Description

Technical Field

[0001] The utility model relates to the technical field of mold frames, in particular to a mold processing mold frame positioning detection device. Background Art

[0002] The mold frame is the supporting component of the mold during the processing. The mold is installed on the mold frame. Through the upper and lower combination, the internal part of the mold can be processed. The mold frame also plays a positioning role in the mold processing process, so high precision requirements are required.

[0003] During the processing of existing mold frames, long-term collisions between molds can easily cause position deviations inside the mold frames. Due to the small fitting tolerances between the mold frames, the internal wear is serious after the offset. However, due to its high precision, it is not easy to be discovered. Therefore, during the processing process, the deviation is often not discovered until it is serious enough to affect the processing quality or the internal deviation is visible to the naked eye. At this time, it is more difficult to repair and correct.

[0004] Therefore, the demand for high-reliability products is imminent. Therefore, we propose a mold processing mold frame positioning detection device, which can remind the staff when the mold frame is offset. Utility Model Content

[0005] The purpose of the present invention is to provide a mold processing mold frame positioning detection device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

The upper surface of the lower mold is fixedly connected to a receiving cylinder that passes through the bottom thereof, and the inner wall of the receiving cylinder is provided with a built-in guide groove.

[0008] A detection column is inserted into the inner wall of the receiving tube near the top, and a detection base is provided at the bottom end of the receiving tube.

A positioning block is fixedly connected to the outer wall of the positioning detection rod, and a force-sensitive resistor is fixedly connected to the upper surface of the positioning detection rod.

[0009] The bottom end of the detection column is fixedly connected to a docking rod, and the bottom end of the docking rod is fixedly connected to a pressure bottom rod adapted to dock with the force-sensitive resistor sheet, and the outer wall of the docking rod does not contact the inner wall of the receiving tube.

[0010] A further improvement of the technical solution of the present invention is that the outer wall of the threaded fastening rod is threadedly connected to the inner wall of the receiving cylinder near the bottom end.

[0011] A further improvement of the technical solution of the present utility model is that the outer wall of the positioning block is plugged into the inner wall of the built-in guide groove.

[0012] A further improvement of the technical solution of the present utility model is that the number of the force-sensitive resistor sheets and the number of the pressure bottom rods are both six groups, and the six groups of force-sensitive resistor sheets are distributed in a ring array on the top of the positioning detection rod.

[0013] A further improvement of the technical solution of the present utility model is that the signal transmission end of the force-sensitive resistor is electrically connected to a control display, and an alarm is provided on one side of the control display.

[0014] A further improvement of the technical solution of the present utility model is that: the top end of the detection column is fixedly connected to the bottom surface of the upper mold, and the upper mold is fixedly connected to the bottom surface of the upper mold frame.

[0015] A further improvement of the technical solution of the present utility model is that: the bottom surface of the upper mold frame is fixedly connected to a cylinder for driving it to open and close the mold.

[0017] The utility model provides a mold processing mold frame positioning detection device, which uses the coordinated use of a detection column, a positioning detection rod, a force-sensitive resistor, a docking rod and a pressure bottom rod. After the mold frame is offset, the pressure distribution of multiple groups of force-sensitive resistors can be accurately detected, and the offset direction of the upper mold frame can be accurately detected, and the staff can be reminded in time through an alarm.

[0018] The utility model provides a mold processing mold frame positioning detection device, which utilizes the coordinated use of a positioning detection rod, a receiving tube, a built-in guide groove, a positioning block, a threaded fastening rod and a detection base to facilitate the installation and disassembly of the positioning detection rod and a force-sensitive resistor.

[0024] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] The present invention is further described in detail below with reference to the embodiments:

[0026] like Figure 1-4 As shown, the utility model provides a mold processing mold frame positioning detection device, including an upper mold frame 1, a lower mold frame 2, a lower mold 3 and an upper mold 4. The upper surface of the lower mold 3 is fixedly connected to a receiving tube 10 that passes through its bottom, and the inner wall of the receiving tube 10 is provided with a built-in guide groove 11.

