Description

Technical Field

[0001] This invention relates to the field of corrugated pipe injection molding technology, and in particular to an extrusion molding equipment for corrugated pipe production and processing. Background Technology

[0002] A corrugated pipe is a tubular connector with foldable corrugations that can expand and contract along the folding direction. It is a cylindrical, thin-walled corrugation with multiple transverse corrugations, capable of displacement under pressure, axial force, lateral force, or bending moment. Corrugated pipes have a wide range of applications. Currently, corrugated pipes are mainly manufactured through integral casting, requiring the raw material to be pre-introduced into the molding device via an extruder and pipes. This process involves a long extrusion stroke, a large structural footprint, significant energy loss, and a long cooling stroke, resulting in low equipment molding efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the current corrugated pipes are mainly processed and produced by integral casting molding. The raw materials need to be fed into the molding device through the pipe using an extruder in advance. Not only is the extrusion stroke relatively long, but the structure also occupies a large area and the energy loss is relatively serious. At the same time, a large cooling stroke is required, resulting in low molding efficiency of the equipment.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an extrusion molding equipment for corrugated pipe production and processing, including a first frame, a second frame, a first electrically controlled conveyor belt installed on the first frame, and a second electrically controlled conveyor belt installed on the second frame. A horizontal extruder for heating and conveying raw materials is fixedly mounted on the upper ends of both the first and second frames. A first forming module for processing corrugated pipes is movably mounted on the outer surface of the first electrically controlled conveyor belt, and a second forming module for processing corrugated pipes is movably mounted on the outer surface of the second electrically controlled conveyor belt. A horizontally placed guide box is fixedly mounted on the upper and lower ends of adjacent surfaces of the first and second frames. A connected cooling device is fixedly mounted inside the first and second frames below the horizontal extruder.

[0005] The horizontal extruder is equipped with a slanted discharge pipe that is connected to the interior of the horizontally placed guide box at the upper end of the first and second frames.

[0006] The lower surface of the horizontal guide box at the upper end of the first frame and the second frame, and the upper surface of the horizontal guide box at the lower end of the first frame and the second frame are all provided with strip-shaped guide grooves. The inside of the strip-shaped guide grooves is provided with a discharge port that communicates with the inside of the horizontal guide box.

[0007] The first molding module and the second molding module have arc-shaped molding grooves on their inner arc surfaces, and the first molding module and the second molding module have upper feeding channels that communicate with the inside of the arc-shaped molding grooves on their upper surfaces.

[0008] The first molding module and the second molding module have internal cooling channels located around the arc-shaped molding groove. The first molding module and the second molding module have lateral transition ports connected to the internal cooling channels on their assembly surfaces. The first molding module and the second molding module have bottom drain holes connected to the internal cooling channels on their lower surfaces.

[0009] Both the first molding module and the second molding module have outwardly protruding guide sealing covers at their upper and lower ends that cooperate with the strip-shaped guide grooves.

[0010] The cooling device includes a first cooling water tank fixed inside a first frame, a second cooling water tank fixed inside a second frame, a circulating water pump fixed inside the first cooling water tank, and a connecting pipe fixed between the first cooling water tank and the second cooling water tank.

[0011] The horizontal guide box at the lower end of the first frame and the first cooling water tank are both fixedly connected by inclined drain pipes.

[0012] The discharge ports at the upper and lower ends of the horizontally placed guide box are staggered.

[0013] The upper surface of the connecting pipe is fixedly fitted with a bottom-mounted anti-leakage funnel with an upper opening at the splicing end of the first forming module and the second forming module.

[0014] The beneficial effects of this invention are:

[0015] (1) The extrusion molding equipment for corrugated pipe production and processing of the present invention integrates the first electrically controlled conveyor belt, the second electrically controlled conveyor belt, the horizontal extruder and the cooling device inside the first frame and the second frame. The structure is compact, the space layout is more reasonable and the area occupied is small.

[0016] (2) The extruder and cooling device can be directly connected to the first forming module and the second forming module through the horizontal guide boxes on the adjacent surfaces of the first frame and the second frame. There is no need for a long-stroke material conveying operation, which can avoid energy loss and reduce the energy consumption of the horizontal extruder.

[0017] (3) By adopting the method of top feeding and bottom liquid feeding, the feeding and liquid feeding are staggered and will not affect each other, thus improving extrusion and cooling efficiency;

[0018] (4) By adopting synchronous material feeding, forming, cooling and separation operations during operation, the processing efficiency is greatly improved;

[0019] (5) By having guide sealing covers that protrude toward the strip guide groove at both the upper and lower ends of the first molding module and the second molding module, not only can the guiding properties of the first molding module and the second molding module be improved, but also the sealing properties and stability during the material guiding process can be improved.
