Through calibration, the scrap rate can be reduced, the mold life can be extended, and the consistency and reliability of the production process can be ensured. After mold drilling, measuring tools such as calipers and micrometers are used to measure and calibrate information such as the position, depth, and shape of the holes. When there are a large number of holes on a mold, the measurement process at multiple positions is relatively cumbersome and it is also difficult to maintain the continuity of the measurement process. Content of the Utility Model
[0003] The purpose of the utility model is to provide a drilling calibration tool for a mold, which can conveniently and continuously measure the positions of a large number of holes on the same mold with the same reference.
[0004] The described drilling calibration tool for a mold includes a base. Above the base, two support frames are longitudinally arranged at left and right intervals and symmetrically distributed. A first scale is horizontally arranged inside the support frames. The two ends of the first scale are respectively in front-back sliding fit connection with the support frames on both sides.
[0005] Support rods are horizontally installed inside the support frames on both the front and back sides of the first scale. The left ends of the support rods are all fixed to the support frame on the left side, and the right ends are all fixed to the support frame on the right side. The first scale slides back and forth between the front and back support rods.
[0006] A second scale is longitudinally arranged between the two support rods. The two ends of the second scale are respectively in left-right sliding fit connection with the support rods on both sides. The first scale and the second scale are vertically distributed and cross each other. A slider is arranged at the intersection point. Both the first scale and the second scale independently pass through the slider. A positioning head that can be telescopically extended up and down is connected to the bottom of the slider.

Move the slider left and right, and the slider drives the second scale to slide back and forth along the support rod. After the slider moves, the positioning head is aligned with the corresponding hole vertically and horizontally. Read the numbers on the first scale and the second scale at this position to obtain the position dimension of the hole. It can conveniently and continuously measure the positions of a large number of holes, and can also ensure that all measured data are derived from the same reference, reducing errors.
[0009] Furthermore, grating scales are installed on both the first scale and the second scale, and a digital display screen is installed on the slider corresponding to the grating scales.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of this design scheme.
[0051] Embodiment
[0052] The following materials are used in this embodiment:
[0053] 1. The base 1 is made by casting. As shown in Figure 3 and Figure 4 , the base 1 has a square block structure, and a number of first chutes 15 that are horizontally uniformly spaced and communicate left and right are opened on the base 1. Five are opened in this embodiment.
[0054] 2. Manufacture the stopper 2 by casting. Threaded holes 16 corresponding to the left and right of the first chute 15 are machined on the stopper 2, and the threaded holes 16 are arranged to communicate with each other from left to right. As Figure 6 shown, there are five threaded holes 16, and the length of the stopper is equal to the length of the left side of the base 1.
[0055] 3. Prepare several metal rods, machine external threads on their outer side walls, and connect handles for easy rotation at the right ends respectively to serve as the first threaded rods 3. The number of the first threaded rods 3 is the same as that of the first chutes 15.
[0056] 4. Manufacture the square frame 4 by casting or welding. As Figure 17 shown, the square frame 4 can be flush with the periphery of the top surface of the base 1. A first through hole 17 is machined at each of the four corners at the top of the square frame 4. As Figure 7 shown, the first through hole 17 is located at the corners of the four right angles.
[0057] 5. Manufacture four support columns 5 by casting or welding. As Figure 15 shown, an annular retaining piece 6 is fixed at a position close to the upper end of the support column 5.
[0058] 6. Prepare two support frames 7 made of a relatively light metal material. Combining Figure 1 、 Figure 2 、 Figure 11 、 Figure 12 、 Figure 17 and Figure 18 shown, the main structure of the support frame 7 is a square column. Second through holes 21 that communicate with each other from top to bottom are opened at both ends of the support frame 7. As Figure 11 shown, the second through holes 21 are used for the upper ends of the support columns 5 to pass through independently; fixing grooves 23 are opened at positions close to the front and rear ends on the inner side of the support frame 7 for installing the support rods 9, and a longitudinal second chute 22 is opened at the middle position for the end of the first scale 8 to slide back and forth.
[0059] 7. Prepare two relatively light metal square rods for making the first scale 8. As Figure 8 shown, a section of the second threaded rod 18 is welded horizontally at the center of each end face of the first scale 8, and a grating scale 19 is arranged on one side of the second scale 14.
[0060] 8. Prepare two relatively light metal square rods as the support rods 9, and both ends of them can be inserted into the fixing grooves 23.
[0061] 9. Manufacture the fixing claws 10 by casting. The number of the fixing claws corresponds to that of the first chutes 15. As Figure 5 shown, its structure is a block with a convex left end. The thickness of the fixing claw 10 is the same as the width of the first chute 15, and it can slide left and right in the first chute 15.
[0062] 10. Prepare a telescopic rod 11. As Figure 16 shown, a positioning head 26 is fixed at the lower end of the telescopic rod 11. The positioning head 26 is in a conical structure, which facilitates the lower end of the positioning head 26 to extend into the measurement hole on the mold for convenient positioning.
