Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1~Figure 4 As shown, this embodiment proposes a processing mold for producing automobile sealing strips, including a carrier frame 1, a lower mold 2 is fixedly connected to the top of the carrier frame 1, a support frame 3 is fixedly connected to one end of the carrier frame 1, a hydraulic rod 4 is fixedly connected to the top of the support frame 3, an output end of the hydraulic rod 4 is fixedly connected to an upper mold 5 adapted to the lower mold 2, a transmission frame 6 is fixedly connected to one side of the carrier frame 1, a transmission screw 7 is rotatably connected to the inner side of the transmission frame 6, a transmission motor 8 is fixedly connected to one end of the transmission frame 6, and the output end of the transmission motor 8 is fixedly connected to the transmission screw 7, and a cleaning mechanism 9 is arranged on the outer side of the transmission screw 7, and the cleaning mechanism 9 is used to clean the residual raw materials at the lower mold 2 and the upper mold 5;

[0024] It can be understood that the hydraulic rod 4 is started to push the upper mold 5 to move downward until the upper mold 5 is assembled with the lower mold 2, so that a complete cavity is formed between the upper mold 5 and the lower mold 2, and then the raw material of the automobile sealing strip is injected into the cavity through the upper mold 5, so that the automobile sealing strip is formed in the cavity. After the raw material of the automobile sealing strip is cooled, the hydraulic rod 4 is started to separate the upper mold 5 from the lower mold 2, and the formed automobile sealing strip can be removed;

[0025] Furthermore, the top end of the lower mold 2 and the bottom end of the upper mold 5 are both provided with cavities, and the two cavities are adapted to each other;

[0026] In more detail, the top of the upper mold 5 is fixedly connected with an injection tube, and the bottom end of the injection tube extends to the cavity of the upper mold 5;

[0027] The top end of the support frame 3 is also vertically slidably connected to a linear slide rod, and the bottom end of the linear slide rod is fixedly connected to the upper mold 5;

[0028] Example 2

[0029] like Figure 1~Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a cleaning mechanism 9;

[0030] In the present embodiment, the cleaning mechanism 9 includes a transmission seat 10, an assembly seat 11, a central shaft 12, a cleaning roller 13, a drive motor 14, a drive bevel gear 15, a matching bevel gear 16 and a linkage frame 17. The outer side of the transmission screw 7 is threadedly connected to the transmission seat 10, and the top of the transmission seat 10 is fixedly connected to the assembly seat 11. One end of the assembly seat 11 is longitudinally rotatably connected to the central shaft 12, and one end of the central shaft 12 is fixedly connected to the cleaning roller 13. The top of one end of the assembly seat 11 is fixedly connected to the drive motor 14, and the output end of the drive motor 14 is fixedly connected to the drive bevel gear 15. The middle part of the central shaft 12 is fixedly connected to the matching bevel gear 16, and the matching bevel gear 16 is meshed with the drive bevel gear 15. The other end of the assembly seat 11 is laterally slidably connected to the linkage frame 17;

[0031] It can be understood that the transmission motor 8 is started to drive the transmission screw 7 to rotate, adjust the position of the assembly seat 11, and at the same time start the drive motor 14, prompting the drive bevel gear 15 to turn the matching bevel gear 16, thereby driving the central shaft 12 to rotate, and cooperate with the connection between the central shaft 12 and the cleaning roller 13, so that the cleaning roller 13 can contact the cavity of the lower mold 2 and the upper mold 5;

[0032] Furthermore, a stabilizing slide bar is fixedly connected to the inner side of the transmission frame 6, and the transmission seat 10 is also slidably connected to the outer side of the stabilizing slide bar;

[0033] In detail, a limit slot is transversely provided at the other end of the assembly seat 11, and the linkage frame 17 is slidably connected inside the limit slot. By setting the limit slot, the displacement of the linkage frame 17 can be stably guided to avoid uncontrollable displacement of the linkage frame 17.

