DETAILED DESCRIPTION

[0029] like Figures 1 to 3 As shown, the present invention provides an intelligent molding device for motorcycle lights, comprising: a workbench 1, a mold box 2 is slidably installed on the workbench 1, a plurality of molds 3 are installed side by side in the mold box 2, a mold core 4 is provided between each of the plurality of molds 3, an injection hole 5 is provided on the mold core 4, the injection hole 5 is connected to an injection molding mechanism, a mounting cavity 301 and a drainage hole 302 connected to the mounting cavity 301 are provided on the mold 3, the drainage hole 302 is connected to the outside of the mold 3, a blocking plate 6 is slidably installed in the mounting cavity 301, the blocking plate 6 can block the injection hole 5, a slide plate 7 is slidably installed in the mounting cavity 301, the blocking plate 6 is slid to block the injection hole 5 and push the slide plate 7 on the adjacent mold 3 to slide, so that the blocking plate 6 pushes the excess injection molding material to the drainage hole 302 for discharge.

[0030] The working principle of the above technical solution is as follows: Figure 1 During injection molding, the injection molding mechanism injects more injection material than the mold core 4 from the injection hole 5 into the mold core 4. At this time, the blocking plate 6 and the slide plate 7 are both located in the installation cavity 301, the injection hole 5 is in an open state, and the slide plate 7 closes the drainage hole 302. After the injection molding is completed, the blocking plate 6 is slid along the direction of the injection hole 5 to close the injection hole 5, and the blocking plate 6 continues to slide to push the slide plate 7 on the adjacent mold 3 to slide so that the drainage hole 302 is opened, so that the excess injection material flows into the installation cavity 301 and is discharged from the drainage hole 302.

[0031] The beneficial effects of the above technical solution are as follows: the sealing plate 6 and the slide plate 7 are in the installation cavity 301 during injection molding, ensuring that the injection molding material flows smoothly into the mold core 4 during the injection molding process; after the injection molding is completed, the sealing plate 6 blocks the injection hole 5 to ensure the integrity of the molded lamp, and after demolding, there is no need to perform secondary processing on the excess parts of the molded lamp, saving the manufacturing time of the lamp; and because the sealing plate 6 on the mold 3 can block the injection hole 5, the integrity of the molded lamp can be ensured without setting a pressing film.

[0032] In one embodiment of the present invention, a cover plate 8 is fixedly mounted on the workbench 1, the mold box 2 is slidably connected to the cover plate 8, a through hole 801 cooperating with the injection hole 5 is provided on the cover plate 8, and the through hole 801 is connected to the injection mechanism.

[0033] The working principle of the above technical solution is as follows: Figure 3 After the injection molding is completed, the injection molding mechanism is closed and the through hole 801 is sealed, the mold box 2 slides out from under the cover plate 8, and the next mold box 2 slides into the lower side of the cover plate 8 so that the injection hole 5 matches the through hole 801, and then the injection molding mechanism is opened and the through hole 801 is opened to continue the injection molding.

[0034] The beneficial effect of the above technical solution is that by setting the through hole 801 on the cover plate 8 to cooperate with the injection hole 5, injection molding can be continued by simply sliding out the mold box 2 and sliding into the next mold box 2, which saves disassembly time and improves injection molding efficiency.

[0035] In one embodiment of the present invention, a scissor-type telescopic frame 9 is installed in the mold box 2, and the hinge points on both sides of the scissor-type telescopic frame 9 are slidably connected to the molds 3 one by one. The first side wall of the mold box 2 is fixedly connected to the adjacent mold 3, and the second side wall of the mold box 2 is slidably connected to the adjacent mold 3. The mold 3 sliding close to the second side wall of the mold box 2 can drive multiple molds 3 to slide at equal distances.

[0036] The working principle of the above technical solution is as follows: Figure 2 By moving the mold 3 close to the second side wall of the mold box 2, the scissor-type telescopic frame 9 can be stretched or contracted to make the multiple molds 3 slide at equal distances, thereby opening the mold core 4 and demolding the formed molded lamp.

[0037] The beneficial effect of the above technical solution is that by providing the scissor-type telescopic frame 9, multiple molds 3 can be slid synchronously and equidistantly to demould the molded lamps, thereby saving demoulding time and improving demoulding efficiency.

[0038] In one embodiment of the present invention, a baffle 10 is fixedly installed in the installation cavity 301, a first spring 11 is connected between the sealing plate 6 and the baffle 10, a slot 601 is provided on the sealing plate 6, and the upper limit sliding connection of the mold 3 is a clamping rod 303 extending into the installation cavity 301, and one end of the clamping rod 303 cooperates with the clamping slot 601 to enable the sealing plate 6 to be engaged or disengaged from the installation cavity 301.

