Description

Technical Field

[0001] This application relates to the technical field of powder forming hydraulic equipment, and in particular to a powder forming hydraulic press with a demolding function. Background Technology

[0002] A powder forming hydraulic press is an industrial device specifically used to press powdered raw materials such as metals, ceramics, magnetic materials, and hard alloys into blanks of specific shapes and densities. It uses a hydraulic system to provide high pressure, which drives the upper and lower punches to press the powder in a bidirectional or unidirectional manner within the mold. This causes the powder to undergo plastic deformation and mechanical interlocking between the particles under high pressure, forming a blank with a certain strength and density.

[0003] In traditional powder molding manufacturing processes, demolding is a crucial but tedious step. This process typically requires manual operation or additional mechanical equipment, increasing the overall time and complexity of the process. More importantly, due to a lack of precise control, manual demolding can easily cause scratches, cracks, or other damage to the workpiece surface, thus affecting product quality and yield.

[0004] While existing hydroforming equipment can provide stable pressure during the pressing process, it still relies on manual or semi-automatic operation during the demolding stage. This not only increases labor costs but may also lead to a decrease in yield. Utility Model Content

[0005] To overcome the limitations of existing hydraulic molding equipment, which, despite providing stable pressure during the pressing process, still rely on manual or semi-automatic operation during the demolding stage—which not only increases labor costs but may also lead to a decrease in yield—this application provides a powder molding hydraulic press with a demolding function.

[0006] The powder forming hydraulic press with demolding function provided in this application adopts the following technical solution: A powder forming hydraulic press with demolding function includes a frame, a forming mold, and a pusher. A rod is vertically fixed on the top surface of the frame, and a hydraulic rod is horizontally fixed on the top surface of the rod. A lower pressure plate is vertically slidably inserted into the rod, and the top surface of the lower pressure plate is fixedly connected to the output end of the hydraulic rod. The forming mold is horizontally fixed on the top surface of the frame, and a pusher is provided on one side of the forming mold. Multiple mold cavities are evenly and vertically opened on the top surface of the forming mold, and a groove is opened on the bottom surface of the forming mold. A sliding plate is vertically slidably arranged in the groove of the forming mold, and multiple pusher plate columns are vertically fixed on the top surface of the sliding plate, and the multiple pusher plate columns are inserted into the multiple mold cavities of the forming mold.

[0007] By adopting the above technical solution, the frame supports the entire equipment structure, ensuring its stability; the rod frame is fixed on the top surface of the frame, providing guiding support for the up-and-down movement of the hydraulic rod; the hydraulic rod controls the lifting and lowering of the lower pressure plate to apply pressure to the raw material in the forming mold to complete the pressing process; the lower pressure plate is fixedly connected to the output end of the hydraulic rod, and its lifting and lowering movement cooperates with the forming mold to perform pressing; the forming mold is used to accommodate the powder material to be pressed and to produce the required shape during the pressing process; the pusher is responsible for pushing the formed part out of the mold after pressing to avoid adhesion and damage; the mold cavity is the part on the forming mold used to place and press the powder material; the groove and slide plate design allows the formed part to be pushed by the pusher plate pillars after pressing, achieving convenient and quick demolding. First, the raw material powder is pressed by the pressure of the lower pressure plate and the forming mold to form the required shape; then, the slide plate slides up and down in the groove, and multiple pusher plate pillars are inserted into the mold cavity, pushing upwards to make the formed part smoothly eject from the mold, completing the entire pressing and demolding process.

[0008] Optionally, a bracket is horizontally fixed to the bottom of the groove of the forming mold, and a return spring is vertically fixed to the top surface of the bracket, with the top of the return spring fixed to the bottom surface of the slide plate.

