Embodiment 1

[0025] A corrugated pipe forming machine, including two circulating closed chute 1, a number of sliding seats 8 are installed on the chute 1, and a mold is installed on each sliding seat 8, and the molds on the two chute 1 cooperate to form during the movement Bellows forming channel, cooling boxes 2 are provided on both sides of the chute 1 away from the bellows forming channel, and cooling fins 9 are connected to both sides of each mold, and the side of the cooling box 2 close to the mold is along the mold movement direction A first notch is opened, and a second notch is opened at both ends of the cooling box 2, and the first notch communicates with the second notch, so that when the mold moves, the heat sink 9 enters the cooling box 2 from the second notch at one end of the cooling box 2 Then move along the first notch, and pass through the second notch at the other end; the top of the cooling box 2 is provided with a spray pipe 10 connected to an external water source, and ...

Embodiment 2

[0028] Based on Embodiment 1, the nozzles 11 are arranged along the moving direction of the mould, which is beneficial for the cooling fins 9 to repeatedly contact with the cooling water when they move in the cooling box 2, so that the cooling fins 9 can quickly cool down and increase the heat between the mold and the cooling fins 9. The transmission efficiency ensures that the mold reaches a lower temperature and improves the cooling and shaping efficiency of the bellows.

Embodiment 3

[0030] Based on Embodiment 1, the heat sink 9 is provided with evenly distributed capillary holes, so that a large number of small water droplets remain on the water-cooled heat sink 9, and these small water droplets are heated and evaporated when the mold is working, absorbing the heat on the heat sink 9, and enhancing heat dissipation The heat dissipation effect of the sheet 9 further improves the cooling and shaping effect of the bellows.

Abstract

The invention discloses a corrugated pipe molding machine and a corrugated pipe production technology based on same. The corrugated pipe molding machine comprises two circular sealed sliding groove, molds which are moved on the sliding grooves cooperatively form a corrugated pipe molding passage, cooling boxes are arranged on the two sides, away from the corrugated pipe molding passage, of the sliding grooves, the two sides of each mold are connected with heat dissipating pieces, first gaps are formed in the sides, close to the molds, of the cooling boxes in the moving directions of the molds,second gaps are formed in the two ends of the cooling boxes, and the first gaps are communicated with the second gaps to allow the heat dissipating pieces to move towards the first gaps after entering the cooling boxes from the second gaps formed in one ends of the cooling boxes when the molds are moved and penetrate out from the second gaps formed in the other ends; the tops of the cooling boxesare provided with spraying pipes which are connected with an external water source, and nozzles which are uniformly distributed are arranged on the spraying pipes. According to the machine, the problem that water easily flows into the sliding grooves to cause equipment failures when the molds are directly cooled by water, the temperature of the molds which are cooled twice is lower, and the cooling molding efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of corrugated pipe forming equipment, and in particular relates to a corrugated pipe forming machine and a corrugated pipe production process based on the corrugated pipe forming machine. Background technique [0002] Plastic corrugated pipe products are beautiful, light and durable, and are relatively mature in terms of equipment, molding technology, process, and raw materials. The material has gradually expanded from PVC to PE, PP and other raw materials, and the pipe diameter has gradually developed in the direction of larger diameters. When manufacturing plastic bellows, the raw material is first heated to a molten state, then the molten plastic is extruded into a tube blank, and then the tube blank is sent into a forming mold for molding, and then cooled and shaped in the forming mold. [0003] Cooling is an important process in the production process of plastic bellows, and the cooling efficiency deter...
