Description

Technical Field

[0001] This utility model relates to the field of mold demolding technology, and in particular to a rapid demolding device for resin crafts of multiple specifications. Background Technology

[0002] In the resin crafts manufacturing industry, products often exhibit diverse designs and significant size variations, placing high demands on the flexibility and efficiency of the demolding process. As a crucial piece of equipment connecting the mold and the finished product, the ease of assembly and disassembly of the demolding device, and its adaptability to various mold sizes, directly impacts production efficiency and the integrity of the finished product's appearance. Therefore, developing a device that can adapt to multiple mold sizes and achieve rapid and precise demolding has become a key direction for solving the demolding challenges in the mass production of resin crafts. Existing resin craft demolding devices mostly adopt a fixed structure design. The mold mounting platform is an integrated rigid frame, and the demolding action is mainly achieved by the cylinder or hydraulic rod driving the ejection component. The mold is usually fixed by multiple sets of bolts passing through the mold flange and the preset holes in the worktable. When adjusting the mold installation space, it is necessary to replace the liner of different sizes or replace the entire worktable. The assembly and disassembly of the demolding components require the use of tools such as wrenches and screwdrivers to remove the connecting bolts one by one before the components can be replaced or maintained. In the existing technology, the disassembly and assembly process of demolding components is cumbersome and time-consuming. Operators need to adjust the tool alignment bolts multiple times, which not only prolongs the mold replacement cycle, but also easily leads to misalignment of the ejector component with the mold cavity during demolding due to uneven bolt tightening force and component alignment deviation. This can result in demolding jamming, and even damage to the edges and scratches on the surface of the finished product, seriously affecting the finished product qualification rate and making it difficult to meet the production needs of rapid changeover of multi-specification molds. Summary of the Invention

[0003] To overcome the above shortcomings, this utility model provides a multi-specification rapid demolding device for resin crafts, which aims to improve the problem that the fixed workbench space of traditional equipment cannot be adapted to multi-specification molds and the ejection device is fixed and cannot be disassembled.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a multi-specification rapid demolding device for resin crafts, including a worktable, an adjustment component provided on the inner wall of the worktable, sliding columns provided on all four sides of the top of the worktable, a top plate provided on the outer wall of the sliding columns, a quick-release component provided on the inner wall of the top plate, and a driving component provided on the side wall of the worktable.

[0006] As a further description of the above technical solution: The other ends of the baffle one and the baffle two are threadedly connected to a lead screw, and the top end of the lead screw is fixedly connected to a knob. The sliding rod and the outer wall of the lead screw are slidably connected to the inner wall of the groove.

[0007] As a further description of the above technical solution: The drive assembly includes a controller, one side of which is fixedly connected to one side of the workbench. A bracket is fixedly connected to the bottom of the workbench, and an electrical box is fixedly connected to the outer wall of the bracket.

[0008] As a further description of the above technical solution: The top plate is provided with a frame, and electric push rods are provided on both the left and right sides of the frame. The output end of the electric push rod is fixedly connected to the top plate, and multiple sliding columns are slidably connected to the top plate and the frame around its perimeter.

A material box is installed at the bottom of the workbench.

[0010] As a further description of the above technical solution: The bottom of the workbench is provided with multiple support legs, and the top of each support leg is fixedly connected to the bottom of the workbench.

[0011] This utility model has the following beneficial effects: 1. In this utility model, firstly, align the positioning rod with the slot at the top of the top rod, press down on the second knob to compress and contract the spring, then rotate the second knob to let the positioning rod engage with the slot inside the housing. When disassembling, rotate the second knob in the opposite direction to release the positioning rod. This solves the problems of cumbersome disassembly and assembly, long time consumption, and poor component fit due to operation errors in traditional structures.

