Description

Technical Field

[0001] This utility model belongs to the field of automated mold technology, and in particular relates to an automatic rotary structure forming mold. Background Technology

[0002] In the manufacturing of home appliances, components such as the outer shell are usually manufactured using stamping dies. Many home appliance parts have complex structures and require edge folding to achieve protection and aesthetics. In existing processing dies, the sides of the workpiece are bent multiple times to form a wrapping structure. When the workpiece is unloaded after forming, the wrapping structure makes unloading difficult, and the workpiece is also prone to wear or deformation. At the same time, the unloading process is time-consuming and reduces production efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic rotating structure forming mold that can quickly unload the formed workpiece and improve production efficiency.

[0004] To achieve the above objectives, this utility model employs the following technical solution: an automatic rotating structure forming mold, comprising an upper mold and a lower mold, wherein the lower mold has a support platform at its top for placing a workpiece, the upper mold has a pressure plate at its bottom for pressing the workpiece, and both sides of the support platform have fixed seats, with arc-shaped tracks on both sides of the fixed seats. A rotating mechanism for bending the workpiece is slidably connected to the arc-shaped tracks, and a push rod mechanism is provided on one side of the rotating mechanism. The output end of the push rod mechanism is hinged to the rotating mechanism for driving the rotating mechanism to slide along the arc-shaped tracks.

[0005] Optionally, the rotating mechanism includes at least two side plates, which are slidably connected to the arc-shaped track, and a forming block is disposed between the two side plates, which is slidably connected to the inner side of the fixed seat.

[0006] Optionally, a connecting rod is installed on one side of the side plate, and an annular groove is formed on the outer wall of the connecting rod. A sleeve rod is rotatably connected to the annular groove, and one end of the sleeve rod is fixedly connected to the output end of the push rod mechanism.

[0007] Optionally, a support block is fixedly connected to one side of the molding block, the outer wall of the support block is in contact with the inner wall of the side plate, and a top block is provided at one end of the support block.

[0008] Optionally, a nitrogen spring is provided at the bottom of the upper mold. When the upper mold and the lower mold are closed, the end of the nitrogen spring abuts against the end of the support block for auxiliary positioning.

[0009] Optionally, a blocking block is provided on one side of the support platform, and a blocking plate is provided at the end of the fixed seat away from the support platform. The blocking block and the blocking plate are used to limit the rotation mechanism.

[0010] Optionally, the top of the support platform and the bottom of the pressure plate are both arc-shaped.

[0011] Optionally, the push rod mechanism is a pneumatic cylinder, and an air pipe interface is provided on one side of the push rod mechanism.

[0012] Optionally, at least two sensing mechanisms are provided on one side of the fixed base, and a sensing plate that cooperates with the sensing mechanisms is provided on one side of the side plate.

[0013] Optionally, the bottom of the upper mold is provided with at least two guide rods, and the top of the lower mold is provided with a guide sleeve corresponding to the guide rods.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: 1. By setting a rotating mechanism on the top of the lower mold and a push rod mechanism on one side of the rotating mechanism, when the upper mold and the lower mold are pressed together, the end of the push rod mechanism extends to drive the side plate and the forming block to rotate, so as to complete the forming process of the workpiece. Then the end of the push rod mechanism retracts, driving the side plate and the forming block to rotate in the opposite direction, quickly completing the unloading process, which greatly improves the processing efficiency.

[0015] 2. By setting a fixed seat at the top of the lower mold, and opening an arc-shaped track on the fixed seat, the side plate and the forming block are slidably connected to the arc-shaped track. The end of the forming block rotates and extrudes the workpiece to realize the workpiece forming process. The forming block slides along the arc-shaped track to avoid interference with the workpiece's wrapping structure and improve the unloading efficiency. Attached Figure Description

[0022] The pressure plate 4 and the upper mold 1 are connected by an elastic element to achieve a buffering effect. The length of the pressure plate 4 is greater than the length of the support platform 3. There are two fixing seats 5, located on both sides of the support platform 3 respectively, and they are fitted into the support platform 3.

[0023] Example 2 This embodiment provides an automatic rotating structure forming mold, which differs from the first embodiment in that the rotating mechanism 6 includes at least two side plates 601, the side plates 601 are slidably connected to the arc track 501, a forming block 602 is provided between the two side plates 601, and the forming block 602 is slidably connected to the inner side of the fixed seat 5.

[0024] A connecting rod 603 is installed on one side of the side plate 601. An annular groove is provided on the outer wall of the connecting rod 603. A sleeve rod 604 is rotatably connected to the annular groove. One end of the sleeve rod 604 is fixedly connected to the output end of the push rod mechanism 7.

[0025] A support block 605 is fixedly connected to one side of the molding block 602. The outer wall of the support block 605 is in contact with the inner wall of the side plate 601. A top block 606 is provided at one end of the support block 605.

[0026] A nitrogen spring 8 is provided at the bottom of the upper mold 1. When the upper mold 1 and the lower mold 2 are closed, the end of the nitrogen spring 8 presses against the end of the support block 605 for auxiliary positioning.

The outer wall of the forming block 602 is always in contact with the inner wall of the fixed base 5. The push rod mechanism 7 is located inside the lower mold 2, and the support block 605 is located outside the lower mold 2. When the upper mold 1 and the lower mold 2 are fully pressed together, the end of the nitrogen spring 8 contacts the top block 606.

[0028] A blocking block 9 is provided on one side of the support platform 3, and a blocking plate 10 is provided at the end of the fixed base 5 away from the support platform 3.

[0031] In use, the push rod mechanism 7 is connected to the solenoid valve and other electrical mechanisms. Activating the push rod mechanism 7 returns the rotating block to its initial state. Figure 4 As shown; the workpiece is placed in the corresponding position on the support platform 3, and the upper mold 1 is driven to move downwards until the workpiece is pressed. At the same time, the output end of the push rod mechanism 7 extends outwards, driving the forming block 602 to rotate along the arc track 501 to the maximum stroke state, as shown. Figure 5 As shown; thus realizing the workpiece forming process, after the workpiece is fully formed, the output end of the push rod mechanism 7 retracts inward, driving the forming block 602 to return to the initial state, that is, completing the unloading process.
