Description

Technical Field

[0001] This invention relates to the field of injection molds, specifically to an injection mold cooling system. Background Technology

[0002] Existing molds include cavities and cores installed within the cavities. During operation, the molds need to be cooled. The main method for cooling existing molds is to install multiple water channels inside the mold and cool the cavity walls, cavities, and cores by water cooling.

[0003] Currently, the cooling system of injection molds is often a water-well baffle structure, which mainly consists of a cooling water device connected to a water circulation loop on the mold. The existing injection mold cooling system is not fast enough in terms of cooling speed, and its work efficiency cannot be improved. It cannot meet the requirements of efficient cooling of injection molds, resulting in high production costs and increased workload for workers. Therefore, in view of the above situation, there is an urgent need to develop an injection mold cooling system to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide a cooling system for injection molds to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cooling system for an injection mold includes: a base; a lower mold base fixedly connected to the base; an upper mold platen disposed outside the lower mold base, opposite to the lower mold base, and connected to the base via a telescopic member; a cooling mechanism disposed between the lower mold base and the upper mold platen, used to cooperate with the lower mold base and the upper mold platen to cool the injection molded part; and an air blowing assembly connected to the upper mold platen and the cooling mechanism, used to cooperate with the cooling mechanism to achieve air flow; wherein the cooling mechanism includes: a liquid guiding assembly disposed inside the lower mold base, used to drive the flow of coolant; a heat absorption assembly disposed inside the upper mold platen and connected to the liquid guiding assembly, used to cooperate with the liquid guiding assembly to achieve the circulation of coolant; and a transmission assembly disposed between the heat absorption assembly and the air blowing assembly, used to cooperate with the flow of coolant to drive the air blowing assembly.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] During operation, the telescopic component drives the upper mold plate to rise and fall. The upper mold plate is connected to the lower mold base. The molten plastic enters the inner side of the lower mold base along the injection tube. After the injection molded part is formed, the liquid guiding component delivers coolant. During the flow of the coolant inside the liquid guiding component, it absorbs heat from the lower mold base. The liquid guiding component then delivers coolant into the heat absorption component. The heat absorption component, in conjunction with the upper mold plate, cools the top of the injection molded part. The coolant discharged from the heat absorption component flows back to the inner side of the liquid guiding component, where it is cooled again, thus continuously cooling the injection molded part. During the flow of the coolant inside the heat absorption component, it also drives the air blowing unit. The air blowing component drives the air around the lower mold base and upper mold platen to flow, thereby improving the cooling efficiency of the equipment. Compared with the existing injection mold cooling system, the cooling speed is not fast enough, the work efficiency is not improved, it cannot meet the high-efficiency cooling requirements of injection molds, the production cost is high, and the workload of workers is increased. By setting up a cooling mechanism in conjunction with the air blowing component, not only can the lower mold base and upper mold platen be cooled quickly and comprehensively, but the air flow can also be realized to further improve the cooling speed, improve the work efficiency, and meet the high-efficiency cooling requirements of injection molds.

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0016] Please see Figure 1 In one embodiment of the present invention, an injection mold cooling system includes: a base 1; a lower mold base 2, the lower mold base 2 being fixedly connected to the base 1; an upper mold plate 7, the upper mold plate 7 being disposed outside the lower mold base 2, opposite to the lower mold base 2, and connected to the base 1 via a telescopic member 8; a cooling mechanism, the cooling mechanism being disposed between the lower mold base 2 and the upper mold plate 7, for cooperating with the lower mold base 2 and the upper mold plate 7 to cool the injection molded part; and an air blowing assembly, the air blowing assembly being connected to the upper mold plate 7 and the cooling mechanism, for cooperating with the cooling mechanism to achieve air flow; wherein, the cooling mechanism includes: a liquid guiding assembly, the liquid guiding assembly being disposed inside the lower mold base 2, for driving the flow of coolant; a heat absorption assembly, the heat absorption assembly being disposed inside the upper mold plate 7 and connected to the liquid guiding assembly, for cooperating with the liquid guiding assembly to achieve the circulation flow of coolant; and a transmission assembly, the transmission assembly being disposed between the heat absorption assembly and the air blowing assembly, for cooperating with the flow of coolant to drive the air blowing assembly.

[0017] In this embodiment, the telescopic components 8 are symmetrically arranged on both sides of the lower mold base 2, with one end fixedly connected to the base 1 and the other end fixedly connected to the upper mold plate 7. The telescopic components 8 are electric telescopic rods. Additionally, an injection tube 11 for inputting molten plastic is fixedly connected to the upper mold plate 7. A valve, a solenoid valve, is fixedly connected to the inner side of the injection tube 11. When the device is running, the telescopic components 8 drive the upper mold plate 7 to rise and fall. The upper mold plate 7 is connected to the lower mold base 2, and the molten plastic enters the inner side of the lower mold base 2 along the injection tube 11. After the injection molded part is formed, the liquid guiding component delivers coolant. During the flow of the coolant within the liquid guiding component, it absorbs heat from the lower mold base 2. The liquid guiding component then delivers coolant into the heat absorption component, which, in conjunction with the upper mold plate 7, cools the top of the injection molded part. The coolant discharged from the heat-absorbing component flows back to the inside of the liquid-guiding component, where it is cooled, thus continuously cooling the injection molded part. During the flow of the coolant inside the heat-absorbing component, it also drives the air-blowing component, which in turn drives the air around the lower mold base 2 and the upper mold plate 7 to circulate, thereby improving the cooling efficiency of the equipment. Compared to existing injection mold cooling systems, the cooling speed is not fast enough, resulting in lower work efficiency and failing to meet the high-efficiency cooling requirements of injection molds. This leads to higher production costs and increased workload for workers. By setting up a cooling mechanism in conjunction with the air-blowing component, not only can the lower mold base 2 and the upper mold plate 7 be cooled quickly and comprehensively, but airflow is also achieved, further increasing the cooling speed, improving work efficiency, and meeting the high-efficiency cooling requirements of injection molds.

The water pump 4 drives the coolant into the inner side of the water guide pipe 5 and into the inner side of the heat absorption component along the water guide pipe 5. During the flow of the coolant inside the water guide pipe 5, it can cooperate with the lower mold base 2 to cool the injection molded part. The coolant discharged from the heat absorption component flows back to the inner side of the heat exchanger 14 along the fixed pipe 13.
