[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a high-precision plastic mold that can be rapidly cooled. This provides the advantage of rapid cooling and solves the problems of low cooling efficiency in existing high-precision plastic molds during actual production. The inability of the mold to cool quickly leads to a longer molding cycle for each product, which severely restricts the overall production efficiency. Furthermore, the slow cooling process can easily cause quality problems such as product deformation and dimensional accuracy deviations, thus reducing the effectiveness of the high-precision plastic mold.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-precision plastic mold capable of rapid cooling, comprising a lower mold body, an upper mold body, a worktable, and a pressing device. The lower mold body is mounted on the top of the worktable, the pressing device is mounted on the top of the worktable, and the upper mold body is mounted on the bottom of the pressing device.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model achieves rapid cooling of the lower mold body and upper mold body of a high-precision plastic mold by setting a unidirectional heat dissipation component in conjunction with a heat conduction and heat dissipation component. This solves the problem of low cooling efficiency of existing high-precision plastic molds in actual production. Due to the inability of the mold to cool down quickly, the molding cycle of each molded product is extended, which seriously restricts the overall production efficiency. Moreover, the slow cooling process can easily lead to quality problems such as product deformation and dimensional accuracy deviation, which reduces the performance of high-precision plastic molds. This invention achieves the effect of rapid cooling.

[0017] 2. This utility model, by setting up a unidirectional heat dissipation component, utilizes the excellent thermal conductivity of the graphene plate in the connecting groove to quickly transfer the heat inside the lower mold body of the high-precision plastic mold. Then, the heat is further conducted by the superconducting heat nanoplate on the outside, and then conducted to the heat dissipation fins through the graphene rod. The unidirectional heat dissipation characteristic allows the heat to be dissipated more efficiently in a specific direction, avoiding the accumulation of heat inside the mold and effectively accelerating the cooling speed of the lower mold body of the high-precision plastic mold.

[0018] 3. By setting up a heat-conducting and heat-dissipating component, the graphene heat dissipation fins in the mounting groove can quickly dissipate the heat of the upper mold body of the high-precision plastic mold. At the same time, the blower in the movable groove on the mounting plate at the rear of the worktable can accelerate the airflow, so that the hot air around the graphene heat dissipation fins is quickly carried away, which enhances the heat dissipation effect and ensures that the upper mold body of the high-precision plastic mold can also be cooled quickly.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 3 As shown, the present invention provides a high-precision plastic mold that can be rapidly cooled, including a lower mold body 1, an upper mold body 2, a worktable 3, and a pressing device 4. The lower mold body 1 is installed on the top of the worktable 3, the pressing device 4 is installed on the top of the worktable 3, the upper mold body 2 is installed at the bottom of the pressing device 4, a one-way heat dissipation component 5 is provided on the outer side of the lower mold body 1, and a heat conduction and heat dissipation component 6 is provided on the top of the upper mold body 2.

[0026] As a technical optimization of this utility model, by setting up a unidirectional heat dissipation component 5, the excellent thermal conductivity of the graphene plate 52 in the connecting groove 51 can quickly transfer the heat inside the lower mold body 1 of the high-precision plastic mold. Then, the heat is further conducted by the superconducting nanoplate 53 on the outside, and then conducted to the heat dissipation fins 55 through the graphene rod 54. The unidirectional heat dissipation characteristic makes the heat dissipate more efficiently in a specific direction, avoids the accumulation of heat inside the mold, and effectively accelerates the cooling speed of the lower mold body 1 of the high-precision plastic mold.

[0027] refer to Figure 2 The heat dissipation component 6 includes a mounting slot 61, inside which a graphene heat dissipation fin 62 is installed. A mounting plate 63 is installed on the rear side of the top of the workbench 3. A movable slot 64 is opened on the front of the mounting plate 63, inside which a blower 65 is installed.

[0028] As a technical optimization of this utility model, by setting the heat conduction and heat dissipation component 6, the graphene heat dissipation fins 62 in the mounting groove 61 can quickly dissipate the heat of the upper mold body 2 of the high-precision plastic mold. At the same time, the blower 65 in the movable groove 64 on the mounting plate 63 on the rear side of the worktable 3 can accelerate the air flow, so that the hot air around the graphene heat dissipation fins 62 is quickly carried away, which enhances the heat dissipation effect and ensures that the upper mold body 2 of the high-precision plastic mold can also be cooled quickly.

[0029] refer to Figure 2 A fixing groove 7 is provided on the outer side of the front of the mounting plate 63. A cooling fan 8 is installed inside the fixing groove 7. A central pipe 9 is installed on the front of the cooling fan 8.

[0030] As a technical optimization of this utility model, by setting a fixed groove 7, a cooling fan 8 and a central pipe 9, the cooling fan 8 is installed in the fixed groove 7, which can draw out the hot air in the insulation box 11 and discharge it through the central pipe 9. This optimizes the direction of the heat dissipation airflow, enhances the heat dissipation effect on the lower mold body 1 of the high-precision plastic mold, further improves the cooling efficiency, and makes the mold cool more uniformly.

[0031] refer to Figure 3 A graphene sheet 10 is mounted on the outside of the graphene rod 54. Several graphene sheets 10 are arranged at equal intervals.

