[0026] Please refer to Figures 1 to 4 , the present utility model provides a technical solution:

[0027] An ejection structure for mold processing that is convenient for disassembly and assembly, including a concave mold body 1. A push plate 2 is slidably installed at the center of the bottom of the concave mold body 1. It also includes an ejection assembly. The ejection assembly includes a push head 6. The push head 6 is slidably installed at the bottom of the connecting seat 4. The push head 6 is fixedly connected to the telescopic end of a cylinder 7. The cylinder 7 is fixedly installed at the bottom of the processing table 8. By setting the cylinder 7 to provide power for the push head 6, the push head 6 can push the alignment plate 13 and the push plate 2 to eject the workpiece from the concave mold body 1, thus completing the demolding. A bottom of the push plate 2 is fixedly installed with an alignment plate 13. A connection groove 14 is opened at the bottom of the alignment plate 13. The connection groove 14 is slidably matched with the push head 6. By setting the alignment plate 13 and the connection groove 14, the connection stability between the push plate 2 and the push head 6 can be improved.

[0028] Four groups of sliding plates 15 are fixedly installed around the bottom of the alignment plate 13. The sliding plates 15 are slidably installed in installation grooves 16 opened at the bottom of the concave mold body 1. The sliding plates 15 are slidably matched with slide bars 17 fixedly installed in the installation grooves 16. A compression spring 18 is slidably sleeved on the surface of the slide bar 17. The bottom of the compression spring 18 abuts against the top surface of the sliding plate 15. The top of the compression spring 18 is fixedly connected to the top of the installation groove 16. By setting the compression spring 18, a downward force can be applied to the sliding plate 15. After the demolding is completed, the sliding plate 15 can be automatically pushed to move downward. Driven by the four groups of sliding plates 15, the push plate 2 and the alignment plate 13 can return to their original positions, facilitating the next processing.

[0029] It also includes a connection assembly. The connection assembly includes a connection seat 4. The connection seat 4 is fixedly installed in the middle of the top surface of the processing table 8. Two groups of support frames 19 are fixedly installed on both sides of the bottom of the processing table 8. The connection seat 4 has a sliding clearance fit with the concave mold body 1. Card slots 5 are opened on both sides of the connection seat 4. Two groups of clamping blocks 3 are fixedly installed on the outer walls of both sides of the concave mold body 1. The card slots 5 and the clamping blocks 3 are mutually clamped. By setting the connection assembly, the concave mold body 1 and the ejection assembly can be quickly installed, facilitating quick demolding, improving the processing efficiency. At the same time, it is also convenient for the operator to replace the concave mold body 1 with different inner cavity shapes, facilitating the processing of different workpieces, improving the application range of this device. And when batch processing with materials that solidify and form slowly, a set of connection assembly and ejection assembly can be set to cooperate with multiple groups of concave mold bodies 1 to use, thereby improving the processing efficiency and reducing the cost at the same time. Two groups of fixed pin rods 9 are slidably installed on both sides of the connection seat 4. The two groups of fixed pin rods 9 are respectively fixedly connected to both ends of a pull rod 10. A tension spring 11 is slidably sleeved on the surface of the fixed pin rod 9. One end of the tension spring 11 is fixedly connected to the connection seat 4, and the other end of the tension spring 11 is fixedly connected to the pull rod 10. The clamping block 3 is provided with a positioning hole 12. The positioning hole 12 is slidably matched with a positioning pin. By setting the fixed pin rod 9, the connection stability between the concave mold body 1 and the connection assembly can be improved, thus ensuring that the ejection assembly can work normally.

[0030] During specific use, move this device to the designated position and fix this device through the mounting holes at the bottom of the support frame 19. After the workpiece is completely cooled and hardened, move the concave die body 1, align the clamping block 3 with the clamping groove 5, pull the pull rod 10, pull out the fixed pin rod 9 outward, then place the concave die body 1 in the connecting seat 4. At the same time, the clamping block 3 is snapped into the clamping groove 5. Release the pull rod 10, and the tension spring 11 pulls the fixed pin rod 9 to automatically reset. At the same time, the fixed pin rod 9 is snapped into the positioning hole 12 to fix the concave die body 1 in the connecting seat 4. Start the cylinder 7, the telescopic end of the cylinder 7 pushes the push head 6, and the push head 6 pushes the alignment ring closing push plate 2, so that the push plate 2 pushes the workpiece upward to eject it from the concave die body 1, thus realizing demoulding.
