[0016] (1) The rapid prototyping injection mold for transparent parts of vehicle lamps described in the present invention comprises a supporting mechanism, on which an auxiliary mechanism is slidably mounted. The supporting mechanism and the auxiliary mechanism are arranged to provide placement space for two groups of injection molding components, and the structure is simple and clear at a glance, which is convenient for later maintenance, namely: two groups of slide plates are provided for driving the mold to perform injection molding operations, which is convenient for improving injection molding efficiency.

When the support plate and the slide plate are close to each other, the two stripping plates no longer occupy the space of the mold, but instead fit against the inner wall of the mold, leaving space in the mold for injection molding. When the limit plate is active, the pushing block pushes the sealing plate to slide, so that the sealing plate no longer seals the channel between the telescopic tube and the docking port. The third spring drives the telescopic tube to move to the bottom end by pushing the limit ring, thereby facilitating the connection of the telescopic tube to the docking port, so that the feed tube and the interior of the mold are connected, which facilitates the entry of materials into the mold for molding. When the limit plate is reset to the initial position, the pushing block no longer pushes the sealing plate, so that the docking port and the telescopic tube are no longer connected, avoiding material overflow and waste. When the slide plate is reset, the stripping plate pushes the molded plastic parts inside the mold, so that the plastic parts are separated from the mold and fall into the cooling pool for cooling. The automated injection molding and cooling process avoids human intervention and greatly improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The two groups slide together on the common sliding shaft 12 to improve space utilization. A first spring 22 is sleeved on the sliding shaft 12, and the first spring 22 resists the slide plate 21, which is convenient for driving the slide plate 21 to automatically reset. The multiple sliding shafts 12 are assembled with the supporting plate 11 through the threaded bolts 12 and the nuts 15, and the supporting plate 11 and the sliding shaft 12 are placed horizontally, which reduces the height of the device, thereby avoiding maintenance personnel from climbing to a high place for maintenance, and facilitating maintenance.

[0032] like Figures 1 to 7 As shown, the opening and closing mechanism 4 includes a limit plate 41, the limit plate 41 is connected to the telescopic rod 24, the telescopic rod 24 drives the limit plate 41, the limit plate 41 is provided with a limit groove 42, the limit protrusion 43 is fixed on the slide plate 21, and the limit protrusion 43 slides with the limit plate 41 through the limit groove 42. The support plate 11 is fixedly connected to the fixed plate 44, the fixed plate 44 is connected to a connecting shaft 45, the connecting shaft 45 slides with the slide plate 21, the slide plate 21 is connected to a mold 46, a stripper plate 47 slides in the mold 46, the stripper plate 47 is fixedly connected to the connecting shaft 45, a second spring 48 is wound around the connecting shaft 45, and the second spring 48 abuts against the stripper plate 47 and the slide plate 21.

[0033] like Figures 1 to 7As shown, the injection mechanism 5 includes a feed pipe 51, the feed pipe 51 is connected to the slide plate 21, the mold 46 is connected to a docking port 56, a sealing plate 55 is provided on the docking port 56, the sealing plate 55 slidably cooperates with the slide plate 21, a fourth spring 57 is in contact with the sealing plate 55 and the slide plate 21, a push block 58 is in contact with the sealing plate 55, and the push block 58 is fixedly connected to the slide plate 21.

When performing the injection molding operation, the telescopic rod 24 is first started, and the telescopic rod 24 drives the limit plate 41 to move. The limit plate 41 slides with the limit protrusion 43 through the inclined limit groove 42. The limit protrusion 43 is fixedly connected to the slide plate 21, and can drive the two slide plates 21 to move closer to each other, so that the two molds 46 are close to each other and engage with each other, so that the two molds 46 form a closed space. The stripping plate 47 is fixedly connected to the supporting plate 11 through the connecting shaft 45. When the slide plate 21 moves closer, the two stripping plates 47 no longer occupy the space of the mold 46, but instead fit to the inner wall of the mold 46, leaving the space of the mold 46 for the injection molding operation. When the limit plate 41 is active, the pushing block 58 pushes the sealing plate 55 to slide, so that the sealing plate 55 is no longer in the close space. The passage between the telescopic tube 52 and the docking port 56 is sealed, and the third spring 54 drives the telescopic tube 52 to move toward the bottom by pushing the limiting ring 53, so that the telescopic tube 52 is connected to the docking port 56, so that the feeding tube 51 and the interior of the mold 46 are connected, which facilitates the material to enter the mold 46 for molding. When the limiting plate 41 is reset to the initial position, the pushing block 58 no longer pushes the sealing plate 55, so that the docking port 56 and the telescopic tube 52 are no longer connected, thereby avoiding material overflow and waste. When the slide plate 21 is reset, the stripping plate 47 pushes the molded plastic parts inside the mold 46, so that the plastic parts are separated from the mold 46 and fall into the cooling pool 32 for cooling.

The rolling roller 35 drives the conveyor belt 36 to rotate counterclockwise, thereby facilitating the transportation of the high-temperature injection molded parts dropped from the top to the deeper water level position of the cooling pool 32, so that the injection molded parts can be quickly and fully cooled, and the injection molded parts can be pushed to a position close to the rotating drum 33. The rotating rotating drum 33 drives the grid plate 34 to rotate counterclockwise, thereby facilitating the transfer of the cooled injection molded parts to the interior of the drying trough 31, facilitating the drying and collection of the injection molded parts, avoiding manual operation, and improving the efficiency of the tail processing of the injection molded parts.

[0036] When the present invention is in use, two groups of slide plates 21 are provided for driving the mold 46 for injection molding, thereby facilitating the improvement of injection molding efficiency. The two groups slide together and cooperate on the common slide shaft 12 to improve space utilization.

The stripper plate 47 is fixedly connected to the supporting plate 11 through the connecting shaft 45. When the slide plate 21 moves closer, the two stripper plates 47 no longer occupy the space of the mold 46, but instead fit to the inner wall of the mold 46, leaving the space of the mold 46 for the injection molding operation. When the limit plate 41 is active, the push block 58 pushes the sealing plate 55 to slide, so that the sealing plate 55 no longer seals the telescopic rod 24, and the push block 58 pushes the sealing plate 55 to slide. The passage between the expansion tube 52 and the docking port 56, the third spring 54 drives the expansion tube 52 to move to the bottom end by pushing the limit ring 53, thereby facilitating the expansion tube 52 to be connected to the docking port 56, so that the inside of the feed tube 51 and the mold 46 are connected, which facilitates the material to enter the mold 46 for molding. When the limit plate 41 is reset to the initial position, the push block 58 no longer pushes the sealing plate 55, so that the docking port 56 and the expansion tube 52 are no longer connected, avoiding material overflow and waste. When the slide plate 21 is reset, the stripper plate 47 pushes the molded plastic parts inside the mold 46, so that the plastic parts are separated from the mold 46 and fall into the cooling pool 32 for cooling. The automated injection molding separation cooling process avoids human intervention and greatly improves the production efficiency.
