Technical Field
[0001] This utility model relates to the field of press mold technology, and in particular to a press mold lifting mechanism. Background Technology
[0002] The traditional workshop's original 650-ton press clamping fixture has a circular worktable with a diameter of φ750mm. Due to size limitations, the upper and lower circular table surfaces cannot meet the production needs of some existing workpieces.
[0003] The existing press equipment can be upgraded and modified within its limited space. The tooling equipment can be redesigned to meet the needs of production and processing. By replacing the upper and lower circular table surfaces with upper and lower long strip flat pressure plates, the production of long and thin strip blade workpieces can be met.
[0004] However, during production and processing, the workpieces for extended thin strip blades are usually large in size, making it difficult for operators to load and unload the workpieces on the processing table. Utility Model Content
[0005] The purpose of this utility model is to provide a press mold lifting mechanism, which aims to solve the problem that during production and processing, the workpieces of the extended thin strip blade are usually large in size, making it difficult for operators to load and unload the workpieces on the processing table.
[0006] To achieve the above objectives, this utility model provides a press mold lifting mechanism, including a frame, a fixed frame, a processing table, and a pressing assembly. The fixed frame is fixedly connected to the frame and located on one side of the frame. The processing table is fixedly connected to the fixed frame. The pressing assembly is disposed on the frame and located on one side of the frame.
[0007] It also includes the pop-out component.
[0008] The ejection assembly includes a movable frame, a ramp protrusion, a movable block, a sliding wheel, a flow strip, and a movable component. The movable frame is slidably connected to the fixed frame and located on one side of the fixed frame. The ramp protrusion is fixedly connected to the movable frame and located on one side of the movable frame. The movable block is connected to the processing table and located on one side of the processing table. The sliding wheel is rotatably connected to the movable block and located on the side of the movable block near the ramp protrusion. The flow strip is fixedly connected to the movable block and located on one side of the movable block. The movable component is disposed on the processing table.
[0009] The movable component includes a connecting bracket, a push plate, and a driving component. The connecting bracket is connected to the processing table via the driving component and is located on one side of the processing table. The push plate is fixedly connected to the connecting bracket and is located on one side of the connecting bracket. The driving component is disposed on the processing table and connected to the connecting bracket.
[0010] The driving component includes a mounting bracket and a cylinder. The mounting bracket is fixedly connected to the processing table and is located on one side of the processing table.

The lifting frame is fixedly connected to the lifting column and the pressing table, and is located on the side of the lifting column closer to the pressing table.
[0013] This utility model discloses a press mold lifting mechanism. When the product is pressed and the mold needs to be ejected, the moving component is manually activated to move the moving frame to the right. This rightward movement of the moving frame allows the sliding wheel to roll on it. During this movement, the sliding wheel rolls along the inclined surface of the ramp protrusion to its apex. As the sliding wheel climbs along the inclined surface, it drives the moving block upwards. This upward movement of the moving block then drives the flow strip upwards. The movement of the flow strip, under the force of the cylinder, pushes the mold 1-5mm above the worktable. At this point, the operator can manually push the mold to the left onto the lifting platform for demolding. After the mold is loaded onto the lifting platform, the flow strip pushes it above the processing table. The operator then manually activates the moving component to move the moving frame to the left, causing the flow strip to descend and the mold to fully contact the worktable, thus starting the pressing program and pressing the product. The lifting and moving of the flow strip facilitates the operator's loading and unloading of the pressed workpiece onto the processing table. Attached Figure Description

[0023] This utility model provides a press mold lifting mechanism, including a frame 101, a fixed frame 102, a processing table 103, a pressing assembly, and an ejection assembly. The ejection assembly includes a movable frame 104, a ramp protrusion 105, a movable block 106, a sliding wheel 107, a flow strip 108, and a moving component. The moving component includes a connecting bracket 109, a push plate 110, and a driving component. The driving component includes a mounting frame 111 and a cylinder 112. The pressing assembly includes a pressing table 113 and a lifting component. The lifting component includes a lifting column 114 and a lifting frame 115. This solution addresses the challenge of loading and unloading long, thin strip-shaped workpieces on the processing table during production, where their large size makes loading and unloading difficult. This solution can be used in situations where easy loading and unloading of workpieces on the processing table is required.
[0024] In this embodiment, there are two fixing frames 102, which are bolted to the frame 101. The processing table 103 is bolted to the two fixing frames 102. The fixing frames 102 can connect and support the processing table 103. The pressing assembly is disposed on the frame 101. The pressing assembly, in conjunction with the processing table 103, can press the workpiece placed on the processing table 103.
