DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the utility model proposes a rapid prototyping mold structure for automobile injection molding parts, comprising:

[0021] A base 1, four support rods 2 are fixed on the base 1, and a support plate 16 is fixed on the upper ends of the four support rods 2. A lower mold 3 is installed on the base 1, and an upper mold 5 that can be raised and lowered is provided above the lower mold 3. Two hydraulic cylinders 4 are fixed on the support plate 16, and the output end of the hydraulic cylinder 4 is fixedly connected to the upper end of the upper mold 5;

[0022] A cooling assembly capable of cooling the lower mold 3 and the upper mold 5 at the same time; the cooling assembly includes a serpentine heat exchange flow channel 17 arranged in the lower mold 3 and the upper mold 5, the two serpentine heat exchange flow channels 17 are connected by a connecting pipe 15, a water tank 10 is installed on the support plate 16, a water pump 12 is installed on the water tank 10, a short pipe is installed at the water inlet end of the water pump 12, and the short pipe is connected to the water tank 10;

[0023] The water outlet of the water pump 12 is connected to the serpentine heat exchange channel 17 in the upper mold 5 through the water outlet pipe 13, and the other end of the serpentine heat exchange channel 17 in the lower mold 3 is connected to the water tank 10 through the return pipe 14. A semiconductor refrigeration sheet 11 is installed on the water tank 10. A radiator is installed on the upper end of the semiconductor refrigeration sheet 11 to dissipate heat from the semiconductor refrigeration sheet 11 to ensure its stable operation. The semiconductor refrigeration sheet 11 is used to cool the water in the water tank 10, so as to better cool the upper mold 5 and the lower mold 3.

[0024] When in use, the water pump 12 can work to transport the cooling water in the water tank 10 to the serpentine heat exchange flow channel 17 through the water outlet pipe 13. When the cooling water fills the serpentine heat exchange flow channel 17, the cooling water is transported to the serpentine heat exchange flow channel 17 in the lower mold 3 through the connecting pipe 15. When the serpentine heat exchange flow channel 17 in the lower mold 3 is filled with cooling water, it will flow back to the water tank 10 through the return pipe 14, thereby realizing the circulation of cooling water;

[0025] The upper mold 5 is provided with an injection flow channel. After the injection molding is completed, the water pump 12 is started to cool the upper mold 5 and the lower mold 3 at the same time, which can help the rapid molding of the injection molded parts and ensure the quality and efficiency of the molding; the semiconductor cooling plate 11 is provided to cool the circulating water, so that it can be recycled to ensure the quality of heat exchange and cooling;

[0026] When the upper mold 5 moves upward, the water pump 12 stops working, and the cooling water in the serpentine heat exchange channel 17 is heated by heat exchange, so that the heated cooling water no longer flows and will not affect the next injection molding work;

[0027] In addition, it also includes a limiting mechanism for limiting the connection pipe 15 and the water outlet pipe 13, the limiting mechanism includes a horizontal plate 6 fixed on the base 1, a vertical plate 7 is fixed on the upper end of the horizontal plate 6, two elastic ropes 8 are fixed on the vertical plate 7, and a pull ring 9 is fixed on the elastic rope 8. The pull ring 9 is set on the outside of the connection pipe 15 and the water outlet pipe 13;

[0028] Since the connecting pipe 15 and the water outlet pipe 13 are both hoses, when the upper mold 5 moves downward, the connecting pipe 15 and the water outlet pipe 13 will bend. In order to avoid moving between the upper mold 5 and the lower mold 3, the pull ring 9, the connecting pipe 15 and the water outlet pipe 13 can be pulled toward the vertical plate under the action of the elastic rope 8, thereby ensuring that the entire injection molding work is carried out stably.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
