Abstract

The invention discloses a cooling mechanism for a threaded shaft of a water feeding pipe die. The cooling mechanism comprises a fixed die seat plate and a movable die seat plate, wherein a fixed die fixing plate, a fixed die gear plate, a fixed die bearing plate and a cavity plate are arranged below the fixed die seat plate; a cavity threaded shaft is arranged in the cavity plate; a die foot is arranged on the movable die seat plate; a movable die gear plate, a movable die bearing plate and a core plate are arranged on the die foot; a core threaded shaft is arranged in the core plate; the head of the core threaded shaft corresponds to that of the cavity threaded shaft; the core threaded shaft and the cavity threaded shaft respectively form a cavity together with the cavity plate and the core plate; a formed pipe is arranged in the cavity. The cooling mechanism is characterized in that water sealing glands are arranged at the end parts of the cavity threaded shaft and the core threaded shaft; framework sealing rings are arranged in the water sealing glands; lips of the framework sealing rings are in contact with the outer walls of the end parts of the cavity threaded shaft and the core threaded shaft; cooling water pipes are respectively arranged in the cavity threaded shaft and the core threaded shaft; cooling water holes are formed in the water sealing glands; the cooling water pipes are communicated with the cooling water holes.

Description

technical field [0001] The invention relates to a cooling mechanism for a threaded shaft of a water supply pipe fitting mould, which belongs to the field of plastic pipe fitting moulds. Background technique [0002] At present, in the production of threaded water supply pipe fitting molds, the thread demoulding of pipe fittings generally uses an automatically rotating threaded shaft (core), which is driven by an electric motor or an oil motor through a gear. In the prior art, since the threaded shaft needs to be rotated when demoulding, the rotating threaded shaft cannot be directly connected to the inlet and outlet of the cooling water pipe (the leather pipe of the cooling water circuit will be entangled when rotating), so designing the cooling water channel in the rotating threaded shaft becomes a problem. It is a difficult task, but the heat generated in the production of pipe fittings cannot be cooled in time, which will easily affect the shaping cycle of the pipe fittin...
