Description

Technical Field

[0001] This invention relates to the field of demolding tooling technology, and in particular to an easy-to-use demolding tooling. Background Technology

[0002] Easy-to-use demolding fixtures are tools specifically designed to help workers quickly and easily remove molded workpieces from molds. Their main purpose is to improve demolding efficiency, reduce manpower input, avoid damage to workpieces and molds, ensure workpiece quality is not affected, and reduce potential risks and losses during production. Easy-to-use demolding fixtures are widely used in plastic molding, metal casting, rubber processing, and other fields, and are particularly important in mass production. They are also commonly seen in daily life.

[0003] Existing technologies, such as the invention with publication number CNB, disclose a top connecting plate demolding fixture. This patent employs a fixed frame, at least one demolding structure, a handle, and a limiting clip. The demolding structure includes an elastic component, a shaft, and a pull claw. One end of the elastic component is fixed to the fixed frame, and the other end is fixed to the pull claw. The shaft is fixed to the pull claw. The limiting clip is fixed to the fixed frame, and the extension direction of the fixed frame is the same as the direction of the shaft and parallel to the main body of the shaft. When the demolding structure is not under force, its natural extension length is greater than that of the limiting clip. By adding a demolding fixture, such products no longer require manual demolding of individual cavities. Instead, all products can be simultaneously demolded from the rubber mold using a single mold, greatly improving production efficiency and reducing manufacturing costs.

[0004] In daily use, it has been found that during the processing and production of injection molds, it is necessary to separate the upper mold base from the lower mold base after injection molding. However, the demolding operation usually requires the operator to perform the demolding manually, which will result in problems such as time and effort wasted for the operator, and the demolding tool flying off and causing personnel to be bumped or injured.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0019] 1. In this invention, by setting a demolding mechanism, the position of the support plate can be raised and lowered. The first and second scissor frames between the sliding frame and the base are used in combination to lift the top plate, which is adjustable and movable on the upper surface of the support rod, and the upper and lower mold bases. During this process, the bolts between the upper and lower mold bases can be ejected effectively and conveniently by using the combination of the adjusting frame, the rotating frame and the ejector rod, thereby effectively and conveniently demolding the entire upper and lower mold bases.

[0020] 2. In this invention, by setting a telescopic mechanism, the mechanical energy of the push rod in the entire demolding fixture can be retracted. By retracting the push rod into the inlay groove opened on the surface of the mounting plate, the position of the push rod can be slidably adjusted by the slide rail fixed in the inlay groove, which can effectively expand the operating space when operating the entire demolding fixture.

[0021] 3. In this invention, by setting a counterweight mechanism, the mass of the bottom end of the mounting plate can be increased, which helps to further stabilize and limit the position of the mounting plate when operating the demolding fixture set at the top of the mounting plate, and avoids the situation of overturning when the demolding fixture is adjusted. At this time, the counterweight block is used to increase stability and facilitate better load-bearing and fixing.

[0022] 4. In this invention, by setting up an installation mechanism, a solid foundation is provided by the close contact between the fixed frame and the mounting plate, ensuring the stability and support of the entire device. The connection method between the connecting plate and the connecting column and connecting shaft ensures reliable fixation between the various components and can effectively transmit and resist external forces. The combination of the design of the rotating rod, the clamping frame and the inlay frame allows the device to perform necessary rotational adjustment operations. At the same time, the design of the rotating rod allows the device to rotate flexibly when needed, which helps to better replace the limit support operation of the support rod.

