Description

Technical Field

[0001] This utility model relates to the field of workpiece shaping technology, and in particular to a workpiece shaping mold for rapid demolding. Background Technology

[0002] Workpiece shaping refers to the finishing or correction operations performed after machining and manufacturing to ensure that the shape, size, positional accuracy, or surface quality of the workpiece meets the final design requirements. Its core purpose is to correct deformations, errors, or defects generated during machining or processing, and to ensure that the workpiece meets the requirements of drawings or process specifications.

[0003] In existing workpiece shaping processes, the workpiece is placed into the mold groove inside the lower mold by a feeding device, and then the upper mold is pressed down, so that the upper mold and the lower mold cooperate to shape the workpiece and ensure that the shape of the workpiece meets the specified requirements.

[0004] Existing forming molds mainly achieve forming through the cooperation of upper and lower molds. The lower mold usually has a demolding component inside. However, when the workpiece being formed is small, the traditional ejector pin structure directly ejects the workpiece, which will cause damage to the workpiece during ejection, making it inconvenient to use.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This is the first embodiment of the present invention. This embodiment provides a workpiece shaping mold for quick demolding, including a housing 1, a base plate 7 is provided inside the housing 1, a lower module 2 is provided on the upper surface of the base plate 7, an upper module 3 is provided at the top of the inner cavity of the housing 1, two guide blocks 4 are fixedly installed on the lower surface of the upper module 3, a molding component 5 is provided inside the lower module 2, and an ejection component 6 is provided inside the lower module 2.

[0032] The molding assembly 5 includes two transverse blocks 501 slidably disposed on the upper surface of the lower module 2. A compression spring 502 is fixedly connected to the outer surface of the transverse block 501. A mounting base 503 is fixedly installed on the upper surface of the transverse block 501. Several pressing modules 504 are inserted into the mounting base 503. Rotating plates 506 are hinged to both sides of the pressing module 504. A locking block 505 is fixedly connected to the side of the rotating plate 506 away from the pressing module 504. Two abutment blocks 508 are slidably disposed inside the pressing module 504. A compression spring 507 is fixedly connected between one end of the abutment block 508 and the pressing module 504.

[0033] Specifically, the lower surface of the pressure module 504 is provided with a limiting protrusion, and the interior of the mounting base 503 is provided with a through groove that cooperates with the pressure module 504. The inner wall of the through groove is provided with a stepped groove that cooperates with the limiting protrusion on the side near the transverse block 501. The inner wall of the through groove is provided with a locking groove that cooperates with the locking block 505. By setting the limiting protrusion, the pressure module 504 is prevented from dislodging from the through groove inside the mounting base 503, and the pressure module 504 remains stable under the abutment of the transverse block 501.

[0034] Specifically, the outer surfaces of the guide block 4 and the transverse block 501 are provided with mutually cooperating inclined surfaces. The compression spring 502 is fixedly installed between the transverse block 501 and the fixed block 604. Through the setting of the inclined surfaces, the guide block 4 can drive the transverse block 501 to retract inward as the upper module 3 moves downward.

[0035] Specifically, rectangular slots are provided on both sides of the pressure module 504. The rotating plate 506 is hinged to the inner wall of the rectangular slot. A torsion spring is provided at the hinge position of the rotating plate 506. A limiting groove is provided on the inner wall of the rectangular slot. A limiting protrusion that cooperates with the limiting groove is provided on the outer surface of the abutment block 508. The outer surfaces of the abutment block 508 and the locking block 505 are both provided with inclined surfaces. A protrusion is provided on the side of the rotating plate 506 near the abutment block 508. The rectangular slots are used to accommodate the rotating plate 506 and the abutment block 508. The limiting protrusions ensure that the abutment block 508 slides stably.

[0036] Furthermore, by pressing the abutment block 508, the abutment block 508 is driven into the rectangular grooves on both sides of the pressure module 504. Then, the rotating plate 506 is moved, which drives the locking block 505 to retract, thereby unlocking the pressure module 504. The pressure module 504 can then be pulled out from the mounting base 503 for replacement, facilitating mold replacement.