[0039] The working principle of the above technical solution is as follows: Figure 1 Before the injection molding is completed, the clamping rod 303 is clamped in the clamping groove 601 so that the side of the blocking plate 6 close to the mold core 4 is in the same plane as the side wall of the injection hole 5. At this time, the first spring 11 is in a compressed state. After the injection molding is completed, the clamping rod 303 is slid to disengage the clamping rod 303 from the clamping groove 601. Under the action of the first spring 11, the blocking plate 6 slides in the direction close to the mold core 4 to block the mold core 4.

[0040] The beneficial effects of the above technical solution are as follows: by setting the clamping rod 303 to cooperate with the clamping slot 601, the side of the sealing plate 6 close to the mold core 4 is located in the same plane as the side wall of the injection hole 5 before the injection molding is completed, thereby ensuring the smooth progress of the injection molding. After the injection molding is completed, the sealing plate 6 automatically blocks the mold core 4 through the first spring 11.

[0041] In one embodiment of the present invention, the plurality of clamping rods 303 are connected in pairs via telescopic rods 12 .

[0042] The working principle and beneficial effects of the above technical solution are as follows: Figure 1 After the mold box 2 is slid out of the cover plate 8, the telescopic rod 12 can be pulled to make multiple clamping rods 303 slide synchronously to ensure that multiple blocking plates 6 block the corresponding mold cores 4 at the same time, saving time and manpower and improving efficiency; by setting the telescopic rod 12, the telescopic rod 12 can be extended and retracted when the mold 3 slides, ensuring smooth sliding of the mold 3 and smooth demoulding.

[0043] In one embodiment of the present invention, the scissor-type telescopic frame 9 on the mold 3 near the first side wall of the mold box 2 is threadedly connected with a screw 13, and the screw 13 extends out of the mold box 2. The screw 13 is symmetrically provided with opposite threads about the middle of the screw 13, and the two ends of the scissor-type telescopic frame 9 are respectively threadedly connected to the threads on both sides of the screw 13.

[0044] The working principle of the above technical solution is as follows: Figure 1 By setting a screw rod 13, when the screw rod 13 is rotated, the two ends of the scissor-type telescopic frame 9 on the mold 3 close to the first side wall of the mold box 2 can be driven to slide toward the middle of the screw rod 13, so that the scissor-type telescopic frame 9 is stretched or contracted, thereby causing multiple molds 3 to slide.

[0045] The beneficial effect of the above technical solution is that manpower is saved by arranging the screw 13 as a driving mechanism for driving the mold 3 to slide.

[0046] In one embodiment of the present invention, a second spring 14 is connected between the slide plate 7 and the baffle 10 .

[0047] The working principle and beneficial effect of the above technical solution are that, by providing the second spring 14 , it is convenient for the slide plate 7 to return to its original position after losing the squeezing of the blocking plate 6 .

[0048] A method for implementing a motorcycle headlight intelligent molding device comprises the following steps:

[0049] S1: Slide the mold box 2 to the lower side of the cover plate 8 so that the injection hole 5 matches the through hole 801;

[0050] S2: Open the through hole 801, and inject the injection material that is more than the mold core 4 from the injection hole 5 into the mold core 4 through the injection mechanism;

[0051] S3: After the injection molding is completed, the injection molding mechanism is closed and the through hole 801 is sealed;

[0052] S4: slide the mold box 2 down from under the cover plate 8 to expose the clamping rods 303, pull the telescopic rod 12 to drive the multiple clamping rods 303 to slide so that the blocking plate 6 is out of the clamping state and slides to block the injection hole 5, and continue to slide the mold box 2 so that the mold box 2 is completely slid out from under the cover plate 8;

[0053] S5: After the lamp is formed, the screw 13 is rotated to make the multiple molds 3 slide synchronously and equidistantly to open the mold core 4 and then demold the molded lamp;

[0054] S6: Slide the next mold box 2 to the lower side of the cover plate 8 and repeat steps S1 to S5.

[0055] The working principle and beneficial effects of the above technical solution: through step S2, more injection molding material than the core 4 is injected into the core 4 from the injection hole 5, thereby ensuring the integrity of the molded lamp, avoiding the incomplete molding mold caused by too little injection molding material, or the trouble of accurately calculating the amount of injection molding material when the volume of the injection molding material and the core 4 are consistent; through step S4, it is ensured that the injection molding material flows smoothly into the core 4 during the injection molding process, and after the injection molding is completed, the sealing plate 6 blocks the injection hole 5, thereby ensuring the integrity of the molded lamp, and after demolding, there is no need to perform secondary processing on the excess parts of the molded lamp, thereby saving the manufacturing time of the lamp.

[0056] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
