Description

Technical Field

[0001] The utility model belongs to the technical field of laser knife molds, and in particular relates to a laser knife mold with accurate positioning. Background Art

[0002] Laser knife die is a die that cuts shapes. It is used for stamping. The normal structure is composed of a substrate and a steel blade. The substrate is usually 18mm multi-layer wood board, and transparent plexiglass (acrylic board) and plastic board can also be used instead.

[0003] Announcement No. CN216031342U discloses a laser cutting die that can achieve precise positioning. The patent uses the driving force provided by the worm gear to drive the gear and spur rack transmission to achieve precise height positioning of the blade. However, this mechanical structure is relatively complicated. In actual applications, major changes need to be made to the mold body, which makes the processing difficult. Therefore, there are major limitations in actual use and there is room for improvement. Utility Model Content

[0008] The lower die is arranged directly below the middle die, and an adjustment component is also arranged on the lower die, and the adjustment component includes a lifting part and a limiting part, wherein

[0009] The output end of the lifting part extends into the hole provided on the bottom end surface of the middle mold, and the lifting of the middle mold is realized by adjusting the assembly. When the height of the middle mold changes, the height of the upper mold can be adjusted.

[0010] The limiting part is arranged at the outer side of the middle mold and the lower mold, and the limiting part ensures that the middle mold can be lifted and lowered vertically without deviation.

[0011] Preferably, a through hole is provided on the top end surface of the lower mold, and the lifting part includes a cylinder installed in the through hole, the output end of the cylinder extends to the hole on the bottom end surface of the middle mold, and the two are bonded together.

[0012] Preferably, the limiting portion includes a connecting strip arranged on the sides of the middle mold and the lower mold, and a limiting bolt passes through the interior of the connecting strip. The limiting bolt is screwed into the interior of the middle mold. A guide column is fixed on the lower mold, and the guide column passes through the interior of the connecting strip. The guide column slides inside the connecting strip, thereby realizing vertical lifting of the middle mold.

[0013] Preferably, the inner width of the connecting strip is equal to or greater than the diameter of the guide column, so as to facilitate the sliding of the guide column in the connecting strip.

[0014] Preferably, placement grooves are symmetrically provided on both sides of the top end surface of the lower mold, and buffer blocks are placed in the placement grooves. The buffer blocks are in contact with the bottom end surface of the middle mold, so that buffer placement is achieved when the middle mold and the lower mold are fitted.

[0015] Preferably, the buffer block is bonded to the placement groove, and the top surface of the buffer block protrudes to the top surface of the lower mold, so that buffering is achieved through the protruding part.

[0016] Preferably, the cross-sectional areas of the upper die, the middle die and the lower die are equal, and a convex column is fixed on the top end surface of the upper die, and guiding is achieved by the convex column.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] Through the designed adjustment component, the height of the entire knife die can be adjusted through a simple structure. Compared with the existing structure, the adjustment component is simpler to process and has better practicality. At the same time, it can also realize modular disassembly and assembly, and the flexibility is also improved. In addition, the cylinder is used to achieve lifting. Compared with the gear lifting method, the positioning accuracy of the adjustment component is higher, which improves the shortcomings of the existing knife die in use.
