Detailed Implementation

[0027] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0028] Please see Figure 1This utility model provides an injection mold with good heat dissipation performance, including a base plate 1, a support plate 2 at the upper rear side of the base plate 1, a cylinder 3 installed at the front side of the support plate 2, the lower end of the cylinder 3 being connected to an upper mold 4, an injection port 5 at the middle of the upper end of the upper mold 4, and positioning shafts 6 at the four corners of the bottom of the upper mold 4, a lower mold 7 opposite to the lower end of the upper mold 4, a mold groove 8 inside the lower mold 7, and the lower end of the lower mold 7 being connected to a base 9, the base 9 being connected to the upper end of the base plate 1, and a heat dissipation device 10 disposed inside the base 9.

[0029] Please see Figure 2 In this embodiment, the heat dissipation device 10 includes a water storage tank 101 inside the base plate 1 for collecting and recycling water, drain outlets 102 symmetrically opened on the left and right sides inside the water storage tank 101, drain pipes 103 connected to the outer ends of the drain outlets 102 on both sides, a heat dissipation component 104 connected to the bottom of the lower mold 7 and vertically opposite to the water storage tank 101, which can accelerate the injection molding efficiency of the model through the heat conduction effect of the heat dissipation component 104, and a spraying component 105 connected to the outside of the heat dissipation component 104 for spraying and cooling the heat dissipation component 104.

[0030] Please see Figure 3 In this embodiment, the heat sink 104 includes a connecting frame 1041 connected to the bottom of the lower mold 7 for connection, a heat sink copper plate 1042 installed inside the connecting frame 1041 for heat conduction and heat dissipation, and heat sink fins 1043 equidistantly installed at the lower end of the heat sink copper plate 1042 to achieve heat conduction and heat dissipation.

[0031] The heat dissipation fins 1043 are equidistantly installed on both sides of the lower end of the heat dissipation copper plate 1042, and there is a gap between the bottom of the heat dissipation fins 1043 and the water storage tank 101, so as to ensure that when the heat dissipation fins 1043 are sprayed for cooling, the cooling water can flow into the water storage tank 101 after use, so as to realize the recycling and reuse activities.

[0032] Please see Figures 4-8In this embodiment, the spraying assembly 105 includes a support frame 1051 fastened to the upper right side of the base plate 1 for support and guidance, a side plate 1052 fixedly connected to the right side of the support frame 1051, a movable structure 1053 installed in the middle of the upper end of the side plate 1052 for vertical movement, a main water pipe 1054 connected to the upper end of the movable structure 1053, and an integral water inlet end in the middle of the upper end of the main water pipe 1054 for quick connection with an external water pipe, connecting blocks 1055 symmetrically rotated and connected to both ends of the main water pipe 1054, guide grooves 1056 symmetrically opened on the front and rear sides of the upper end of the support frame 1051 and connected to the outer sides of the connecting blocks 1055 on both sides, thereby forming a vertical movement guide state to ensure smoothness and stability of subsequent reciprocating lifting process, an auxiliary water pipe 1057 equidistantly installed on the left side of the main water pipe 1054, and nozzles 1058 symmetrically installed on both sides of the outer end of the auxiliary water pipe 1057.

[0033] The movable structure 1053 includes a first bracket 10531 fastened to the middle of the upper end of the side plate 1052, a motor 10532 connected to the lower end of the first bracket 10531, a rotating drum 10533 connected to the upper end of the motor 10532 and vertically mounted on the upper end of the first bracket 10531, a second bracket 10534 fixedly connected to the right side of the upper end of the first bracket 10531 and connected to the upper end of the rotating drum 10533, thereby ensuring the stability of the rotating drum 10533 during rotation, a transmission groove 10535 correspondingly opened on the outside of the rotating drum 10533, a connecting frame 10536 connected to the outside of the upper end of the rotating drum 10533 and connected to the middle of the main water pipe 1054, and a connecting shaft 10537 fastened to the right side inside the connecting frame 10536 and connected to the inside of the transmission groove 10535.

[0034] The support frame 1051 has long strips on both sides at the top, and a main water pipe 1054 is installed between the long strips on both sides of the top of the support frame 1051 to ensure that the support frame 1051 can stably move the main water pipe 1054 up and down. The auxiliary water pipe 1057 is inserted between adjacent heat dissipation fins 1043, and the nozzles 1058 on both sides of the outer end of the auxiliary water pipe 1057 are opposite to the sides of the heat dissipation fins 1043 to ensure that the auxiliary water pipe 1057 can efficiently spray and cool the adjacent heat dissipation fins 1043, so as to ensure the efficient heat dissipation effect of the heat dissipation fins 1043.

