1. the arrangement of the support ring, the support rod and the slot frees the hands of workers and brings convenience to the operation of the workers;

2. the arrangement of the slots enables the injection molding barrel to be adaptive to the molding boxes with different sizes, so that the flexibility of the injection molding machine in use is improved;

3. the height groove is arranged, so that a worker can quickly and accurately adjust the height of the injection molding barrel, and the probability of deflection of the support ring and the injection molding barrel is reduced;

4. the rubber sleeve is arranged, so that the supporting rod can be inserted on the rack more stably, and the stability of the injection molding barrel in the injection molding process is improved;

5. the arrangement of the check ring ensures that the stability of the injection molding cylinder in the injection molding process is better;

6. the setting of strengthening rib prolongs the life of support ring and bracing piece, improves the stability of a section of thick bamboo of moulding plastics at the in-process of moulding plastics.
