The O-shaped sealing ring is embedded in an annular groove formed in the core mold, and the diameter of the O-shaped sealing ring is larger than the depth of the annular groove.
The O-shaped sealing ring is made of silicon rubber.
The threaded sleeve is fixed on the shaft shoulder of the core mold through the O-shaped sealing ring.
The outer diameter of the O-shaped sealing ring is larger than the inner diameter of the internal thread of the thread insert.
When the screw sleeve is sleeved on a core mold and pushed into a position with an O-shaped sealing ring on the core mold, the O-shaped sealing ring is tightly attached to an internal thread of the screw sleeve due to contact pressure generated by elastic deformation of the O-shaped sealing ring, so that the sealing and fixing effects of the screw sleeve are achieved.
The O-shaped sealing ring is embedded in an annular groove formed in the core mold, and the diameter of the O-shaped sealing ring is larger than the depth of the annular groove.
The O-shaped sealing ring is made of silicon rubber.
The threaded sleeve is fixed on the shaft shoulder of the core mold through the O-shaped sealing ring.
The outer diameter of the O-shaped sealing ring is larger than the inner diameter of the internal thread of the thread insert.
The invention has the following beneficial effects and advantages:
1. compact structure, preparation convenience: the invention is optimally designed on the basis of the original core mould, and utilizes the self-made O-shaped sealing ring to be embedded into the groove while not influencing the structure, thereby achieving the purposes of compact structure, firm and stable sealing, simple and quick manufacture and effectively improving the production efficiency.
2. High temperature resistance, ageing resistance, oil resistance and wear resistance are strong: the O-shaped sealing ring adopts the ethylene propylene diene monomer silicone rubber, and the silicone rubber is a novel heat-resistant high-molecular elastic material, has excellent aging resistance and wear resistance, and is more stable and reliable when in contact with the screw sleeve.
3. Isolation and sealing: the invention is fully embodied in that when the screw sleeve is pushed into the O-shaped sealing ring, the silicon rubber O-shaped sealing ring can play a full sealing role, the phenomenon of resin filling generated by gaps is compensated, the workload and the working strength of operators in related procedures are reduced, and the production efficiency is improved.
