Description

Technical Field

[0001] This invention relates to the field of hot pressing molding technology, and in particular to a fully automatic double-ball hot pressing molding device. Background Technology

[0002] Double-sphere thermoforming is an advanced manufacturing method combining thermoforming technology with a two-sheet process. It achieves integrated molding of a hollow structure by simultaneously shaping two thermoplastic sheets under high temperature and pressure. This process overcomes the limitations of traditional single-sheet thermoforming, utilizing the simultaneous heating and softening of two layers of sheets in a mold. Vacuum adsorption or mechanical pressure is then used to press the material tightly into the mold cavity, ultimately forming a hollow product with double-sided characteristics. Its core advantage lies in its ability to manufacture parts with complex structures, uniform wall thickness, and internal cavities, such as lightweight spheres in sports equipment, sound and heat insulation components in the automotive industry, and streamlined shells in the aerospace field.

[0003] The significance of this process lies in its multi-dimensional innovative breakthroughs. In terms of material utilization, the double-sheet design significantly reduces raw material consumption through its internal cavity structure, which can reduce material costs by more than 30% compared to traditional solid molding. At the same time, the hollow structure gives the product superior lightweight characteristics. Secondly, the process has extremely strong compatibility, which can handle a variety of sheet thicknesses from 0.5mm to 15mm and supports more than ten kinds of thermoplastic plastics such as PS, PC, and PETG, meeting the different needs of various industries for strength, corrosion resistance, and transparency.

[0004] Existing molding technologies are inefficient. They require placing the raw materials before hot pressing, removing the finished product, placing new materials, and then hot pressing again. The process is cumbersome and slow. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention discloses a fully automatic double-ball hot pressing molding device, which effectively solves the problems in the background art. In use, this invention features two adjacent sets of hot pressing modules, enabling rapid alternating hot pressing molding. While one set is hot pressing, the other set performs real-time feeding and unloading. After hot pressing molding is completed, the other set can seamlessly connect, greatly improving hot pressing efficiency. This invention also includes automatic control of the movement of the intermediate mold, achieving fully automatic feeding or unloading without manual intervention.

[0006] A fully automatic double-ball hot pressing molding device includes a bed and a support plate. Two support plates are fixedly installed in the middle of the bed, and a pad is fixedly installed on the upper side of the support plate. The lower molds on both sides of the pad are fastened to the pad by bolts. An intermediate plate is fixedly installed between the two lower molds. A hinge seat is provided on the intermediate plate, and an upper mold is rotatably installed on the hinge seat. The upper mold has sliding grooves on both sides, and a lever is slidably installed in the sliding groove. The lever is fixedly connected to a rotating shaft. The shaft is rotatably installed in a circular hole on the side of the bed. A worm gear is fixedly installed in the middle of the rotating shaft. The worm gear meshes with a worm. The two ends of the worm are rotatably installed in circular holes in an extension plate below the support plate. One end of the worm is also connected to the motor shaft of a stepper motor I. The stepper motor I is fixedly installed on the extension plate below the support plate.

[0007] Preferably, the lower mold has an elliptical slot, in which a corresponding intermediate mold can be placed. One end of the intermediate mold has two connected rectangular protrusions. The outer protrusion extends beyond the lower mold, while the inner protrusion is engaged in a rectangular slot on the lower mold. The elliptical part in the middle of the intermediate mold is thinner than the protrusions. Therefore, the upper and lower surfaces of the intermediate mold do not contact the slot on the lower or upper mold, leaving a certain space.

[0008] A support column is fixedly installed on the beam in the middle of the preferred bed. The support column has sliding grooves on both sides, and side rods are slidably installed in the sliding grooves. The side rods are threadedly connected to a vertical lead screw. The two ends of the vertical lead screw are rotatably installed in the round holes on the upper and lower sides of the support column. The lower end of the vertical lead screw is connected to the motor shaft of stepper motor II. Stepper motor II is fixedly installed on the lower extension plate of the support column.

[0009] The preferred side rod has an extension plate on its side, on which a horizontal lead screw I is rotatably mounted. One end of the horizontal lead screw I is also connected to the motor shaft of a stepper motor III, which is fixedly mounted on the extension plate on the side of the side rod. The horizontal lead screw I is also threadedly connected to a sliding frame, which is slidably mounted on the side rod.

[0010] The preferred sliding frame has square slots on its upper and lower surfaces. A demolding rod is slidably installed in the slots and is threadedly connected to a horizontal lead screw II. Both ends of the horizontal lead screw II are rotatably installed in the round holes on the sliding frame. One end of the horizontal lead screw II is connected to the motor shaft of a stepper motor IV. The stepper motor IV is fixedly installed in the slot of the sliding frame. The sliding frame is fixedly connected to the square protrusion on the outer side of the intermediate mold by bolts.

[0011] The preferred demolding rod has a folded shovel on its left side, and the left side of the demolding rod is made of leaf spring material, with the upper and lower ends generating elastic force inward relative to each other.

[0012] The preferred bed is also fixedly installed with a base plate on both sides, and a storage trough is fixedly installed on the base plate. The shape of the storage trough is the same as the shape of the slot on the middle mold, and a film of a fixed shape can be placed in the storage trough.

[0013] A side plate is fixedly installed on the side of the preferred bed. A cylinder II is fixedly installed on the outer end of the side plate. The piston rod of cylinder II is fixedly connected to the telescopic frame. The slide rod on the telescopic frame is slidably installed in the round hole on the side plate. A cylinder I is also fixedly installed on the upper end of the telescopic frame. The piston rod of cylinder I is fixedly connected to the connecting plate. The connecting plate is fixedly installed on the slide rod on the picking plate. The slide rod on the picking plate is slidably installed in the round hole on the telescopic frame. The shape of the picking plate is the same as the shape of the storage tank. Multiple suction cups are also fixedly installed on the picking plate. The suction cups can pick up the film in the storage tank.