[0032] As a technical optimization of this utility model, by setting up graphene sheets 10, which are installed on the outside of graphene rods 54 and arranged at equal distances, the heat dissipation area is increased, and more heat can be dissipated to the surrounding environment through the graphene sheets 10, thereby improving the speed and efficiency of heat dissipation.

[0033] refer to Figure 3 An insulated box 11 is installed on the outer side of the top of the workbench 3. The heat dissipation fins 55, graphene rods 54, and graphene sheets 10 are located inside the insulated box 11. The back of the insulated box 11 is connected to the central pipe 9.

[0034] As a technical optimization of this utility model, by setting up an insulated box 11, the heat dissipation fins 55, graphene rods 54, graphene sheets 10, etc. are surrounded inside. On the one hand, the heat dissipation process is relatively concentrated, improving the heat dissipation efficiency, and on the other hand, the influence of surrounding heat on heat dissipation is reduced.

[0035] refer to Figure 2 An exhaust pipe 12 is installed on the front of the insulated box 11, and a filter plate 13 is installed on the back of the cooling fan 8.

[0036] As a technical optimization of this utility model, by setting an exhaust pipe 12 and a filter plate 13, the exhaust pipe 12 is installed on the front of the insulation box 11 to exhaust hot air and maintain the temperature balance inside the insulation box 11. The filter plate 13 is installed on the back of the cooling fan 8 to prevent dust and other impurities from entering the insulation box 11 and avoid impurities from affecting the heat dissipation effect.

[0037] refer to Figure 2 A temperature sensor 14 is mounted on the back of the mounting plate 63. The temperature sensor 14 is electrically connected to a controller 15 via a wire. The controller 15 is mounted on the top of the workbench 3. The controller 15 is electrically connected to an alarm 16 via a wire. The alarm 16 is mounted on the top of the workbench 3.

[0038] As a technical optimization of this utility model, a temperature sensor 14, a controller 15, and an alarm 16 are set up. The temperature sensor 14 is installed on the back of the mounting plate 63 to monitor the ambient temperature in real time and transmit the signal to the controller 15 to avoid the air temperature drawn in by the cooling fan and blower 65 being too high. When the temperature sensor 14 detects that the temperature is too high, it can send a signal to the controller 15. The controller 15 can then activate the alarm 16 to warn the user that the high temperature of the incoming air will affect the heat dissipation.

[0039] The working principle and usage process of this utility model are as follows: After the plastic material is injected into the mold cavity, the mold begins to heat up. The heat inside the lower mold body 1 of the high-precision plastic mold is first transferred to the graphene plate 52 in the connecting groove 51. Due to the excellent thermal conductivity of the graphene plate 52, the heat is quickly conducted through the graphene plate 52 to the superconducting nanoplate 53 on the outside. The superconducting nanoplate 53 further assists in heat conduction, transferring the heat to the graphene rod 54. The graphene rod 54 then conducts the heat to the heat dissipation fins 55 on its outside. At the same time, the graphene sheets 10 evenly spaced on the outside of the graphene rod 54 increase the heat dissipation area, allowing more heat to be dissipated. When the heat is released into the surrounding environment, the unidirectional heat dissipation characteristics of the unidirectional heat dissipation component 5 ensure that the heat is efficiently dissipated in a specific direction, avoiding accumulation inside the mold, thereby accelerating the cooling speed of the lower mold body 1 of the high-precision plastic mold. The heat of the upper mold body 2 of the high-precision plastic mold is transferred to the graphene heat dissipation fins 62 in the top mounting groove 61. The blower 65 in the front movable groove 64 of the mounting plate 63 on the rear side of the worktable 3 is started, accelerating the air flow. The rapidly flowing air quickly carries away the hot air around the graphene heat dissipation fins 62, enhancing the heat dissipation effect of the upper mold body 2 of the high-precision plastic mold and achieving rapid cooling of the upper mold body 2 of the high-precision plastic mold.

[0040] The cooling fan 8, installed in the mounting slot 7 on the front of the mounting plate 63, starts working, drawing hot air out of the insulation box 11. The hot air is then discharged through the central pipe 9. This process optimizes the airflow direction, enhances the overall heat dissipation of the mold, and makes the mold cool more evenly, further improving cooling efficiency. The insulation box 11, installed on the outer side of the top of the workbench 3, surrounds the heat dissipation fins 55, graphene rods 54, graphene sheets 10, etc. On the one hand, the insulation box 11 makes the heat dissipation process relatively concentrated, improving heat dissipation efficiency; on the other hand, it reduces the influence of ambient temperature on the heat dissipation environment, achieving rapid cooling and enhancing the performance of the high-precision plastic mold.

[0041] In summary, this high-precision plastic mold with rapid cooling solves the problems of low cooling efficiency in existing high-precision plastic molds during actual production. The mold's inability to cool quickly results in prolonged molding cycles for each molded product, severely restricting overall production efficiency. Furthermore, the slow cooling process can easily lead to product deformation, dimensional inaccuracies, and other quality issues, reducing the effectiveness of the high-precision plastic mold.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
