Technical Field

[0001] This utility model relates to the field of plastic molding technology, and in particular to a plastic container molding die. Background Technology

[0002] A container is a basic device used to hold materials and is primarily composed of a shell. Plastic containers are made of plastic using a hollow molding process. In the production of plastic containers, molding dies are used. However, with existing methods, after the mold is opened following molding, the finished product cannot be directly removed from the mold due to overheating, reducing production efficiency. To address this problem, we propose a new plastic container molding die. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a plastic container molding mold.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a plastic container molding mold, comprising a base plate and an upper plate, wherein a lower mold is fixedly connected to the upper end of the base plate, and an upper mold is fixedly connected to the lower end of the upper plate; four sets of retraction rods are arranged between the base plate and the upper plate, and the four sets of retraction rods are respectively arranged at the four corners of the base plate; cooling components are arranged on both sides of the base plate; the cooling components include a housing, and rotating rods are rotatably connected to both the upper and lower ends of the housing; and a fan is arranged on the inner side of the housing.

[0005] Preferably, the upper and lower ends of the housing are fixedly connected to a second rotating plate, the two sets of rotating rods are rotatably connected to the two sets of second rotating plates respectively, one end of the rotating rod is rotatably connected to a first rotating plate, the two sets of first rotating plates are fixedly connected to the upper mold and the lower mold respectively, and the first rotating plate and the second rotating plate are both U-shaped.

[0006] Preferably, the front and rear ends of the housing are provided with sliding grooves, and two sets of baffles are slidably connected to the inner sides of the two sets of sliding grooves. Two sets of connecting blocks are fixedly connected to the front end of the baffles. A connecting rod is rotatably connected to the inner side of the connecting block. A third rotating plate is fixedly connected to the other end of the connecting rod. The third rotating plate is rotatably connected to the rotating rod. The third rotating plate is U-shaped.

[0007] Preferably, one set of the two sets of baffles has an insert fixedly connected to its upper end, and the other set of the two sets of baffles has a slot at its lower end, with the insert fitting into the slot.

[0008] Preferably, a mounting plate is fixedly connected to the inner side of the housing, a fan is fixedly connected to the inner side of the mounting plate, and a filter screen is fixedly connected to the inner side of the housing away from the baffle.

[0009] Preferably, a pressure switch is fixedly connected to the upper end of the housing, and a pressure strip is fixedly connected to the upper end of the baffle near the upper end. The pressure strip is arc-shaped and fits against the pressure switch.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This plastic container molding die uses a retractable rod to lift the upper plate upwards, facilitating the separation of the upper and lower molds. At this time, a rotating rod follows the upper mold, rotating inside the first rotating plate and causing the shell to move closer to the lower and upper molds. This allows a fan to cool the molded plastic container. Simultaneously, the rotating rod drives the connecting blocks to rotate, causing the connecting rods to rotate inside the two sets of connecting blocks. The two sets of connecting rods then pull two sets of baffles to slide inside the sliding grooves, opening the shell. The two sets of baffles can then close the shell, preventing dust from entering. The upper baffle also drives a pressure strip to activate a pressure switch, starting the fan to blow air onto the mold. A filter screen filters the air to prevent dust from falling onto the newly molded plastic bottle. This invention can cool the plastic container and allows the fan to start and stop with the opening and closing of the lower and upper molds, facilitating cooling and reducing energy waste.

[0016] Specifically, the rotating rod 62 will rotate with the upper mold 4 inside the first rotating plate 65, and drive the shell 61 to move closer to the lower mold 3 and the upper mold 4, so that the fan 611 can cool the molded plastic container.

[0017] In this embodiment, both the front and rear ends of the housing 61 are provided with sliding grooves 63. Two sets of baffles 64 are slidably connected to the inner sides of the two sets of sliding grooves 63. Two sets of connecting blocks 67 are fixedly connected to the front end of the baffles 64. A connecting rod 68 is rotatably connected to the inner side of the connecting block 67. A third rotating plate 69 is fixedly connected to the other end of the connecting rod 68. The third rotating plate 69 is rotatably connected to the rotating rod 62. The third rotating plate 69 is U-shaped.

[0018] Specifically, the rotating rod 62 will drive the connecting block 67 to rotate, and drive the connecting rod 68 to rotate inside the two sets of connecting blocks 67. At the same time, the two sets of connecting rods 68 will pull the two sets of baffles 64 to slide inside the slide groove 63, so that the housing 61 can be opened. The two sets of baffles 64 can close the housing 61 to prevent dust from entering the inside of the housing 61.

[0019] In this embodiment, an insert 615 is fixedly connected to the upper end of one set of two sets of baffles 64, and a slot 616 is opened at the lower end of the other set of two sets of baffles 64, with the insert 615 fitting into the slot 616.

[0020] Specifically, the insert 615 and the bayonet 616 facilitate the connection between the two sets of baffles 64, allowing the two sets of baffles 64 to fit together tightly.
