Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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] See also Figure 1-4 The utility model provides a technical solution: an automobile injection mold with a surface cladding function, comprising a work surface 1, an injection mold frame 2, a hydraulic cylinder 3, an upper mold 4, an injection tube 5, a lower mold 6, a hydraulic support 7, a supporting plate 8, a circulating water pipe 9, an electric telescopic rod 10, a push plate 11, a conveyor belt 12, a support frame 13, a dust suction tube 14, a cleaning brush 15, a fixing plate 16, a bottom plate 17 and a laser 18, such as Figure 1 and Figure 3As shown, an injection mold frame 2 is installed on the upper surface of the work surface 1, and the work surface 1 supports and stabilizes the injection mold frame 2. A hydraulic cylinder 3 is installed on the upper end of the injection mold frame 2, and an upper mold 4 is installed on the lower end of the hydraulic cylinder 3. A lower mold 6 is installed on the upper surface of the work surface 1. When the hydraulic cylinder 3 is turned on, the hydraulic cylinder 3 drives the upper mold 4 to move toward the lower mold 6, and the upper mold 4 is moved into the lower mold 6. An injection tube 5 is installed on the upper end of the upper mold 4, and the injection tube 5 is connected to an external injection molding box. When the external high-pressure pump is turned on, the injection material is transported to the upper mold 4 and the lower mold 6 through the injection tube 5.

[0024] A hydraulic support 7 is installed below the work surface 1, and a support plate 8 is installed on the upper end of the hydraulic support 7. The support plate 8 can be used as a support plate at the bottom end of the lower mold 6 to receive injection materials and assist mold molding. A circulation groove is reserved inside the lower mold 6, and a circulation water pipe 9 is connected to the left end of the circulation groove. The circulation water pipe 9 is connected to an external cooling box. When the water pump is turned on, the water pump transports the coolant to the circulation groove in the lower mold 6 through the circulation water pipe 9, which accelerates mold cooling and molding, reduces cooling time, and improves efficiency.

[0025] After the mold is cooled and formed, the hydraulic cylinder 3 drives the upper mold 4 away from the lower mold 6, and then the hydraulic support 7 is opened. The hydraulic support 7 drives the supporting plate 8 to rise, and the supporting plate 8 assists in demoulding the mold in the lower mold 6, and pushes the formed automobile mold upward. Driven by the hydraulic support 7, the supporting plate 8 is flush with the top surface of the lower mold 6. A support plate is installed on the left side of the injection mold frame 2, and an electric telescopic rod 10 is installed on the upper surface of the support plate. A push plate 11 is installed at the end of the electric telescopic rod 10. After the mold is moved out, the electric telescopic rod 10 is opened, and the electric telescopic rod 10 drives the push plate 11 to move to the right, and the push plate 11 pushes the formed mold to the right;

[0026] like Figure 2 and Figure 4 As shown, a conveyor belt 12 is installed at the right end of the upper surface of the work table 1, and the mold is pushed onto the conveyor belt 12. The conveyor belt 12 is turned on, and the conveyor belt 12 drives the mold to move to the right. A support frame 13 is installed at the right end of the upper surface of the work table 1, and a dust suction pipe 14 is installed at the upper end of the support frame 13. A cleaning brush 15 is installed at the end of the dust suction pipe 14. When the conveyor belt 12 moves the mold to the right, the cleaning brush 15 fits the upper surface of the mold to clean the dust and impurities on the surface of the mold. The external vacuum cleaner is turned on, and the dust and impurities are sucked into the vacuum cleaner through the dust suction pipe 14, which is convenient for cleaning and collecting dust and impurities, ensuring that the mold surface is clean and tidy, and avoiding affecting the subsequent cladding work.

The cleaned mold is moved to the bottom of the laser 18 driven by the conveyor belt 12, and the laser 18 is turned on. The laser 18 melts the alloy powder on the mold surface to strengthen the surface of the automobile mold. The screws and locking nuts on the surface of the bottom plate 17 are unscrewed to facilitate the quick disassembly, replacement and maintenance of the laser 18. After the cladding is completed, the conveyor belt 12 facilitates the transportation of the automobile mold, thereby improving the degree of automation and work efficiency.