[0063] 11. Manufacture the slider 13. As Figure 13 shown, a fourth through hole 24 communicating front and back is machined in the lower half of the slider, and the second scale 14 can pass through independently; a fifth through hole 25 communicating left and right is opened in the upper half. As Figure 14 shown, the fifth through hole 25 ensures that the first scale 8 can pass through independently. As Figure 13 shown, a connecting pipe 12 is vertically fixed on the lower end surface of the slider 13, and internal threads are machined on the inner wall of the connecting pipe 12. Sensors are arranged in both the fourth through hole 24 and the fifth through hole 25, which can read the scale of the grating ruler 19. A digital display screen for displaying the scale values of the first scale 8 and the second scale 14 is installed on the slider 13.
[0064] 12. Prepare a light metal square plate and manufacture the second scale 14. Slide holes 20 communicating left and right are machined at both the front and rear ends of the second scale 14. As Figure 10 shown, the size of the slide hole 20 is such that the support rod 9 can pass through independently. As Figure 9 shown, a grating ruler 19 is arranged on one side surface of the second scale 14.
[0065] The assembly method of the above materials is as follows:
[0066] 1. First, thread the first threaded rod 3 with the threaded hole 16. As Figure 1 and Figure 2 shown, the fixed claw 10 is connected to the left end of the first threaded rod 3, and the two are in a rotational fit connection. The first threaded rod 3 can rotate back and forth relative to the fixed claw 10. Specifically, it can be rotationally connected through a bearing, or an annular limiting groove is opened at the right end of the fixed claw 10, and the left end of the first threaded rod 3 is located in this annular limiting groove. Rotate the first threaded rod 3 back and forth, and the first threaded rod 3 moves left and right along the threaded hole 16, driving the fixed claw 10 to move left and right.
[0067] 2. As Figure 1 shown, place the base 1 flat with the first chute 15 facing up. Align and insert the fixed claw 10 into the first chute 15. The bottom of the fixed claw 10 is in a left-right sliding fit connection with the first chute 15. Align the stop block 2 with the right side surface of the base 1 and fix it.
[0068] 3. As Figure 17 shown, align the square frame 4 with the base 1 and then fix it. Align the support column 5 with the first through hole 17 on the square frame 4 and insert it, and keep the retaining piece 6 at the upper end.
[0069] 4. First, insert the second scale 14 into the fourth through-hole 24, and then insert the support rods 9 into the sliding holes 20 at both ends of the second scale 14. As Figure 18 shown, insert the support rods 9 into the fixing grooves 23 on the support frames 7. Insert one end of the first scale 8 through the second sliding groove 22 and the fifth through-hole 25 in sequence, and mount the first scale 8 on the slider 13 between the two support frames 7. Keep both end faces of the first scale 8 horizontally aligned with the support frames 7. Mount a nut on each of the second threaded rods 18 outside the support frames 7 to limit the first scale 8 so that the first scale 8 can only slide back and forth along the second sliding groove 22. The left and right ends of the support rods 9 are fixed in the fixing grooves 23 inside the support frames 7.
[0070] 5. Align the upper end of the telescopic rod 11 with the connecting pipe 12 and then connect them by thread fitting. Specifically, an external thread that is in thread fit with the internal thread of the connecting pipe 12 is processed at the upper end of the telescopic rod 11, and the upper end of the telescopic rod 11 is screwed into the internal thread of the connecting pipe 12 for connection.
[0071] The usage instructions are as follows:
[0072] Taking the left front corner of the square frame 4 as the zero scale line position as an example to illustrate the usage method. Slide the slider 13 to the left front corner position of the square frame 4. At this time, the left end zero scale line of the first scale 8 and the right angle vertical line of the square frame 4 at this position are on the same straight line, and the front end zero scale line of the second scale 14 and the right angle vertical line of the square frame 4 at this position are on the same straight line. After calibrating the zero scale lines of the first scale 8 and the second scale 14, place the mold in the square frame 4 and align it with the zero scale line as the reference. Move the fixed claw 10 to the left and then clamp and fix the mold. Move the slider 13 backward or to the right, and the positioning head 26 moves downward and aligns with the hole to be measured. Read the scales on the first scale 8 and the second scale 14 to obtain the position of the hole relative to the zero scale line; other methods can also be used to measure the measurement position of the mold during actual measurement.
[0073] When in use, as Figure 1 shown, place the mold to be measured on the upper surface of the base 1, and then rotate the first threaded rod 3. Since the first threaded rod 3 is in thread fit with the threaded hole 16, the first threaded rod 3 moves to the left while rotating, and then pushes the fixed claw 10 to press the mold tightly. Then translate the slider 13 above the hole to be measured, pull down the positioning head 26, and press against the orifice of the hole to be measured, making the positioning head 26 as close as possible to the orifice to ensure accurate positioning of the axis of the hole. Then record the data read from the grating scales 19 on the first scale 8 and the second scale 14 displayed on the digital display screen on the slider 13. This tool can conveniently and continuously measure the positions of a large number of holes, and can also ensure that all measured data are derived from the same reference, which can reduce errors.
