[0014] In order to better understand the technical scheme of the utility model, the following through specific example is explained in detail:
[0015] Please refer to Figure 1 The utility model discloses a sand core deburring anti-deformation tool.
[0016] The surface of tool body 1 of tool body is the concave sand core containing structure 2, and the shape of sand core containing structure matches the projection of sand core in the vertical direction, and the sand core is translated after being taken out from the sand core mold, and then is vertically lowered from top to bottom without changing direction and is arranged in sand core containing structure 2.
[0017] The top surface of each type side wall of sand core containing structure 2 is provided with burr cut -out 3. The cutting edge of burr cut -out 3 faces the side parting surface of sand core, and the height of burr cut -out 3 is 3mm higher than the burr position according to the design of sand core parting surface. In the process of core setting, the side burr of parting surface is cut off through the relative movement of sand core and burr cut -out.
[0018] In order to ensure the accuracy of the core setting process of sand core and prevent bumping, sand core positioning structure is arranged on the tool body, and positioning matching structure corresponding to sand core positioning structure is arranged on the sand core. The sand core positioning structure is used for guiding the core setting.
[0019] Specifically, the sand core positioning structure is divided into positioning core head 4 and positioning reference point 5.
[0020] The positioning core head 4 is a cylindrical groove located at the end of one side of the sand core containing structure. The positioning core heads are arranged in two groups, and the positioning core heads in each group are arranged in a straight line at equal intervals. The positioning core heads are located at the same side of the sand core. The positioning reference point 5 is a protruding structure located at the opposite side of the positioning core head.
[0021] The specific implementation steps of the utility model are as follows:
[0022] 1. Place the tooling body on the workbench beside the core making machine.
[0023] 2. After the sand core is taken out from the sand core mold, the sand core is accurately guided by the sand core positioning structure to butt joint with the tooling. First, align the sand core with the position of the positioning reference point 5, and then adjust the direction so that the positioning core head 4 matches the sand core.
[0024] 3. The sand core is vertically downwardly cored, and the sand core is scraped to remove the lateral burrs when the sand core passes through the cut burr cutout.
[0025] 4. The sand core is positioned on the profile positioning surface and cooled and solidified in the positioning reference, thereby ensuring the dimensional accuracy of the sand core body and removing the parting surface burrs.
[0026] The utility model ensures that the sand core does not deform during the cooling and solidification process, removes the burrs, greatly reduces the manual deburring time, reduces the manual burr trimming operation amount, improves the work efficiency and product precision.
