Molding device and preparation method for PVC drainage pipe production

Abstract

The invention discloses a forming device and a preparation method for PVC drainage pipe production. A PVC drainage pipe is manufactured by adopting the preparation method for the PVC drainage pipe, and the production method of the PVC drainage pipe comprises the following steps of preparation of raw materials, allocation of auxiliaries, stirring and mixing, extrusion from a mold, cooling and forming. The forming device for PVC drainage pipe production comprises a feeding device, and an extrusion device is fixedly installed at the bottom of the feeding device; a forming device body is fixedly arranged on the right side of the extrusion device, and meanwhile a cooling device is fixedly installed on the right side of the forming device body; when the PVC pipe enters a cooling pipeline, a switch of a booster pump is started at the moment; external cooling water is injected into a water pipe through the booster pump, and the cooling water enters the cooling pipeline, and is sprayed out from a water outlet in the inner wall of the cooling pipeline for uniformly water-cooling the periphery of the PVC pipe, and cooled water is discharged through a recovery pipe; and subsequent utilization work is facilitated.

Description

technical field [0001] The invention relates to the field of PVC drainage pipe production equipment, in particular to a molding device for PVC drainage pipe production and a preparation method thereof. Background technique [0002] When the plastic pipe in the prior art is extruded, after the material enters the barrel from the hopper of the extruder, under the action of the temperature of the barrel and the rotary compaction and mixing of the screw, it changes from a powdery or granular solid to a solid with a certain flow. After the plastic melt moves to the front end of the barrel, it flows into the machine head (that is, the extrusion die) through the splitter plate under the rotating extrusion of the screw, and forms parts (die) according to the shape of the machine head. , mandrel, etc.) are shaped into high-temperature tubular objects, and the high-temperature tubular plastic sizing device, cooling device, traction device, and cutting device are the plastic pipes requ...

AI Technical Summary

Problems solved by technology

[0005] 1. The cooling device is a rectangular water tank, which occupies an excessively large area and needs to rent a large factory building to increase production costs;

[0006] 2. The cooling device takes a long time to cool the plastic pipe, and the cooling time is generally 30 minutes, which reduces the production efficiency of the device;

[0007] 3. The texture of the plastic pipe just after molding is relatively soft. If it is not cooled in time, it will be deformed and affect the molding quality of the plastic pipe.
