DETAILED DESCRIPTION

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3As shown, it is a structural diagram of a novel injection mold cooling device provided by an embodiment of the present invention, comprising a workbench 1, vertical rods 11 are fixedly installed on the surface of the workbench 1, a top plate 12 is fixedly installed on the top of multiple groups of vertical rods 11, supporting legs 13 are fixedly installed on the bottom wall of the workbench 1, a bottom mold 2 is fixedly installed on the surface of the workbench 1, an electric telescopic rod 21 is fixedly installed on the surface of the top plate 12, and a top mold 22 is fixedly installed on the telescopic end of the electric telescopic rod 21. The two side walls opposite to the bottom mold 2 and the top mold 22 are respectively provided with a cavity 23, and the two side walls opposite to the bottom mold 2 and the top mold 22 are respectively provided with a plurality of cooling cavities 3, and the plurality of cooling cavities 3 are distributed in a ring shape around the cavity 23. The side walls of the bottom mold 2 and the top mold 22 are respectively provided with ventilation holes 31 connected to the cooling cavities 3. The bottom wall of the workbench 1 is fixedly provided with two groups of relatively distributed side panels 8, a bottom plate 4 is provided between the two groups of side panels 8, and a lifting assembly 5 cooperating with the bottom plate 4 is provided between the two groups of side panels 8. The lifting assembly 5 Component 5 is used to control the bottom plate 4 to reciprocate in the vertical direction between the two groups of side plates 8. A sprinkler mechanism 6 that cooperates with the cooling chamber 3 is provided on the surface of the workbench 1. The sprinkler mechanism 6 consists of a spray component 61 and a first drive component 62. The spray component 61 is located on the surface of the workbench 1 and is connected to the cooling chamber 3 on the surface of the top mold 22. The first drive component 62 is connected to the spray component 61. When the bottom plate 4 reciprocates in the vertical direction, the first drive component 62 intermittently sprays water quantitatively toward the side wall of the cooling chamber 3 by cooperating with the spray component 61. An evaporative heat absorption mechanism 7 is provided in the cooling chamber 3 on the surface of the bottom mold 2. The evaporative heat absorption mechanism 7 consists of a blowing component 71 and a second drive component 72. The blowing component 71 is located in the cooling chamber 3. The second drive component 72 is located on the surface of the bottom plate 4 and is connected to the blowing component 71. When the bottom plate 4 reciprocates in the vertical direction, the second drive component 72 accelerates the air flow speed in the cooling chamber 3 by cooperating with the blowing component 71.

[0025] The electric telescopic rod 21 pushes the top mold 22 to move in the vertical direction. After the top mold 22 and the bottom mold 2 are fitted together, injection molding is performed in the cavity 23. During the cooling and molding process, the lifting assembly 5 controls the bottom plate 4 to move back and forth in the vertical direction under the workbench 1. When the bottom plate 4 moves back and forth, the first driving assembly 62 cooperates with the spraying assembly 61. Cooling water can be intermittently and quantitatively sprayed to the side walls of the cooling chamber 3 in the bottom mold 2 and the top mold 22. The cooling water adheres to the side walls of the cooling chamber 3 and absorbs heat from the bottom mold 2 and the top mold 22. While spraying cooling water, the second driving assembly 72 cooperates with the blowing assembly 71 to effectively speed up the air flow speed in the cooling chamber 3. The high-speed air flow accelerates the evaporation of cooling water on the side walls of the cooling chamber 3. The evaporation of cooling water absorbs heat, which can further improve the heat dissipation efficiency of the bottom mold 2 and the top mold 22.

[0026] like Figure 2 , Figure 3 , Figure 5 , Figure 7 As shown, as a preferred embodiment of the present invention, the lifting assembly 5 includes two groups of fixed toothed discs 51 rotatably installed on the two side walls opposite to each other of the two groups of side plates 8, the two groups of side plates 8 are jointly rotatably installed with a rotating column 52 located below the fixed toothed disc 51, and a control toothed disc 53 is fixedly installed on the surface of the rotating column 52, the fixed toothed disc 51 is meshed and connected with the control toothed disc 53, and synchronous toothed discs 54 are respectively fixedly installed on the surfaces of the two groups of rotating columns 52, and the two groups of synchronous toothed discs 54 are jointly connected with a synchronous belt 55, and a plurality of groups of connecting rods 56 distributed in parallel are fixedly installed on the bottom wall of the bottom plate 4, and a limit plate 57 is jointly fixedly installed at the bottom ends of the plurality of connecting rods 56, and a guide groove 58 is opened on the surface of the limit plate 57, and a guide column 59 is jointly arranged at the position deviating from the center of the two relatively distributed fixed toothed discs 51, and the guide column 59 passes through the guide groove 58, and one end of a group of rotating columns 52 extends to the outside of the side plate 8 and is connected with a motor 50.

