the plastic faucet is relatively simple; and because the opening on the wall of the outlet pipe is sealed with a plug, if the sealing effect between the seal and the hole wall is not good, water leakage will occur. causing problems for users
