Referring to fig. 1 to 7, the present invention discloses a thermoforming apparatus comprising a frame 100, a forming assembly 200 and a cooling assembly 400.

The forming assembly 200 includes a first top mold 210 and a first bottom mold 220 disposed on the frame 100, the first top mold 210 and the first bottom mold 220 can be mutually fastened and respectively attached to two sides of the to-be-formed member 300, a heating element 230 for heating the to-be-formed member 300 is disposed on the forming assembly 200, the cooling assembly 400 includes a second top mold 410 and a second bottom mold 420 disposed on the frame 100, the second top mold 410 and the second bottom mold 420 can be mutually fastened and respectively attached to two sides of the to-be-formed member 300, and a cooling pipeline 430 for cooling the to-be-formed member 300 is disposed on the cooling assembly 400.

It can be understood that, during the processing, the to-be-formed member 300 is firstly placed on the forming assembly 200, and after the first top mold 210 and the first bottom mold 220 are fastened, the to-be-formed member 300 is pressed between the first top mold 210 and the first bottom mold 220 and is formed into a desired shape, in this process, the heating element 230 on the forming assembly 200 heats the to-be-formed member 300 to promote the deformation of the to-be-formed member 300; after the heated and molded member 300 is gradually deformed and deviates from the desired shape along with the decrease of the temperature, the member 300 is placed on the cooling assembly 400 for cooling, after the second top mold 410 and the second bottom mold 420 are fastened, the member 300 is pressed between the second top mold 410 and the second bottom mold 420 to keep the member 300 in the desired shape after being molded, and at the same time, the cooling pipeline 430 on the cooling assembly 400 can cool the member 300, so that the member 300 can be rapidly cooled and kept in the desired shape. According to the thermal forming device, the cooling assembly 400 is arranged, so that the to-be-formed part 300 can be rapidly cooled and shaped under the condition of keeping the required shape, the deformation of the to-be-formed part 300 after forming can be reduced, and the product quality and the appearance effect are improved.

Wherein, the two sides of the member to be formed 300 refer to the two sides of the sheet-like member to be formed 300 in the initial state. In addition, a protrusion may be disposed on the first top mold 210, a recess may be disposed on the first bottom mold 220, after the first top mold 210 and the second top mold 220 are fastened, the protrusion and the recess may be engaged with each other, and the shape of the protrusion may be the same as the required shape of the member 300 to be formed.

In the thermoforming apparatus of the present invention, if the cooling module 400 is not provided with the cooling pipeline 430, the cooling module 400 can only perform the function of pressing the member to be formed 300 to keep the member to be formed 300 in the desired shape, but does not perform the function of rapidly cooling the member to be formed 300, the heat on the member to be formed 300 is only continuously accumulated on the cooling module 400, and after a period of time, the temperature of the cooling module 400 may gradually increase to be the same as the temperature of the member to be formed 300, and the cooling module 400 cannot perform the cooling function. After the cooling pipe 430 is disposed on the cooling assembly 400, the cooling pipe 430 can continuously take away the temperature of the member to be formed 300, so that the cooling assembly 400 is always kept in a cooling state, and the cooling of the member to be formed 300 can be accelerated. Specifically, the cooling medium, such as water or cold air, flows through the cooling pipeline 430, and the heating element 230 may be a heat pipe.

Referring to fig. 1 to 3, in some embodiments of the present invention, a preheating assembly 500 is further included, and if the member 300 to be molded is directly placed on the molding assembly 200 for thermoforming, the processing efficiency is slow because the member 300 to be molded is sheet-shaped in an initial state, for example, if it takes a long time to heat the member 300 to a temperature at which the member 300 to be molded is easily deformed, the heating time of the member 300 to be molded on the molding assembly 200 can be shortened by providing the preheating assembly 500. Specifically, while the former to-be-formed part 300 is heated on the forming assembly 200, the latter to-be-formed part 300 can be simultaneously preheated on the preheating assembly 500, and so on.

Further, the preheating assembly 500 includes a third top mold 510 and a third bottom mold 520 disposed on the frame 100, the third top mold 510 and the third bottom mold 520 can be fastened to each other and respectively attached to two sides of the member to be formed 300, and a preheating member 530 for heating the member to be formed 300 is disposed on the preheating assembly 500.

In some embodiments of the present invention, the heating temperatures of the preheating member 530 and the heating member 230 are the same, so that the heating time of the member 300 to be formed can be distributed to the preheating assembly 500 and the forming assembly 200, the heating time can be shortened, and the forming efficiency can be improved.

In some embodiments of the present invention, the preheating member 530 is disposed on the third top mold 510, and the preheating member 520 is preferably disposed on a mold having protrusions, i.e., the third top mold 510 in this embodiment, the preheating member 530 only needs to preheat the to-be-formed member 300, and the preheating member 530 does not need to be disposed on both the third top mold 510 and the third bottom mold 520, which can save cost. The first top mold 210 and the first bottom mold 220 are both provided with heating members 230, so that the member 300 to be formed can be heated uniformly.

In some embodiments of the present invention, since there may be a portion of the to-be-formed part 300 that does not need to be deformed if the portion is heated to affect the final effect of the product, the heat insulating member 240 may be disposed on the first top mold 210, the heat insulating member 240 may abut against the portion of the to-be-formed part 300 when the first top mold 210 and the first bottom mold 220 are fastened to each other, the heat insulating member 240 may perform a heat insulating function, and the portion of the to-be-formed part 300 that does not need to be deformed may not need to contact too much heat.

As shown in fig. 2 and 5, in some embodiments of the present invention, the cooling pipes 430 are disposed on the second top mold 410 and the second bottom mold 420, so that both the upper and lower surfaces of the member to be molded 300 can be cooled by the cooling pipes 430.

Referring to fig. 6, in some embodiments of the present invention, a feeding device 600 is further included, the molding assembly 200 and the cooling assembly 400 are arranged in a left-right direction, the feeding device 600 is provided with two material trays 610 capable of holding the to-be-molded article 300, the two material trays 610 are arranged on the rack 100 in a front-back direction, and the feeding device 600 is movable in the front-back direction. Specifically, the manipulator or the like can be used for clamping the to-be-molded part 300 in one of the material containing trays 610 at the loading position for processing, and after the to-be-molded part 300 in the material containing tray 610 is processed, the loading device 600 can move in the front-back direction, so that the other material containing tray 600 is aligned to the loading position of the manipulator for continuing loading.

Further, referring to fig. 7, in some embodiments of the present invention, the robot may be replaced with a plurality of suction cups 700 that can suck the member to be molded 300, and in particular, the plurality of suction cups 700 may reciprocate between the molding assembly 200 and the cooling assembly 400. The plurality of suction cups 700 may also reciprocate between the preheating assembly 500, the molding assembly 200, and the cooling assembly 400 when the preheating assembly 500 is disposed on the frame 100.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
