Description

Technical Field

[0001] The present invention relates to the technical field of mold manufacturing, and particularly to a part forming mold. Background Art

[0002] In the process of part manufacturing, the forming mold plays an irreplaceable and crucial role. It is not only the core element to ensure the dimensional accuracy and shape accuracy of parts, but also can greatly improve production efficiency and achieve batch manufacturing. At the same time, with advanced mold design and manufacturing processes, parts with complex shapes can be accurately formed to meet the increasingly stringent part requirements in various fields.

[0003] Existing part forming molds expose many problems. One of them is the difficult demolding. Traditional molds have defects in design and structure. After the parts are formed, they often fit tightly with the inner wall of the mold. When demolding, a large amount of manpower and material resources are required. Not only is the efficiency low, but also the formed parts are easily damaged due to the strong pulling during demolding, resulting in a high defective rate, seriously affecting product quality and production efficiency. In addition, the short service life of the mold is also a major problem. Limited by the material properties and processing technology of the mold, after long-term high-frequency use, the mold is prone to wear, deformation and other conditions, and has to be replaced frequently. Frequent mold replacement requires frequent interruption of the production process and re-adjustment of equipment. This process wastes a large amount of time costs and disrupts the production plan, seriously restricting the improvement of part manufacturing efficiency. All these problems are intertwined, severely limiting the further breakthrough of the part manufacturing industry in terms of efficiency and quality, and unable to meet the current needs. Summary of the Invention

[0004] The purpose of the present invention is to provide a part forming mold to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A part forming mold, comprising a base, a guide rod, a top plate, a cylinder, a moving plate, an upper mold base, a fixing device, a conveying device, a lower mold base, and a demolding device. The guide rod is fixedly installed on the top of the base, the top plate is fixedly installed on the top of the guide rod, the cylinder is fixedly installed on the top of the top plate, the moving plate is slidably installed on the surface of the guide rod, the upper mold base is slidably installed inside the moving plate, the fixing device is arranged inside the moving plate, the conveying device is arranged on the surface of the base, the lower mold base is slidably installed inside the base, and the demolding device is arranged at the bottom of the base.

[0006] The fixing device is composed of a fixing rod, an annular sleeve, a first spring, a connecting rod, a limiting block, a linkage rod, and a fixing strip. The fixing rod is fixedly installed inside the moving plate. The annular sleeve is slidably installed on the surface of the fixing rod. The first spring is sleeved on the surface of the fixing rod. The connecting rod is fixedly installed on the surface of the annular sleeve. The limiting block is fixedly installed on the side of the connecting rod. One end of the linkage rod is hinged to the surface of the annular sleeve, and the fixing strip is hinged to the other end of the linkage rod.

[0007] Preferably, the conveying device is composed of a machine base, a motor, a double-groove pulley, a belt, a support leg, a fixing box, a threaded rod, a threaded sleeve, a single-groove pulley, a mounting block, an electric push rod, and a support plate. The machine base is fixedly installed at the bottom of the base. The motor is fixedly installed on the side of the machine base. The double-groove pulley is fixedly installed on the output shaft of the motor. The belt is sleeved on the surface of the double-groove pulley. The support leg is fixedly installed on the top of the base. The fixing box is fixedly installed on the top of the support leg. The threaded rod is rotatably installed inside the fixing box. The threaded sleeve is threadedly installed on the surface of the threaded rod. The single-groove pulley is fixedly installed on the surface of the threaded rod. The mounting block is fixedly installed on the side of the threaded sleeve. The electric push rod is fixedly installed inside the mounting block. The support plate is fixedly installed on the moving end of the electric push rod.

[0008] Preferably, the demoulding device is composed of a moving rod, a movable plate, a fixing plate, a fixing column, a second spring, a support plate, a movable rod, an annular plate, a third spring, and a rectangular block. The moving rod is slidably installed inside the lower die base. The movable plate is slidably installed inside the lower die base. The fixing column is fixedly installed inside the base. The fixing plate is fixedly installed at the bottom of the fixing column. The second spring is sleeved on the surface of the moving rod. The support plate is fixedly installed at the bottom of the base. The movable rod is slidably installed inside the support plate. The annular plate is fixedly installed on the surface of the movable rod. The third spring is sleeved on the surface of the movable rod. The rectangular block is fixedly installed on the side of the movable rod.

