Description

Technical Field

[0001] This invention relates to the field of cup processing technology, and more specifically to a mold hammering device for cup forming. Background Technology

[0002] The current teacup manufacturing process does indeed have some problems, the most significant being low production efficiency. Traditional teacup making involves placing the teacup blank into a mold, then striking and pressing it with a plumb bob to form the cup. This process is not only time-consuming and labor-intensive but also requires a large amount of manual operation, resulting in low production efficiency and high production costs.

[0003] To improve production efficiency, existing pressing machines use stamping cylinders to replace simple, repetitive actions. Existing technology includes a patent with authorization publication number CN220030577U, which discloses a high-temperature resistant pressing machine, including a fixed platform with a support arm fixedly mounted on the left side of the platform, and a stamping cylinder fixedly mounted on the top of the support arm. This machine only uses the cylinder's simple extension and retraction to press, making it difficult to precisely control the magnitude and direction of the impact force. This may result in insufficient forming precision of the teacup, unstable surface quality, and uneven impact due to the fixed-surface impact. Furthermore, it cannot provide assisted demolding, leading to low processing efficiency. Summary of the Invention

[0004] This invention provides a mold hammering device for cup forming, in order to solve the technical problems of slow cup forming efficiency and low precision and poor consistency of finished products.

[0005] To solve the above problems, the mold hammering device for cup forming processing provided by the present invention adopts the following technical solution:

[0006] The device includes a work platform, on which a positioning mechanism for positioning mold components is provided. Above the work platform are an impact mechanism for hammering the mold components and a lifting mechanism for assisting in demolding the mold components. The work platform is also provided with a reciprocating drive mechanism for driving the impact mechanism to move up and down.

[0007] The reciprocating drive mechanism includes a rotating shaft and a drive component that drives the rotating shaft to rotate. A cam component is provided at one end of the rotating shaft that is close to the impact mechanism. The rotating shaft rotates and drives the cam component to rotate. A frame assembly is provided on the work platform, and the drive component is supported by the frame assembly.

[0008] The impact mechanism includes an impact rod and a rotating impact assembly located at the lower end of the impact rod. The top of the impact rod is provided with a counterweight plate. A pin is provided on the side of the impact rod that is close to the cam component. A wheel that cooperates with the cam component is provided on the pin. The cam component and the wheel cooperate to drive the impact rod to move up and down reciprocally. A guide assembly that cooperates with the impact rod is provided on the frame assembly.

[0009] Using the above technical solution, the cam component and the wheel work together to drive the impact rod to move up and down reciprocally, ultimately moving the impact rod up and down to impact the mold, thereby achieving the forming process of the cup. Automatic hammering can quickly complete the forming process of the purple clay cup in a short time, which greatly improves production efficiency, reduces the labor intensity of workers, and reduces the impact of human factors on product quality, thereby improving the product qualification rate.

[0010] In addition, the more uniform deformation of the blank within the mold assembly by using the rotating impact component helps to reduce internal stress and lower the risk of material cracking or deformation.

[0011] The positioning mechanism includes a tooling table on the work platform, and two sets of clamping components are provided on the tooling table. The two sets of clamping components are connected by an arc-shaped channel. A mold ejection component is provided below the clamping component away from the impact rod, and the lifting mechanism is correspondingly provided above the mold ejection component.

[0012] Two clamping stations are formed by two sets of clamping components and are connected. One station corresponds to the impact mechanism and the other corresponds to the lifting mechanism. Since there are two clamping stations, the operator can choose to perform the impact processing first and then the lifting operation as needed, which improves the flexibility of operation. Since the two stations are connected, the mold assembly can be transferred to the other station for lifting operation immediately after the impact processing is completed at one station, which further improves the production efficiency.

[0013] Furthermore, the impact rod includes a square column section and a first cylindrical section located at the top of the square column section. The outer wall of the first cylindrical section is threaded, and the counterweight plate is placed on the first cylindrical section and secured by a nut.

[0014] By adopting the above technical solution, the weight of the counterweight plate can be adjusted by adjusting the nut, thereby achieving precise control of the impact force, meeting the impact force requirements of different processing needs, and improving the flexibility and adaptability of processing.

[0015] Furthermore, a second cylindrical section is provided below the square column section to cooperate with the rotating impact assembly. The rotating impact assembly includes a cylindrical sleeve with a punch at the bottom end. The cylindrical sleeve is rotatably fitted onto the second cylindrical section through two deep groove bearings spaced apart vertically. A boss is provided at the end of the second cylindrical section that is close to the square column section. The diameter of the boss is larger than the diameter of the second cylindrical section. A thrust ball bearing is fitted onto the boss.

