Technical Field

[0001] The utility model belongs to the technical field of mold cleaning equipment, in particular to a laser cleaning device for a fluororesin injection mold. Background Art

[0002] Fluororesin is widely used in various high-demand industrial fields due to its excellent high-temperature resistance and corrosion resistance. Fluororesin is often used in the production of injection molds. Fluororesin injection molds are used to produce fluororesin products with high precision and strict performance requirements. They are important tools for the production of plastic products.

[0003] During the long-term production process, impurities and residues will accumulate on the mold surface, which will affect the precision of the mold and the quality of fluororesin products. Therefore, regular mold cleaning is an important part of ensuring product quality and extending the service life of the mold.

[0004] Traditional cleaning methods, such as chemical cleaning or mechanical cleaning, may damage the mold and may leave residues, resulting in the need for multiple re-cleaning to remove the residues in the mold, which in turn affects the cleaning efficiency;

[0005] However, for fluororesin injection molds that require higher precision, traditional cleaning methods are difficult to meet the cleaning needs.

[0006] Laser cleaning uses high-energy laser beams to act on the mold surface to quickly remove surface dirt and residues without damaging the mold itself. As a new cleaning technology, it has the advantages of non-contact, high precision, high cleaning efficiency, and environmental protection. Therefore, a solution is needed to solve the above problems.

[0007] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

[0009] To achieve the above-mentioned purpose, the utility model proposes a laser cleaning device for fluororesin injection molds, including a power supply and a control system, wherein the output end of the power supply and the control system is connected to the input end of a pulse laser, a beam expander is provided at the other end of the pulse laser, a reflector is provided at the other end of the beam expander, the reflector reflects the laser to a galvanometer unit, the other end of the galvanometer unit is aimed at the injection mold to be cleaned, the injection mold to be cleaned is clamped on the cleaning device, the other side of the cleaning device is connected to a servo motor, and the other side of the servo motor is connected to a controller.

[0010] In one example, the galvanometer unit includes a beam expander, a reflector, a first galvanometer, a second galvanometer and a field lens. The laser output by the pulse laser is expanded by the beam expander and then irradiated to the reflector. It is then processed by the first galvanometer, the second galvanometer and the field lens and finally irradiated to the injection mold to be cleaned.

[0011] In one example, the cleaning device includes a clamping unit and a rotating unit, and the clamping unit is fixedly embedded in the upper end surface of the rotating unit.

[0012] In one example, the clamping unit includes a base, a screw, a pressure plate and a handle. The base is arranged in a concave shape, and the pressure plate is movably arranged on the base. One side of the pressure plate is connected to a horizontally arranged screw. The screw passes through the side wall of the base and extends to the outside of the base. A handle is arranged at the tail end of the screw. The injection mold to be cleaned is placed horizontally on the upper end surface of the base and is located on the side of the pressure plate away from the handle.

[0013] In one example, the rotating unit includes a connecting plate, a fixed base, a rotating shaft and a sleeve. The lower end surface of the connecting plate is arranged in an arc shape, and the upper end surface of the fixed base is arranged in an arc shape adapted to the lower end surface of the connecting plate. The connecting plate is movably arranged on the fixed base, and the base is fixedly arranged on the upper end surface of the connecting plate. The rotating shaft is horizontally penetrated in the connecting plate, and the rotating shaft extends to the outside of the connecting plate to connect to the sleeve, and the other end of the sleeve is connected to the servo motor.

[0015] In one example, a U-shaped groove is formed on the side wall of the connecting plate, and a tapered pin is horizontally passed through the U-shaped groove.

[0016] In one example, an angle scale panel is provided on a side of the fixed base.

[0017] The laser cleaning device for fluororesin injection molds proposed by the utility model can bring the following beneficial effects:

[0018] 1. Through the high-energy laser beam directly acting on the mold surface, the accumulated impurities and residues can be quickly and effectively removed. Compared with traditional chemical or mechanical cleaning methods, laser cleaning can locate and remove dirt more accurately, thereby significantly improving the cleaning quality. Since laser cleaning is non-contact, it reduces physical damage to the mold surface, not only protecting the precision structure of the mold, but also extending the service life of the mold;

[0019] 2. By using a screw, the clamping unit can adapt to molds of different sizes and shapes. This flexibility makes the clamping unit widely used in the cleaning of various types of fluororesin injection molds; the rotating device driven by the servo motor allows the mold to swing left and right during the cleaning process, so that the laser can reach the dead corner of the mold, improving the comprehensiveness of the cleaning and ensuring that every part of the mold is thoroughly cleaned;

[0020] 3. Laser cleaning does not use chemical cleaners, so it does not produce emissions of harmful chemicals and is more environmentally friendly.

[0021] 4. The rotating unit can be automatically controlled or manually adjusted to the desired position, allowing the operator to flexibly select the most appropriate cleaning mode and angle according to specific circumstances and needs;

[0022] 5. Through the U-shaped groove and taper pin, the operator can accurately locate the rotation angle of the mold, further improving the cleaning effect and ensuring the stability of the mold during the cleaning process. BRIEF DESCRIPTION OF THE DRAWINGS

The upper end surface of the rotating unit 62 is provided with a groove 6211 matched with the bottom of the clamping unit 61 .

[0035] Specifically, the clamping unit 61 includes a base 611, a screw 612, a pressure plate 613 and a handle 614. The base 611 is arranged in a concave shape, and the pressure plate 613 is movably arranged on the base 611. One side of the pressure plate 613 is connected to the horizontally arranged screw 612. The screw 612 passes through the side wall of the base 611 and extends to the outside of the base 611. A handle 614 is arranged at the tail end of the screw 612. The mold to be cleaned is placed horizontally on the upper end surface of the base 611 and is located on the side of the pressure plate 613 away from the handle 614.

[0042] When in use, the power supply and control system provides power to the pulse laser and controls the output of the laser. The high-energy laser beam generated by the pulse laser is expanded by a beam expander and then guided to the galvanometer unit through a reflector. The laser beam is precisely regulated by the first galvanometer, the second galvanometer and the field mirror to achieve precise orientation and focusing of the laser beam. The laser beam is irradiated to the surface of the injection mold to be cleaned in a specific mode and angle through the galvanometer unit, thereby effectively removing accumulated dirt and residues.

[0043] The rotating unit is designed to be used in combination with manual and automatic modes. When the position of the injection mold to be cleaned needs to be accurately adjusted, the operator can manually adjust the rotating unit and position it by inserting a taper pin in the U-shaped groove. At the same time, the self-locking function of the servo motor ensures the stability of the mold position during the cleaning process.
