Description

Technical Field

[0001] The present application relates to the technical field of mold production, and in particular to a mold production hole-opening device. Background Art

[0002] Mould production hole drilling refers to the operation of drilling holes on the workpiece or mould parts during the mould manufacturing process. Hole drilling methods usually include drilling, milling, laser cutting and other technologies. When drilling holes in mould production, it is necessary to select the appropriate hole drilling method according to the requirements of the workpiece and the needs of the mould design, and ensure that the hole position, size and precision meet the requirements. Drilling is a common hole drilling method, in which the drill bit rotates and pushes downward on the workpiece or mould parts to form a circular hole. In the mould production process, the quality of the hole drilling directly affects the quality and precision of the final product. Therefore, when selecting the hole drilling method and performing the hole drilling operation, it is necessary to strictly control the processing parameters to ensure that the hole position, size and surface quality meet the design requirements.

[0003] Many molds need to open multiple holes at equal intervals. The traditional method is to do it through manual measurement, which is inconvenient. "A mold production hole-opening device with publication number 'CN220362291U'" discloses a positioning mechanism set inside the second cavity. When the drill rod punches the first hole, the pull rod is pulled, and the second spring is compressed. Then the first slider is moved to move the positioning rod to the top of the first hole. Then the pull rod is released, and the rebound force of the second spring can move the positioning rod to the inside of the first hole. Then the second hole can be opened, and the holes opened are the same in spacing. However, the above-mentioned hole-opening device requires manual operation every time a hole is punched, which increases the burden on the staff, and the spacing is difficult to adjust accurately and is not accurate. Therefore, in order to solve the above problems, the present application provides a mold production hole-opening device.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

The top plate 3 is provided with a moving groove 11, and a moving block 14 is slidably provided in the moving groove 11. A processor 15 is fixedly provided on the upper wall of the moving block 14. The processor 15 is connected to the upper contact plate 803 and the lower contact plate 804 for communication. Whether the upper contact plate 803 and the lower contact plate 804 are in contact or not is processed by the processor 15 to send instructions to the first telescopic rod 7, the cylinder 4 and the second motor 9. A first screw 12 is provided through the side wall of the top plate 3 and is rotatably connected. One end of the first screw 12 located inside the moving groove 11 is rotatably connected with the side wall thereof.
