[0030] Working principle: the dashboard trim aluminum sheet is made of metal aluminum and is usually installed on the car dashboard or other equipment for decoration to improve its appearance and aesthetics. The production and processing of the aluminum sheet requires the use of a forming mold to stamp the aluminum sheet. The existing forming mold uses resin materials, which are more worn during the stamping process, and the aluminum sheet after extrusion is easy to adhere to the inside of the resin mold, which is not convenient for demolding, resulting in a decrease in the processing efficiency of the aluminum sheet. In order to solve this problem, a demolding mechanism and an auxiliary mechanism are set to place the workpiece inside the lower mold 2 and control the hydraulic cylinder. 15 contracts the inner hydraulic rod 16, thereby pulling the upper mold 18 down accurately in the vertical direction through the support plate 17, so that the upper mold 18 is buckled on the top side of the lower mold 2. During the descending process of the upper mold 18, the positioning block 23 is driven to descend in the vertical direction. When the positioning block 23 moves to the top side of the slide groove 19, the inclined surface of the positioning block 23 contacts the inclined surface of the trapezoidal holder 21. At this time, the positioning block 23 pushes the trapezoidal holder 21 to slide on the top side of the slide groove 19, thereby driving the push block 20 to slide inwardly of the slide groove 19 and compressing the second spring 22. At this time, the push block 20 contracts to the lower mold 2 The inner slide groove 19 is in the same plane as the inner surface of the lower mold 2. At this time, the upper mold 18 is tightly fitted with the lower mold 2. The positioning block 23 is inserted and installed on the top side of the slide groove 19 to prevent the push block 20 from affecting the stamping process, thereby stamping the workpiece. After that, the hydraulic cylinder 15 is controlled to drive the upper mold 18 to rise. At this time, the servo motor 8 is controlled to drive the output end screw 7 to rotate, thereby driving the lower molds 2 on both sides through the connecting seat 3. With the cooperation of the sliding seat 4, they slide to both sides on the sliding rod 6 and separate. At this time, the second spring 22 pushes the push block 20 under the action of its own elastic force. It extends out from the inner side of the slide slot 19, thereby pushing the workpiece that has completed the stamping process out of the lower mold 2. At the same time, under the action of the elastic force of the first spring 12, the limit seat 10 is pulled to slide upward on the limit rod 9, thereby driving the trapezoidal push plate 11 to move upward, making it contact with the aluminum sheet and ejecting it from the inner side of the lower mold 2, so as to facilitate the removal of the workpiece. When processing again, the servo motor 8 is controlled in the same way to merge the lower molds 2 on both sides, and push the inclined surfaces on both sides of the trapezoidal push plate 11 to make it drop and reset, so as to carry out the next processing, which solves the problem that the existing molding mold is more worn and inconvenient to demould.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
