Description

Technical Field

[0001] This utility model relates to the field of forming molds, and in particular to a multifunctional universal forming mold with adjustable radius of curvature. Background Technology

[0002] Compression molding die is a key tool in material forming and processing. It is used to press metal or non-metal materials into specific shapes and is widely used in the manufacturing fields of automobiles, home appliances and so on. Its role is to provide a precise shape basis for material forming, ensure product specification uniformity, and improve production efficiency and quality. For example, automotive body panels, home appliance shells and other parts all rely on compression molding die to complete the forming.

[0003] The tool consists of a die, a positioning device, and a fixing device. The die determines the final shape of the material and needs to be processed according to the product design. The positioning device is used to accurately determine the position of the material, and the fixing device prevents the material from shifting during pressing. In terms of material selection, steel and cast iron are more common. The former has high strength and good toughness and is suitable for high-pressure molding, while the latter is wear-resistant and low-cost, and is suitable for mass production. According to the molding process, the forming die can be divided into stamping, extrusion, and rolling die types to adapt to different production needs.

[0004] When using a forming die, the die is replaced with the appropriate mold according to different product requirements. Then, a hydraulic cylinder or other driving device is used to press the workpiece material between the molds to produce the specified product. However, in traditional forming dies, the mold is fixed to the die with bolts and nuts. When changing the mold, auxiliary tools must be used, and it cannot be changed quickly. To solve this problem, a multi-functional universal forming die with adjustable curvature radius is proposed. Utility Model Content

[0036] Working Principle: When using this device to press workpieces, first change the corresponding lower mold 2 and upper mold 3 according to the model of the workpiece to be produced. By moving the lever 7, the slide plate 6 is driven to compress the spring 5, causing the insertion rod 8 to retract into the outer shell 4 and disengage from the lower mold 2 or upper mold 3. At the same time, the stop block 9 will automatically fall down to block the outlet of the insertion rod 8. At this time, the lower mold 2 or upper mold 3 is unlocked. Then, the lower mold 2 and upper mold 3 are removed from the fixture body 1 and the lower mold 2 and upper mold 3 corresponding to the product are placed on top. Finally, the lever 10 is pulled upwards, causing the stop block 9 to disengage from the insertion rod 8. At this time, the spring 5 will instantly push the slide plate 6 to reset, causing the insertion rod 8 to pop out and insert into the lower mold 2 or upper mold 3, fixing the lower mold 2 and upper mold 3. The die is fixed on the main body 1, allowing for quick replacement of the lower mold 2 and upper mold 3. The workpiece material is then placed into the lower mold 2, and the motor 11 is controlled to rotate, driving the worm gear 12 to rotate. Engaging with the worm wheel 14, the rotating rod 13 rotates. Simultaneously, with the limiting rod 17, the turntable 15 begins to move the two clamps 16 towards the center point, clamping the workpiece and preventing displacement. The main body 1 is then controlled to adjust the radius of curvature, pressing the upper mold 3 onto the workpiece in the lower mold 2, shaping the workpiece and lifting the upper mold 3. Finally, the motor 11 is reversed, moving the two clamps 16 away from the workpiece, thus completing the pressing production of one workpiece. The operation is convenient and labor-saving, effectively improving production efficiency.
