[0002] A water divider is a device used to divert fluids. It is usually used in piping systems to direct fluids into different pipes or channels to achieve fluid diversion and control. It is widely used in various fields such as life and production. Water dividers are usually injection molded. Traditional water divider injection molds use one-piece molding molds. Since there are many branches in the injection molding process of water dividers, the one-piece molding method may have defects and the process debugging is more difficult.

[0003] In order to overcome the above disadvantages, the prior art integrates the branch pipe into the side of the main pipe by partially injecting the main pipe. For example, Chinese patent application No. 201010527657.5 discloses a method for injection molding of a plastic manifold, in which the branch pipe is injection molded into the side of the main pipe by a secondary molding method. Specifically, the secondary injection molding is to firstly injection mold the plastic main pipe, and reserve or open a manifold installation hole, insert the metal joint into the mandrel of the water outlet of the rear mold and set it in the installation hole, and finally inject the installation hole again to form the plastic main pipe and the metal joint into one piece.

[0004] The branch pipe spacing corresponding to the injection mold in the above solution is fixed. Different users have different requirements for the branch pipe spacing. The injection mold in the above solution is not universal. In order to meet customer needs, new molds can only be opened, which increases costs. Utility Model Content
