[0002] Mold Making refers to the processing of forming and blanking tools, and also includes shearing dies and die-cutting dies. Usually, the mold consists of two parts: the upper die and the lower die. The steel plate is placed between the upper and lower dies, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the shape of the mold is obtained or the corresponding waste is removed. Workpieces as small as electronic connectors and as large as car dashboards can be formed by molds. Progressive die refers to a set of molds that can automatically move the workpiece from one station to another and obtain a molded part at the last station. Mold processing technology includes: cutting die, blanking die, compound die, extrusion die, four-slide die, progressive die, stamping die, die-cutting die, etc.

[0003] However, in practical applications, most of the existing tubular molds are fixed in place by extrusion and clamping during grinding operations. However, the extrusion and clamping method makes it impossible to adjust the position of the tubular mold during processing, resulting in heavy processing and multiple disassembly and assembly to change the fixed position of the tubular mold to cooperate with the processing, which will waste a lot of time and reduce work efficiency, which is not conducive to promotion and use.

[0004] Therefore, those skilled in the art provide a positioning fixture for mold processing to solve the problems raised in the above background technology. Utility Model Content

At this time, the two first support rollers 5 and the two second support rollers 6 gradually move away from each other as the threaded bolts 7 rotate, until the two first support rollers 5 and the two second support rollers 6 respectively drive the support sleeve 8 to contact the inner wall of the tubular workpiece, thereby completing the extrusion, fixing and positioning of the tubular workpiece. At the same time, the rotatability of the support sleeve 8 can make the tubular workpiece still rotatable in a fixed state, avoiding repeated disassembly and assembly for position adjustment, thereby saving a lot of time and improving work efficiency.

[0021] In the present application, two rectangular plates 9 are connected to the inner wall of the rectangular hole in a sliding manner up and down, a motor 10 is fixedly connected to the right side of one of the two rectangular plates 9, a bidirectional screw rod 11 is fixedly connected to the output shaft of the motor 10, and the two mounting plates 3 are both connected to the bidirectional screw rod 11 through a spiral transmission; by setting the bidirectional screw rod 11, when the motor 10 generates a drive to drive the bidirectional screw rod 11 to rotate, the spacing between the two mounting plates 3 can be adjusted, thereby improving the scope of application for tubular workpieces of different sizes and reducing limitations.

[0022] In the present application, a threaded rod 12 is spirally connected to the left side of one of the two rectangular plates 9, and the top of the threaded rod 12 is rotatably connected to the bottom side of the support platform 1; by setting the threaded rod 12, the threaded rod 12 can drive the mounting plate 3 to lift upward in cooperation with the bidirectional screw rod 11 when rotating, and then can drive the positioned tubular workpiece to lift, so that the height of the tubular workpiece can be adjusted according to the height of different people after positioning, thereby improving the convenience of processing operations.

At the same time, the rotatability of the support sleeves 8 can be used to allow the tubular workpiece to still rotate in a fixed state, avoiding repeated disassembly and assembly for position adjustment, thereby saving a lot of time and improving work efficiency. When the output shaft of the motor 10 drives the bidirectional screw rod 11 to rotate, the rotation of the bidirectional screw rod 11 can adjust the spacing between the two mounting plates 3. , thereby increasing the scope of application for tubular workpieces of different sizes and reducing limitations. The threaded rod 12 is manually driven to rotate, and the threaded rod 12 drives the rectangular plate 9 to move upward. The two-way screw rod 11 can be used to drive the two mounting plates 3 to be lifted upward at the same time, thereby driving the positioned tubular workpiece to be lifted, so that the height of the tubular workpiece can be adjusted according to the height of different people after positioning, thereby improving the convenience of processing operations. When the two mounting plates 3 move left and right or adjust the height up and down, the guide rod 13 can be used to keep the mounting plate 3 moving in the horizontal direction, and at the same time, it can also keep synchronous up and down adjustment to avoid offset. The rubber pad can increase the friction between the support leg 2 and the ground while reducing the noise generated by vibration, thereby alleviating noise pollution.
