[0004] Although the injection mold can be clamped, there are still some problems in daily use. The current design requires the clamping operation to be performed in steps, that is, first completing the clamping of the left and right sides, and then adjusting the front and rear clamping. This series of actions undoubtedly increases the complexity of the process, prolongs the non-productive time, and reduces the overall operation efficiency. Utility Model Content
