Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a cutting device for mold processing. Background Art

[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by methods such as injection moulding, blow moulding, extrusion, die casting or forging, smelting and stamping. In short, moulds are tools used to make moulded objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the moulded material. The development level of mould production is one of the important indicators of the level of mechanical manufacturing. In the production process of plastic moulds, they need to be cut.

[0003] Reference is made to Chinese patent authorization announcement number CN218425897U, which discloses a cutting device for mold processing, including a base, a first support plate and a second support plate, the tops of the first support plate and the second support plate are bolted with a top plate, and an adjusting mechanism is provided at the bottom of the top plate, a first cylinder is bolted at the bottom of the right side of the first support plate, a piston rod of the first cylinder is bolted to a chassis, a clamping assembly is provided in the inner cavity of the chassis, a second cylinder is bolted at the bottom of the adjusting mechanism, a piston rod of the second cylinder is bolted to a box body, and a first motor is bolted to the inner cavity of the box body, an output shaft of the first motor is bolted with a rotating shaft, and the right side of the rotating shaft passes through the box body and is bolted with a cutting disc; the cutting component is driven to rotate by the cooperation of the second motor, the screw rod, the threaded sleeve, the rotating block and the rotating shaft, so as to adjust the angle of the cutting disc, so as to prevent the mold from being tilted when cutting the beveled edge mold, thereby reducing the work efficiency of the worker;

[0004] By reviewing the above comparative documents, it can be seen that the prior art still has the following deficiencies, especially when cutting plastic molds. Since high temperature will be generated during the cutting process, in order to prevent the mold from softening and deforming due to high temperature, and to prevent the cutting disk of the electric cutter from being damaged due to high temperature, it is necessary to water-cool the cutting part of the mold and the cutting disk of the electric cutter. If the cooling effect of the cutting part of the mold and the cutting disk of the electric cutter is not good, not only will the mold soften due to high temperature and the cutting quality will be reduced, but the service life of the electric cutter will also be seriously affected. Since it is generally cooled by spraying water, if the waste water generated after cooling is difficult to recycle, it will cause serious waste of water resources. Utility Model Content

[0026] When the plastic mold is cut by the cutting device, the plastic mold is placed on the cutting table 3 and fixed (the fixing measures on the cutting table 3 have been disclosed in the prior art, so no further details are given in the present technical solution and are not shown in the figure). The annular cover 5 and the electric cutter 6 are driven downward by the operation of the electric cylinder 4. Under the premise that the electric cutter 6 starts working, the electric cutter 6 will cut the plastic mold through the cutting disk. During this process, the water delivery pump 11 is started to pump the cooling water in the water tank 9 into the telescopic hose 10, the water delivery pipe 8, the annular pipe 7 and the cooling nozzle 16, and then the water is sprayed to the cutting part of the mold and the cutting disk of the electric cutter 6 through the cooling nozzle 16, which is beneficial to the water cooling of the cutting part of the mold and the cutting disk of the electric cutter 6.