[0034] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0036] like Figures 1 to 5As shown, this invention provides an easy-to-use demolding fixture, including a mounting plate 1, an upper mold base 5, a lower mold base 4, and a mounting mechanism 10. When operating the demolding fixture, the entire fixture is first supported and positioned using the mounting plate 1, and moved using pulleys 3 on the lower surface of the mounting plate 1. A push rod 2 on one side of the mounting plate 1 is used for auxiliary operation. Then, a telescopic mechanism 7 on the mounting plate 1 corresponding to the push rod 2 is used to retract the push rod 2. Next, to stabilize the position of the entire demolding fixture, a counterweight mechanism 8 on the lower surface of the mounting plate 1 is used to increase its mass, preventing the mounting plate 1 from causing the demolding fixture to wobble or shift. Finally, the mounting plate 1... The demolding mechanism 6 on the upper surface is used for adjustment. The sliding frame 619 on the lower surface of the support plate 9 is matched with the base 621. By rotating the positions of the first scissor bracket 622 and the second scissor bracket 623, the position of the entire support plate 9 is raised and lowered. Then, the rotating shaft 603 on the surface of the two side support rods 601 is rotated, which drives the top plate 604 to insert into the connecting groove 606 between the upper mold base 5 and the lower mold base 4, so that the upper mold base 5 and the lower mold base 4 can be separated. During this process, the rotating frame 614 in the adjusting frame 612 drives the ejector rod 616 to eject the bolts set between the upper mold base 5 and the lower mold base 4, so as to facilitate and quickly demold the upper mold base 5 and the lower mold base 4.

[0037] The following section will explain the specific setup and function of its demolding mechanism 6, telescopic mechanism 7, counterweight mechanism 8, and installation mechanism 10.

[0038] like Figure 3 , Figure 4 and Figure 5As shown, the surfaces of the mounting plate 1 and the bearing plate 9 are provided with a demolding mechanism 6. The demolding mechanism 6 includes two support rods 601 and several bolts and nuts 611. The bottom ends of the two support rods 601 are fixedly connected to the surface of the mounting plate 1 via the mounting mechanism 10. The two support rods 601 are located on both sides of the mounting plate 1, and the support rods 601 are used to support, fix and limit the demolding parts. The upper end of the support rods 601 is fixedly connected to a support plate 605, which limits the movement of the top plate 604. The cross-section of the support plate 605 is "L" shaped. A positioning block 602 is fixedly connected to the surface of the support plate 605. The positioning block 602 can provide auxiliary support for the rotating shaft 603. The inner wall of the positioning block 602 is threaded through the rotating shaft 603. Shaft 603 can drive top plate 604 to move in position. One end of shaft 603 is rotatably connected to top plate 604. Top plate 604 can insert and eject upper mold base 5 and lower mold base 4. The cross-section of top plate 604 is wedge-shaped. The surface of top plate 604 slides through the short arm end surface of support plate 605. Several connecting grooves 606 are opened on the surface of lower mold base 4 near upper mold base 5. The connecting grooves 606 facilitate insertion and compression with top plate 604. The cross-sectional dimensions of connecting grooves 606 are adapted to the cross-sectional dimensions of top plate 604. Upper mold base 5 and lower mold base 4 are fixedly connected by bolts and nuts 611. Several stops 607 are evenly fixedly connected on the surface of bearing plate 9 corresponding to the position of lower mold base 4. The stops 607 facilitate the positioning of fixed block 608. The guide and protection are provided. The cross-section of the stop 607 is triangular. An adjusting rod 609 is threaded through the surface of the bearing plate 9 corresponding to the position of the stop 607. The adjusting rod 609 can press the position of the fixed block 608. The surface of the lower mold base 4 abuts against the fixed block 608 corresponding to the position of the stop 607. The fixed block 608 facilitates abutment and fixation of the surface of the lower mold base 4. An adjusting hole 610 is opened on the surface of the fixed block 608. The adjusting hole 610 facilitates the movement of the fixed block 608. The inner wall of the adjusting hole 610 slides through the arc surface of the adjusting rod 609. A base 621 is fixedly connected to the surface of the mounting plate 1. The base 621 is located on the side where the two support rods 601 are close to each other. A sliding frame 6 is fixedly connected to the lower surface of the bearing plate 9. 19. A first scissor lift 622 and a second scissor lift 623 are installed on the side of the sliding frame 619 and the base 621 that are close to each other. The first scissor lift 622 and the second scissor lift 623 can raise and lower the position of the entire support plate 9. The first scissor lift 622 and the second scissor lift 623 are rotatably connected. The bottom end of the first scissor lift 622 is slidably connected to the inner wall of the base 621, and the top end of the first scissor lift 622 is rotatably connected to the inner wall of the sliding frame 619. The bottom end of the second scissor lift 623 is rotatably connected to the inner wall of the base 621, and the top end of the second scissor lift 623 is slidably connected to the inner wall of the sliding frame 619. A drive shaft 620 is rotatably connected to one side surface of the sliding frame 619. The drive shaft 620 can drive the movement of the second scissor lift 623.The arc surface of the drive shaft 620 is threaded through the upper end of the second scissor lift 623. An adjusting bracket 612 is inserted into the side surface of the upper die holder 5 and the lower die holder 4 that are close to each other. The adjusting bracket 612 can be inserted and fixed to the position of the lower die holder 4 and the upper die holder 5 that are close to each other. The upper end cross section of the adjusting bracket 612 is U-shaped. The position of the adjusting bracket 612 corresponds to the position of the bolt and nut 611. Both sides of the upper end of the adjusting bracket 612 are threaded through with a pressing rod 617. The pressing rod 617 can press and limit the position of the adjusting bracket 612 to prevent the adjusting bracket 612 from falling off. A positioning bracket 61 is fixedly connected to the lower surface of the adjusting bracket 612. 3. A push rod 616 slides through the inner wall of the positioning frame 613, allowing the bolt to be ejected. The bottom end of the push rod 616 is rotatably connected to the same rotating frame 614 on the surface of the positioning frame 613. The rotating frame 614 facilitates the pressing and moving of the push rod 616. A protective sleeve 615 is fixedly connected to the surface of the rotating frame 614. A pressing pad 618 is fixedly connected to the bottom end of the pressing rod 617, and the surface of the pressing pad 618 abuts against the side wall of the upper mold base 5. The push rod 616 is made of hard alloy, ensuring long-term use and preventing deformation. The cross-sectional dimensions of the push rod 616 are compatible with the cross-sectional dimensions of the bolt and nut 611.

