Description

Technical Field

[0001] The utility model relates to the technical field of injection molding devices, and in particular to an injection molding device for a charging pile shell. Background Art

[0002] Charging pile is a kind of energy replenishment device that provides electric vehicles with electricity. Its function is similar to the gas pump in the gas station. It can be fixed on the ground or wall and installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and residential parking lots. It can charge various types of electric vehicles according to the voltage and current adjustment. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform the corresponding charging operation and print the cost data. The charging pile display can display data such as charging amount, cost, and charging time.

[0003] In the prior art, the shell of the charging pile is generally produced by injection molding. The upper mold plate is driven downward by a hydraulic cylinder, and the raw materials are added into the mold through the pouring port on the surface of the upper mold plate. The lower mold plate and the upper mold plate are fixed and then injection molded. However, when fixing the injection mold, it is often necessary to align and close the two molds and then fix them with bolts. However, this method is time-consuming and affects the efficiency of disassembly and assembly between molds. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a charging pile shell injection molding device, which aims to improve the common method of fixing the injection mold, which is often to align and close the two molds and then fix them with bolts. However, this method is time-consuming and affects the disassembly and assembly efficiency between the molds.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a charging pile shell injection molding device, comprising a lower mold and an upper mold arranged on the lower mold, one end of the lower mold is fixedly connected to a mounting frame, a hydraulic cylinder is installed above the mounting frame, four guide rods are arranged on the upper outer wall of the lower mold, and a symmetrical positioning frame is fixedly connected to the outer wall of the lower mold close to the guide rods;

[0007] One side outer wall of the upper mold is fixedly connected to the output end of the hydraulic cylinder, a guide hole slidably connected to the outer wall of the guide rod is opened on the surface of the upper mold, a symmetrical fixing rod is fixedly connected to one side of the upper mold, two spherical blocks are installed on the outer wall of the fixing rod, one end outer wall of the fixing rod is fixedly connected to a limit plate, and a fixing block is installed outside the fixing rod;

[0008] A driving groove and an installation groove are respectively provided inside the fixed block, two groups of symmetrical wedge blocks are installed on the inner wall of the driving groove, one end of the wedge block is fixedly connected to an insert block, and the inner wall of the installation groove is fixedly connected to a spring fixedly connected to a limit plate.

[0009] Preferably, one end of the guide rod is fixedly connected to the outer wall of the lower mold, and a ball is rollingly connected to the inner wall of the top end of the guide rod.

[0010] Preferably, one end of the guide hole is provided with a rounded corner, and the side of the guide hole provided with the rounded corner is rollingly connected to a ball bearing.

[0011] By adopting the above technical solution, the hydraulic cylinder is started to close the lower mold and the upper mold for injection molding. During the closing process, the guide rod is matched with the guide hole to ensure the accuracy of the closing and avoid deviation.

[0012] Preferably, the inner wall of the spherical block is fixedly connected to the outer wall of the fixing rod, and the fixing rod is slidably connected to the inner wall of the fixing block.

[0013] Preferably, an outer wall of one side of the wedge block is slidably connected to an outer wall of the spherical block, and sliders that limit sliding movement with the inner wall of the driving groove are fixedly connected to both sides of the wedge block.

[0014] Preferably, the outer wall of the plug block is plugged into the fixed block and the positioning hole in sequence, and the outer wall of the limit plate is slidably connected to the inner wall of the mounting groove.

[0015] By adopting the above technical solution, during the mold closing process, the fixing rod drives the outer fixing block to be inserted into the positioning frame, and then the mold is closed again so that the insert block at one end of the wedge block inside the fixing block is inserted into the positioning hole of the side wall of the positioning frame to complete the fixation, thereby ensuring the strength of the mold closing.

[0016] The beneficial effects of the utility model are:

[0017] Start the hydraulic cylinder to close the lower mold and the upper mold and then carry out injection molding. During the closing process, the fixed rod drives the outer fixed block to slowly insert into the positioning frame until the bottom end of the fixed block contacts the lower mold. At this time, continue to drive the hydraulic cylinder to close the mold downward. The limit plate at one end of the fixed rod squeezes the spring inside the fixed block. At the same time, the two spherical blocks above slide downward to cooperate with the inclined surface of the wedge block to make the insert block extend out of the fixed block and insert into the positioning hole on the positioning frame, thereby completing the fixation of the lower mold and the upper mold. When disassembling, you only need to drive the hydraulic cylinder upward to disengage the mold. The operation is simple and the efficiency of disassembly and assembly between molds is improved.

At this time, the hydraulic cylinder 3 continues to be driven to close the mold downward. The limit plate 12 at one end of the fixing rod 10 squeezes the spring 18 to slide inside the fixing block 13. At the same time, the two spherical blocks 11 above slide downward to cooperate with the inclined surface of the wedge block 16 to make the insert block 17 extend out of the fixing block 13 and insert into the positioning hole 7 on the positioning frame 6, thereby completing the fixation of the lower mold 1 and the upper mold 8.

During the closing process, the guide hole 9 opened on the upper mold 8 slowly passes through the guide rod 4. When the closing position is offset, the ball 5 set on the upper end of the guide rod 4 cooperates with the fillet opened on the inner and outer sides of the guide hole 9, and a rolling connection occurs between the two, so that the guide rod 4 and the guide hole 9 are adjusted to ensure the accuracy of the closing. During the closing process, the fixed rod 10 drives the outer fixed block 13 to slowly insert into the positioning frame 6 until the bottom end of the fixed block 13 contacts the lower mold 1. At this time, the hydraulic cylinder 3 is continued to be driven to close the mold downward. The limit plate 12 at one end of the fixed rod 10 squeezes the spring 18 to slide inside the fixed block 13.
