[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes an injection vulcanizing machine which is convenient for replacing injection heads. When installing the injection heads, the motor drives the rotating plate to rotate so that the injection heads reach the set position. The semicircular block is clamped on the injection heads by rotating the rotating block. Then the rotating block rotates and the electric telescopic rod retracts to drive the injection heads to rise. The rise drives the limit block to move upward and applies force to the clamping block to tighten the first spring. When the limit block reaches the appropriate position, the clamping block is released and quickly bounces back to its original position under the restoring force of the first spring. At this time, the lower end of the limit block is at the upper end of the clamping block, thereby realizing the fixing operation of the injection heads and automatic operation, which improves the work efficiency and reduces the work intensity of the workers.

[0023] 2. The utility model provides an injection vulcanizing machine for convenient replacement of injection heads. When executing the injection head replacement procedure, the motor rotates the rotating plate to allow the replaced injection head to reach the set position, and the semicircular block on the rotating block is clamped on the first and second injection heads, so that the electric telescopic rod retracts and drives the first injection head and the second injection head to rise. As the first injection head rises, the protrusion on its outside also moves upward, and applies an upward thrust to the clamping block inside the mounting block, so that the clamping block and the first spring are compressed. When the protrusion reaches the highest point, the top of the protrusion is embedded in the groove under the limit block. Next, the electric telescopic rod is extended, and the rotating block is lowered, so that the first injection head slides inside the mounting block. As the first injection head and the second injection head continue to move relative to each other, the first magnetic block and the second magnetic block that were originally attracted to each other are gradually separated, and the protrusion presses the clamping block, so that the clamping block shrinks and passes through the outside of the limit block, thereby realizing the separation of the first injection head from the mounting block. Finally, the motor drives the rotating block to rotate again, so that the position exchange of the first injection head and the second injection head can be successfully completed, and a fully automated injection head replacement operation is achieved, thereby improving production efficiency.
