TECHNICAL FIELD

[0002] In the field of motorcycle covering part injection processing, the heat dissipation efficiency of the mold directly affects the forming quality and production efficiency of the product. With the increasing complexity of motorcycle design and the continuous improvement of consumers' quality requirements for products, traditional injection mold faces many challenges in heat dissipation.

DETAILED DESCRIPTION

[0029] In order to further understand the characteristics, technical means and specific purposes and functions reached by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0030] Referring to Figure 1 and Figure 8As shown in the figure, the motorcycle cover high-efficiency heat dissipation type injection molding mold includes a workbench 1, a lower mold 2 arranged on the workbench 1, a mold groove 3 opened on the lower mold 2, an upper mold 11 arranged in a vertical direction on the workbench 1, a cylinder 4 mounted on the workbench 1 to drive the upper mold 11 to ascend or descend in a vertical direction, and a cooling mechanism 5 arranged on the lower mold 2 to quickly cool the mold in the mold groove 3. The cooling mechanism 5 includes a cooling chamber 51 and a discharge and return mechanism 6 to quickly discharge and recycle the cooling water in the cooling chamber 51. The motorcycle cover high-efficiency heat dissipation type injection molding mold further includes an air cooling mechanism 7 arranged on the lower mold 2 to cool the temperature in the cooling chamber 51. A plurality of vertical pipes are arranged on the workbench 1 and gap-fit with the upper mold 11. The upper mold 11 can ascend or descend in a vertical direction along the vertical pipes.

[0031] Firstly, the cylinder 4 can drive the upper mold 11 to ascend vertically. When the mold groove 3 in the lower mold 2 needs to be cooled, the first cooling pipe 53 and the spray pipe arranged in the cooling chamber 51 can quickly cool the mold after clamping. The discharge and return mechanism 6 can quickly discharge the water after spraying, so as to avoid the water after heat exchange remaining in the lower mold 2 to cause heat accumulation and affect the quick cooling effect of the mold.

[0032] As shown in the figure, Figure 3 and Figure 5 The cooling mechanism 5 further includes a water pump 52, a first cooling pipe 53, a spray chamber 54, a spray pipe 55, and a water tank 56. The water pump 52 is arranged on the workbench 1 and close to one side of the lower mold 2. The water inlet end of the first cooling pipe 53 is arranged at the water outlet end of the water pump 52. The first cooling pipe 53 is arranged in the cooling chamber 51. The spray chamber 54 is opened on the lower mold 2 and below the mold groove 3. The spray pipe 55 is arranged on the first cooling pipe 53 and in the spray chamber 54 and has a plurality of spray pipes. The water tank 56 is arranged on the workbench 1. The water inlet end of the water tank 56 is connected with the water outlet end of the first cooling pipe 53 and the spray pipe. The water outlet end of the water tank 56 is connected with the water inlet end of the water pump 52. An evaporator for cooling water is arranged in the water tank 56.

[0033] When the mold needs to be quickly cooled, the water pump 52 is first started, and then the cooling water in the water tank 56 can flow through the first cooling pipe 53. Since the first cooling pipe 53 is located in the cooling chamber 51, and the cooling chamber 51 is a square ring around the lower mold 2, at this time the first cooling pipe 53 can wrap the mold for cooling. When water flows in the first cooling pipe 53, cooling water can be input into the spraying pipe 55 at the same time. Since the spraying pipe 55 is located in the spraying chamber 54 and below the mold groove 3, the cooling water in the spraying pipe 55 is uniformly sprayed in the spraying chamber 54. Since the distance between the spraying chamber 54 and the mold groove 3 is close, the heat of the mold in the mold groove 3 can be quickly cooled by the spraying pipe 55 in the spraying chamber 54, which can timely take away the heat, thereby significantly improving the cooling efficiency.

[0034] Referring to Figure 3 and Figure 5 As shown in the figures, the discharge backflow mechanism 6 includes a discharge chamber 61, a first positioning rod 62, a closed sealing plate 63, a recovery tank 64, and a backflow pipe 65. The discharge chamber 61 is respectively provided on the workbench 1 and the lower mold 2, and is located below the spraying chamber 54. The discharge chamber 61 is used to discharge the sprayed water. The first positioning rod 62 is provided on the workbench 1 and is located below the discharge chamber 61. The closed sealing plate 63 is rotatably provided on the first positioning rod 62 and is used to shield and seal the discharge chamber 61. The recovery tank 64 is provided on the workbench 1 and is located below the discharge chamber 61. The recovery tank 64 is used to collect the discharged cooling water. The backflow pipe 65 is provided on the recovery tank 64 and is connected with the water tank 56 through the water pump 52.