[0039] During the demolding process of the processed parts, first rotate the drive shaft 620 on one side of the sliding frame 619 on the lower surface of the bearing plate 9, so that the drive shaft 620 drives the lifting and lowering adjustment of the second scissor lift 623 and the first scissor lift 622 until they move to the position corresponding to the top plate 604 at the upper end of the support rod 601. Then, remove the bolts and nuts 611 between the lower mold base 4 and the upper mold base 5 on the upper surface of the bearing plate 9. During this process, in order to facilitate the ejection of the bolts, the adjusting bracket 612 and... The upper mold base 5 and the lower mold base 4 are inserted and fixed. Then, the rotating frame 614 on the surface of the adjusting frame 612 is rotated, so that the bolt is ejected by the ejector rod 616 sliding on the surface of the adjusting frame 612 with the help of the positioning frame 613. At this time, the rotating shaft 603 on the surface of the support rod 601 is rotated, so that the rotating shaft 603 drives the top plate 604 to move in position, so that the top plate 604 is inserted into the connecting groove 606 on the surface of the lower mold base 4 and ejected, which facilitates the demolding operation between the upper mold base 5 and the lower mold base 4.

[0040] like Figure 6 , Figure 7 and Figure 8As shown, a telescopic mechanism 7 is provided on one side surface of the mounting plate 1 corresponding to the position of the push rod 2. The telescopic mechanism 7 includes two inlay slots 701, which can retract the push rod 2. The two inlay slots 701 are formed on both sides of the mounting plate 1. The length of the inlay slots 701 is adapted to the length of the push rod 2. A slide rail 702 is fixedly connected to the lower surface of the inner wall of the inlay slot 701. The slide rail 702 can slide and limit the position of the push rod 2 when it retracts. The cross-section of the slide rail 702 is "L" shaped. A sliding shaft 708 is movably connected to the inner wall of the slide rail 702. The sliding shaft 708 can drive the push rod 2 to slide. The push rod 2 has grooves 709 on its lower surfaces at both ends. The grooves 709 can limit the movement of the push rod 2. The inner wall of the grooves 709 is slidably connected to one end of the sliding shaft 708. A through column 703 is fixedly connected to the lower surface of the inner wall of the inlay groove 701. A movable column 704 slides through the inner wall of the through column 703. The movable column 704 can be stretched and limited by the extrusion force generated by the spring 705. A support pad 706 is fixedly connected to the upper end of the movable column 704. A spring 705 is sleeved on the arc surface of the movable column 704. The two ends of the spring 705 are fixedly connected to the through column 703 and the support pad 706, respectively. The lower surface of the push rod 2 has an insertion hole 707, which can be inserted and fixed with the moving column 704 to prevent the push rod 2 from shaking or shifting. The inner wall of the insertion hole 707 abuts against the surface of the support pad 706. Two limiting rods 710 are fixedly connected to one end surface of the mounting plate 1 corresponding to the push rod 2. The limiting rods 710 move the limiting plate 711 by means of the torsional force generated by the torsion spring, so as to facilitate engagement and limitation with the limiting groove 714 opened on the arc surface of the push rod 2. The arc surface of the limiting rod 710 is rotatably connected to the limiting plate 711. The arc surface of the limiting rod 710 is fitted with a first coil spring 712. The two ends of the coil spring 712 are fixedly connected to the