[0009] Preferably, one end of the first spring abuts against the moving plate, and the other end abuts against the annular sleeve. When the annular sleeve is displaced due to an external force, the first spring will be compressed to store elastic potential energy. Once the external force disappears, the first spring quickly releases energy by virtue of its own elasticity to reset the annular sleeve and make it return to its initial position.

[0010] Preferably, fixing devices are provided inside both the base and the moving plate, and limiting grooves matching the limiting blocks are provided inside both the upper die base and the lower die base. When installing the upper die base and the lower die base, by accurately inserting the limiting blocks into the preset limiting grooves of the upper die base and the lower die base, the upper die base and the lower die base can be firmly fixed together to avoid displacement deviation during the stamping operation.

[0011] Preferably, the double-groove pulley, the belt and the single-groove pulley are drivingly connected. In this drive system, the motor serves as the core power source, providing continuous power for the operation of the entire mechanism. After the motor is started, its high-speed rotating output shaft drives the closely connected double-groove pulley to rotate synchronously. The double-groove pulley transmits power to the single-groove pulley smoothly and efficiently through the belt. After receiving the power, the single-groove pulley further drives the threaded rod to start rotating by virtue of its rigid connection with the threaded rod.

[0012] Preferably, the movable plate is threadedly installed on the top of the movable rod. A chute matching the rectangular block is provided inside the movable rod. By threadedly installing the movable plate on the top of the movable rod, when it is necessary to disassemble the movable plate, simply rotate the movable plate to quickly disassemble the movable plate from the top of the movable rod, facilitating the subsequent disassembly operation of the lower die holder. Inside the movable rod, the provided chute ensures that the rectangular block can slide easily and stably therein, providing a strong guarantee for the precise operation of the equipment.

[0013] Preferably, one end of the second spring is fixedly connected to the movable rod, and the other end of the second spring abuts against the fixed plate. When the movable rod is displaced due to an external force, the second spring will be stretched to store elastic potential energy. Once the external force disappears, the second spring quickly releases energy by virtue of its own elasticity to reset the movable rod to its initial position.

[0014] Preferably, one end of the third spring abuts against the support plate, and the other end of the third spring abuts against the annular plate. A pull ring is fixedly installed on the side surface of the movable rod. When the movable rod is displaced due to an external force, the third spring will be stretched to store elastic potential energy. Once the external force disappears, the third spring quickly releases energy by virtue of its own elasticity to reset the movable rod to its initial position. When holding the pull ring by hand and applying a pulling force, the pull ring transmits the pulling force to the movable rod through its connecting component with the movable rod, thereby driving the movable rod to move smoothly along the established track.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) By starting the electric push rod to adjust the distance between the two support plates, placing the part to be processed on the surfaces of the two support plates, driving the motor, its high-speed rotating output shaft drives the closely connected double-groove pulley to rotate synchronously. The double-groove pulley transmits power to the single-groove pulley smoothly and efficiently through the belt. After receiving the power, the single-groove pulley further drives the threaded rod to start rotating by virtue of its rigid connection with the threaded rod. Under the action of the threaded sleeve and the mounting block, the support plate can be moved, and the part to be processed can be conveyed to the top of the lower die holder, which is convenient to use.

[0016] (2) The part forming die starts the cylinder to drive the moving plate and the upper die base to move downward until the moving plate abuts against the fixed column. Then, the cylinder is started again to drive the moving plate and the upper die base to move upward and reset. Under the combined action of the upper die base and the lower die base, the part to be processed can be stamped and formed. During this process, the movable plate drives the moving rod to move downward first and compress the second spring. Then, the second spring quickly releases energy by its own elasticity to reset the moving rod, so that the movable plate returns to the initial position and ejects the processed part, with good use effect.

