Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a cutting device for mold production. Background Art

[0002] Molds refer to various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die-casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. The mold will be cut by a cutting device during the production process.

[0003] Laser cutting is to focus the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam is irradiated to the surface of the workpiece, so that the workpiece reaches the melting point or boiling point. As the relative position of the beam and the workpiece moves, the material is finally cut to achieve the purpose of cutting. Laser cutting replaces the traditional mechanical knife with an invisible beam, which has high precision and fast cutting. As a non-contact process, compared with traditional contact cutting processes (such as mechanical cutting or rotary die cutting), it has a large degree of freedom in the material, shape, size and processing environment of the processing object, and can be applied to automated processing and special surface processing; laser engraving is fine, the error can reach the millimeter to micron level, is not limited to the cutting pattern, automatic typesetting saves materials, the incision is smooth, and the processing cost is low. It will gradually improve or replace traditional metal cutting process equipment.

[0004] The focused beam enables narrow kerf widths, while localized heating allows for minimal heat input to the bulk of the material being cut. Smaller kerfs minimize the amount of material removed, while low heat input minimizes the heat affected zone (HAZ), reducing the extent of thermal deformation. The non-contact nature of the laser cutting process also reduces the risk of mechanical deformation, especially with flexible or thin materials, and reduces the risk of material contamination. Due to tighter tolerances, narrower kerf widths, smaller heat affected areas, and less material deformation, laser cut part designs can be spaced closer together on the material. This tight design reduces the amount of material waste, thereby reducing material costs over time.

[0005] However, the laser beam of laser cutting often requires a large power. When workers are in contact with the laser cutting machine, if they stare at the sparks produced by cutting for a long time, it will cause damage to the eyes and produce a stinging feeling. During the processing of the laser cutting machine, the laser emitted can highly concentrate the energy and focus it on the retina through the refractive medium of the eye to form an image, so that the energy density on the retina is significantly higher than the incident energy density on the cornea. In addition, the laser has good monochromaticity and small chromatic aberration at the fundus, so it can cause damage to the cornea or retina. When the laser shines on the skin, if its energy (power) is too large, it can cause skin damage. The damage can be repaired by the tissue, and the function is reduced, but it does not affect the overall functional structure. If the skin is exposed to light for a long time, it may cause burns and scars. Therefore, laser cutting often requires equipment or devices to clamp the material to be cut, and the ability to stably fix and clamp the mold to be cut will seriously affect the accuracy and quality of the cutting.

[0006] After searching, the Chinese invention patent with application number "CN202311402707.0" discloses a cutting device for mold production, which belongs to the field of mold production technology, including a protective shell, a supporting top plate is arranged above the protective shell, and a number of height adjustment parts for supporting and adjusting the height of the supporting top plate are arranged at both ends of the protective shell. A laser cutting head is arranged on the lower surface of the supporting top plate, and guide rollers for limiting and guiding the workpiece are arranged at both ends of the protective shell. A limiting mechanism for cooperating with the guide roller to limit the workpiece is also arranged at both ends of the protective shell. A supporting mechanism is arranged inside the protective shell, and the supporting mechanism includes an adsorption platform for cooperating with the limiting mechanism to support and trim the workpiece; the workpiece is pressed and fixed by the mutual cooperation of multiple structures, which effectively avoids the posture change of the workpiece in the later stage of cutting, thereby ensuring the cutting accuracy of the cutting device on the workpiece and making the cutting effect of the cutting device on the workpiece better.

[0007] The cutting device produced by the above-mentioned mold realizes pressing and fixing the workpiece, effectively preventing the workpiece from changing its posture in the later stage of cutting, thereby ensuring the cutting accuracy of the cutting device on the workpiece and making the cutting effect of the cutting device on the workpiece better; however, in daily use, it is found that due to the bottom support structure during laser cutting, the moving structure is at the bottom of the platform, so that arc cutting requires lateral displacement and longitudinal displacement to simulate arc motion.
