Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A mold heat treatment device includes a heat treatment mechanism and a feeding mechanism. The heat treatment mechanism includes a treatment chamber 1 and a lifting chamber 2. A feed inlet 3 is located at the bottom of one side of the treatment chamber 1. The feeding mechanism is located at the feed inlet 3 at the bottom of the treatment chamber 1. The lifting chamber 2 has an opening at its bottom and is located inside the treatment chamber 1. A gantry frame 4 is fixed to the top of the treatment chamber 1, and a crane 5 is mounted on the gantry frame 4. A traction rope 6 connects the crane 5 and the lifting chamber 2. A heat insulation layer 7 is fixed to the inner wall of the lifting chamber 2, and a [missing information - likely a design feature or feature] is provided on the heat insulation layer 7. The heating wire 8 is provided. A cooling water tank 9 is provided at the upper position inside the processing chamber 1. Two inlet and outlet water pipes 10 are provided on the processing chamber 1 and are connected to the cooling water tank 9. The feeding mechanism includes a movable base 11. A heat insulation platform 12 is fixed at the top of the movable base 11. The heat insulation platform 12 and the heat insulation layer 7 are made of the same material. Four rollers 13 are rotatably connected to the bottom of the movable base 11. A dual-axis motor 14 is installed at the bottom of the movable base 11. The dual-axis motor 14 is located between two of the rollers 13. The two output ends of the dual-axis motor 14 are fixed to the rollers 13 on the same side, respectively.

[0023] In operation, external cold water is injected into the cooling water tank 9 through the inlet and outlet pipes 10, ensuring water flow. The control box 17 starts the dual-axis motor 14, which drives two rollers 13 to rotate. Under the action of the rollers 13, the moving chassis moves out of the processing chamber 1 at the feed inlet 3. The mold to be heat-treated is placed on the heat insulation table 12. The dual-axis motor 14 is started again, causing the moving chassis to move the mold to the inside of the processing chamber 1. The crane 5 is a mature existing technology that can raise and lower the traction rope 6. The traction rope 6 pulls the lifting chamber 2 upward, and the crane 5 is started to lower the traction rope 6. Under the action of gravity, the lifting chamber 2 moves downward along the inner wall of the processing chamber 1. The lifting chamber 2 moves the heat insulation layer 7 and the heating wire 8 downward, so that the protrusions on the heat insulation layer 7 match the grooves 16 on the heat insulation table 12, realizing the connection between the heat insulation layer 7 and the heating wire 8. When the heating platform 12 is closed, the mold is in a closed space. The heating wire 8 is activated to raise the temperature and perform heat treatment on the mold. After the treatment is completed, the crane 5 is activated to rewind the traction rope 6, which pulls the lifting chamber 2 upward so that the bottom of the lifting chamber 2 is higher than the discharge port. The heated air rises in temperature. Since the density of hot air is low, it will float upward. Under the restriction of the lifting chamber 2 and the treatment chamber 1, the hot air will not float out at the discharge port. When there is too much hot air, it will float upward through the gap between the lifting chamber 2 and the treatment chamber 1 and come into contact with the inner wall of the treatment chamber 1 at the position of the cooling water tank 9. Under the action of cold water, the heat exchange between the hot air, the inner wall of the treatment chamber 1 and the cold water is achieved, which achieves the effect of cooling the hot air that is about to be dispersed into the environment. Then the dual-axis motor 14 is activated to send the treated mold out of the moving base 11.

[0024] In actual use, it was found that misalignment between the heat insulation layer 7 and the heat insulation platform 12 would cause gaps, affecting heat treatment. To avoid the above problems, in this embodiment, four protrusions 15 are evenly provided at the bottom of the heat insulation layer 7, and multiple grooves 16 that are adapted to the protrusions 15 are provided at the top of the heat insulation platform 12.

[0025] In actual use, it was found that in order to facilitate centralized control of the crane 5, heating wire 8 and dual-axis motor 14, in this embodiment, a control box 17 is provided on the side wall of the processing chamber 1, and the crane 5, heating wire 8 and dual-axis motor 14 are all electrically connected to the control box 17.

[0026] In actual use, it was found that the lifting chamber 2 would wear against the inner wall of the processing chamber 1 when it moved up and down. In order to alleviate the above problem, in this embodiment, a plurality of rotating wheels 18 are rotatably connected to the outer wall of the lifting chamber 2, and the rotating wheels 18 are in contact with the inner wall of the processing chamber 1.

[0027] In actual use, it was found that in order to increase the contact area between hot air and the inner wall of the processing chamber 1, in this embodiment, a plurality of recessed grooves 19 are provided on the inner wall of the processing chamber 1 at the location of the cooling water tank 9.
