Abstract
Description
Technical Field
[0001] The utility model relates to a device for casting a differential, in particular to a mold for casting a differential housing, and belongs to the technical field of automobile part processing. Background Art
[0002] When casting and processing automobile parts, a stamping device is used to press and fix the sand mold, and then casting liquid is poured into the mold through a pouring port. After the casting liquid inside the sand mold solidifies, the stamping device is used to lift the upper sand mold. At this time, since the casting still has a too high residual temperature, the staff will place a receiving plate on the lower sand mold and knock on the upper sand mold until the casting is lifted onto the receiving plate; during this process, using the manual material receiving method has certain safety hazards. When the staff places the receiving plate, there is an easy safety hazard of the casting falling; in addition, when the upper sand mold is lifted, the distance between the upper and lower sand molds is relatively large. When the casting falls on the lower sand mold, both the lower sand mold and the casting will be deformed. Summary of the Utility Model

A cylinder is arranged above the displacement plate, and a sand mold is arranged below the displacement plate. Two brackets are arranged on both sides in front of the sand mold. The brackets are distributed in an L shape. The bottom of the front end of the brackets is inserted into a second base. A push plate is slidably connected to the upper end of the brackets. A handle penetrates through the push plate, and a receiving plate is arranged at the rear end of the handle. A U-shaped enclosing plate is arranged around the receiving plate.
[0006] Displacement sleeves are sleeved on the lower parts of the two columns at the front end. The displacement sleeves are fixedly connected to the columns by bolts. A positioning sleeve is arranged on the front end face of the displacement sleeves. The rear ends of the brackets are inserted into the positioning sleeves and fixed by bolts outside the positioning sleeves.
[0007] The lower ends of the brackets are inserted into the second base and fixed by bolts.
[0008] There are two handles, which are respectively located on both sides of the middle part of the push plate. The handles penetrate through the push plate, and a material receiving plate is welded at the rear ends of the two push plates.
