[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0034] Referring to Figure 1 , an embodiment provided by the present utility model: an injection mold for an automotive welcome light face cover, including second support legs 8, second support legs 8 and first support legs 3, both of which are provided in two groups and are fixedly connected to the same group of bases at the bottom. The top of the second support leg 8 is hinged with a lower mold 1. A cavity is formed at the top of the lower mold 1. Due to the hinging effect of the lower mold 1, the lower mold 1 can be turned backward. A support frame 4 is fixedly connected to the top of the lower mold 1. The support frame 4 plays a fixing role for the hydraulic cylinder 5 and also plays a guiding role for the upper mold 2. A hydraulic cylinder 5 is fixedly connected to the top of the support frame 4. By starting the hydraulic cylinder 5, the upper mold 2 is driven to move vertically. The output end of the hydraulic cylinder 5 is fixedly connected to the upper mold 2. By moving the upper mold 2 downward to be combined with the lower mold 1, the shape of the welcome light face cover is formed. A cooling component 6 is arranged on the inner wall of the lower mold 1. Through the cooling component 6, the molten plastic in the cavity is cooled, thereby accelerating the molding of the part. A mounting and dismounting component 7 is arranged at the bottom of the inner wall of the lower mold 1. By arranging the mounting and dismounting component 7, it is convenient to install or disassemble the bottom plate 71, so as to facilitate the maintenance of the cooling component 6 and the water cooling component 67 arranged inside the lower mold 1. The bottom of the lower mold 1 is in contact with the first support leg 3. The second support leg 8 and the first support leg 3 play a stable supporting role for the lower mold 1.

[0035] Referring to Figures 2 - 4, the cooling assembly 6 includes an air inlet fan 62. By starting the air inlet fan 62, the outside air is sucked into the interior of the lower mold 1. At the right end of the back of the air inlet fan 62, a shunt pipe 63 is fixedly connected. There are two groups of shunt pipes 63 symmetrically distributed. Through the shunt pipes 63, the air sucked by the air inlet fan 62 is discharged from the shunt pipes 63, thus forming a convection effect. The inner wall of the lower mold 1 is fixedly connected with a connecting rod 64. The connecting rod 64, the rotating block 65 and the square plate 66 are all made of copper and are provided in multiple groups, having good heat conduction effects, so as to disperse the heat at the top of the inner wall of the lower mold 1. The outer circumference of the connecting rod 64 is rotatably connected with a rotating block 65. Through the rotation effect of the rotating block 65, the square plate 66 can be driven to rotate. The outer wall of the rotating block 65 is fixedly connected with the square plate 66. Through the rotation effects of multiple groups of square plates 66, the wind can be further dispersed to ensure the uniformity of heat dissipation. The right inner wall of the lower mold 1 is penetrated and fixedly connected with an air outlet fan 61. Through the air outlet fan 61, the hot air inside the lower mold 1 is discharged. A water cooling assembly 67 is arranged on the inner wall of the lower mold 1. Through the water cooling assembly 67, the interior of the lower mold 1 can be cooled by circulating cooling water.

[0036] Refer to Figures 4 - 6 , the assembling and disassembling assembly 7 includes a bottom plate 71. The inner wall of the bottom plate 71 is threadedly connected with a bolt 72. By screwing the bolt 72, it is convenient to install the bottom plate 71 at the bottom of the lower mold 1 or disassemble the bottom plate 71. The inner wall of the lower mold 1 is fixedly connected with a fixing block 73. The fixing block 73 and the bolt 72 are both symmetrically distributed in two groups to improve the fixing effect after the bottom plate 71 is installed. The front inner wall of the first support leg 3 is elastically connected with a wedge block 75 through a spring 74. Through the elastic force of the spring 74, the wedge block 75 always maintains the clamping effect with the buckle 76 without external force, so as to limit the lower mold 1. The right end of the front of the lower mold 1 is fixedly connected with a buckle 76. Through the fixing effect of the buckle 76, the buckle 76 is prevented from falling off.

[0037] Refer to Figure 2 and Figure 4 , the water cooling assembly 67 includes a refrigeration box 675. The refrigeration box 675 is a prior art. By starting the refrigeration box 675, the water on the inner wall of the refrigeration box 675 is cooled. The front of the refrigeration box 675 is fixedly connected with a water pump 672. The water pump 672 is a prior art. By starting the water pump 672, the water inside the refrigeration box 675 can be conveyed into the water inlet pipe 673. The output end of the water pump 672 is fixedly connected with a water inlet pipe 673. Through the water inlet pipe 673, the cooling water is conveyed into the condensing pipe 671. The left end of the water inlet pipe 673 is fixedly connected with a condensing pipe 671. Through the cooling water in the condensing pipe 671, the interior of the lower mold 1 is cooled. The right side of the condensing pipe 671 is fixedly connected with a water outlet pipe 674. Through the water outlet pipe 674, the water with reduced cooling effect in the condensing pipe 671 is conveyed into the refrigeration box 675.

