Description

Technical Field

[0001] This utility model relates to the field of injection molds, and specifically to an injection mold with high-efficiency cooling. Background Technology

[0002] In the field of injection molding, the mold generates a large amount of heat during the injection process due to the melting, filling, and solidification of plastic raw materials. If this heat cannot be dissipated in a timely and effective manner, the mold temperature will become too high, which will affect the quality of the injection molded product, such as product deformation, inaccurate dimensions, and poor surface quality.

[0003] Existing injection mold cooling methods typically involve installing cooling channels inside the mold, with a cooling medium flowing through these channels to remove some heat. However, this traditional cooling method has significant shortcomings. Due to the relatively enclosed structure of the mold, heat around the cooling channels is difficult to dissipate quickly to the external environment. As the injection process continues, the temperature around the cooling channels gradually rises, leading to a decrease in cooling efficiency. This prevents the timely and sufficient removal of heat from the mold, resulting in persistently high mold temperatures. This not only affects product quality but also shortens the mold's lifespan.

[0004] Furthermore, existing injection molds have relatively simple heat dissipation structures and lack effective mechanisms to automatically adjust heat dissipation capacity based on changes in the mold's internal temperature. When the temperature around the cooling channels rises, measures cannot be taken in time to accelerate heat dissipation, making it difficult to adapt to the constantly changing heat dissipation requirements during the injection molding process. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned defects and provide an injection mold with high-efficiency cooling. This solves the technical problem that the existing technology is unable to quickly dissipate the heat inside the mold, resulting in slow mold cooling and reduced cooling effect.

[0006] The objective of this utility model is achieved through the following means:

[0007] A high-efficiency cooling injection mold includes an upper mold and a lower mold below the upper mold. Cooling pipes are installed inside both the upper and lower molds. A distributor is installed at the inlet of each cooling pipe, and a collector is installed at the outlet of each cooling pipe. Mounting frames are installed on the upper and lower sides of both the upper and lower molds. Adjusting plates are embedded inside each mounting frame. Heat dissipation fins are mounted between the adjusting plates on the same side via a rotating shaft. Adjusting blocks are installed on the upper and lower surfaces of each adjusting plate. Adjusting grooves are formed on the upper and lower surfaces of each heat dissipation fin, and the adjusting blocks are inserted into the corresponding adjusting grooves.

[0008] Furthermore, heat dissipation grooves are provided on the bottom of the upper mold and the upper surface of the lower mold. The heat dissipation grooves are located in the side walls of the upper mold and the lower mold, and heat dissipation treatment can be carried out at the connection between the upper mold and the lower mold through the heat dissipation grooves.

[0009] Furthermore, both the upper and lower molds have mounting chambers inside their side walls. These mounting chambers are U-shaped, and the cooling pipes are located inside the mounting chambers. The cooling pipes are installed along the inner walls of the mounting chambers, allowing for heat dissipation from the interior of the upper and lower molds.

[0010] Furthermore, each of the heat dissipation slots is equipped with a connecting plate, which communicates with the interior of the installation chamber, allowing the cold air from the cooling pipes to enter the heat dissipation slots.

[0011] Furthermore, fans are installed on the upper surface of the upper mold and the lower surface of the lower mold. The fans enable the air to circulate inside the upper and lower molds, thereby effectively cooling the upper and lower molds.

[0012] Furthermore, the surface of the adjustment plate is equipped with a sliding plate, and the inner wall of the mounting frame is provided with a groove corresponding to the sliding plate. The sliding plate is inserted into the groove, so that the adjustment plate can move in a straight line.

[0013] The beneficial effects of this invention are as follows: the highly efficient cooling injection mold cools the interior of the upper and lower molds through cooling pipes, and adjusts the size of the openings on the surfaces of the upper and lower molds by means of heat dissipation fins. When the temperature around the cooling pipes rises, the adjusting plate is moved so that the adjusting block moves along the adjusting groove, thereby opening the heat dissipation fins, expanding the openings on the surfaces of the upper and lower molds, and expelling the hot air around the cooling pipes, thereby accelerating heat dissipation and thus efficiently cooling the injection mold.

