DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-2 This application is described in further detail.

[0021] The present application embodiment discloses a laser marking machine for mold processing. Figure 1 The laser marking machine for mold processing includes a left limit block 1 and a right limit block 2. The cross-sections of the left limit block 1 and the right limit block 2 are both L-shaped. The mold is clamped between the left limit block 1 and the right limit block 2. The surfaces of the left limit block 1 and the right limit block 2 for clamping the mold are both provided with a fixing groove 3. The cross-section of the fixing groove 3 is rectangular. The fixing grooves 3 on the left limit block 1 and the right limit block 2 are opposite to each other. A plurality of fixing blocks 4 are slidably arranged in the fixing groove 3. The plurality of fixing blocks 4 are arranged in a rectangular array in the fixing groove 3. The fixing blocks 4 slide in a direction perpendicular to the bottom surface of the fixing groove 3. A driving member for driving the fixing block 4 to slide is provided in the left limit block 1 and the right limit block 2.

[0022] Reference Figure 2 The driving member includes an airbag 5 arranged in the fixing groove 3, the airbag 5 is located between the bottom wall of the fixing groove 3 and the fixing block 4, and the fixing block 4 is supported on the airbag 5 in the direction of the bottom wall of the fixing groove 3.

[0023] The mold is placed between the left limit block 1 and the right limit block 2, and is clamped between the left limit block 1 and the right limit block 2. When the mold abuts against the left limit block 1 and the right limit block 2, the fixed block 4 is relatively driven to move toward the fixed groove 3. At the same time, under the action of the airbag 5, the fixed block 4 is pushed to move toward the mold, thereby forming a groove that matches the outer contour of the mold on the fixed block 4 of the rectangular array, so as to increase the contact point between the mold and the fixed block 4, thereby improving the fixing effect of the mold.

[0024] Reference Figure 1 and Figure 2 In the embodiment of the present application, the fixed block 4 is a rectangular block. The surfaces of the fixed block 4 used to fit the adjacent fixed blocks 4 are respectively provided with sliders and slide grooves for the sliders to slide. The sliders and the slide grooves are respectively located on the side walls of the fixed block 4 that are away from each other. Furthermore, the cross-sections of the sliders and the slide grooves are both dovetail-shaped. Under the action of the sliders and the slide grooves, the possibility of the adjacent fixed blocks 4 falling off is reduced, thereby facilitating the fixation of the mold.

[0025] Reference Figure 1 and Figure 2 Furthermore, the airbags 5 correspond to the fixing blocks 4 one by one, and a one-way valve 6 is provided between adjacent airbags 5; the airbags 5 correspond to the fixing blocks 4 one by one, so that it is convenient for the fixing blocks 4 to abut against the mold and fix the mold; at the same time, under the action of the one-way valve 6, it is convenient to supply air to all the airbags 5; further, when there is a possibility that a certain airbag 5 is damaged, the remaining airbags 5 push the fixing blocks 4 to fix the mold, thereby facilitating the fixation of the mold.

[0026] Reference Figure 1 and Figure 2 In order to improve the fixing effect of the fixed block 4 on the mold, a mounting groove 7 is opened at the end of the fixed block 4 facing the mold, and a fixed plate 8 is rotatably arranged in the mounting groove 7. The rotation axis of the fixed plate 8 is parallel to the height direction of the fixed block 4. An electromagnet 9 is arranged on the surface of the fixed plate 8 facing the mold. The electromagnet 9 is flush with the surface of the fixed plate 8, and the electromagnet 9 is electrically connected to the mains. An elastic member for driving the fixed plate 8 to rotate toward the mold is arranged on the fixed block 4. A hinge shaft is rotatably arranged on the fixed block 4 and located in the mounting groove 7. The fixed plate 8 is fixedly arranged on the hinge shaft. The elastic member includes a first torsion spring 10 sleeved on the hinge shaft. One side of the first torsion spring 10 is fixedly arranged on the fixed block 4, and the other side is fixedly arranged on the hinge shaft.

[0027] When the mold contacts the fixed block 4, under the action of the first torsion spring 10, the fixed plate 8 is driven to rotate toward the mold, and the fixed plate 8 rotates and fits on the mold. Then, under the action of the electromagnet 9, the fixed plate 8 is fixed on the mold, thereby improving the fixing effect of the fixed block 4 on the mold.

[0028] Reference Figure 1 and Figure 2In order to facilitate the fixing plate 8 to fit against the side wall of the mold, the fixing plate 8 includes a plurality of plate bodies 81, the electromagnet is located on the plate bodies 81, adjacent plate bodies 81 are hinged to each other, the hinge axes of adjacent plate bodies 81 are parallel to the axis direction of the hinge shaft, and the plate body 81 located at the head end is hinged on the hinge shaft; the fixing plate 8 includes a plurality of plate bodies 81, so that when the fixing plate 8 rotates toward the mold, the plurality of plate bodies 81 rotate toward the mold and fit against the mold, thereby improving the fixing effect of the fixing plate 8 on the mold.

[0029] Reference Figure 1 and Figure 2 Furthermore, a second torsion spring 11 is arranged between adjacent plates 81, and the second torsion spring 11 drives the plate 81 to have a running tendency to rotate toward the mold. A mounting shaft is arranged between adjacent plates 81, and the plate 81 is rotatably arranged on the mounting shaft. The second torsion spring 11 is sleeved on the mounting shaft, and one side of the second torsion spring 11 is fixedly arranged on the plate 81, and the other side is fixedly arranged on the adjacent plate 81.

[0030] The implementation principle of a laser marking machine for mold processing in the embodiment of the present application is:

[0031] The mold is placed between the left limit block 1 and the right limit block 2, and is clamped between the left limit block 1 and the right limit block 2. When the mold abuts against the left limit block 1 and the right limit block 2, the fixed block 4 is relatively driven to move toward the fixed groove 3. At the same time, under the action of the airbag 5, the fixed block 4 is pushed to move toward the mold, thereby forming a groove that matches the outer contour of the mold on the fixed block 4 of the rectangular array, so as to increase the contact point between the mold and the fixed block 4, thereby improving the fixing effect of the mold.