[0027] When in use, the motor 50 drives a group of rotating columns 52 to rotate and then drives the synchronous gear plate 54 to rotate. The two groups of synchronous gear plates 54 cooperate with the synchronous belt 55 to drive the two groups of rotating columns 52 to rotate synchronously. The rotating columns 52 drive the control gear plate 53 to rotate synchronously. The control gear plate 53 engages with the fixed gear plate 51 for transmission, and can drive multiple groups of fixed gear plates 51 to rotate synchronously on the surface of the side plate 8. The two relatively distributed groups of fixed gear plates 51 drive the guide column 59 to rotate synchronously. The guide column 59 cooperates with the guide groove 58 to drive the limit plate 57 to reciprocate in the vertical direction. The limit plate 57 cooperates with the connecting rod 56 to drive the bottom plate 4 to reciprocate in the vertical direction under the workbench 1.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, as a preferred embodiment of the present invention, the spray assembly 61 includes a plurality of water tanks 611 fixedly installed on the surface of the workbench 1 and located around the bottom mold 2, a water inlet 612 is provided on the surface of the water tank 611, a spray pipe 614 is fixedly installed on the top wall of the cooling chamber 3 in the top mold 22, a water guide pipe 613 is installed on the bottom end of the side wall of the water tank 611, and one end of the water guide pipe 613 away from the water tank 611 extends into the top mold 22 and is connected to the spray pipe 614.

[0029] When in use, a proper amount of cooling water is injected into the water tank 611 through the water inlet 612. When the base plate 4 moves back and forth in the vertical direction, the first drive assembly 62 controls the cooling water in the water tank 611 to be intermittently and quantitatively delivered to the guide pipe 613 and further delivered to the spray pipe 614. The spray pipe 614 sprays the cooling water evenly onto the side wall of the cooling chamber 3.

[0030] like Figure 2 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the first driving component 62 includes a piston plate 621 slidably installed in a water tank 611 along a vertical direction, a push-pull rod 622 is fixedly installed on the bottom wall of the piston plate 621, the push-pull rod 622 slides in the vertical direction and extends to the bottom of the workbench 1, the bottom end of the push-pull rod 622 extends to the bottom of the bottom plate 4 and is fixedly installed with a baffle 624, a return spring 623 is fixedly installed on the bottom wall of the water tank 611, and the telescopic end of the return spring 623 is connected to the piston plate 621.

[0031] Initially, the return spring 623 applies a thrust to the piston plate 621, and the piston plate 621 is at the top of the water tank 611. When the bottom plate 4 moves downward in the vertical direction, it pushes the baffle 624 to move downward synchronously. The baffle 624 cooperates with the push-pull rod 622 to pull the piston plate 621 to move downward synchronously in the water tank 611. When the piston plate 621 moves downward, it applies a thrust to the cooling water in the water tank 511, and thus the cooling water can be quantitatively transported to the water pipe 613.

[0032] like Figure 3 , Figure 4 , Figure 6 As shown, as a preferred embodiment of the present invention, the blowing assembly 71 includes a bearing rod 711 rotatably installed in the cooling cavity 3 on the surface of the bottom mold 2, and a plurality of groups of evenly distributed fan blades 712 are arranged on the surface of the bearing rod 711.

[0033] The spray pipe 614 sprays cooling water onto the side wall of the cooling chamber 3. When the bottom plate 4 moves back and forth in the vertical direction, the second driving component 72 controls the bearing rod 711 to rotate in the cooling chamber 3. The bearing rod 711 drives the fan blades 712 to rotate synchronously in the cooling chamber 3. The fan blades 712 can accelerate the flow speed of air in the cooling chamber 3.

