A hole spacing detection device for precision mold production

Abstract

This utility model relates to the field of hole spacing detection technology, specifically to a hole spacing detection device for precision mold production. It includes a detection base with locking blocks on both sides of its top. Slider blocks are slidably mounted on opposite sides of the locking blocks. A detection component for detecting the hole spacing of the mold is movably mounted between the two sliders. A placement frame is located on the top of the detection base, and the mold with the hole spacing to be detected is movably mounted inside the placement frame. By pressing down on the measuring rod, if the irregular block and indicator block do not protrude outwards from the measuring rod, it indicates that the hole spacing of the mold is just right. If the irregular block and indicator block protrude outwards from the measuring rod, it indicates that the hole spacing is too large. This allows for the rapid detection of hole spacing slightly larger than the measuring rod. Simultaneously, by using the indicator block on the top of the irregular block in conjunction with the scale lines, the actual difference between the hole spacing and the measuring rod can be detected, facilitating subsequent adjustments.

Description

Technical Field

[0001] This utility model relates to the field of hole spacing detection technology, specifically to a hole spacing detection device for precision mold production. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. Molds are tools used to create shaped objects, and these tools are composed of various parts; different molds are composed of different parts.

[0003] Chinese Patent Publication No. CN217637132U discloses a hole spacing detection device for precision mold production, belonging to the technical field of detection devices. It includes a main body with a sliding groove inside, a product placed in the middle of the groove, a measuring plate at the upper end of the main body, and a convenient replacement component on one side of the measuring plate. This invention, by providing a convenient replacement component, enables easy replacement of the measuring plate, thereby improving the efficiency of measuring plate replacement. When different models of products need to be tested, the measuring plate can be quickly replaced, making the device suitable for different product models and improving its applicability. Simultaneously, the structure is simple to operate and convenient for operators, thus improving ease of use. It also provides auxiliary limiting of the product, preventing accidental movement of the product during testing.

[0004] The aforementioned device uses a measuring rod to connect to a through hole in the mold. When the measuring rod cannot be inserted into the through hole inside the mold, it indicates that the through hole is defective. However, if a through hole with a diameter larger than the measuring rod is encountered, especially a through hole with a diameter only slightly larger than the measuring rod, it is impossible to quickly determine whether the through hole is qualified. Utility Model Content

[0005] To address the aforementioned issues, a hole spacing detection device for precision mold production is provided. By pressing the measuring rod downwards, if the irregular block and the indicator block do not protrude outwards from the measuring rod, it indicates that the hole spacing of the mold is just right. If the irregular block and the indicator block protrude outwards from the measuring rod, it indicates that the hole spacing is too large. This allows for the rapid detection of hole spacing slightly larger than the measuring rod. Simultaneously, by utilizing the indicator block on the top of the irregular block in conjunction with the scale lines, the actual difference between the hole spacing and the measuring rod can be detected, facilitating subsequent adjustments.

[0006] To address the existing technical problems, this utility model provides a hole spacing detection device for precision mold production, including a detection base. Each detection base has two locking blocks on its top sides, and two sliders are slidably mounted on opposite sides of the locking blocks. A detection component for detecting the hole spacing of a mold is movably mounted between the two sliders. A placement frame is provided on the top of the detection base, and a mold with the hole spacing to be detected is movably mounted inside the placement frame.

[0007] Preferably, the detection assembly includes a mounting frame movably disposed between two sliders, a measuring rod movably disposed inside the mounting frame, a guide rod disposed inside the measuring rod, irregularly shaped blocks movably disposed at both ends of the guide rod, and a compression spring sleeved on the outside of the guide rod, with both ends of the compression spring connected to the side walls of the two irregularly shaped blocks respectively.

[0008] Preferably, the sidewalls of the irregularly shaped block are set as inclined surfaces.

[0009] Preferably, an indicator block is provided on the top of the irregularly shaped block, a calibration block is provided on the outer wall of the measuring rod, and a scale line is provided on the outer wall of the calibration block to cooperate with the indicator block.

[0010] Preferably, a pressure plate is provided at the top of the measuring rod, and a compression spring is sleeved on the outside of the measuring rod. One end of the compression spring is connected to the bottom of the pressure plate, and the other end of the compression spring is connected to the top of the mounting frame.

[0011] Preferably, pull rods are movably provided on both outer walls of the mounting frame, a positioning pin is provided at one end of the pull rod, a positioning spring is sleeved on the outside of the pull rod, one end of the positioning spring is connected to the side wall of the positioning pin, the other end of the compression spring is connected to the inner wall of the mounting frame, and a positioning groove adapted to the positioning pin is provided on the outer wall of the slider.

[0012] The advantages of this utility model compared to the prior art are:

[0013] 1. By pressing the measuring rod downwards, if the irregular block and the indicator block do not protrude outwards from the measuring rod, it indicates that the hole spacing of the mold is just right. If the irregular block and the indicator block protrude outwards from the measuring rod, it indicates that the hole spacing is too large. This allows for quick detection of hole spacing that is slightly larger than the measuring rod. At the same time, by using the indicator block on the top of the irregular block in conjunction with the scale line, the actual difference between the hole spacing and the measuring rod can be detected, facilitating subsequent adjustments.

[0014] 2. By placing the measuring rod for testing between the two sliders, pulling the lever to move the positioning pin, and then inserting the positioning pin into the positioning groove on the side wall of the slider, the mounting frame and measuring rod can be installed between the two sliders under the action of the positioning spring, which is convenient for measuring the mold and also convenient for changing measuring rods of different sizes, so that molds with different hole spacings can be tested.