[0034] The cleaning mechanism 9 also includes a cleaning frame 18, a shunt pipe 19, a de-impurity nozzle 20, a de-impurity fan 21, a transmission hose 22, an eccentric transmission plate 23 and a linkage rod 24. One end of the linkage frame 17 is fixedly connected to the cleaning frame 18, the inner side of the cleaning frame 18 is fixedly connected to the shunt pipe 19, and the outer side of the shunt pipe 19 is longitudinally fixedly connected to a plurality of de-impurity nozzles 20. The top of the other end of the assembly seat 11 is fixedly connected to the de-impurity fan 21, and the output end of the de-impurity fan 21 is fixedly connected to the transmission hose 22, and the end of the transmission hose 22 away from the de-impurity fan 21 is connected to the shunt pipe 19, and the other end of the central shaft 12 is fixedly connected to the eccentric transmission plate 23, and one end of the eccentric transmission plate 23 is rotatably connected to the linkage rod 24, and the end of the linkage rod 24 away from the eccentric transmission plate 23 is also rotatably connected to the linkage frame 17;

[0035] In summary, the linkage rod 24 is connected to the linkage frame 17, so that the linkage frame 17 moves back and forth under the limit of the assembly seat 11, thereby driving the cleaning frame 18 to wipe the cavities of the upper mold 5 and the lower mold 2, and the impurity removal fan 21 can be started to introduce the external airflow to the cleaning frame 18 through the transmission hose 22, and spray it to the upper mold 5 and the lower mold 2 through the impurity removal nozzle 20, so that the residual raw materials at the upper mold 5 and the lower mold 2 can be blown off;

[0036] Among them, the outer side of the cleaning roller 13 and the top and bottom ends of the cleaning frame 18 are fixedly connected with a dust removal brush, and the dust removal brush is made of soft material. The setting of the dust removal brush can effectively improve the contact effect between the cleaning roller 13 and the cleaning frame 18 and the upper mold 5 and the lower mold 2, thereby improving the overall cleaning efficiency;

[0037] Here, the top and bottom ends of the impurity removal nozzle 20 are fixedly connected with air flow nozzles, and the interior of the air flow nozzle is fixedly connected with an impurity blocking net. By utilizing the setting of the air flow nozzle, the air flow can be efficiently sprayed toward the upper mold 5 and the lower mold 2, and in combination with the setting of the impurity blocking net, residual raw materials can be prevented from entering the impurity removal nozzle 20 through the air flow nozzle.

[0038] A specific application of the above two embodiments is to start the hydraulic rod 4 to push the upper mold 5 to move downward until the upper mold 5 is assembled with the lower mold 2, so that a complete cavity is formed between the upper mold 5 and the lower mold 2, and then the raw material of the automobile sealing strip is injected into the cavity through the upper mold 5 to form the automobile sealing strip in the cavity. After the raw material of the automobile sealing strip is cooled, the hydraulic rod 4 is started to separate the upper mold 5 from the lower mold 2, and the formed automobile sealing strip can be removed;

[0039] The transmission motor 8 can be started to drive the transmission screw 7 to rotate. Under the connection between the transmission screw 7 and the transmission seat 10, the transmission screw 7 can drive the transmission seat 10 to move horizontally, so as to adjust the position of the assembly seat 11. At the same time, the driving motor 14 is started to prompt the driving bevel gear 15 to shift the matching bevel gear 16, so as to drive the central shaft 12 to rotate, and cooperate with the connection between the central shaft 12 and the cleaning roller 13, so that the cleaning roller 13 can contact the cavity of the lower mold 2 and the upper mold 5 to clean the residual raw materials in the cavity;

[0040] At the same time, the connection between the central shaft 12 and the eccentric transmission plate 23 is coordinated so that the eccentric transmission plate 23 can follow the rotation of the central shaft 12, reciprocatingly push and pull the linkage rod 24, and coordinate the connection between the linkage rod 24 and the linkage frame 17, so that the linkage frame 17 can move back and forth under the limit of the assembly seat 11, thereby driving the cleaning frame 18 to wipe the cavity of the upper mold 5 and the lower mold 2, thereby assisting the operation of the cleaning roller 13, and starting the impurity removal fan 21 to introduce the external airflow into the cleaning frame 18 through the transmission hose 22, and spray it onto the upper mold 5 and the lower mold 2 through the impurity removal nozzle 20, thereby being able to blow off the residual raw materials at the upper mold 5 and the lower mold 2.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
