Description

Technical Field

[0001] The utility model relates to the field of automobile mold positioning tooling, in particular to a rapid positioning angle tooling. Background Art

[0002] The lifter block in the automotive mold is also called the tilted tip or the tilted ejector. The lifter block is usually used as the inner buckle position, and together with the outer buckle position (slide position), it helps the product to be smoothly demolded from the mold. The design of the lifter block needs to take into account many factors, such as the direction of demolding, mold opening angle, the height of the top of the lifter block, demolding angle, ejection deflection, etc. In general, the lifter block plays an important role in the automotive mold and is one of the key factors to ensure product quality and production efficiency.

[0003] In the past, the inclined ejector block of the automobile mold could only be processed by wire cutting, NC swing angle, mold overall assembly, etc. because its ejection angle was not in the vertical direction. The bottom surface shape had an angle, which made it impossible to clamp the top surface properly using an ordinary three-axis CNC machine tool. This resulted in long processing time, poor processing accuracy, and great processing difficulty. Utility Model Content

[0004] In order to overcome the deficiencies of the above-mentioned prior art, the utility model provides a quick positioning angle tooling to solve the problem in the background technology that the bottom surface shape has an angle, resulting in the top surface shape being unable to be clamped normally using an ordinary three-axis CNC machine tool, resulting in long processing time, poor processing accuracy, and great processing difficulty.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a quick positioning angle tool, comprising a workbench and a tilted top block with a threaded mounting groove at the bottom, a universal seat with a semicircular cross-section embedded in the bottom of the workbench, a locking screw threadedly connected through the universal seat from bottom to top, the top of the locking screw penetrates to the top of the workbench and can be threadedly connected to the mounting groove of the tilted top block, the universal seat can roll on the bottom of the workbench to drive the locking screw to tilt at an angle, so that the locking screw is threadedly connected to the tilted top block, and a plurality of universal seats can be embedded in the bottom of the workbench.

[0006] Preferably, the workbench is rectangular, a rectangular groove penetrating two short side surfaces is provided in the middle of the bottom of the workbench, a receiving groove of the same length as the groove is provided inside the groove, a through groove is provided on the top of the workbench, and the through groove is connected to the receiving groove.

[0007] Preferably, the cross-section of the accommodating groove is semicircular and matches the cross-section of the universal seat, and the length of the accommodating groove is greater than the length of the universal seat.

[0008] Preferably, a threaded connection groove running through the top and bottom is provided at the center of the universal seat, and the diameter of the connection groove is smaller than the width of the through groove.

[0009] Preferably, a support plate close to the accommodating groove is fixed inside the groove, and an opening for accommodating the locking screw to pass through is formed in the middle of the support plate.

[0010] Preferably, positioning grooves are provided on both sides of the short sides of the workbench, and positioning holes penetrating the positioning grooves are provided on both sides of the short sides of the top of the workbench.

[0011] Compared with the prior art, the beneficial effects that the utility model can achieve are: the practical angle tooling of the utility model mainly includes three components: a workbench, a universal seat and a locking screw, wherein the universal seat is in the shape of a semicircular block, embedded in the bottom of the workbench through a semicircular surface, a through groove exposing the universal seat is opened on the top of the workbench, and a threaded connecting groove is opened through the universal seat from top to bottom, and the locking screw can be threaded through the universal seat from the bottom of the workbench to the top of the workbench. Since the universal seat is in the shape of a semicircular block, it can be rolled on the bottom of the workbench to adjust the angle of the locking screw, so that the angle of the locking screw matches the mounting groove of the inclined top block, thereby easily connecting and installing the inclined top block, and quickly positioning the inclined top on the workbench; compared with traditional inclined top head processing, the angle tooling can shorten the processing time, improve the processing accuracy, and reduce the difficulty of clamping, and after arranging multiple universal seats and locking screws, multiple inclined top blocks can be processed at the same time.

[0018] Embodiment:

[0019] like Figure 1-4 As shown, the utility model provides a fast positioning angle tool, including a workbench 1 and an inclined top block 9 with a threaded mounting groove 10 at the bottom, a universal seat 6 with a semicircular cross section is embedded at the bottom of the workbench 1, a locking screw 8 is threadedly connected to the universal seat 6 from bottom to top, the top of the locking screw 8 passes through the top of the workbench 1 and can be threadedly connected to the mounting groove 10 of the inclined top block 9, the universal seat 6 can roll at the bottom of the workbench 1 to drive the locking screw 8 to tilt, so that the locking screw 8 is threadedly connected to the inclined top block 9, and a plurality of universal seats 6 can be embedded at the bottom of the workbench 1;

[0020] Among them, the size and material of the workbench 1 can be 400mm*150mm*50mm 45# steel, quenched and hardened to HRC42°, the diameter of the universal seat 6 can be 30mm, and the connecting groove 7 of the universal seat 6 and the installation groove 10 of the inclined top block 9 can be M8 screw holes and grooves.

[0021] In this embodiment, specifically, the workbench 1 is rectangular, and a rectangular groove 4 running through two short side surfaces is opened in the middle of the bottom of the workbench 1, and a receiving groove 3 with the same length as the groove 4 is opened inside the groove 4, and a through groove 2 is opened on the top of the workbench 1, and the through groove 2 is connected with the receiving groove 3.

[0022] In this embodiment, specifically, the cross section of the receiving groove 3 is semicircular and matches the cross section of the universal seat 6, and the length of the receiving groove 3 is greater than the length of the universal seat 6;
