Unless otherwise defined, all technical and scientific terms used in this document have the same meaning as those generally understood by technicians in the technical field of the present invention. It should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The terms used in this document in the specification of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A plaster mold heating device for uniform heating comprises a shell 1, a heating tube 2 is arranged on the inner wall of the shell 1, a sealing door 4 is rotatably connected to one side of the shell 1 through a hinge, an exhaust pipe 5 is connected to the top of the shell 1, and a solenoid valve 6 is arranged on the outer side of the exhaust pipe 5; a placement mechanism 3, the placement mechanism 3 comprises a support frame 31 arranged inside the shell 1, a connecting plate 32 is arranged on the inner wall of the support frame 31, a limiting groove 33 is arranged on the inner wall of the connecting plate 32, and a handle 34 is arranged on one side of the connecting plate 32.

[0022] In the specific implementation process, Figure 1-Figure 4 As shown, the placement mechanism 3 also includes a threaded hole 35 opened on the inner wall of the connecting plate 32 , and the inner wall of the support frame 31 is threadedly connected with a hand screw 36 , and the outer side of the hand screw 36 is threadedly connected to the inner wall of the threaded hole 35 .

[0023] The top of the support frame 31 is fixedly connected with a connecting shaft 7 , and the top of the connecting shaft 7 is rotatably connected to the top of the inner cavity of the housing 1 through a bearing seat.

[0024] A motor 8 is arranged at the bottom of the inner cavity of the housing 1 , the output end of the motor 8 is fixedly connected to the outer side of the driving wheel 9 , which is meshedly connected to the driven wheel 10 , and the inner ring of the driven wheel 10 is fixedly connected to the driving shaft 11 .

[0025] The top of the driving shaft 11 passes through the inner wall of the outer shell 1 and is fixedly connected to the bottom of the supporting frame 31 , and the bottom of the driving shaft 11 is rotatably connected to the bottom of the inner cavity of the outer shell 1 through a bearing seat.

[0026] It should be noted that: by setting up the placement mechanism 3, it is convenient to heat multiple plaster molds at the same time without causing deformation of the plaster molds, thereby improving practicality. When in use, the connecting plate 32 is taken out, and then the plaster mold in a semi-wet state is placed in the limiting groove 33, and it is fixed by the limiting groove 33 to prevent the plaster mold from being deformed by the support. There are two connecting plates 32 and eight limiting grooves 33, so that eight plaster molds can be heated at the same time, thereby improving work efficiency. Then the connecting plate 32 is installed in the support frame 31, and then the hand screw 36 is screwed in and penetrates the support frame 31 and the limiting groove 33. The threaded hole 35 on the inner wall of the connecting plate 32 is connected to fix the connecting plate 32, and the heating tube 2 is used to heat the inside of the shell 1. At this time, the motor 8 is started to make the driving wheel 9 drive the driven wheel 10 to rotate. When the driven wheel 10 rotates, it can drive the driving shaft 11 to rotate, so that the support frame 31 drives the connecting shaft 7 to rotate. The connecting shaft 7 can make the support frame 31 stable when rotating, and then the plaster mold can be rotated so that it can be heated evenly. After use, the solenoid valve 6 is started first to discharge the hot air in the shell 1 from the exhaust pipe 5 to avoid scalding people by the hot air when the user opens the sealing door 4 to take away the plaster mold.

[0027] The working principle of the uniformly heated plaster mold heating device provided by the utility model is as follows:

[0028] When in use, the connecting plate 32 is taken out, and then the gypsum mold is placed in the limiting groove 33, and then the connecting plate 32 is installed in the support frame 31, and then the hand screw 36 is screwed in and penetrates the threaded hole 35 on the inner wall of the support frame 31 and the connecting plate 32 to fix the connecting plate 32, and the heating tube 2 is used to heat the inside of the shell 1. At this time, the motor 8 is started to make the driving wheel 9 drive the driven wheel 10 to rotate. When the driven wheel 10 rotates, the driving shaft 11 can drive the support frame 31 to rotate, and then the gypsum mold can be rotated, so that it can be heated evenly.
