[0018] The following is a further detailed description through specific implementation methods:

[0019] like Figures 1 to 3 As shown:

[0020] A mold heating device comprises a support frame, an airflow module and a heating module, wherein the airflow module and the heating module are both mounted on the support frame, the support frame is used to wrap the heating module and the airflow module, so that the support frame can block the side of the heating module, so that the heat of the heating module can be directed to the upper and lower sides thereof, the heating module is used for heating and temperature increase, and the airflow module can generate a flowing airflow, so that the flowing airflow can conduct the heat generated at the heating module to the upper and lower sides of the device;

[0021] The heating module includes a heating mechanism and a heat-conducting mechanism. The heat-conducting mechanism is installed on the inner side of the heating mechanism and the heat-conducting mechanism is connected with the heating mechanism, so that after the heating mechanism generates heat, the heat is conducted to the mold through the heat-conducting module; the heating mechanism includes a heating main pipe 6 in a "mouth"-shaped closed-loop structure, and a heating wire 9 installed in the heating main pipe 6; the heat-conducting mechanism is a plurality of heating branch pipes 7, and the heating branch pipe 7 is fixedly installed on the inner side of the heating main pipe 6, so that the heating main pipe 6 and the heating branch pipe 7 are connected, so that the heat generated at the heating main pipe 6 can flow to the heating branch pipe 7, and the upper and lower sides of the heating branch pipe 7 are provided with a plurality of air outlets 8, so that the hot air flow in the heating branch pipe 7 can be discharged to the upper and lower sides of the device through the air outlets 8.

[0022] The support frame includes a handle 1 and an outer frame 5. The handle 1 is fixedly installed on one side of the outer frame 5 so that the user can hold the handle 1 to operate the device. The handle 1 is a tubular structure. The handle 1 is connected to the heating pipe 6 installed on the inner side of the outer frame 5. The width of the outer frame 5 is equal to the diameter of the heating pipe 6, so that both ends of the outer frame 5 are raised on the upper and lower sides of the heating pipe 6, thereby forming a guide plate of the heating module, so that the heat emitted by the heating module is dissipated toward the upper and lower sides of the device.

[0023] The handle 1 is provided with a mounting compartment 4 , and an airflow module is mounted at the mounting compartment 4 . The airflow module is a blower 10 , and the blower 10 can generate a flowing airflow to be input into the heating main pipe 6 .

[0025] The surface of the handle 1 is provided with anti-skid patterns 3, which makes the user more comfortable to hold the handle 1 and has an anti-skid effect.

[0026] The specific implementation process is as follows:

[0027] Many molds have two parts, upper mold and lower mold, so the device can heat and increase the temperature of the upper mold and the lower mold of the mold at the same time; when using the mold heating device, first separate the upper mold and the lower mold of the mold, place the device between the upper mold and the lower mold, and then pneumatically operate the device, the blower 10 is started, the blower 10 can transport the outside air to the heating main pipe 6 through the air inlet 2 at the handle 1, and the heating wire 9 in the heating main pipe 6 works to heat the air in the heating main pipe 6, thereby generating a hot air flow, and the hot air flow enters the heating branch pipe 7, and is discharged from the air outlet 8 on the upper and lower sides of the heating branch pipe 7 to the upper and lower sides of the device, thereby heating the upper mold and the lower mold on the upper and lower sides of the device, effectively improving the heating uniformity of the mold and effectively avoiding excessive heating of the mold, meeting the user's usage needs.

[0028] The mold heating device generates high-temperature air through a heating module, and at the same time forms a heated airflow through an airflow module. The heated airflow is sprayed onto the mold to heat the mold. The device can heat the mold evenly to avoid uneven heating temperature in different parts of the mold, and can effectively avoid excessive heating of the mold and reduce the possibility of damage to the mold during heating.
