A tee pipe and its injection mold and method

Abstract

The invention relates to the technical field of molds, and discloses a three-way pipe injection mold. The three-way pipe injection mold comprises a top plate, an upper mold base, a lower mold base, anupper mold and a lower mold, wherein a glue injection port is formed in the middle of the top plate, the upper mold base is arranged below the top plate, a glue injection pipe is arranged in the middle of the upper mold base, the glue injection pipe communicates with the top of the upper mold, an upper mold groove is formed in the bottom surface of the upper mold base, the upper mold is arrangedin the upper mold groove, a first three-way core groove and a second three-way core groove are formed in the bottom surface of the upper mold, and the lower mold base is matched with the upper mold base; a first core pulling assembly groove, a second core pulling assembly groove, a third core pulling assembly groove and a lower mold groove are formed in the lower mold base, and are correspondinglyprovided with a first core pulling assembly, a second core pulling assembly and a third core pulling assembly, and the lower mold groove is formed in a joint of three core pulling assembly grooves. The three-way pipe injection mold and the method have the beneficial effects that a main pipeline and a branch pipeline in three pipelines of the injection mold are arranged on different planes, an occupied space is saved, the connecting strength is further increased, and meanwhile the service life is prolonged.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a tee pipe injection mold. Background technique [0002] The three-way pipe is used at the branch pipe of the main pipeline. The three-way pipe is a pipe fitting with three openings, namely one inlet and two outlets; or two inlets and one outlet. There are T-shaped and Y-shaped pipes with equal diameters. Nozzles, also with different diameter nozzles, are used for the confluence of three same or different pipelines. The main function of the tee is to change the direction of the fluid. [0003] Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained. Injection mold is an important process equipment for the production of various industrial products. With the rapid dev...

Problems solved by technology

However, the three joints of the tee injection mold and most of the tee pipe injection molds are on the same plane. If the space is limited, such a tee is inconvenient or even impossible to use. And injection molding the tee with the main pipe and branch pipes not on the same plane can further increase the structural connection strength and increase the service life
