[0015] The present invention provides a hot pressing forming device for automobile interior decoration parts, which has the following beneficial effects:

[0016] When the present invention is in use, when the thermoplastic sheet is placed on the top of the main body, its bottom side contacts the top side of the forming lower die, the limiting frame is rotated and buckled to make it contact with the top edge of the thermoplastic sheet, thereby clamping and fixing the thermoplastic sheet, and the heater can be pulled forward to move it above the thermoplastic sheet for heating. After the thermoplastic sheet is softened, the heater moves backward and resets, and the forming equipment drives the forming upper die to move downward, so that the forming upper die and the forming lower die are merged together, and the thermoplastic sheet is hot-pressed to form, thereby finally achieving the forming effect of automobile interior decoration parts.

[0017] In addition, the rotation angle of the rotating part can be limited by the sliding cooperation between the limit column and the arc hole. When the limit frame contacts the top edge of the thermoplastic sheet, under the tension of the tension spring, the rotating part will automatically reset and drive the hook to rotate through the transmission rod, so that the top of the two hooks are connected to the limit frame, thereby automatically fixing the limit frame to ensure its effective clamping of the thermoplastic sheet. After the thermoplastic sheet is cooled and formed, it is only necessary to rotate the rotating part through the handle, and then drive the hook to rotate through the transmission rod to make its top detach from the limit frame. Then the limit frame can be easily lifted and the formed thermoplastic sheet can be taken out.

[0018] In addition, when the upper and lower molding dies are closed, the circulating pump delivers the low-temperature coolant in the heat sink into the guide channel through the delivery pipe. When the coolant flows in the guide channel, the lower molding die is cooled, thereby shortening the cooling and curing time of the thermoplastic sheet and improving the production efficiency of automotive interior parts. The heated coolant returns to the heat sink through the reflux pipe. At the same time, the exhaust fan inhales external air from the air inlet to the rear mounting groove, enhancing the air circulation around the heat sink and accelerating the process of heat dissipation into the air, ensuring the effective cooling of the coolant and further ensuring its good cooling effect on the lower molding die. The funnel-shaped design of the air inlet can reduce the temperature of the passing air and play an auxiliary cooling effect.

[0019] In addition, when the molding lower mold needs to be replaced according to the different automobile interior parts, the plug is first separated from the delivery pipe, so that the coolant in the guide channel is discharged through the drain pipe outlet and recycled. After the replacement of the molding lower mold is completed, the sealing ring contacts the assembly groove, and the sealing ring ensures the sealing between the guide channel and the guide pipe hole. Then the plug is reconnected to the drain pipe outlet, and then coolant is injected into the guide channel through the liquid inlet funnel to restore the normal circulation of the coolant, thereby better meeting the actual use needs.

[0020] In addition, when the molding lower mold is installed in the assembly groove, the vertical rod is inserted into the lock, the block is at the top of the lock, and the lock is rotated to stagger the block and the guide groove. At this time, the bottom side of the block contacts the top of the lock, and the lock fixes the molding lower mold, making the replacement and fixation of the molding lower mold faster and easier. The spring applies thrust to the lock to increase the rotation resistance of the lock and ensure the stability of the lock state.

[0021] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
