Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a sliding cold and hot pressing edge wrapping mold. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the required products through methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. A large number of molds are needed in the automobile manufacturing process to produce various parts, and cold pressing and hot pressing hemming technologies are widely used on the production line.

[0022] Reference Figure 1-3 The utility model provides a technical solution: a sliding hot and cold pressing hemming mold, comprising an upper template 2 and a lower template 6, the bottom of the upper template 2 is provided with an upper mold 3, the upper template 2 is provided with an upper hot mold 15 and an upper cold mold 17, the top of the lower template 6 is provided with a lower supporting membrane 10, and a linear guide rail 13 is fixedly installed above the lower template 6, and the top of the lower template 6 is provided with a lower mold 4, and the lower mold 4 is slidably installed on the linear guide rail 13. By setting the linear guide rail 13, the operator places the product on the lower supporting membrane 10 and moves the lower mold 4 on the linear guide rail 13 until the lower mold 4 moves to the bottom of the upper hot mold 15. At this time, the equipment is started to hot-press the product. After completion, the lower mold 4 is continued to be moved to make it reach the bottom of the upper cold mold 17 to continue cold-pressing the product, so that the continuous operation of hot pressing and cold pressing of the product does not need to be realized by a flipping structure, which simplifies the structure and saves costs.

[0023] Reference Figure 1-3 The lower mold 4 is provided with a hot air system 8 and a heater 9. The hot air system 8 is located inside the lower mold 4. By providing the hot air system 8 and the heater 9, the heater 9 can be a resistance heater 9 or an electromagnetic heater 9, etc., and its main effect is to provide a heat source. The hot air system 8 includes an air processing part and a control part. The air processing part can transfer the heat generated by the heat source to the air to heat the air, such as a heat exchanger. The control part can detect and control the temperature of the hot air system 8, such as a temperature controller, thereby improving the effect of hot pressing;

[0024] Reference Figure 1-3 The lower mold 4 is provided with a hanging pin system 11 and a latch system 7. The hanging pin system 11 is located at the top of the lower mold 4. The hanging pin system 11 is composed of a hanging pin body and a mounting seat. The hanging pin body is restricted by the guide groove built into the mounting seat so that the hanging pin body can only move along a preset track. The product is positioned on the lower mold 4 through the connection between the hanging pin and the mounting seat.

[0025] Reference Figure 1-3A driving cylinder 12 is installed on the top of the lower mold plate 6. The output end of the driving cylinder 12 is connected to the lower mold 4. By setting the driving cylinder 12, the operator can start the driving cylinder 12 to make the lower mold 4 slide on the linear guide rail 13, thereby providing driving force for the movement of the lower mold 4.

[0026] Reference Figure 1-3 A positioning frame is provided between the upper template 2 and the lower template 6, an upper mold positioning column 1 is provided between the upper template 2 and the positioning frame, and a lower mold positioning block 5 is provided between the lower template 6 and the positioning frame. By providing the upper mold positioning column 1 and the lower mold positioning block 5, the operator installs the upper mold 3 on the upper template 2 through the upper mold positioning column 1, and installs the lower mold 4 on the lower template 6 through the lower mold positioning block 5, thereby greatly enhancing the versatility of the equipment;

[0027] Reference Figure 1-3 The upper mold 3 is provided with an inner hemming system 14 and an outer hemming system 16. The outer hemming system 16 is located on the side of the upper hot mold 15. By providing the inner hemming system 14 and the outer hemming system 16, during hot pressing, the inner hemming system 14 hems the concave area of the product, and the outer hemming system 16 hems the regular part of the product, thereby improving the hot pressing effect.

[0028] Reference Figure 1-3 An adjustment base 18 is installed on the upper template 2, and the upper cold mold 17 is installed on the adjustment base 18. By setting the adjustment base 18, the position and angle of the upper cold mold 17 can be adjusted according to actual needs, so that the contact between the product and the cold mold is closer.

[0029] Specifically, the working process or working principle of the sliding hot and cold pressing hemming mold is as follows: when in use, the operator places the mold on the equipment with a mold changing trolley, fixes the upper mold plate 2 on the upper part of the positioning frame through the upper mold positioning column 1, fixes the lower mold plate 5 on the lower part of the positioning frame through the lower mold positioning block 6, and places the product skeleton on the lower supporting membrane 10, and positions the product skin through the hanging needle mechanism 11 so that the skin is accurately positioned on the skeleton. After the placement is completed, the operator presses the start button on the equipment to drive the cylinder 12 to move in a straight line. Under the guidance of the guide rail 13, the lower supporting membrane 10 is driven to the hot pressing position, the upper mold 3 descends, and the upper hot mold 15 hot presses the product. At the same time, the hot air mechanism 8 blows hot air to the concave area of the product, the inner edge wrapping mechanism 14 wraps this area, and the outer edge wrapping mechanism 16 wraps the conventional area. After the hot pressing is completed, the upper mold 3 rises, and the driving cylinder 12 drives the lower supporting membrane 10 to the cold pressing position, the upper mold 3 descends, and the upper cold mold 17 cold presses the product to ensure the tearing force of the concave area of the product. After the cold pressing is completed, the upper mold 3 rises and the operator takes the product.
