Embodiment Construction

[0018] specific implementation plan

[0019] refer to image 3 , 6, 7, 8, 9, a fixed-length twin-pipe manufacturing mold 7 for winding glass steel pipes, with left and right double mold socket structures, one of which is a fixed end socket 2, and the other is a movable end socket Port 6, movable end socket 6 can be removed freely. The inside of the socket at the movable end is a hollow structure, and a hollow groove 11 is provided, and its function is to reduce weight while minimizing the width of the sealing surface for easy loading and unloading. There are three sets of dovetail grooves 14 at 120-degree intervals on the end surface of the movable end socket facing the fixed end socket 2, and a set of sealing ring components 12 are installed on the movable end socket 6, and the width of the sealing surface 18 is set at 80-150 mm according to the diameter of the pipe. The sealing ring assembly is composed of a sealing steel ring 15 and a heat-resistant rubber plate 16 . The...

Abstract

The invention relates to the technical field of water supply and drainage pipe, in particular to a manufacture die for a fixed-length wound glass steel pipe. The manufacture die mainly solves the technical problem that only one pipe can be manufactured on a die once. According to the technical scheme, a one-die two-pipe manufacture die for the fixed-length wound glass steel pipe is characterized by being provided with a left double-die bellmouth and a right double-die bellmouth, wherein one is a fixed end bellmouth, the other is a movable end bellmouth, and the movable end bellmouth can be detached freely. The manufacture die is mainly used for manufacturing the fixed-length wound glass steel pipe.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage pipes, in particular to a production mold for fixed-length winding glass steel pipes. Background technique [0002] Glass steel pipe is also called glass fiber wound sand pipe. It mainly uses glass fiber and its products as reinforcing materials, unsaturated polyester resin and epoxy resin with polymer components as matrix materials, and inorganic non-metallic particle materials such as quartz sand and calcium carbonate as fillers as main raw materials. Pipes made by craft methods. At present, there are three main molding processes for the production of glass fiber reinforced plastic sand-filled pipes in the world: fixed-length winding process, continuous winding process and centrifugal casting process. At present, the dominant position in the domestic market is the production of FRP pipes by the fixed-length winding method. Its main features are low investment costs and fast t...