The quick-release assembly includes an ejector pin 13, which acts as the demolding actuator, directly contacting the resin craft. It pushes the product out of the mold by applying downward force. The outer wall of the ejector pin 13 is slidably connected to the inner wall of the top plate 11. A slot 18 is provided on the inner wall of the ejector pin 13. A buckle 17 is rotatably connected to the top of the ejector pin 13, and is rotatably connected to the inner wall of the slot 18. When the buckle 17 engages with the slot 18 of the ejector pin 13, the ejector pin 13 is fixed to the inner wall of the top plate 11. To replace the ejector pin 13, simply turn knob 12 to unlock it. A spring 16 is provided on the outer wall of the buckle 17, with one end of the spring 16 fixedly connected to… The top plate 11 is connected to a housing 15, the outer wall of which is fixedly connected to the inner wall of the top plate 11. The housing 15 is fixed inside the top plate 11 as a mounting carrier for the spring 16 and the buckle 17. The other end of the spring 16 is fixedly connected to a knob 12. When the knob 12 is turned, the spring 16 is compressed, which causes the buckle 17 to disengage from the slot 18. At this time, the top rod 13 can be pulled out directly to achieve quick disassembly. The bottom end of the top rod 13 is slidably connected to a silicone sleeve 14. The silicone sleeve 14 is made of flexible silicone material to prevent the hard metal top rod 13 from directly contacting the surface of the craft, avoiding scratches, indentations and other damage, and improving the product qualification rate.

[0017] Reference Figure 2 and Figure 5 The adjustment component includes a baffle 5, the outer wall of which is slidably connected to the inner wall of the worktable 1. Grooves 2 are provided around the worktable 1 to provide moving space for the sliding rod 7 and the lead screw 4. A baffle 6 is slidably connected to the inner wall of the baffle 5. The two can work together to form mold positioning areas of different sizes on the top of the worktable 1. A sliding rod 7 is fixedly connected to one end of the baffle 5 and the baffle 6 to provide moving action for the baffle 5 and the baffle 6. A lead screw 4 is threaded to the other end of the baffle 5 and the baffle 6. A knob 3 is fixedly connected to the top of the lead screw 4. The outer walls of the sliding rod 7 and the lead screw 4 are slidably connected to the inner wall of the groove 2. Rotating the knob 3 can drive the lead screw 4 to rotate, thereby pushing the baffle 5 and the baffle 6 to move along the groove 2. Tightening the knob 3 can accurately control the size of the internal space of the mold. The drive assembly includes a controller 19, the core of the device's control. One side of the controller 19 is fixedly connected to one side of the workbench 1.

Electric push rods 24 are installed on both sides of the frame 9, providing power for the downward pressure of the push rod 13. The output end of the electric push rod 24 is fixedly connected to the top plate 11, causing the top plate 11 to drive the push rod 13 to move along the sliding column 10. The top plate 11 and the frame 9 are connected around the perimeter. Multiple sliding pillars 10 are slidably connected to provide a moving path for demolding. Positioning rods 8 are fixedly installed on the left and right sides of the top of the worktable 1. The bottom of each positioning rod 8 is fixedly connected to the top of the worktable 1 to prevent the mold from shifting during the lifting and lowering of the top plate 11 and to ensure that the ejector rod 13 is accurately aligned with the center of the mold. A material box 22 is installed at the bottom of the worktable 1 to collect the material after demolding. Multiple support legs 23 are installed at the bottom of the worktable 1. The top of each support leg 23 is fixedly connected to the bottom of the worktable 1. The support legs 23 are evenly distributed at the bottom of the worktable 1 to ensure the stability of the worktable 1 and to avoid mold displacement or product damage due to vibration during demolding.

[0018] Working principle: When it is necessary to demold resin crafts, first adjust the internal space of the workbench 1 to fit the mold to be demolded. First, loosen the knobs 3 on both sides of the workbench 1 to drive the lead screw 4 to rotate on the inner wall of the baffle 5 and the baffle 6. Then, through the sliding rod 7 on one side of the baffle 5 and the baffle 6, slide along the grooves 2 on both sides of the workbench 1 to adjust the position. After the space size is adapted to the mold, tighten the knobs 3 to fix the baffle and complete the space adjustment of the workbench 1. The mold to be demolded is then aligned and fixed with the positioning rods 8 on both sides of the workbench 1. The electrical box 21 on the bracket 20 on one side of the workbench 1 provides power to the whole device. The power switch of the controller 19 is turned on, driving the electric push rod 24. The output end of the electric push rod 24 causes the top plate 11 under the frame 9 to slide down along the sliding column 10, which simultaneously drives the push rod 13 at the bottom of the top plate 11 to move down, realizing the mold ejection. The silicone sleeve 14 at the top of the push rod 13 can protect the material from breakage. Finally, the mold falls to the material box 22 at the bottom of the workbench 1.

[0019] If the top rod 13 needs to be replaced, the operator only needs to manually press down the knob 12 to compress the internal spring 16, and at the same time rotate the knob 12 to release the buckle 17 from the slot 18 inside the housing 15, thus quickly completing the replacement of the top rod 13.
