Description

Technical Field

[0001] The utility model relates to the field of high-precision molds, in particular to a high-precision mold positioning and adjusting device. Background Art

[0002] High-precision molds are molds used to process and manufacture high-precision parts or products to ensure that products that meet strict dimensional requirements are produced. High-precision molds rely on precision processing equipment and technology, such as CNC machine tools, grinders, coordinate grinders, etc. Therefore, they need to be positioned during processing to ensure the dimensional accuracy of the mold. This solution specifically involves a high-precision mold positioning and adjustment device;

[0003] When using the existing mold positioning and adjustment device, since it is necessary to position both sides and the front and back parts at the same time, multiple convenient adjustment operations reduce work efficiency, and it is not convenient to position the front and back parts while positioning the both sides. In addition, the positioning of the two sides and the front and back parts of molds of different specifications are not synchronized, and it is not convenient to adjust the positioning width and distance, which has a certain impact on actual use.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a high-precision mold positioning and adjustment device includes a base 1, a positioning mechanism 2 is installed inside the base 1, an adjustment component 3 is installed inside the base 1, the positioning mechanism 2 includes a first screw 4, a worm 5 is fixedly sleeved on the periphery of the first screw 4 near the middle, a turntable 6 is fixedly installed at one end of the first screw 4, slides 7 are movably installed on both ends of the periphery of the first screw 4, a second screw 8 is movably installed inside the base 1 and below the first screw 4, a worm gear 9 is fixedly installed in the middle of the second screw 8, and the same slides 7 are movably installed on both ends of the periphery of the second screw 8, first positioning blocks 10 are installed on the tops of the two horizontal slides 7 and pass through the top of the base 1, and second positioning blocks 11 are installed on the tops of the two longitudinal slides 7 and pass through the top of the base 1.

[0023] In this embodiment, the thread directions at both ends of the outer periphery of the first screw rod 4 are arranged in opposite directions, and the two transverse slide seats 7 are sleeved on the outer periphery of the first screw rod 4 and are threadedly connected. The rotation of the first screw rod 4 allows the two first positioning blocks 10 to slide through the slide seats 7 to position the two sides of the mold.

[0024] In this embodiment, the worm 5 is meshingly connected with the worm wheel 9, and the worm wheel 9 and the second screw 8 are synchronously rotated. The first screw 4 rotates while driving the worm 5 to rotate, and the worm wheel 9 drives the second screw 8 to rotate through meshing.

[0025] In this embodiment, the thread directions at both ends of the outer periphery of the second screw rod 8 are set in opposite directions, and the two longitudinal slide seats 7 are sleeved on the outer periphery of the second screw rod 8 and are threadedly connected. The two second positioning blocks 11 slide through the rotation of the second screw rod 8 to facilitate the positioning of the front and rear directions of the mold.

[0026] In this embodiment, the adjustment component 3 includes two adjustment rods 12, and the two adjustment rods 12 are respectively passed through the interior of the two second positioning blocks 11. A rotating shaft 13 is installed on the periphery of the adjustment rod 12 near the outer end and the inner end. A shaft sleeve 14 is movably installed on the periphery of the two shafts 13. A scale rod 15 is installed between the two shaft sleeves 14 and passes through the interior of the second positioning block 11. A knob 16 is fixedly installed on the outer end of the adjustment rod 12, and a positioning plate 17 is fixedly installed on the inner side of the shaft sleeve 14 at the inner end. The adjustment rod 12 is moved back and forth in the second positioning block 11 under the action of the thread to adjust and position different molds.

[0027] In this embodiment, the adjusting rod 12 passes through the interior of the second positioning block 11 and is threadedly connected. The adjusting rod 12 is movably rotatable in two sleeves 14 through a rotating shaft 13. The adjusting rod 12 rotates in the sleeves 14 through the rotating shaft 13. The sleeves 14 are kept in translation by the scale rod 15 to prevent the positioning plate 17 from rotating with it.

[0028] In this embodiment, the two sleeves 14 are fixed to each other by a graduated rod 15 , and the sleeves 14 and the positioning plate 17 are fixedly installed. The position of the positioning plate 17 is observed and adjusted by the graduated rod 15 , which is suitable for positioning molds of different specifications.

[0029] It should be noted that the utility model is a high-precision mold positioning and adjustment device. When in use, the mold is first placed on the top of the base 1. Since the high-precision mold needs to be positioned and adjusted to the specified position for processing to prevent the cavity from shifting, when positioning, the first screw 4 and the worm 5 are rotated synchronously by rotating the turntable 6, and the slide 7 slides under the action of the thread and drives the first positioning block 10 to slide inward. At the same time, through the engagement of the worm 5 and the worm wheel 9, the second screw 8 and the worm wheel 9 are rotated synchronously, and the slide 7 on the periphery of the second screw 8 slides under the action of the thread and drives the second positioning block 11 to slide inward to clamp the two sides and the front and rear parts of the mold. When molds of different specifications are positioned, the two first positioning blocks 10 on both sides contact and clamp the two sides of the mold, and the two second positioning blocks 11 on the front and rear parts do not contact the mold. When adjusting, the two knobs 16 are rotated respectively to make the adjusting rod 12 slide inward under the action of the thread, and drive the positioning disk 17 to slide inward and contact the mold. The telescopic distance of the two positioning disks 17 is observed and adjusted by the scale rod 15.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