[0035] After the mold is formed and the upper mold 11 is raised by the action of the air cylinder 4, and the cooling water in the discharge chamber 61 needs to be discharged in time, during the rising of the upper mold 11, the closed sealing plate 63 can be driven to rotate and tilt along the first positioning rod 62 until the closed sealing plate 63 loses the shielding and sealing of the discharge chamber 61. At this time, the cooling water in the discharge chamber 61 can be discharged into the recovery tank 64. Then the water pump 52 is started, which can transport the water in the recovery tank 64 into the water tank 56 for timely cooling. Thus, the sprayed water can be automatically discharged and collected for cooling, on the one hand, without the need for manual timely discharge of the cooling water, and on the other hand, the heat of the sprayed cooling water is prevented from accumulating in the discharge chamber 61 and the cooling chamber 51, and the discharged cooling water can be timely recovered and cooled.

[0037] When the cylinder 4 drives the upper mold 11 to slide in a vertical direction, the elastic pulling rope 69 is in a stretched state in this process, and drives the sliding block 67 to slide in a horizontal linear direction along the guide rod 66, and when the sliding block 67 is pulled, the hinged rod 68 drives the closing sealing plate 63 to open at an angle along the first positioning rod 62, so that when the mold injection is completed and the upper mold 11 is separated from the lower mold 2, the closing sealing plate 63 can be automatically opened, and the water after heat exchange can be discharged in time; during the process of closing the upper mold 11 and the lower mold 2, the elastic pulling rope loses the stretching effect on the sliding block 67, and at this time the first reset spring 691 drives the sliding block 67 to move along the guide rod 66 and close to the closing sealing plate 63, and in this process the hinged rod 68 drives the closing sealing plate 63 to swing at an angle, until the closing sealing plate 63 shields and seals the exhaust chamber 61, achieving the automatic discharge and sealing effect of the cooling water in the exhaust chamber 61.

[0038] As shown in Figure 6 and Figure 7 , the air cooling mechanism 7 comprises a heat dissipation chamber 71, a micro heat dissipation device 72 and a filter screen 73; the heat dissipation chamber 71 is arranged on the lower mold 2 and is used to cool the first cooling pipe 53 in the cooling chamber 51; the micro heat dissipation device 72 is arranged on the lower mold 2 and has a pair; the filter screen 73 is arranged on the micro heat dissipation device 72.

[0039] When the spraying pipe 55 sprays the spraying chamber 54, the micro heat dissipation device 72 can be started to cool the heat dissipation chamber 71, and the heat dissipation chamber 71 is arranged on the cooling chamber 51, so that air can directly act on the first cooling pipe 53 in the cooling chamber 51 through the filter screen 73 and the heat dissipation chamber 71 for air cooling, which can improve the cooling effect of the first cooling pipe 53 on the mold, and can avoid the generation of water droplets in the cooling chamber 51 due to the too low temperature in the mold, and the arrangement of the filter screen 73 can reduce the entry of dust.

[0040] As shown inFigure 6 And Figure 7 As shown in the drawings, the air cooling mechanism 7 further comprises a shielding plate 74, a stroke groove 75, a connecting block 76, a connecting rod 77 and a cleaning rod 78; the shielding plate 74 is rotationally arranged on the lower die 2; the stroke groove 75 is opened on the lower die 2 and has a pair; the connecting block 76 is vertically slidably arranged on the stroke groove 75 and has a pair; the connecting rod 77 is rotationally arranged on the shielding plate 74 and the connecting block 76, respectively; the cleaning rod 78 is arranged on the connecting block 76 and abuts against the outer wall of the filter screen 73; the shielding plate 74 is provided with a magnetic block 741, and the lower die 2 is provided with a magnetic groove 742 which is attracted to the magnetic block 741; when the shielding plate 74 is opened, the magnetic block 741 is attracted to the magnetic groove 742, so as to open and fix the shielding plate 74.

[0041] When the dust on the filter screen 73 needs to be cleaned, the shielding plate 74 is opened; when the shielding plate 74 is opened at an inclination angle, the shielding plate 74 drives the connecting block 76 to vertically slide along the stroke groove 75 opened on the lower die 2 through the connecting rod 77 in the process; when the connecting block 76 vertically slides, the cleaning rod 78 drives the abutting filter screen 73 to be cleaned; when the miniature heat dissipation device 72 is started, the filter screen 73 can be automatically cleaned by opening the shielding plate 74; when the mold is closed and the miniature heat dissipation device 72 is closed, the shielding plate 74 can also be closed to shield the filter screen 73, so as to reduce the adhesion of dust on the filter screen 73 in the idle state, and reduce the cost of manual cleaning.