[0038] Reference Figure 1 and Figure 3 , the outer wall of the air inlet fan 62 penetrates and is fixedly connected to the left inner wall of the lower mold 1. Through the fixing effect of the air inlet fan 62, the air inlet fan 62 is prevented from falling off. The outer wall of the shunt pipe 63 is fixedly connected to the back inner wall of the lower mold 1. Through the fixing effect of the shunt pipe 63, the shunt pipe 63 is prevented from falling off. An air outlet is provided on the front of the shunt pipe 63. Since multiple groups of air outlets are provided, the air in the shunt pipe 63 is discharged through the air outlets, so that the discharged air blows the square plate 66, causing the square plate 66 to rotate. The inner wall of the upper mold 2 is slidably connected to the outer wall of the support frame 4.

[0039] Reference Figure 4 and Figure 6 , the outer wall of the bottom plate 71 is inserted into the bottom inner wall of the lower mold 1. By inserting the bottom plate 71 into the lower mold 1, the bottom plate 71 can be installed at the bottom of the lower mold 1. The outer wall of the bolt 72 is threadedly connected to the inner wall of the fixing block 73. One end of the spring 74 is fixedly connected to the front inner wall of the first support leg 3, and the other end of the spring 74 is fixedly connected to the back of the wedge block 75. Through the fixing effect of the spring 74, the wedge block 75 is kept fixed and prevented from falling off.

[0040] Reference Figure 2 and Figure 4 , the left side of the refrigeration box 675 is fixedly connected to the right side of the lower mold 1. Through the fixing effect of the refrigeration box 675, the refrigeration box 675 is prevented from falling off. The outer circumference of the condensing pipe 671 is fixedly connected to the top inner wall of the lower mold 1. Through the fixing effect of the condensing pipe 671, the condensing pipe 671 is prevented from falling off. The right end of the water outlet pipe 674 is fixedly connected to the back of the refrigeration box 675. Through the fixing effect of the water outlet pipe 674, the water outlet pipe 674 is prevented from falling off. The outer circumference of the water inlet pipe 673 penetrates the right inner wall of the lower mold 1, and the outer circumference of the water outlet pipe 674 penetrates the right inner wall of the lower mold 1.

[0041] Reference Figure 1 and Figure 6 , the outer wall of the wedge block 75 is slidably connected to the front inner wall of the first support leg 3. Through the sliding effect of the wedge block 75, the wedge block 75 is engaged or disengaged with the buckle 76. The outer wall of the wedge block 75 is engaged with the inner wall of the buckle 76. Through the engagement of the wedge block 75 and the buckle 76, the first support leg 3 limits the lower mold 1.

[0042] Working principle: When it is necessary to injection-mold the automotive welcome light face cover, the staff starts the hydraulic cylinder 5 to drive the upper mold 2 to slide downward, so that the lower mold 1 and the upper mold 2 are closed. The staff injects molten plastic into the upper mold 2 and the lower mold 1 through the injection hole to form the welcome light face cover. After the injection molding is completed, the staff starts the air inlet fan 62 and the air outlet fan 61. The air inlet fan 62 sucks the outside air into the shunt pipe 63, and the air is discharged into the interior of the lower mold 1 through multiple air outlet openings provided on the shunt pipe 63 to form air convection. At the same time, the discharged air flow blows multiple square plates 66 to rotate, dispersing the wind force to ensure the uniformity of heat dissipation. At the same time, the heat on the top of the inner wall of the lower mold 1 is conducted to the square plates 66 through the connecting rod 64 and the rotating block 65 for heat dissipation, and the hot air inside the lower mold 1 is discharged through the air outlet fan 61.

[0043] The staff starts the refrigeration box 675 and the water pump 672. The water pump 672 conveys the cooling water inside the refrigeration box 675 into the water inlet pipe 673, and the cooling water is conveyed into the condensing pipe 671 through the water inlet pipe 673. The cooling water in the condensing pipe 671 cools the interior of the lower mold 1, and the water after cooling the lower mold 1 is conveyed into the refrigeration box 675 through the water outlet pipe 674, so that the cooling water in the condensing pipe 671 can circularly cool the interior of the lower mold 1.

[0044] When the cooling components 6 and the water cooling components 67 inside the lower mold 1 need to be maintained, the staff presses the wedge block 75 to release the clamping effect between the wedge block 75 and the buckle 76, and at the same time releases the limiting effect on the lower mold 1. The lower mold 1 is flipped backward. At the same time, the staff loosens the bolt 72 to release the fixing effect on the bottom plate 71, and the bottom plate 71 is removed, which is convenient for the staff to maintain the parts inside the lower mold 1. After the maintenance is completed, the staff installs the bottom plate 71 at the bottom of the lower mold 1, tightens the bolt 72, and flips the lower mold 1 forward to reset, so that the wedge block 75 is clamped with the buckle 76 under the elastic force of the spring 74, and at the same time limits the lower mold 1 to keep the lower mold 1 fixed, completing the maintenance work.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