[0035] The transmission groove 10535 is formed into a circulating groove, and the upper right side of the transmission groove 10535 is connected to the connecting shaft 10537 inside the connecting frame 10536, so that the transmission groove 10535 can cooperate with the connecting shaft 10537 through its own circulating state, so that the connecting shaft 10537 can move up and down stably.

[0036] The working principle is as follows:

[0037] When performing injection molding of the model, the cylinder 3 located at the upper front of the support plate 2 can be driven to push the upper mold 4 downwards. As the upper mold 4 moves downwards, it moves towards the lower mold 7 to abut against the upper end of the lower mold 7. At the same time, with the positioning and insertion effect of the positioning shafts 6 on the four sides of the bottom of the upper mold 4, the accurate abutment and docking of the upper mold 4 and the lower mold 7 can be ensured. In this way, the mold groove 8 opened inside the lower mold 7 can be closed. At this time, the material can be injected through the injection port 5 at the upper end of the upper mold 4 to fill the mold groove 8. After injection molding, the material inside the mold groove 8 can be solidified and molded after a period of cooling. At this time, by closing the cylinder 3, the upper mold 4 is moved upwards, so that the upper mold 4 can quickly release the abutment and sealing effect with the lower mold 7. In this way, the product molded inside the mold groove 8 can be easily removed. Thus, through such repeated operation, the product injection molding process can be achieved.

[0038] When the material is cooled and solidified inside the mold groove 8, in order to accelerate its molding efficiency, a heat dissipation component 104 is provided at the lower end of the lower mold 7. First, the heat dissipation copper plate 1042 installed inside the connecting frame 1041 will be connected to the bottom of the mold groove 8. In this way, the heat generated by the material can be dissipated externally. At the same time, with the heat dissipation fins 1043 arranged at multiple equidistant points at the bottom of the heat dissipation copper plate 1042, the heat dissipation effect can be further enhanced. In this way, the material undergoing static solidification and molding inside the mold groove 8 can undergo efficient heat dissipation and cooling, and accelerate the injection molding efficiency of the product.

[0039] To ensure that the heat dissipation fins 1043 remain cooled for an extended period during auxiliary heat dissipation activities, the main water pipe 1054 inside the spray assembly 105 is connected to an external water pipe via a water inlet located at the upper center. Cold water then enters the main water pipe 1054 through the inlet and flows into multiple auxiliary water pipes 1057 connected to one side. Since the auxiliary water pipes 1057 are installed between adjacent heat dissipation fins 1043 and have nozzles 1058 on both sides, cold water can efficiently spray and cool the sides of the heat dissipation fins 1043 along the nozzles, maintaining a cooled state for a longer period and ensuring efficient heat dissipation. To further enhance the cooling effect on the exterior of the heat dissipation fins 1043, a motor 10 at the lower end of the first bracket 10531 can be used. 532, the motor 10532 is connected to the upper end of the rotating drum 10533 to rotate. As the rotating drum 10533 rotates, the connecting frame 10536 connected to the outer side of the upper end of the rotating drum 10533 will be connected to the transmission groove 10535 on the outer side of the rotating drum 10533 through the connecting shaft 10537 opened on the inner right side. This will cause the connecting frame 10536 to move up and down reciprocally as a whole. At the same time, during the up and down reciprocating movement of the main water pipe 1054, the connecting blocks 1055 on the front and rear sides and the guide grooves 1056 opened on the front and rear sides of the upper end of the support frame 1051 can be connected to achieve stable up and down reciprocating movement. As the main water pipe 1054 moves up and down, multiple auxiliary water pipes 1057 connected to one side of the main water pipe 1054 will move up and down synchronously to efficiently achieve spray cooling on the outer side of the heat dissipation fins 1043, greatly enhancing its heat dissipation effect.

[0040] When cold water is sprayed onto the outside of the heat dissipation fins 1043 and flows down along the outside of the heat dissipation fins 1043, it will collect in the water storage tank 101 opened inside the upper end of the base plate 1. With the drainage outlets 102 provided on both sides inside the water storage tank 101, the recycled water can be recycled back to the inside of the external equipment through the drainage pipe 103 provided at the outer end, so as to recycle and reuse the cold water and ensure the conservation of resources.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
