Description

Technical Field

[0001] The utility model relates to the technical field of jewelry processing, in particular to a mold holding and polishing processing fixture. Background Art

[0002] Moulding is a metal processing technology, mainly used for trimming jewelry castings to achieve beautiful shapes and smooth surfaces. The tools used in the moulding process include hoists, welding tools, files, bow saws, etc. The hoists are used to cooperate with milling cutters and sandpaper for grinding and drilling, welding tools are used to weld separated parts, files are used to trim burrs and uneven places, and bow saws are used to saw off the sprues or change the size of the ring.

[0003] Every piece of jewelry that is molded needs to be done by hand to ensure it meets the design requirements and customer satisfaction.

[0004] In the prior art, the Chinese utility model with publication number: CN219725980U discloses a fixture for jewelry processing, including a column with a block installed on the top of the column. The utility model is equipped with a stud, and the staff puts the external ring on the outside of the placement groove, and then grabs the stud and inserts it into the inner side of the rubber ring, so that the stud is accurately moved to the position of the screw hole under the guidance of the guide groove. The staff grabs the rotating plate and rotates it, so that the rotating plate drives the stud to rotate through the extrusion block, so that the stud moves to the back side by the thread action with the screw hole, and the stud drives the extrusion block to rotate and move to the back side, and the extrusion block expands the part of the rubber ring close to the front side to support and fix the external ring. At this time, the outer side of the ring is completely exposed to the outside, which is convenient for the staff to carry out continuous processing and improves flexibility.

[0005] The above technical solution places the ring to be processed in the placement groove, utilizes the stud to be threadedly connected with the screw hole, drives the extrusion block to squeeze the inner side of the rubber ring, and squeezes and limits the ring in the storage groove. This clamping method is limited by the size of the rubber ring and the storage groove, and the size of the clamped ring is limited. At the same time, the ring clamped in this way is in contact with the rubber ring on the inside and outside, which reduces the processing surface of the ring and makes the ring processing very inconvenient.

Two sets of limiting rings 11 are fixed on the surface of the screw rod 5. The limiting rings 11 and the screw sleeve 9 are located on both sides of the open groove 3. The screw rod 5 is limited by the cooperation between the screw rod 5 and the screw sleeve 9 and the limiting rings 11 at the same time, so that the screw rod 5 drives one side of the circular column 2 to move relative to the other side through the screw sleeve 9, so as to meet the purpose of the circular column 2 approaching inward and expanding outward.

[0034] The opening groove 3 and one side of the circular column 2 are both provided with a receiving groove 12, and the limiting ring 11 is located in the inner cavity of the receiving groove 12.