[0023] In this embodiment, refer to Figure 1 - Figure 7 The specific implementation of a high-efficiency cooling injection mold includes an upper mold 1, a lower mold 2 below the upper mold 1, cooling pipes 3 installed inside both the upper mold 1 and the lower mold 2, a distributor 4 installed at the inlet of the cooling pipes 3, a collector 5 installed at the outlet of the cooling pipes 3, mounting frames 6 installed on the upper and lower sides of both the upper mold 1 and the lower mold 2, adjusting plates 7 embedded inside the mounting frames 6, heat dissipation fins 8 installed between the adjusting plates 7 on the same side via a rotating shaft, adjusting blocks 9 installed on the upper and lower surfaces of the adjusting plates 7, adjusting grooves 10 opened on the upper and lower surfaces of the heat dissipation fins 8, and adjusting blocks 9 inserted into the corresponding side adjusting grooves 10;

[0024] The cooling pipe 3 can cool the interior of the upper mold 1 and the lower mold 2. The size of the opening on the surface of the upper mold 1 and the lower mold 2 can be adjusted by the heat dissipation fins 8. The upper mold 1 and the lower mold 2 can be cooled immediately when they are working. At the same time, when the temperature around the cooling pipe 3 rises, the adjusting plate 7 can be moved along the adjusting groove 10 by the adjusting block 9, thereby opening the heat dissipation fins 8, which can enlarge the opening on the surface of the upper mold 1 and the lower mold 2, and exhaust the hot air around the cooling pipe 3, accelerate the heat dissipation, and thus efficiently cool the injection mold.

[0025] Heat dissipation grooves 11 are provided on the bottom of the upper mold 1 and the upper surface of the lower mold 2. The heat dissipation grooves 11 are located in the side walls of the upper mold 1 and the lower mold 2. The heat dissipation grooves 11 can be used to dissipate heat at the connection between the upper mold 1 and the lower mold 2.

[0026] Both the upper mold 1 and the lower mold 2 have installation chambers inside their side walls. The installation chambers are all U-shaped. The cooling pipes 3 are located inside the installation chambers and are installed along the inner wall of the installation chambers. The cooling pipes 3 can dissipate heat from the interior of the upper mold 1 and the lower mold 2.

[0027] Each heat dissipation slot 11 is equipped with a connecting plate 12, which communicates with the interior of the installation chamber, allowing the cold air from the cooling pipe 3 to enter the heat dissipation slot 11.

[0028] Fans 13 are installed on the upper surface of the upper mold 1 and the lower surface of the lower mold 2. The fans 13 enable the air to circulate inside the upper mold 1 and the lower mold 2, thereby fully cooling the upper mold 1 and the lower mold 2.

[0029] The surface of the adjustment plate 7 is equipped with a sliding plate 14. The inner wall of the mounting frame 6 is provided with a groove 15 corresponding to the sliding plate 14. The sliding plate 14 is inserted into the groove 15, so that the adjustment plate 7 can move in a straight line.

[0030] The working process of a high-efficiency cooling injection mold in this embodiment is as follows: First, the cooling pipe 3 can cool the interior of the upper mold 1 and the lower mold 2. The size of the opening on the surface of the upper mold 1 and the lower mold 2 can be adjusted by the heat dissipation fins 8, thereby preventing a large amount of cold air from the cooling pipe 3 from escaping. The upper mold 1 and the lower mold 2 can be cooled immediately when they are working. Then, when the temperature around the cooling pipe 3 rises, the adjusting plate 7 can move along the adjusting groove 10 by the adjusting block 9, thereby opening the heat dissipation fins 8, which can enlarge the opening on the surface of the upper mold 1 and the lower mold 2, and discharge the hot air around the cooling pipe 3, accelerating heat dissipation, thereby efficiently cooling the injection mold. Finally, the connecting plate 12 is connected to the interior of the mounting chamber, so that the cold air from the cooling pipe 3 can enter the heat dissipation groove 11. The heat dissipation groove 11 can dissipate heat at the connection between the upper mold 1 and the lower mold 2. The fan 13 is started to allow the gas inside the upper mold 1 and the lower mold 2 to circulate with the outside, improving the heat dissipation effect of the mold.
