Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and in particular to a general-purpose plastic mold that is easy to demold. Background Technology

[0002] In the plastic parts processing process, plastic molds are widely used to process plastic parts. A plastic mold is a type of combined mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. The coordinated changes of the mold punch, die, and auxiliary molding system can produce a series of plastic parts of different shapes and sizes. Plastic molds are also used in the plastic parts processing.

[0003] In existing plastic molds, the injection mold uses a single cavity to fit the mold punch and mold cavity together. Then, liquid is injected between the mold punch and mold cavity to fix the mold punch and mold cavity, thus completing the processing of the plastic part.

[0004] However, existing plastic molds use a single cavity for injection molding. When processing other plastic parts, the entire mold needs to be replaced and reassembled, which is time-consuming, labor-intensive, and has poor performance. To address these issues, a universal plastic mold that is easy to demold is proposed. Utility Model Content

The rack 4 drives the U-shaped block 12 to move. The U-shaped block 12 drives the connecting plate 11 and the moving block 10 to rotate. The moving block 10 drives the two push plates 9 to move synchronously. The push plates 9 clamp the moving plate 8 around its perimeter. Then, the third cylinder 26 is activated to move the pressure plate 27 to fix the upper moving plate 8. After fixing, the second cylinder 14 is activated to insert the circular block 15 into the circular groove 16, which can prevent liquid leakage during plastic injection. To improve usability, when other plastic parts need to be injection molded, the movable limiting plate 21 moves the movable rod 22 and the stop block 23. The stop block 23 releases the limit on the push block 20, allowing for quick disassembly of the punch 19 and the die 18. Then, the punch 19 and die 18 that need to be replaced are put into the movable plate 8. The die 18 and punch 19 drive the push block 20 to press the stop block 23. The stop block 23 drives the support rod 24 to move and compress the spring 25. When the die 18 and punch 19 are fully inside the movable plate 8, the spring 25 rebounds, and the stop block 23 and the push block 20 engage, thereby fixing the die 18 and punch 19. This allows for quick installation and disassembly of the die 18 and punch 19, improving usability.