[0009] By adopting the above technical solution, a bracket is horizontally fixed at the bottom of the groove of the molding die. Its main function is to provide a stable support point to ensure that the slide can move smoothly on the bracket. A return spring is vertically fixed on the top surface of the bracket. Its function is to provide elastic restoring force to the slide, so that the slide can automatically return to its original position after the packaging or molding operation. The slide is located at the top of the return spring, and a return spring is fixed on its bottom surface to push the slide back to its original position along the bracket after the molding process is completed. When the molding die is working, the slide moves under specific operations to complete the molding or packaging task; after the task is completed, the slide automatically returns to its initial position under the restoring force of the return spring, thereby realizing the automation and efficiency of the operation.

[0010] Optionally, the pusher component includes a slide and a pusher plate. The slide is horizontally fixed on the outer wall of the forming mold, and a pusher plate is horizontally arranged above the slide. A slider is horizontally fixed on the bottom surface of the pusher plate, and the slider of the pusher plate is horizontally slidably assembled on the slide.

[0011] By adopting the above technical solution, the carriage is horizontally fixed on the outer wall of the forming mold, providing a horizontal guide rail for the pusher plate. The pusher plate slides horizontally on the carriage via a slider fixed on its bottom surface, and is used to push out the formed workpiece during the shaping process.

[0012] Optionally, a pusher motor is horizontally fixed at the end of the carriage away from the forming mold, and a pusher screw is horizontally fixed at the output end of the pusher motor.

[0013] By adopting the above technical solution, the pusher motor generates driving force by driving the pusher screw. The pusher screw is threadedly assembled with the screw hole plate, thereby converting the rotational motion of the motor into the linear motion of the pusher shovel through the threaded transmission.

[0014] Optionally, a screw hole plate is horizontally fixed at the end of the pusher plate away from the forming mold, and the screw hole plate is threaded through and assembled with the pusher screw.

[0015] By adopting the above technical solution, after the pusher motor is started, the pusher motor drives the pusher screw to rotate. The pusher screw pushes the pusher shovel plate to slide along the slide through the threaded engagement with the screw hole plate, thereby pushing the workpiece out of the forming mold.

[0016] Optionally, a nail plate is horizontally installed below the frame, and the nail plate is assembled by fixing nails.

[0017] By adopting the above technical solution, the frame, as the overall supporting structure, provides a stable foundation. The nail plate is fixed to the bottom of the frame with fixing nails, increasing overall stability and providing installation positions for subsequent components.

[0018] Optionally, a support spring is vertically fixed to the top surface of the nail plate, and the top of the support spring is fixed to the bottom surface of the frame.

[0019] By adopting the above technical solution, the support spring is vertically fixed on the top surface of the nail plate, and its top end is connected to the bottom surface of the frame. It can provide elastic restoring force when pushed by a slight external force, which helps to reduce shock and restore the original position.

[0020] Optionally, a vibration motor is horizontally fixed on the side end face of the frame.

[0021] By adopting the above technical solution, the vibration motor is installed on the side end face of the frame and can generate vibration to excite the low-frequency vibration of the platform, thereby realizing the uniform distribution of materials or the cleaning function of materials. The frame provides stable support, and the nail plate and support spring form an elastic support system, which effectively absorbs vibration and provides buffering, while the vibration motor promotes material distribution or cleaning through external vibration.