[0025] The movable frame 104 is slidably connected to the fixed frame 102 and located on one side of the fixed frame 102. The ramp protrusion 105 is fixedly connected to the movable frame 104 and located on one side of the movable frame 104. The movable block 106 is connected to the processing table 103 and located on one side of the processing table 103. The sliding wheel 107 is rotatably connected to the movable block 106 and located on the side of the movable block 106 near the ramp protrusion 105. The flow strip 108 is fixedly connected to the movable block 106 and located on one side of the movable block 106. The movable component is disposed on the processing table 103. There are two movable frames 104, and the two movable frames 104 are slidably connected to the fixed frame 102. On the two corresponding fixed frames 102, there are multiple ramp protrusions 105. These ramp protrusions 105 are integrally connected and fixed to the two corresponding movable frames 104. There are two movable frames 104, connected to both sides of the processing table 103, and capable of moving up and down within a certain range on both sides of the processing table 103. There are multiple sliding wheels 107, rotatably connected to the two corresponding movable blocks 106. The sliding wheels 107 can roll on the movable frames 104. Therefore, when the movable frames 104 move left and right, it drives the ramp protrusions 105 to move. The left and right movement of the movable frames 104 causes the ramp protrusions 105 to move. 7. The sliding wheel 107 can roll on the movable frame 104. During the movement of the movable frame 104, the sliding wheel 107 rolls along the inclined surface of the ramp protrusion 105 to the apex of the ramp protrusion 105. This causes the sliding wheel 107 to climb along the inclined surface of the ramp protrusion 105, driving the movable block 106 upwards. There are two flow bars 108, welded to corresponding movable blocks 106. The upward movement of the movable blocks 106 drives the upward movement of the flow bars 108. The flow bars 108 consist of a track and rollers. The moving component is mounted on the processing table 103. The moving component enables the moving block 106 to move upwards. The left and right movement of the frame 104 provides the corresponding power source, thus enabling manual operation to activate the moving component to move the moving frame 104 to the right when the product pressing is completed and the mold needs to be ejected. This rightward movement of the moving frame 104 allows the sliding wheel 107 to roll on it. During this movement, the sliding wheel 107 rolls along the inclined surface of the ramp protrusion 105 to its apex. As the sliding wheel 107 climbs along the inclined surface of the ramp protrusion 105, it drives the moving block 106 upward. This upward movement of the moving block 106 then drives the flow strip 108 upward.The flow bar 108, under the force of cylinder 112, pushes the mold 1-5mm above the worktable. At this point, the operator can manually push the mold to the left onto the lifting platform for demolding. After the mold is loaded onto the lifting platform, the flow bar 108 pushes it above the processing table 103. The operator then manually activates the moving component, which moves the moving frame 104 to the left, causing the flow bar 108 to descend and the mold to fully contact the worktable. This initiates the pressing process, pressing the product. The lifting and lowering movement of the flow bar 108 facilitates the operator's loading and unloading of the pressed workpiece onto the processing table 103.
[0026] Secondly, the connecting bracket 109 is connected to the processing table 103 via the driving component and is located on one side of the processing table 103; the push plate 110 is fixedly connected to the connecting bracket 109 and is located on one side of the connecting bracket 109; the driving component is disposed on the processing table 103 and connected to the connecting bracket 109, the connecting bracket 109 is connected to the right side of the processing table 103 via the driving component, and the driving output of the driving component can drive the connecting bracket 109 to move left and right; the push plate 110 is bolted and fixedly installed on the connecting bracket 109, and the left and right movement of the connecting bracket 109 can drive the push plate 110 to move left and right; the push plate 110 is bolted and fixedly installed on the moving frame 104, and the left and right movement of the push plate 110 can drive the moving frame 104 to move left and right.
[0027] Meanwhile, the mounting bracket 111 is fixedly connected to the processing table 103 and is located on one side of the processing table 103; the cylinder 112 is fixedly connected to the mounting bracket 111 and connected to the connecting bracket 109, and is located on the side of the mounting bracket 111 close to the connecting bracket 109. The mounting bracket 111 is bolted to the processing table 103, the cylinder 112 is bolted to the mounting bracket 111, and the connecting bracket 109 is connected to the output end of the cylinder 112, so that the connecting bracket 109 can be moved left and right by the driving output of the cylinder 112.
[0028] In addition, the pressing table 113 is connected to the frame 101 through the lifting member and is located on the side of the frame 101 near the processing table 103. The lifting member is disposed on the frame 101 and connected to the pressing table 113. The pressing table 113 is connected to the frame 101 through the lifting member. The movement of the lifting member can drive the pressing table 113 to move up and down, thereby pressing the mold on the processing table 103 through the movement of the pressing table 113. The lifting member is disposed on the frame 101 and connected to the pressing table 113. The lifting member can be connected to an external lifting drive source and can also provide connection support and directional limit for the lifting of the pressing table 113.
[0029] Finally, the lifting column 114 is slidably connected to the frame 101 and located on one side of the frame 101; the lifting frame 115 is fixedly connected to the lifting column 114 and the pressing table 113 respectively. The lifting frame 115 is located on the side of the lifting column 114 near the pressing table 113. There are four lifting columns 114, which are slidably connected to the frame 101. The lifting frame 115 is welded to the four lifting columns 114. The movement of the lifting column 114 can connect, support, and directional limit the movement of the lifting frame 115. An external drive source can drive the lifting frame 115 to move downwards. The pressing table 113 can press the mold on the processing table 103.
[0030] When using the press mold lifting mechanism of this embodiment, when the product is pressed and the mold needs to be ejected, the moving component is manually activated to move the moving frame 104 to the right. The rightward movement of the moving frame 104 causes the sliding wheel 107 to roll on the moving frame 104. During the movement of the moving frame 104, the sliding wheel 107 rolls along the inclined surface of the ramp protrusion 105 to the apex of the ramp protrusion 105. As the sliding wheel 107 climbs along the inclined surface of the ramp protrusion 105, it drives the moving block 106 upward. The upward movement of the moving block 106 then drives the flow... The upward movement of the flow bar 108 causes the flow bar 108 to push the mold out of the worktable by 1-5mm under the force of the cylinder 112. At this time, the operator can push the mold to the left by hand onto the lifting platform for demolding. After the mold is loaded on the lifting platform, the flow bar 108 pushes the mold to the top of the processing table 103. The operator manually starts the moving component to move the moving frame 104 to the left, causing the flow bar 108 to descend and the mold to fully contact the worktable, starting the pressing program and pressing the product. The lifting and moving of the flow bar 108 facilitates the operator to load and unload the pressed workpiece on the processing table 103.
