Description

Technical Field

[0001] This utility model relates to the field of sprue cutting technology, and in particular to an improved sprue cutting fixture. Background Technology

[0002] Currently, the main method for cutting sprue marks involves manually placing the product onto a fixture and then using a cutter to remove the sprue mark. During this process, incomplete or missing cuts may occur. Furthermore, inconsistent placement techniques can lead to misaligned products when placing them onto the fixture, resulting in poorly cut sprue marks.

[0003] In view of this, the applicant applied for a Chinese patent in 2021 with authorization announcement number CN215849445U: "A sprue cutting fixture" (hereinafter referred to as prior art 1). During the process of cutting the sprue of the workpiece with a cutter, the workpiece is fixed by a base and a cover plate. The cutting path of the cutter is limited by anti-deviation grooves and push blocks, so that the sprue will not be cut cleanly or incompletely. When the workpiece is placed on the base, the workpiece is positioned by the workpiece positioning groove, so the workpiece will not be placed off-center, and the yield of the workpiece after cutting the sprue is higher.

[0004] However, in actual use, after each workpiece is placed and clamped, it is necessary to manually push the push block to move the cutter to remove the sprue from the workpiece. Although this can meet the basic sprue removal requirements, manual pushing is slow and also means that workers need to operate it continuously, making it impossible to achieve the effect of multiple stations operating at the same time.

[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0011] A driving source is mounted on the same side of the base and the rotating gear, a transmission gear is drivingly connected to the driving source, and the transmission gear is meshingly connected with the rotating gear; when the transmission gear rotates, the rotating gear and the lead screw are driven through meshing; the mounting base drives the cutter to slide horizontally in the deviation-preventing groove and the movable groove through the screwing of the screw hole and the lead screw.

[0012] As a further scheme of the utility model, a fixed piece in the shape of an inverted "L" is arranged on the same side of the push block and the rotating gear, a ball bearing is embedded in the inner wall of the fixed piece, and the rotating gear is rotatably connected with the ball bearing.