[0016] The outer wall of the cylindrical sleeve is provided with a steering guide groove, which includes an upper guide groove and a lower guide groove. The bottom end of the upper guide groove is provided with a first inclined guide surface opposite to the lower guide groove, and the top end of the lower guide groove is provided with a second inclined guide surface opposite to the upper guide groove. A guide shaft that cooperates with the steering guide groove is fixed on the frame assembly. While the cylindrical sleeve moves up and down, the guide shaft moves between the upper guide groove and the lower guide groove and drives the cylindrical sleeve to rotate through the action of the first inclined guide surface and the second inclined guide surface.

[0017] By adopting the above technical solution, the cylindrical sleeve is rotated and supported by a deep groove bearing, which improves the stability and accuracy of rotational impact, thereby improving the processing quality and efficiency. A thrust ball bearing is installed on the boss, so that the thrust ball bearing is located between the lower end face of the square column section and the upper end face of the cylindrical sleeve. The thrust ball bearing can withstand a large axial load and has high rotational accuracy and low frictional resistance, which can improve the service life and efficiency of the rotational impact assembly.

[0018] In addition, by using the steering guide groove in conjunction with the guide shaft, the cylindrical sleeve gradually rotates as the impact rod moves up and down. The rotation is achieved through mechanical means without the need for additional power, which reduces the potential dangers during operation, improves the utilization rate of the equipment, and enhances its safety.

[0019] Furthermore, the frame assembly includes a vertical plate disposed on one side of the impact rod, and the guide shaft is fixed to the vertical plate.

[0020] The guide assembly includes a support shaft fixed to the upright plate, and an I-shaped guide wheel is rotatably sleeved on the support shaft. The I-shaped guide wheel is used to assist the square column section of the impact rod in achieving vertical straight guidance.

[0021] By adopting the above technical solution, the guiding effect of the I-shaped guide wheel helps to improve the stability of the impact rod during axial movement, thereby improving the overall structural stability during operation, which helps to extend the service life of the equipment and reduce maintenance costs and time.

[0022] Furthermore, the lifting mechanism includes a support rod and a telescopic member vertically disposed at the end of the support rod. The drive rod end of the telescopic member is detachably provided with a magnetic attraction assembly. The magnetic attraction assembly includes a fixing plate and a connecting member fixed by the fixing plate. The bottom end of the connecting member is provided with a magnet.

[0023] By adopting the above technical solution, the magnetic suction component is driven to rise and fall by the telescopic action of the telescopic rod, thereby enabling the upper mold of the mold component to be removed by the magnetic suction component. Then, the finished product can be ejected by the ejection component. The removal of the upper mold by the magnetic suction component can ensure the safety and stability of the operation process and reduce the possible dangers during the operation.

[0024] Furthermore, the tooling table includes a buffer frame fixed to the work platform by rubber shock absorbers. A circular groove is formed on the upper end surface of the buffer frame. A fan-shaped plate is provided in the circular groove and is fixedly supported by an auxiliary plate fixed to the bottom surface of the buffer frame. There is a gap between adjacent fan-shaped plates. The arc-shaped channel is formed between the fan-shaped plate and the upper panel of the buffer frame. A vibration component for driving the tooling table to vibrate is provided on the work platform.

[0025] Furthermore, the clamping assembly includes a fixed clamping block that is adjustable and fixed to the upper surface of the buffer platform and a movable V-shaped clamping block that is disposed opposite to the fixed clamping block. The bottom surface of the buffer platform is provided with a cylinder for driving the movable V-shaped clamping block to move.

[0026] By adopting the above technical solution, the buffer frame is fixed to the work platform using rubber shock absorbers, which reduces the vibration and impact generated during equipment operation and improves the stability and reliability of the equipment. In addition, the tooling table has strong overall flexibility and adaptability, and can be quickly adjusted according to different production needs and mold sizes by using clamping components.

[0027] Furthermore, the vibration assembly includes a pneumatic gear vibrator, which is fixed to the carrier plate. The working platform is provided with a slot corresponding to the carrier plate and allowing the carrier plate to pass through. Each of the four corners of the carrier plate is provided with a column. The column corresponding to the fan-shaped plate vertically penetrates the bottom surface of the buffer frame and is fixedly connected to the fan-shaped plate. The column corresponding to the top surface of the buffer frame vertically penetrates the bottom surface of the buffer frame and is fixedly connected to the top surface of the buffer frame.

