[0003] Existing concave cam forming molds are all provided with cooling structures to speed up the forming speed of the concave cam. However, usually several cooling pipes are fixedly provided on the lower mold and the upper mold respectively. Since the lower mold and the upper mold are separated when not in use, the cooling pipes on the lower mold and the upper mold are also separated, and there is no connection between the cooling pipes of the lower mold and the upper mold. Therefore, when the lower mold and the upper mold are assembled and merged together, it is necessary to separately supply cooling water to the cooling pipes on the lower mold and the upper mold, which makes the cooling process more inconvenient, and the cooling effect is not ideal, which will affect the forming speed and demolding effect of the concave cam.

Implementation

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0022] Reference Figure 1-2 and Figure 4 A concave cam forming mold comprises a lower mold 1 and an upper mold 2, an injection tube 6 is fixedly connected to the upper mold 2, grooves 3 are respectively provided on the lower surface of the lower mold 1 and the upper surface of the upper mold 2, cooling tubes 4 are respectively provided in the two grooves 3, and the two cooling tubes 4 are both serpentine tubes. The serpentine tubes can make the cooling tubes 4 fully and comprehensively distributed in the corresponding grooves 3, thereby increasing the contact area between the lower mold 1 and the upper mold 2, and improving the cooling effect on the lower mold 1 and the upper mold 2.

[0023] The two cooling pipes 4 are fixed in the two grooves 3 by a plurality of fixing parts 5, and the plurality of fixing parts 5 are fixedly connected to the inner bottom of the two grooves 3, respectively. The plurality of fixing parts 5 adopt a clamp-type fixing structure, which facilitates the installation of the two cooling pipes 4 and improves the stability of the two cooling pipes 4 in the corresponding grooves 3.

[0024] A cover plate 7 is provided at the upper end of the groove 3 on the upper surface of the upper mold 2, and a through hole 8 is formed on the cover plate 7, and the injection tube 6 passes through the through hole 8. When the two cooling tubes 4 are installed and the lower mold 1 and the upper mold 2 are assembled and fixed, the cover plate 7 can be fixed at the upper end of the groove 3 on the upper surface of the upper mold 2, and the injection tube 6 passes through the through hole 8, which can not only protect the cooling tube 4 in the groove 3, but also prevent the excessive leakage of cold air in the groove 3 during cooling and affect its cooling effect. In addition, the added cover plate 7 will not affect the normal molten metal injection process through the injection tube 6.

[0025] One end of the cooling pipe 4 in the lower mold 1 is fixedly connected to a water inlet pipe 9, and the water inlet pipe 9 is externally connected to a cooling water supply mechanism. The other end of the cooling pipe 4 in the lower mold 1 is fixedly connected to a guide tube 10. One end of the cooling pipe 4 in the upper mold 2 is fixedly connected to a water outlet pipe 12. The other end of the cooling pipe 4 in the upper mold 2 is fixedly connected to a plug 11, and the plug 11 is connected to the plug 10. Through the cooling water supply mechanism, cooling water is transported to the cooling pipe 4 in the lower mold 1 through the water inlet pipe 9, and the cooling water will be distributed in the lower mold 1, and then the cooling water is transported to the cooling pipe 4 in the upper mold 2 through the guide tube 10 and the plug 11 in turn. The cooling water will be distributed in the upper mold 2, and then the cooling water flowing through the lower mold 1 and the upper mold 2 will eventually be discharged through the outlet pipe 12. Therefore, by adopting two cooling pipes 4 of serpentine pipes, the cooling water can fully contact the lower mold 1 and the upper mold 2, thereby effectively improving the cooling effect of the lower mold 1 and the upper mold 2; moreover, when assembling the lower mold 1 and the upper mold 2, it is necessary to insert the lower end of the insert 11 into the conduit 10 to connect the two, so that the cooling water can be supplied to the two cooling pipes 4 at the same time, and there is no need to supply cooling water to the two cooling pipes 4 separately, which makes the cooling process more convenient. Example

[0026] Reference Figure 1-3 As another preferred embodiment of the utility model, the difference from embodiment 1 is that a sealing mechanism is arranged between the catheter 10 and the cannula 11, and the sealing mechanism includes a sealing groove 17 and an airbag 18. The sealing groove 17 is opened on one side of the upper surface of the lower mold 1, and the airbag 18 is fixedly sleeved on the cannula 11, and the airbag 18 is located in the sealing groove 17.

[0027] The airbag 18 is fixedly connected with an inflation pipe 19 and an deflation pipe 21 , and both of the inflation pipe 19 and the deflation pipe 21 extend to one side of the upper mold 2 . One end of the inflation pipe 19 is fixedly connected with an air pump 20 , and one end of the deflation pipe 21 is fixedly connected with a pressure relief valve 22 .

[0028] When the lower end of the insert tube 11 is inserted into the conduit 10 to connect the two during the assembly of the lower mold 1 and the upper mold 2, the airbag 18 will eventually move into the sealing groove 17, and then the pressure relief valve 22 is closed, the air pump 20 is started, and the airbag 18 is inflated through the inflation tube 19 to expand it. When the airbag 18 expands to completely fill the sealing groove 17, the sealing groove 17 will be sealed, so that the insert tube 11 and the conduit 10 are completely sealed, thereby avoiding the leakage of cooling water between the insert tube 11 and the conduit 10 during the process of conveying cooling water; after the injection molding is completed, when the lower mold 1 and the upper mold 2 need to be disassembled for demolding, it is only necessary to open the pressure relief valve 22 and deflate the airbag 18 through the deflation tube 21 to directly move the airbag 18 out of the sealing groove 17. Therefore, by inflating the airbag 18 to expand it, the sealing groove 17 can be sealed, and then the cannula 11 and the catheter 10 can be easily sealed, avoiding the cooling water leakage between the cannula 11 and the catheter 10 during the process of conveying cooling water and affecting the cooling effect. Example

[0029] Reference Figure 1 As another preferred embodiment of the utility model, the difference from embodiment 1 is that the water inlet pipe 9 and the water outlet pipe 12 are connected through a water circulation mechanism, the water circulation mechanism includes a circulation pipe 13 and a water delivery pipe 14, the circulation pipe 13 is connected to one end of the water outlet pipe 12, the water delivery pipe 14 is connected to one end of the water inlet pipe 9, and one end of the water delivery pipe 14 is connected to a water pump 15, the water pump 15 is arranged in a water tank 16, and the water tank 16 is filled with cooling water. The cooling water discharged from the water outlet pipe 12 will directly flow into the water tank 16, and then, the cooling water can be supplied again through the water pump 15 and the water delivery pipe 14, thereby realizing the recycling of cooling water and avoiding waste.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
