Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0024] Example 1

[0025] See also Figure 1-Figure 5 A material discharge device for a blow molding machine comprises a support frame 1, and a non-slip pad 22 is arranged on the support foot of the support frame 1. When the device is in operation, it performs shock absorption and anti-slip operations. A discharge barrel 2 in the shape of a funnel is installed in the middle position of the upper part of the support frame 1. The design of this shape is convenient for centralized material discharge. A servo motor 3 is installed on the discharge barrel 2. The output shaft of the servo motor 3 is connected with a stirring rod 4. The stirring rod 4 is located inside the discharge barrel 2. The servo motor 3 can drive the stirring rod 4 to stir the plastic particles so that the plastic particles are evenly heated. A heating cylinder 5 is sheathed on the outside of the discharge barrel 2. Two transparent glasses 6 symmetrically distributed front and back are embedded in the lower part of the discharge barrel 2. The internal situation of the discharge barrel 2 can be observed through the transparent glass 6. A storage barrel 7 is installed on the support frame 1. The material storage barrel 7 is located below the material discharge barrel 2, and the material storage barrel 7 is communicated with the material discharge barrel 2. Two molds 8 symmetrically distributed on the left and right are installed at the lower part of the support frame 1. The mold 8 is located below the material storage barrel 7. A double-axis motor 9 is installed at the lower part of the support frame 1. Both ends of the double-axis motor 9 are connected with a bidirectional threaded rod 10 through a key. The bidirectional threaded rod 10 is threadedly connected to the mold 8. The operation of the double-axis motor 9 can drive the bidirectional threaded rod 10 to rotate, thereby driving the two molds 8 to open and close. A guide rod 11 is provided in the support frame 1, and the mold 8 can slide laterally on the guide rod 11. An air pump 12 is installed on the support frame 1, and the air pump 12 is located between the molds 8. A quantitative component is provided in the material storage barrel 7. The quantitative component.

[0026] See also Figure 4 and Figure 6 The quantitative component includes two fixing frames 13, and the two fixing frames 13 are fixed on the support frame 1. A driving motor 14 is installed on the top of the fixing frame 13 on the left side. A rotating shaft 15 is rotated through the middle of the storage barrel 7, and the left end of the rotating shaft 15 is connected to the output shaft of the driving motor 14. An intelligent quantitative barrel 16 is arranged on the rotating shaft 15. The intelligent quantitative barrel 16 can measure the plastic particles. The rotating shaft 15 is driven to rotate by the driving motor 14, so that the intelligent quantitative barrel 16 can be turned over for quantitative unloading. Two receiving plates 17 symmetrically distributed front and back are slidingly arranged in the intelligent quantitative barrel 16. The intelligent quantitative barrel 16 is provided with two receiving plates 17 for double-sided material receiving design, which can take over and unload materials back and forth to ensure continuous operation. A telescopic spring 18 is connected between the receiving plate 17 and the intelligent quantitative barrel 16.

[0027] First, add plastic particles into the discharge barrel 2, which are heated and melted by the heating cylinder 5. The melted plastic particles flow along the discharge barrel 2 into the storage barrel 7 and are received by the receiving plate 17 on the intelligent quantitative barrel 16 and weighed. When the received weight reaches the set weight, the driving motor 14 drives the intelligent quantitative barrel 16 to flip, and the receiving plate 17 extrude the plastic particles between the two molds 8 to achieve quantitative unloading. At the same time, the receiving plate 17 on the other side begins to receive the material to prepare for the production of the next product, ensuring continuous and efficient production. Subsequently, the blowing head of the blowing pump 12 rises to the limit, and then the dual-axis motor 9 drives the bidirectional threaded rod 10 to rotate forward to close the two molds 8. At this time, the blowing pump 12 starts to start blowing, and the high-pressure airflow is injected to stretch the plastic particles, so that the plastic particles are inflated and fit tightly on the inner wall of the mold 8 to form the desired shape of the hollow product.

[0028] Example 2

[0029] Based on Example 1, please refer to Figure 4 and Figure 5 A circulating water tank 19 is installed on the front side of the lower part of the mold 8, and a heat sink 21 is arranged on the side of the mold 8. The circulating water tank 19 is connected to an infusion tube 20, and the infusion tube 20 is arranged on the heat sink 21 in a serpentine shape to increase the contact area and facilitate heat dissipation.

[0030] After the product is manufactured, the coolant flows back and forth in the infusion tube 20 to take away the heat from the surface of the mold 8, and then dissipates the heat outward through the heat sink 21 to cool the mold 8, thereby accelerating the cooling speed of the product and helping the product to be demoulded quickly.