[0028] Using the above technical solution, during the impact of the impact rod on the mold assembly, the vibration component drives the mold assembly to achieve micro-vibration as needed. This micro-vibration increases the fluidity of the material during the molding process, allowing it to better fill the mold cavity and helping to improve the material's density and the uniformity of its microstructure. Furthermore, micro-vibration reduces stress concentration within the material during mold forming, lowering the risk of cracking. It also improves surface quality: micro-vibration helps reduce the surface roughness of the molded part, thus improving its surface quality.

[0029] In addition, during the demolding process of the mold assembly, micro-vibration can help the material to be smoothly ejected from the mold, reduce the demolding force, and prevent the product from being damaged during demolding.

[0030] The carrier plates are located below the two sets of clamping assemblies respectively. The ejection assembly is located below the carrier plate corresponding vertically to the lifting mechanism. The ejection assembly includes a hinged connector with a connecting shaft on it. An ejection rod is connected to the connecting shaft via a coupling. The other end of the hinged connector is hinged to the action lever. A connecting rod is hinged to the lower surface of the work platform, and the other end of the connecting rod is hinged to the corresponding action lever.

[0031] By adopting the above technical solution, the ejector rod moves up and down in conjunction with the lever action. When ejecting upwards, the finished product is removed from the mold. The operation is simple, and the ejector rod can quickly and accurately complete the upward movement, thereby efficiently removing the finished product from the mold and improving the production efficiency of the equipment.

[0032] Furthermore, the frame assembly is also supported by an auxiliary lifting component, which includes a side bracket and a vertical pole that is rotatably supported by the side bracket. The vertical pole is provided with a lifting assembly frame, and the free end of the lifting assembly frame is provided with a magnetic attraction assembly frame. The magnetic attraction assembly frame includes a vertical rod fixed to one end of the lifting assembly frame, and the bottom end of the vertical rod is provided with a magnetic attraction block.

[0033] Furthermore, the lifting assembly includes two parallel hinge rods arranged at the top and bottom. Both ends of the hinge rods are hinged with U-shaped groove plates. The U-shaped groove plate at the end of the hinge rod that is close to the upright is fixed to the side of the upright. The end of the upper hinge rod that is away from the upright is provided with a side plate. A gas spring is hinged between the side plate and the U-shaped groove plate fixed to the side of the upright.

[0034] When using the above technical solution, in situations such as maintenance and upkeep of the lifting mechanism, an auxiliary lifting component can be used to assist in demolding. That is, the upper mold of the mold assembly is removed by a magnetic block, and then the finished product is ejected by the ejection component. The setting of the auxiliary lifting component improves the flexibility of the overall structure.

[0035] The beneficial effects of the mold hammering device for cup forming provided by this invention are as follows: This device can quickly complete the forming process of purple clay cups in a short time through a more uniform automatic hammering method, greatly improving production efficiency. Furthermore, the rotating impact component allows the blank to deform more uniformly within the mold component, helping to reduce internal stress and improve product stability and durability. In addition, the demolding process is simple to operate and highly safe and flexible, further improving production efficiency. Attached Figure Description

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0051] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0052] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0053] Embodiment 1 of the mold hammering device for cup forming process provided by the present invention:

[0054] like Figures 1 to 11 As shown,

[0055] The device includes a work platform 1, on which a positioning mechanism 2 for positioning a mold assembly 9 is provided. Above the work platform 1, there is an impact mechanism 3 for hammering the mold assembly 9 and a lifting mechanism 4 for assisting the demolding of the mold assembly 9. The work platform 1 is also provided with a reciprocating drive mechanism 5 for driving the impact mechanism 3 to move up and down.

[0056] The reciprocating drive mechanism 5 includes a rotating shaft 51 and a drive component 52 that drives the rotating shaft 51 to rotate. The drive component 52 is a motor. The rotating shaft 51 is provided with a cam component 53 at one end close to the impact mechanism 3. The rotating shaft 51 rotates and drives the cam component 53 to rotate. The work platform 1 is provided with a frame assembly 6, and the drive component 52 is supported by the frame assembly 6.

[0057] The impact mechanism 3 includes an impact rod 31 and a rotating impact assembly 32 located at the lower end of the impact rod 31. The top end of the impact rod 31 is provided with a counterweight plate 33. A pin 34 is provided on the side of the impact rod 31 that is close to the cam member 53. A wheel 35 that cooperates with the cam member 53 is provided on the pin 34. The cam member 53 and the wheel 35 cooperate to drive the impact rod 31 to move up and down reciprocally. A guide assembly that cooperates with the impact rod 31 is provided on the frame assembly.