[0034] like Figure 3 , Figure 4 , Figure 6 As shown, as a preferred embodiment of the present invention, the second driving assembly 72 includes a guide gear disk 721 fixedly mounted on the surface of the bearing rod 711, a column 722 is fixedly mounted on the surface of the base plate 4, the column 722 slides in the vertical direction and extends into the cooling chamber 3, a rack 723 is fixedly mounted on the top of the column 722, and the rack 723 is meshingly connected with the guide gear disk 721.

[0035] When the base plate 4 moves, it drives the column 722 to move synchronously back and forth in the vertical direction. The column 722 drives the rack 723 to move synchronously in the cooling chamber 3. When the rack 723 moves in the vertical direction, it engages with the guide gear disc 721 for transmission, and can drive the guide gear disc 721 to rotate in the cooling chamber 3. The guide gear disc 721 drives the bearing rod 711 to rotate in the cooling chamber 3.

[0036] like Figure 1 , Figure 2 As shown, as a preferred embodiment of the present invention, a positioning block 9 is fixedly installed on the side wall of the top mold 22, and the positioning block 9 is slidably connected to the vertical rod 11 along the vertical direction.

[0037] When the top mold 22 moves along the vertical direction, it drives the positioning blocks 9 to move synchronously on the surface of the vertical rod 11. Multiple groups of positioning blocks 9 can effectively improve the stability of the top mold 22 when it moves.

[0038] The working principle of the present invention is as follows: a proper amount of cooling water is injected into the water tank 611 through the water injection port 612, and the electric telescopic rod 21 pushes the top mold 22 to move in the vertical direction. After the top mold 22 and the bottom mold 2 are fitted together, injection molding is performed in the cavity 23. During the cooling and molding process, the motor 50 drives a group of rotating columns 52 to rotate and then drives the synchronous gear plate 54 to rotate. The two groups of synchronous gear plates 54 cooperate with the synchronous belt 55 to drive the two groups of rotating columns 52 to rotate synchronously. The rotating columns 52 drive the control gear plates 53 to rotate synchronously. The control gear plates 53 and the fixed gear plates 51 are meshed and driven, and multiple groups of fixed gear plates 51 can be driven to rotate synchronously on the surface of the side plate 8. The two relatively distributed groups of fixed gear plates 51 drive the guide columns 59 to rotate synchronously. The guide columns 59 and the guide grooves 58 cooperate with each other to drive the limit plates 57 to reciprocate in the vertical direction. The limit plates 57 cooperate with the connecting rods 56 to drive the bottom plate 4 to reciprocate in the vertical direction below the workbench 1.

[0039] When the bottom plate 4 moves downward in the vertical direction, it pushes the baffle plate 624 to move downward synchronously. The baffle plate 624 cooperates with the push-pull rod 622 to pull the piston plate 621 to move downward synchronously in the water tank 611. When the piston plate 621 moves downward, it applies thrust to the cooling water in the water tank 511, and then the cooling water can be quantitatively transported to the water guide pipe 613. The cooling water is intermittently quantitatively transported to the guide pipe 613 and further transported to the spray pipe 614, and the spray pipe 614 sprays the cooling water evenly to the side wall of the cooling chamber 3. The cooling water adheres to the side wall of the cooling chamber 3 and absorbs heat from the bottom mold 2 and the top mold 22. While spraying the cooling water, the bottom plate 4 moves and drives the column 722 to move synchronously back and forth in the vertical direction. The column 722 drives the rack 723 to move synchronously in the cooling chamber 3. When the rack 723 moves in the vertical direction, it meshes with the guide gear disc 721 to drive the guide gear disc 721 to rotate in the cooling chamber 3. The guide gear disc 721 drives the bearing rod 711 to rotate in the cooling chamber 3. The bearing rod 711 drives the fan blade 712 to rotate synchronously in the cooling chamber 3. The fan blade 712 can speed up the flow of air in the cooling chamber 3. The high-speed flow of air accelerates the evaporation of the cooling water on the side wall of the cooling chamber 3. The evaporation of the cooling water absorbs heat, which can further improve the heat dissipation efficiency of the bottom mold 2 and the top mold 22.

[0040] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
