[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5The utility model provides a technical solution: an MPP pipe extrusion molding die, comprising: a molding die body 1, a cooling box 2, a box door 3, an observation mirror 4, an MPP pipe channel 5, a filter screen 6, a hollow plate 7, a spray head 8, a water outlet pipe 9, a water pump 10, a water inlet pipe 11, a water tank 12, a partition plate 13, a serpentine pipe 14, a refrigeration device 15, a connecting frame 16, a motor 17, a gear 18 and a crawler 19;

[0029] When using the MPP tube extrusion die, Figure 3 and Figure 4 As shown, low-temperature cold water is stored in the water tank 12, and the partition plate 13 divides the water tank 12 into two parts. A one-way valve is provided on the lower side of the partition plate 13 to control the flow direction of the water in the water tank 12 and prevent the water in the water tank 12 from flowing from one side to the side where the serpentine pipe 14 is provided. In addition, a one-way valve is provided at the connection between the cooling box 2 and the water tank 12 to prevent the water in the water tank 12 from flowing to the lower side of the cooling box 2.

[0030] like Figure 1 , Figure 2 and Figure 5 As shown, when the forming die body 1 is started, the added raw materials will be extruded into MPP pipes, and then transported to the right side of the cooling box 2. MPP pipe channels 5 are arranged on the left and right sides of the cooling box 2. The extruded MPP pipes have a certain hardness, and the water sprayed by the spray head 8 will not deform the MPP pipes. When the water pump 10 is started, the water pump 10 will pump the cold water in the water tank 12 to the water outlet pipe 9 through the water inlet pipe 11, and then transport it to the hollow plate 7, and then evenly transport it to the spray head 8. The spray head 8 is distributed in an array on the lower side of the hollow plate 7, which increases the spraying area, thereby facilitating the cooling of the transported MPP pipes and facilitating subsequent transportation and cutting.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the interior of the cooling box 2 is provided with a filter 6, which can filter the cooled water to remove the impurities contained therein, and then deposit them on the lower side of the cooling box 2. The impurities adsorbed on the filter 6 can be observed from the observation mirror 4 in the box door 3 on the front side of the cooling box 2 to prevent the filter 6 from being blocked by too many impurities and affecting the discharge of the water flow. When it is found that there are too many impurities on the filter 6, the lock on the right front side of the box door 3 is opened, and the box door 3 is turned to open, and the filter 6 can be cleaned. When the water pump 10 is working, it will pump water from the water tank 12. In order to balance the air pressure, the water tank 12 will pump water filtered by the filter 6 from the cooling box 2. The pumped water will contact the serpentine pipe 14, and the refrigeration device 15 will be started. The refrigeration device 15 will cool the serpentine pipe 14. The serpentine pipe 14 can cool the water to lower its temperature, and then transport it to the other side of the partition plate 13, so as to achieve the purpose of recycling.

[0032] like Figure 1 and Figure 3 As shown, a motor 17 is provided on the right rear side of the connecting frame 16, and the motor 17 is fixedly connected to the gear 18 on the corresponding rear side. When the motor 17 is started, the motor 17 will rotate together with the gear 18. Since the gear 18 is meshed and connected with the track 19, the rotation of the gear 18 will cause the track 19 to transmit. The MPP pipe transported from the left side of the cooling box 2 will fit tightly with the lower side of the upper track 19, and will also fit tightly with the upper side of the lower track 19, thereby facilitating the transportation of the MPP pipe.