[0014] The beneficial effects of this invention compared with the prior art are: 1. When this invention is used, it is equipped with two adjacent sets of hot pressing modules, which can perform rapid alternating hot pressing molding. While one set is hot pressing, the other set is feeding and unloading in real time. After the hot pressing molding is completed, the hot pressing of the other set can be seamlessly connected, which greatly improves the hot pressing efficiency. 2. The present invention also features automatic control for the movement of the intermediate mold, achieving full automation during loading or unloading without manual intervention.

Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The outer protrusion extends beyond the lower mold 4, while the inner protrusion is engaged in a rectangular slot on the lower mold 4. The elliptical part in the middle of the intermediate mold 5 is thinner than the protrusions. Therefore, the upper and lower surfaces of the intermediate mold 5 do not contact the slot on the lower mold 4 or the upper mold 7, leaving a certain space.

[0031] In one alternative embodiment of the present invention, such as Figure 5 , Figure 6 As shown, a support column 13 is fixedly installed on the beam in the middle of the bed 1.

[0033] In one alternative embodiment of the present invention, such as Figure 6 , Figure 7As shown, the upper and lower surfaces of the sliding frame 19 are provided with square slots, and a demolding rod 20 is slidably installed in the slots. The demolding rod 20 is threadedly connected to the horizontal lead screw II 21. Both ends of the horizontal lead screw II 21 are rotatably installed in the round holes on the sliding frame 19. One end of the horizontal lead screw II 21 is connected to the motor shaft of the stepper motor IV 22. The stepper motor IV 22 is fixedly installed in the slot of the sliding frame 19. The sliding frame 19 is fixedly connected to the outer square protrusion of the intermediate mold 5 by bolts.

[0034] In one alternative embodiment of the present invention, such as Figure 8 , Figure 9 As shown, the left end of the demolding rod 20 is provided with a folded shovel, and the left end of the demolding rod 20 is made of leaf spring material, with the upper and lower ends generating elastic force inward relative to each other.

[0035] In one alternative embodiment of the present invention, such as Figure 10 As shown, a base plate 23 is fixedly installed on both sides of the bed 1. A storage trough 24 is fixedly installed on the base plate 23. The shape of the storage trough 24 is the same as the shape of the slot on the intermediate mold 5. A film of a fixed shape can be placed in the storage trough 24.

[0036] In one alternative embodiment of the present invention, such as Figure 11 As shown, a side plate 30 is fixedly installed on the side of the bed 1. A cylinder II 31 is fixedly installed on the outer end of the side plate 30. The piston rod of the cylinder II 31 is fixedly connected to the telescopic frame 28. The slide rod on the telescopic frame 28 is slidably installed in the round hole on the side plate 30. A cylinder I 29 is also fixedly installed on the upper end of the telescopic frame 28. The piston rod of the cylinder I 29 is fixedly connected to the connecting plate 27. The connecting plate 27 is fixedly installed on the slide rod on the picking plate 25. The slide rod on the picking plate 25 is slidably installed in the round hole on the telescopic frame 28. The shape of the picking plate 25 is the same as the shape of the storage tank 24. Multiple suction cups 26 are also fixedly installed on the picking plate 25. The suction cups 26 can pick up the film in the storage tank 24.

[0037] Working principle: In use, the device has two sets of lower molds 4 for hot pressing on both sides, which can perform alternating hot pressing. First, the material is loaded. The stepper motor II 16 at one end is started, which drives the vertical lead screw 15 to rotate, thereby driving the side rod 14 to slide upward, which in turn drives the sliding frame 19 to slide upward, so that the middle mold 5 also moves upward synchronously. Then, the cylinder I 29 drives the picking plate 25 to move downward, and the suction cup 26 grabs the film in the storage tank 24. Then, the cylinder II 31 pushes the suction cup 26 to the slot on the lower mold 4. At this point, the intermediate mold 5 is lifted, allowing the film to be smoothly placed into the slot of the lower mold 4. Then, the grabbing plate 25 is reset, and the intermediate mold 5 is also reset, clamping the film in the gap between the intermediate mold 5 and the lower mold 4. Then, the grabbing plate 25 grabs the film again and moves to the slot on the lower mold 4, placing the film on top of the intermediate mold 5. This puts the upper and lower films in place, with the intermediate mold 5 acting as a divider, so that one of the spheres in the final double-ball formation can be formed. Next, the stepper motor I12 starts and drives the worm gear 11 to rotate, which in turn drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the lever 9 to rotate, which in turn drives the upper mold 7 to rotate towards the lower mold 4 that has been placed. Finally, the upper mold 7 and the lower mold 4 press the film together. Then, the upper mold 7 and the lower mold 4 are heated for hot pressing. During this hot pressing process, the above-mentioned feeding operation is performed on the lower mold 4 on the other side. After hot pressing is completed, the upper mold 7 is opened and flipped onto the lower mold 4 on the other side for hot pressing. Then, the middle mold 5 on the formed side is raised under the drive, and the hot-pressed ball is placed on the middle mold 5. Then, the stepper motor IV 22 is started, driving the horizontal lead screw II 21 to rotate, thereby driving the demolding rod 20 to slide inward. The spatula at the inner end of the demolding rod 20 scoops up the colloid on the middle mold 5, and the bend on the demolding rod 20 jams the opening of the colloid, thereby peeling the colloid off the middle mold 5 and causing the ball colloid to fall off, completing the hot pressing process. Repeating the above steps can complete the continuous alternating hot pressing operation, greatly improving the degree of automation and production efficiency.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