[0017] (3) When the pull ring is held by hand and a pulling force is applied, the movable rod drives the rectangular block to move and disengage from the chute. The second spring further resets the moving rod by its own elasticity, enabling the movable plate to be higher than the top of the lower die base. Rotating the movable plate can disassemble the movable plate from the top of the moving rod, facilitating the subsequent disassembly of the lower die base.

[0018] (4) By moving the fixed strip, under the action of the linkage rod, the annular sleeve can drive the connecting rod to slide on the surface of the fixed rod, enabling the limiting block to disengage from the limiting groove, and the lower die base can be disassembled from the inside of the base. Similarly, the upper die base can be disassembled from the inside of the moving plate, and the upper die base and the lower die base can be replaced, with strong practicability.

One end of the first spring 703 abuts against the moving plate 5, and the other end of the first spring 703 abuts against the annular sleeve 702. When the annular sleeve 702 is displaced due to an external force, the first spring 703 will be compressed to store elastic potential energy. Once the external force disappears, the first spring 703 quickly releases energy by virtue of its own elasticity to reset the annular sleeve 702 and make it return to its initial position. The connecting rod 704 is fixedly installed on the surface of the annular sleeve 702. The limiting block 705 is fixedly installed on the side of the connecting rod 704. The fixing device 7 is provided inside both the base 1 and the moving plate 5. Limiting grooves matching the limiting block 705 are provided inside both the upper die base 6 and the lower die base 9. When the upper die base 6 and the lower die base 9 are installed, by accurately inserting the limiting block 705 into the preset limiting grooves of the upper die base 6 and the lower die base 9, the upper die base 6 and the lower die base 9 can be firmly fixed together to avoid displacement deviation during the stamping operation. One end of the linkage rod 706 is hinged to the surface of the annular sleeve 702, and the fixing strip 707 is hinged to the other end of the linkage rod 706.

[0024] The conveying device 8 is composed of a machine base 801, a motor 802, a double-groove pulley 803, a belt 804, support legs 805, a fixed box 806, a threaded rod 807, a threaded sleeve 808, a single-groove pulley 809, a mounting block 810, an electric push rod 811, and a support plate 812. The machine base 801 is fixedly installed at the bottom of the base 1, the motor 802 is fixedly installed on the side of the machine base 801, the double-groove pulley 803 is fixedly installed on the output shaft of the motor 802, the belt 804 is sleeved on the surface of the double-groove pulley 803, the support legs 805 are fixedly installed on the top of the base 1, the fixed box 806 is fixedly installed on the top of the support legs 805, the threaded rod 807 is rotatably installed inside the fixed box 806, the threaded sleeve 808 is threadedly installed on the surface of the threaded rod 807, the single-groove pulley 809 is fixedly installed on the surface of the threaded rod 807, and the double-groove pulley 803, the belt 804, and the single-groove pulley 809 are in transmission connection. In this transmission system, the motor 802 serves as the core power source, providing continuous power for the operation of the entire mechanism. After the motor 802 is started, its high-speed rotating output shaft drives the closely connected double-groove pulley 803 to rotate synchronously. The double-groove pulley 803 smoothly and efficiently transmits the power to the single-groove pulley 809 through the belt 804. After receiving the power, the single-groove pulley 809 further drives the threaded rod 807 to start rotating by virtue of its rigid connection with the threaded rod 807. The mounting block 810 is fixedly installed on the side of the threaded sleeve 808, the electric push rod 811 is fixedly installed inside the mounting block 810, and the support plate 812 is fixedly installed on the mobile end of the electric push rod 811.