[0037] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 This is the second embodiment of the present invention. Based on the previous embodiment, the ejector assembly 6 includes a top plate 601 disposed between the lower module 2 and the base plate 7. A tension spring 602 is fixedly connected between the upper surface of the top plate 601 and the lower module 2. A fixing block 604 is fixedly connected inside the lower module 2. A plurality of ejector pins 603 are disposed on the upper surface of the top plate 601. A lifting plate 606 is slidably disposed inside the fixing block 604. L-shaped rotating rods 605 are hinged to both sides of the fixing block 604. A plurality of ejector rods 607 are disposed on the upper surface of the lifting plate 606.

[0038] Specifically, rectangular openings are provided on both sides of the fixed block 604, and the L-shaped rotating rod 605 is hinged at the rectangular opening. A torsion spring is provided at the hinge part of the L-shaped rotating rod 605. The upper surface of the short arm of the L-shaped rotating rod 605 abuts against the lower surface of the lifting plate 606. The rectangular openings facilitate the compression of the long arm of the L-shaped rotating rod 605 when the transverse block 501 retracts, thereby causing the short arm to drive the lifting plate 606 to rise through the rotation of the L-shaped rotating rod 605.

[0039] Specifically, the lifting plate 606 and the fixing block 604 are both provided with through holes that cooperate with the ejector pin 603. The ejector pin 603 passes through the through holes to eject the workpiece between the two pressing modules 504.

[0040] Specifically, the ejector rod 607 is arranged around the ejector pin 603. The outer surface of the ejector pin 603 has a groove that mates with the ejector rod 607. By arranging the ejector rod 607 around the ejector pin 603, the ejector rod 607 can be pre-ejected from the outer periphery of the workpiece. After the upper module 3 and the lower module 2 are engaged, the top of the ejector rod 607 is higher than the top of the ejector pin 603.

[0041] Furthermore, the upper module 3 moves upward, causing the two transverse blocks 501 to extend outward. Under the setting of the torsion spring at the hinge of the L-shaped rotating rod 605, rotation is achieved. Thus, through the short arm of the L-shaped rotating rod 605, the lifting plate 606 is driven to rise, thereby driving the ejector rod 607 to pre-eject the outer periphery of the workpiece, reducing the adhesion pressure between the outer periphery of the workpiece and the top of the mounting block.

[0042] Working Principle: During shaping, the upper module 3 is moved downwards by a cylinder and other tools, causing the guide block 4 to abut against the transverse block 501. The inclined surface causes the two transverse blocks 501 to retract, thus causing the pressure modules 504 on both sides to press the outer surface of the workpiece, achieving shaping. After the lower module 2 moves downwards, the top of the ejector pin 603 is pressed down, causing the top plate 601 to move downwards. The two transverse blocks 501 retract, abutting against the long arm of the L-shaped rotating rod 605. The rotation of the L-shaped rotating rod 605 causes the lifting plate 606 to descend, thus causing the ejector rod 607 to descend. After shaping, the upper module 3 moves upwards, causing the two transverse blocks 501 to expand outwards. Under the torsion spring at the hinge of the L-shaped rotating rod 605, they rotate, causing the lifting plate 606 to rise via the short arm of the L-shaped rotating rod 605, thus driving the... The ejector rod 607 pre-ejects the outer periphery of the workpiece to reduce the adhesion pressure between the outer periphery of the workpiece and the top of the mounting block. The upper module 3 continues to move upward, and under the reset action of the tension spring 602, it drives the top plate 601 to rise, thereby driving the ejector pin 603 to finally eject the workpiece. For different types of workpieces, the mounting base 503 can be removed from the outer surface of the transverse block 501, and the abutment block 508 can be pressed, thereby driving the abutment block 508 to retract into the rectangular grooves on both sides of the pressure module 504. Then, the rotating plate 506 is turned, thereby driving the protrusion at one end of the rotating plate 506 to engage with the inclined surface of the outer surface of the abutment block 508. Then, the rotating plate 506 is turned again to drive the locking block 505 to retract, thereby unlocking the pressure module 504. The pressure module 504 can then be pulled out from the mounting base 503 for replacement, facilitating mold replacement and finally completing the workpiece shaping operation.