[0058] In this embodiment, the cam 53 and the wheel 35 work together to drive the impact rod 31 to move up and down reciprocally, ultimately driving the impact rod 31 to move up and down to impact the mold, thereby realizing the forming process of the cup. Automatic hammering can quickly complete the forming process of the purple clay cup in a short time, which greatly improves production efficiency, reduces the labor intensity of workers, and reduces the impact of human factors on product quality, thereby improving the product qualification rate.

[0059] In addition, the more uniform deformation of the blank within the mold assembly 9 achieved by the rotating impact component 32 helps to reduce internal stress and lower the risk of material cracking or deformation.

[0060] The positioning mechanism 2 includes a tooling table 21 on the work platform 1. The tooling table 21 is provided with two sets of clamping components 22. The two sets of clamping components 22 are connected by an arc-shaped channel 23. A mold ejection component is provided below the clamping component 22 away from the impact rod 31. The lifting mechanism 4 is correspondingly provided above the mold ejection component.

[0061] Two clamping stations are formed by two sets of clamping components 22, and the two clamping stations are connected. One station corresponds to the impact mechanism 3, and the other corresponds to the lifting mechanism 4. Since there are two clamping stations, the operator can choose to perform the impact processing first and then the lifting operation as needed, which improves the flexibility of operation. Since the two stations are connected, the mold component 9 can be transferred to the other station for lifting operation immediately after the impact processing is completed at one station, which further improves the production efficiency.

[0062] The impact rod 31 includes a square column section 311 and a first cylindrical section 312 located at the top of the square column section 311. The outer wall of the first cylindrical section 312 is threaded. The counterweight plate 33 is placed on the first cylindrical section 312 and fastened by a nut.

[0063] In this embodiment, the weight of the counterweight plate 33 is adjusted by adjusting the nut, thereby achieving precise control of the impact force, meeting the impact force requirements of different processing needs, and improving the flexibility and adaptability of processing.

[0064] Furthermore, a second cylindrical section 313 is provided below the square column section 311 to cooperate with the rotating impact assembly 32. The rotating impact assembly 32 includes a cylindrical sleeve 321. The bottom end of the cylindrical sleeve 321 is provided with a punch 322. The cylindrical sleeve 321 is rotatably sleeved on the second cylindrical section 313 through two deep groove bearings 323 spaced apart vertically. The end of the second cylindrical section 313 that is close to the square column section 311 is provided with a boss 314. The diameter of the boss 314 is larger than the diameter of the second cylindrical section 313. A thrust ball bearing 315 is sleeved on the boss 314.

[0065] The outer wall of the cylindrical sleeve 321 is provided with a steering guide groove 324. The steering guide groove 324 includes an upper guide groove 3241 and a lower guide groove 3243. The bottom end of the upper guide groove 3241 is provided with a first inclined guide surface 3242 opposite to the lower guide groove 3243. The top end of the lower guide groove 3243 is provided with a second inclined guide surface 3244 opposite to the upper guide groove 3241. A guide shaft that cooperates with the steering guide groove 324 is fixed on the frame assembly 6. While the cylindrical sleeve 321 moves up and down, the guide shaft moves between the upper guide groove 3241 and the lower guide groove 3243 and drives the cylindrical sleeve 321 to rotate through the action of the first inclined guide surface 3242 and the second inclined guide surface 3244.

[0066] In this embodiment, a deep groove bearing 323 is disposed between the inner wall of the cylindrical sleeve 321 and the outer wall of the second cylindrical section 313. The deep groove bearing 323 provides rotational support for the cylindrical sleeve 321, improving the stability and accuracy of rotational impact, thereby improving processing quality and efficiency. A thrust ball bearing 315 is disposed on the boss 314, so that the thrust ball bearing 315 is located between the lower end face of the square column section 311 and the upper end face of the cylindrical sleeve 321. The thrust ball bearing 315 can withstand a large axial load and has high rotational accuracy and low frictional resistance, which can improve the service life and efficiency of the rotational impact assembly 32.

[0067] In addition, by using the steering guide groove 324 in conjunction with the guide shaft 621, the cylindrical sleeve 321 is driven to rotate gradually while the impact rod 31 moves up and down. The rotation is achieved through mechanical cooperation without the need for additional power, which reduces the potential dangers during operation, improves the utilization rate of the equipment, and enhances the safety of the equipment.