[0027] A detection column 8 is inserted into the inner wall of the receiving tube 10 near the top, and a detection base 9 is provided at the bottom end of the receiving tube 10. The top of the detection base 9 is fixedly connected to a threaded fastening rod 13 that is docked with the receiving tube 10. The top of the threaded fastening rod 13 is rotatably connected to a positioning detection rod 12. The outer wall of the positioning detection rod 12 is fixedly connected to a positioning block 14, and the upper surface of the positioning detection rod 12 is fixedly connected to a force-sensitive resistor 15.

[0028] The bottom end of the detection column 8 is fixedly connected to a docking rod 16 , and the bottom end of the docking rod 16 is fixedly connected to a pressure bottom rod 17 adapted to dock with the force-sensitive resistor sheet 15 . The outer wall of the docking rod 16 does not contact the inner wall of the receiving tube 10 .

[0029] The outer wall of the threaded fastening rod 13 is threadedly connected to the inner wall of the receiving tube 10 near the bottom end.

[0030] The outer wall of the positioning block 14 is plugged into the inner wall of the built-in guide groove 11. There are four sets of detection bases 9, symmetrically distributed at both ends of the lower mold 3. Each detection base 9 is equipped with six sets of force-sensitive resistors 15. This allows accurate detection of the deviation direction of the upper mold frame 1 and timely alerts the staff through an alarm.

[0031] The height of the positioning detection rod 12 is greater than the height of the threaded fastening rod 13 .

[0032] The pressure bottom rod 17 corresponds to the detection column 8, and assists in transmitting and dispersing the pressure, ensuring that the pressure can act evenly on each component of the detection device, thereby improving the accuracy and stability of the detection.

[0033] like Figure 1-4 As shown, based on Example 1, the utility model provides a technical solution: preferably, the number of force-sensitive resistor sheets 15 and the number of pressure bottom rods 17 are both six groups, and the six groups of force-sensitive resistor sheets 15 are distributed in a circular array on the top of the positioning detection rod 12.

[0034] The signal transmission end of the force-sensitive resistor 15 is electrically connected to the control display 6 , and an alarm 7 is provided on one side of the control display 6 .

[0035] The top end of the detection column 8 is fixedly connected to the bottom surface of the upper mold 4 , and the upper mold 4 is fixedly connected to the bottom surface of the upper mold frame 1 .

[0036] The bottom surface of the upper mold frame 1 is fixedly connected to a cylinder 5 for driving it to open and close the mold.

[0037] The following is a detailed description of the working principle of the mold processing mold frame positioning detection device.

[0038] like Figure 1-4 As shown, when positioning detection is required, the detection base 9 is docked and installed with the bottom end of the receiving tube 10. At this time, the positioning detection rod 12 is first inserted into the bottom end of the receiving tube 10, and the positioning block 14 is docked with the built-in guide groove 11. Then, by rotating the detection base 9, the threaded fastening rod 13 is driven to tighten the thread at the bottom end of the receiving tube 10. During the rotation of the detection base 9, the positioning detection rod 12 remains in a vertical upward non-rotating state.

[0039] Then, the cylinder 5 starts to pull the upper mold frame 1 downward. As the upper mold frame 1 moves downward, the docking rod 16 at the bottom end of the detection column 8 is inserted into the receiving tube 10. When the upper mold frame 1 is offset as a whole, the docking rod 16 and the positioning detection rod 12 are no longer on the same vertical axis, and the pressure exerted by the six groups of pressure bottom rods 17 on the force-sensitive resistor 15 will change. When the pressure exerted on the six groups of force-sensitive resistors 15 is abnormal, a piezoresistive effect will occur, and their resistance value will also change with the change in pressure. The resistance change is converted into an electrical signal and transmitted to the control display 6. At this time, the control display 6 controls the alarm 7 to sound an alarm. At the same time, the control display 6 will display the abnormal pressure on the display screen above it.

[0040] It should be noted that, in this article, the terms "comprises", "includes" or any other variations are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or still includes elements that are inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element. The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to it based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
