[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] In one embodiment, Figure 1-Figure 7 As shown, a mold preheating device that can be automatically clamped includes a preheating box 1 and a door panel 102 opened on the side of the preheating box, an observation window 103 is arranged on the surface of the door panel 101, an air outlet 102 is opened on the top of the preheating box 1, a heating tube 2 is fixedly connected to the inside of the preheating box 1, the heating tube 2 is arranged in a bent shape to increase the heating area, a first motor 3 is arranged at the middle position of the top of the preheating box 1 and a rotating shaft 301 is connected to the output end of the first motor 3, the rotating shaft 301 is rotatably connected to the preheating box 1 through a bearing and is connected to a connecting plate 302, and the connecting plate 302 is connected to an automatic clamping component, when the first motor 3 is started, the automatic clamping component can be driven to rotate, so that the preheating is more uniform.

[0028] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the automatic clamping assembly includes a slide groove 303, a slider 304, a return spring 305, a connecting rod 306 and a bottom plate 307. The slide groove 303 is provided with four groups and is evenly distributed in the connecting plate 302. The slide groove 303 is slidably connected to the slider 304. The slider 304 is connected to the inner wall of the slide groove 303 through the return spring 305. The vertical section of the slide groove 303 is "T" shaped and the slider 304 is adapted to the slide groove 303. The slider 304 is rotatably connected to the bottom plate 307 through the connecting rod 306. When the mold is placed on the bottom plate 307, the mold will be The force drives the bottom plate 307 to move downward. Since the slider 304 is limited by the slide groove 303 and the two ends of the connecting rod 306 are rotatably connected to the bottom plate 307 and the slider 304, the downward movement of the bottom plate 307 will drive the connecting rod 306 to rotate, and the rotation of the connecting rod 306 can drive the slider 304 to slide in the slide groove 303 until the front end of the slider 304 contacts the mold. At this time, the slider 304 cannot move further and the mold also stops moving downward. The slider 304 completes the clamping and fixing of the mold. The bottom plate 307 is made of aluminum alloy and is hollowed out to facilitate heat dissipation.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, a dustproof net 403 is provided on the side of the preheating box 1 close to the heating tube 2, and a fixing frame 4 is fixedly connected to the side of the preheating box 1 away from the dustproof net 403. The fixing frame 4 is connected to a second motor 401 and a fan 402 is connected to the output end of the second motor 401. When the second motor 401 is started, the fan 402 rotates to blow the hot air generated by the heating tube 2 into the preheating box 1.

[0030] The above embodiment discloses a mold preheating device that can be automatically clamped, wherein the door panel 101 is opened to place the molds onto the bottom plate 307 through the connecting plate 302 in sequence. Because the weight of the molds themselves drives the bottom plate 307 to move downward, during this process, the slider 304 is simultaneously driven to slide until the slider 304 clamps the mold. At the same time, the fan 402 blows the hot air generated by the heating tube 2 into the preheating box 1. Under the action of the first motor 3, the mold is rotated to complete uniform preheating.

[0031] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