limiting rod 710 and the limiting plate 711, respectively. The arc surface of the push rod 2 is provided with a limiting groove 714 corresponding to the position of the limiting plate 711. The limiting groove 714 can be effectively inserted into the limiting plate 711. The cross section of the limiting groove 714 is inclined. The surface of the limiting plate 711 is fixedly connected to the limiting post 713. The limiting post 713 and the arc-shaped limiting groove 714 can prevent the position from falling off. The surface of the limiting post 713 is engaged with the inner wall of the limiting groove 714. The cross section of the limiting plate 711 on the side that is close to each other is arc-shaped. One side of the limiting plate 711 abuts against the arc surface of the push rod 2.

[0041] After moving the entire demolding fixture to the designated position, the position of the push rod 2 will be adjusted to facilitate the retraction operation of the push rod 2 and expand the demolding operation space. Pull the limiting plate 711 on one side of the surface of the mounting plate 1 to separate the limiting post 713 on one end of the limiting plate 711 from the limiting groove 714 on the surface of the push rod 2. Then, pull the moving post 704 in the insert groove 701 to separate the moving post 704 from the insertion hole 707 at the bottom of the push rod 2. Then pull the push rod 2 to slide along the slide rail 702 in the insert groove 701 with the help of the sliding shaft 708. At this time, the entire push rod 2 will be effectively retracted into the insert groove 701 on the side wall of the mounting plate 1.

[0042] like Figure 9 and Figure 10 As shown, a counterweight mechanism 8 is provided on the inner wall of the lower surface of the mounting plate 1. The counterweight mechanism 8 includes two mounting frames 81. The mounting frames 81 facilitate the docking and fixing of the counterweight block 82. One side of the two mounting frames 81 is fixedly connected to the inner wall surface of the mounting plate 1. The two mounting frames 81 are located on both sides of the inner wall of the mounting plate 1. Several auxiliary holes 83 are opened on the surface of the mounting frames 81. The auxiliary holes 83 can drive the inlay frame 87 to move in position with the help of the auxiliary rod 84. The auxiliary rod 84 is slidably connected to the inner wall of the auxiliary hole 83. The auxiliary rod 84 can slide in position. The upper end of the auxiliary rod 84 is fixedly connected to the inlay frame 87. The same counterweight block 82 is inserted into the inner wall of the two inlay frames 87. The counterweight block 82 can effectively increase the mass and facilitate the weight increase and stabilization of the entire demolding fixture. The arc surface of the auxiliary rod 84 is fitted with a protective ring 85. The protective ring 85 can prevent the auxiliary shaft 86 from loosening and falling off. The lower surface of the protective ring 85 abuts against the upper surface of the auxiliary shaft 86.

[0043] During the operation of the demolding fixture set on the upper part of the entire mounting plate 1, the mass of the bottom of the mounting plate 1 can be increased by using the counterweight 82. First, the inlay frames 87 on both sides of the lower surface of the mounting plate 1 are slid along the auxiliary hole 83 with the help of the auxiliary rod 84. Then, the counterweight 82 is placed in the two inlay frames 87. Then, the two inlay frames 87 are stretched, and at the same time, the auxiliary shaft 86 of the arc surface of the auxiliary rod 84 is rotated to squeeze and fix the position of the inlay frames 87, thereby effectively and conveniently making the entire demolding fixture more stable during use.

