Description

Technical Field

[0001] The utility model relates to the technical field of MIM-related accessories, and in particular to a special ornament fixture for spherical products. Background Art

[0002] Metal injection molding (MIM) is a molding method that injects a plasticized mixture of metal powder and its binder into a mold. It first mixes the selected powder with the binder, then granulates the mixture and injects it into the desired shape. The polymer imparts its viscous flow characteristics to the mixture, which helps to form, fill the mold cavity and ensure uniformity of powder loading. After forming, the binder is removed and the degreased blank is sintered. In the production process of specific products, for example, the injection blank of a spherical product needs to be placed on a sintering support made of ceramic material before entering the degreasing sintering furnace. However, since the product is spherical, it cannot be fixed on a flat sintering plate. It is necessary to open a hole on the sintering plate and add a chamfer to stabilize the product. The existing solution is to manually hold the product by hand and visually place it on the sintering plate. Such manual operation is difficult to achieve neat placement, and the stability is not high, and the consistency cannot be guaranteed. The efficiency of manual placement is also low, and the sintered product has abnormalities.

[0003] Based on the above situation, our company carried out corresponding technical transformation after sufficient comparison and demonstration, and developed and designed a special ornament fixture for spherical products. Utility Model Content

[0009] Bosses are provided inwardly on both side walls of the base to match the sintering plate;

[0010] The sintering plate is provided with a fixing hole matched with the V-shaped groove of the outer contour of the sphere on the base.

[0011] Preferably, the base and the sintering plate are clearance-matched; and a single-side avoidance gap of 0.05 mm is provided between the length and width directions of the sintering plate and the side edge of the sintering plate.