[0022] In summary, this application includes at least one of the following beneficial technical effects: During use, a vibration motor generates vibration, causing powder to fall into the mold cavity of the molding die; the support spring, together with the frame and nail plate, provides elastic support during vibration; the lower pressure plate, pushed by the hydraulic rod, compacts the powder to ensure molding quality; the pusher plate moves downward with the extrusion of the lower pressure plate during molding, and simultaneously, after the powder is molded, the restoring force of the return spring pushes the molded powder out of the mold cavity, eliminating the need for manual removal of the molded parts and improving molding material handling efficiency; the molding die is used to accommodate and shape the powder; the return spring plays a resetting role on the pusher plate; the hydraulic rod is responsible for pushing the lower pressure plate up and down; the bracket provides support for the pusher plate; the pusher component, through the cooperation of the pusher motor and the pusher screw, achieves the orderly ejection of the molded powder. First, powder is added to the top surface of the molding die, and the vibration motor causes the powder to fall into the mold cavity. Then, the hydraulic rod drives the lower pressure plate to press the powder in the mold cavity. The pusher plate slides down during the molding process and pushes the powder up under the elastic force of the return spring after the powder is formed. Finally, the pusher motor rotates the pusher screw, which drives the pusher plate to move laterally through the thread, pushing the molded powder out from the top surface of the mold, completing the unloading process.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a powder forming hydraulic press with a demolding function. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A powder forming hydraulic press with demolding function includes a frame 1, a forming mold 5, and a pusher 6. A rod 2 is vertically fixed on the top surface of the frame 1, and a hydraulic rod 4 is horizontally fixed on the top surface of the rod 2. A lower pressure plate 3 is vertically slidably inserted into the rod 2, and the top surface of the lower pressure plate 3 is fixedly connected to the output end of the hydraulic rod 4. The forming mold 5 is horizontally fixed on the top surface of the frame 1, and a pusher 6 is provided on one side of the forming mold 5.

A sliding plate 54 is vertically slidably arranged in the groove of the forming mold 5, and multiple pusher plate columns 55 are vertically fixed on the top surface of the sliding plate 54, and the multiple pusher plate columns 55 are inserted one by one into the multiple mold cavities 51 of the forming mold 5.

[0027] By adopting the above technical solution, the frame 1 is used to support the structure of the entire equipment and ensure its stability; the rod 2 is fixed on the top surface of the frame 1 to provide guiding support for the up and down movement of the hydraulic rod 4; the hydraulic rod 4 applies pressure to the raw material in the forming mold 5 by controlling the lifting and lowering of the lower pressure plate 3 to complete the pressing process; the lower pressure plate 3 is fixedly connected to the output end of the hydraulic rod 4 and presses the material in conjunction with the forming mold 5 through lifting and lowering movement; the forming mold 5 is used to accommodate the powder material to be pressed and to produce the required shape during the pressing process; the pusher 6 is responsible for pushing the formed part out of the mold after pressing to avoid sticking and damage; the mold cavity 51 is the part on the forming mold 5 used to place and press the powder material; the groove and slide plate 54 are designed so that after pressing, the formed part can be pushed by the pusher plate column 55 to achieve convenient and quick demolding. First, the raw material powder is pressed under the pressure of the lower pressure plate 3 and the forming mold 5 to form the required shape; then, the slide plate 54 slides up and down in the groove, and multiple pusher plate pillars 55 are inserted into the mold cavity 51. By pushing upward, the molded part is smoothly removed from the mold, completing the entire pressing and demolding process.

[0028] Reference Figure 4A bracket 52 is horizontally fixed to the bottom of the groove of the molding mold 5, and a return spring 53 is vertically fixed to the top surface of the bracket 52. The top of the return spring 53 is fixed to the bottom surface of the slide plate 54. The bracket 52, which is horizontally fixed to the bottom of the groove of the molding mold 5, mainly provides a stable support point to ensure that the slide plate 54 can move smoothly on the bracket 52. The return spring 53, which is vertically fixed to the top surface of the bracket 52, provides elastic restoring force to the slide plate 54, so that the slide plate 54 can automatically return to its original position after the packaging or molding operation. The slide plate is located at the top of the return spring 53, and the return spring 53 is fixed to its bottom surface. It is used to push the slide plate 54 back to its original position along the bracket 52 after the molding process is completed. When the molding mold 5 is working, the slide plate 54 will move under specific operations to complete the molding or packaging task; after the task is completed, the slide plate 54 will automatically return to the initial position under the restoring force of the return spring 53, thereby realizing the automation and efficiency of the operation.