[0044] like Figure 2As shown, the mounting mechanism 10 is positioned on both sides of the surface of the mounting plate 1, corresponding to the support rods 601. The mounting mechanism 10 includes a fixed frame 1001, the lower surface of which abuts against the surface of the mounting plate 1. Connecting plates 1003 are fixedly connected to both sides of the fixed frame 1001. The inner wall of the connecting plate 1003 has a U-shaped cross-section. The U-shaped groove limits the fixed frame 1001 to ensure no lateral displacement relative to the mounting plate 1, thus avoiding positional deviation of the support rods 601. The U-shaped locking frame 1009 at the bottom of the support rod 601 can be directly engaged with the rotating rod 1007 on the mounting bracket 1006 without the need for manual intervention. Equipped with aligned bolt holes, it significantly shortens operation time, making it especially suitable for scenarios requiring frequent tooling changes. A connecting post 1004 is inserted into the inner wall of the connecting plate 1003. The bottom end of the connecting post 1004 is fixedly connected to the surface of the mounting plate 1. A connecting shaft 1005 is threaded onto the arc surface of the connecting post 1004. The lower surface of the connecting shaft 1005 abuts against the surface of the connecting plate 1003. Mounting brackets 1006 are fixedly connected to both sides of the fixing frame 1001. A rotating rod 1007 is rotatably connected to the inner wall of the mounting bracket 1006. A mating frame 1002 is fixedly connected to the bottom surface of the support rod 601. Both sides of the mounting frame 1002 are fixedly connected to a retaining frame 1009. The inner wall of the retaining frame 1009 has a U-shaped cross-section. The inner wall of the retaining frame 1009 engages with the arc surface of the rotating rod 1007. The arc surface of the rotating rod 1007 is threadedly connected to a mounting shaft 1012. The mounting shaft 1012 is threadedly tightened onto the rotating rod 1007, directly pressing against the side wall of the mounting bracket 1006 to form a rigid lock and bear the main working load of the support rod 601. Both ends of the inner wall of the mounting bracket 1006 are fitted with second coil springs 1008. The two ends of the second coil springs 1008 are respectively connected to the mounting bracket 1006 and the rotating rod 1007. 07 Fixed connection: The rotating rod 1007 automatically rotates to the locking position under the torque of the spring 705, ensuring that the locking frame 1009 and the rotating rod 1007 fit tightly together, avoiding oversights caused by manual locking. The arc surface of the rotating rod 1007 is movably connected to the inlay frame 1011. The cross-section of the inlay frame 1011 is "L" shaped. The surface of the locking frame 1009 has an inlay hole 1010. The inner wall of the inlay hole 1010 is inserted into one end surface of the inlay frame 1011. The inlay frame 1011 is inserted into the inlay hole 1010 on the side wall of the locking frame 1009, forming a physical limit and preventing the rotating rod 1007 from rotating accidentally. Even if the mounting shaft 1012 loosens due to vibration, the inlay frame 1011 can still prevent the rotating rod 1007 from coming off, significantly improving equipment safety.

[0045] After prolonged use of the support rod 601, to facilitate replacement of the limit position, the mounting mechanism 10 between the mounting plate 1 and the support rod 601 can be used for auxiliary operation. First, the support rod 601 is inserted and fixed to the fixing frame 1001 on the surface of the mounting plate 1 via the bottom-fixed docking frame 1002. At the same time, the connecting plates 1003 at both ends of the fixing frame 1001 are inserted into the connecting posts 1004 on the surface of the mounting plate 1. Then, the connecting shaft 10 on the arc surface of the connecting post 1004 is rotated. 05. At this point, the position of the entire fixed frame 1001 will be fixed. Then, flip the rotating rod 1007 inside the mounting bracket 1006 so that the upper arc surface of the rotating rod 1007 is engaged with the inner wall of the clip frame 1009 fixed to the side wall of the docking frame 1002. At the same time, pull the inlay bracket 1011 on the arc surface of the rotating rod 1007 so that one end of the inlay bracket 1011 is inserted and fixed with the inlay hole 1010 opened on the surface of the clip frame 1009. Finally, the mounting shaft 1012 on the arc surface of the rotating rod 1007 is screwed and pressed to fix it.
