DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Reference Figure 1-Figure 2 The utility model provides an embodiment: a floating molding trimming mold for automobile interior processing, including a floating frame 1, a hydraulic cylinder 2 is arranged on the upper end of the floating frame 1, and an upper mold 3 is fixedly connected to the bottom output end of the hydraulic cylinder 2, a lower mold 4 is arranged inside the floating frame 1, and an annular groove 5 is opened on the outer surface of the upper mold 3. The above-mentioned floating frame 1 includes: a base, a column, a limit frame, a spring, an air guide tube and a plunger tube, etc. Through the cooperation of the plunger tube, an air guide tube and a piston and other structures, when the upper mold 3 moves downward, the lower mold 4 moves up under the action of pneumatic push, thereby improving the pressing effect, and at the same time, it is convenient to carry out the separation operation after the pressing is completed, so as to realize the floating pressing molding operation. The above-mentioned floating frame 1 is similar to the floating molding mold principle mentioned in the Chinese patent with announcement number CN215203038U (a floating molding trimming mold for automobile interior), and the same effect is achieved. It is an existing technical means in this field and will not be described in detail here. A trimming component is arranged on the outer side of the upper mold 3.

[0036] Reference Figure 2-Figure 3 The trimming assembly includes: a motor 601 and a fixed plate 604. The motor 601 is fixedly connected to the upper surface of the upper mold 3. The bottom output end of the motor 601 passes through the upper surface of the upper mold 3. The bottom output end of the motor 601 is fixedly connected to a gear 602. The internal rotation of the annular groove 5 is connected to a gear ring 603. The gear 602 is located inside the annular groove 5. The tooth surface of the gear 602 is meshed with the internal tooth surface of the gear ring 603. When the motor 601 is started, the gear 602 can be driven to rotate. At this time, the gear 602 can drive the gear ring 603 to rotate. The fixed plate 604 is fixedly connected to the left surface of the gear ring 603. When the gear ring 603 rotates, the fixed plate 604 can be driven to revolve around the upper mold 3. The bottom surface of the fixed plate 604 is fixedly connected to a cutter 605. When the fixed plate 604 rotates, the cutter 605 can be driven to move synchronously, so that the cutter 605 performs trimming processing on the edge of the product, which can improve the trimming efficiency of the product.

[0037] The rear end of the bottom surface of the fixed plate 604 is fixedly connected with an elastic member 606, and the bottom end of the elastic member 606 is fixedly connected with a mounting frame 607. The mounting frame 607 is internally rotatably connected with a pressing roller 608. When the upper mold 3 moves downward to press the product, the pressing roller 608 will fit with the upper surface of the product, and move upward relative to the cutter 605 to squeeze the elastic member 606, so that the elastic member 606 is compressed to generate elastic potential energy. The elastic potential energy of the elastic member 606 squeezes the pressing roller 608 so that the bottom end of the pressing roller 608 is closely fitted with the surface of the product. As the fixed plate 604 rotates and drives the cutter 605 to rotate counterclockwise to trim the product, the pressing roller 608 will follow the rotation in the clockwise direction, and the product is lightly pressed by the friction between the pressing roller 608 and the product. A slight pull in the opposite direction of the trimming direction can prevent the product from being wrinkled in the trimming direction due to the pressure of the cutter 605 during the trimming operation, which will affect the molding effect of the product. The top of the fixed plate 604 is rotatably connected with a bolt 609, and the outer side of the bolt 609 is threadedly connected with a U-shaped frame 610. The bottom end of the U-shaped frame 610 passes through the fixed plate 604. Before the product is trimmed, the bolt 609 can be rotated to drive the U-shaped frame 610 to move downward under the limit of the fixed plate 604, so that the two ends of the bottom of the U-shaped frame 610 are in contact with the surface of the product without forming any extrusion. As the trimming proceeds, the bottom end of the U-shaped frame 610 can grind the edge of the product, and polish away the burrs generated at the trimming of some soft plastic automotive interiors, thereby improving the quality of the product.

[0038] Reference Figure 1-Figure 6, a slitting groove is provided on the upper surface of the lower mold 4, and the slitting groove can prevent the cutting knife 605 from piercing the product and contacting the lower mold 4 to cause damage when cutting the edge. The front end of the lower mold 4 is detachably connected with a collecting box 701, and the back of the collecting box 701 is in contact with the front side surface of the lower mold 4. An oblique groove 702 is provided on the front inner wall surface of the slitting groove, and the collecting box 701 can collect and process the debris that slides through the oblique groove 702. The inner front end of the slitting groove is fixedly connected with a fixed oblique block 703, and the right end of the fixed oblique block 703 is located in the same horizontal plane as the left inner wall surface of the oblique groove 702. A movable oblique block 704 is provided on the left side of the fixed oblique block 703, and the outer wall surfaces of the fixed oblique block 703 and the movable oblique block 704 are both in contact with the inner wall of the slitting groove. The ends of the upper surfaces of the movable bevel block 704 that are away from each other are arranged in an inclined structure. The debris that falls downward during trimming will slide along the inclined surfaces of the fixed bevel block 703 and the movable bevel block 704 into the cutting groove, and will not accumulate on the fixed bevel block 703 and the movable bevel block 704. The front end of the upper surface of the movable bevel block 704 is fixedly connected to a connecting plate 705. After the product is taken, the staff can drive the movable bevel block 704 to rotate one circle inside the cutting groove through the connecting plate 705, and push the debris inside the cutting groove to the oblique through groove 702, so that the debris slides along the inclined surface of the oblique through groove 702 into the collection box 701 for collection and processing, thereby avoiding a large amount of accumulation inside the cutting groove that is difficult to clean, resulting in obstruction to the subsequent movement of the cutter 605, affecting the subsequent trimming of the product.

[0039] Working principle: When the upper mold 3 moves downward and cooperates with the lower mold 4 to press and form the product, the cutter 605 will move downward synchronously with the upper mold 3 to pierce the edge of the product, and the rotating bolt 609 drives the U-shaped frame 610 to move downward and fit the upper surface of the product. Then the motor 601 can be started to drive the cutter 605 to rotate and trim the edge of the product. During the trimming process, the pressure roller 608 can slightly pull the trimmed edge of the product in the opposite direction to avoid wrinkles along the trimming direction of the product. The U-shaped frame 610 can scrape and clean the trimmed edge of the product to improve the quality of the product. After the product is taken, the connecting plate 705 drives the movable bevel block 704 to rotate inside the cutting groove for one circle, and the debris is cleaned through the bevel groove 702 to avoid affecting the subsequent movement of the cutter 605.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
