DETAILED DESCRIPTION

[0016] The following is combined with Figure 1-3 This application is described in further detail.

[0017] The embodiment of the present application discloses a cooling and shaping mold for the production of plastic products, including a die 1 and a punch 2. When the die 1 and the punch 2 are combined, a cavity 3 is formed. A cooling water channel 6 is provided in the die 1. Vertical grooves 10 are provided at the bottom of the cooling water channel 6. A water guide groove 8 is provided in the die 1. The lower ends of the vertical grooves 10 are connected to the water guide groove 8. The coolant in the puddles of the cooling water channel 6 can be discharged through the vertical grooves 10 and the water guide grooves 8. A sealing member is provided inside the vertical grooves 10 for controlling the on and off of the vertical grooves 10.

[0018] Furthermore, the wall thickness formed between the cooling water channel 6 and each part of the cavity 3 is equal, ensuring uniform heat exchange between each part of the plastic product and the coolant, resulting in a good cooling effect.

[0019] Furthermore, a water inlet trough 4 is provided on one side of the cooling water channel 6. The water inlet port of the water inlet trough 4 is connected to an inlet pipe 13 via a flange. The inlet pipe 13 is connected to an external pump. A water outlet trough 5 is provided on the other side of the cooling water channel 6. The water outlet port of the water outlet trough 5 is connected to an outlet pipe 14 via a flange. The outlet pipe 14 is connected to an external circulation pipeline. Specifically, the pump and circulation pipeline can be conventional pumps and water delivery pipelines. The principles of infusion involved are all conventional technologies and will not be elaborated here.

[0020] In this embodiment, a pump is used to transport the external coolant through the water inlet pipe 13 and the water inlet trough 4 to the inside of the cooling water channel 6. Under the action of the pump delivery pressure, the cooling water channel 6 will be discharged into the external circulation pipeline through the water outlet trough 5 and the water outlet pipe 14. During the circulation of the coolant, heat exchange can be generated with the plastic product inside the cavity 3, thereby accelerating the cooling of the plastic product.

[0021] Furthermore, the blocking parts include a blocking block 11 and a through groove 12. A cylindrical groove is provided in the middle of the vertical groove 10. The shape of the blocking block 11 matches the cylindrical groove and is installed inside the cylindrical groove to form a cylindrical moving pair inside the cylindrical groove. The through groove 12 is located on the blocking block 11 and is perpendicular to the central axis of the blocking block 11. The diameter of the through groove 12 is equal to that of the vertical groove 10.

[0022] Furthermore, the blocks 11 are connected by a rotating rod 9 , and the rotating rod 9 is located on the central axis of the block 11 . A motor 7 is fixedly mounted on the surface of the die 1 , and a power end of the motor 7 is fixedly connected to one end of the rotating rod 9 .

[0023] During actual use, a corresponding sealing component may be further provided on the surface of the blocking block 11 , such as a corresponding rubber sealing ring on the surface of the blocking block 11 , to ensure the sealing performance of the blocking block 11 when sealing the vertical groove 10 .

[0024] In this embodiment, the driving motor 7 is driven to rotate, thereby driving the rotating rod 9 and the blocking block 11 to rotate, so that the relative position of the through groove 12 and the vertical groove 10 can be adjusted. In this embodiment, when the through groove 12 and the vertical groove 10 are misaligned, the vertical groove 10 remains in a closed state. In this state, cooling work can be carried out, that is, the coolant is transported to the inside of the cooling water channel 6 by a pump or the like to accelerate the cooling of the plastic product; when the through groove 12 is aligned with the vertical groove 10, the vertical groove 10 remains in an open state, and since the vertical groove 10 is set at the bottom of the cooling water channel 6, the cooling water channel 6 can be smoothly discharged through the vertical groove 10 and the water guide groove 8. In actual use, the number and position of the vertical grooves 10 should be set according to the shape of the cooling water channel 6, that is, they should be set according to the low-lying part of the cooling water channel 6 to ensure that the coolant in the cooling water channel 6 can be completely discharged.