Detailed Implementation

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 6 As shown, this utility model provides:

[0024] A hole spacing detection device for precision mold production includes a detection base 1. Both sides of the top of the detection base 1 are provided with a locking block 2. A slider 15 is slidably provided on the opposite side of the two locking blocks 2. A detection component for detecting the hole spacing of the mold is movably arranged between the two sliders 15. A placement frame 3 is provided on the top of the detection base 1. The mold with the hole spacing to be detected is movably arranged inside the placement frame 3.

[0025] By placing the mold to be inspected inside the placement frame 3, and then placing the measuring rod 5 for inspection between the two sliders 15, it is convenient to inspect the hole distance of the mold. Then, the inspection component can quickly detect the hole distance that is slightly larger than the measuring rod 5.

[0026] like Figure 5 As shown, the detection assembly includes a mounting frame 4 movably disposed between two sliders 15. A measuring rod 5 is movably disposed inside the mounting frame 4. A guide rod 16 is disposed inside the measuring rod 5. Shaped blocks 14 are movably disposed on the outside of both ends of the guide rod 16. A compression spring 17 is sleeved on the outside of the guide rod 16. The two ends of the compression spring 17 are respectively connected to the side walls of the two shaped blocks 14.

[0027] By pressing the measuring rod 5, if the irregular block 14 and the indicator block 13 do not protrude outwards from the measuring rod 5, it indicates that the hole spacing of the mold is just right. If the irregular block 14 and the indicator block 13 protrude outwards from the measuring rod 5, it indicates that the hole spacing is too large. In this way, a hole spacing slightly larger than the measuring rod 5 can be quickly detected.

[0028] like Figure 5 As shown, the sidewalls of the irregular block 14 are set as slopes.

[0029] By setting the irregular block 14 as an inclined surface, it is convenient for the through hole on the mold to extrude the irregular block 14.

[0030] like Figure 5 As shown, an indicator block 13 is provided on the top of the irregular block 14, a calibration block 11 is provided on the outer wall of the measuring rod 5, and a scale line 12 that works in conjunction with the indicator block 13 is provided on the outer wall of the calibration block 11.

[0031] By using the indicator block 13 on the top of the irregular block 14 in conjunction with the scale line 12, the actual difference between the hole distance and the measuring rod 5 can be detected, which facilitates later adjustment.

[0032] like Figure 3 As shown, a lower pressure plate 10 is provided on the top of the measuring rod 5, and a compression spring 9 is sleeved on the outside of the measuring rod 5. One end of the compression spring 9 is connected to the bottom of the lower pressure plate 10, and the other end of the compression spring 9 is connected to the top of the mounting frame 4.

[0033] By utilizing the elastic force of the compression spring 9, the measuring rod 5 can always remain above the placement frame 3, facilitating the detection of the hole spacing.

[0034] like Figure 3As shown, pull rods 8 are movably installed on both outer walls of the mounting frame 4. A positioning pin 6 is provided at one end of the pull rod 8. A positioning spring 7 is sleeved on the outside of the pull rod 8. One end of the positioning spring 7 is connected to the side wall of the positioning pin 6. The other end of the compression spring 17 is connected to the inner wall of the mounting frame 4. The outer wall of the slider 15 is provided with a positioning groove that matches the positioning pin 6.

[0035] Pulling the lever 8 moves the positioning pin 6, and then inserts the positioning pin 6 into the positioning groove on the side wall of the slider 15. Under the action of the positioning spring 7, the mounting frame 4 and the measuring rod 5 can be installed between the two sliders 15, which is convenient for measuring the mold and also convenient for replacing measuring rods 5 of different sizes, so that molds with different hole spacings can be inspected.

[0036] Working principle: When it is necessary to inspect the hole spacing inside the mold, first place the mold to be inspected inside the placement frame 3, then place the measuring rod 5 between the two sliders 15. Next, pull the pull rod 8 to move the positioning pin 6, and then insert the positioning pin 6 into the positioning groove on the side wall of the slider 15. Under the action of the positioning spring 7, the mounting frame 4 and the measuring rod 5 can be installed between the two sliders 15, facilitating mold measurement and allowing for the replacement of measuring rods 5 of different sizes to inspect molds with different hole spacings. Then, press the measuring rod 5 downwards. When the hole spacing inside the mold is smaller than the diameter of the measuring rod 5, it cannot move downwards further. When the hole spacing of the mold is smaller than the diameter of the measuring rod 5, it cannot move downwards further. When rod 5 is properly fitted, the two irregularly shaped blocks 14 and the indicator block 13 inside the measuring rod 5 will also abut against the inner wall of the through hole as they move downwards, causing the irregularly shaped blocks 14 and the indicator block 13 to move closer to each other until they are completely inside the measuring rod 5. When the irregularly shaped blocks 14 and the indicator block 13 do not protrude outwards from the measuring rod 5, it indicates that the hole spacing of the mold is just right. When the irregularly shaped blocks 14 and the indicator block 13 protrude outwards from the measuring rod 5, it indicates that the hole spacing is too large. In this way, a hole spacing slightly larger than the measuring rod 5 can be quickly detected. At the same time, by using the indicator block 13 on the top of the irregularly shaped block 14 in conjunction with the scale line 12, the actual difference between the hole spacing and the measuring rod 5 can be detected, which is convenient for later adjustment.
