Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to a riser locking device for molding high-manganese steel using molten glass sand. Background Technology

[0002] In the traditional molding process of casting high manganese steel with water glass sand, the riser position is marked on the mold. When the sand mixer pours water glass sand to the riser position, a layer of pre-mixed olivine sand is placed at the riser position, followed by the placement of the riser sleeve and manual compaction of the olivine sand at the base of the riser. Figure 2 As shown, the disadvantages of traditional molding are: the compactness of the sand mold at the root of the riser is difficult to guarantee, which makes it easy to cause sand erosion during pouring; and the root of the riser is prone to sintering after pouring, which adds a lot of trouble to the subsequent processes. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a riser locking device for molding high manganese steel molten glass sand, which aims to solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a riser locking device for molding high manganese steel molten glass sand, comprising: a mold, a riser sleeve, and a self-made clay core; the self-made clay core is set at the riser of the mold; a riser sleeve is set on the self-made clay core; the riser sleeve is fixed on the mold by a locking mechanism to press the self-made clay core to fit the riser of the mold.

[0005] Furthermore, the surface of the self-made clay core is coated with a paint.

[0006] Furthermore, the locking mechanism includes a pre-embedded nut, a locking screw, a pressure plate, a washer, and a locking nut; the pre-embedded nut is pre-embedded in the mold, and the pressure plate is set inside the riser sleeve; the pressure plate is provided with a through hole; the locking screw passes through the through hole in the pressure plate and is threaded to the pre-embedded nut; the locking screw is provided with a locking nut for tightening the pressure plate.

[0007] Furthermore, a washer is provided between the lock nut and the pressure plate.

[0008] Compared with existing technologies, this utility model has the following advantages: By using a locking mechanism to fix the riser sleeve on the mold and press the self-made clay core, this utility model can effectively improve the compactness and stability of the sand mold at the riser root, fundamentally solving the problem of sand flushing during the casting process; by making the clay core and brushing on the coating, the coating can play an anti-sintering role, and together with the stable fixation of the riser sleeve, the sintering problem at the riser root is basically solved, eliminating the need for additional treatment of the sintered part, greatly reducing the operational difficulty and workload of subsequent processes, improving overall production efficiency, directly reducing the scrap or rework of castings caused by these problems, and ultimately achieving a significant improvement in casting quality.