[0025] The demolding device 10 is composed of a moving rod 1001, a movable plate 1002, a fixed plate 1003, a fixed column 1004, a second spring 1005, a support plate 1006, a movable rod 1007, an annular plate 1008, a third spring 1009, and a rectangular block 1010. The moving rod 1001 is slidably installed inside the lower mold base 9, the movable plate 1002 is slidably installed inside the lower mold base 9, the fixed column 1004 is fixedly installed inside the base 1, the fixed plate 1003 is fixedly installed at the bottom of the fixed column 1004, the second spring 1005 is sleeved on the surface of the moving rod 1001, one end of the second spring 1005 is fixedly connected to the moving rod 1001, and the other end of the second spring 1005 abuts against the fixed plate 1003. When the moving rod 1001 generates displacement due to an external force, the second spring 1005 will be stretched to store elastic potential energy. Once the external force disappears, the second spring 1005 quickly releases energy by virtue of its own elasticity to reset the moving rod 1001 to its initial position. The support plate 1006 is fixedly installed at the bottom of the base 1, the movable rod 1007 is slidably installed inside the support plate 1006, the annular plate 1008 is fixedly installed on the surface of the movable rod 1007, the third spring 1009 is sleeved on the surface of the movable rod 1007, one end of the third spring 1009 abuts against the support plate 1006, and the other end of the third spring 1009 abuts against the annular plate 1008. A pull ring is fixedly installed on the side of the movable rod 1007. When the movable rod 1007 generates displacement due to an external force, the third spring 1009 will be stretched to store elastic potential energy. Once the external force disappears, the third spring 1009 quickly releases energy by virtue of its own elasticity to reset the movable rod 1007 to its initial position. When holding the pull ring by hand and applying a pulling force, the pull ring transmits the pulling force to the movable rod 1007 through its connecting component with the movable rod 1007, thereby driving the movable rod 1007 to move smoothly along the established track. The rectangular block 1010 is fixedly installed on the side of the movable rod 1007, the movable plate 1002 is threadedly installed on the top of the moving rod 1001, and a chute matching the rectangular block 1010 is opened inside the moving rod 1001. By threadedly installing the movable plate 1002 on the top of the moving rod 1001, when it is necessary to disassemble the movable plate 1002, simply rotate the movable plate 1002 to quickly disassemble the movable plate 1002 from the top of the moving rod 1001, facilitating the subsequent disassembly operation of the lower mold base 9. Inside the moving rod 1001, the opened chute ensures that the rectangular block 1010 can slide easily and stably therein, providing a strong guarantee for the precise operation of the device.

[0026] During use, start the electric push rod 811 to adjust the distance between the two support plates 812. Place the part to be processed on the surfaces of the two support plates 812. Drive the motor 802. The output shaft rotating at high speed drives the double-groove pulley 803 tightly connected thereto to rotate synchronously. The double-groove pulley 803 transmits power smoothly and efficiently to the single-groove pulley 809 through the belt 804. After receiving the power, the single-groove pulley 809 drives the threaded rod 807 to start rotating by virtue of its rigid connection with the threaded rod 807. Under the action of the threaded sleeve 808 and the mounting block 810, the support plate 812 can be moved, and the part to be processed can be conveyed to the top of the lower die base 9. Start the cylinder 4 to make the moving plate 5 drive the upper die base 6 to move downward until the moving plate 5 abuts against the fixed column 1004. Then start the cylinder 4 again to make the moving plate 5 drive the upper die base 6 to move upward and reset. Under the combined action of the upper die base 6 and the lower die base 9, the part to be processed can be subjected to a stamping and forming operation. During this process, the movable plate 1002 drives the moving rod 1001 to move downward first and compress the second spring 1005. Then the second spring 1005 quickly releases energy by virtue of its own elasticity to reset the moving rod 1001, so that the movable plate 1002 returns to its initial position and ejects the processed part. When holding the pull ring by hand and applying a pulling force, the movable rod 1007 drives the rectangular block 1010 to move and disengage from the chute. The second spring 1005 further resets the moving rod 1001 by virtue of its own elasticity, so that the movable plate 1002 can be higher than the top of the lower die base 9. Rotating the movable plate 1002 can detach the movable plate 1002 from the top of the moving rod 1001. Move the fixed strip 707. Under the action of the linkage rod 706, the annular sleeve 702 can drive the connecting rod 704 to slide on the surface of the fixed rod 701, so that the limiting block 705 disengages from the limiting groove, and the lower die base 9 can be detached from the inside of the base 1. Similarly, the upper die base 6 can be detached from the inside of the moving plate 5, and the upper die base 6 and the lower die base 9 can be replaced.