[0029] Reference Figure 5 The pusher component 6 includes a slide 61 and a pusher plate 64. The slide 61 is horizontally fixed to the outer wall of the forming mold 5, and the pusher plate 64 is horizontally arranged above the slide 61. A slider is horizontally fixed on the bottom surface of the pusher plate 64, and the slider of the pusher plate 64 is horizontally slidably assembled on the slide 61. The slide 61 is used to horizontally fix to the outer wall of the forming mold 5, providing a horizontal guide rail for the pusher plate 64. The pusher plate 64 slides horizontally on the slide 61 through the slider fixed on its bottom surface, and is used to push out the formed workpiece during the shaping process. A pusher motor 62 is horizontally fixed at the end of the slide 61 away from the forming mold 5, and a pusher screw 63 is horizontally fixed at the output end of the pusher motor 62. The pusher motor 62 generates driving force by driving the pusher screw 63. The pusher screw 63 is threadedly assembled with a screw hole plate 65, thereby converting the rotational motion of the motor into the linear motion of the pusher plate 64 through thread transmission. A screw hole plate 65 is horizontally fixed to the end of the pusher plate 64 away from the forming mold 5, and the screw hole plate 65 is threadedly connected to the pusher screw 63. After the pusher motor 62 is started, the pusher motor 62 drives the pusher screw 63 to rotate. The pusher screw 63 pushes the pusher plate 64 to slide along the slide 61 through the threaded engagement with the screw hole plate 65, thereby pushing the workpiece out of the forming mold 5.

[0030] Reference Figure 3A nail plate 11 is horizontally installed below the frame 1, and the nail plate 11 is fixedly assembled with fixing nails. The frame 1, as the overall support structure, provides a stable foundation. The nail plate 11 is fixed to the bottom of the frame with fixing nails, which increases the overall stability and provides an installation position for subsequent components. A support spring 12 is vertically fixed to the top surface of the nail plate 11, and the top end of the support spring 12 is fixed to the bottom surface of the frame 1. The support spring 12 is vertically fixed to the top surface of the nail plate 11, and its top end is connected to the bottom surface of the frame 1. It can provide elastic restoring force when pushed by a slight external force, which helps to absorb shock and return to its original position. A vibration motor 13 is horizontally fixed to the side end face of the frame 1. The vibration motor 13 is installed on the side end face of the frame 1 and can generate vibration to excite the low-frequency vibration of the platform, thereby realizing the uniform distribution of materials or the cleaning function of materials. The frame 1 provides stable support, the nail plate 11 and the support spring 12 form an elastic support system, which effectively absorbs vibration and provides cushioning, while the vibration motor 13 promotes material distribution or cleaning through external vibration.

[0031] The implementation principle of a powder forming hydraulic press with demolding function in this application embodiment is as follows: First, during powder forming and extrusion, powder is loaded onto the top surface of the forming mold 5. The vibration motor 13 on the outside of the frame 1 is started. The vibration generated by the vibration motor 13 causes the support spring 12 between the frame 1 and the nail plate 11 to deform and vibrate. The vibration force causes the powder to fall into the mold cavity 51 of the forming mold 5. The hydraulic rod 4 is started to extend and push the lower pressure plate 3 to slide vertically down on the rod 2. The lower pressure plate 3 compresses the powder and compacts it in the mold cavity 51 of the forming mold 5. At the same time, the extrusion pusher column 55 moves vertically downward in the mold cavity 51 of the forming mold 5, and the return spring 53 on the extrusion bracket 52 deforms. Then, after the powder in the mold cavity 51 of the molding die 5 is formed, the hydraulic rod 4 is activated to extend and push the lower pressure plate 3 to slide vertically upward on the rod frame 2. At this time, under the deformation force of the return spring 53, the pusher plate column 55 pushes the molded powder in the mold cavity 51 of the molding die 5 to slide vertically upward out of the mold cavity 51 of the molding die 5. Finally, the pusher motor 62 on the slide 61 in the pusher component 6 is started. The pusher motor 62 drives the pusher screw 63 to rotate, which drives the screw hole plate 65 on the pusher shovel 64 to move laterally on the slide 61, pushing the molded powder in the mold cavity 51 of the mold 5 to be discharged from the top surface of the mold 5, thus completing the powder molding unloading.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