[0068] The frame assembly 6 includes a vertical plate 62 located on one side of the impact rod 31, and the guide shaft 621 is fixed on the vertical plate 62.

[0069] The guide assembly 61 includes a support shaft 611 fixed on the upright plate 62, and an I-shaped guide wheel 612 is rotatably sleeved on the support shaft 611. The I-shaped guide wheel 612 is used to assist the square column section 311 of the impact rod 31 in achieving vertical straight guidance.

[0070] In this embodiment, the guiding effect of the I-shaped guide wheel 612 helps to improve the stability of the impact rod 31 during axial movement, thereby improving the overall structural stability and helping to extend the service life of the equipment and reduce maintenance costs and time.

[0071] The lifting mechanism 4 includes a support rod 41 and a telescopic member 42 vertically disposed at the end of the support rod 41. A magnetic attraction assembly 43 is detachably provided at the end of the drive rod of the telescopic member 42. The magnetic attraction assembly 43 includes a fixing plate 431 and a connecting member 432 fixed by the fixing plate 431. A magnet 433 is provided at the bottom end of the connecting member 432. In this embodiment, the telescopic member 42 can be a cylinder.

[0072] In this embodiment, the support rod 41 can be cut from a high-purity magnesium alloy rod. The support rod 41, made from a high-purity magnesium alloy rod, has the advantages of corrosion resistance, high flexibility, and resistance to deformation under arbitrary bending. In actual use, the support rod 41 can undergo a certain degree of deformation under external force without easily breaking, thereby improving its service life and safety.

[0073] In this embodiment, the magnetic suction component is driven to rise and fall by the extension and retraction of the telescopic rod, thereby removing the upper mold of the mold component 9 through the magnetic suction component. Then, the finished product is ejected by the ejection component. The removal of the upper mold is completed by the lifting and lowering of the magnetic suction component 43, which can ensure the safety and stability of the operation process and reduce the possible dangers during the operation.

[0074] In this embodiment, the mold assembly 9 includes an upper mold, a lower mold, and an ejector located at the bottom of the lower mold. The upper cross section of the ejector is trapezoidal, meaning that the ejector can only move upward relative to the lower mold and be pushed out.

[0075] The tooling table 21 includes a buffer frame 212 fixed to the work platform 1 by a rubber shock absorber 211. The upper end surface of the buffer frame 212 has a circular groove 2121. A fan-shaped plate 2123 is fixedly supported by an auxiliary plate 2122 fixed to the bottom surface of the buffer frame 212 within the circular groove 2121. There is a gap between adjacent fan-shaped plates 2123. The arc-shaped channel 23 is formed between the fan-shaped plate 2123 and the upper panel of the buffer frame 212. The work platform 1 is provided with a vibration assembly 11 for driving the tooling table 21 to vibrate.

[0076] The clamping assembly 22 includes a fixed clamping block 221 that is adjustable and fixed to the upper surface of the buffer platform 212 and a movable V-shaped clamping block 222 that is disposed opposite to the fixed clamping block 221. The bottom surface of the buffer platform 212 is provided with a cylinder 223 for driving the movable V-shaped clamping block 222 to move.

[0077] The buffer frame 212 is fixed to the work platform 1 by the rubber shock absorber 211, which can reduce the vibration and impact generated during the operation of the equipment and improve the stability and reliability of the equipment. In addition, the tooling table 21 has strong overall flexibility and adaptability, and can be quickly adjusted according to different production needs and mold sizes by using the clamping assembly 22.

[0078] The vibration assembly 11 includes a pneumatic gear vibrator 111, which is fixed on the carrier plate 112. The work platform 1 is provided with a slot 12 corresponding to the carrier plate 112 and allowing the carrier plate 112 to pass through. Each of the four corners of the carrier plate 112 is provided with a column 113. The column 113 corresponding to the fan-shaped plate 2123 vertically penetrates the bottom surface of the buffer platform 212 and is fixedly connected to the fan-shaped plate 2123. The column 113 corresponding to the top surface of the buffer platform 212 vertically penetrates the bottom surface of the buffer platform 212 and is fixedly connected to the top surface of the buffer platform 212.

[0079] In this embodiment, during the impact of the impact rod 31 on the mold assembly 9, the vibration assembly 11 drives the mold assembly 9 to achieve micro-vibration as needed. Micro-vibration increases the fluidity of the material during the molding process, allowing it to better fill the mold cavity, which helps improve the material's density and the uniformity of its microstructure. Furthermore, micro-vibration reduces stress concentration within the material during molding, lowering the risk of cracking. It also improves surface quality: micro-vibration helps reduce the surface roughness of the molded part, thus improving its surface quality.

