Injection mold for three-way pipe

Abstract

The invention discloses an injection mold for a three-way pipe. The injection mold comprises a bottom fixing base, mold supporting legs, a handheld moving plate, a mold core and an afterteeming sealing stop block. The mold supporting legs are arranged on the bottom fixing base. A lower mold body is mounted on the mold supporting legs. The handheld moving plate is arranged on one side of the lowermold body. Bolt mounting holes are formed in the top of the lower mold body. A mold core stop block is mounted on one side of the bolt mounting holes. The mold core is mounted on one side of the moldcore stop block. An afterteeming pipeline is mounted above the mold core. The injection mold for the three-way pipe has the beneficial effects that an arc-shaped mold ejection head is arranged to eject the mold core so that the three-way pipe can be taken out of the mold conveniently after being formed; the temperature of an injection molding liquid storage tank can be maintained, so that the problem that injection molding liquid is solidified due to temperature drop is effectively solved; and the afterteeming pipeline is arranged so that afterteeming can be conducted when the three-way pipe is not completely cast, and the forming quality of the thee-way pipe is ensured.

Description

technical field [0001] The invention relates to the field of injection mold equipment, and the invention relates to an injection mold for a three-way pipe fitting. Background technique [0002] A pipe joint with three openings is called a tee. Tee pipes are widely used in pipe networks for conveying liquids and gases. Due to the different conveying media, the material of the tee pipe is divided into: cast iron, cast steel, cast copper, cast aluminum, plastic, glass, etc. Tees made of plastic are usually injection molded, so a tee injection mold is required. [0003] The application number is: 201510403227.5 Chinese patent, which discloses a tee pipe injection mold, including the mold frame structure and the first, second, third and fourth core-pulling and demoulding mechanisms of the mold core-pulling and demoulding parts , The first and second core-pulling and demoulding mechanisms are the same oil cylinder driving a double-linkage mechanism, and the third and fourth are...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned patents, the mold cannot be ejected during the injection molding of the three-way pipe, which will easily cause the three-way pipe fittings to adhere to the inside of the mold, and the injection liquid cannot be kept warm, which will easily cause the injection liquid to condense due to the drop in temperature. lead to blockage of injection pipe
