Novel steel wire mesh framework polyethylene composite pipe sealing mold device

Abstract

The invention discloses a novel steel wire mesh framework polyethylene composite pipe sealing mold device, and relates to the technical field of polyethylene pipe processing technologies. The novel steel wire mesh framework polyethylene composite pipe sealing mold device comprises an upper mold pressing plate, a lower mold bottom plate, a T-shaped guide rail, an upper mold, a lower mold, an upper mold and lower mold connecting plate, a left side mold, a right side mold and inclined guide columns, wherein the upper mold pressing plate is connected with the upper mold, one side of the lower mold abuts against one side of the left side mold and one side of the right side mold respectively, the other side of the right side mold can abut against the other side of the left side mold, and one end of the lower mold bottom plate is connected with the lower mold, the left side mold and the right side mold; the two ends of the other side of the upper mold and the two ends of the other side of the lower mold are detachably connected through the upper mold and lower mold connecting plate, and the other side of the left side mold and the other side of the right side mold are detachably connected through the upper mold and lower mold connecting plate; and the left side mold and the right side mold are respectively arranged on the T-shaped guide rail in a sliding mode, the two inclined guide columns are arranged in the upper mold, and inclined guide holes matched with the inclined guide columns are formed in the left side mold and the right side mold respectively. When the novel steel wire mesh framework polyethylene composite pipe sealing mold device is used, the mold locking and opening efficiency is improved, and the mold is convenient to transport and hoist.

Description

technical field [0001] The invention relates to the technical field of polyethylene pipe processing technology, in particular to a novel steel wire skeleton polyethylene composite pipe sealing mold device. Background technique [0002] At present, the sealing technology of steel mesh skeleton plastic composite pipes in the industry generally adopts the plastic ring butt welding sealing technology, which is mainly to butt the plastic ring and the end face of the composite pipe fittings by heat fusion. First, the end face of the network pipe must be polished to make the end face flat and remove the scale. The plastic rings used for welding are lathe-processed, followed by hot-melt welding, and finally the welded parts are trimmed. A total of four processes are required to complete the process. [0003] The applicant finds that there are at least the following technical problems in the prior art: [0004] The welded parts have low firmness and are easy to fall off, resulting i...

AI Technical Summary

Problems solved by technology

[0004] The welded parts have low firmness and are easy to fall off, resulting in low service life of composite pipe fittings

[0005] This welding sealing technology will produce a large amount of plastic powder due to the need to polish the end face of the network pipe, which will easily pollute the working environment

[0006] When the existing mold locking buckle fixes the injection mold, it is easy to slide relative to the mold during the fixing process, which affects the tightness of the fixation, and the mold handling process is difficult and labor-intensive, and it is inconvenient to disassemble

[0007] In addition, the mold opening process of the existing steel mesh skeleton polyethylene composite pipe is relatively difficult, which is likely to cause secondary damage to polyethylene injection molded parts.
