[0002] A casting mold refers to a structure that is first made of other easily moldable materials in the shape of a part in order to obtain the structural shape of the part. Then, the mold is placed in a sand mold, and a cavity with the same structural dimensions as the part is formed in the sand mold. Next, a fluid with fluidity is poured into the cavity, and after the fluid cools and solidifies, a part with exactly the same shape and structure as the mold is formed. The casting mold is an important part of the casting process.
[0003] Since the undercut of the sand core mold cannot be changed and the cost of making a core-pulling slider is relatively high, an insert similar to a movable block needs to be installed in the mold to solve the undercut problem. Content of the Utility Model

[0009] To achieve the effect of controlling the opening and closing of the mold, as a casting device with a movable block of the utility model, a second hydraulic rod is fixedly connected to the inner wall of the lower surface of the lower mold base, and a third hydraulic rod is fixedly connected to the inner wall of the upper surface of the upper mold base.
[0010] To achieve the effect of facilitating the placement of the device, as a casting device with a movable block of the utility model, the bottom of the second hydraulic rod is fixedly connected with a bottom frame, and the upper surface of the third hydraulic rod is fixedly connected with a top frame.
[0011] In order to achieve the effect of limiting the position of the device after it is placed, as a casting device with a movable block of the utility model, a limiting groove first is provided on the lower surface of the bottom frame, and a limiting groove second is provided on the upper surface of the top frame.
[0012] In order to facilitate the flipping of the device, as a casting device with a movable block of the utility model, a rotating rod is fixedly connected to the inner wall of the bottom frame.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. The casting device with a movable block is provided with a negative plate, a hydraulic rod, a movable block body, a molding cavity, a sand core and an undercut groove. The metal liquid enters the molding cavity from the pouring port, and the movable block body can buckle the undercut position to facilitate the molding of the undercut groove.

Therefore, when the undercut of the sand core mold cannot be changed, the undercut problem can be solved in a low-cost and simple way.
[0015] 2. The casting device with movable blocks is installed on a gravity casting machine through the arrangement of a pouring port, a liquid storage dish, a bottom frame, a top frame and a rotating rod. The rotating rod on the bottom frame is rotatably connected to the gravity casting machine. After pouring molten metal into the liquid storage dish, the device is rotated ninety degrees clockwise with the rotating rod as the center of the circle, so that the molten metal in the liquid storage dish enters the molding cavity from the pouring port and is reset when the mold is removed, thereby facilitating the production of molded parts.