[0080] In addition, during the demolding process of mold assembly 9, micro-vibration can help the material to be smoothly ejected from the mold, reduce the demolding force, and prevent the product from being damaged during the demolding process.

[0081] The carrier plate 112 is located below the two sets of clamping components 22 respectively. The ejection component 7 is located below the carrier plate 112, which is vertically corresponding to the lifting mechanism 4. The ejection component 7 includes a hinged connector 71. The hinged connector 71 is provided with a connecting shaft 72. The connecting shaft 72 is connected to an ejection rod 74 through a coupling 73. The other end of the hinged connector 71 is hinged to an action lever 75. The lower surface of the work platform 1 is hinged to a connecting rod 76. The other end of the connecting rod 76 is hinged to the corresponding action lever 75.

[0082] The ejector rod 74 moves up and down in conjunction with the lever 75. When ejecting upwards, the finished product is removed from the mold. The operation is simple, and the ejector rod 74 can move upwards quickly and accurately, thereby efficiently removing the finished product from the mold and improving the production efficiency of the equipment.

[0083] The frame assembly 6 is further supported by an auxiliary lifting component 8, which includes a side bracket 81 and a vertical rod 82 rotatably supported by the side bracket 81. Specifically, a bushing is provided at the end of the side bracket 81 away from the frame assembly 6, and the bottom end of the vertical rod 82 is rotatably mounted in the bushing via a bearing.

[0084] The upright 82 is provided with a lifting assembly frame 83, and the free end of the lifting assembly frame 83 is provided with a magnetic attraction assembly frame. The magnetic attraction assembly frame includes a vertical rod 84 fixed to one end of the lifting assembly frame 83, and the bottom end of the vertical rod 84 is provided with a magnetic attraction block 85.

[0085] The lifting assembly frame 83 includes two parallel hinge rods 831 arranged at the top and bottom. Both ends of the hinge rods 831 are hinged with U-shaped groove plates 832. The U-shaped groove plate 832 at the end of the hinge rod 831 that is close to the upright 82 is fixed to the side of the upright 82. The end of the upper hinge rod 831 that is away from the upright 82 is provided with a side plate 833. A gas spring 834 is hinged between the side plate 833 and the U-shaped groove plate 832 fixed to the side of the upright 82.

[0086] In cases of maintenance of the lifting mechanism 4, an auxiliary lifting component 8 can be used to assist in demolding. That is, the upper mold of the mold component 9 is removed by a magnetic block, and then the finished product is ejected by the ejection component. The setting of the auxiliary lifting component 8 improves the flexibility of the overall structure.

[0087] Specifically, when the lifting mechanism 4 is not in use, it can be adjusted to one side by the support rod 41, and then the magnetic combination frame can be rotated by the upright rod 82 to rotate above the mold component 9 that needs to be demolded. Then, the upper mold component can be removed by the action of the lifting combination frame 83 and the magnetic block 85.

[0088] In practical use, the blank is manually placed into the mold assembly 9, and then the mold assembly 9 is placed on the tooling table 21, corresponding to the bottom of the impact rod 31, and held and fixed by the clamping assembly 22. The cam 53 and the wheel 35 work together to drive the impact rod 31 to move up and down reciprocally, thereby realizing the forming process of the cup. During the up and down movement of the impact rod 31, the guide groove 324 works with the guide shaft to drive the cylindrical sleeve 321 to gradually rotate, so that the blank is deformed more evenly in the mold assembly 9, which helps to reduce internal stress and reduce the risk of material cracking or deformation. At the same time, the vibration assembly 11 can drive the mold assembly 9 to achieve micro-vibration as needed. Micro-vibration can increase the fluidity of the material during the forming process, allowing it to better fill the mold cavity, which helps to improve the density and uniformity of the material structure.

[0089] When the cup needs to be demolded after it has been formed, the mold assembly 9 is moved to the bottom of the lifting mechanism 4. The upper mold part is moved away by the lifting mechanism 4, and then the formed cup is ejected by the ejection assembly 7, thus achieving demolding. The operation is simple and the overall use is highly flexible. In addition, when the mold assembly 9 is demolding, the corresponding vibration assembly 11 micro-vibrates to help the material get out of the mold smoothly, reduce the demolding force, and avoid damage to the product during the demolding process.
